ABSTRACT:
Wireless access to a network2by an isolated user1includes the isolated user1transmitting a wireless signal intended to produce interference at nodes included in a group3, 4and9of nodes, that have access to the network2. Upon the interference being detected by a member of one of the groups, and a link established between the isolated user1and the member of the group, access to the network2is arranged for the isolated user1. In one method, the isolated user is unlicensed and seeks access to the network via a licensed part of the wireless spectrum.
