Abstract
Certain antenna arrangements are provided, and active radiator units are presented which may form those antenna arrangements. Various subcomponents of such antenna arrangements and active radiator units are provided. Systems and methods, and portions thereof, facilitate the assembling and arranging of antenna elements, active radiator units, and subcomponents of such antenna arrangements and active radiator units. They also facilitate the controlling of the operation of one or more aspects of a communication site, particularly an active radiator unit within a given antenna arrangement.
Claims16
A subsystem for a cellular base station comprising:
- plural active radiator units intended to be installed at the top of a base station tower, each active radiator unit comprising:
- a radiator sub unit housed in a modular housing, said radiator subunit comprising:
- a transmit path portion;
- and/or
- a receive path portion;
- and
- an antenna arrangement coupled to said radiator sub unit, said antenna arrangement including separate transmit and receive antenna elements;
- an arrangement for conducting electrical power to said RF signal amplifiers of said radiator sub units;
- an arrangement for coupling signals to be transmitted to said radiator sub unit for transmission via said transmit antenna element;
- and
- an arrangement for coupling signals received by said receive antenna element and processed by said radiator sub unit to a receiver.
A communication site for a cellular communication system, comprising:
- a base transceiver system;
- an indoor control unit coupled to the base transceiver system;
- a radiator subunit coupled to the indoor control unit, the radiator subunit including a transmit path portion and a receive path portion;
- and
- an antenna arrangement coupled to the radiator subunit, the antenna arrangement having separate transmit and receive antenna elements, the transmit antenna element being coupled to the transmit path portion of the radiator subunit and the receive antenna element being coupled to the receive path portion of the radiator subunit,
- wherein the indoor control unit is constructed and arranged to interface the radiator subunit with the base transceiver system and to control and monitor the radiator subunit including providing an RF interface between each radiator subunit and the base transceiver system.
