Abstract: A satellite radiotelephone frequency (fU,fD) can be reused terrestrially by an ancillary terrestrial network (Fig.1) even within the same satellite cell, using interference cancellation techniques. Moreover, the ancillary network can use a modified range of satellite band forward link frequencies (f'D) for transmission, to reduce interference with out-of-band receivers. A modified range of satellite band forward link frequencies that is used by the ancillary terrestrial network can include only a subset of the standard satellite band forward link frequencies to provide a guard band, can include power levels that monotonically decrease as a function of increasing frequency and/or can include two or more contiguous slots per frame that are left unoccupied and/or are transmitted at reduced maximum power. Time division duplex operation of the ancillary terrestrial network may also be provided over at least a portion of satellite band return frequencies.

Abstract: Space-based wireless radiotelephone communications (100) are provided in a satellite footprint over a satellite radiotelephone frequency band (fD, fU). The satellite footprint is divided into satellite cells in which satellite radiotelephone frequencies of the satellite radiotelephone frequency band are spatially reused. At least one of the satellite radiotelephone frequencies (f'D, f'U) that is assigned to a given satellite cell in the satellite footprint is terrestrially reused outside the given satellite cell. A radiation pattern of at least the given satellite cell is modified to reduce interference with the at least one of the satellite radiotelephone frequencies that is terrestrially reused outside the given satellite cell.

Abstract: A radioterminal may include a transceiver, a hand-held interface coupled to the transceiver, and an interlock coupled to the transceiver. The transceiver may be configured to transmit and receive wireless communications, and the transceiver may be further configured to transmit high power communications at a high maximum power and/or EIRP and to transmit low power communications at a low maximum power and/or EIRP. The interlock may be configured to prevent the transceiver from transmitting high power communications at a power and/or EIRP that exceeds a threshold when the hand-held interface is activated. Related methods are also discussed.

Abstract: A satellite radiotelephone frequency band can be reused terrestrially by an ancillary terrestrial network even within the same satellite cell, using interference reduction/cancellation techniques. An interference reducer is responsive to a space-based component and to an ancillary terrestrial network. The interference reducer is configured to reduce interference in wireless communications that are received by the space-based component from first radiotelephones in the satellite footprint over a satellite radiotelephone frequency band using wireless communications that are received by the ancillary terrestrial network from selected ones of second radiotelephones in the satellite footprint over the satellite radiotelephone frequency band and/or wireless communications that are transmitted by the ancillary terrestrial network to the second radiotelephones in the satellite footprint over the satellite radiotelephone frequency band. The interference reducer may include a prefilter that is configured to determine the selected ones of the second radiotelephones.
