BT 80G



BT 80G is a Full-Duplex microwave link operating in the 71-76 / 81-86 GHz license-free band. The BT 80G link can provide up to 2 Gbps throughput using 16 QAM modulation and 750 MHz bandwidth. The Radio also includes advanced Ethernet settings.

It is designed as a Full Outoor Unit (unit L and H) with direct mounting to a parabolic antenna. These properties give service providers great flexibility and speed in building up their networks. Top-quality components and durable cast-aluminium design allows the radio link to be used in very difficult climatic conditions.
This PtP technology has been developed and manufactured by SUMMIT DEVELOPMENT, an established Czech manufacturer of microwave links, at their own software digital radio.
