The difference between WiFi and ZigBee

Comparison and advantages of ZigBee-WiFi :
Hardware memory requirements contrast:


WiFi:1MB+;   ZigBee hardware demand is low.
Battery powered power on sustainable time:

ZigBee:100~1000 days;

WiFi:1~5 days;   ZigBee power consumption is low.
Transmission distance contrast (general use, no high-power antenna launcher):


WiFi:1~100M;   ZigBee long transmission distance.
ZigBee disadvantage:
Network bandwidth contrast: ZigBee:20~250KB/s;

WiFi:11000KB/s;   ZigBee bandwidth is low; transmission is slow.

Same point:
1. They Both are short-range wireless communication technologies;
2. all using the 2.4GHz band;
3. all using DSSS technology;
1. the transmission speed is different.
ZigBee transmission is not high (<250Kbps), but the power consumption is very low, the use of battery power, generally can use more than 3 months;
WiFi is commonly referred to as wireless LAN, with high speed (11Mbps), large power consumption, and general external power supply;
2. different applications.
ZigBee is used in low rate, low power applications, such as wireless sensor networks, for industrial control, environmental monitoring, smart home control, and other fields.
WiFi is generally used to cover a certain range (such as 1 buildings) wireless network technology (coverage of about 100 meters). The form is our usual wireless router. In a building is located 1 wireless router, laptop computer building (with wireless LAN), can be the basic wireless Internet access.
