Abstract: A range equalization transceiver system (100) for increasing efficiency of a continuous duty communications link includes a first transceiver (105) for transmitting data traffic over a broadband traffic channel and a second transceiver (107) for determining routing information using a discovery channel based on link quality. A controller (103) is used for interpreting routing information from the second transceiver (107) where the controller (103) selects a transmitting scheme based on data traffic conditions on both the broadband traffic channel and link quality channel for sending data over a wireless network.

Abstract: A method for utilizing a personal agent in a communications device for selecting the method of delivery of at least one communication having multiple networking type modes (200) includes discovering all available delivery options (203). One or more operational parameters are detected (205) including information based on the agent's knowledge of the user's schedule. The impact on battery consumption of the communication is also estimated (209) and a key metric is determined (211) based on the type of delivery options that are available. Finally, an optimal delivery option is determined (213) where it can be either automatically selected or presented to the user of the device.

Abstract: Signal-strength measurements are periodically made for all nodes within communication range of a node. The time-varying nature of the signal-strength measurements are taken into account prior to any node being used for routing purposes. More particularly, if the time-varying nature of a node's signal strength indicates that it is traveling at a high speed, the node is not utilized for routing purposes.
