In a wireless ad hoc network () of nodes (), a method () of power management entails monitoring () a current traffic load of the network (), and in response to the current traffic load, selecting () a subset () of epochs () within cyclically repeating time windows () for network communication. A message () is communicated () between the nodes () in the network (). The message () identifies the subset () of epochs () for using in communicating network traffic (). Following receipt of the message, each of the nodes () modifies () a transmit capability mode by entering a run state () during the epochs () within the subset () to enable communication of network traffic () and by entering a low power consumption idle state () during the remaining epochs () within the time window ().

Power management in a wireless ad hoc network

A communications system () includes a resource controller () and a terminal () in communication with the resource controller (). Periodically, the resource controller () sends a service announcement () that identifies a set () of timeslots () within a communication resource () configured for random access within a future frame (). The terminal () ascertains a burst characteristic () of a message () to be sent from the terminal () and generates a random access parameter (). The terminal () selects one of the timeslots () from the set () in accordance with the random access parameter (), the timeslot exhibiting a burst type () corresponding to the burst characteristic () of the message (). The terminal () transmits the message () in the selected timeslot ().

Random access slot selection in a communications system

A base station () provides service in a satellite communications (SATCOM) system () to a terminal (). The SATCOM system () operates in accordance with a first standard (), and the terminal () is unable to communicate in accordance with the first standard (). Methodology entails receiving, at a SATCOM resource controller (), a request () for a satellite resource () from the base station (). The satellite resource () is allocated to the base station () and the controller () sends a message () with the allocated satellite resource (). The base station () applies a second standard (), defining a specific set of functional and performance characteristics, to the satellite resource (). The terminal () is enabled to perform satellite communications in accordance with the second standard () using the satellite resource ().

Providing service in a satellite communications system to disadvantaged terminals

A wireless network () includes a number of definable radio systems () in communication with one another via a wideband backbone (). Each of the systems () includes a first software programmable transceiver () for extra-network communication using a narrowband channel defined by a radio frequency capability (). Each of the radios () further includes a second transceiver for intra-network communication using wideband backbone (). Methods for operating the network () enable the radios () to engage in communication over narrowband channels to carry a signal between multiple radios () and an extra-network location, and for communicating the signal as distinct bitstreams between the radios () and another of the radios () using the wideband backbone (). In addition, methods enable the radios () to monitor multiple external networks concurrently by having each of the radios () use a different RF capability (), and to combine their independently received signals to improve performance and suppress interference.
