Date : October 20, 2014 UNII Declaration Letter We have declared below featured for FCC equipment authorization, Device FCC ID: NKR-P75B (1) DFS Device -- Client with Radar detection capability , Client without radar detection capability (2) Active / Passive Scanning , Ad hoc mode access point capability Frequency Band Active Scanning passive scanning Ad Hoc Mode Access point (MHz) (the device can (where the device is capability capability transmit a probe can listen only with no (beacon)) probes) 5150 – 5250 Yes , No Yes , No Yes , No Yes , No 5250 – 5350 Yes , No Yes , No Yes , No Yes , No 5470 – 5725 Yes , No Yes , No Yes , No Yes , No 5725 – 5850 Yes , No Yes , No Yes , No Yes , No (3) Country code selection ability - Yes , No If no, pls explain how was implemented : (4) Meet 15.202 requirement - Yes , No , pls check below : A client device is defined as a device operating in a mode in which the transmissions of the device are under control of the master. A device in client mode is not able to initiate a network. (5) For client devices that have software configuration control to operate in different modes (active scanning in some and passive scanning in others) in different bands (devices with multiple equipment classes or those that operate on non-DFS frequencies) or modular devices which configure the modes of operations through software, the application must provide software and operations description on how the software and / or hardware is implemented to ensure that proper operations modes can not be modified by end user or an installer. Apply , No Apply , (If apply , pls help to provide explanation on how it was implement (By hardware or software , and how software was controlled) On DFS channels, the WLAN driver on the device operates under the control of an AP at all times, except when in ad-hoc mode, on US non-DFS channels.
