DFS client device channel plan and software operational declaration Date: 2018-12-20 We, DENSO WAVE INCORPORATED declare that the device, FCC ID: PZWBHT1800QG, Model Name:, BHT-1800QWBG-3, BHT-1800QWBG-1, BHT-1800QWBG-2, does not have “Ad Hoc on non-US frequencies” and/or “on DFS frequencies. Also, the client software and associated drivers will not initiate any transmission on DFS frequencies without initiation by a master. This includes restriction on transmissions for beacons and support for ad-hoc peer-to-peer modes. Below is the channel / frequency plan for the device CH 1 2 3 4 5 6 7 8 9 10 11 Frequency (MHz) 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 Scan Type Active Active Active Active Active Active Active Active Active Active Active CH 36 38 40 44 46 48 52 54 56 60 62 64 Frequency (MHz) 5180 5190 5200 5220 5230 5240 5260 5270 5280 5300 5310 5320 Scan Type Passive Passive Passive Passive Passive Passive Passive Passive Passive Passive Passive Passive CH 100 102 104 108 110 112 116 118 120 124 126 Frequency (MHz) 5500 5510 5520 5540 5550 5560 5580 5590 5600 5620 5630 Scan Type Passive Passive Passive Passive Passive Passive Passive Passive Passive Passive Passive 128 132 134 136 140 5640 5660 5670 5680 5700 Passive Passive Passive Passive Passive CH 149 151 153 157 159 161 165 Frequency (MHz) 5745 5755 5765 5785 5795 5805 5825 Scan Type Active Active Active Active Active Active Active Also, on DFS channels, the WLAN driver in the device operates under the control of an AP at all times, except when in ad-hoc mode, on US non-DFS channels. The device passively scans DFS frequencies until a master device is detected. The control of this functionality is not accessible to anyone under any conditions. Furthermore, the firmware is protected by special signature and CRC checksum. Signature and CRC checksum will be calculated and verified before firmware upgrade. Unauthorized modification to firmware will lead the failure of verification thus firmware upgrade is not allowed.
