EN 50131-5-3 Grade 3 implementation in CC1310

Other Parts Discussed in Thread: CC1310

Hi

According to EN 50131-5-3 standard , in order to meet Grade 3 Sub 1GHz security system it needs Transceiver with Dual band support (like 868 and 433 MHz).Right?

The questions about Dual band implementation in CC1310 is as follow:

  1. Does CC1310 meet EN 50131-5-3 Grade 3? What needs for that?
  2. Could CC1310  transmit & receiving in two separate bands such as 868 and 433  to  overcoming the interfering signals (Immunity to interference section 4.4 of EN 50131-5-3 ------> 10v/m)?
  3. Which selectivity required from our line up receiver (external SAW filter) to meet immunity to interference requirement 10v/m?

Regards

  • One more issue:
    Our dual band line up based on CC130 + Wideband Balun + Harmonic filters that switch according to band working 868/433 MHz.
    Is there any issue to switch between two bands to meet EN 50131-5-3 section 4.5? Timing?
  • Roni,

    We have no experience with EN 50131 so don't know if CC1310 will be grade-3 compliant. An interfering signal at 10 V/m @868 MHz corresponds to approx 4 dBm. I have no idea what PHY parameters you are using or how EN 50131 defines the immunity testing , but a SAW filter will be needed to meet immunity requirements.

    If you send the finer details of the standard we might be able to provide a more thorough answer. (I believe you know my personal e-mail address so if the standard cannot be shared here you can send it to me directly).

    Best regards,
    Sverre
