Federal Communication Commission Equipment Authorization Division, Application Processing Branch 7435 Oakland Mills Road Columbia, MD 21048 UNII Device Declaration Letter To whom it may concern: We have declared below featured for FCC equipment authorization, Device FCC ID: U4GJNGW (1) DFS Device:  Master  Client with Radar detection capability  N/A  Client without radar detection capability, (2) Active / Passive Scanning , adhoc mode access point capability Frequency Band Active Scanning* (the Passive scanning** Ad Hoc Mode Access point (MHz) device can transmit a (where the device is Capability capability probe (beacon)) can listen only with no probes) 2412-2462  Yes  No  Yes  No  Yes  No  Yes  No 5745-5825  Yes  No  Yes  No  Yes  No  Yes  No 5755-5795  Yes  No  Yes  No  Yes  No  Yes  No 5180-5240  Yes  No  Yes  No  Yes  No  Yes  No 5190-5230  Yes  No  Yes  No  Yes  No  Yes  No 5260-5320  Yes  No  Yes  No  Yes  No  Yes  No 5270-5310  Yes  No  Yes  No  Yes  No  Yes  No 5500-5700  Yes  No  Yes  No  Yes  No  Yes  No 5510-5670  Yes  No  Yes  No  Yes  No  Yes  No * Passive Scanning – No for 2.4GHz, Yes for all 5GHz 20MHz channels, unless Country Code is established. Once Country Code is established , some bands go Active depending on Country Code selection (see also Regulatory Domain Management document). ** Active Scanning – Yes for 2.4GHz, No for all 5GHz 20MHz channels unless Country Code is established. Once Country Code is established , some bands go Active depending on Country Code selection (see also Regulatory Domain Management document). (3) Country code selection ability  Yes  No If no, pls explain how it was implemented: Country code firmware cannot be modified or selected by the end-user. Country code selection is based on information provided by the AP. (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 can not be modified by end user or an installer.  Apply  Does not apply (If apply, pls help to provide explanation on it was implement, and how software was controlled) Country code firmware cannot be modified or selected by the end-user. Country code selection is based on information provided by the AP (see also SOFTWARE SECURITY FOR U-NII DEVICES document)
