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). Alvarion developed a unique DAS solution for improving in-building wireless coverage in commercial buildings such as airports, stadiums, shopping malls, hotels, office buildings and residential areas. Such locations suffer from wireless coverage problems such as interference, attenuation, and multi-path due to their height and build. The solution is installed using a hybrid fiber and TV type coaxial cables. BreezeCELL’s unique flat architecture makes it extremely cost effective. The solution can also be installed using existing coax cables infrastructure, used to distribute TV signals within the building. Alvarion believes that utilizing the already installed TV infrastructure is the most cost effective means of providing these services. Value proposition Affordable active Distributed Antenna System Very low installation cost Unique MIMO on a single cable solution Plug and Play - very fast and flexible installation process Multi-Operator, Multi service Easy design and fine tuning Fast ROI The Concept Indoor wireless coverage is traditionally done via external macro cells. In many cases coverage is problematic due to interference, attenuation, multi-path and other issues. BreezeCELL distributes the cellular signal throughout the property over a combination of fiber and 75 ohm coax to active remote units and antennas located throughout the building area. On the other hand, almost all buildings are equipped with coax cables infrastructure, used to distribute TV signals within the building. Alvarion's solution can use this existing cabling infrastructure through unutilized bandwidth on the coax cables to bring wireless services into the indoors environment. Alvarion's technology enables servicing multiple operators and technologies (i.e GSM, UMTS, CDMA, WiMAX, iDEN) over the same infrastructure in order to increase the utilization of the cable infrastructure. BreezeCELL is a forward compatible system and fits current and future protocols (LTE, etc) and has a unique MIMO solution on a single cable support. BreezeCELL In-building Cellular Solution for Commercial Buildings 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. The combined RF signal is then converted to an optical signal which is being transmitted via the fiber link. At the coverage area the optical signal is being converted back to RF and propagated along the coaxial network down to the remote units. If required and in order to overcome the coax cable attenuation, a wire amplifier is used to boost the signal. Remote units are connected to the cable and transmit via a built-in antenna (or an external antenna) the wireless signals indoors at their original licensed frequency. In the case of TDD transmissions such as WiMAX and LTE, the BreezeCELL equipment converts the TDD signal to FDD at both ends of the system (Headend and Remote). TDD synchronization is run over the system. It is important to note that there is no modification to the original signal generated by the Wireless equipment. BreezeCELL is an active DAS, carrying the signal to the remote small antenna (Remote unit) where it radiates in its original form. The following diagram illustrates the BreezeCELL network: Fiber BTS/Node B UDC/OCD (RF <> Optic) Coax OCN Amplifier (Optic <> RF) (optional) Remote Units Figure 1: BreezeCELL Architecture 3.2 Existing Cable TV Network A typical in building TV coax network is built as a tree and branch architecture. TV signals are delivered from a common source (which can be a terrestrial antenna, CATV or satellite dish/receiver) to TV outlets within the building. In order to compensate for losses in the coaxial cables a set of amplifiers are installed at various locations throughout the network to increase the signal gain. The signal is distributed to branches using taps and to the outlets using power dividers. Amplifiers can also be found in the branches. BreezeCELL 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. All other elements namely coax cables, connectors, taps, power dividers and outlets are capable of handling the required frequencies. 3.2.2 BreezeCELL Solution Wireless equipment is installed at the entry point of the TV signals to the building. The TV signals entry point may be a terrestrial antenna, a satellite dish or CATV feed. In some cases, like hotels, the source of the TV signals may be a stack of CATV or satellite receivers and a VOD/PPV system. The wireless equipment may be a microcell, a picocell or a wireless repeater. The wireless signal is shifted in frequency to the Alvarion band and then combined with the TV signals. Since the Alvarion band is above the TV signal band, there is no interference between the two signals. The combined signal is propagated along the coaxial network down to the TV outlets. In order to overcome the frequency limitation of the cable amplifier a bypass circuit is used to separate the wireless signal, amplify it and then recombine the frequencies. At the end user’s TV outlet a small CPE called Remote is connected which transmits the wireless signals indoors at their original licensed frequency. In the case of TDD transmissions such as WiMAX, the BreezeCELL equipment converts the TDD signal to FDD at both ends of the system (Headend and Remote). TDD synchronization is run over the system. It is important to note that there is no modification to the original signal generated by the Wireless equipment. BreezeCELL is an active DAS, carrying the signal to the remote small antenna (Remote) where it radiates in its original form. The following diagram illustrates the BreezeCELL network overlaying the cable TV infrastructure: BreezeCELL In-building Cellular Solution for Commercial Buildings UDC Software Configuration Tool Figure 3: BreezeCELL Architecture 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. The purpose of BreezeCELL’s Head end equipment is aggregating wireless services signals, converting them into the correct frequency range and combining them on the coaxial network. Remote monitoring and control of the Remotes is performed using the monitoring system in the headend. The wireless equipment (microcell or repeater) is also installed at the same location. 