Technology
These two satellite services, and their older Fixed Service Satellite technology, were provided to add additional capacity that lets DISH Network satisfy the Federal Communications Commission's "must-carry" requirements for local channels, and make room for HDTV. In addition, several dozen international services have been added to DISH Network's channel line-up. The SuperDish receives standard Direct broadcast satellite (DBS) services in circular polarization at 12.7 GHz from Echostar's existing 110°W and 119°W slots. The 105°W and 121°W slots are received in linear polarization at 11.7 GHz at a much lower power. As a result, SuperDISH-compatible receivers must be able to receive circularly-polarized and linearly-polarized signals at two different frequency ranges from up to four satellites.

Famous quotes containing the word technology:
“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”
—Freeman Dyson (b. 1923)
