The network
A packet-based, hierarchical communication system, arranged in a spanning tree configuration, is described in which wired and wireless communication networks exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. The network accommodates real time voice transmission both through dedicated, scheduled bandwidth and through a packet-based routing within the confines and constraints of a data network. Conversion and call processing circuitry is also disclosed which enables access devices and personal computers to adapt voice information between analog voice stream and digital voice packet formats as proves necessary. Routing pathways include wireless spanning tree networks, wide area networks, telephone switching networks, internet, etc., in a manner virtually transparent to the user. A voice session and associate call setup simulates that of conventional telephone switching network, providing well-understood functionality common to any mobile, remote or stationary terminal, phone, computer, etc.

The device of claim 1 wherein the contents of each digital voice packet transmitted wirelessly by a communication device of a first party is received in a digital voice packet by a destination party. 10. The device of claim 1 wherein the communication network comprises a plurality of access devices, and wherein routing of digital voice packets between access devices is based upon a cost. 11. The device of claim 1, wherein a user is prompted to select a routing alternative using routing information received by the communication device. 12. The device of claim 1, wherein the wireless communication circuitry comprises at least one wireless receiver and at least one wireless transmitter. 13. The device of claim 12, wherein the at least one wireless receiver and the at least one wireless transmitter comprises a single transceiver. 14. The device of claim 1, wherein the wireless communication circuitry comprises at least one transceiver. 15.