4.1.1 UDC – Up Down Converter The wireless native RF signal is inserted into Alvarion Up/Down Converter (UDC). The UDC converts the original wireless signal into the 960 – 1155 range. In TDD networks (WiMAX) the UDC also converts TDD signals to FDD. The output of several UDCs can be aggregated together by the CCD (see 4.1.2 below) in order to combine several operators and technologies or aggregate traffic. BreezeCELL 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. 960÷ 1155 MHz Native RF Cell UDC CCD Coaxial Cable (Up and Down) 10 MHz Microcell or Repeater Figure 4: Head End Equipment 4.1.3 Monitoring & Control A communication link exists between the Monitoring software residing on a PC at the headend and the remotes. The monitoring & control systems enables the user to remotely configure the Remotes operating frequencies, turn a Remote on/off and monitor various Remote parameters. Alarms generated at the Remotes will be communicated to Monitoring and be displayed for the user. 4.2 Optical Network Equipment 4.2.1 OCD – Optical Cable Distribution The OCD has the same functionality of the CCD. OCD combines the RF inputs and outputs of several UDCs into a single fiber connection. 4.2.2 OCN – Optical Cable Node A fiber is pulled in between the BTS location and the main coverage area, where coax is being laid. The optical signal is converted to RF signal using the OCN which is an RF optic transceiver. 4.3 Coaxial Network Equipment The purpose of the bypass infrastructure is enabling the transfer of the 960 -1155 MHZ frequency band over the standard cable TV Coax amplifiers. The cable TV amplifiers are the only element in the network which does not handle this frequency range and therefore the higher frequency signal should bypass those amplifiers and be amplified separately. The amplifiers are bi-directional and carry both the forward and return wireless signals. BreezeCELL 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. The design of the bypass filter is based on a diplexer which passes the standard cable TV signals with low attenuation and provides the required separation between them and the Alvarion signals. For self powering systems the diplexer also samples the AC signal that runs on the coax and uses it to power the Alvarion amplifier. A bypass filter is used for splitting the signals before amplification and for combining the wireless and cable signals after amplification. 4.3.2 Bi-directional Amplifier This element compensates for the wireless signal losses that result from coax cable attenuation. The amplifier is a low power amplifier in order to draw minimal current from the cable network. 4.4 Remote Unit The Remote is an active unit. The purpose of the Remote is to take the RF signals that are propagated via the cables, convert it to the native wireless frequency and transmit it in the air inside the building. The Remote contains a miniature UDC for frequency conversion, a transmitter and an internal antenna (external antenna connection is available as well). The Remote receives power through the cable and can be installed as a self contained unit. The Remote units can be single or dual band The Remote can operate in MIMO configuration for 4G networks. BreezeCELL In-building Cellular Solution for Commercial Buildings 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. Other operators and technologies can be added MIMO Support The system supports SISO or 2x2 MIMO (A and B). MIMO is supported using a single cable. MIMO channels are frequency duplexed within the BreezeCELL band and sent across the infrastructure to the remote units. At the remote each channel is separated and transmitted from a dedicated antenna. Downstream Ch1 Ch2 Upstream Ch1 Ch2 Downstream Ch1 Ch2 Upstream Ch1 Ch2 MIMO Remote BS Figure 6: MIMO Utilization Monitoring & Control Monitoring provides the network operator with the ability to remotely monitor and if required configure the BreezeCELL Remotes. The Monitoring System comprises monitoring agents in the Remotes and a web based server co-located with the cable headend equipment. The agents are responsible for monitoring the status and configuring the Remotes while the server is responsible for displaying the data and interfacing to the user in a friendly manner. The traffic between the monitoring system and the agents is carried over a proprietary communication modem channel that is established between the Remote agents and the server via the CCD. This channel is carried over the CATV network using dedicated bandwidth within the Alvarion band (960 MHz to 1155MHz). The physical layer of the channel is implemented by a two-way modem, an integral part of the agent. The MAC (Media Access Control) layer of the communication channel controls the access scheme over the shared CATV medium. A proprietary protocol is used over this communication channel in order to minimize the CPU performance and memory requirements of the agents. During normal operation, the monitoring system receives failure messages from the Remotes and triggers a visual alarm on the screen with identification of the faulty Remote. BreezeCELL 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. A similar modem resides in the controller of every Remote which enables the monitoring and configuration of the Remote. UDC RF CCD Remote Modem