RSS-210 – Licence-exempt Radio Apparatus (All Frequency Bands): Category I Equipment

Annex 5 – Radio Frequency Identification (RFID) Devices in the Band 433.5–434.5 MHz

The provisions of this annex are for RFID devices used to identify the contents of commercial shipping containers. Operation must be limited to commercial and industrial areas such as ports, rail terminals and warehouses. Two-way operation is permitted to interrogate and to load data into devices. Voice communication is prohibited.

Devices approved under this annex shall comply with the following:

  1. Devices shall be provided with a means for automatically limiting operation so that the duration of each transmission shall not be greater than 60 seconds and be permitted only to reinitiate an interrogation in the case of transmission error. Under normal circumstances (no transmission error), the silent period between transmissions shall not be less than 10 seconds.
  2. The field strength of any emissions radiated within the band 433.5–434.5 MHz shall not exceed 11,000 microvolts/m measured at 3 metres with an average detector. The peak level of any emission within this specified frequency band shall not exceed 55,000 microvolts/m measured at 3 metres. Outside this specified band, the general field strength limits listed in RSS-Gen apply.

A6.1.2 Emission Types and Modulation Requirements

Only emission types F3E, F1D and F2D are permitted for FRS.

Non-voice emission is permitted only for selective calling or tone-operated squelch to establish or continue a voice communication, digital data transmission of location information or text messaging, and is subject to the following restrictions:

  1. An FRS unit may transmit tones to make contact or to continue communications with a particular FRS unit. If the tone is audible (greater than 300 Hz), it may be transmitted continuously no longer than 15 seconds at a time. If the tone is inaudible (300 Hz or less), it may be transmitted continuously only while the user is talking.
  2. The FRS unit may transmit digital data containing location information, or requesting location information from one or more other FRS units, or containing a brief text message to another specific FRS unit. Digital data transmissions must be initiated by a manual action or command of the user. However, an FRS unit receiving an interrogation request may automatically respond with its location. Digital data transmissions shall not exceed 1 second, and shall be limited to one transmission within a 30-second period. However, an FRS unit may automatically respond to more than one interrogation request received within a 30-second period.

  2. 35 dB, measured with a bandwidth of 300 Hz, in the band 12.5 kHz to 31.25 kHz removed from the channel centre frequency; and
  3. 43 dB + 10 log10 (carrier power in watts) dB, measured with a bandwidth of at least 30 kHz for frequencies beyond 31.25 kHz removed from the channel centre frequency.
