  • Femtocell configuration using spectrum sensing
    Patent number: 8301139
    Abstract: An embodiment of the present invention provides for the ad-hoc configuration of femtocells using spectrum sensing for the selection of spectrum channels. One or more embodiments of the invention determine frequency bands that are not reserved by macrocells in a location, and perform spectrum sensing to determine communication channels in unreserved frequency bands that are being used by other femtocells in range. In this manner, femtocells can be deployed and configured in an ad-hoc manner without external coordination or control between deployed femtocells.
