GP-AP320BK is a 2.4G band 300mbps embedded wireless AP card. It uses industrial high-performance high-throughput processing chip. It is a wireless AP product for intrinsic safety which is specially developed for coal mines. Gp-ap320 supports 12-24 V DC wide voltage power supply (peak current less than 260 MA) and Poe power supply. It adopts industrial grade high-performance high pass chip and external FRP omnidirectional antenna or plate-shaped directional antenna, so that the radiation radius of receiving and transmitting can reach more than 300 meters. This product supports relay and wireless ISP In addition, it also supports gateway and AP functions, which is suitable for wireless networking and wireless coverage.

GP-AP320BK adopts the latest high pass customized chip optimization algorithm, which has the characteristics of strong anti-interference ability, high bandwidth, high standby capacity and strong stability. At the same time, it supports the integrated mode of fat and thin, graphical fast configuration mode, typical functions: access signal threshold limit, multi virtual SSID, maximum client number limit, VLAN, QoS speed limit rules, WDS, national and regional settings, advanced RF mode, etc. A large number of imported high specification industrial chips are used in the main board chip of the equipment to ensure stable operation in the harsh high temperature, high cold and high humidity environment at - 40 ~ 80 ℃.
