X Band - Terrestrial Communications and Networking

Terrestrial Communications and Networking

In Ireland, Libya, Saudi Arabia and Canada, the X band 10.15 to 10.7 segment is used for terrestrial broadband. Alvarion, Cambridge, and Ogier make systems for this, though these are all incompatible. The Ogier system is a full duplex Transverter used for DOCSIS over microwave. The home / Business CPE has a single coaxial cable with a power adapter connecting to an ordinary cable modem. The local oscillator is usually 9750 MHz, the same as for K_u band satellite TV LNB. Two way applications such as broadband typically use a 350 MHz TX offset.
