Smart Gas Grid Two-Way Fixed Communications Network
Smart Gas Grid Two-Way Fixed Communications Network
Worldwide recognition has developed for the real need to increases intelligence throughout the gas network using a 2–way fixed network communications solution enabling access to every end-point in near real-time. This is a "network" that can monitor events in real-time, control flow while immediately and automatically alerting the system operators of un-normative events.

Based on a fixed network 2-way unlicensed RF communication system (with 99%+ reliability), the system is an “end-to-end” platform which incorporates interoperability with a variety of smart end-point vendors and is controlled by a user friendly central software system.   

Reliable 2-way fixed network communications enables a variety of applications such as:

  • remote meter readings on demand;
  • synchronisation of meters’ real-time-clocks;
  • identification of gas leak;
  • customer access to granular consumption data via an online portal;
  • remote control of flow, and valves in near real-time;
  • pre-payment functionality including charging of the smart meters via the communications;
  • extension of meter battery lifetime by communications handshake enabling meters to revert to sleep mode when  communications have been confirmed;
  • remote firmware upgrade of network elements (meters, repeaters, concentrators) via the Meter Data Management (MDM) software;
  • tampering alerts in near real-time;
  • remotely update Time-of-Use (TOU)/step tariff tables.

 

The system gives utilities the peace of mind that the solution they deploy is already well established and proven, and will create a secure, data highway for mission critical applications like smart metering, as well as a clear path to the utility network needs of tomorrow.

Quick Specs:

  • True two-way fixed network communications with high-performance reliability, availability and scalability
  • Single concentrator (aggregator) can handle up-to 40,000 endpoint.
  • Multi-layered security (from endpoint to user interface).
  • Unlicensed frequency operating in 850-920Mhz
  • Protocol: RF – Modbus;
  • Bandwidth: 52kbs both sides;
  • Communication distance 1.5 km line of sight (LOS) 300m built up (depending on local conditions) from meter before requiring a repeater;   
  • Star Network - Certain meters can be configured to perform as repeaters. The repeaters are mesh.   It is a learning system.
