Choosing the right route

The PMR market has

expanded rapidly over

the past few years, driven

by customers looking to

migrate from analogue to

digital radio systems. They

now have a wealth of different options to

choose from with TETRA, TETRAPOL,

P25, DMR, dPMR and NXDN all vying for

a slice of the market.

Major public safety organisations

tend to choose TETRA, TETRAPOL or

P25, thanks to their well-developed

range of features, strong security and

encryption capabilities.

But for second tier security organisations,

enterprises and commercial users looking

for a more affordable, less feature-rich

option, the digital choice comes down to

DMR or dPMR and its NXDN variants. But

there is some confusion among customers

as to which one to choose.

GS Kok, vice president of research and

development at Hytera, says they should

not worry. ‘A year ago I wrote an article

about the transfer of analogue to digital

radio and I said, just embrace it and

don’t wait to see if DMR or dPMR

will be the main standard to be adopted.

Waiting for a new standard with a wider

channel requirement will take five years

to develop and a further five years to

come to market. Now we have DMR

and dPMR, so just use them – they

won’t disappear.’

Hytera still produces and supports a

wide portfolio of licence-free and analogue

radio equipment with its TC range of

portable terminals, TM portable radios,

TR repeaters, and its analogue MPT1327

trunking system, but Kok says the

company is concentrating its investment in

digital standards.

Hytera is a member of both the DMR

and the dPMR Associations, but while not

ignoring dPMR, most of Hytera’s research

and development efforts are centred on

The migration from analogue to digital radio is gathering speed

and there are now a range of standards to choose from. GS Kok,

vice president of research and development at Hytera, tells

Wireless editor James Atkinson what the company is doing to

take advantage of this trend.

developing DMR, TETRA and the homegrown

Chinese standard PDT (Professional

Digital Trunking) products.

‘We’ve been very busy,’ reports Kok. ‘We

had to open a new factory in Shenzhen this

year, as we couldn’t cope with the market

ramp up to digital.’



The new manufacturing facility in Baolong

Industrial City in the Longgang District of

Shenzhen has a ground area of 49,888m2

and building area of 113,434m2, or ten times

the manufacturing space the company

had previously. It is expected to create

a production value of around US$750m

(£480m) annually once it is running at

full capacity.

The Baolong facility houses more than

1,100 employees and is equipped with

advanced production equipment, including

automated production lines designed

to enhance production efficiency. It also

contains environmental test laboratories,

which will complement Hytera’s existing

R&D centres.

‘At this time, we see Hytera as being very

strong globally in DMR, as we have got one

of the biggest portfolios,’ says Kok.


Hytera now offers a complete DMR

portfolio for both conventional and trunking

modes, including portable and mobile

radios, covert radio, intrinsically safe

radio, repeaters, data application, multisite

IP connection, a simulcast system and

trunking infrastructure.

In 2011, Hytera became the first

manufacturer to release a DMR Tier III

solution, which offers much the same

functionality as TETRA, although without

the same breadth of features. ‘Guatemala

has been using it for the past two years and

we showcased it this year at IWCE in Las

Vegas,’ says Kok.

‘We’ve sold quite a few Tier III systems

already in Thailand, New York and other

places we can’t disclose as the contracts are

not signed yet.’

The company has recently completed

DMR Tier III mandatory and optional

IOP (interoperability process) tests using

Hytera terminals and Tait Communications

infrastructure, as specified by the DMR

‘By end of year we should

also have a second series

of DMR products and our

for digital migration

Ramping up: Hytera recently opened a new factory in Shenzhen to meet the increasing global demand for digital PMR equipment

Association, and will soon get its official

IOP certification.

Kok reports that the DMR PD705 series

portfolio is largely complete. ‘We’ve got

nearly all the frequency bands required now,

so we will focus on developing slimmer,

more efficient and more feature-enhanced

products,’ he says. ‘By end of year we

should also have a second series of DMR

products, and our DMR ATEX radio – which

we’ve been demonstrating at shows this

year – should be commercially available,

with a TETRA ATEX version due in 2013.’

