Base and Repeater Stations
First Claim
1. A base station—
- repeater station pair, comprising;
a base station having an input for a broadcast signal and being arranged to transmit, in use, a transfer signal over a link using electromagnetic (EM) radiation; and
a repeater station arranged to receive, in use and through EM radiation, the transfer signal from the base station and from the transfer signal broadcast the broadcast signal using EM radiation,in which the link between the base station and the repeater station over which the transfer signal is passed in use comprises a dual polarised link, whereby the base station is arranged to transmit the transfer signal over the link with two different polarisations, and the repeater station is arranged to receive the transfer signal from the link as two differently polarised versions.

- repeater station pair, comprising;
- 21. A repeater station having two transfer antennas on which the repeater station is arranged to receive a transfer signal comprising electromagnetic (EM) radiation, two broadcast antennas on which the repeater station is arranged to transmit a broadcast signal comprising EM radiation dependent upon the transfer signal, in which the two transfer antennas are differently polarised.
- 35. A base station comprising an input for a broadcast signal, an antenna arranged to broadcast using electromagnetic (EM) radiation the broadcast signal in use and two differently polarised transfer antennas for transmitting using EM radiation a transfer signal to a repeater station such that the repeater station can rebroadcast the broadcast signal.

40. A method of operating a base station—
- repeater station pair, the pair comprising a base station arranged and a repeater station, the method comprising;
receiving at the base station a broadcast signal; transmitting a transfer signal from the base station to the repeater station over a dual polarised electromagnetic (EM) radiation link; broadcasting the broadcast signal from the repeater station using EM radiation. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
- repeater station pair, the pair comprising a base station arranged and a repeater station, the method comprising;
