Recently Xemex has finalized the development of its 169 MHz. product portfolio, suitable for long-range remote reading. The performance of radio in areas obstructed by objects, walls, floors, buildings and vegetation is determined by the ability of the radio signal to penetrate through, to bend around and to reflect from obstacles. In this type of environ- ment, the performance of higher frequencies is worse than the lower frequencies, with reliable distances dropping even faster.
Our 169 MHz. product portfolio consist of the following products:
XM1000 is an Ethernet-based modular data platform that delivers processing power, security and device connectivity for smart metering applications. Combined with flexible hardware extensions and automatic software and configuration provisioning, the unit fits perfect into smart metering applications. The unit supports the industry-standard protocols DLMS- COSEM and M-bus EN 13757 1-4 and a selection of plug-in modules covers a wide range of back-haul links e.g. 2G-3G-4G-LTE450. XM3000, XM3100, XM3200 communicates to the unit over 169Mhz radio; data collection intervals are programmable to any value, but vary in general from 15 minute intervals to daily reads; management of the meter readings is in accordance with the grid operator’s metering requirements. XM1000 manages up to 1024 slave units.
XM3000-XM3100 are battery operated data concentrators designed for low power consumption to achieve a working life time of 15 years; both units support the industry- standard M-bus EN 13757 1-4. The XM3000 collects data from 868MHz M-bus mode C/T compliant meters (water, gas, electricity and heat meters) and the XM3100 reads data from wired M-bus meters. The bundled data is converted into a 169MHz M-bus N-mode compliant radio signal that is picked up by the XM1000 base station data collector or picked up by the XM3200 radio repeater and retransmitted to the XM1000. XM3000 is able to support up to 32 meters.
XM3200 is a battery operated radio repeater designed for low power consumption to achieve a working life time of 15 years; the unit supports the industry-standard M-bus EN 13757 1-4. The unit picks up the radio signal coming from the XM3000 and XM31000 units, amplifies it and rebroadcasts the boosted signal for being picked up by the XM1000 base station data collector. The XM3200 effectively extends the coverage range of the radio network – reaching far corners of the building. On average, the extended coverage is about 3 floors in upward and downward direction.
XM2000 is a mains powered separate unit that in accordance with the local smart metering requirement, collects and stores data from multi-fuel metering devices and sensors. The unit supports the industry-standard protocols DLMS-COSEM and M-bus EN 13757 1-4. Integration of the M-bus 868 C-T-mode and the 169 N-mode into the unit facilitates greatly the installation handling. The unit provides an option for remote control of the reconnect / disconnects functionality in electricity, gas and / or water meters with breaker / valve. Access to the unit is username and password protected; different High Level Security authorization levels are available. A customer data port allows the end-user to access its energy consumption data in real-time.
XM2100 The unit provides TCP/IP communication over 169MHz between E350 meters and the central system. The unit supports the industry-standard protocols DLMS-COSEM and M- Bus EN13757 1-4. Integration of both 868-169 M-bus wireless into the unit facilitates greatly the installation handling. The unit provides an option for remote control of the reconnect / disconnects functionality in electricity meters with breaker. An extra output relay on the module facilitates calendar based switching of 3th party devices (e.g. boiler). The unit is equipped with a maintenance port that may be used by the operator for data retrieval. Access to the unit is username and password protected; different High Level Security authorization levels are available. A customer data port allows the end-user to access its energy consumption data in real-time.
