AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL IV DOC PN 0034B-UM REV. 2.1 © Axell Wireless Ltd Part 90 Signal Boosters THIS IS A 90.219 CLASS A DEVICE WARNING: This is NOT a CONSUMER device. This device is designed for installation by FCC LICENCEES and QUALIFIED INSTALLERS. You MUST have an FCC LICENCE or express consent of an FCC Licensee to operate this device. You MUST register Class B signal boosters (as defined in 47 CFR 90.219) online at www.fcc.gov/signal-boosters/registration. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation. The installation procedure must result in the signal booster complying with FCC requirements 90.219(d). In order to meet FCC requirements 90.219 (d), it may be necessary for the installer to reduce the UL and/or DL output power for certain installations. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation.

AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd DOC PN 0034B-UM REV. 2.1 V Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this transmitter must be mounted on permanent structures. The FCC regulation mandate that the ERP of type A signal boosters should not exceed 5W, this is equivalent to 8.2W EIRP. Therefore the max antenna gain allowed for this type of signal booster should be limited to the values given by equation (1) for the service antenna and equation (2) for the donor antenna Equation (1) - Max SERVICE antenna gain Max SERVICE antenna gain (dBi) = 39.1 – (33dBm - # of antennas in dB – cable losses in dB). For example: No. of Antennas Cable Losses Max Allowed Antenna Gain 4 3 39.1 - (33-6-3) = 15.1dBi 1 3 39.1- (33-3) = 9.1dBi 10 3 39.1- (33-10-3) = 19.1dBi Equation (2) - Max DONOR antenna gain Max DONOR antenna gain (dBi) = 39.1 – (27dB - cable losses in dB). For example: No. of Antennas Cable Losses Max Allowed Antenna Gain 1 2 39.1 - (27-2) = 14.1dBi Compliance with FCC deployment rule regarding the radiation of noise Good engineering practice must be used in regard to the signal booster’s noise radiation. Thus, the gain of the signal booster should be set so that the ERP of the output noise from the signal booster should not exceed the level of -43 dBm in 10 kHz measurement bandwidth. In the event that the noise level measured exceeds the aforementioned value, the signal booster gain should be decreased accordingly. In general, the ERP of noise on a spectrum more than 1 MHz outside of the pass band should not exceed -70 dBm in a 10 kHz measurement bandwidth. The 3302 signal booster has a noise level of -55 dBm in 10 kHz measurement at 1 MHz spectrum outside the passband of the signal booster and an in-band noise level at around -50 dBm in a 10 kHz bandwidth. Therefore, the noise at the antenna input port should be calculated based on equation (3). Equation (3) - Input Noise to service antenna Input Noise to service antenna: -55 dBm + Service Antenna gain – Antenna splitter losses in dBi – cable loss in dB
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL VI DOC PN 0034B-UM REV. 2.1 © Axell Wireless Ltd Example: Signal booster connected to 10 service antennas with a 100m long ½ inch cable. Losses of such a cable with the connectors = ~ 11dB Gain = ~ 2 dBi Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (3) Input antenna noise (to the antenna) = -55+2-11 -11=-75 dBm The inband input noise to the antenna should be -50+2 -11-11= -70dBm NOTE: In this example there is no need to add an external band pass filter to attenuate the out of band noise. Conclusion: Good engineering practice requires that in general when the out of band noise measured at the service antenna input is more than -70 dBm per 10 kHz measurement bandwidth, an external band pass filter should be added to attenuate the out of band noise level. All Axell Wireless repeaters include high selectivity duplexers and filters to attenuate the out of band noise. Should additional filtering be required, we have a comprehensive range of interference filters which can be supplied upon request. Compliance with IC Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. This equipment complies with IC RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance of 58cm between the antenna and your body, La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son fonctionnement avec porteuse unique. Pour des appareils avec porteuses multiples, on doit réduire la valeur nominale de 3.5dB, surtout si le signal de sortie est retransmis et qu'il peut causer du brouillage aux utilisateurs de bandes adjacentes. Une telle réduction doit porter sur la puissance d'entrée ou sur le gain, et ne doit pas se faire au moyen d'un atténuateur raccordé à la sortie du dispositif. Cet appareil est conforme aux limitations de la norme IC RSS-102 concernant l’exposition aux radiations dans un environnement non contrôlé. Cet appareil doit être installé et utilisé avec une distance minimale de 58cm entre l’antenne et le corps de l’utilisateur.
