PART 2Mobile repeater devices for indoor use
Additional terms, provisions and limitations for provider-specific mobile repeater devices
Frequencies to be amplified9.
Where the mobile repeater device amplifies signals carried by a mobile network operator over an LTE system or a WiMAX system, it must also amplify signals carried by that mobile network operator over a GSM system or a UMTS system.
Automatic standby requirement10.
(1)
Where the mobile repeater device does not serve an active connection between a mobile device operating on the network of a particular mobile network operator and that particular mobile network for five minutes or more, it must ensure that any transmissions it makes on the uplink frequencies licensed to that mobile network operator 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.
Power limits11.
The mobile repeater device may only emit transmissions on frequencies licensed to a mobile network operator which—
(a)
in the frequency band 703-733 MHz or 832-862 MHz, when measured in any direction and in respect of the frequencies licensed to that mobile network operator only, have an e.i.r.p. no greater than 23 dBm;
(b)
in the frequency band 880-915 MHz, when measured in any direction and in respect of the frequencies licensed to that mobile network operator only, have—
(i)
an e.i.r.p. where those transmissions are carried over a GSM system no greater than 33 dBm;
(ii)
an e.i.r.p. where those transmissions are carried over a UMTS system no greater than 24 dBm; and
(iii)
an e.i.r.p, where those transmissions are carried over a terrestrial electronic communications network that is not a GSM system or UMTS system, no greater than 23 dBm;
(c)
in the frequency band 1710-1785 MHz, when measured in any direction and in respect of the frequencies licensed to that mobile network operator only, have—
(i)
an e.i.r.p. where those transmissions are carried over a GSM system no greater than 30 dBm;
(ii)
an e.i.r.p. where those transmissions are carried over a UMTS system no greater than 24 dBm; and
(iii)
an e.i.r.p. where those transmissions are carried over a terrestrial electronic communications network that is not a GSM system or UMTS system, no greater than 23 dBm;
(d)
in the frequency band 1920-1980 MHz, when measured in any direction and in respect of the frequencies licensed to that mobile network operator only, have an e.i.r.p. no greater than 24 dBm;
(e)
in the frequency band 758-788 MHz or 791-821 MHz, when measured in any direction and in respect of the frequencies licensed to that mobile network operator only, have—
(i)
an e.i.r.p. no greater than 17 dBm; and
(ii)
a power spectral density no greater than 10 dBm/5 MHz;
(f)
in the frequency band 925-960 MHz, when measured in any direction and in respect of the frequencies licensed to that mobile network operator only, have—
(i)
an e.i.r.p. where those transmissions are carried over a GSM system no greater than 10 dBm;
(ii)
an e.i.r.p. where those transmissions are carried over a terrestrial electronic communications network that is not a GSM system, no greater than 17 dBm; and
(iii)
a power spectral density, where those transmissions are carried over a terrestrial electronic communications network that is not a GSM system, no greater than 10 dBm/5 MHz;
(g)
in the frequency band 1805-1880 MHz, when measured in any direction and in respect of the frequencies licensed to that mobile network operator only, have—
(i)
an e.i.r.p. where those transmissions are carried over a GSM system no greater than 10 dBm;
(ii)
an e.i.r.p. where those transmissions are carried over a terrestrial electronic communications network that is not a GSM system, no greater than 17 dBm; and
(iii)
a power spectral density, where those transmissions are carried over a terrestrial electronic communications network that is not a GSM system, no greater than 10 dBm/5 MHz; and
(h)
in the frequency band 2110-2170 MHz, when measured in any direction and in respect of the frequencies licensed to that mobile network operator only, have—
(i)
an e.i.r.p. no greater than 17 dBm; and
(ii)
a power spectral density no greater than 10 dBm/5 MHz.
System gain limits12.
(1)
Where the mobile repeater device emits transmissions on frequencies licensed to one mobile network operator only, the uplink and downlink system gain must not exceed the limit in paragraph (3) where the uplink and downlink system gain is measured for each of the frequency bands being transmitted.
(2)
Where the mobile repeater device emits transmissions on frequencies licensed to more than one mobile network operator within a particular frequency band, the uplink and downlink system gain must not exceed the limit in paragraph (3) where the uplink and downlink system gain is measured separately for the frequencies licensed to each mobile network operator within that band that are being transmitted.
(3)
The uplink and downlink system gain must not exceed whichever is the smaller of—
- a)
100 dB; and
- b)
BSCL – 30 dB.
(4)
Where the mobile repeater device cannot determine the BSCL for a particular frequency band or for the frequencies licensed to a particular mobile network operator, it shall not make any transmissions on that frequency band or those frequencies (as applicable).
(5)
In this regulation, “BSCL” means base station coupling loss, which is the difference between (i) the power transmitted by the base station (which may be determined from the system information messages sent by that base station on its control channels) and (ii) the power received by the mobile repeater device from the base station (which difference shall be measured in dB).
