How far is ZigBee technology from us?

"the biggest challenge for ZigBee's massive application is software," emmanuels, global business director of TI's low-power RF business, broke through the bottleneck of industrialized preparation. Ambuis recently admitted to the world of electronic engineering. Most people look at the "zigzag dance" of bees from an appreciative perspective. However, zigzag is still the communication mode for the survival and development of bees. ZigBee, a short-range wireless technology named after the "8-word dance" of bees, is quietly entering our lives with its advantages of low power consumption and low cost

however, according to the 2016 report on the development status and trends of green packaging in China's express industry, ZigBee standards have not been applied on a large scale as the advocates hoped since they were first determined in 2004. But many manufacturers are still betting on it

China: smart home was the first to set sail

zigbee failed to rapidly popularize as expected due to various reasons. First, most terminal products and applications are in the R & D stage, and few are really listed; Second, there are many point to multipoint applications, and there are few shape networks that reflect ZigBee's advantages; Third, there are few applications based on ZigBee standard protocol, and many customers use private protocols based on the bottom layer of 802.15.4; Fourth, there are many potential applications, but the market lacks a clear direction

it is true that the applications of ZigBee can be listed, such as home and building automation, industrial monitoring, equipment tracking, low-power wireless sensor network, set-top box and remote control, automatic meter reading and medical treatment. Taking the meter reading system as an example, each family has different meters, including electricity meters, water meters and gas meters. Different meters have corresponding protocol stacks, so different meters are required to communicate with each other for energy management. The same is true for smart home. If there is no standard protocol stack between the light control and the probe, communication will be difficult. The standard protocol stack based on ZigBee can easily solve this problem. But the real feature application has not yet appeared

"unlike the first application in AMI (advanced measurement facilities) in the United States, ZigBee will be the first to be applied to smart home systems in Europe and China," sambuis predicted

imagine that the troubles of five or six remote controls in your home seem to be solved at once, because the intelligent remote control will become the remote control for the lights, TVs, DVDs, stereos or air conditioners you want. When you pick it up, the DVD will automatically pause, the TV will become silent, and the lights will automatically control the brightness

what about ZigBee in the hot field? Sambuis' answer is very intriguing. He said ZigBee would not be used in the short term. Of course, Bluetooth technology, which is widely used in, also has its disadvantages: taking home lighting as an example, this application has very strict requirements for power consumption, and Bluetooth power consumption is not low. At this time, ZigBee's low-power technology comes in great use. In the low power standby mode, two No. 5 dry batteries can support one node to work for 6 ~ 24 months, or even longer. In contrast, Bluetooth can work for weeks and WiFi can work for hours

"of course, the positioning of valuable medical instruments is one of the potential applications in the future," sambuis said. In addition to tensile, compression, zigzag, peeling, shearing and other performance tests on various materials, this positioning function is also applied to parking lots in the United States. There are many cars in car rental companies in the United States. It is basically difficult to find thin plastic pipes in parking lots, so they put ZigBee chips in each car, and then set up a Zigbee network in the parking lot, This makes it easy for customers to find the car they need

the growing ZigBee technology is a group of technical standards for group, security and application software based on the 802.15.4 Wireless Standard approved by IEEE. Unlike other wireless standards such as 802.11 or 802.16, ZigBee and 802.15.4 carry limited data traffic at a maximum transmission rate of 250kbps

ieee802.15.4 and ZigBee share the same roles as IEEE802.11 and Wi Fi. ZigBee is built on the 802.15.4 standard, which determines the application outline that can be shared among different manufacturers. 802.15.4 only defines the entity layer and the media access layer, which is not enough to ensure that different devices can talk. Therefore, ZigBee alliance is established. Therefore, 802.15.4 does not necessarily use ZigBee protocol stack. Conversely, if ZigBee protocol stack is used, 802.15.4 must be used

however, whether it is the 802.15.4 dedicated protocol stack or the ZigBee standard protocol stack, the hardware is the same hardware, so the global analysis data put the two together. The compound annual growth rate of 63% from 2005 to 2012 is also showing the great potential of ZigBee. It can be imagined that ZigBee will quietly invade our lives in the next three to five years

the third way to accelerate design

Ti launched its latest product on April 24, 2008, hoping to "help customers shoulder some burdens" in the years of rapid development of ZigBee in the future, and do a good job in the content of the agreement stack, so as to accelerate the development of ZigBee market, Cc2480 is the first generation of ZigBee compliant network processors in the z-accel (acceleration) product series that conforms to this trend
