1. Introduction

With the popularization of smart terminals, the maturity of industry, technology and market, and the promotion of international brands, the Internet of Things (IoT), smart home and smart security have begun to enter people's lives. It is no longer a hot concept, but a batch of products that continue to emerge and sell well in the market.

Smart security is one of the most important market segments of smart home, and compared with other smart home applications, the demand for remote monitoring, remote alarm and smart linkage of security is more urgent. Imagine that when there is abnormal movement, gas or smoke problems at home, you can learn about the abnormal situation at home through your mobile device at the first time even if you are not at home, and take timely response strategies to reduce your property losses and protect your family.

2. Wireless technology landscape of smart home: (Wifi, Zigbee, Bluetooth)

WiFi is infrastructure:

It is generally used for wireless network technology covering a certain range (such as a building) (coverage range is about 100 meters).

The main existing problems are: high power consumption, high price, poor mobility and poor networking capability.

ZigBee is the connection method:

It is used in low-speed, low-power scenarios, such as wireless sensor networks, and is suitable for industrial control, environmental monitoring, smart home control and other fields.

The main existing problems are: difficulty in promotion (a gateway is required to connect to the network, and the comprehensive costs such as installation and debugging are high), high product costs, and uncontrollable network delays.

Bluetooth service mobile device:

There are currently more than 3 billion Bluetooth devices in the world, and the total number far exceeds the total number of Wi-Fi and ZigBee devices. The application of Bluetooth extends to many applications such as mobile phones, game consoles, headphones, notebooks, and cars. The launch of Bluetooth 4.0 has further expanded the application areas of Bluetooth.

The main existing problem: poor networking capabilities.

Current status of smart home:

Zigbee technology has been promoted in smart homes for many years, but market acceptance is very low. The biggest reasons are: 1. High cost 2. It requires routing and network connection, which makes the connection setup complicated, the installation cost high, and the promotion difficult.

3. Introduction to CSR Mesh Bluetooth Network

The launch of CSR Mesh will change the landscape of smart home wireless technology:

In February this year, CSR announced the launch of a new Bluetooth® Smart solution with disruptive technology - CSR Mesh. This solution was created by CSR, a leader in Bluetooth. It integrates Bluetooth configuration and control protocols into CSR's mature Bluetooth Smart products, such as CSR101x? and CSR8811?, and uses star network and relay technology. Each network can connect more than 65,000 nodes, and networks can also be interconnected. Ultimately, countless Bluetooth Smart devices can be interconnected or directly controlled through the same mobile phone, tablet or PC. This is the first in the industry.

David James, senior product marketing manager at CSR, demonstrated mesh control and excitedly emphasized, "Its power consumption is only one twentieth of Zigbee, and it does not require a gateway. It can be controlled by a mobile phone or tablet, which is very simple and easy to use."

The popularity of smart terminals has put Bluetooth devices in the hands of every consumer. Therefore, in terms of product promotion and popularization, Bluetooth has inherent advantages over Xigbee. Consumers do not need to change too much and can enjoy the convenience and enjoyment brought by smart homes. At the same time, unlike Zigbee, which has been used in the industrial market with limited sales, Bluetooth BLE has served the mass consumer market since its birth. The cost and technical threshold are much lower than Zigbee, which is more conducive to the popularization of products.
