3.1 New SRRC rules and applicable terms

A requirement for a yielding mechanism for 2.4GHz Bluetooth device is added to the latest specification issued by State Radio Regulatory Commission (SRRC), the Ministry of Industry and Information Technology, titled Technical Requirements for Interference Avoidance in Radio Transmitter Equipment in 2400MHz, 5100MHz and 5800MHz Bands. This requires Bluetooth devices to support Adaptive Frequency Hopping (AFH). AFH is not yet supported in versions prior to SDK8.30. In that case, users may choose equipment that complies with the requirements for Class 4: interference mitigation technologies based on other mechanisms. This item is required to meet an “equivalent utilization” of no greater than 10%.

In the formula, EU is the equivalent utilization and DC is the device duty cycle, where Plimit is the equivalent isotropic radiated power limit at 2400MHz or 5800MHz in the corresponding Annex 1.

Plimit is 100mW for antenna direction gain less than 10dBi.

For devices with an e.i.r.p. of 10dBm (10mW) or less (8dBm for CC2340 series and 5dBm for CC2642 series), assuming that a maximum antenna direction gain is 0dBi, EU will be less than 10% even if the duty cycle is 100%.

In the latest SDK versions (such as SDK9.x and later), devices that claim to be based on the “detection and avoidance” mechanism no longer need to consider the duty cycle.
