As we enter 2016, the battle for the Internet of Things has intensified. In addition to the terminal manufacturers in the product function to seek new innovation, the chip factory that masters the definition of the upper layer of the product function is also in this battle, and strives to solve the problem of the Internet of Things from the "fundamental" of the product.
In the absence of a unified standard for IoT network standards, competition is fierce. Zigbee, BLE, WIFI, Homekit and Thread alliances and vendors are not far behind in the networking and power consumption areas of the Internet of Things. Among them, the Zigbee standard is the most dazzling. The natural networking and low-power features make it the first choice for most smart homes and the Internet of Things. This is even more pronounced after the release of the Zigbee 3.0 standard.
The status quo of Zigbee
According to Wikipedia, Zigbee was developed by the ZigBee Alliance, a Honeywell company. It has been in development since 1998 and was incorporated into the IEEE 802.15.4 standard specification in 2001 by the Institute of Electrical and Electronics Engineers (IEEE). Since then, ZigBee technology has gradually become One of the low-speed short-range wireless communication technologies commonly used by various industries.
Zigbee has the characteristics of low power consumption, low cost, short distance, low speed, high capacity and high security. In the low-power standby mode, two No. 5 dry batteries can support one node for 6 to 24 months, or even longer; and, by greatly simplifying the protocol (less than 1/10 of Bluetooth wifi), the communication is reduced. Controller requirements.
At the same time, ZigBee provides a three-level security mode, including no security settings, access control lists (ACLs) to prevent illegal access to data, and symmetric passwords using the Advanced Encryption Standard (AES 128) for flexible security attributes. . In line with the current growing demand for IoT security.
It is such a technology that has been well received by developers since its launch in 2001, especially in the smart home field, an important part of the Internet of Things. Zigbee is a well-deserved brother. Recently, at the wireless technology seminar hosted by the Electronic Enthusiasts Network, Zigbee China Group Chairman Su Weimin said that Zigbee is widely used in typical IoT devices such as smart lighting and smart home, and has a larger scale than other wireless connections. Leading edge.
Market share of various wireless technologies in smart homes
In the field of wireless lighting, Zigbee chips are growing rapidly and will grow substantially in the next few years, President Su stressed. Considering the importance of smart homes in the Internet of Things market, the status of smart homes in the Internet of Things cannot be ignored. However, with the iterative advancement of technologies such as WIFI HALOW, BLE MESH and Lora, and the entry of Apple and Google's two major platform giants, Zigbee's leading edge is being gradually eroded. To reverse this situation, Zigbee launched a new Zigbee3 at the beginning of the year. The .0 standard uses the method of “cross-linking†to “receive†the Internet of Things.
