Point-to-Point Broadband Wireless Access

RAD’s Airmux-400 series of point-to-point broadband wireless radios deliver native Ethernet and TDM services over a single wireless link in various sub-6 GHz frequencies. With high capacity, the Airmux-400 radio systems boast an impressive aggregated throughput of up to 2.5 Gbps (Airmux-400E) and a remarkable range of up to 120 km (75 miles). These radio systems incorporate advanced features, including MIMO and OFDM, ensuring optimal performance and unmatched robustness in diverse environments. 

Superb point-to-point wireless performance

The Airmux-400 radio systems incorporate advanced features, such as MIMO, OFDM and high modulation schemes. Furthermore, unique air interface capabilities ensure optimal performance and high spectral efficiency in dense radio environments and multipath conditions. This makes the Airmux-400 ideal for utilities AMI/DA backhaul, public safety and government backhaul, and transportation (highways and railways backhaul). Airmux-400 products comply with worldwide regulations and standards and are deployed globally by leading service providers, as well as operators of public and private networks requiring high-capacity connectivity.
