Why Zigbee Consumes Low Power

Zigbee is a wireless technology developed as an open global standard to address the unique needs of low cost low power wireless iot networks.

Why zigbee consumes low power. On a uniformly scaled application the power consumption of ble zigbee and wifi were respectively 72 microwatts 90 microwatts and 0 2 watt. Why zigbee is ideal for communication in home networks. For all measured sleep intervals ble achieved lower power consumption 10 1 ua at 120 s interval compared with zigbee 15 7 ua and ant 28 2 ua. The difference being while bluetooth and wi fi are high data rate communications standard supporting.

The power efficiency figures speak out in favour of wifi due to its high data transfer rate. Atmel has developed a low power zigbee transceiver with a static consumption of just 20 na a reduction of five over previous devices coupled with a listening receive mode of just 6 ma and 14 5 ma transmit power at 3 dbm. This comes from using a 1 8 v supply and a 16 mhz 8 bit avr controller. Power consumption differences can be attributed to the time taken for a node to connect to the hub after waking up and the use of sleep between individual rf packets.

Established in 2002 our wide ranging global membership collaborates to create and evolve universal open standards for the products transforming the way we live work and play. These can talk up to a maximum range of 300 meters with a clear line of sight which works out to between 75 100 meters indoors. The zigbee alliance is the foundation and future of the iot. Zigbee is an ieee 802 15 4 based specification for a suite of high level communication protocols used to create personal area networks with small low power digital radios such as for home automation medical device data collection and other low power low bandwidth needs designed for small scale projects which need wireless connection hence zigbee is a low power low data rate and close.

Zigbee pro and zigbee remote control rf4ce among other available zigbee profiles are based on the ieee802 15 4 protocol which is an industry standard wireless networking technology operating at 2 4ghz targeting applications that require relatively infrequent data exchanges at low data rates over a restricted area and within a 100m range. What s so good about zigbee. The zigbee standard operates on the ieee 802 15 4 physical radio specification and operates in unlicensed bands including 2 4 ghz 900 mhz and 868 mhz. 75 nj bit 360 nj bit 5 25 nj bit.

Zigbee uses the ieee s 802 15 4 personal area network standard to communicate with other zigbee devices. Reducing the power consumption of the wireless transceiver is a key objective. It is a short range communication standard like bluetooth and wi fi covering range of 10 to 100 meters. Zigbee is a ieee 802 15 4 based low power low data rate supporting wireless networking standard which is basically used for two way communication between sensors and control system.
