"Meter reading is the backbone of the home water and gas billing system. If meters are read incorrectly or not read at all, it will cause a chain reaction of added events that add unnecessary expense and create customer dissatisfaction. Additionally, it has been well established that one of the main reasons for the EU negative balance in the supply and consumption of gas are faults in measurements. Consortium SMEs have identified a clear need to develop a metropolitan gas/water metering system based on wire-less technology to send gas and water supplies readings to their control centre. The system will require no maintenance (battery powered sensors with life-time about 10-15 years) and will provide authenticable and secure data transmission. Timely and accurate recording of the consumption of gas, water and electricity is important as it will also help in identifying any leakages through the analysis of the actual quantity supplied and recorded by the meters. The commercial objective is to develop an ultra low power-consumption, battery-powered, wireless, cost effective and self organizing sensor network for maintenance-free automatic home meter reading applications. This network will be form by smart sensors which will include gas or water counter, logging consumption, outage detection, real-time clock and 2-way communications for remote control (i.e. switch on/switch off) and will support a huge number of sensors (+100)."
