Abstract
A set of spread-spectrum units is capable of operating as a base station or as a remote unit. Each spread-spectrum unit includes a base subunit or a remote subunit, each subunit having a receiver for receiving spread-spectrum signals at a first frequency transmitted from the spread-spectrum units; a signal despreader for despreading the spread-spectrum; a demodulator for demodulating the despread-spread-spectrum signals; a combiner for combining the demodulated signals, and a local signal; a converter for converting the combined signal to a base-data signal; a spread-spectrum circuit for processing the base-data signal; and a transmitter for transmitting at a second frequency the processed base-data signal as a base-spread-spectrum signal.
Claims16
A mobile communication unit comprising:
- an antenna and circuitry configured in a first mode, to receive first data from a first communication unit and to output the received data to a user of the mobile communication unit;
- the antenna and circuitry configured in a second mode, to receive second data from a second communication unit and to transmit the received second data to at least one of a plurality of third mobile communication units;
- and
- the antenna and circuitry configured to switch from the first mode to the second mode in response to an input from the user of the mobile communication unit.
A method comprising:
- switching, by a mobile communication unit, between a first mode and a second mode in response to an input from a user of the mobile communication unit;
- on a condition that the mobile communication unit is in the first mode, receiving first data from a first communication unit and outputting the received data to the user of the mobile communication unit;
- and
- on a condition that the mobile communication unit is in the second mode, receiving second data from at least one second communication unit and transmitting the received second data to at least one of a plurality of third mobile communication units.
