RSS-140 — Equipment Operating in the Public Safety Broadband Frequency Bands 758‑768 MHz and 788‑798 MHz

1. Scope

This Radio Standards Specification (RSS) sets out certificationrequirements for equipment operating in the public safety broadband frequency bands758-768 MHz and 788-798 MHz.

1.1 Enforcement date

This document will be in force as of its publication onInnovation, Science and Economic Development Canada’s (ISED) website.

2. General requirements and information

2.1 Certification

Equipment covered by this standard is classified as CategoryI equipment. Either a technical acceptancecertificate (TAC) issued by ISED’s Certification and Engineering Bureau or acertificate issued by a certification body (CB) is required.

2.2 Licensing

The equipment covered by this standard is subjectto licensing, pursuant to subsection 4(1) of the RadiocommunicationAct.

2.3 RSS-Gen compliance

RSS-140 shall be used inconjunction with RSS-Gen, GeneralRequirements for Compliance of Radio Apparatus, for generalspecifications and information relevant to the equipment covered by thisstandard.

SRSP – Standard Radio System Plan

2.5 Definitions

Mobile equipment is equipment that is designedfor use while in motion as well as during halts at unspecified points in whichthe radiating antenna is at least 20 cm away from the human body.

Portable equipment is equipment with anembedded radiating antenna having contact directly with or within 20 cm of thehuman body.

3. Measurement methods

3.1 Transmitter output power

The transmitter output powershall be measured in terms of average power.

3.2 Transmitter unwanted emissions

The equipment’s emissions shall be measured with the carrierfrequency set at the highest settable frequency and at the lowest settablefrequency permitted by the design of the equipment.

4. Transmitter specifications

4.1 Types of modulation

Equipment shall employ digital modulation techniques.

4.2 Transmitter frequency stability

The frequency stability shall be sufficient to ensure thatthe occupied bandwidth stays within the operating frequency block when tested atthe temperature and supply voltage variations specified in RSS-Gen.

4.3 Transmitter output power

The equivalent radiated power (e.r.p.) for control andmobile equipment shall not exceed 30 W. The e.r.p. for portable equipmentincluding handheld devices shall not exceed 3 W.

Fixed and base station equipment shall comply with the e.r.p.limits in SRSP-540.

In addition, the peak to average power ratio (PAPR) of theequipment shall not exceed 13 dB for more than 0.1% of the time, using asignal that corresponds to the highest PAPR during periods of continuoustransmission.

4.4 Transmitter unwanted emission limits

The power of any unwanted emission outsidethe bands 758-768 MHz and 788-798 MHz shall be attenuated below the transmitteroutput power P in dBW as follows, where p is the transmitter output power in watts:

1. For any frequency between 769-775 MHz and 799-806 MHz:
   1. 76 + 10 log (p), dB in a 6.25 kHz band for fixed and base station equipment
   2. 65 + 10 log (p), dB in a 6.25 kHz band for mobile and portable/hand-held equipment
2. For any frequency between 775-788 MHz, above 806 MHz, and below 758 MHz: 43 + 10 log (p), dB in a bandwidth of 100 kHz or greater. However, in the 100 kHz bands immediately outside and adjacent to the frequency bands 758-768 MHz and 788-798 MHz, a resolution bandwidth of 30 kHz may be employed.

In addition, the equivalent isotropically radiated power (e.i.r.p.) of all emissions, including harmonics in the band 1559-1610 MHz, shall not exceed −70 dBW/MHz for wideband emissions, and −80 dBW/kHz for discrete emissions ofless than 700 Hz bandwidth.
