Qualcomm dual-channel WiFi technology to help you solve the problem of poor home WiFi signal

Since United Technologies acquired the avionics and interiors transaction for $23 billion, United Technologies has become one of the world's largest suppliers of avionics components. In order to solve the situation that the large number of charging piles in the waiting room are in short supply, the airline has adopted a Qualcomm dual-channel WiFi technology, which not only solves the problem of too large coverage, but also improves the capacity and capacity of the public WiFi network to allow passengers. High-speed WiFi is available in the lounge, in the washroom or in the store.

Many people may have doubts, the airport area is so large, and there are so many connected terminal devices. Why does public WiFi still guarantee such good coverage and network speed performance? And our home area is much smaller than the airport, why is WiFi coverage still not good? In addition to MU-MIMO technology to alleviate congestion, AC+AP coverage technology is also needed.

Home WiFi signal is poor, "it" can help you

Most of the WiFi networks used in airports today use AC+AP coverage, such as an AC (wireless controller) + multiple APs (transceive and receive signals). Of course, some traditional devices such as routers and switches need to be used in the network. Because of the high power consumption, large equipment, and large size of this coverage scheme, it is obviously not applicable to the general home environment.

For home use scenarios, in order to make WiFi coverage better, we might think of using multiple routers for bridging or using power cats to enhance the signal. But in fact, they all have many shortcomings. For example, after multi-route bridging, the network speed will drop, and the network will be unstable due to the increase of equipment. Power cats have requirements for the quality of the wires. Too bad wires, air-switched units, and lightning-proof filtering plugs cannot be used, and the application conditions are relatively harsh.

Is there no one-step solution? Perhaps with Qualcomm's dual-channel WiFi technology, a router can solve the coverage problem perfectly.

Before saying how amazing the dual-channel WiFi is, we have to popularize what is called dual-channel WiFi. First of all, the traditional single-channel WiFi has only one antenna at the transmitting end and the receiving end, that is, the data transmission and reception can only rely on one channel.

Assuming that the data is a truck, single-lane 1*1 WiFi is a two-way lane. When multiple trucks are transported back and forth, it is easy to “catch the car”. At the same time, some “roadblocks” (other connected devices, walls, etc.) will Interfere with it, causing "WiFi signal blind zone".

The dual-channel (2*2 WiFi) adds one more channel, that is, there are two two-way lanes, so that more drivers can start at the same time, which can greatly increase the data transmission rate and have greater coverage. The range can solve the signal blind zone.

In the simulation test, Qualcomm dual-channel WiFi theoretical data throughput is twice that of single-channel WiFi. If we have a router that supports Qualcomm's two-channel WiFi technology in our living room, the corners of the room, bathroom, kitchen, etc. can be well covered, so we can say goodbye to unstable multi-router bridges or many conditions. Power cat. In addition, Qualcomm dual-channel WiFi can reduce the power consumption of the terminal by up to 30%, effectively improving the battery life of the smartphone.

After using Qualcomm's dual-channel WiFi technology, your mobile phone and tablet will be more durable, and you can load HD video in the corner of the room and play the "king" at low time!

At present, there are many models supporting Qualcomm dual-channel WiFi technology, such as OPPO R11, vivo X20, Xiaomi 6, Xiaomi MIX2, One Plus 5 and so on. With the popularization of Qualcomm's dual-channel technology and the rising market share of Snapdragon's mobile platform, more and more users will enjoy the "pleasure" brought by dual-channel WiFi in the future.
