Introduction to the current mainstream smart home wireless protocol
The smart home system mode is divided into wired or wireless. At present, the demand for wired at this stage is lower than that of wireless. Achieving a wireless smart home mode requires a communication protocol. So, do you know what the current mainstream smart home wireless protocols are?
Current mainstream smart home wireless protocol:
1, ZigBee
The ZigBee protocol is recognized as one of the most suitable protocols at the moment.
ZigBee's main frequency bands are 868MHz, 915MHz, 2.4G three frequency band letters, 868MHz is a commonly used frequency band in Europe, 915MHz is a commonly used frequency band in the United States, and 2.4G is a global common frequency band. The main features of ZigBee are low power consumption, self-organizing network, high reliability, high system and strong anti-interference ability. ZigBee has a transmission speed of 250Kbps and more than 65,000 theoretical nodes.
2, ZWave
ZWave is a new RF wireless communication protocol. The main frequency band is 908.42MHz US 868.42MHz Europe, ZWave is widely used in Europe. The main features of ZWave are low power consumption, self-organizing network and high reliability. There are more than 200 ZWave theoretical nodes.
Z-wave has a simple structure, low cost, and high sensitivity. Because z-wave uses single channel to transmit data, it is slightly lower than the ZigBee protocol in terms of self-healing ability and anti-interference ability.
3, RF433
The data signal can be transmitted at high speed. Because of the speed, the RF433 has a two-way communication design, and the source of the bidirectional feedback is taken from the round trip of the signal. Two-way communication is achieved when an instruction is issued to the instruction, and then back. Just like making a phone call,
4, WiFi
The most common wireless protocol in life. Adopting the domestic 2.4G free frequency band, directly connected to the Internet, mobile phone download APP, you can directly control. The main features of WiFi are extremely fast transmission speed of 54Mpbs, high reliability and poor system performance. Due to the small number of WiFi devices connected, it can not form a systematic smart home, and most of them are applied to single-purpose intelligent hardware, such as WiFi sockets, WiFi remote controllers, and the like. The most common wireless protocol in life. Adopting the domestic 2.4G free frequency band, directly connected to the Internet, mobile phone download APP, you can directly control.
5, Bluetooth
The main features of Bluetooth 5.0 are 1Mbps transmission speed, short transmission distance, high security, low power consumption and weak system. The connection of Bluetooth can only be one-to-one and the distance is about 20 meters. Most of it is used in single-purpose intelligent hardware, such as home background music, Bluetooth light bulb, smart bracelet and so on.
The above is the relevant introduction of the current mainstream smart home wireless protocol, I hope that through these introductions to help everyone understand the wireless smart home system mode.
