3.1 Definitions

For the purposes of the present document, the following terms and definitions apply:

broadband repeater: repeater which is designed for operation on any combination of ARFCNs (up to a specified maximum number) within the operating band of the repeater.

channelized repeater: repeater which is designed for operation on a specified subset of ARFCNs within the operating band of the repeater. The subset of ARFCNs may be determined during the manufacture of the repeater, or may be programmable.

GSM: Unless otherwise specified, references to GSM include all radio frequency bands according to clause 4.1.

operating band: the frequency range in which GSM operates.

pass band: frequency range that the repeater operates in with operational configuration.

NOTE 1: This frequency range can correspond to one or several consecutive nominal channels. If they are not consecutive each subset of channels shall be considered as an individual pass band.

NOTE 2: A repeater can have one or several pass bands.

repeater: bi-directional Radio Frequency (RF) amplifier which can amplify and transmit a received Mobile Station (MS) signal in the GSM MS transmit band, simultaneously it can amplify and transmit a received Base Transceiver Station (BTS) RF signal in the GSM BTS transmit band.

repeater system using frequency shift: repeater system consisting of two different elements, a master unit close to the BTS and at least one remote unit close to the area to be covered.

NOTE 3: The master unit amplifies the channels from the BTS and shifts them to different GSM channels. In the remote unit the shifted channels from the master unit will be transferred back to the original channels and amplified. This is valid for the downlink signals as well as for the uplink signals.

spurious emissions: emissions at frequencies other than those of the carrier and sidebands associated with normal modulation and switching.

subchannel power imbalance ratio on downlink: as defined in 3GPP TS 45.004 [21].
