This fiber optic laser transmitter contains a class IIIb laser product as defined by the US Department of Health and Human Services, Public Health Service, Food and Drug Administration. This laser product complies with 21 CFR, Chapter I, Subchapter J of the DHEW standards under the Radiation Control for Health and Safety Act of 1968. The laser module certification label is located on the equipment enclosure and it also shows the required DANGER warning logotype (as shown below). 7 EMS Wireless EkoLink Plus Fiber Optic DAS Operators Manual The EMS Wireless laser products are used in optical fiber communications systems for radio frequency and microwave frequency analog fiber optic links. In normal operation, these systems are fully enclosed and fully shielded by the hermetically sealed laser metal package. Laser bias current is limited by the internal control circuitry. The transmitters are coupled to glass fiber and have 1310/1550 nm optical output wavelength with typically 0.5 to 20 mW output depending on the model. The optical radiation is confined to the fiber core. Under these conditions, there is no accessible laser emission and hence no hazard to safety or health. Since there is no human access to the laser output during system operation, no special operator precautions are necessary when fiber is connected to the transmitter and receiver. During installation, service, or maintenance, the service technician is warned, however, to take precautions, which include not looking directly into the fiber connector or the fiber that is connected to the fiber connector before it is connected to the fiber optic receiver. The light emitted from the fiber optic connector or any fiber connected to the connector is invisible and may be harmful to the human eye. Use either an optical power meter or an infrared viewer or fluorescent screen for optical output verification. All handling precautions as outlined by the FDA and ANSI Z136.2 and other authorities of class IIIb lasers must be observed. Do not attempt to modify or to service this Product. Contact the EMS Wireless Customer Support Department for a return authorization if service or repair is necessary.

Remote alarming through the hub unit. This allows technicians to monitor system performance remotely via telephone line and computer with modem and terminal software. Truly plug and play operation, with a totally automatic software set-up sequence, in the hub and all remote units, or manual control capability for specific setups. Remote units have true automatic gain control to allow compensation for RF source variations, optical loss, or other variations in power level. The monitoring and control of the system occurs with a direct connection to a laptop computer, wireless modem, or via a wireline option for remote access. The system uses single mode fiber optic cable to connect the hub to the remote(s). This eliminates the large signal losses inherent in long runs of coax or CAT 5 (twisted pair) cables used in other systems. For this reason, very long (up to five kilometers) fiber optic cables can be used to provide coverage very far away from the hub unit in large complexes of buildings or large outdoor areas. The unit operates with +20 dBm RF donor signal level, which is conveniently obtained via direct coaxial cable launch from a BTS with appropriate attenuators. The advantage of using a dedicated micro BTS for the DAS is dramatically increased system capacity within the covered building. The BTS interface is a pair of coaxial connections to independent receive and transmit ports. Optionally an interface is available to connect to a duplexed BTS output. The Eko Link Plus is a band selective Fiber Optic Distributed Antenna System

(DAS), designed to be fully compliant with GSM-AMPS-TDMA-CDMA standards. Standard downlink path output power is 2 watts (+33 dBm), 4 watts (+36 dBm), 8 watt (+39 dBm) or 20 watt (+43 dBm) composite. The uplink path provides an approximate 3 dB system overall gain. The EkoLink Plus can be optionally configured with two independent passbands for each radio frequency path. This means that two PCS bands can be covered 13 EMS Wireless EkoLink Plus Fiber Optic DAS Operators Manual with one system. At Cellular 800 MHz, A + A + A or B + B extended band segments can be covered with one unit. The EkoLink Plus system will support up to four remotes per hub or two remotes with the diversity receive option. Diversity receive is accomplished by processing an additional receive signal (using a second receive antenna) at a particular remote unit. This signal is sent via fiber optic cable back to the hub unit. This allows for spatial or polarization diversity to be supported, similar to a BTS. Optionally, Wave Division Multiplexing (WDM) can be added to the system, allowing for a single fiber optic cable from the hub to each remote, which handles both uplink and downlink signals. An optional wireless or wireline modem can be equipped at the remotes and or at the hub location. The modem allows for remote alarm and control of the units via MUM software or a laptop computer. More specific technical features can be found in the Technical Specifications and the Technical Description sections of this Operators Manual. Figure 1 shows a mechanical diagram of the Hub in the rack mount configuration. Figure 2 shows the hub in the optional waterproof housing, and Figure 3 shows the remote unit. 14 Operators Manual 6.968

Once the system is configured, it can be controlled using an optional telephone line interface. The following is a summary procedure for configuring the EkoLink Plus using its built-in automatic software. More detailed software commands for specific configurations can be found later in this manual. 23 Operators Manual EMS Wireless EkoLink Plus Fiber Optic DAS 3.1 Automatic Set-up:

3.1.1 Hub Set-up:

WARNING!

