User’s manual for Repeater MRx01B Manual update MR301.doc Id.-No. 151775Page 1315-November-00 1 INTRODUCTION 1.1 Intended purpose Cellular telephone systems transmit signals in two directions between base stations and mobile telephones within the signal coverage area. If weak signal transmissions occur within the coverage area because of indoor applications, topological conditions or distance from the transmitter, a repeater is used to extend transmission range. In the downlink path the repeater picks up the signal from a donor antenna of an existing cell, amplifies and re-transmits it into the desired dark spot. In the uplink direction the repeater receives signals from mobile stations present in its coverage area and re-transmits them to the corresponding base station. The over the air radiated use of this repeater is intended to be used with either Roof Top or Pole Mounted Antennas. To provide coverage in a indoor application one must mount the antennas on or outside the building structure that is occupied. This must be done in a matter that conforms to the FCC RF exposure ( See health and Saftey section of this manual). 1.2 About the MRx01B This repeater bi-directionally amplifies signals between multiple mobiles and a single base station in the frequency band. It is employed where poor topological conditions cause weak field strengths. It can provide highly selective amplification of band segments or channels in the frequency band. The MRx01B can be set-up locally or remotely. A PCMCIA slot for modem operation is an available option. The repeater has a large number of functions that can be monitored and changed by the operators via a terminal emulation program or the MIKOM OMC software platform. An easy to understand and simple to learn communication language is available to help the operator query status reports from the repeater or to change settings.

For any clarification, please refer to FCC rules, 47 CFR ch. I, part 1.1307 The MRx01B repeater’s modular design provides the flexibility in addressing present and future system needs. Each repeater is custom configured. The main unit includes equipment common to all systems ( cabinet, control module, power supply, mother board ). To this main unit hardware modules are added as needed. In addition to different duplexers, a wide range of conversion modules can be selected depending on the used network system. MRx01B modules operating in PCS, PAGING900, AMPS800, or LMR\IDEN800 bands are available.

Response to TCB findings Hi David, We have identified the following issues after our review of the application: 1. Please explain why a three signal inter modulation test was not provided with the test reports. Response - Please find attached test reports with the 3-signal intermodulation. 2. Please identify the DC currents and voltages in the final amplifier stage. The exhibit you supplied does supply this data. Response -The DC voltages are +8 Vdc and +12 Vdc in the final rf amplifier module. The maximum DC current is 1.5 Amps. 3. The technical description seems to indicate that the power level can be varied by attenuator switches. We see data for only one power level. Much of the documentation only appears to address the maximum power. If the device is operated at multiple power levels, then we need antenna conducted data for both the highest and lowest power levels. Response - Attenuator switches can be varied on the input to reduce the input level so that it does not exceed the maximum input level of the rf input of the amplifier. The rf power output is not variable but is controlled by the ALC in the rf output. This ALC is set so that the amplifier will limit rather than transmit an rf output power above the manufacturer's specification limits. 4. Please supply the agency agreement between Nemko/KTL and the applicant. Response - Supplied Best regards Barry C.

The explanation how it works is made with reference to the following figures and exemplary values for frequencies, bandwidths and levels. There are two filters in one link (UL or DL) in series in the band module which can be set to a defined centre frequency. In the example we have two filters with a bandwidth of 25 MHz each and for demonstration purposes the frequency range is 870 to 940 MHz. In figure 1 we see that filter 1 and filter 2 are both set to a centre frequency (CF) of 900 MHz. The resulting overall response of the module is thus a 25 MHz band with a centre frequency of 900 MHz (⇒ frequency range from 887.5 MHz to 912.5 MHz). The attenuation in the stop band of one filter was assumed to be 40 dB. Thus, the overall attenuation of the module is 80 dB. figure 1figure 2 Description of band modules with variable bandwidth M0050A0C.docId.-No. 148222Page 4 of 1128-Oct-99 In figure 2 we have the same filters but this time with different centre frequencies. The centre frequency of filter 1 is this time 912.5 MHz and the centre frequency of filter 2 is again 900 MHz. Consequently, we get another overall response of the module as can be seen in figure 2. Filter 1 limits the frequency range towards lower frequencies and filter 2 towards higher frequencies. The resulting response is thus an attenuation of 80 dB up to 881.25 MHz, 40 dB up to 893.25 MHz, 3 dB bandwidth is 12.5 MHz from 900 MHz to 912 MHz, 40 dB attenuation from 918.75 MHz and 80 dB from 931.25 MHz. (Values exemplary!) It is shown in the following how the centre frequency and the bandwidth of the module can be set to desired values. Description of band modules with variable bandwidth M0050A0C.docId.-No. 148222Page 5 of 1128-Oct-99 2 Integrating a conversion module and programming communication bus address FF Note: Do not use conversion modules with variable bandwidth together with conversion moduls with fixed bandwith on the same mother board. 2.1 What you have to know of your system before the setting Prerequisite for the adjustment is to know the bandwidth of the filters used in the module. (See the label on the conversion module.) With this bandwidth and the desired values the start frequency and stop frequency (and thus the bandwidth and centre frequency) of the band can be set. The following formula shows how to calculate the values that have to be entered. 2 1 filter Start BW fCF+= 2 2 filter Stop BW fCF−=; where CF1 is the centre frequency of the first filter (to be entered) CF2 is the centre frequency of the second filter (to be entered) f Stop is the stop frequency of the desired band (upper frequency): f Stop = CF des + BW des /2 f Start is the start frequency of the desired band (lower frequency): f Start = CF des - BW des /2 (CF des and BW des are the desired center frequency and bandwidth of the desired band) BW filter is the bandwidth of the two filters of the module BW filter BW filter /2 f Start CF1 f Stop CF2 BW des CF des figure 3 Description of band modules with variable bandwidth M0050A0C.docId.-No. 148222Page 6 of 1128-Oct-99 2.2 Setting the bus address of the module Another thing to know is the allocation of the filters to the respective links. Each filter is allocated to a link and a filter number by means of hex-coded rotary switches. Each rotary switch can be set to positions from 0 to F (16 positions) by means of a small screw driver. This adjustment is important if you want to replace a module or upgrade your system. If the module was inserted in factory you don’t have to care about that. The following figure shows where the hex-coded rotary switches are located and the table shows the allocation.
