Hikvision 20KM 5GHz 867 MBPS Wireless Bridge

Sold by HIKLINK SECURITY · Kumasi Metropolitan

Because 20 km is an extreme distance for an unlicenced 5 GHz frequency, you will need a device equipped with a high-gain, highly directional dish antenna (at least 23 dBi to 26 dBi) to keep the 867 Mbps link stable.