DO NOT TURN ON THE POWER UNLESS THE REMOTE UNIT(S) ARE CONNECTED TO ANTENNAS OR ATTENUATORS ON THE SERVER ANTENNA PORT!

Connect the computer using an RS232 serial port with a DB9 male connector (on cable end for the repeater) to the hub status and control module in the repeater. Use a terminal emulation program, such as ProComm or HyperTerminal, set to:

VT-100 series terminal emulation 9600 baud 8 bit 1 stop bit no parity no flow control (flow control = none) Turn the hub on, followed by each remote unit. Press the Enter key on the computer to initialize the login screen. Note: Login may take several seconds if the repeater is in active communications mode. To bypass sending all of the alarms, press ENTER as soon as the date and time appear on the screen. Note: For assistance, type HELP for a list of available commands. Login to the system using one of the default Usernames and Passwords shown in Table 1 below. Both the Username and Password are CASE SENSITIVE. Do not use the number pad on the keyboard to input numbers. 24 EMS Wireless EkoLink Plus Fiber Optic DAS User Name USERNAM1 USERNAM2 USERNAM3 USERNAM4 Table 1: Default User Names and Passwords Password PASSWRD1 PASSWRD2 PASSWRD3 PASSWRD4 Authority Read/write Read/write Read only Read only Operators Manual Change the default Username and Password. Each Username and Password can have a maximum of eight characters. For example, to change the second Username and Password, enter the following two commands:

SET PWD#[password]<enter>

SET UID#[password]<enter>

Type RESTART followed by the enter key. This command will re-set all the software settings and allow the set-up routine to measure the RF signal levels and set the attenuators appropriately. Type EXIT to log off the EkoLink Plus hub. Disconnect the RS-232 cable from the hub. 3.1.2 Remote Set-up:

Move the computer and serial cable to each of the remote units. Log on to each remote unit using the same procedure as above for the hub unit. At each remote, look at the status screen. If necessary, adjust the peak RF output level by using the SET PEAK command. For example, SET PEAK 24 This command will set the RF output power to 1 dB less than the command value. In this example, the RF output from the remote unit will be +23 dBm. Type the RESTART command. This command should initialize the software sequence, and set up the remote so it will transmit at the power level set in the previous step. 25 Operators Manual EMS Wireless EkoLink Plus Fiber Optic DAS Note: To transmit the minimum necessary power, the repeater automatic setup will set the attenuation for maximum. Then, attenuation levels are reduced until the desired output power is achieved. The uplink (reverse) attenuation is automatically set equal to the downlink (forward) attenuation to maintain path balance. The repeater should now be properly configured for operation. 3.2 Manual System Set-up:

There is an extensive list of software commands that may be used with the EkoLink Plus. These commands will override the automatic system set up feature and will require the user to manually adjust both the down link and up link attenuation. The complete list of commands may be found in Section 8. 4.0 System Optimization Now that the EkoLink Plus is providing the desired output power, the local repeater system needs to be optimized. The neighbor lists of the donor base station should be reviewed. The repeater uses highly selective Surface Acoustic Wave (SAW) filters, which have a group delay of approximately 3 microseconds. Since the propagation delay of free space is 5.4 microseconds per mile, the delay is equivalent to approximately 1/2 of a mile of free space propagation. The neighbor lists of the donor base station and the base stations surrounding the area served by the repeater need to be adjusted. For example, in Figure 10, a repeater or DAS extends the coverage of BTS1 to a new area. BTS1 is now neighbors with BTS4 and BTS5, whereas without the repeater, BTS1 is neighbors with just BTS2 and BTS3. Thus BTS4 and BTS5 must be added to BTS1s neighbor list, and BTS1 must be added to BTS4s and BTS5s neighbor lists. A drive test of the coverage area should be performed to verify the final setup. 26 EMS Wireless EkoLink Plus Fiber Optic DAS BTS 1 BTS 2 27 Operators Manual BTS 5 COVERAGE AREA REPEATER BTS 4 BTS 3 3.2.1.1.1.1 Figure 10.

