MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL 1 1.1 Repeater Technology Basic Repeater Features A basic feature of a mobile communication system is to transmit RF signals between base stations and mobile radio equipment. When there is a blocking object, such as a mountain or a building, preventing the base station signal to reach the mobile equipment, a repeater can be used to extend the base station’s coverage area.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL where the BTS signal strength is large enough to be usable by the system. 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. The signal generated by the BTS is picked up at the repeater site via the donor antenna.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL 1.2.3.1 Donor Unit There are two types of donor units – single donor (SD) and double donor (DD). A single donor (SD) unit has one input connector. The input signal from the BTS is split in two within the repeater unit. In the opposite direction – in the uplink – the signals are combined within the repeater before being sent to the BTS. A double donor (DD) unit has dual inputs.

If several repeaters are connected to the same OMU the total gain in each chain should be slightly lower than 0dB not to insert too much noise into the BTS. Note! 5.6.2 For in-depth instructions for commissioning of an OMU-Repeater system please contact your Axell Wireless representative.

For repeaters that are to be used as slaves in an OMU-Repeater system all report configurations are done from the OMU. 5.7 Set Up Remote Communication Note! If the repeater is fibre fed and is set up as a slave- this section is not relevant since the remote communication is handled by the node master – in most cases an OMU.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL 5.7.1.2 Monitoring Modem Connection The Control Module constantly monitors the status of the modem connection to ensure that it is working properly, and that the modem is logged in to the network. In case the modem is not registered to the network, or the Control Module cannot properly communicate with the modem, a power cycling of the modem is initiated, after which the modem will reinitialized. 5.7.1.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL recommendation is AT+CBST=71,0,1;\Q3. If remote communication cannot be established try 7,0,1 or 0,0,1 or 7,0,3. For more information please refer to the section on Troubleshooting Remote Communication. Tick “Enable Automatic Modem Power Cycling” for the modem to be power cycled once every 24 hours. Set the time at which the modem should be tested. This function ensures that the repeater always is logged in to the network. 5.7.2.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL Each parameter is described in Common Commands and Attributes, section 14 GPRS Configurations. Set the Access Point Name. It needs to be defined by the telecom operator Set Maximum Receive Unit and maximum Transmission Unit. These differ depending on access type: 576 for GSM, 1476 for EDGE and 1500 for WCDMA. Click on Close, and then on “Yes”. Wait for the modem to restart. This can take a few minutes.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL A fallback functionality is available, which means that the Control Module falls back to the primary address after a configurable number of minutes. If this interval is set to 0, the fallback will not be performed. A user can always force the Control Module to fall back to the primary address.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL Note! It is very important to dial the data number of the SIM. In case the voice number is dialled, the call is answered, but almost immediately the call will be hung up. 5.7.2.5 SIM-card Using Single Numbering Scheme If the network is configured using Single Numbering Scheme (SNS), some special considerations apply.

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™.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL 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.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL 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. 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 dialling modem.
MBF, Multi Band Repeater PRODUCT DESCRIPTION AND USER'S MANUAL 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.
