The low voltage solution 

Gateway (LGW200) 

The LGW200 is the smart metering gateway of the Aranuka system, made by Power Plus 

Communication. It enables the real-time readout of smart meters. The LGW200 connects the 

BPL network to meters via standard short range interfaces such as Wireless-M-Bus or RS485, 

RS232, M-Bus and Current Loop (wired) and also narrow band PLC. This system allows easy 

integration of meters from different manufacturers in order to build a multi-utility (electricity, gas, 

water, heat) metering solution. 

Repeater (LR200) 

The LR200 extends the coverage of the BPL network by regenerating the data signal 

dynamically. It serves as smart nodes in a meshed network structure. 

Headend (LH200) 

The LH200 connects the BPL network to the backbone via an Ethernet interface.

The medium voltage solution 

Coupler 

With the BPL medium-voltage coupler a medium-voltage grids can be turned into broadband 

data networks. It has been developed specifically for the transmission of broadband signals 

over ground-cables and overhead lines. Together with the MV200 BPL modem, this coupler 

enables data transmission rates up to 30 Mbps. 

MV200 

PPC's medium-voltage modem MV200 is able to transmit data on cables with a data rate up to 

30 Mbps, in combination with the BPL coupler.

Basic informations 

Area: 12 square km 

Population: 5 000 people 

Number of electricity customers: over 1 500 

Number of stations MV / LV: 12 (two MV rings) 

MV cable length between stations: from 200m to 1800m 

Type of MV cable: Underground 

Aim of installation BPL communication over MV grid: 

• implementation of telecommunication connections between all electricity meters 

installed at the customers supplied from the LV and fiber-optic backbone network of 

energy supplier/distributor 

• implementation of telecommunication connections between RTU planned to be 

installed in substations MV / LV and supervising system of energy grid (for mapping of 

switch location, measurements of MV/LV grid parameters, access control)

Measurements - Link for connection between ST9–GPZ (1.2km) 

The following Figure shows the link quality. One can see that only the first two bands can be 

used with QPSK-modulation for data transmission due to the attenuation of the 1.200 meter 

long cable.

Measurements - Link for connection between ST9–GPZ (1.2km) 

Link ST9 – GPZ (1.200 meter) 

Two Bandwidth measurements have been made. For this test, the devices in ST-3 have been 

powered off. 

The first was made with the default configuration of the Aranuka modems, for meshed BPL 

infrastructure. The bandwidth was 1.45 Mbps. 

The second measurements where done with optimised configuration for Point-To-Point Links. 

With optimised configuration, on this communication link increased from 1.45 Mbps to 2.45 

Mbps in average. 


19


Measurements - Link for connection between ST3–GPZ (800m) 

The following Figure shows the link quality between GPZ and ST3. One can see that four of 

seven bands can be used, with all types of modulation for data transmission on the 800 meter 

long cable. 

The average bandwidth was 6 Mbps

MV BPL - conclusions 

• Low implementation costs - comparable with narrowband PLC technology 

• Higher speed of transmission than narrowband PLC technology offering 

• Easy to install 

• A good way to extend the TCP / IP backbone network to the MV / LV station 

• Allows the coexistence of multiple systems, not only Smart Meterig or Smart Grid 

The surveillance system for energy networks 

Control of street lighting and traffic lights 

Access control system 

• MV BPL is an alternative to Fibre-Optic link 

Cheaper to implementation 

Faster to implementation 

Often the only way to use in an urban area 

• The possibility of extending the TCP/IP backbone to the LV grid area
