3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
Donor coupling loss: is the coupling loss between the repeater and the donor base station.
Down-link: signal path where base station transmits and mobile receives
Maximum output power, Pmax: This is the mean power level per carrier measured at the antenna connector of the Repeater in specified reference condition.
Pass band: the Repeater can have one or several pass bands. The pass band is the frequency range that the Repeater operates in with operational configuration. This frequency range can correspond to one or several consecutive nominal 5 MHz channels. If they are not consecutive each subset of channels shall be considered as an individual pass band.
Repeater: a device that receives, amplifies and transmits the radiated or conducted RF carrier both in the down-link direction (from the base station to the mobile area) and in the up-link direction (from the mobile to the base station).
Up-link: signal path where mobile transmits and base station receives.
