On 31 January 2023, ISED published RSS-132 issue 4 on its website, replacing RSS-132 issue 3. The old standard had a six-month transition period from the date of publication.

During the transition period, certification applications under either RSS-132 issue 3 or RSS-132 issue 4 were accepted. After that period, only applications under RSS-132 issue 4 are accepted.

Updated parts:

The clause on receiver spurious emissions is deleted.

Definitions of mobile equipment and portable equipment are added:

Mobile equipment: designed for use while in motion or while stationary at unspecified points, with the radiating antenna at least 20 cm from the human body.

Portable equipment: equipment with an embedded radiating antenna that comes into direct contact with, or within 20 cm of, the human body.

The transmitter radiated power for mobile equipment is changed from effective isotropically radiated power (e.i.r.p.) to effective radiated power (e.r.p.).

The e.r.p. of mobile equipment must not exceed 7 W.

Section 4 on external controls, mobile equipment identifiers (MEID) and international mobile equipment identity (IMEI) is deleted.

The frequency stability requirement is amended.

Frequency stability shall be sufficient to ensure that the occupied bandwidth remains within each sub-band when tested under the temperature and supply voltage variations specified in RSS-Gen.

Requirements for portable equipment are added.

The e.r.p. of portable equipment must not exceed 3 W.
