YETCELFI-RS240WUCel-Fi Residential System

Congratulations on your new indoor signal solution. This Cel-Fi system is designed to provide you with significant improvements in coverage as well as 3G data rates. Setting up the system is extremely simple and consists of placing and plugging in two components; a Window Unit and a Coverage Unit. By spending just a few minutes using the instructions in this guide, you can optimize the installation and get the very most from your new Cel-Fi System. If you have any trouble during setup, please use the trouble shooting steps included in this guide. In the package you will find: Window Unit Coverage Unit Two power adapters. CEL - FIRS 2 Quick Start Guide Step 1 Find the spot with the best 3G coverage: The first step in setting up your Cel-Fi system is to find the spot in your home or office that has the best 3G coverage. This is typically by a window, and if you are in a multi-story building, upstairs windows are usually better than downstairs windows. Step 2 Plug in the Window Unit: Take the Window Unit and one power supply out of the box (both power supplies are the same, so grab either one). Plug the Window Unit in, and check to make sure that you can see at least 1 “Bar” on the display in the center of the device. If you do not see at least 1 bar, try a different location. NEED HELP?

W I N D O W U N I T W I N D O W U N I T C O V E R A G E U N I T COVERAGE UNI T CEL - FIRS 2 Trouble Shooting TOO CLOSE A zero on the numeric display indicates that the “Coverage Unit” needs to be moved farther away from the “Window Unit”. GOOD This green icon indicates that the “Coverage Unit” is functioning normally. TOO FAR This red icon indicates that the “Coverage Unit” needs to be moved closer to the “Window Unit”. Step 3 Optimize the Window Unit Placement The number of bars you can see on the Window Unit make a significant difference in the operation of the Cel-Fi system. Try moving the Window Unit to a couple of different spots to see if you can get better signal; the more bars the better. Step 5 Optimize The Coverage Unit Placement The farther away you place the coverage unit from the Window unit the better the coverage in your home, so put the Coverage Unit as far away from the Window Unit as possible. The number shown on the side of the display gives you an indication as to the quality of the placement. Test two or three locations and for best results; try and get a 7, 8 or 9 on the display. Indicator No lights on “Window Unit” display. Status indicator is flashing green for mo re than a minute. Status indicator is flashing red. Status indicator is on solid red. No se gment lit on signal display and status indicator on solid green. Problem There is no power. The “Window Unit” unit is attempting to complete regulatory compliance. Error Code on ”Coverage Unit”. Ha rdware Error. Not receiving cell signal. Try This 1. Is the unit plugged in? 2. Is the re power at the outlet? 3. Try exchanging the power supplies with the “Coverage Unit” to see if the power supply is defective. 1. Wait for the status indicator to stop flashing, this could take several minutes. 1. See the “Coverage Unit” to determine what error code is being displayed. 1. Try resetting the “Window Unit” by unplugging it and then plugging it back in. 2. If problem persists return system for service/replacement. 1. Try moving the “Window Unit” to another room or area where you have more coverage. (Use your cell phone to find the best 3G coverage). Indicator E1 E3 E4 Problem No Signal on “Window Unit”. ”Coverage Unit” is overheating. “Window Unit” is overheating. Try This Try moving the “Window Unit” to another room or area where you have coverage. (Use your cell phone to find the best 3G coverage). Make sure that the vents on the unit are not blocked.

