CI Wireless Inc. General InformationMirrorCell Select CDR812 ManualRev. X1 1-11 GENERAL INFORMATIONThe CDR812 is a channel-selective CDMA repeater, designed to be fully compliant withTIA/EIA/IS-95, titled “Mobile Station-Base Station Compatibility Standard for DualWideband Spread Spectrum Cellular System” specifications. Separate modules are usedfor each channel in both the transmit and receive directions. Each module selects achannel in a given direction (transmit or receive) and amplifies it. Standard forward pathoutput power is 5W (37 dBm) per channel for two-channel system. Reverse path outputpower is 0.25W (24dBm) per channel for two-channel system.The repeater is outfitted with two channels for each radio frequency path. The frequencyand amplification of each channel can be individually controlled. The monitoring andcontrol of the system occurs with a direct connection to a laptop computer or via awireline option for remote access by modem.Figure 1. Block Diagram of the CDR812 repeater.The CDR812 consists of several modules: the duplexer, LNA (Low Noise Amplifier),Channel Module (also known as Channelizer), and Power Amplifier. The reverse andforward directions consist of similar modules.The primary frequency stabilization for the CDR812 CDMA repeater is provided by the 10MHz temperature stabilized crystal oscillator, which provides a temperature compensatedbasic reference frequency for the PLL that provides the local oscillator frequency. Thebasic settable frequency accuracy is 5 ppm. All internally generated frequencies areDonorAntennaDuplexer DuplexerSyn. Osc. Syn.MixerMixer SAW FilterCh. 1Syn. Osc.

CI Wireless Inc. Attenuation Control of the AmplifierMirrorCell Select CDR812 ManualRev. X1 5-15 ATTENUATION CONTROL OF THE AMPLIFIERThe MirrorCell Select CDMA repeater offers 30dB of user-settable attenuation tocustomize the desired output of the repeater. The amplifier can be attenuated in 2dBsteps, from 0dB to 30dB. Ortel recommends that you start with 30dB of attenuation andslowly decrease attenuation, thereby increasing output power, in order to ensure therepeater transmits only the desired amount, and not more. This will help to reduceinterference caused by too much output power.The following table is a guideline for setting the attenuation.Attenuation Nominal Gain Setting(dB) (dB)40 dBm Output0 952 934 916 898 8710 8512 8314 8116 7918 7720 7522 7324 7126 6928 6730 65

