C21D-20

Description

C21D-20 is a broadband access and data transmission product that supports star or MESH networks. It supports multiple bandwidth allocations and adopts a flat system architecture design, effectively reducing system latency and improving system transmission capabilities. It features long transmission distance, large data throughput, and strong anti-interference capabilities.

Supports 800M, 1.4G, 1.5G, and 2.4G frequency bands, automatic power control, and a maximum transmission power of 30dBm. The device provides PH2.0 user interfaces.
