Several misconceptions about ZigBee smart home

Baidu Encyclopedia's explanation of Zigbee is: "ZigBee is a low-power LAN protocol based on the IEEE802.15.4 standard, which is a short-range and low-power wireless communication technology. The name (also known as the Purple Bee Protocol) comes from the bee's figure-of-eight dance, which relies on flying and "ziging" to communicate the location of pollen to its companions, which means that bees rely on this method to form a communication network in the colony. ”

ZigBee has always given the impression of advanced technology, smart home-first wireless communication technology, which has to do with the media hype when ZigBee was first introduced. It is undeniable that people's beautiful yearning for smart home will never stop, before the advent of ZigBee, the industry lacks reasonable smart home communication technology, and the emergence of ZigBee technology has once again ignited people's good wishes for smart home. In this context, people have great expectations for ZigBee technology, hoping that it can solve the communication between smart home devices, which causes people to have the impression that ZigBee technology is "advanced", and it is undeniable that ZigBee has its advantages such as: strong anti-interference, good confidentiality, fast transmission, strong scalability, etc. But is it really that? Actually, every technology has its limitations, and ZigBee is no exception, so let's talk about a few misconceptions people have about ZigBee.

Is the cost really low?

At present, the cost of TI's CC2430, CC2530 and Freescale's MC1319X and MC1322X series is about 2~3 US dollars, and considering other peripheral devices and related 2.4G RF devices, the BOM cost is difficult to be less than 10 US dollars.