CI Wireless Inc. Description of the Control ModuleMirrorCell Select CDR812 ManualRev. X1 6-16 DESCRIPTION OF THE CONTROL MODULE6.1 GeneralThe repeater is equipped with a status & control module, which allows the monitoring andcontrol of various parameters such as channel number, attenuation, temperature, statusof door, etc., either with a local terminal or via OMC. The communication interfacebetween the local terminal and the control module is set up as a self-explanatory menufor simple manual control and monitoring. This way, the parameters can be easily readoff of and set up from the display.6.2 SettingsThe physical interface to the control module consists of a VT-100 series terminalconnected to the repeater. Specifically, you will need a laptop computer with a terminalemulation program, such as ProComm or Hyperterminal, connected to the repeater via aDB9 straight-through serial cable with a male connector for the repeater side and afemale connector to hook up to the computer’s RS232 serial port.The communication format must be set in the terminal emulation program:• 9600 baud• 8 bit• 1 stop bit• No parity• No flow control (flow control = none)6.3 Login via Local Maintenance Terminal (LMT)When the PC is connected to the repeater, the login sequence is activated by user-inputkeystrokes. (See Section 7.6 in the Installation chapter for greater detail.) The loginsequence begins by asking for Username and Password. Different user accounts havedifferent authorities. The default login parameters are:User Name Password AuthorityUSERNAM1 PASSWRD1 read/writeUSERNAM2 PASSWRD2 read/writeUSERNAM3 PASSWRD3 read onlyUSERNAM4 PASSWRD4 read onlyNote: The Usernames and Passwords should be changed during installation. SeeSection 7.6, step 6.For example, to change the second Username and Password:SET UID2 ORTEL <enter>SET PWD2 Alhambra <enter>For more information, see section 6.10.3.
Description of the Control Module CI Wireless Inc.MirrorCell Select CDR812 Manual6-2 Rev. X1The control module logs the number of failed login attempts. If this number exceeds theuser-defined maximum (ILA, default = 8), then future login attempts will be blocked. Thefalse login count is decreased by one each hour. This means you must wait one hourafter reaching the maximum number of failed login attempts before a single login can beinitiated.6.4 CommandsThe control module does not differentiate between upper- and lower case characters.Command attributes and parameters can be viewed in the tables in section 6.10.Available commands:• ADDRESS Gives information about current address configuration.• CLEAR Clears the display.• CLOCK Displays a real-time clock.• HELP Displays a quick overview of commands.• LOG Shows the alarm log.• LOGOUT Ends the work session.• STATUS Displays the RF parameters (channel number, attenuation,etc.), as well as peripheral parameters (current draw, statusof door).• SYSTEM Shows system data (number of messages).• SET, GET These commands allow the monitoring and control of therepeater’s parameters.All user editable parameters and current status of the repeater can be accessed usingthe GET and SET commands. Refer to section 6.10 for the format of the differentattributes.Note: The command field must be completely used; otherwise an error results.Two parameters are writable only, not readable; these are Username and Password. Seetable 6.10.6.The syntax for the GET command is:GET [Attribute] <enter>For example, to get the status of the forward path amplifier chains:GET AMD <enter>The syntax for the SET command is:SET [Attribute] [Format] <enter>Where all entries must be separated by a blank space. For example, to set the channelnumber for the repeater’s channel 1:
CI Wireless Inc. Description of the Control ModuleMirrorCell Select CDR812 ManualRev. X1 6-3SET CHA X YYY <enter>where X = channel within the repeater and YYY = the CDMA channel number. Thechannel can be set only to channels within your system’s band of operation.6.5 Quick CommandsThree quick commands are available with the function keys:• F1: Help Menu• F2: Shows a list of the last ten entered commands• F3: Shows the Status screen.6.6 Command LogThe control module stores the last ten commands that have been entered. The F2 buttonbrings up these commands. Use the up and down arrow keys to read off these storedcommands. The right and left arrow keys can then be used, along with backspace andclear, to edit the commands as needed.6.7 Configuring the External AlarmsThe external alarms can be configured active-low or active-high, so the alarm is given ineither the absence or presence of applied power. Input voltage can range from 12 VDC to24 VDC. For configuration, use the following command:SET EXT BC <enter>where B refers to pin 1 and C refers to pin 2.B or C = 0 means the absence of voltage is normal,B or C = 1 means the presence of voltage is normal.The alarms are laid out so that pin 1 is read from EX1 and pin 2 is read from EX2.6.8 LED IndicatorsThe LEDs on the control module are tri-colored, where the illuminated colors mean:• GREEN: Repeater is functioning properly• AMBER: User is logged in to the control module• RED: Repeater is not functioning properlyNote: Depending on the alarm configuration, the door alarm may go off a number ofseconds after the door has been opened; in this case, the LED will change from Amber toRed.

CI Wireless Inc. Description of the Control ModuleMirrorCell Select CDR812 ManualRev. X1 6-96.11 Alarms and Alarm Configuration6.11.1 OverviewThe MirrorCell Select CDMA repeater can send alarms to an Operations andMaintenance Center or to the MirrorCell Element Manager (MEM), both referred to as theOMC in this document, via a DataCall (modem connection). For each alarm sent, an endof alarm will also be sent when the end of alarm condition is detected. This does notinclude VLI, LGO, CLR, and ILI alarms. By default, the repeater requires anacknowledgement of each alarm sent. When using SMS, all letters must be capitalized.Each alarm source can be individually configured. The software has the capability toenable or disable the requirement to acknowledge particular alarms (not including VLI,LGO, CLR, and ILI alarms), and the capability to configure different threshold forparticular alarms. In addition, if a particular alarm condition arises which causes the alarmto toggle between OK and ERROR, the software has the capability to adjust the MinimumAlarm Repetition (MAR) time and the Maximum Number of Repetitions (MNR). This willkeep the repeater from blocking the communication interface with a series of Alarm/Endof Alarm notifications. (See section 6.11.7.2, “Minimum Alarm Repetition Time” for moreinformation on this feature.)

Description of the Control Module CI Wireless Inc.MirrorCell Select CDR812 Manual6-16 Rev. X16.11.7.2 Minimum Alarm Repetition TimeThis command has been introduced for the case where an alarm is toggling between OKand ERROR. In this state, the repeater should not continuously call the OMC with thenew alarm detected for the same fault condition and potentially block the communicationbetween the repeater and the OMC. Typically the MAR should be set to a minimum oftwo or three times the amount it takes for the repeater to dial up and report the alarm.MAR is expressed in minutes, and the default value is 3.Note that the first error will always be detected within the normal threshold time. Only therepeated alarms will be blocked. If numerous alarms are received at the OMC, theoperator must be able to send a message to disable the particular alarm at the repeateruntil service of the repeater can be performed.For example, to set Minimum Alarm Repetition:SET MAR 5 <enter>This will set the alarm repetition time to 5 minutes.Figure 3.