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd DOC PN 0034B-UM REV. 2.1 VII General Safety Warnings Concerning Use of This System Always observe standard safety precautions during installation, operation and maintenance of this product. Only a qualified and authorized personnel should carry out adjustment, maintenance or repairs to the components of this equipment. NOTE: Please refer to Axell Wireless for additional information and for requests for notifications to authorities. Caution labels! Throughout this manual, there are "Caution" warnings. "Caution" calls attention to a procedure or practice, which, if ignored, may result in injury or damage to the system, system component or even the user. Do not perform any procedure preceded by a "Caution" until the described conditions are fully understood and met. Danger: Electrical Shock This equipment can either be installed indoors or outdoors. When installed outdoors - wet conditions increase the potential for receiving an electric shock when installing or using electrically powered equipment. To prevent electrical shock when installing or modifying the system power wiring, disconnect the wiring at the power source before working with un insulated wires or terminals. Caution: RF Exposure RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to AWL’s equipment, must be considered a safety hazard. This condition might only occur in the event of cable disconnection, or because a ‘spare’ output has been left un-terminated. Either of these conditions would impair the system’s efficiency. No investigation should be carried out until all RF power sources have been removed. This would always be a wise precaution, despite the severe mismatch between the impedance of an N type connector at 50Ω, and that of free space at 377Ω, which would severely compromise the efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power carrying components were to be carelessly touched! Where the equipment is used near power lines or in association with temporary masts not having lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised. For FCC compliance, the Maximum Channel output must be <5 watts. Warning: Antenna Installation Antenna positions should be chosen to comply with requirements (both local & statutory) regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of producing RF field strengths, which may exceed guideline safe values especially if used with antennas having appreciable gain. In this regard the use of directional antennas with backscreens and a strict site rule that personnel must remain behind the screen while the RF power is on, is strongly recommended. Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this transmitter must be mounted on outdoor or indoor permanent structures. The maximum antenna gain for indoor operation is 2.2 dBi. In indoor applications the antenna must be installed at a minimum separation distance of 58 cm from all nearby persons.

AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 8 Doc PN 0034B-UM Rev. 2.1 © Axell Wireless Ltd 2.3 RF Cabling Requirements  For all coaxial connections to/from the Repeater - high performance, flexible, low loss 50Ω coaxial communications cable.  All cables shall be weather-resistant type.  Cable length - determined by the Repeater installation plan. When calculating the cable length, take into account excess cable slack so as not to limit the insertion paths.  Make sure that cable and connector are compatible. Using cables and connectors from the same manufacturer is helpful.  All connectors must be clean and dry  Waterproof all outdoor connections using silicone, vulcanizable tape or other suitable substance as moisture and dust can impair RF characteristics.  Make sure enough room has been allocated for the bending radius of the cable. RF cables must not be kinked, cut or damaged in any way  Connect the RF cable to the antenna tightly but without damaging threads  Fasten cables tight to cable ladder or aluminum sheet  For short length of feeder cables use ½ “, for longer feeder cables use 7/8”. Chose thicker coax cables for lower attenuation. Minimize the length of the coax cables to reduce the attenuation  Use jumper cable for easy installation. The RF Coaxial cable can be substituted at each end with a jumper cable.
