ZigBee chips require very little power, which means they can be operated for long periods using only a battery. However, because they send and receive data at a low rate, these chips are not right for pushing large amounts of data; rather, the technology is designed to help create wireless sensor networks for close-range remote monitoring, home control, and building automation network applications. While many applications are consumer oriented, some business security uses are foreseen.
There are a multitude of standards like Bluetooth and WiFi that address mid to high data rates for voice, PC LANs, video, etc. However, up till now there hasn’t been a wireless network standard that meets the unique needs of sensors and control devices. Sensors and controls don’t need high bandwidth but they do need low latency and very low energy consumption for long battery lives and for large device arrays.
