WIFI, ZigBee and Bluetooth, which is the best solution for smart home?

With the progress of science and technology, smart home has gradually entered the family life of ordinary residents, which will also be the future trend of life style. In the current smart home equipment market, it can be said that it is rich and colorful. The networking modes of various devices are different. They also have their own advantages in cost, power consumption, distance and other characteristics. Of course, the different networking modes also directly affect the different control technologies. At present, the widely known networking methods include wifi, Zigbee, Bluetooth and so on.

WiFi Networking

WiFi technology is currently the fastest transmission of wireless technology, in the current life of high popularity, so the current WiFi technology is very suitable for the smart home field. The disadvantage is poor security, weak stability, high power consumption, limited connectable devices, that is to say, WiFi has great limitations, which limits the development.

Igbee networking

At present, the technology of ZigBee is controversial. Firstly, the overview of Zigbee technology is introduced. ZigBee is a kind of two-way wireless communication technology with short distance, low complexity, low power consumption and low cost. But in terms of market popularity, ZigBee is far less than Bluetooth and Wifi. Because of the complexity of ZigBee protocol and the low transmission rate, it has not been popularized, but its ad hoc network characteristics make it occupy a place in the market.

Bluetooth networking

Bluetooth (Bluetooth) is a radio technology that supports short-distance communication between devices. Bluetooth system network uses Bluetooth module as the node and can be connected wirelessly without establishing base station. The transmission speed of the new version of Bluetooth 5.0 is 2 Mbps, twice that of the previous version of 4.2 LE. Another important improvement is that its effective distance is 4 times that of the previous version. At the same time, Bluetooth 5.0 also supports indoor positioning and navigation functions. Used as indoor navigation beacon or similar positioning equipment. It can be said that Bluetooth 5.0 has done a lot of bottom optimization for the Internet of Things in order to serve smart home with lower power consumption and higher performance.

As we all know, WiFi is characterized by its wide range, fast speed, but high power consumption. As for ZigBee, I believe that many people are the first to come into contact with the name. Its advantages are low power consumption, slow speed, incompatibility, and the most lethal point is that the popularity of the devices it carries is extremely low; while Bluetooth Technology is committed to working on it. In a specific space, all the devices supporting this technology are connected to transmit data. Its characteristics of extremely low power consumption, low cost, stable security, open interface and so on are very in line with the technical requirements of the Internet of Things.

From the Internet, to the mobile Internet, and then to the Internet of Things, the way people access the Internet is changing constantly. The Internet of Things represented by smart home is moving from concept to product, with huge market prospects. It will also completely change the mode of the traditional Internet era. Today, for smart hardware, mobility and endurance problems have created bottlenecks in user experience. In fact, Bluetooth technology is the most suitable solution for the Internet of Things.

With the development of science and technology, our life has undergone tremendous changes. The types and functions of smart home continue to expand. Will Bluetooth technology, as a connecting smart product, bring us further surprises in the future? Let's wait and see.
