I would like to know how many smart homes in China use Zigbee technology for wireless transmission.

Now Zigbee technology is still a good method in the field of smart home, and wireless is now the trend of smart home development.

In the past, the integrated wiring was not only cumbersome, but also the installation process was very slow.

Using Zigbee does not require extensive wiring.

Using American Control4 and Zigbee is a good match.

Zhengzhou has the largest and most comprehensive intelligent experience hall in the central region.

The address is 200 meters south of Jinshui East Road and Xinyi Road, 0371-66518699

At present, there are still a few wood, and the advantages of Zigbee have not yet been reflected. Because although Zigbee is a quasi-standard, it is rarely done according to this standard. It's still in a state of being separated.

Now it is recommended that you consider using the commonly used wireless transmission method, which is cheap, controllable and flexible. For example, Guangzhou Zhuoju's smart products.

This technology seems to be immature, I have consulted several companies before, there is a problem with the stability of the model room, I visited the Haolaiwu smart home experience hall in Beijing, they use RFID433 technology, I saw them operate in person, it is very powerful, I have to say that the smart home is really good, very convenient.

Zigbee has more than 20 chips and only 2-3 chips at 433MHz! The development trend is definitely zigbee and the like, not necessarily the zigbee mainstream, accidentally we Chinese research a magbee and the like

The technical parameters of the wifi solution and the zigbee solution and the radio frequency can be clearly seen in the above figure, and I will talk about the difference between the two in detail.

Let's talk about the difference: Zigbee can be understood as the most basic single-chip microcomputer + advanced wireless communication protocol. The wireless communication protocol is.

It has the advantage of self-organizing networking, with a maximum number of network nodes up to 65,000, which is very conducive to environmental surveys and other work, such as airplanes flying over a forest, scattering tens of thousands of nodes from the sky, and then you can return to the computer to observe the data. Zigbee is proposed for sensors with low data volume, so there are many possible applications of Zigbee in industry; In the smart home, some people have also proposed many possible applications, such as smart xx, that is, to connect several electrical appliances using Zigbee wireless network, so that the electrical appliances have the ability to perceive the environment, so as to take corresponding measures in different situations. At present, Zigbee is also the mainstream wireless smart home technology solution in China, and domestic Xiaomi, Haier, and Oribo are all using Zigbee solutions.

WiFi is proposed for wireless access networks, this alliance has become a household name, and many electronic devices in daily life are marked with the word WiFi. WiFi is a consortium of high-speed, high-stability radio access network solutions, and the wireless communication protocol is. Its main problem is wireless access, which is different from Zigbee in that its requirements are high speed and large capacity; WiFi does not have the ability to organize the network, so it needs to be set manually.

To put it simply, the two applications are different, and generally Zigbee is used for ad hoc networks and automatic control. Whereas, WiFi is used in human-controlled wireless access networks.

There are pros and cons to each other, without wifi and a dedicated zigbee gateway, you can't command zigbee devices (except for devices that support wifi and zigbee themselves), especially most smart homes not only rely on wifi, but also rely on the internet to work.

In places where WiFi can't be expanded, or there are too many WiFi devices at home, in order to reduce the burden on the router, optimize the network environment, or reduce the power consumption of the device, then the full-featured Zigbee is still good.

Why do you say full-featured? Because Zigbee itself supports cellular networking, each one is to extend the signal to the next device, but at present, due to cost reasons, most of the Zigbee I have seen in China do not support cellular networking, so I can only take care of myself.

On the other hand, Zigbee also works in the frequency band, although it is only nearby, and theoretically does not conflict with it, but it is often seen that some users say that there is a conflict phenomenon.

1. Low power consumption and low power consumption. Zigbee technology enables connectivity through smart modules, but it doesn't require wired devices to be charged for long standby periods of time. The power of ordinary button or alkaline batteries can ensure that it can operate continuously for more than 3 months.

As a result, the sensor hardware of Zigbee technology is flexible to use and install.

2. Connect more devices. The number of wireless connection devices based on wifi technology is at most about 15,Similar to smart sockets、Smart lights、Smart switches、Smart door magnetsThese small smart devices have reached the upper limit,If you connect to smart refrigerators、Smart TV will exceed the load,And 10Trillion network bandwidth is also very chicken。 Zigbee technology can easily connect more than 30 smart devices.

3. High accuracy. Zigbee smart home wireless communication technology has high accuracy and can complete high-end commercial projects.

4. High security. Zigbee smart home wireless communication technology will not be as easy to break through as WiFi technology, it is encrypted through 128BitAES mode, which is more secure than SSID's WiFi encryption method, bringing more protection to the smart home system.

5. Multiple interactive link mode. Zigbee smart home wireless communication technology transmits within the channel through the mesh structure of the ad hoc network, so that the communication can be established not only between the remote control terminal and the device, but also between different devices, which is more advanced than the one-way channel of WiFi.

Subject, I'll come to you.

Cause. First, most of the domestic smart home manufacturers are buying Zigbee communication protocol, and then integrating a bunch of third-party products to make their own smart home products.

Reason two, the zigbee communication protocol itself has a variety of advantages, strong stability, wide coverage, support for expansion, applicable to many types of customer groups, and a very important, the domestic subject of the so-called well-known enterprises themselves do not have the strength of R & D innovation, and the communication protocol is the core of smart home products, naturally need to interact well.

Let's talk about something fresh.

Because of the above content, the homogenization of our domestic smart home industry is seriously competitive, but fortunately, there is no shortage of companies with technological innovation strength, the traditional smart home can not achieve most of the compatibility with the customer's home appliances, and there are requirements for specific brands, so it is necessary to consider additional networking, this phenomenon still exists, so this is one of the reasons why the traditional smart home has not developed.

Now at the end of 2015, there are no brands on the market, no models, ohh smart home products that are perfectly compatible with the existing old household appliances in the customer's home, and can be installed and used without barrier-free installation without destroying the decoration, and you can realize your idea by sending a message directly with WeChat, ** close to the people, and most importantly, the smart home communication protocol they use is independently developed, and the patent is obtained.
