![]() Single-band requirements are tested separately at the antenna connector configured for single-band operation, with all other antenna connectors terminated. At higher frequency attenuation is more hence more power will be required for signal transmission to ensure that it reaches the destination with the required minimum power.Uplink frequency is kept higher than Downlink frequency for the following reasons: So, Uplink frequency is different from downlink frequency. ![]() If the repeater is configured for single-band operation, single-band requirements shall apply to this antenna connector configured for single-band operation and no exclusions or provisions for multi-band capable repeater are applicable. Single-band transmitter spurious emissions, operating band unwanted emissions, ACLR, output intermodulation and input spurious emissions requirements apply to this connector that is mapped to single-band. For single-band connector(s), the following applies: The TDD-LTE Repeaters for mobile network are to relay RF signals for both uplink and downlink, they are effective tools to enhance mobile network coverage. For multi-band connector(s) the exclusions or provisions for multi-band apply. A downlink is a connection made in the opposite direction of an uplink, either from a satellite to the ground or from an outside network into a local network. For repeater capable of multi-band operation, various structures in terms of combinations of different downlink and uplink implementations (multi-band or single band) with mapping to one or more antenna connectors for repeater type 1-C in different ways are possible. ![]() For some requirements, it is explicitly stated that specific additions or exclusions to the requirement apply at multi-band connector(s), and multi-band RIB(s) as detailed in the requirement clause. For multi-band connector or multi-band RIB, the RF requirements in clause 6 and 7 apply separately to each supported operating band unless otherwise stated. ![]()