Modem RF + Monitoring signal RS-232 Figure 7: Monitoring Architecture The Monitoring PC serial port is connected via an RS-232 cable to the CCD. The user has a Web based GUI and the PC translates the user operations into a set of commands transmitted by the modems between the PC and Remotes. The PC polls all the Remotes at regular intervals to check their operational status and updates the database with the changes. The Remotes constantly monitor their internal status. In case of a fault the Remote will transmit a message to the PC to indicate the fault. The PC will update the database and GUI. Installation Requirements and Procedures 8.1 CATV System (if applicable) 8.2 BreezeCELL Coax TV plant supporting 750/860MHz transmissions Headend (Equipment Room) Equipment room 19” rack space for the following: CCD – 2 U UDC – 1 U (for each UDC) monitoring PC – 1 U Available power outlets for CCD, UDCs, Socket outlets should be installed near the equipment and shall be easily accessible 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. Otherwise connecting cables should be prepared. 8.3 Equipment should be used in a RESTRICTED ACCESS LOCATION only Coax Plant (if applicable) Available power outlet next to each TV amplifier Socket outlets should be installed near the equipment and shall be easily accessible Additional two pole disconnect device (disconnect all poles simultaneously) should be provided in the building installation 8.4 Available space for 2 diplexers and 1 amplifier next to each TV amplifier Equipment should be used in a RESTRICTED ACCESS LOCATION only Rooms (in case of CATV plant) TV outlet Available power outlet next to each TV outlet Headend Equipment Installation 9.1 Connector Information 9.1.1 UDC BTS/Node B: SMA female 10 MHz input: BNC female Alarm output: D-type, 9 pin 9.1.2 CCD UDC Up link: SMA female UDC Down link: SMA female 10 MHz output: BNC female RF output: F type female BreezeCELL 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. Configuration can be done externally, however it is advisable to leave room above the UDCs to allow for cover opening. Connecting the BreezeCELL Equipment 1. Connect the DL port of the UDC to the CCD Down Link port using a SMA/SMA cable. (Figure 11-1) 2. Connect the UL port of the UDC to the CCD Up Link port using a SMA/SMA cable. (Figure 11-2) 3. Connect the 10 MHz in port of the UDC to the 10 MHz output port in the CCD using a BNC/BNC cable. (Figure 11-3) 4. Repeat steps 1 – 3 for all UDCs 5. After power up, all LEDs should be green. Figure 8: Headend Equipment Connections 9.4 BreezeCELL Connecting the Monitoring System 1. Connect the PC to the monitor and both to the power outlet 2. Connect the Dry contacts interface Advantech USB-4761 to the USB port at the back of the PC 3. Connect the PC to the CCD serial port (on the back) using a DB9 serial cable (male to female) 4. Connect the female side of the DB9 cable to the PC serial port (light blue colored with the symbol IOIOI) 5. Connect the male side of the DB9 cable to the serial port on the back of the CCD 10 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. Connect an appropriate cable between the alarm output and the BTS alarm input (or other input source). Figure 9: UDC Alarm Output 9.5.2 Monitoring The system uses an Advantech USB dry contacts adaptor for alarm indications. Relay #0 – provides alarm for a single remote unit failure Relay #1 – provides alarm for a multiple remote units failure Single remote unit alarm: For a Normally closed operation connect NC0 and COM0 to the relevant BTS alarm port Multiple remote units alarm: For a Normally closed operation connect NC1 and COM1 to the relevant BTS alarm port 9.6 Connecting the Base Stations UDC input power range is +10 dBm to +33 dBm. The BTS/Node B output power should be adjusted to meet this requirement. In case BTS power exceeds the requirement an external attenuator should be connected Note: Only the downlink path should be attenuated! In case of a combined up/down links, it is advisable to split between uplink and downlink paths, and place the attenuator on the downlink path only. Connect the output of the BTS/Node B to the appropriate BTS/Node B connector in the relevant UDC (An N-to-SMA or other adaptor might be required according to the BTS output connector). 9.7 UDC Configuration UDCs are pre-configured at the factory. In case a change of configuration is required the units are capable of configuring the BTS attenuation and the gain control. Setting requires removal of the UDC cover. BreezeCELL 11 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. The output level of the downlink cellular signal in the Alvarion band should be 0±1 dBm. The following figure demonstrates the location of the attenuator: Figure 10: BTS Attenuator 9.7.2 Gain Configuration The UDC has internal attenuators that allow you to control the Pilot signal level and up link and down link gains 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. All signals are pre-configured according to network parameters. BreezeCELL 12 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). Frequency Configuration UDC frequency configuration is required in the event the UDC is not pre-configured with the correct operating frequencies. Using the configuration software is described in appendix A. 9.8 Pilot Master/Slave Configuration When working with multiple UDCs only one pilot signal should be generated. Therefore one UDC should be configured as Master and the rest as Slaves. Note: The power to the UDC and CCD units should be disconnected before performing the following procedure. Locate the Master/Slave jumper on the further left corner of the main UDC circuit board. There are three pins. Place the jumper (J9) on the left and middle pins for Master.
