[1] MDS Operations, an affiliated company, participated in recent auctions in 2005 and 2006 held by the Federal Communications Commission (FCC) of the frequency band of 12.2 - 12.7 GHz, which it christened "MVDDS".

The system operates using MVDDS to cover an entire Metro area providing 50 Mbit/s of wireless Internet to the home.

In 2004, a jury in Federal Court in Ft. Pierce, Florida invalidated both asserted Northpoint patents on four separate grounds.