Earlier this year, Hytera released its

covert DMR radio in the shape of the X1e

(a TETRA version is due for release next

year) – the smallest and slimmest radio of its

type. Kok says that the DMR covert range is

being extended with the X1p, which comes

with keypad and display, and the X1s, a

simplified version with just six keys.

‘We are concentrating on DMR because it

is cost effective and affordable,’ says Kok.

‘We think the digital pick-up will be much

faster and more acceptable, especially in

South East Asia and India, where we believe

they will embrace DMR more.’

One of the reasons DMR is so attractive

for analogue users wanting to move to

digital is that it uses time division multiple

access (TDMA), retaining the single 12.5kHz

channel width and dividing it into two

alternating time slots. Each time slot acts as

a separate communication channel with an

equivalent bandwidth of 6.25kHz. However,

the channel as a whole keeps the same

profile as an analogue 12.5kHz signal.

This means it will fit into existing licensed

PMR bands.

‘This ease of migration and ease of use

is the key for the next two to three years of

digital migration,’ says Kok.


The dPMR standard, on the other hand,

uses frequency division multiple access

(FDMA) and separates the 12.5kHz band

into two true 6.25kHz channels. dPMR

has the advantage over DMR in that it was

largely developed to avoid IPR, licences

and royalties, so it can be cheaper. But as

Kok points out, it has the disadvantage

that in some countries the existing 12.5Khz

PMR licences would have to be refarmed

for 6.25kHz – a costly, difficult and timeconsuming


‘Governments are cash strapped at the

moment and they can’t afford to give

regulators a lot of money to refarm the

frequencies,’ says Kok. ‘They don’t want to

go through another round of renegotiating

licences like 25kHz to 12.5kHz.

‘One thing about dPMR is that it is easier

to design,’ continues Kok, ‘because of the

differences between TDMA and FDMA.

With FDMA you just change the modulation

to fit the case, whereas with TDMA you

have to pulse the signal, so timing becomes

very critical and that makes the design

more complicated.’

Each standard has its advantages, but

as an indicator of which is proving more



popular, Kok points out that the DMR

Association is far larger than the dPMR

Association. He adds that IMS Research

reports show that Motorola Solutions has

sold more than one million DMR terminals,

while the combined sales figures for the

main dPMR vendors are far below that total.

‘The future for DMR is very bright,’ says

Kok. ‘We won the battle for the professional

market, but we are still working hard to

get a solution for the commercial market.

The next step is to develop a very low-cost

radio for DMR, but every manufacturer will

be hard pressed to provide that. Can we

provide a one-use $20 radio from Walmart

I think Family Service Radio will remain,

as I don’t see the point in changing the

frequency. It would be very challenging to

provide that solution.

‘We are under tremendous pressure to

develop an entry-level DMR product, so we

can accelerate the change from analogue

to digital. But this forces us to be more

creative and come up with better products

at cheaper prices. Our objective is to release

something next year for the entry-level

DMR market.’

Kok continues: ‘Our research team is

very busy, especially in China, where it is

mandatory for the police services to migrate

to digital by 2016. That’s a very tall order, as

there are a lot of analogue radios to replace

and the replacement must be in a similar

cost range as those analogue radios.’


As a result of this, Hytera is also heavily

involved in developing China’s alternative

to DMR and dMPR in the shape of the PDT

(Professional Digital Trunking) standard,

which is being driven by the Information

and Telecommunication Bureau of the

Chinese Ministry of Public Security.

PDT is broadly similar to the ETSI

standard for DMR Tier III, in that it uses

two-slot TDMA in 12.5kHz channel spacing,

although there are some differences.

Kok explains that PDT is very

China orientated. The stimulus for its

development was the Beijing Olympics,

where the government had to provide an

affordable two-way radio system.

