GWS 5500 Series TV White Space Solution

The GWS-5500 is a significant upgrade to the fifth generation of UHF Broadband Wireless radio developed by 6Harmonics for the TVWS spectrum. Numerous enhancements to the Networking, Mechanical and RF sections greatly improve performance and usability, while remaining backward compatible with the GWS-5000. The GWS-5500 series is the most advanced, highest power 2x2 MIMO UHF Broadband solution currently available in the market. Ideal for challenging links such as those facing in-band noise & interference or even Non-Line-of-Sight conditions, the GWS-5500 has the power and features to ensure a rock-solid, high- capacity PTP & PMP connection.
