So, setting up the outside unit where the signal is the strongest will provide the best results. 1. Working Principle： Outside Signal: Outdoor Antenna Gain: The gain of outdoor antenna Outdoor Cable Loss: The loss of the outdoor cable Booster Gain: The actual working gain of the booster Indoor Cable Loss: The loss of the indoor cable Indoor Antenna Gain: The gain of indoor antenna Receive the signal from the outdoor base station signal tower HOW IT WORKS outside signal Base Station outdoor calbeboosterindoor antennaoutside antenna Signal transmission loss and power level Distance of separation between the outdoor unit and the indoor unit.2. Please make sure the horizontal distance between outdoor antenna and indoor antenna is more than 6 meters(20ft);The vertical distance between indoor antenna and outdoor antenna is more than 3 meters(10ft) 3. Tips:The user guide is focused on: 1. Getting the best outside signal. 2. Keeping the maximum booster gain. For example: -65dBm + 6dBi - 5dB + 70dB - 3dB + 6dBi = 9dBm (System Output Power) Note: FCC regulations limit the amplification of all cell phone boosters in order to prevent damage to the telecommunications infrastructure. Therefore, the maximum coverage area of a booster depends on the original power level of the signal captured by the outdoor unit. Notice: Not recommended when outdoor signal strength is less than -110dbm (3G/lx) or -120dBm(4G/LTE). The resulting coverage area of the boosted signal will be prohibitively small. Find your cell tower nearby! There are a variety of resources available online, here is a third party website recommended. Use it to locate your nearest cell tower: www.cellmapper.net Preparation Coverage area ability Visit website www.cellmapper.net Step 1. Power Level at the outdoor antenna location Strong(4~5 bars on the cellphone) Coverage Area (sq.ft) Medium(3~4 bars on the cellphone) Weak(1~2 bars on the cellphone) 2,500 1,000 300 Select Provider. You will find the cell tower around your house. Step 3. Find your location on the map and zoom in on your area Step 2. Click the red or green dot on the map that represents the base station, and the detailed information of the base station will be displayed. The first important information, you can see from the above four pictures, the coverage area (shaded part) of each base station is different. You have to find a base station with signal coverage to your house, or the coverage direction is facing you, and the coverage area is closest to you. The second important information, you can scroll the information content on the right to find the specific carrier information of this base station, including the communication standard and frequency band. Please reference the right picture, "LTE〃 and "B2 FDD'(Band 2, FDD). Find your cell tower Step 4. How to choose the right booster before purchase? For iPhone - Please dial *3001#12345#* → Press call button → Click 'Serving Cell Info' → Check 'Freq Band Indicator'. For Android - Please download 'LTE Discovery' APP →Click ‘SIGNALS’ → Check ‘EARFCN’.

Conducted Spurious Emission Applicable Standard According to § 2.1051 Spurious emissions at antenna terminals: The power of any emission outside a licensee’s frequency block shall be attenuated below the transmitter power (P) by at least 43 + 10 log10(P) dB. So the Conducted emissions limit = -13 dBm Test Procedure According to section 7.6 of KDB 935210 D03 Signal Booster Measurement v04r04: The following procedures shall be used to demonstrate compliance to the applicable conducted spurious emissions limits as per Section 2.1051. NOTE–For frequencies below 1 GHz, an RBW of 1 MHz may be used in a preliminary measurement. If non-compliant emissions are detected, a final measurement shall be made with a 100 kHz RBW. Additionally, a peak detector may also be used for the preliminary measurement. If non-compliant emissions are detected then a final measurement of these emissions shall be made with the power averaging (rms) detector. a) Connect the EUT to the test equipment as shown in Figure 1. Begin with the uplink output (donor) port connected to the spectrum analyzer. b) Configure the signal generator for AWGN with a 99% OBW of 4.1 MHz, with a center frequency corresponding to the center of the CMRS band under test. c) Set the signal generator amplitude to the level determined in the power measurement procedure in 7.2. d) Turn on the signal generator RF output and measure the spurious emission power levels with an appropriate measuring instrument as follows. 1) Set RBW = measurement bandwidth specified in the applicable rule section for the operational frequency band under consideration (see Appendix A for relevant cross-references). Note that many of the individual rule sections permit the use of a narrower RBW [typically ≥ 1% of the emission bandwidth (EBW)] to enhance measurement accuracy, but the result must then be integrated over the specified measurement bandwidth. 2) Set VBW = 3 RBW. 3) Select the power averaging (rms) detector. (See above note regarding the use of a peak detector for preliminary measurements.) 4) Sweep time = auto-couple. 5) Set the analyzer start frequency to the lowest radio frequency signal generated in the equipment, without going below 9 kHz, and the stop frequency to the lower band/block edge frequency minus 100 kHz or 1 MHz, as specified in the applicable rule part. Note that the number of measurement points in each sweep …
