Speaking of the history of smart home development, we have to mention ZigBee technology, ZigBee is based on the IEEE802.15.4 standard, using the frequency band 800Mhz/900Mhz/2.4G, because of the low cost and its unique jump transmission characteristics are industrially controlled. It is popular among industrial control equipment manufacturers. Since its introduction in 2001, due to its low power consumption and long transmission distance, he has been widely used in the connection of objects and wireless communications. We can think that the birth of ZigBee technology is the bud of the Internet of Things, and ZigBee is in the field of industrial control. The application has been widely used since the birth of this technology. People have begun to realize that simple human wired connections can no longer meet our actual needs. We need more wireless connections and character interactions in practical scenarios. We can think of this as the meta era of the Internet of Things.

 

In 2013, Qualcomm launched the industry's first WIFI low-power SOC, completely breaking people's understanding of the Internet of Things. WIFI is based on the 802.11 protocol and works in the 2.4G/5G band because of its WAN access capability. To make people's Internet of Things technology shine, and based on China's sound Internet technology development capabilities, people's awareness of the Internet and cloud concepts, intelligent terminals, we can more easily connect to all things, I think this is the Internet of Things 1 In the era of .0, the significance brought by WIFI connection is not only the change of connection mode, but also the change of thinking mode. The connection becomes a physical communication mode, and the Internet becomes a spiritual support.

 

In the past two years, the Internet of Things has sprouted from germination to sputum, and it has been widely recognized by everyone. The Internet of Things WIFI connection has played a leading role, bringing hope to equipment manufacturers. We are eager to welcome this change, but with manufacturing In this in-depth exploration of this direction, there is a problem that manufacturers have to face again, how to solve the power consumption problem, it is true that Qualcomm has optimized the power consumption of this SOC for the Internet of Things market, but because of the characteristics of WIFI, Power consumption does not have much advantage in traditional low-consumption technologies, such as Zigbee and Bluetooth, and people are starting to re-examine low-power physical connections.
