In-building Cellular Solution for Commercial Buildings 1 UDC Software Configuration Tool Introduction Indoor wireless coverage is one of the most challenging areas in the wireless industry. Alvarion develops innovative communications equipment, infrastructure and products – enabling wireless operators and property owners to deliver high quality indoor wireless services using a Distributed Antenna System (DAS).
In-building Cellular Solution for Commercial Buildings 3 BreezeCELL Architecture 3.1 Typical Network UDC Software Configuration Tool A wireless signal source (BTS/Node B/, Micro, Pico, Femto, Repeater) is installed in a central point in the building. Cabling infrastructure (fiber and coax) is installed according to a pre-designed RF coverage plan. The wireless signal is shifted in frequency to the Alvarion intermediate band and then combined in the RF level.
In-building Cellular Solution for Commercial Buildings UDC Software Configuration Tool Figure 2: Typical Cable Network 3.2.1 Frequency Limitations In order to pass through frequencies of 960 to 1155 MHz we need to examine the frequency limitations of the coax network elements. The only limiting element in the coax network is the amplifier used to boost the signal which is bypassed by the DAS system.
In-building Cellular Solution for Commercial Buildings UDC Software Configuration Tool Figure 3: BreezeCELL Architecture 4 BreezeCELL Network Elements The BreezeCELL network is composed of three parts: BreezeCELL Head end equipment, Coaxial Network equipment and Customer Premises (or end user) Equipment. 4.1 BreezeCELL Head End Equipment The BreezeCELL head end equipment is co-located with the TV signal source of the building.
In-building Cellular Solution for Commercial Buildings 4.1.2 UDC Software Configuration Tool CCD – Coax Cable Distribution The CCD combines the RF inputs and outputs of several UDCs into a single coaxial connection. The CCD also provides a reference clock for all UDCs by supplying them an accurate 10 MHz clock signal. Through the CCD the system monitoring signals are sent to the network elements. A single CCD can support up-to 8 UDCs.
In-building Cellular Solution for Commercial Buildings UDC Software Configuration Tool BreezeCELL’s coaxial bypass has very low power consumption and can be fed from the electrical grid or from AC voltage sent over the coax plant. Alvarion’s Amplifier Bypass Bypass TV Amplifier Figure 5: Bypass Infrastructure 4.3.1 Bypass Filter - Diplexer The Bypass filter is a passive element that separates the lower frequency cable TV signals 5-860 MHz and the higher Alvarion's frequencies of 960- 1155 MHz.
In-building Cellular Solution for Commercial Buildings 5 UDC Software Configuration Tool Frequency Allocations The up and down links of 75 MHz can be split and shared between several operators and technologies. A typical GSM operator requires 10 MHz and a typical UMTS operator 5 MHZ. Frequency allocation planning is done based on the required services and technologies. A typical example is a combination of GSM and UMTS on a single network. Together they occupy 15MHz out of the available 75 MHz.
In-building Cellular Solution for Commercial Buildings UDC Software Configuration Tool The monitoring system provides the user with a user friendly GUI. Using the GUI, the user is able to send commands to the Remotes (e.g. turning the Remote on and off), query for the status, and remotely configure (e.g. setting frequencies). 7.1 Monitoring Elements A proprietary modem is located in the CCD which is able to communicate with all the Remotes.
In-building Cellular Solution for Commercial Buildings UDC Software Configuration Tool Additional two pole disconnect device (disconnect all poles simultaneously) should be provided in the building installation Monitoring system comprise of a Pizza box rack mounted PC. In case remote access is required, a TCP/IP link should be available as well. It is advisable that the BreezeCELL equipment will be co-located with the cellular BTS/Repeater and the TV headend.
In-building Cellular Solution for Commercial Buildings 9.2 9.3 UDC Software Configuration Tool Rack Installation The CCD is a non-configurable unit and therefore should be installed as the bottom unit. The UDCs are configurable units (Gain and Attenuation controls). In general UDCs will be shipped pre-configured from the factory. In case a configuration is needed the box’s top cover needs to be opened.
In-building Cellular Solution for Commercial Buildings 9.5 Connecting External Alarms 9.5.1 UDCs UDC Software Configuration Tool Each UDC is equipped with an external alarm output at the back of the unit. Any UDC failure will light the Alarm LED on the front panel and trigger the dry contact whose output is at the back. The alarm is normally closed and will open once triggered or when there is no power to the UDC. Alarm output is at pins 2 and 3 of the 9 pin D-type connector.
In-building Cellular Solution for Commercial Buildings 9.7.1 UDC Software Configuration Tool BTS Attenuation Setting The UDC input power is limited. An internal attenuator allows inputs of +10 dBm to +33 dBm. In case the output is larger a separate attenuator on the downlink only is required. Switches represent values of: 1, 2, 4, 8, 16 dB. The left most switch has the highest attenuation – 16 dB. The right most switch represents the least attenuation – 1 dB.
In-building Cellular Solution for Commercial Buildings UDC Software Configuration Tool Figure 11: Gain Configuration If configuration is required: 1. Measure the signal at the UDC DL out port and configure the Pilot signal (962 MHz) to be 0 ± 1 dBm. 9.7.3 2. Measure the cellular downlink signal at the UDC DL out port and adjust it to be 0 ± 1 dBm. 3. Measure the signal at the UDC UL in port and adjust the uplink cellular signal so there is a 0 ± 5 dB end-to-end Gain (Remote Unit to UDC).
In-building Cellular Solution for Commercial Buildings UDC Software Configuration Tool Figure 12: Master/Slave Configuration 9.9 Measurements Required test equipment is a spectrum analyzer (capable of measuring both the cable and wireless frequencies). In case a BTS/Node B is not available, a signal generator can be used to simulate the signal. Connect the spectrum analyzer to the DL OUT port of the UDC and verify: 9.10 1. Pilot signal at 962 MHz at a 0 ± 1 dBm level. 2.

Connect the CABLE port the to the building coax network input Note: The diplexer AC port will be in use only when the coax network is self powered by a 60 VAC source. 9.
In-building Cellular Solution for Commercial Buildings 10 UDC Software Configuration Tool Coax Network Amplifier Installation (if applicable) The coax plant includes amplifiers that compensate the TV signal for the cable loss. A wireless amplifier should be installed in parallel to each TV amplifier. A set of two diplexers (bypass filters) and an amplifier is required for every TV amplifier. 10.1 Connections All connection are done using an F-male to F-male cable 1.
In-building Cellular Solution for Commercial Buildings 10.2 UDC Software Configuration Tool Testing and Measurements 1.
