A wireless networking system uses mobile and fixed transceivers to achieve a network with changing topology. A routing process includes quality-of-service considerations in the network to allow for features such as file or other data transfer, streaming audio and video, digital telephone communications, etc. The routing process adapts to transceiver units entering, leaving, or moving within, the network. Auxiliary networks such as the Internet, campus or corporate intranets, home networks, etc., can be accessed through the wireless network. Features, designs and user interfaces for the units are described. Security and access control of media content and other data is presented.
