SUBJECT: LG Electronics USA FCC ID : NZFP880G Channel plan and software operational info * Question1. Submit a channel/frequency plan for this device showing the channels that have active scanning or passive scanning. Actives scanning is where the device can transmit a probe(beacon) and passive scanning is where the device is can listen only with no probes. 1. Active scan on: 2412~2462MHz, 5180~5240MHz(Non DFS frequency), 5745~5825MHz 1) Channels 1~11 (2412~2462MHz) 802.b/g/n (not support 40MHz Channel) 2) Channel 36~48 (5180~5240MHz) 802.11 a/n (not support 40MHz Channel) 3) Channel 149~165 (5745~5825MHz) 802.11 a/n (not support 40MHz Channel) 2. Passive scan on: 5260~5320MHz(On DFS frequency), 5500~5700MHz(On DFS frequency) 1) Channel 52~64 (5260~5320MHz) 802.11 a/n (not support 40MHz Channel) 2) Channel 100~140 (5500~5700MHz) 802.11 a/n (not support 40MHz Channel) But Channel 120~128 (5600~5650MHz) are not support. *Detail Table *2.4GHz Band WLAN Active Passive Client Radar freq.

If the manual is not complete, upload an updated User’s Manual exhibit. ☞ Please see attached user manual. * Question 4 Can this device act as an access point on the non DFS legacy frequencies(5.15~5.25GHz) ☞ No, This device does not act as an access point at 5G band. * Question 5 Verify that this device meets the frequency requirements of Section 15.202 ☞ Yes, Please refer answer of Question1.

* Question 6 For client devices that have software configuration control to operate in different modes(active scanning in some and passive scanning in others) indifferent 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. ☞ On DFS channels, the WLAN subsystem operates under the control of an AP at all times. 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 and peer-to-peer modes. This device software is set in non-volatile memory. Only LG engineer can access this SW because this SW is cryptographic code that only access through a password. Therefore this device will not allow the user settings to select any non-US frequency and will not be accessible and cannot be changed by the end user or by host configuration setting.