‘They looked at TETRA, but the cost was

prohibitive,’ explains Kok. ‘Look at how

many cities need to be digitised. China has

had to bow out from TETRA – it’s only some

big cities such as Shanghai, which can pay

for it, that are adopting it.

‘But if you take somewhere like Chengdu,

which is remote, but still a very big city in

Inner Mongolia – it has a large population,

but not much economy, so the only choice

is for something that replaces its ageing

MPT system with an affordable product that

expands the feature set.’

China looked to embrace an open

standard, but found that adopting DMR

meant paying too much in licences and

royalties, so the government and others,

including Hytera, got to work on developing

the more cost-efficient, home-grown PDT

Retail win: Hytera recently upgraded

radio communications at River Island’s

distribution centre in the UK

‘The future for DMR

is very bright. We

won the battle for

the professional

market, but we are

still working hard to

get a solution for the

commercial market’

solution. The company is now the main

supplier of PDT equipment. ‘You can put IP

into it, but that IP is free for all to use, since

you had been consigned by the Government

to draft the Standards’ says Kok.

He adds: ‘In China, the migration to

digital is only just starting in public safety

and utilities, but once the police move

then the professionals will follow. PDT

is only just rolling out this year, but we

expect the speed to pick up next year. We

need to get a tier of products that will

persuade the commercial people to follow

after the professionals. So, there is a long

way to go in China – 80% of the market is

still analogue.’

Kok believes that with the Chinese

government pumping in RMB200m to

mitigate the police analogue radios to

digital, people are looking to partake in

R&D in China. ‘It’s a big market and they

want a piece,’ he says. He also thinks that

despite PDT’s China focus, its functionality

and affordability will make it attractive to

other countries, especially developing ones.

Tests are underway in Vietnam, Indonesia,

Thailand and Cambodia, and there have

been enquiries from Latin America, the

Middle East and even Europe.

The focus in Europe, however, has until

recently largely been confined to DMR.

But the acquisition of Rohde & Schwarz’s

PMR division (now known as Hytera Mobil

Funk), which was finalised earlier this year,

means Hytera can now also offer a full

range of end-to-end TETRA solutions.

Naturally, Hytera faces stiff competition

for both DMR and TETRA in a mature

market such as Europe. Kok says: ‘When

there is a lot of competition, manufacturers

have to be more creative to capture bigger

markets and gear it towards what the

customer wants. Look at Apple’s iPhone:

there is nothing really new about it, but

what it does is package it in a way that the

customer is comfortable with, and load it

with apps that are so much easier to use.

‘When Steve Jobs was a young man he

focused a lot on R&D, but it’s not about

having the most advanced technology; it

is about utilising it in a way that makes it

easier for customers and more profitable

for your company,’ says Kok.

Options for change: In China the police are choosing the PDT standard, but in other regions Hytera is mainly offering its DMR and TETRA products


When it comes to TETRA, Hytera has an

ATEX radio and a covert radio in the works

for next year to add to its PT580H portable

terminal and MT680 mobile. The Rohde

& Schwarz developed ACCESSNET-T IP

base stations are also available. The next

key development in both TETRA and DMR

is how to integrate them with 4G LTE for

broadband services.

‘Some Public Safety and Security

customers are looking at expanding to

LTE or upgrading to it,’ says Kok, ‘so we

have had broadband planned in since

2009. A multi-core, multi-band product is

something we are developing right now.

In our future five-year road map we have

TETRA and DMR co-existing with LTE, so

we are working on another platform that

will integrate narrowband and broadband.

It is more of a long-term goal, as we need to

define broadband in China and participate

in global market standardisation.’

TDD-LTE will be the option used in

China, as it was developed there, but what

spectrum band will be chosen is still up

for discussion. In the meantime, Chinese

manufacturers will need to meet other

global LTE standards currently being rolled

out, which range from 400MHz in Europe,

and 700MHz in the US, to 2.6MHz in China.

