Textual Amendments

F1 Reg. 13 omitted (29.2.2024) by virtue of The Wireless Telegraphy (Mobile Repeater) (Exemption) (Amendment) Regulations 2024 (S.I. 2024/136), regs. 1, 2(4)

Automatic standby requirement U.K.

14.—(1) Where the mobile repeater device does not serve an active connection between a mobile device and a mobile network for five minutes or more, it must ensure that any transmissions it makes using the uplink frequencies comply with the limit in paragraph (2).

(2) The transmissions, when measured in any direction, must have an uplink noise power which does not exceed -70 dBm/MHz e.i.r.p.

Limits on power spectral density U.K.

15.—(1) The mobile repeater device may only emit transmissions on uplink frequencies in a particular frequency band which, when measured in any direction, have a power spectral density no greater than 17 dBm/5 MHz.

(2) The mobile repeater device may only emit transmissions on downlink frequencies in a particular frequency band which, when measured in any direction, have a power spectral density no greater than 10 dBm/5 MHz.

System gain limits U.K.

16.—(1) When measured separately for each of the frequency bands being transmitted—

(a) the uplink and downlink system gain must not exceed whichever is the smaller of—

(i) 100 dB; and

(ii) 10 dB – RSSI; and

(b) the uplink and downlink system gain must be equal.

(2) In this regulation, “RSSI” means received signal strength indicator, which is the total downlink signal power received at the donor port of the mobile repeater device, for all base stations in the frequency band being transmitted (and which shall be measured in dBm).

I3 Reg. 16 in force at 16.6.2022, see reg. 1

Limit on transmitted intermodulation products U.K.

17.—(1) For each frequency band that is being transmitted by the mobile repeater device, the power level of transmitted intermodulation products due to input signals within that frequency band shall not exceed −19dBm at the donor port and coverage port of that device.

(2) In this regulation, “transmitted intermodulation products” due to input signals within a frequency band means any signals transmitted by the mobile repeater device within that frequency band which have been created from the non-linear combination of two or more input signals within that frequency band.
