ALLGON System ABAR Repeaters & OMTIntroduction Introduction Allgon repeaters are used to fill out uncovered areas in cellular mobile systems, such as base station fringe areas, road tunnels, busirEss and industrial buildings, etc. A repeater receives signals from a base station, amplifies and retransmits the signals to mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously. To be able to receive and transmit signals in both directions, the repeater is connected to a donor antenna directed towards the base station and to a service antenna directed towards the area to be covered. Operation of the repeaters is performed using a desktop or notebook and the Allgon OMT (Operation & Maintenance Terminal) which communicate, locally or remotely via modem, with the repeaters. There is also an Allgon OMC (Operation & Maintenance Center), which is intended to be used to run many Allgon AR repeaters. The repeaters and the OMIT is described in this manual. The OMC is described in the Advanced Repeater 0MG, User’s Manual. User’s Manua~ VD2O1 17/ENRev. 4B 19c8-032-1 Figure 2-1. Allgon AR Repeater InstallationAR Repeaters & OMTALLGON System AB Installing 24 Volt or 48 Volt DC Power Supply Unit You can replace an AC PSU with a 24 Volt or 48 Volt DC PSU as follows: 1.Switch the repeater off and remove the mains plug from the PSU, if not already done (1 in Figure 3-9). 2.Disconnect the two connectors on the PSU. 3.Loosen the three fixing screws using a 5mm Allen key. 4.Remove the PSU from the repeater. 5.Mount the 24/48 Volt DC PSU with the three fixing screws (3). 6.Connect the PSU to the DIA board (2). 7.Connect the DC power cable. The supplied cable has a radiation limiter which is a requirement for the 24/48 Volt unit to be type approved. The cable shall be connected as follows: The + pole shall be connected to one of the left terminals in the PSU connector with the BROWN part of the DC cable. The — pole shall be connected to one of the right terminals in the PSU connector with the BLUE part of the DC cable. 8.When the connection is completed, switch the repeater on. 9.Make sure the yellow LED is lit on the PSU. The DC Power Supply Unit must be galvanically separated from the mains supply with an equipment fulfilling the 1EC65 safety requirements. 3 - 14Rev. 48 W98-03User’s Manual VD2O1 171EN Figure 3-9.

Band selective configuration The left-hand part of the configuration window contains downlink information (BSA board #1 and PA board #1 located to the left in the cabinet or cover). The right-hand part of the configuration window contains uplink information (BSA board #2 and PA board #2 located to the right in the cabinet or cover). The downmost line indicates current band width and the band width status (fixed or adjustable). Fixed band width operation For repeaters equipped with fixed band width BSA boards, the following three fields are changeable: Downlink:Gain Uplink:Set low band edge Gain The values in the remaining fields are automatically calculated from the band width and the uplink/downlink frequency difference. Adjustable band width operation For repeaters equipped with adjustable band width BSA boards, the uplink ‘Set high band edge’ field is also available and changeable.

The PA boards and the AGC (Automatic Gain Control) are turned off when the band selective repeater is switched off. ‘Downlink’ section Low band edge Displays the downlink low band edge related to the uplink low band edge. The difference is depending on the system duplex spacing. High band edge The downlink high band edge related to the band width. Gain The maximum downlink gain, i.e. the total gain from antenna port to antenna port. Setting range: 45dB to 90dB ‘UpIink’ section Set low band edge The lower band edge for the uplink signal. The band edge frequency can be increased or decreased by clicking the arrow buttons. The frequency is changed in 12.5KHz steps. Values can be typed into the field as well. Setting range for this field is depending on the system and BSA boards. Set high band edge For fixed BSA boards, this field displays the uplink high band edge related to the band width. This band edge cannot be changed solely. For adjustable BSA boards, this field is changeable and affects thus the uplink high band edge and thereby the band width. Gain The maximum uplink gain, i.e. the total gain from antenna port to antenna port.

The EUT with host external computer was configured for maximum signal gain and bandwidth. The EUT was operated in a manner representative of the typical usage of the equipment. During all testing, system components were manipulated within the confines of typical usage to maximize each emission. 5.0TEST TYPE(S) 5.1Radiated Emissions: 47CFR2.993, 22.901(d)(2), 22.917(e) 5.2Occupied Bandwidth: 47CFR2.989, Input vs. Output 5.3RF Power Output: 47CFR 2.985, 22.913(a) 5.4Spurious Emission at Antenna Terminals:(uplink & downlink) 47CFR 2.991, 22.917(e) 5.5Intermodulation Spurious Emissions-3 Tone Simultaneous RF Injection (uplink & downlink): 47CFR2.991, 22.917(e). 5.6AC Line Conducted Emissions: 47CFR 15.107 FCC ID: L6GAR4500 EMI1164A- 4 -February 9, 1999 6.0TEST RESULTS 6.1TEST TYPE: Radiated Emissions 6.1.1 TECHNICAL SPECIFICATION:2.993; 22.109(d); 22.917(e) 6.1.2 TEST DATE(S):1 Feb 1999 6.1.3 MEASUREMENT PROCEDURES: As required by §2.993, field strength of spurious radiation measurements were made in accordance with the general procedures of ANSI C63.4-1992 "Methods of Measurement of Radio- Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9kHz to 40 GHz". Preliminary radiated emission measurements were performed inside a shielded chamber with all digital signal generators on and terminated. The frequency list from the preliminary measurements was used as a guide for making final measurements on a 10 meter open area test site. The unit was scanned over the frequency range of 30MHz to 9 GHz. The Radiated Spurious Emissions Limit is obtained by the following: Based on an output power (as measured at the output of the Amplifier) of 3 watts: P o = 3 W As per 2.993 (a), it is assumed this power is to be fed to a half-wave tuned dipole. Using a conversion formula for distance, the field strength at one meter can be derived: As per 22.917(e), the spurious emissions must be attenuated by 43 + log(P) which is: Therefore, the limit for spurious emissions is: At 3 meters measurement distance, the limit is; According to 22.917(e), all signals must be attenuated by 47.77 dB. Therefore, the limit for spurious emissions for a test distance of 3 meters is: Install Equation Editor and double- click here to view equation.
