In scenarios with extremely high requirements for bandwidth and communication link integrity such as carrier-grade communication, large-scale industrial networking and emergency command, the Carrier-Grade High Bandwidth Series and Wireless Peripheral Communication System have become a "core + supporting" combination of tqwifi's wireless communication system. The former guarantees high-bandwidth and high-reliable core data transmission, and the latter improves the peripheral supporting of communication links, creating a full-link and integrated wireless communication solution.
