Zigbee vs WiFi
Most common diffrences between Zigbee and WiFi is given below.
Parameter | Zigbee | WiFi |
---|
1)IEEE standard | IEEE 802.15.4 | IEEE 802.11b |
2)Frequency band | 2.4GHz | 2.4GHz |
3)Maximum number of end devices | 65535(therotically). Practially it depends on how you configure the Cordinator. | It depends on network type. If network is class C with sub net mask 255.255.255.0 then maximum 254 devices can connect. |
4)Current consumption | Very low [25-35 mA (Tx mode) and 3 HA (Standby mode)] | Very low but greater than Zigbee [400 mA (Tx mode) and 20 mA (Standby mode)] |
5)Range | up to 30 m (therotically - for free space communication) | 75 to 90 m |
6)Network join time | 30 ms typically | variable, 1 sec typically |
7)Data rate | 250 Kbps | 11 Mbps |
8)Bandwidth | 3MHz | 22Mhz |
9)Total number of channels | 16 | 13 |
