Summary of 90 MHz Narrowband Personal Communication Testing

RSS-134 carries out standards for transmitters and receivers for narrowband personal communication services (PCS). The bands being tested are specifically within the ranges of 901 – 902, 930 – 931, and 940 – 941 MHz.

Equipment certified under this standard is classified as Category I equipment. The equipment also requires a technical acceptance certification issued by a certification bureau or body. RSS-134 is used in conjunction with RSS-Gen for general specifications and information relevant to the standard.

Scope of RSS Wireless Canadian Narrowband PCS Testing

The maximum output power, averaged over any 100 ms interval, is measured with a spectrum analyzer of resolution bandwidth wider than the occupied bandwidth of the transmitter. The video bandwidth is greater than or equal to three times the resolution bandwidth. Alternatively, the spectrum analyzer is set to the peak hold mode.

Unwanted emissions are measured when the transmitter is operating at the manufacturer’s rated power. It is also measured with signals representative of those encountered in a real system operation.

RSS-134 Testing of Wireless Narrowband Personal Communication Systems

The wireless test standard describes standard channel spacings at 12.5 and 50 kHz. The authorized bandwidth is 10 and 45 kHz bandwidth for the respective channel spacings. Channel aggregation using adjacent channels is also permitted if it is shown in the equipment certification application.

The devices can employ any type of modulation technique. However, the type used must be reported.

Stations transmitting in specified ranges within the standard wireless test method are limited to 7 watts of effective radiated power. Base stations transmitting in the 930 – 931 and 940 – 941 MHz can be certified to any manufacturer’s rated power. Lastly, for an aggregated channel, the permissible power of a single transmitter does not vary with its bandwidth.
