Abstract: A method selects a communication status for a first mobile terminal. The first mobile terminal assumes a “slave” status during a first time period and waits to see whether, by a communication request from another mobile terminal to the first mobile terminal, a connection is set up to the other mobile terminal.

Abstract: A wireless relay mitigates Radio Frequency (RF) interference. A receive antenna receives RF signals over a receive frequency band. An RF receiver processes the received signals to detect and transfer RF interference levels. The processing circuitry transfers control data to a tunable RF isolator that indicates the size of a guard band between the receive frequency band and a transmit frequency band. The guard band size is selected based on the RF interference levels for the receive frequency band at the receive antenna. The tunable RF isolator attenuates RF frequencies in the tunable guard band from corresponding RF transmit signals. A transmit antenna transfers the RF transmit signals over the transmit frequency band.
