Zigbee, WiFi and 433MHz wireless radiofrequency technology all belong near field communication (NFC), and all use the ISM unlicensed band, but they differ from one another.
The characteristics of ZigBee are low-power consumption, high reliability, strong anti-interference, arrange net easily, can easily network coverage be extended to decades of times by wireless repeater, therefore the occasion from little space to large space, from simple space environment to complex space environment can be used.But than the WiFi technology, Zigbee is the application that is positioned low transmission rate, so Zigbee obviously is not suitable for the occasions such as high speed Internet access, large file download.Wireless ordering for catering industry is used, and because in general its volume of transmitted data is not very large, so ZigBee technology is to be fit to very much this application.
The characteristics of WiFi are that message transmission rate is high, and support " always online " function.For some application or occasion, these functions may be useful.But it should be noted that the negative effect that these functions are brought is increase and reliability and the reduction of performance of power consumption.Contrast is therewith, and the normal mode of operation of Zigbee and 433Hhz technology is only just can set up Radio Link in the moment that data transmit-receive is arranged, and has therefore greatly reduced the interference to miscellaneous equipment in network, has also reduced the power consumption of equipment itself simultaneously.Certainly, Zigbee also can become to be similar to from the angle design of application layer the pattern of " always online " with the 433MHz technology, comes the compromise between practical function, power consumption and reliability by rational " refresh time interval " parameter is set.In addition, than Zigbee and extremely short sleep awakening time of 433MHz equipment (~ 30ms), the sleep awakening time of WiFi equipment generally needs 3 ~ 5 seconds.
433MHz utilization 433MHz radio band, therefore than WiFi and Zigbee, the significant advantage of 433MHz be the penetrability of wireless signal strong, can propagate fartherly.But its shortcoming is also clearly, is exactly that its message transmission rate only has 9600bps, is far smaller than the data rate of WiFi and Zigbee, so the 433Mhz technology generally is only applicable to volume of transmitted data less application scenario.From the angle of communication reliability, the 433Mhz technology is the same with WiFi, only supports the topological structure of Star Network, realizes the expansion in network coverage space by the mode of many base stations, so the reliability and stability of its wireless telecommunications also are inferior to ZigBee technology.In addition, be different from the encryption function that adopts in Zigbee and WiFi technology, general employing data transparent transmission agreement in the 433Mhz network, so its network security reliability is also relatively poor.
