4. Definitions
The following terms are used in this document:
Active antenna system (AAS)
An antenna system where the amplitude and/or phase between antenna elements is dynamically adjusted, resulting in an antenna pattern that varies in response to short-term changes in the radio environment. Antenna systems used for long-term beam shaping such as fixed electrical down tilt are not considered an AAS. An AAS may be integrated in a point-to-multipoint (P-MP) hub station, base station and subscriber equipment.
AAS base station equipment
A base station equipment with an AAS.
Antenna
A radiating unit/component which contains all radiating elements forming a pattern.
Base station equipment
An equipment that provides network connectivity to, as well as management and control of, the subscriber equipment.
Channel bandwidth
The equipment’s operating bandwidth specified by the manufacturer that contains the information transmitted.
Channel frequency
The frequency at the center of the channel bandwidth.
Fixed subscriber equipment
A fixed equipment that provides connectivity between the user and the base station equipment. Fixed subscriber equipment is used at a fixed location. Fixed point-to-point, fixed point-to-multipoint, portable, mobile, and nomadic equipment are not considered fixed subscriber equipment.
Frequency block
Portions of spectrum covered by this RSS, in the band 3450-3900 MHz (see section 5.2).
Frequency block group
A continuous frequency range of one or multiple contiguous frequency blocks that contains the equipment’s channel bandwidth, as specified by the manufacturer.
Indoor base station equipment
A base station, by the nature of its design, which operates in locations completely enclosed by walls and a ceiling (e.g. a transmitter that must be connected to the alternate current (AC) power lines, an enclosure that is not waterproof, etc.)
Maximum effective isotropic radiated power (e.i.r.pmax)
The maximum average channel power in dBm measured as e.i.r.p. across all antenna elements per channel.
Maximum total radiated power (TRPmax)
The maximum average channel power in dBm measured as TRP across all antenna elements per channel
Non-active antenna system (non-AAS)
An antenna system that does not meet the definition of AAS.
Non-AAS base station equipment
A base station equipment with a non-AAS.
Point-to-point (P-P) equipment
A fixed equipment with directional antenna and is used between two fixed locations installed to provide service such as backhaul.
Point-to-multipoint (P-MP) hub equipment
A fixed equipment to provide communication with multiple user equipment installed at fixed locations.
Subscriber equipment
An equipment that provides connectivity between the user and the base station equipment. It includes but not limited to mobile, portable, nomadic, and fixed subscriber equipment.
Total radiated power (TRP)
The integral of the power transmitted by an antenna (all radiating elements), in different directions over the entire radiation sphere.
5. Transmitter standard specifications
This section sets out the requirements applicable to radio transmitters subject to this standard.
5.1 Measurement method
Unless otherwise specified, all measurements shall be performed in accordance with the requirements of RSS-Gen.
However, the alternate measurement procedure proposed in the Notice 2020-DRS0014 or alternate standards listed on ISED’s Normative Test Standards and Acceptable Alternate Procedures web page can be used to demonstrate compliance with TRP limits.
The equipment shall comply with the specified requirements while performing measurements for all operating channel bandwidths specified by the manufacturer.
AAS equipment with eight antenna elements or less can demonstrate compliance with the e.i.r.p. limits specified for non-AAS equipment in Table 1, using the standardized measurements procedures specified in RSS-Gen instead of the TRP limits.
All equipment with more than eight antenna connectors/elements shall demonstrate compliance with the TRP limits for unwanted emissions.
5.2 Band plan
The band 3450-3900 MHz is divided into 10 MHz blocks as per Standard Radio System Plan SRSP-520, Technical Requirements for Fixed and/or Mobile Systems, Including Flexible Use Broadband Systems, in the Band 3450-3900 MHz. Blocks can be aggregated to form a frequency block group larger than 10 MHz. For equipment with channel bandwidths smaller than 10 MHz, the frequency block group is 10 MHz.
5.3 Type of modulation
The modulation used shall be digital.
5.4 Frequency stability
The frequency stability shall be sufficient to ensure that the occupied bandwidth stays within the operating frequency block or frequency block group when tested at the temperature and supply voltage variations specified in RSS-Gen.
5.5 Transmitter output power
The maximum output power of the equipment measured in terms of average values shall comply with the limits specified in table 1.

Equipment shall meet the unwanted emission limits, specified below, outside each frequency block group. For each channel bandwidth supported by the equipment under test, the unwanted emissions shall be measured and reported for two channel frequencies: one located as close as possible to the low end and one located as close as possible to the high end of the equipment’s operating frequency range.
If the transmitter is designed for multi-carrier operation, the tests shall be carried out using both the maximum and minimum number of carriers intended for the equipment.
