NetAir 900

Digital Radio that features high performance in Ethernet networks through point to multipoint long range wireless connections at 900 MHz with throughput of up to 25 Mbps.

It is best suited for providing high performance connectivity either through bridging or routing, working at the 5 and 10MHz channels.

QoS (Quality of Service) support for the air interface and VLAN tagging for the management interface.