‘Actually, it’s really just about getting the

RF to support the modulation,’ says Kok.

‘The RF is independent of what the RF

modulation does, so the RF chip set will just

need to be developed for the particular LTE

band that is chosen. Hytera Mobil Funk can

support 3G/4G interoperability.’

In the interim, Rohde & Schwarz is

working on TETRA enhanced data service

(TEDS) requirements. ‘We should be TEDS

ready within less than 12 months,’ reports

Kok. ‘We can’t afford not to be ready, as

Motorola and Cassidian are already there,

and until LTE becomes fully mainstream

TEDS will be there as an option. But it will

mainly be used by the police, as I don’t see

TEDS picking up a big field of users.

‘It was a brilliant standard in early 2000,

but then nobody developed a product, so

it may be a little bit too late now that LTE

has come along. The advance of technology

is much faster than suppliers can keep up

with and I think TEDS will suffer as a result.

Manufacturers won’t make a lot of money

from it,’ says Kok.

‘I don’t know if LTE will become the

final broadband solution,’ he continues. ‘If

something new and better turns up people

will turn to it very quickly. People are

becoming more intelligent and the younger

generation is choosing the tech they want to

embrace, rather than taking the tech offered

by big companies.’

Kok sees digital radio of one sort or

another as the only conceivable option now.

‘Those who embraced digital in the early

days are being rewarded,’ he says. ‘The rest

need to migrate to digital or else they will

be left behind. No one will be able to talk

to you. Analogue is a good technology, it’s

served us well for 50 years, but customers

will be hard pressed to get manufacturers to

support them for ICs. They’ve got to make

money, so analogue radio users will be left

high and dry unless they move over

to digital.’

It is a fairly stark warning to customers,

but there is a range of digital options out

there now and DMR does offer customers

the opportunity to move at their own pace,

as DMR radios will work with analogue

ones. This means customers do not have

to find the cash to change over their entire

fleets in one go. And with a full range of

TETRA, DMR and PDT equipment in its

armoury, Hytera is clearly well positioned

to take advantage of that migration as it

continues and picks up speed over the next

few years.



DMR for Euro stadium

Poland’s Municipal Statium

Poznan upgraded its staff

communication system in

preparation for the Euro 2012

football matches, selecting

Hytera’s DMR digital

communications solution to

facilitate its operation

Staging major sporting

events requires a high

degree of planning and

organisation. A vital part

in ensuring such events

are a success is providing

robust and reliable communications to

organisers and staff.

The 2012 UEFA European Football

Championship in Poland and Ukraine

was no exception to this rule. The

Municipal Stadium Poznan, in the city

of Poznan, was one of the four venues in

Poland chosen to host some of the games.

The Euro 2012 competition kicked off on

9 June 2012 and three Group C matches

were played in the stadium.

Originally built in 1968, the Municipal

Stadium Poznan is the home ground of

two Polish football clubs – Lech Poznan

and Warta Poznan. From 2003 to 2010,

the stadium underwent a thorough

reconstruction to prepare for Euro 2012

and reopened on 20 September 2010.

The stadium has the capacity to host

a crowd of 43,000 people, so efficient

communication and co-ordination among

staff is critical. To make sure the three

matches ran smoothly, the operator of

Municipal Stadium Poznan decided to

upgrade its communication system early

in 2012. It chose Hytera’s DMR solution

for its reliability and versatile functions.

Alfa Radio, a Hytera dealer in Poland,

was selected to deliver 132 PD705, 10

PD785 DMR handheld radios and two

RD985 DMR repeaters together with one

SmartDispatch to upgrade the system.

The equipment and RF solution had to

take into account the steel and concrete

architecture of the stadium and was

designed to ensure full radio coverage

was provided in and around the stadium.

