In this age of technology, the number of connected devices in homes has soared in recent years. Consumers pay more attention than ever to Internet of things devices, such as home automation ,4 K / HD video streaming and online games, which in turn tripled the amount of data transmitted over the Internet. Therefore, your next router needs to be fully considered. Next, RenhotecIC engineers will describe in detail how wireless routers, networks, Wi-Fi6 merge.


　　Wi-Fi technology: IEEE 802.11 is the technical generation that defines international Wi-Fi standards. "802.11 n/ac/ax" represents specific standards ac 802.11, Also known as Wi-Fi 5. As 802.11 ax emerged, Commonly known as Wi -Fi 6, throughput is significantly higher. Wi-Fi 5(11ac –160MHz) can achieve a theoretical maximum velocity of 6.9 Gbps, The Wi-Fi 6(11ax-160 MHz) can reach 9.6 Gbps.. The Another key aspect that can not be ignored is the frequency band, Since Wi-Fi 5 work in five GHz, The Wi-Fi 6 supports 2.4 GHz、5GHz and 6 GHz bands.

　　.   What does "frequency band" mean? Single frequency routers have become history. The moment is about dual / three frequency routers. The dual frequency means that the router uses two frequencies of the spectrum to transmit packets, that is ,2.4 GHz and 5 GHz. The three-frequency router uses 2.4 GHz、5GHz and 6 Ghz frequency bands to support the device to select the network using frequency band control algorithm. By balancing the load of each frequency band in the three frequency bands, the congestion of the network is reduced.

　　For more technology-savvy users, it is worth studying functional availability and buying their own devices. Additional considerations for selecting routers include multi-core processors and WPA3 encryption for security reasons. Mesh network: given that we have a lot of people adapting to remote work and virtual learning this year, the number of concurrent users and devices has increased. Previously, the original throughput of home routers was a key value, but now the network elasticity and coverage of edges are equally important. Depending on the home topology, there may be some dead points. a mesh network should be used to maximize Wi-Fi coverage in areas where speed can be increased.


　　The node or commercial term is called pods Wi-Fi extender, which is strategically placed in parallel to the main center, which is connected to the broadband gateway through Ethernet cable to form a network to achieve better coverage. By rebroadcasting the packets, this topology makes the switch perfect and makes the pods a virtual access point, thus making the dead point "undead ". Typical routers can cover 2500 square feet. However, mesh networks can double coverage to a maximum of 5000 square feet, depending on the number of pod (usually 2 to 3).

　　By means of the pillar of artificial intelligence, pods can choose the fastest route in the network and optimize the bandwidth according to the needs of the equipment to provide help. For example, IoT devices will use less bandwidth than laptops. If nodes are synchronized, they can be easily managed through applications on smartphones. The selling point of these small pods is easy to use and plug and play installation, providing seamless Wi-Fi coverage.

　　Transition to Wi-Fi 6/6E：Wi-Fi 6 use 8 x8MU-MIMO、OFDMA、 extended range and basic service set (BSS) coloring and other key functions to achieve better spatial reuse. During Wi-Fi 6, network congestion is reduced to improve capacity, performance and power consumption. other considerations are target wake-up time (TWT) to achieve better power management. WPA3 enhances security ;1024 QAM improves throughput.


　　With the proliferation of Wi-Fi 6E infrastructure, seeds will be injected into six GHz of ecosystems. Client devices will also benefit from higher energy efficiency, less interference, and lower latency and jitter to provide a better user experience in multiple applications and environments.
