EU Adaptivity Test Requirements (2.4GHz BLE) EN 300 328 V1.9.1 standard for 2.4GHz (BLE wide band modulation other than FHSS with non-LBT based DAA Mechanism) 1 Test standard: EN 300 328 V1.9.1 Note: *Transmit power below 10dBm EIRP does not require adaptivity test compliance. This test is 2 Injected AWGN compliance threshold: conducted AWGN -70dBm/MHz per chain applied to the BLE master as the one controlling the channel map. For example, BLE master is the one inquired and created the BLE connection with 3 Injected AWGN center frequency: Center at the channel frequency with 100% duty cycle the other companion device in BLUETOOL. 4 Injected AWGN bandwidth: Larger than operating channel bandwidth 5 Required traffic load: Minimum 30% 6 Required RSSI: -30dBm 2.4885GHz with -35dBm per chain shall be used for testing the Injected blocking signal frequencies to lowest operating channel 7 be added (single tone signal applied after AWGN signal injection started) 2.395GHz with -35dBm per chain shall be used for testing the highest operating channel 2.402GHz 8 Test channel/rate/mode 2.480GHz 9 Traffic stop Within 40msec None for non-LBT based wide band modulation other than 10 CCA time FHSS Allowed transmission with the AWGN Only short control signals are allowed with <10%* duty cycle 11 and blocking signals over 50ms observation period Broadcom Proprietary & Confidential. © 2009 Broadcom Corporation.

This test is applied to the BT master as the 2 Injected AWGN compliance threshold: conducted AWGN -70dBm/MHz per chain one controlling the channel map. For example, BT master is the one inquired and created the BT connection with the other 3 Injected AWGN center frequency: Center at the channel frequency with 100% duty cycle companion device in BLUETOOL. Larger than operating channel bandwidth (Must use 10MHz to 4 Injected AWGN bandwidth: block out more than 1 channel for SA measurement) 5 Required traffic load: Not defined 6 Required RSSI: -30dBm 2.4885GHz with -35dBm per chain shall be used for testing the Injected blocking signal frequencies to lowest operating channel 7 be added (single tone signal applied after AWGN signal injection started) 2.395GHz with -35dBm per chain shall be used for testing the highest operating channel FH 79 Channels at 2.402GHz (DH5) 8 Test channel/rate/mode FH 79 Channels at 2.480GHz (DH5) 9 Traffic stop (see next chart) 10 CCA time None for non-LBT based FHSS After N*COT=79*(3.75/2.9)*40msec~4.0sec, total transmissions after AWGN injected shall be <40msec. Allowed transmission with the AWGN After AWGN removed, traffic can resume only after 11 and blocking signals 5*N*COT=5*79*40msec=15.8sec silence period.
