The ZKManet4371D is a MESH narrowband portable base station
specially designed to deal with emergencies and realize rapid
deployment. The whole device is designed with all-cast aluminum
structure according to the quality requirements of standard, which
meets the requirements of IP67 dustproof and waterproof, and can
adapt to various harsh working field environments and meet the
needs of high-strength communication. The device supports the
piggyback fast deployment method, supports the self-organized
network co-frequency relay, and adaptively adjusts the transmit
power according to different configurations.
