Low Power Radio Data LoggerLow power radio technology has been developedfollowing years of experience of deploying AMR systemsin the UK and USA. These products have been purposelydesigned to maximize range and penetration withina building. Data is transmitted in the 868 MHz ISMradio band using a technique called ‘narrow bandtransmission’. The radio operates at a lower data ratewhich sets it apart from other systems (such as Wi-Fi,Zigbee and Bluetooth) to provide better penetration ofbuildings and increase range.The radio consists of two parts:• Transmitter (Merlin)- Zone Zero ATEX Approved- Multi utility- Many applications outside of utility monitoring- Very easy to install• Receiving data Hub (Kestrel)The Kestrel can receive transmissions from a group oftransmitters (Merlins) and will concentrate the data forupward delivery over a wide area network, which canbe Internet or GPRS enabled.In the case of Internet, the data can be delivered nearreal time to a secure Web site or customer’s browser.Gazprom Global Energy Solution’s technology aims todeliver a better overall cost/performance profile thanother systems, for low data traffic applications.Specifically, the key benefits are:The underlying radio cost structure is lowerNear real time data down to 10 secondsChoice of wide area network (Internet and GPRS)Longer ranges can be achieved and for a givenrange, reliability is betterLong battery lifeThe system can make use of low powered,unlicensed frequency bandsThe system can comply with regulations in manycountriesThe system has a full range of interfaces, fromelectrical interfaces, to internetWeb enabled management interfacesHas complete integration with GGES’s otherproducts and solutionsThese attributes are ideal forapplications such as:Monitoring and targeting applicationsPrimary meteringSecondary meteringInterface to Customer Display UnitsLink to BMS
