Client communication is compatible with all standard 802.11 ax / ac / b / g / n. This technology is improved and implemented in WIFI 5 and WIFI 6 two basic protocols. The measured 1KM transmission environment 802.11ac, MU mimo2X2 has a maximum communication rate of 540Mbps, and 802.11aX, MUmimo 4X4 has a maximum communication rate of 2.3Gbps, which fully realizes the lossless transmission and IP distribution connection with mobile 5G wireless networks. Under the condition that the input bandwidth can be expanded, 802.11ac can support 1,000 people online at the same time, 802.11ax can support 5000 people online and dozens of high-definition cameras simultaneously wireless transmission.

The device manages operations through 16 independent APs. It consists of 32 802.11ac x2, axX4 MU MIMO, adaptive beamforming and space division multiple access + smart antenna technology. Each ASIC hardware channel detection antenna cooperates with software to complete FH. -SS adaptive frequency hopping cellular network.

After many years of research on the FH-SS frequency-hopping spread spectrum and interference avoidance research, the CTUNITE team has solved the "external interference" and "multipath fading" to achieve frequency-hopping communication. When the detection environment has the same frequency interference, it automatically detects The frequency of communication change is not affected by the interference environment, and the communication is continued to avoid the interference channel.

In a complex wireless network environment, the device first performs spectrum widening on the transmitted signal before transmitting information in order to use the wide spectrum to obtain stronger anti-interference ability and higher transmission rate. At the same time, the use of different code patterns on the same frequency band can carry information of different users, which improves the frequency reuse rate of the frequency band, thereby increasing the video data interaction experience of users accessing the Internet, increasing the number of user access IPs and high-speed transmission.

With the mature commercial use of this technology, it can reduce the cost of 40% of network traffic for urban business operators, achieve a 2.5Gbps ~ 10Gbps optical fiber, and cover an outdoor network of 1 square kilometer, which will play an important key role in building a 5G network in the future. Role, non-destructive conversion of 5G network to WIFI network, low-loss transmission to customer terminals, to achieve full coverage of low-cost wireless networks in the city without dead ends, to provide smart cities with sensor networks and various types of edge intelligent computing terminals, IoT devices Data access.

This not only involves traditional commercial areas, transportation hubs, public entertainment venues, airports and other indoor areas, but also needs to focus on the effective coverage of wireless networks in a large number of outdoor areas such as industrial parks, commercial or residential neighborhoods, and surrounding scenic spots, reducing the use of Multiple optical fiber access costs have realized the high traffic cost of 5G network + the low-cost complementation of WIFI6 FH-SS adaptive frequency hopping networking, which will help accelerate the commercialization of China's 5G network construction.
