A range equalization transceiver system () for increasing efficiency of a continuous duty communications link includes a first transceiver () for transmitting data traffic over a broadband traffic channel and a second transceiver () for determining routing information using a discovery channel based on link quality. A controller () is used for interpreting routing information from the second transceiver () where the controller () 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.

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.

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 () includes discovering all available delivery options (). One or more operational parameters are detected () including information based on the agent's knowledge of the user's schedule. The impact on battery consumption of the communication is also estimated () and a key metric is determined () based on the type of delivery options that are available. Finally, an optimal delivery option is determined () where it can be either automatically selected or presented to the user of the device.

Each node in a wireless communication network adds information in hello messages wherein the information comprises the number of hello messages received at the node from a plurality of nodes. Also, the nodes are configured to determine the node density based on additional information extracted from the received hello messages. For example, a first node in the wireless communication network receives a hello message from a second node, wherein the hello message comprises additional information indicating at least a number of hello messages received by the second node from a plurality of nodes in the wireless communication network. The first node extracts the additional information from the received hello message and based on the extracted additional information, the first node determines at least one channel performance metric. Based on the at least one channel performance metric the first node determines density of neighboring nodes in the wireless communication network.

A wireless communication system (100) that includes a plurality of base sites (101-103) employs a method and apparatus for determining a location of a communication unit (107) in the system. Upon transmission of an information signal (109) by the communication unit, each of the base sites receives the transmitted information signal. A serving base site (e. g. , 103) determines a stream of information symbols from the information signal, derives timing information based on the information signal and the stream of information symbols, and conveys the stream of information symbols preferably to at least two non-serving base sites (101-102). The non-serving base sites determine respective timing information based on the information signal received from the communication unit and the stream of information symbols received from the serving base site. The location of the communication unit is then determined by either a base site or a stand-alone processing device (105) based on the serving base site's and non-serving base site's timing information.
