Withdrawal of RSS-139

Notice is hereby given that Industry Canada is withdrawing from publication Radio Standards Specification 139 (RSS-139), Licensed Radiocommunication Devices in the Band 2400-2483.5MHz.

The purpose of RSS-139 was to permit certification of field disturbance sensors and spread spectrum devices in the 2400-2483.5 MHz band that could not meet conditions allowing them to operate license-exempt under RSS-210. Equipment certified under RSS-139 was subject to licensing in order to provide protection to licensed radio relay fixed service systems and licensed TV pick-up links also operating in the 2400 MHz band.

As a result of an Industry Canada policy directive (Spectrum Utilization Policy SP-2285 MHz, June, 2001) that went into effect July  1, 2002, radio relay fixed service systems and TV pick-up radio links operating in the 2400-2483.5 MHz band have not been protected since that date. As RSS-210 already contains the technical requirements necessary under the new rules, RSS-139 is no longer needed and is therefore withdrawn from publication as of the date of this Notice.

All equipment certifications that were granted under RSS-139 are grandfathered and thus remain valid.

Amendments to RSS-210

Notice is also given that Industry Canada is releasing the following document: RSS-210, Issue 5: Amendment. This document sets out changes to RSS-210, Issue 5, which are described below.

The first change concerns special conditions that had to be satisfied by spread spectrum devices and field disturbance sensors operating in the 2400-2483.5 MHz band for license-exempt operation. As a result of SP-2285 MHz (referenced above), these special conditions are no longer applicable and are therefore eliminated, permitting all devices and field disturbance sensors compliant with RSS-210 to operate license-exempt.

The second change is to requirements for spread spectrum devices operating in the
902-928 MHz, 2400-2483.5 MHz and 5725-5850 MHz bands. For all three bands, the requirements have been amended so as to now permit the certification of any device employing digital modulation techniques using a 6 dB bandwidth of at least 500 kHz . Also, the processing gain requirement for spread spectrum devices has been eliminated and the requirements governing frequency-hoping devices has been modified.

RSS-210, Issue 5: Amendment will go into effect on the date of publication of this Notice.

Where there is discrepancy between the existing text of RSS-210, Issue 5 and the Amendment, the Amendment shall take precedence.
