Step 7 Power up the system and check for signal inside the building If needed tune system by moving and or pointing the Donor and Coverage antennas until get the most signal possible Step 8 Secure all antennas and cables securely mount the repeater and clean up the installation 6 3 Commissioning Connect to Donor antenna Receive BTS signal source We Connect to Service antenna Retransmitted signal to target coverage area PWR Power Supply Indicator Show Power Supply Status Repeater Working Status Show Repeater Working Status Bar Signal Strength Indicator Show Repeater output power strenght The repeater work in indoor the indoor condition should meet environment requirement such as temperature waterproof installation space and interference source In order to receive right BTS signal the antenna be directly toward to visual BTS RF connectors should be link tighten Use mobile signal bars to check coverage effect on site For dual band repeater if one band signal is not well you can change the donor antenna direction and check the change until it reach good coverage For dual band repeater the donor antenna direction must be adjustment angle by angle so the dual band input power require good signal at the same time then dual band repeater can work with maximum coverage area and distance
3. from the base station is received via directly antenna then forwarded through a duplex filter is amplified in a low noise amplifier LNA enters the RF filter for wideband selective and then amplified in the power amplifier The output signal passes a duplex filter before it is fed to mobile or indoor antenna which retransmits the signal to the aim areas 5 Applications Example bw Donor Antenna Tanl 5 Bars gt 75dBm Repeater ERIP Loss2 Power Power GC Service Antenna RSSI Min Reception Signal Level Donor Antenna Gain 1 Input Power RSSI Loss1 2 Output Power Input Power Repeater Gain 3 ERIP Output Power Loss2 Service Antenna Gain 4 5 1 Minimum Signal Levels It requires a minimum signal level in the place where install the donor antenna Failure to provide sufficient input signal will only result in a poor coverage inside the building for this repeater system To check signal levels use the phones in the place where antenna be install on the roof and observe the signal bars on the phone The Donor outside antenna should be placed in the location where you get the most signal Tull Lat Tull Tall Tull 5 Bars 4 Bars 3 Bars 2 Bars 1 Bars gt 75dBm gt 80dBm gt 85dBm gt 90dBm gt 95dBm Notices 1 The donor antenna should have line of sight LOS with the BTS antenna If the signal strength is adequate LOS may in some cases not be necessary 2 Dono
4. ce and operation for this product BS and MS port must be connected to donor antenna and service antenna when powers supply on otherwise the equipment will be damage for long term use When use repeater for outdoor the distance between donor antenna and service antenna must be gt 20metes otherwise the repeater will be damage because isolation problem for long term use Donor antenna need to be lighting proof and lighting rod need to be install for donor antenna installation pole outside Check input power require input power less than maximum input power of repeater otherwise the repeater cannot work well Keep clear for label and indicator on surface of repeater to be identified 6 2 Installation Step 1 Start by taking phone up to the roof or other location outside to find where the signal is strongest Step 2 Temporarily mount the Donor outside antenna in that location It may need to adjust and move the antenna later Step 3 Run coaxial cable into the building to a convenient location where you can also get standard 220VAC power for the repeater Step 4 Place the repeater in that location and connect the coaxial cable to the Donor Side of the repeater and the donor antenna Step 5 Mount coverage inside antenna in a productive location It may need to adjust or move the antenna later Step 6 Connect coaxial cable between the coverage antenna and the repeater output port

6. r antenna gains are typically 9 to 14 dB and have a horizontal and vertical beam width of less than 30 to correctly select the donor BTS 5 2 Custom Applications If building is made of concrete steel steel roof copper roof brick aluminum siding concrete roofing tiles metal roofing tiles or any other signal stopping material a repeater is usually the ideal solution for your situation Donor antenna Most homes or buildings are easily covered by one repeater systems Some buildings are larger or have multiple areas inside that need coverage 4 Donor Antenna Service Antenna Repeater Splitter It may need longer cables more than 2 coverage antennas or other items in order to fully cover your building We can make almost any cable length and can help design a system that fits your application 5 3 Isolation and Separation Isolation refers to the proper distance or separation needed to keep the Donor antenna signal pattern and the Coverage antenna signal pattern away from each other Isolation becomes particularly problematic when Omni directional antennas are used for both the Donor and the Coverage antennas Since these antennas transmit in a circle or more accurately a sphere it is very easy for these spheres to overlap and thus negate the repeater system 6 Production Operation 6 1 Notices Follow below safety items carefully before installation implementation maintenan