X1 7-17 INSTALLATION OF THE CDR8127.1 Shipment Contents• Repeater• Operator’s manual• Wall mount brackets• Keys for repeater’s locks• “Quick Tips”7.2 Site SelectionSite selection for the repeater is one of the most critical decisions affecting the overallperformance of the repeater system. A repeater must be located where it can receive asufficient signal from the donor site in order to maximize the repeater’s performance. For40dBm output, an input signal strength at the donor input connector (after the donorantenna and coax cable) of greater than or equal to –55dBm is required for a 40dBmoutput: -55dBm + 95dB gain = 40dBm.Examples of repeater and accompanying antenna locations include, but are not limitedto:• the roof of a building adjacent to the affected area with the antennasmounted to the penthouse or building sides• the top of a hill that is obstructing the donor site’s coverage, with theantennas pipe-mounted at ground level• a water tower with antennas mounted at the top• an existing utility pole, with equipment and antennas mounted below anyexisting power lines• a newly installed pole or tower.For more detailed information on site selection, as well as antenna selection andplacement, please see CI Wireless’ Application Note: “Integrating MirrorCell SelectRepeaters into a CDMA Network.”7.3 Antenna SelectionProper selection of the repeater’s donor and server antennas is crucial in designing therepeater system. Good antenna characteristics help to provide proper isolation betweenthe server and donor antennas, which helps to prevent feedback.The donor antenna selected for use with a CDR812 is critical in the design of a properlyfunctioning repeater system. Since in CDMA systems all of the base stations transmit thesame frequency, the donor antenna selected must be capable of receiving only thedesired base station. Microwave dish antennas with vertical and horizontal beamwidths of
Installation of the CDR812 CI Wireless Inc.MirrorCell Select CDR812 Manual7-2 Rev. X1less than 15° are ideal candidates for the donor antenna. Microwave dish antennas alsoprovide the recommended front-to-back ratio of greater than or equal to 25dB to helpachieve the required antenna isolation.The server antenna should provide the desired coverage and also provide therecommended front-to-back ratio of 25dB. Many different types of antennas will work as aserver, such as panel antennas, Yagi antennas, and, for indoor applications, Omni-directional antennas.The isolation between antennas must be at least 10dB greater than the gain setting of therepeater or the repeater could go into oscillation. Specific ways to achieve properisolation include:• using high gain, directional antennas with good front-to-back ratios (>25dB).Also evaluate and select antenna with the desired antenna radiation pattern(vertical and/or horizontal) that provides adequate insertion loss at angle(s)of separation.• pointing the donor and server antennas opposite each other; ie, at 180° fromeach other• physical separation of the repeater’s donor and server antennas, eithervertically or horizontally• external shielding, such as wire mesh or a grounded metal plane.Antenna isolation limits the amount of gain to which the repeater should be set.Therefore, if isolation is less than 105dB, the repeater cannot be set to the maximum gainof 95dB.7.4 Antenna Mounting7.4.1 Donor AntennaUse the following steps to mount the donor antenna.1. Mount donor antenna at initially desired location.2. Measure the received signal strength from the donor site. The amount of power therepeater can produce is dependent on this signal level. Note whether the donor isloaded or unloaded, as this will affect the amount of power needed.3. If a greater signal strength is needed, try raising the donor antenna’s height, or use ahigher gain antenna, if possible.4. Measure the pilot tone strength received after the donor antenna and verify that theproper base station sector is being received. The pilot tone of the desired basestation should be at least 15dB higher than any of the other received pilot tones. Ifthis is not the case, the donor antenna should be adjusted until the desired pilot toneis 15dB greater than any other received pilot tones. (Note that this requires a CDMAsignal measurement device.)
CI Wireless Inc. Installation of the CDR812MirrorCell Select CDR812 ManualRev. X1 7-37.4.2 Server Antenna Mounting and Isolation MeasurementsIsolation measurements should be taken to ensure proper operation of the repeater.Measurement of isolation can be accomplished easily by following the procedures, asillustrated in Figure 15.1. Mount server and donor antennas at initially chosen location to obtaindesired coverage.2. Inject a known signal within the bandwidth of operation into the donorantenna. An unused channel within the band should be used. The signalshould be at least 1W in order to allow for an accurate measurement ofisolation. The repeater and a low-power signal generator can be used inseries to generate a signal of sufficient strength. The repeater will add 65dB– 95dB of gain, depending upon how much attenuation is added to therepeater.3. Connect a signal measurement device, such as a spectrum analyzer, to theserver antenna. Measure the received signal level. The difference betweenthe signal input to the donor antenna and the received signal measuredafter the server antenna is the antenna isolation. (Note that the gain of theantenna is not used in the calculation.)Figure 4. Isolation Measurement Setup.SPECTRUMANALYZERRF InSIGNALGENERATORRF Out
Installation of the CDR812 CI Wireless Inc.MirrorCell Select CDR812 Manual7-4 Rev. X1Antenna isolation can be measured once the donor and server antennas have beenmounted at their initially desired location. Isolation measurement is important in properlysetting up a repeater.4. The repeater gain can be set to at least 10dB below the figured measuredabove. (The antenna isolation must be at least 10dB greater than therepeater gain.) For example, if the antenna isolation measured is 90dB, therepeater gain should be set for no more than 80dB.5. If isolation is not great enough (ie, if more gain is required), you can try eitherof the following:a. Separate the antennas by a greater distance.b. Mount some type of external shielding between the antennas, such as amesh screen, an ice shield, or grounded metal plate.7.5 Repeater Mounting and InstallationThe following recommendations should be adhered to for enhanced repeaterperformance.1. The repeater comes standard with wall mount brackets as shown in Figure16. The brackets attach to the repeater with eight M8x1.25 thread boltscrews, included in the shipment.2. The repeater should be mounted so the heatsink avoids direct sunlight. Thiswill help improve the lifetime of the repeater.3. Mount the repeater upright so that the connectors are on the underside. Thiswill help prevent a buildup of moisture inside the repeater.4. The repeater is equipped with 7/16” DIN (or N-type as an option) antennaconnectors. Connectors are located at the bottom of the unit. A protectivecover is included with the repeater to prevent unauthorized access to theconnectors. The cover can be installed or removed only from the inside of theunit.5. Ensure that adequate room has been allocated for the bending radius of thecables. Refer to the cable manufacturer’s specifications for the allowablecable-bend radius.6. Ensure that adequate room is allowed for the opening and closing of therepeater door. See Figure 16 for dimensions of the repeater.