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd Doc PN 0034B-UM Rev. 2.1 9 3 Pre-Installation Requirements 3.1 Safety Guidelines Before installing the Repeater, review the following safety information:  Follow all local safety regulations when installing the Repeater.  Only qualified personnel are authorized to install and maintain the Repeater.  Ground the Repeater with the grounding bolt located on the underside of the Repeater.  Do not use the grounding bolt to connect external devices.  Follow Electro-Static Discharge (ESD) precautions. 3.2 Required BTS Information Required BTS Information  BTS channels  BTS output power per channel  BTS antenna gain  BTS antenna height  Distance from Repeater site to BTS 3.3 Selecting a Location Select a location that will take into account the following criteria:  Relative location of Base Station  Cooling and airflow  Wall compatibility  Access to the repeater for installation or maintenance 3.3.1 Relative Location of Base Station The repeater site shall be located where the BTS signal strength is great enough to be recognized by the system. For example, a D-CSR 3302 (85dBm max gain) and signal strength of -70dBm at the pickup antenna, a gain in the pickup antenna of 10dBi, a repeater gain of 85dBm and a server antenna gain of 2dBi the resulting ERP would be 27dBm. Losses in cables and other elements would change these figures slightly.  Repeater location near enough to BTS for received signal to be of adequate strength  Ideally the repeater’s donor antenna should have line of sight (LOS) contact with the BTS antenna. If the signal strength is high enough, LOS may in some cases not be necessary.  Distance from antenna site - It is recommended that the installation location be as close as possible to the antenna site in order to maintain the cable loss to a minimum. 3.3.2 Cooling and Airflow  Install the Repeater in a shielded, ventilated, and easy-to-reach area.  The Repeater is convection cooled so airflow and alternation should be possible.  Verify that ambient temperature of the environment does not exceed 50C (122F) Mount the repeater so that heat can be dispersed from it. The repeater wall mounting kit ensures an optimum airflow between the wall and the repeater itself. Do not block this air
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 10 Doc PN 0034B-UM Rev. 2.1 © Axell Wireless Ltd channel as it will cause the MTBF of the repeater to drop dramatically, or even in the worst case cause the repeater to fail completely. If possible use a wall in the shadow to minimize the overall sun loading. If sufficient shielding cannot be obtained, an additional sun shield should be mounted. 3-1. Example of a sun shield outdoors Operating Temperature The D-CSR repeaters are designed primarily for multi carrier purposes. If the repeater is run at full output power over a long period of time the convection cooling might not be enough. The repeater has a power management function implemented that will step down the power and if needed fully shut down the amplifier chains until temperature has reached normal values. In situations where a repeater will be run in such a manner extra cooling can be provided for instance by putting the repeater in a temperature controlled environment or via external fans. 3.3.3 Wall Compatibility  Check the suitability of the wall on which the Repeater is to be mounted.  The Repeater wall mount brackets assembly should be fixed to a solid wall (these include brickwork, blockwork, and concrete.);  (Due to the weight of the Repeater, it is NOT recommended to fix to a hollow wall). 3.3.4 Access to the Repeater  Plan connection cable clearances - the Optical, RF and power connections located on the underside of the Repeater will need at least 300mm vertical clearance below the Repeater to enable the connections to be made. The minimum bend radius for Optical and RF cables must not be less than the recommendations made by the cable manufacturer. Plan the cable runs and ensure adequate space is available.  Allow for door opening - ensure that there is sufficient space at the front of the Repeater to allow the door to be fully opened and for maintenance engineers to get access to the unit with test equipment such as a spectrum analyser.  Allow space around the repeater - verify that there is a minimum of a 50 cm (20”) radius of space around the Repeater, enabling easy access to the repeater for maintenance and on-site inspection. Allow an additional 50 cm of space in front of the Repeater when the door is fully open.  Monitoring repeater - install the Repeater close to the service area to monitor the output power.

If insufficient Electromagnetic Protection is provided, or if EMV measures are not taken, warranties issued by Axell Wireless are not valid. The lightning hazard to electric and electronic equipment consists in the interferences of direct lightning current infections and high surge voltages induced by the electromagnetic field of nearby lightning channels or down conductors. Amplitudes from cloud-to-earth lightning amounts to several 10kA and may last longer than 2(ms). The damage caused depends on the energy involved and on the sensitivity of the electronics systems. Ensure that lightning protection measures are taken to create a reliable repeater site. Protect all coaxial cables and power cables from the transients caused by lightning. Fit all cables with suitable lightning protection devices. For detailed information please refer to IEC 61024-1 and 61312-1 for international standards for protection of information systems against LEMP, Lightning Electromagnetic Pulse, including radio transmitters. They define proper planning, installation and inspection of effective lightning protection systems. Figure 4-8.

Packet Switched Modem Configuration (GSM/GPRS) NOTE: In case the network connection is not performed properly (using GPRS), it is necessary to telnet, SSH or serial into the controller and enter TRACE MODEM to see why modem is not initialized (wrong / missing PIN, wrong APN etc).  From the Remote communication menu, select ***: GPRS.  In the GRPS area, enter the following:  Access Point Name – customer’s Access Point name.  Click Apply.
