Application Note
WiFi is generally considered as quite power-hungry. This is not an inherent inefficiency of the IEEE 802.11 protocol but rather the way it is implemented and deployed for conventional applications. Indeed, with an energy consumption of 1 to 17 joules per MBytes[01] of data transferred for conventional high-power Wi-Fi equipment, even very inefficient implementations can provide 1 MByte of data transmission per day with a single set of "AA" batteries over a duration of four years.…
