DENso DENSO WAVE DFS chent dev1ce channel plan and software operatlonal declaration | Date 2018 12—06 We, DENSO WAVE INCORPORATED 'declare that the device, FCC ID: PZWB'HT1 700QG, Model Name: BHT—1700QGWBG—1, BHT—1700QWBG—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 Th1$ 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 i _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 40 .44 | 48 52 56 60 64 Frequency (MHz) 5180 5200 5220 ; 5240 5260 5280 5300 5320 Scan Type Passive Passive Passive Passive Passive Passive Passive Passive : > CH . 100 104 108 °; 112 116 120 124 128 132 136 | 140 Frequency (MHz) 5500 5520 5540 5560 5580 5600 5620 : 5640 5660 5680 5700 Scan Type _ |Passive Passive Passive Passive Passive Passive Passive Passive Passive Passive Passive ch CC 044| 49 | 153 157 161 165 Frequency (MHz)| 5720 5745 5765 5785 : 5805 5825 Scan Type Active ‘Active {Active ‘Active ‘Active Active ; Also, on DFS channels, the WLAN driver in the dev1ce 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 firmwareis protected by special signature and CRC checksum. Signature and > CRC checksum will be calculated and verified before firmware upgrade. Unauthorized modification to firmwarewill lead the failure of verification, thus firmware upgrade is not allowed.
