Large-Scale Peer-to-Peer Discovery Mechanism and Architecture for Frequency Allocation

Free registration required

Executive Summary

Scarcity of frequencies combined with the demand for more bandwidth is likely to increase the need for devices that provide high wireless bandwidth in limited areas while using a wired network to carry data over longer distances. Examples of such devices are Wi-Fi routers and femtocells and future devices that use TV whitespace. To utilize the available frequencies more efficiently radios must be able to find other users of the frequency bands and adapt so that they are not interfered. As transmitters hundreds of kilometers away may cause as much interference as a transmitter located next door, this mechanism can not be based on location alone.