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 36 Doc PN 0034B-UM Rev. 2.1 © Axell Wireless Ltd Circuit Switched Modem (PSTN/GSM) Using a circuit switched modem requires a landline connection be present at the site (for PSTN) or a SIM card supporting this feature (for wireless GSM). Communication Setup 1. From Device:Method select STD:DTC (Stadnard AT:DataCall). 2. In the modem initialization string type: AT+CBST=7,0,1. 3. Click Apply. Verify Circuit Switched Modem Functionality 1. Use the ACT RCD command via the Axell Shell or via Terminal to launch a modem restart (if logged in, restart will be performed on the first logout). 2. Dial the modem number (if PSTN) or the data number (if SIM card). 3. Verify modem LEDs are lit correctly (see section 8.1). 4. Use any ACT command using a Terminal to test connectivity and responsiveness. SIM-card Using Single Numbering Scheme If using SNS (Single Numbering Scheme), calls to the modem within the network are automatically classified as DATA. However, if calling from outside the network, you must first verify how its interfaces handle the VOICE vs. DATA bearing. This cannot be solved at remote level. The external network administrator must provide the above information. 6.6 Integration into the AEM When the repeater has been installed at site and the remote communication has been enabled, the repeater can be integrated to the Axell Element Manager. This is done by the
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd Doc PN 0034B-UM Rev. 2.1 37 operator of the AEM. After entering the telephone number to the repeater, the AEM dials up the repeater, downloads all the repeater parameters and statuses into a database. When all parameters have been downloaded, the AEM configures the repeater with the telephone number where alarms and reports should be sent, and optionally with a secondary telephone number where the repeater can dial in case connection to primary number fails. When heartbeat reports and alarms are sent from the repeater to the AEM also the latest information about the status and RF-configuration is included. This means that the AEM operator always has information about the current status in the AEM database (and do not need to call the repeater to find this out). NOTE: Once the repeater is integrated to the AEM, all changes to the repeater should preferably be done from the Axell Element Manager in order to ensure that the database always contains correct information.

AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 48 Doc PN 0034B-UM Rev. 2.1 © Axell Wireless Ltd LaptopLaptopRS232 cableControl ModuleGSM ModuleLMT Port8.3 Troubleshooting Remote Communication Please also refer to the document Common Command and Attributes for guidance. Since many networks have their own “personality”, performing first time configuration of the remote communication sometimes requires tweaking of the modem parameters. This section describes some trouble shooting techniques if configuring the repeater for remote access fails. The illustration below is a simplified schematic of the remote communication between a GSM modem in a repeater and an analogue modem. The analogue modem in the computer communicates with the Interworking Function Unit (IFU), which is the GSM network analogue network interface. The call is routed via the switch centre over the air interface to the data call number in the SIM-card of the GSM module. The Control Module is responsible for establishing connections with the Axell Element Manager, and to answer incoming calls to the repeater. As described in previous sections, the Control Module only accepts one login at a time, either via Local Maintenance port (LMT) or modem connection. Hence, when verifying the remote access of the repeater, it is important to log out from the repeater locally before trying to access the repeater remotely. 8.3.1 Direct Modem Access To allow for advanced trouble shooting of the communications, it is possible to connect directly to the modem by opening the repeater and connecting to the Control Module from a computer. Log in to the repeater, either with RMC, or with a terminal emulation program, such as HyperTerminal™. When the login is completed, select Terminal Mode, this will give access to the repeater command prompt in the same way as with HyperTerminal. When the repeater prompt is accessible, type in the command ACCESS MODEM <Enter>.
