Date: 2018/09/04 DTS-UNII Device Declaration Letter To whom it may concern: We have declared below featured for FCC equipment authorization, Device FCC ID: HFS-C302U (1) DFS Device -- Master , Client with Radar detection capability , Client without radar detection capability, N/A (2) Active / Passive Scanning Frequency Band Active Scanning passive scanning (MHz) (the device can (where the device is transmit a probe can listen only with (beacon)) no probes) 2412 - 2462MHz Yes , No Yes , No 5150 - 5250MHz Yes , No Yes , No 5250 - 5350MHz Yes , No Yes , No 5470 - 5725MHz Yes , No Yes , No 5725 - 5850MHz Yes , No Yes , No (3) Country code selection ability - Yes , No If yes, pls explain how it was implemented : (pls also help to provide detail of options for each country selection) (4) Meet 15.202 requirement - Yes , No , pls check below : A master device is defined as a device operating in a mode in which it has the capability to transmit without receiving an enabling signal. In this mode it is able to select a channel and initiate a network by sending enabling signals to other devices 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 cannot be modified by end user or an installer. Apply , “Yes , please see SW security Description”. No Apply, (If apply , pls help to provide explanation on it was implement , and how software was controlled) (6) Please help to provide justification how device was restricted to operate in 5600-5650MHz in below. This device operates as a client without radar detection capability and will be programmed at the factory to passively scan on the following dynamic frequency selection (DFS) channels and will only listen for a master device and cannot sent a probe request to initiate communication on these DFS channels, accordingly passive scanning provides protection for TDWR operations and preventing transmission in the 5600MHz-5650MHz.