(Simplified Block Diagram) Figure 13: EkoLink Plus Remote Unit Block Diagram 5.1 Remote Unit 5.1.1 Channelizer Modules Each path in the channelizer module consists of an LNA, a baseband down converter with SAW (Surface Acoustic Wave) filters, a baseband up converter, and a post amplifier. The module includes power level control functionality. The uplink path includes the power amplifier, while the downlink path has the power amplifier external to the channelizer. 5.1.2 Power Amplifier The power amplifier is designed for an output power of 2 watts (+33 dBm), 4 watts

(+36 dBm), 8 watts (+39 dBm) or 20 watts (+43 dBm) composite. The power amplifier is designed to meet industry standards for Adjacent Channel Power Ratio (ACPR) and spectral re-growth, and is compliant with all FCC required standards. 5.1.3 Power Supply Module The power supply is designed for an input voltage of +26VDC or optionally 90 130 VAC, or 187 - 265 VAC. 30 EMS Wireless EkoLink Plus Fiber Optic DAS 5.1.4 Duplex Filter Operators Manual The transmit and receive RF signals are combined with duplex filters operating in the desired frequency band. The filter consists of comb-line cavity bandpass filters, which provide excellent isolation against out-of-band signals. 5.1.5 Status and Control Module The status and control module, contained within the channelizer, enables monitoring and control of the repeater. This module determines the status of the channel module and identifies failure conditions. When an alarm occurs, the module can send a message to a PC over a serial data link. The PC connection uses an RS232 serial port interface which connects to a laptop computer using Windows HyperTerminal or another similar terminal emulation program. Also, the status and control module sends and receives channel and amplification data on the addressed channel module when connected to a cellular modem. Monitoring and control is possible through the MirrorCell Unit Manager (MUM) using a wireless or wired modem connection. The MUM is not accessible with a direct hard-line

(local) connection to the status and control module. 5.1.6 Interconnect Module The Interconnect Module provides interface and power connection to all of the modules in the remote unit. The control module, located in the channelizer, monitors each of the major modules by monitoring status and control lines distributed through the interface module. DC levels required by the channelizer are also regulated on the interconnect module and distributed to the channelizer. 5.1.7 Fiber Optic Transceiver The Fiber Optic Transceiver modulates or demodulates the RF signal from the optical signal and provides interconnection to the optical fiber. Interconnection is provided via the interconnect module with the control module located in the controller. The control module transmits alarm status to the Hub Unit by pulsing the laser. This is received at the Hub where the alarm status is displayed or is monitored on a remote computer. 31 EMS Wireless EkoLink Plus Fiber Optic DAS 5.2 Hub Unit A block diagram of the hub unit is shown in Figure 12. 5.2.1 Hub Interface Module Operators Manual The Hub Interface Module provides the RF interface control for the uplink path, control of the optical lasers for signaling the remote status, interface to the controller module and wireline modem, and relays for alarm and control status. In addition, the primary power conversion is done in the hub interface module to provide all of the required voltages from an input supply voltage of 24 VDC. 5.2.2 Fiber Optic Transceiver The Fiber Optic Transceiver modulates or demodulates the RF signal to the optical signal and provide interconnection to the optical fiber. The control module transmits alarms and control information to the remote repeater unit by pulsing or turning off the laser. This, in turn, is received at the remote repeater detector which provides the desired alarm and or control command. The Hub can be equipped with up to four fiber optic transceivers to support four remotes or two remotes with diversity receive. 5.2.3 Hub Control Module The Hub control module enables monitoring and control of the hub and repeater. This module determines the status of the hub and repeater and identifies failure conditions. When an alarm occurs, the module can send a message to a PC over a serial data link. The PC connection is through an RS232 serial interface to a laptop computer equipped with Windows HyperTerminal or a similar terminal emulation program. Also, the status and control module sends and receives channel and amplification data to a remote location when connected to a wireline or wireless modem. Monitoring and control is possible through the MirrorCell Unit Manager (MUM) using a wireless or wired modem connection. The MUM is not accessible with a direct hard-line

(local) connection to the status and control module. 5.2.4 Hub Power Supply Module (Optional) The 115/230 VAC power supply module provides an output nominal voltage of 24VDC to the hub interface module when battery back up is not required. 32 EMS Wireless EkoLink Plus Fiber Optic DAS 6.0 EkoLink Plus Specifications 6.1 EkoLink Plus RF Specifications Operators Manual The RF Specifications are shown in Table 2 below.
