CC2530-CC2592EM-RD: CE certification: the adaptivity test

Hi, 

if CC2530/CC2592 runing Zigbee needs to pass the 4.3.2.6 Adaptivity (adaptive equipment using modulations other than FHSS)?

if CC2530 supports the CCA/LBT in default?

    Hi Albin,

    Zigbee must be certified as "wide band modulation" and is limited to 10 dBm in Europe.

    Hi Fredrik,

    From the CE test for 2.4GHz in EN300328 test specification, we can find a session talk about the Adaptivity.

    4.3.2.6 Adaptivity (adaptive equipment using modulations other than FHSS)

    From my understanding on Zigbee, it supports CSMA/CA in default mode, it means the RF will use CCA to listen the channel before Tx.

    If the CCA value is greater than the setting value, the TX will try after a certain time back off.

    So I think it is similar function as the Adaptivity mentioned in Test Spec, which means customer can set the Tx power big than +10dBm if they can pass the Adaptivity test.

    Please double check it.

    Thanks.
