Miure :: DUO 5 High Throughput 5GHz Radio Link

Duo 5 is a 5GHz wireless Ethernet bridge using the MRTP technology designed exclusively for systems with separate radios for data transmission and reception. Duo 5 is capable of transmission with much higher speeds than devices using carrier multiple access (CSMA/CA, TDMA, polling), ie. IEEE 802.11 (WiFi), especially on very long-range connections.

Duo 5 is based on two radio modules working in 5GHz band and on a dual polarized antenna. The device is enclosed in a compact, weatherproof enclosure with a simple mounting system.