‘Alfa Radio was selected

to deliver 132 PD705, 10

PD785 DMR handheld

radios and two RD985

DMR repeaters’

Voice dispatching was available for

operator directors in the control

centre to all the staff via the

SmartDispatch system. Moreover,

Hytera’s flexible grouping function meant

that staff in different working groups

could access group communication

without causing interference to other

talk groups.

Operators also had access to enhanced

emergency handling capabilities via

other powerful security functions, such

as the Man Down facility. The stadium

is completely covered by a roof, which

increases echoes, so to combat the

increased noise levels, Hytera offered

specified earpieces with microphones to

the staff.

Now that the Euro 2012 championship

is over, Municipal Stadium Poznan’s

DMR communications system will

continue to be used in the stadium for

daily operations and events held at the

venue, including all the home matches of

Lech Poznan and Warta Poznan.

The wireless triathlon

The historic Swedish town

of Kalmar hosted its first

Ironman competition in

August 2012. The event

comprised a gruelling

3.86km swim in the

Kalmar Strait, a 180.2km bicycle race and a

Marathon run of 42.195km.

Approximately 1,500 athletes took part

in the Kalmar event, while visitor numbers

were estimated at more than 40,000.

Naturally, the event organisers, Kalmar

Triathlon AB, needed to have reliable and

robust communications to ensure the

competition went smoothly. The original

plan was that the race would be

co-ordinated using GSM/3G phones.

However, the organisers realised this

would not provide the required quality of

service. For example, it was not possible to

establish communications between the race

controllers and the emergency services. Plus

the ESPN television team needed access to

fast communication services.

The issue was brought to the attention

of Stockholm-based wireless distributer

Zodiac through one of its local dealers,

Dialect Lemab Kalmar, which asked

whether Zodiac could offer a solution.

Kalmar Triathlon had a number of key

requirements that had to be met, including:

● A cost effective solution for shortterm


When the organisers of the Kalmar Ironman competition in

Sweden needed a temporary communications network they

turned to Hytera’s DMR solution

● Wide area surface coverage for

handheld radios

● Fast and reliable connectivity between


● Easy operation for users with only

minimal training

● Good sound quality

● Uptime of handheld devices during the

whole duration of the event

● Rugged devices that could withstand

impact and moisture

● The possibility of combining the

wireless system with GPS positioning

for use at other competitions in Sweden.

Zodiac worked with Dialect Lemab to

identify the right equipment and design

for a temporary wireless network, which

involved using the following Hytera DMR

equipment: three RD982 base stations; 36

PD785 hand-held radios; six slot chargers for

all the handheld radios; and accessories such

as ‘secret service’ style headsets.

The solution offered IP over internet

roaming between base stations, while the

deployment of one RD980M in repeater

mode in every base station provided wider

area coverage than conventional radios. The

design of the network architecture provided

some overlap in the competition area for

added resilience.

As well as supplying Hytera equipment,

Zodiac also helped with system installation

and programme files, telephone support

throughout the deployment, and backup

with spare radios and technical skills during

the competition phase.

Tobias Borg, one of the managers for the

Ironman event, said that the competition

would not have been possible without the

radio system supplied by Hytera. He added

that it was simple to use and the features

available exceeded requirements. Organisers

have pre-booked the same system for 2013.

Göran Engström at Rescue Kalmar said

that from the emergency services’ point of

view the communication between organisers

and the authorities was quick and clear

thanks to the efficient radio network.

Thomas Matsson of Lemab Kalmar

said the company was very pleased with

the outcome of the co-operation between

Hytera, Zodiac and Lemab and that the

deployment of the network was easy thanks

to the instruction and support from Zodiac,

despite the fact that Lemab was not entirely

familiar with the DMR technology involved.



Bringing two-way radio cl



based in


Connecticut in

the US, is the

largest trunked radio network operator

in the State of Connecticut. Its trunked

radio communications network covers the

whole state and provides services for a

wide variety of end-users including police,

firefighters, healthcare, enterprises and

taxi companies.

