RSS-139 Testing of Advanced Wireless Services Equipment

The wireless standard Canadian method evaluates transmitters used in radiocommunications systems. As a leader in RF regulatory compliance testing, Keystone Compliance recognizes the requirements needed for wireless radio manufacturers. Meeting the ETSI, FCC, and other wireless testing specifications can be challenging. Not only do we understand the challenges, but we help guide companies through the process.

Our proven process helps avoid product launch delays by inviting our clients to review draft reports before final certification. Keystone’s radio testing engineers streamline the process and assist companies to achieve the compliance they require. We tailor each test plan to individual customer needs minimizing unnecessary costs and over-testing.

Summary of RSS-139 Advanced Wireless Device Testing

RSS-139 tests advanced wireless services (AWS) equipment operating in the 1710 – 1780 and 2110 – 2180 MHz bands. This test sets out requirements for the certification of transmitters used in radiocommunication systems.

Equipment certified under this RSS Canadian wireless standard is classified as Category I equipment. A technical RSS intentional radiator acceptance certificate must be issued by a certification bureau or body. Like other Canadian RSS standards, RSS-139 is used in conjunction with RSS-Gen for general specifications and information relevant to applicable equipment.

Scope of Intentional Radiator AWS Equipment RSS-139

The RSS-139 transmitter power is measured in terms of a root-mean-square (RMS) average value. Equipment is tested for all channel bandwidths. The emission limits are measured with the carrier frequency set at both the highest and lowest settable frequencies permitted by the equipment.

Each transmitter must have a unique Mobile Equipment Identifier (MEID), or, International Mobile Equipment Identity (IMEI). This component is permanently attached to the main circuit board of the mobile transmitter. The integrity of the unit’s operating software is not alterable. The MEID or IMEI is factory set and also not alterable, transferable, removable, or otherwise to be manipulated.

The wireless RSS-139 Canadian devices can employ any type of modulation technique. However, whatever RSS technique is used must be reported. Mobile, portable, and fixed user equipment must operate only when under the control of a base station.

In addition, the peak to average power ratio (PAPR) of the equipment will not exceed 13 dB for more than 0.1% of the time, using a signal that corresponds to the highest PAPR during periods of continuous transmission. The first 1.0 MHz band will operate outside of the equipment’s smallest operating frequency block.

Lastly, mobile and portable equipment will employ a means for limiting power to the minimum necessary for successful communication. This equipment is only certified if it is capable of operating on all frequencies in the frequency range of 1710 – 1780 MHz and 2110 – 2180 MHz.
