RSS-131, Zone Enhancers for the Land Mobile Service, dated July 2003.
This document will be in force as of its publication on Innovation, Science and Economic
Development Canada’s (ISED’s) website. However, a transition period of six (6) months
following its publication will be provided, within which compliance with RSS-131 issue 2,
or issue 3, will be accepted. After January 1, 2018, all zone enhancers sold, offered for
sale, manufactured, imported, distributed or leased on the Canadian market must comply
with RSS-131 issue 3. Equipment certified under a previous issue must be evaluated to
ensure it is compliant to issue 3. If compliant to issue 3, equipment will not require a
permissive change filing.

1. Scope
This document sets out certification requirements for zone enhancers, including Distributed Antenna
Systems (DASs) and External Radio Frequency Power Amplifiers (ERFPAs) used in conjunction with
licensed radio equipment in certain radio services.
Only zone enhancers used to increase the signal strength of radio equipment where this equipment is
certified under the following radio standard specifications (RSS) are permitted to be certified under this
RSS.
• RSS-119, Land Mobile and Fixed Equipment Operating in the Frequency Range 27.41-960 MHz
• RSS-130, Mobile Broadband Services (MBS) Equipment Operating in the Frequency Bands 698-
756 MHz and 777-787 MHz
• RSS-132, Cellular Telephone Systems Operating in the Bands 824-849 MHz and 869-894 MHz
• RSS-133, 2 GHz Personal Communications Services
• RSS-139, Advanced Wireless Services (AWS) Equipment Operating in the Bands
1710-1780 MHz and 2110-2180 MHz
• RSS-195, Wireless Communication Service (WCS) Equipment Operating in the Bands 2305-

comply with requirements specified in section 6 of this RSS.
1.1 Exclusion

radio equipment is considered to be an internal amplifier. This type of internal amplifier is a component
of that model of radio equipment which shall be certified under the applicable Innovation, Science and
Economic Development Canada (ISED) standard for that type of radio equipment. Therefore, such
internal amplifiers cannot be certified under RSS-131 and are not listed in the Radio equipment list.

2.3 Definitions
For the purpose of this standard, the following definitions apply:
Band of Operation: a frequency band that is covered under a specific RSS for specific service (e.g. the
MBS band is covered under RSS-130).
Base Station Coupling Loss (BSCL): the minimum coupling loss (in dB) between the zone enhancer’s
donor port (input port of the zone enhancer, which receives signals from the base station) and the base
station.
Block Edges: the edges at the end of the licensee’s allocated spectrum.
Consumer Zone Enhancer: a bidirectional zone enhancer, which is used by individuals to improve
wireless coverage within a limited area. Consumer Zone Enhancers are designed to be installed without
third party professional assistance and to be used “out-of-the-box” without fine tuning or other technical
adjustments.
Consumer Zone Enhancers can be operated only with approved antennas, cables and/or coupling devices
as specified by the manufacturer of the Consumer Zone Enhancer.
Distributed Antenna System (DAS): a network of spatially separated antenna nodes connected to a
common source via a transport medium that provides wireless service within a geographic area or
structure. A DAS is considered to be a zone enhancer when the network of internal antennas
communicates through the use of an amplifier that is connected to an external antenna that
communicates with a base station wirelessly.
Downlink Frequency Band: the transmitted frequency band from the base station to the subscriber.
External Radio Frequency Power Amplifier (ERFPA): a device which, inserted between a radio
transmitter (as a signal source) and an antenna, is capable of amplification of that signal and is not an
integral part of a radio transmitter. ERFPAs shall have only one transmit antenna port.
Fixed Consumer Zone Enhancer: a Consumer Zone Enhancer designed to be operated in a fixed
location in a building.
Industrial Zone Enhancer: all zone enhancers other than Consumer Zone Enhancers. The Industrial
Zone Enhancer category includes a wide variety of devices that are designed for installation by licensees
3
Zone Enhancers RSS-131
or installers approved by licensees. These devices are typically designed to serve multiple users
simultaneously and to cover larger areas, such as stadiums, airports, office buildings, tunnels and
educational campuses. Industrial Zone Enhancers include ERFPAs, repeaters, fibre optic zone enhancers
and other similar internal RF distribution methods, such as a single RF internal antenna or a DAS (an
array of internal antennas).
Mobile Consumer Zone Enhancer: a Consumer Zone Enhancer designed to be operated in a vehicle
where both uplink and downlink transmitting antenna are at least 20 cm from the user or any other
person.
Mobile Station Coupling Loss (MSCL): the minimum coupling loss (in dB) between the wireless device
which uses the Consumer Zone Enhancer and the server port (input port of the zone enhancer which
receives the signal from the wireless device) of the Consumer Zone Enhancer.
Provider-Specific Consumer Zone Enhancer: a Consumer Zone Enhancer, which can be operated only
on specific frequency ranges.
Received Signal Strength Indication (RSSI): the downlink composite received signal power (in dBm)
at the enhancer donor port in the band of operation. RSSI is expressed in negative dBm.
Uplink Frequency Band: the transmitted frequency band from the subscriber to the base station.
Zone Enhancer: a device or system that automatically receives, amplifies and retransmits the signals
received from base, fixed, mobile or portable stationswith no change in operating frequency or channel
bandwidth.
Wideband Consumer Zone Enhancer: a Consumer Zone Enhancer, which can operate on the entire
band of one or more of the service bands.

mean-square (RMS) average value.
4.2 Base Station Coupling Loss (BSCL) for Provider-Specific Consumer Zone Enhancers
In order of preference, the base station coupling loss (BSCL) is determined using one of the following
methods:

Enhancer by measuring the received forward pilot/control channel power at the zone
enhancer and reading the pilot/control transmit power from the base station as defined in the
system information messages sent by the base station
6
Zone Enhancers RSS-131
(2) estimate the BSCL by assuming that the base station is transmitting at a level of 25 dBm per
channel and by measuring the total received signal power in the channel (RPCH), received at
the zone enhancer input port (in dBm). BSCL is then calculated as BSCL = 25 − RPCH
(3) assume that the BSCL is 70 dB without performing any measurement