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd Doc PN 0034B-UM Rev. 2.1 49 When typing ACCESS MODEM, the controller will send all the characters that are typed directly out to the modem port. All characters replied back from the modem will go directly to the LMT port and back to the computer. To abort an ACCESS MODEM session, press three ‘-‘ in a row (all three within one second) to come back to the repeater command prompt. NOTE: When accessing the modem port the modem might be configured with “echo off”, meaning that the characters entered will not be echoed back to the screen. In order to enable “echo”, press Enter. Type ATE1 <enter> (invisible) The modem replies with OK indicating that the echo is enabled. All characters entered will now be echoed back to the terminal program. 8.3.2 Trace Modem For troubleshooting purposes it is possible to trace the actual progress of initializing the modem. This trace is useful when having problems with the modem initialization. Go to Terminal Mode and type TRACE MODEM To end session type CTRL-Z
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 50 Doc PN 0034B-UM Rev. 2.1 © Axell Wireless Ltd 8.3.3 Manually Answering Incoming Calls It is possible to manually answer incoming calls without involving the repeater software at all, to verify that the remote access and the network itself works as intended. In order to verify the remote communication, make sure to have someone stand by to dial up the repeater with a terminal emulation program, for example HyperTerminal™. Go in to Direct Modem Access as described earlier. When in direct access mode, ask the person standing by to dial up the repeater. As soon as a call is received, the text RING will repeatedly be displayed on the screen. Type ATA <enter> This will inform the modem to answer (ATtention Answer). When the connection is established, a connect message will be displayed including the connection speed. Sometimes the information comes together with some miscellaneous information, such as error correction protocols etc. NOTE:Make sure the remote peer dials the Data Call number If the voice number is dialed instead of the data number, or if the modem contains an illegal modem initialization string, the message OK or NO CARRIER will be displayed almost immediately. Try to change the modem initialization string. The modem initialization string mainly used to configure the remote communication is AT+CBST. Successful modem initialization strings used by Axell Wireless includes (most common first): AT+CBST=71,0,1;\Q3 AT+CBST=7,0,1;\Q3 AT+CBST=0,0,1;\Q3 AT+CBST=0,0,1;\Q3 AT+CBST=7,0,3;\Q3 Once the modem initialization string is entered, try again to dial up the repeater. For details on the different modem initialization strings, please refer to the modem’s user guide. If the setup is successful, the connect message will be brought up; CONNECT 9600 This means that an online connection is established to the remote peer. From now on, all characters typed on the keyboard will end up on the remote peer’s screen. Similarly, all characters typed by the remote peer will be displayed on the screen. In the example, the incoming call was successfully answered, and the remote user entered the text message. In order to come back to modem command mode, press +++ (three pluses) rapidly (within one second). Receiving OK means that the modem is back in command mode. Type ATH <enter> This terminates the connection to the remote peer. The message NO CARRIER will be displayed.
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd Doc PN 0034B-UM Rev. 2.1 51 8.3.4 Common Problems Problem 1 When enabling the remote access for the repeater, the modem fails to log in to the network. Solution Signal strength from the donor site is too low. The signal strength can be read directly from the modem. Go in to Direct Modem Access as described earlier. Use the command AT+CSQ (documented below) to read out the signal strength. In order to have good signal quality, Axell Wireless recommends that the signal strength should be better than -95 dBm. If signal strength is lower, try to adjust the antennas to get a better signal strength from the donor. Documentation of +CSQ command from a modem’s manual. In the example the reply to AT+CSQ is 0,7 meaning 7*2 dB above -113 dBm; the modem detects a signal level of -99 dBm.
AXELL D-CSR 3302 US VHF REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 52 Doc PN 0034B-UM Rev. 2.1 © Axell Wireless Ltd Problem 2a Repeater is configured properly, and answers the incoming call, but when trying to dial the repeater using an analogue mode, no modem handshaking is heard from the dialing modem. Problem 2b When dialing the repeater, the repeater answers the incoming call, but no connection is established, and after a while the repeater disconnects the call. Solution The most common cause is that the number called is the voice number of the SIM, not the data number. Therefore, make sure to dial the data number. If data call is used, the problem probably is an illegal modem initialization string. In order to change the modem string, go to the repeater command prompt. Try changing the modem initialization string and log out to let the controller reinitialize the modem. If problem remains, try a few different modem initialization strings. Axell Wireless has been successful with the following modem initialization strings: AT+CBST=71,0,1;\Q3 AT+CBST=7,0,1;\Q3 AT+CBST=0,0,1;\Q3 AT+CBST=0,0,1;\Q3 AT+CBST=7,0,3;\Q3 Please refer to the modem manual for detailed description of the modem initialization strings. Problem 3 It is possible to call the repeater from another GSM mobile, but not from an analogue modem. Solution This problem is most likely related to the modem configuration and/or the configuration of the IFU unit. Try to decrease the communications speed and make sure that the modem error correction is supported by the IFU. Verify the IFU configuration to see if there are any known problems with the modem connections. Problem 4 When dialing the repeater, or when the repeater is dialing the Element Manager, the connection is terminated before the handshaking is completed. Solution When a repeater is answering an incoming modem call, or calling up the OMC to deliver an alarm or a report, the repeater will wait a configurable number of seconds for the call to be established. If no communication is established within this time, the call will be hung up. If this interval is set too low, the handshaking is terminated too fast. In the RMC, verify the Modem Connect Time to see that it is set to at least 30 seconds.
