RSS-213 — 2 GHz Licence-Exempt Personal Communications Service Devices (PCS)

5. General Standard Specifications

If the PCS equipment is a cordless telephone, the following applies.

The base station shall be certified under both this standard (RSS-213) and the Industry Canada standard CS-03 for certification of terminal equipment.

Cordless telephones shall have circuitry which makes use of a digital code word in the dialling and ringing function to provide protection against unintentional line seizure and dialling, and unintentional ringing of the handset in the following (or equivalent) manner:

Access to the telephone network shall be preceded by the transmission of a code word from the handset. This code word shall be one of at least 256 possible combinations (i.e. 8 or more bits). Access to the telephone network is to occur only if the code word transmitted by the handset matches that used in the base station. Similarly, ringing of the handset shall be permitted to occur only if the code word transmitted by the base station matches the code word in the handset.

For a good geographical distribution of users of the possible combinations of digital security codes the manufacturer must incorporate one of the following provisions:

• Provide means for the user to readily select one of the security codes. The telephone shall be either in a non-operable mode after manufacture until the user selects a security code or the manufacturer must continuously vary the initial security code as each telephone is pro­duced; or
• Provide a fixed security code at the time of manufacture that is continuously varied either randomly or sequentially; or
• Provide a means for the telephone to automatically select a different security code each time the telephone is activated or dialled; or
• Provide a combination of the above, or any method satisfying its intent.

Details concerning the means and procedures used to achieve the required geographical distribution shall be described in the product literature for the equipment being evaluated and attested to in the application for equipment certification.

Other methods to satisfy the intent of the digital security code may be employed, subject to the approval of Industry Canada.

6 Transmitter and Receiver Standard Specifications

6.1 Type of Modulation and Access Protocol

Equipment certified under this standard shall use digital modulation.

In order to provide equitable access to the radio frequency spectrum, the licence-exempt PCS device must possess an access protocol. See Section 4.3.4.

6.2 Frequency Stability

The carrier frequency stability shall be maintained within ±10 ppm (±0.001%).

6.3 AC Power Line Conducted Emissions Limits

The limits of AC power line conducted emissions are given in RSS-Gen, Section 7.

6.4 Occupied Bandwidth

The occupied bandwidth shall not be less than 50 kHz nor more than 2.5 MHz.

6.5 Peak Transmit Power

Peak power shall not exceed 100 microwatts multiplied by the square root of the occupied bandwidth in hertz.

6.6 Power Spectral Density

The peak-hold power spectral density shall not exceed 12 milliwatts per any 3 kHz bandwidth.

As an alternative to the peak-hold power spectral density, the time-averaged power spectral density may be measured and it shall not exceed 3 milliwatts per any 3 kHz bandwidth.

6.7 Transmitter Unwanted Emissions

6.7.1 Emissions Outside the 1920-1930 MHz Band

Emissions outside the 1920-1930 MHz band shall be attenuated below a reference power of 112 milliwatts (-9.5 dBW) by at least:

• 30 dB between the band edges and 1.25 MHz above and below the band edges;
• 50 dB between 1.25 MHz and 2.5 MHz above or below the band edges; and
• 60 dB at 2.5 MHz or greater above or below the band edges.

6.7.2 Emissions Inside the 1920-1930 MHz Band

Emissions inside the 1920-1930 MHz band shall be attenuated below the transmit power permitted for that device, as follows:

• 30 dB between the frequencies 1B and 2B measured from the centre of the occupied bandwidth;
• 50 dB between the frequencies 2B and 3B measured from the centre of the occupied bandwidth; and
• 60 dB between the frequencies 3B and band edge,

where B is the occupied bandwidth in hertz.

6.8 Receiver Spurious Emissions

Receiver spurious emissions shall comply with the limits specified in RSS-Gen.
