What makes us increasingly inseparable from WiFi?

Now our router products are basically dual-band support, that is, 2.4 GHz and 5 GHz components. Now 802.11 AC has a three-band solution, that is to add an additional 5 GHz band on the original basis. The function of three-band WiFi is similar to that of MU-MIMO. It also improves the efficiency of connection communication and the utilization of bandwidth. If the device does not have MU-MIMO technology, the router can also communicate with two devices at the same time in its 5GHz band. In fact, its purpose is to solve the problem that when multiple routers are relaying and connecting in a family, a 5GHz band is connected to a relay router for a long time, occupying all the bandwidth of this 5GHz band. In this case, the remaining 2.4 GHz band and another 5GHz band can still work without interference. It should be pointed out that MU-MIMO support can be added to each band, that is, it has no effect on the efficiency of routers.

MU-MIMO is very helpful to improve the efficiency of WiFi. Wider 80/160MHz can increase the bandwidth. The 4x4 antenna configuration and the addition of three-band technology are good for acquiring better signals and improving the anti-jamming ability.

Besides being fast, it's also easy to use.

The technology mentioned above is to increase the capacity and speed of WiFi network, but with the advent of the Internet of Things era, WiFi routers will appear in a combination form, which means that there will not be only one router in our home, enterprise and company, and we are increasingly inseparable from WiFi. Whether it's your parents or your children, they may often encounter obstacles to setting up WiFi networks, and the connection of multiple routers, setting up relays and other tasks will make it more difficult to configure. For this phenomenon, Qualcomm Wi-Fi SON technology enables WiFi network installation to become more intelligent, secure and fully automated.

WiFi Son technology has four characteristics: self-configuration, self-management, self-repair and self-defense. In terms of self-configuration, it is actually to let mobile phones automatically find WiFi hotspots, and mobile phones will automatically pop up dialog prompt boxes to connect; self-management means that device terminals can automatically detect 2.4 GHz and 5 GHz signal strength, bandwidth occupancy and other indicators, and access to 2.4 GHz or 5 GHz according to the principle of optimal selection. If you are very close to the router, the network throughput in the 5GHz band will be relatively large, and the mobile phone will automatically select the connection. But when you are far away from the router, the quality of the 5GHz band will become very poor, and it will automatically select and convert to the 2.4 GHz band. This process is seamless, and consumers will not be aware of it.

Self-repairing refers to the situation where there are many WiFi hotspots in public places. If you connect a hotspot that can not be connected to the Internet, the system will automatically find other hotspots that can be connected to the Internet through automatic repairing. When the original hotspot resumes networking, it will automatically reconnect. Finally, self-defense means that under the Internet of Things, all kinds of devices, such as light bulbs and door locks, have the ability to link, but they can not protect their own security. WiFi Son can provide these terminals with the ability to protect and learn, such as when you go home, the light bulb opens automatically, learn and adapt to user behavior.

With WiFi Son, automatic configuration features make it easier to load and configure new terminals (including Bluetooth terminals) in WiFi networks, which include self-management features.

LTE and WiFi are smarter

LTE and WiFi are closely related, and some wireless technologies can enhance the user experience. Qualcomm's low power hot spot function and LTE and WiFi antenna sharing are interesting and practical technologies in the near future. Normally, hot data sharing between LTE and WiFi requires data exchange through wake-up processors. Low-power hot technology is the step of reducing wake-up. LTE and WiFi exchange data directly to reduce power consumption.

Antenna sharing is called Antenna sharing, which allows WiFi and LTE to share antennas. Because the antenna design is becoming more and more complex, the terminal equipment on our hands can accommodate very limited antennas. Using antenna sharing technology, when LTE does not use an antenna, WiFi can use the idle antenna.

Usually, our mobile devices now basically have 2X2 or 4X4 antenna design. If we use antenna sharing technology, we don't need to design antenna for WiFi connection, just share LTE connection antenna. Because LTE bands are partially similar to those used by WiFi, it is much easier for them to share antennas.
