Energy conservation is going to be ‘the focus’ in coming days and that is getting reflected in the amount of growth in smart meter deployments. Smart meters help managing energy distribution and consumption very efficiently when compared to the conventional utility meters. Smart meter acts as a middleman that connects consumer energy management systems to utility companies. Consumers can make a conscious decision whether to use High current appliances in order to reduce their electricity bill.
One of the major advantages of going for Sub-GHz wireless communication technology is the long range. Longer the range, cheaper the deployment cost since fewer repeaters are required. SUB-GHz RF signals can travel longer distances for a given output power and receiver sensitivity. One way to increase the range is to increase the transmit power of the signal. But this comes at the cost of high power consumption. There are several ICs that provide integrated power amplifier. But the key here is the efficiency of the power amplifier. In SANDS Sub-GHz module, Microchip’s AT86RF215M SUB-GHz chip requires only 62mA to output +14 dBm in the 865 MHz frequency band.
