As a major feature of intelligent lighting , in fact, wireless control has been applied to lighting control as early as 2005, but due to various technical bottlenecks and cost constraints, it has become the mainstream of the market until now. Currently, the mainstream wireless transmission standards in the market include Zigbee, Bluetooth, and WiFi. According to industry insiders, Bluetooth has a short transmission distance and few transmission channels. WiFi consumes a lot of power and equipment costs are high. Therefore, for home lighting, Zigbee has advantages in both technology and cost. ZigBee is expected to become mainstream. specification.
What is Zigbee?
IEEE802.15.4 (Zigbee)
Zigbee is a low-power personal area network protocol based on the IEEE802.15.4 standard. The technology specified under this protocol is a short-range, low-power wireless communication technology. The name comes from the bee's splay, because bees rely on flying and "zig" to shake the wings of the "dance" to convey the position of the pollen with the companion, that is, the bee relies on this way It constitutes a communication network in the group. It is characterized by close proximity, low complexity, self-organization, low power consumption, low data rate, and low cost. It is mainly suitable for use in the fields of automatic control and remote control and can be embedded in various devices. In short, ZigBee is a cheap, low-power, short-range wireless networking communication technology.
ZigBee Technical Analysis
ZigBee technology is developed and promoted by a ZigBee Alliance, a group of companies. The ZigBee Alliance is sponsored by seven well-known international companies, Honeywell, Invensys, Mitsubishi Electric, Samsung, Motorola, Philips and Ember. In November, the alliance participated in more than 100 companies, all of which have significant influence in the industry.
ZigBee status and prospect analysis
Although ZigBee applications are more and more, and chip shipments are increasing year by year, in general, the ZigBee market is still in the initial exploration stage, and there is no real take-off. The main reason is that the applicable terminal commercial products are still in the research and development. At the stage, there are not many real listings. There are few directions and areas for typical applications, and there are many peer-to-peer applications. There are few mesh network applications that embody the advantages of ZigBee, and there is a lack of large-scale networking applications that reflect ZigBee.