Right from the start, Marcus has strived

to deliver technical excellence to its

customers in the field of two-way wireless

radio services. Over the past 33 years, it

has taken part in countless events where

its technical know-how and agility were of

vital importance in delivering successful

outcomes. The Marcus Communications

team remains dedicated to its customers

and community, while continuing to

make significant breakthroughs in

new technology.

However, the global rise in digital

Marcus Pilot System Coverage Map (Mobile)

As demand for improved communications increased,

Connecticut-based analogue trunked radio network operator

Marcus Communications realised it had to upgrade its existing

services to business and public safety users, and so it turned to

Hytera for an improved DMR Tier III digital system

communications technology prompted

the company to review its services.

At present, Marcus provides two-way

radio leasing and network maintenance

for business users, along with a full set

of communication services for public

safety users. But as the demand for more

and better communications increased,

Marcus gradually realised the inferiority

of its analogue LTR (logic trunked radio)

communication and data services.


End-users often complained that its LTR

network delivered unclear audio quality

and pointed to existing blind spots in its

coverage. In addition, taxi companies

maintained a wait-and-see attitude towards

further investment, as the network was

unable to provide adequate levels of GPS

service for tracking the whereabouts of

taxicabs. Finally, public safety users looking

for a digital option were put off leasing

Project 25 (P25) equipment supplied by

Marcus, because of the high rental charges.

The limitations of Marcus’ LTR analogue

radios for voice communications and data

services, along with the off-putting cost of

its P25 equipment, lost the company a lot of

business. It needed to find a cost-effective

alternative to its analogue product, which

could provide a more advanced technical

solution for its range of customers.

The company had to find a digital

solution capable of providing trunked

radio services, but one that was more

cost-effective than the P25 equipment

commonly used by first responders in the

US. Advances in the DMR (digital mobile

radio) standard over the past two years

mean that DMR Tier III now provides a

trunked version.

● Level 5: Crystal clear without noise

at the background

● Level 4: Good voice quality

● Level 3: Acceptable and

comprehensible voice quality with

some background noise

● Level 2: Barely comprehensible with

high noise background

● Level 1: Not comprehensible

H: For Haddam Site

Marcus assessed the various DMR (digital

mobile radio) products on the market and

was particularly impressed with the high

quality of Hytera’s equipment. As a result,

Marcus decided to replace its existing

network in stages with Hytera’s DMR Tier

III trunking system.

Hytera ensured its DMR Tier III trunking

equipment met the particular demands of

its customer. In the first phase, three DMR

trunked base stations were deployed in the

LTR network in Box Mountain, Avon and

Haddam. This provided coverage in the

technology, achieving a better

audio quality when compared

with the old analogue radio

system, which provides a better

user experience for Marcus’

customer base.

New services: Bruce Marcus, owner and CTO of Marcus Communications opted for Hytera

trunked DMR Tier III system to upgrade his existing analogue network

towns of Manchester, Hartford, Avon and

Haddam. The final network rollout saw

a total of 20 DMR trunked base stations

located across the state to provide coverage

across the whole of Connecticut.

Compared with the previous LTR

analogue network, the newly-built

Hytera DMR network is bringing Marcus

operational cost savings and higher

network efficiency. As a result, the

company plans to extend its successful

partnership with Hytera and make more

use of its products.

Hytera’s DMR Tier III network has

doubled the user and traffic capacity from

900 to 1,800 using the same amount of

equipment or less (three base stations with

each base station having four RF units),

which has reduced costs considerably.

Hytera terminals adopt advanced digital


DMR technology uses TDMA

two time-slot technology, which

divides the 12.5kHz bandwidth into two

6.5 kHz time slots to support two

simultaneous communication channels. This

greatly enhances the spectrum efficiency and

system capacity, while also improving the

battery life of the radios.

The Hytera DMR Tier III system meets

the 95% coverage demand of Marcus’

network perfectly (public safety users:

95dBm downlink, business users:

105dBm downlink).