Then, attenuation levels can be reduced until thedesired output power is achieved. This reverse attenuation should then be set equalto the forward attenuation to maintain path balance.10. Set the peak levels at which the repeater should transmit in the uplink (reverse) anddownlink (forward) directions. Forward peak levels for the standard repeater are34dBm, 37dBm, and 40dBm. Reverse peak levels for the standard repeaters are21dBm, 24dBm, and 27dBm. Note that due to low output power from the mobile,reverse path power rarely exceeds 20dBm.To set the peak level in the reverse path:SET LVU X YY N MM<enter>X = Repeater’s channel 1YY = Reverse maximum transmit level for channel 1N = Repeater’s channel 2MM = Reverse maximum transmit level for channel 2.SET LVU 1 27 2 27<enter>To set the peak level in the forward path:SET LVD X YY N MM <enter>X = Repeater’s channel 1

The repeater now should be configured for operation.11. The repeater should be turned off before connecting it to the antennas. Onceconnected, the repeater can be turned on. The output power of the repeater shouldbe monitored on the test port. The test ports are 30dB couplers; thus if an outputpower of 40dBm (2W) is desired, the power measured at the test port should be10dBm. The attenuation of the repeater should be decreased until the desired outputpower is achieved.7.7 OptimizationNow that the repeater is providing the desired output power, the system needs to beoptimized. The search window and neighbor lists of the donor base station should bereviewed. Verify the pilot search window parameters are properly set to compensate forfilter group delays in the repeater. The repeater uses highly selective Surface AcousticWave (SAW) filters, which have a group delay of 11 microseconds. Since the propagationdelay of free space is 5.4 microseconds per mile, the delay is “equivalent” to two miles offree space propagation.The search window of the donor base station may need to be increased depending onthe distance from the repeater to the donor base station. For example, if the repeater is 3miles from the donor base station, and the desired coverage area of the repeater is 2miles (for a total of 5 miles):(5 miles) * (5.4 µsec/mile) + 11 µsec (delay in the repeater) = 38 µsecThe donor BTS pilot search window would need to be at least 38 microseconds for callactivation to take place.The neighbor lists of the donor base station and the base stations surrounding the areaserved by the repeater need to be adjusted. For example, in Figure 19 a repeaterextends the coverage of BTS1 to a new area. BTS1 is now neighbors with BTS4 andBTS5, whereas without the repeater, BTS1 is neighbors with just BTS2 and BTS3. ThusBTS4 and BTS5 must be added to BTS1’s neighbor list, and BTS1 must be added toBTS4’s and BTS5’s neighbor lists. A drive test of the coverage area should be performedto verify the final setup.
