Feature: 1. AC dual frequency WiFi signal, with many 2.4GHz devices and large interference of wireless signal; 5GHz devices are few, pure channel interference is small, and transmission speed is fast; AC23 supports 802.11ac WAVE2 technology, with dual frequency concurrent rate up to 2033Mbps, faster than AC1900; 5GHz frequency band up to 1733mbps, meeting 4K video, live online, 3D games and other high bandwidth applications. 2. 5GHz band 4-send 4-receive, more transmission channels, faster speed: 5GHz frequency band supports 4-way wireless transmission, with more transmission channels and faster speed compared with 3-way transmission and 3-way reception (such as AC1900) on the market; it also supports 4-way 5GHz WiFi signal superposition, effectively improving WiFi coverage. 3. Wi Fi performance improved by 1 / 3, and many people still surf the Internet smoothly: It supports WAVE2 4X4MU-MIMO technology, and the router can communicate with multiple devices at the same time. Compared with 3x3 MU-MIMO WiFi, the performance can be improved by 1 / 3, and the Internet access for multiple people is still smooth. 4. The main chip has a built-in signal enhancement module: The main chip has a built-in signal enhancement module. Both 2.4GHz and 5GHz use wireless signal amplifiers. WiFi has a stronger ability to penetrate the wall and transmit further. Even in the corner of the home, you can see films. 5. Seven 6dbi enhanced antennas cover 130 square meters and penetrate three walls: The design adopts 7pcs 6dbi high gain omnidirectional antennas. Compared with the ordinary 6pcs 5dBi dual frequency routers, the coverage is increased by 20%, which can meet the coverage of 130 square meters of large houses. After three walls are worn, the Internet can also be accessed normally. 6. Support optical fiber access within 1000MB: Meet the needs of optical fiber upgrading in the next 2-3 years. The full Gigabit port design is adopted to meet the fiber access within 1000mb (100MB / 200MB / 300MB / 500MB, etc.) and give full play to the advantages of high-speed bandwidth within 1000MB. 7. Three chip architecture, more stable multi-core drive: Using three chip architecture, with 1GHz main processor, 500MHz coprocessor and Ethernet data processor, multi-core drive, compared with single chip architecture, more material, faster and more stable processing speed. 8. IPv6 support, shorter delay and smoother game: The traditional IPv4 protocol router needs to go through address conversion to access the Internet; IPv6 protocol has a large amount of IP address space, so it does not need to go through address conversion to access the Internet. It can shorten the data transmission time between the online device and the server, shorten the time delay, and make the game more enjoyable.