Page 1 of 4 Federal Communications Commission January 13, 2011 RE: FCC ID: YETCELFI-RS240WU Form 731 Confirmation #: EA272711 Correspondence Reference Number: 40891 Attention: Jyun-Cheng Chen Please find our response to your questions on this application below in blue: 1. The application form is still incomplete as of today. Please check your requested frequency range listing. The device is certainly operating in more than the 5150- 5250 MHz band requested on the Form 731. In addition, please confirm the two changes I made for you: Part 27 Emission Designator (per your request) and the related FCC ID on the Part 15 application form (Equip. Specs. 2). The latter had mistakenly listed itself as a related FCC ID, causing the system to show error message whenever trying to save the application. Let me know if both changes are acceptable to you. You are correct. A second line entry with a frequency range of 5268-5303 MHz with output power of 0.054W and Part 15E should have been included on the form. The change to the Part 27 Emissions Designator and the related FCC ID on the Part 15 application are acceptable. 2. The e-mail from NTIA is acceptable. Noted 3. Please check Page 2 of the MPE calculation. It clearly states that the MPE calculations are based on only 1 WCDMA channel instead of 3. In addition, please clarify if the UNII band transmission does include the payload (i.e., the 4 WCDMA channels) plus the two OFDM control channels. The MPE report seems to indicate only 1 OFDM channel is used in the MPE calculations. A total of 6 channels are carried on the WU-to-CU link according to the Theory of Operation. The listed power values for the calculation includes the 3 WCDMA “sub” channels, so the calculated MPE values are correct. For the OFDM link, the listed power includes the 6 “sub” channels. We listed it as one channel that included all sub channels. A revised MPE calculation exhibit has been uploaded with an explanation of this. 4. Page 35 of FCC 06-96 states that "For master devices, indicate how the master provides, on aggregate, uniform channel loading of the spectrum across all channels." Therefore, it is the loading/usage that needs to be uniform in order to "avoid dense clusters of devices operating on the same channel" (Page 2 of FCC 06-96). The description in the Theory of Operation appears to indicate that while Page 2 of 4 the initial channel selection is random, the selected channel would be occupied until power cycle or a radar signal is detected. For a cellular network access device, power cycle is a rare event. Please justify the current design meets the above uniform channel spreading rule. The operation in Cel-Fi is as follows: a) Each Cel-Fi at power up performs random (with uniform distribution) selection of channels to operate on. On the two selected channels CAC is performed. If they are radar-clear channels, the channels are selected for operation. If one or both are not radar –free, then random selection is repeated until two radar-clear channels are found. During operation ISM is done continuously on them. If radar is detected, the channel is vacated and once again a new channel is picked randomly (with uniform distribution over the remaining channels). This is also true if the units are power cycled. Coming out of a power cycle – channel selection is once again random b) It is true that this procedure can result in a channel being occupied for long durations. However, this behavior is no different that DFS/ Radar compliant 802.11n devices. These devices, as Cel-Fi, adhere to the spirit of the standard and select their channels randomly with a uniform distribution. Once selected, any one access point stays on the same channel for a prolonged time. c) However, that said, the intent of FCC 06-96 is indeed valid and is fully met in letter and in spirit by Cel-Fi. If 100 Cel-Fis are powered on – each does the channel selection procedure independently and randomly (over a uniform distribution over available channels) and over the ensemble (of Cel-Fis) the channels occupied would be uniformly spread and there would not be dense- clustering onto any one given channel. This pattern of behavior and uniform loading over the ensemble will continue as the normal asynchronous time events (such as power cycling) occur over time. d) Again – the way 802.11n AP meet this specification is identical – i.e. over an ensemble the distribution of occupied channels is uniform while any given AP stays on its channel for significant durations 5. The objective of the network closed loop power control is actually to balance signals received from various UEs separated by the orthogonal spreading codes. Therefore, the power level is not necessary the minimum required to maintain the link quality. The design seems to provide a fixed repeater gain and thus basically follow the network power control. This is not truly the ATPC required by 27.50(d)(4). Could the applicant elaborate further on its claim of compliance? Two issues are worth clarifying: a) The first is that since Cel-Fi is a bi-directional repeater. It provides fixed gain in either direction that enhances coverage while staying unconditionally stable. The gain in both directions is the same – so that Cel-Fi does not interfere with the macro Network’s link balancing etc. As such, Cel-Fi is not involved in the power control on the cellular link. b) That said, however, the cellular networks power control does indeed control the power of each user to the minimum power necessary. The comment above Page 3 of 4 is indeed correct as applied to the uplink of the cellular link. However, the power control algorithm in WCDMA serves two purposes i. Equalizing received power at the NodeB input (as mentioned above). This mitigates near-far problems and makes sure all users can close their links regardless of distance from the NodeB so long as the UE have power to do so ii. Keeping the NodeB Rise-Over-Thermal (RoT) to the lowest given these set of u…

Verified and confirmed. 2) Your arguments on ATPC and uniform channel usage are acceptable. a. Noted 3) The confidentiality request letter asks for BOMs, however the parts list and tune- up procedure exhibit currently is empty with the NII filing (complete with the TNB filing). a. We have uploaded the parts list and tune up procedure exhibits for the Part 15 filing. Please note it was our understanding, based on section 2.1033(b) of the FCC rules that these items are not required for a Part 11, 15 or 18 filing which is why they were not uploaded originally with this filing. They were uploaded with the part 27 filing per section 2.1033(c) and thus the request that they be held confidential. 4) Please add RF exposure warning message (separation distance) in the user's manual. Both uplink and downlink should be considered active at the same time when suggesting such a distance in the manual. a. A revised user manual with the RF exposure warning has been uploaded (refer to file “420N003-002-001-10R51_FCCpending.pdf”) Regards, David W. Bare Chief Engineer DWB/dmg
