FCC officials were on hand as witnesses.

Demonstrations are to continue through Thursday. Sirius XM said in a May letter to OET that demonstrations should be aimed at “helping the Commission to decide on key operating parameters such as maximum operating power and the out-of-band emissions ('OOBE') requirements for mobile transmitters, so that the Commission can develop specific rules to maximize WCS service potential while protecting existing service to 19 million satellite radio consumers.”
