Abstract
A radio-frequency (RF) repeater, including a first repeating section which is adapted to receive and amplify forward-signals from a first transceiver so as to generate amplified-forward-signals and to radiate the amplified-forward-signals to a second transceiver. The first section also receives and amplifies reverse-main-signals from the second transceiver so as to generate amplified-reverse-main-signals and transmits the amplified-reverse-main-signals to the first transceiver. The repeater includes a second repeating section which is adapted to receive and amplify reverse-diversity-signals from the second transceiver so as to generate amplified-reverse-diversity-signals and transmits the amplified-reverse-diversity-signals to the first transceiver.

A radio-frequency (RE) repeater, comprising:
- a first signal path, which is adapted to receive and amplify forward-signals that are transmitted from a base station using a main repeater section so as to generate amplified-forward-signals and to radiate the amplified-forward-signals by a first auxiliary repeater section in a first geographic region and by a second auxiliary repeater section in a second geographic region, via main auxiliary antennas at each of the auxiliary repeater sections and to receive and amplify reverse-main-signals from each of the auxiliary repeater sections so as to generate amplified-reverse-main-signals and to transmit the amplified-reverse-main-signals to the base station via the main repeater section;
- and
- a second signal path, which is adapted to receive and amplify reverse-diversity-signals from diversity antennas at each of the auxiliary repeater sections that are in different geographic regions so as to generate amplified-reverse-diversity-signals and to transmit the amplified-reverse-diversity-signals via a main repeater section diversity antenna to the base station.
A method for repeating radio-frequency (RF) signals, comprising:
- receiving in a first repeating section of a main repeater forward-signals from a base station;
- amplifying the forward-signals in the first repeating section so as to generate amplified-forward-signals;
- radiating the amplified-forward-signals from the first repeating section to a first auxiliary repeater in a first geographic location and a second auxiliary repeater in a second geographic location;
- receiving in the first auxiliary repeater and the second auxiliary repeater reverse-main-signals from the first and second geographic areas and radiating the reverse-main-signals to the first repeating section;
- amplifying the reverse-main-signals in the first repeating section so as to generate amplified-reverse-main-signals;
- transmitting the amplified-reverse-main-signals from the first repeating section to the base station;
- receiving in the first auxiliary repeater and the second auxiliary repeater reverse-diversity-signals from the first and second geographic areas and radiating the reverse-diversity-signals to a second repeating section in the main repeater;
- amplifying the reverse-diversity-signals in the second repeating section so as to generate amplified-reverse-diversity-signals;
- and
- transmitting the amplified-reverse-diversity-signals from the second repeating section to the base station.
A radio-frequency (RF) repeater, comprising:
- a first repeater, which is adapted to receive and amplify forward-signals from a first transceiver so as to generate amplified-forward-signals and to receive and amplify reverse-main-signals and reverse-diversity-signals from at least second and third repeaters so as to generate amplified-reverse-main-signals and amplified-reverse-diversity-signals, and to transmit the amplified-reverse-main-signals and amplified-reverse-diversity-signals to the first transceiver;
- and
- at least second and third repeaters operably interconnected to the first repeater, which are adapted to radiate the amplified-forward-signals to a second transceiver, to receive reverse-main-signals and reverse-diversity-signals from the second transceiver, and to provide the reverse-main-signals and reverse-diversity-signals to the first repeater, the second and third repeaters transmitting and receiving signals from respective second and third geographic regions.
