Abstract

A wireless device, comprising a plurality of radios wherein at least two of the plurality of radios are capable of operating within predetermined parameters. The wireless device may further include modules capable of dynamically selecting the most appropriate radio based on the predetermined parameters. The predetermined parameters may be predetermined power levels and the modules may select the most appropriate radio based on power requirements determined by systems profiles. In addition to or in lieu of the predetermined power levels, the modules may select the most appropriate radio based on requirements determined by network conditions.

7. The wireless device of claim 6, wherein said radio monitoring and radio selection uses a Radio Information Model (RIM).

8. The wireless device of claim 1, wherein said plurality of radios are a hierarchy of radios, said hierarchy based upon power, range or throughput and said most appropriate radio is selected from said hierarchy of radios.

9. The wireless device of claim 6, wherein said radio selection uses a set of heuristics used to determine when to select the most appropriate radio.

10. The wireless device of claim 9, wherein said wireless device is capable of a deep packet inspection of a transmitted packet, inspection of packet size to send or inspection of periodicity of traffic in order to determine the type of packet.

11. The wireless device of claim 6, wherein said modules further comprise transport address mapping.

12. The wireless device of claim 6, wherein said modules comprise:

(a) determining if there is a current packet to send, and if not, enabling a low power radio, and if so, determining if said wireless device is currently on a high power radio, and if it is, transmitting said packet on said high power radio;

(b) incrementing a packet count if said wireless device is not currently on said high power radio and determining if said packet count is above a predetermined threshold;

(c) initiating a control protocol to switch to said high power radio for a next packet once said predetermined threshold is met;

(d) determining, if said threshold in step (c) is not met, whether or not to do a deep packet inspection and, if not, send said current packet on said low power;

(e) determining, if a deep packet inspection is to be done in step (d), if the current packet is a real time packet, and if not, sending current packet on said low power radio; and