Bruce Marcus, owner and CTO of

Marcus Communications, said: ‘We

are impressed with the quality of the

equipment and are looking forward to a

successful partnership. We talked to one

of our employees on a handheld radio

35 miles from us, while we were in an

indoor mall, with excellent results.’ The

successful rollout of Hytera’s equipment

in Connecticut should prove a compelling

App that tracks indoor an

The SafetyNet Locator

application developed by

PMR Products provides

administrators with a simple

and easy means of tracking the

deployment of their Hytera

radio subscriber fleet in both

indoor and outdoor locations

The SafetyNet Locator

developed by UK

firm PMR Products is

one application in the

company’s SafetyNet

Digital suite of software

programs designed to access audio and

data information from radio equipment.

SafetyNet connects to a range of

communications devices through gateways

or decoders and can include DMR and

TETRA private radio networks, pagers,

DECT and short-range radio alarms

SafetyNet Digital software is PC based

and provides control room facilities for

managing and monitoring all audio across

the radio network being managed. Tools

are also provided for recording all audio,

dispatch facilities, lone worker protection

schemes, text messaging and handling

personal alarms and general status

updates. It also handles all location

update information, which is passed to

SafetyNet Locator.

The Locator product range combines

location beacons, Locator receiver

modules, gateways, decoders and

SafetyNet PC-based software in a fully

integrated package that can be expanded

easily through additional modules.

Locator software takes the position

information received to provide a user

friendly display of all radio users’

locations on a set of maps or schematic

diagrams. The SafetyNet Locator display

also provides a summary of the status of

each radio deployed, for example, whether

an alarms has been activated.

Additional tools are provided to

automatically convert a location to a text

or audio message which can be relayed out

to other radio users for emergencies

or announcements.

Locator Zones: The position of radios can be displayed on a variety of mapping options


For indoor location, a Locator receiver

device is fitted to each radio and this

detects users’ movement via strategically

placed beacons around a site. The beacons

can be fixed in discreet positions to cover

d out

all key areas and can run from internal

batteries for a period of between two and

five years reducing installation overhead.

Mains operating beacons are also available.

The beacon positions are determined

and installed to meet the security or safety

requirements of the site. Furthermore, a

greater number of beacons lends a greater

accuracy of positional information. A full

survey kit and remote programmer permits

individual beacons to be configured easily

without needing to remove the beacons

from their original location.

An important feature of the Indoor

Locator is its use of the existing radio

infrastructure. Spare capacity on the

radio channel is used for sending

updates in short data messages, thereby

minimising the extra expense of additional

data backhaul capacity. In busy networks,

the system is scalable, allowing additional

infrastructure to be added to provide

dedicated data backhaul.

Outdoor position over wide areas is

provided by radio units equipped with

GPS receivers. Radio user positions

are updated to SafetyNet and can be

plotted onto maps via the SafetyNet

Locator application or simply logged for

archive purposes.


Locator can show the position of

subscribers on a number of different

map formats, which are preloaded

at configuration time as tiles. As

images are held on the computer

permanently, an internet connection is

not necessarily required.

The users can be presented with

location information on a map or image

types including:

● Ordnance Survey Street maps

(United Kingdom)

● GPS maps exported from

OpenStreetMaps or similar

● Overhead photographs

● Schematics or CAD generated

3D images

● Annotated drawings

For outdoor GPS locations, a precise

position is shown on the maps within the

ranges specified; for indoor locations users

will be shown within a boundary or zone

defined on the appropriate map.

Steve Clarke, Director, PMR Products,

says: ‘The SafetyNet Locator offers

resellers of Hytera radio equipment an

opportunity to upsell the application to

make their proposition more attractive to

the end user.

‘It gives them a way to provide the end

user with added value and it is a way of

differentiating themselves and Hytera in

the market.’



PMR Products in conjunction

with Hytera have developed

an accessory unit called the

Locator Receiver module that

utilises the radio to transmit

location information to the

SafetyNet software through base

station and fixed mobile based

decoder interfaces.

