Scope
This specification applies to Mobile Repeaters (Signal Boosters).
Signal Boosters or mobile repeaters are devices used to extend the coverage of
mobile networks in areas where the surroundings are preventing a suitable
reception of radio waves like inside a car or high building.
Enforcement
This specification shall enter into force on 01/06/2021.
Any previous version of this technical specification is withdrawn.

General Requirements
All equipment must comply with the requirement of CITC specification GEN001,
be safe and must not adversely affect other electrical equipment.
All telecommunications and radio terminal equipment must comply with the
relevant technical specifications established by CITC. In addition, such equipment
may be subject to regulations for Declaration of Conformity or registration. See
www.citc.gov.sa for details.
If more than one interface type is offered by a piece of equipment, each interface
must meet the applicable technical specifications.
Further information on the characteristics and presentation of network interfaces
can be found by visiting operator's website.
It is mandatory that test reports are obtained from a laboratory that has been
accredited by a body that is a member of the ILAC Mutual Recognition
Arrangement.
Limits and conditions
Testing should be carried out to ensure compliance with the listed specifications.

Licensing Requirements
Importing mobile repeaters devices is only allowed for service providers licensed
by CITC.
Additional Requirements
In addition to meeting all the requirements detailed in the “Regulations for Selling
and Using Mobile Repeaters”, all mobile repeaters must comply with the following:
Automatic Standby/Shutoff
Signal Boosters and Repeaters must show an automatic standby/shutoff mode
which will reduce the repeater output power to no more than -70 dBm/MHz while
not in use for more than 1 minute.
Anti-Oscillation
The repeater or signal booster must deploy an anti-oscillation detection and
mitigation feature that shows its results within 0.3 seconds for the uplink and 1
second for the downlink. The device shall either power off, restart or reduce its
output power until oscillations are no longer detected.
Gain
The overall maximum system gain of the repeater or signal booster, referenced to
its input and output ports, is limited to 100 dB for indoor use and 20 dB for
vehicular use. The system gain shall be calculated as the difference between the
carrier power received at the devices input port and the carrier power submitted
at the devices output port.
7
Gain Control
The repeater or signal booster must be capable of automatic gain control to
protect against excessive input signals- The gain adjustment shall limit the uplink
noise to: -103 dBm/MHz – RSSI where RSSI is the Received Signal Strength
expressed in dBm per band of operation at the port of the device.
The device must power off completely if the restrictions can not be met.
