3. than 30 to correctly select the donor BTS 4 There is large physical separation between the antennas in order to prevent degradation of signal quality and risk of oscillation Antenna isolation Ways to achieve this can be usage of highly directional antennas with good front to back interference ratio or external shielding between the antennas For example your building has a metal roof and you install the Donor antenna above the roof and the Coverage antenna below the roof Another option is to use a Frequency Translating Repeater or ICS repeater 5 1 Minimum Signal Levels You must have a minimum signal level in the place where you would install the Donor antenna Failure to provide sufficient input signal will only result in a poor coverage inside the building for this repeater system 5 2 Howto check your signal levels To check your signal levels use the phone in the place where antenna be install on the roof and observe the signal bars on the phone It is also helpful to be on a call for immediate registration of the signal reception Carefully walk around the roof with the phone to see where the signal is best The Donor outside antenna should be placed in the location where you get the most signal 5 Bars 4 Bars 3 Bars 2 Bars 1 Bars Tall Tall Tall Tull Teall NOKIA NONE gt 85dBm 85 90dBm 90 95dBm 95 100dBm Anycall gt 85dBm 85 90dBm 90 95dBm 95 100dBm__ 100 105dBm Motorola gt 80dBm 80 90dB

6. nna 2 Linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak blind coverage area 3 And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction It is commonly used in the area there are two type of mobile network such as GSM CDMA GSM DCS and GSM UMTS It will reduce site deployment cost by using one dual band donor antenna one dual band service antenna and dual band repeaters in one enclosure It is applied to small medium size areas such as offices shops basements and remote countryside etc This model booster is commonly used in situations where large numbers of frequency carriers are to be repeated or when base station synthesized frequency hopping is used This model booster does not separate out specific carriers but amplify and retransmit all signals within a defined frequency band Inter modulation distortion caused by band selective repeaters usually means that lower output power per carrier can be realized compared to channel selective repeaters 2 Technical Specifications Network Customized Uplink Gain Downlink Uplink Output Power Downlink Gain Adjust Scope Gain Adjust Step Gain Adjust precision Band Ripple ALC Scope Frequency Error I O Impedance VSWR Noise figure Spurious Emission IM3 Delay Max Input Power Level 1minute RF Connector Temperature Range Relative humidity Po
7. tion 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 maintenance and operation for this product Repeater amplifies BTS uplink and downlink signal it can extend BTS coverage area in downlink but also effect BTS receive sensitivities in uplink 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 The power adaptor output is 5Vdc 4A please use right adaptor 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 Installing a repeater system is really quite simple The most difficult task in installing the system is running t