The Locator receiver module fits

onto the accessory side connector.

The module also provides an audio

accessory audio jack socket providing connections for

microphone, PTT and earpiece.

Indoor and outdoor positioning is available on

TETRA and DMR radios supplied with the (MD) GPS

option. The module is interchangeable between DMR

and TETRA products when suitably programmed.

The Locator receiver is manufactured under licence

by Hytera and is fully approved and tested for use on

the radio equipment specified.

Sound the alarm

Danish company Zonith

specialises in developing

software for professionals

who have to deal with

alarms that range from

simple notification

solutions to large alarm

handling systems

Zonith’s Alarm Control

System (ACS) is a

software application

that enables customers

to link alarm systems

to Hytera radios and

provides customers with the ability to

combine alarm messaging and voice into

one single device.

The software translates the alarm

system protocols into Hytera’s DMR

and TETRA messaging formats and

automatically selects the person best

suited for the task using action filters

and a scheduler. Customers can remotely

accept, decline, escalate and close alarms

or tasks using a Hytera radio keypad.

The ACS is available in Lite and Plus

versions depending on the requirement.

The ACS Lite is an entry-level scalable

package that enables organisations to link

a single alarm source to digital radios.

ACS Plus is a more intelligent system

that supports multiple alarm sources

and dispatch media, and provides action

filtering, alarm acknowledgements and

alarm escalation.

One of the key advantages of the ACS

is that it is both a flexible and a scalable

application that can be expanded into

a fully integrated lone worker and

indoor positioning system using Zonith

Bluetooth positioning beacons.

The ACS connects to the Hytera radio

system via USB and supports group and

individual messaging. It also supports

multiple alarm inputs including ASCII,

RS232/ 486, SMTP, SNMP, I/O, XML,


The system comes with a personal

alarm scheduler, which enables

administrators to define alarm escalation

paths for intelligent dispatch of alarms

and tasks.

The ACS picks up alarms from any

alarm source. It pairs the alarm with

the correct on-duty employee through

the intelligent scheduler, ensuring

that problems get handled at the right time

by the right person. The alarms are sent as

text messages directly to this person on his

or her digital radio, pager, mobile phone

or email account, depending on how

critical the alarm is.

The integrated watch schedule feature

allows the manager to organise the work

schedule in the alarm-handling software

itself, ensuring that alarms are always

dispatched to employees who are at work

at the time of the dispatch.

The system enables alarm prioritisation,

which saves resources by handling alarms

at the best possible time. The priority

can influence which dispatch media the

administrator uses for the alarm, and it can

influence when the alarm is dispatched to

the receiver. Typically, a low-priority alarm

raised at the weekend is dispatched the

following Monday morning by mail, while

a high-priority alarm will be dispatched

immediately by DMR or TETRA.

ACS also has the ability to filter test

and fault alarms, which helps to reduce

the number of unnecessary false alarms.

The alarm quarantine filter stops multiple

incoming alarms being triggered in the

event of a large system failure.

Features include a free-hand text

messaging interface, and the ACS can be

configured to provide a centralised lone

worker service, which regularly sends

‘Heart Beat’ text messages to Hytera

radio users. The ACS will immediately

raise an alarm if a Hytera radio user fails

to respond to a ‘Heart Beat’ message.

The ACS can also be accessed through

an internet browser. The web interface is

mainly for managerial purposes, and the

radio will always be the main interface in

the daily use of the system.

Other notable features are a

customisable alarm summary display

screen and the ability to support

DMR Panic button messaging. ACS

can also simultaneously send alarms to

TETRA, DMR, SMS, email, DECT and

Paging devices.

The system also guarantees delivery

receipts and has a messaging retry

feature to ensure that people receive

alarms. ACS comes with a full audit

trail capability, logging and reporting

all alarm activities, including delivery

receipt, acknowledgment, escalation and

alarm closures.
