System Description Introduction TDD Mini Repeater: BDA-TDD-25-16-19-AA. Rev 2.2 Oct. 2008, © 2008 all rights reserved. Page 1 1 SYSTEM DESCRIPTION 1.1 INTRODUCTION The TDD Mini repeater system is designed to improve coverage for customers using TDD broadband 2500-2700 Mhz in medium size indoor areas. The system implements BDA technology to enhance coverage in urban areas. Repeaters are used to fill out uncovered areas in cellular mobile systems, such as base station fringe areas, road tunnels, business and industrial buildings, etc. A repeater receives signals from a base station, amplifies the signals and retransmits them to mobile stations. It also receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously. To be able to receive and transmit signals in both directions, the repeater is connected to a donor antenna directed towards the base station, and to a service antenna directed towards the area to be covered. The repeaters are controlled through the Cellvine Operation Software Terminal, installed on desktop or laptop computers, which enables communication with the repeaters either locally using a communication cable, or remotely via a modem (optional)*. Local communication can be also performed via a Bluetooth device (optional), which allows the user to control and monitor the repeater through the operation software over a distance of up to ~200 feet between the repeater and the monitor PC/laptop, eliminating the need for using a communication cable. *In the future (depending on IP-Wireless network evolution and equipment testing), Cellvine will offer a Network Management System - NMS, which will allow multiple repeaters in a single network to be controlled from a central console, offering improved efficiency and responsiveness from enhanced cellular network coverage. The Cellvine NMS can be installed as a full application on a specific workstation at the client’s network operations center (NOC) as SNMP packets, or implemented as a fully IP-based Web Interface over the Internet. Cellvine’s NMS GUI enables technicians to tune repeater parameters during installation and during further optimization stages. Alerts can also be sent out via email, over the Internet or as SNMP packets, which can be picked up by the NMS and displayed on the NOC PC or any other browser-enabled device.

The donor antenna receives cellular signals (assuming sufficient coverage exists outside the building or near a window). The BDA amplifies the signals transmitted by the coverage antennas in the coverage areas. The mobile handset signals are received by the coverage antennas, amplified by the BDA, and transmitted through the donor antenna back to the cellular base station site. This enables cellular signals to be re-transmitted in some locations, in order to extend cellular coverage.

Page 9 1.10.1 Donor Panel Antenna Cellvine provides a unique, slim and well-designed donor antenna in the repeater kit, instead of a regular Yagi antenna. This antenna is designed to provide attractive appearance and smaller dimension when installed in private homes or public places. The solution is based on a panel antenna with a narrow beam pattern of 24º. The advantages of this antenna are being aesthetically more appealing, lightweight, relatively small dimensions, and simple installation. Although this is a panel antenna, it performs much better than other panel antennas with similar dimensions, especially in the pattern beam width (see Figure 5). The antenna gain is 9 dBi. The antenna is designed to be mounted on a glass window, using a window bracket that is attached to the window with two-sided adhesive tape. For the adhesive tape specifications, please see Adhesive tape specifications, page 13. Figure 3: Donor panel antenna dimension in inches

Page 12 1.11 DONOR SIGNAL STRENGTH MEASUREMENT TOOL The donor panel antenna includes a signal level meter indicator (Figure 6) for measuring the RSSI signal level from the donor BTS in the neighboring area. The measurement tool receives a signal from the repeater controller through the coax cable connected to the donor antenna. It measures the signal output level of the repeater output according to the signal received at the donor antenna from the BTS. This will help installing the donor antenna in the optimal direction and at the optimal angle, in order to achieve the highest RSSI level signal from the BTS. For operation instructions, please refer to Tuning Donor Antenna via Signal Level Indicator, page 24. Figure 6 : Donor signal level measurement tool

At room temperature approximately 50% of ultimate bond strength will be achieved after 20 minutes, 90% after 24 hours and 100% after 72 hours. This flow is faster at higher temperatures and slower at lower temperatures. Ultimate bond strength can be achieved more quickly (and in some cases bond strength can be increased) by exposure of the bond to elevated temperatures (e.g. 150°F [66°C] for 1 hour). This can provide better adhesive without on to the substrates. Abrasion of the surfaces or the use of primers/ adhesion promoters can also have the effect of increasing bond strength and achieving ultimate bond strength more quickly.
Installation Unpacking and Inspection TDD Mini Repeater: BDA-TDD-25-16-19-AA. Rev 2.2 Oct. 2008, © 2008 all rights reserved. Page 14 2 INSTALLATION This section provides information about the installation and setup of the Cellvine repeaters. The information consists of procedures for unpacking, inspection and preparation for the installation, as well as the actual installation and setup. It is important to install the repeater correctly at its working location. It is recommended that installation be performed by a certified radio technician. The repeater installation consists of four basic steps: 5. Antenna installation 6. repeater installation 7. Cable installation 8. Repeater parameters setup and tuning with the control application. 2.1 UNPACKING AND INSPECTION 1. Examine the shipping package for damage before unpacking the unit. If the shipping package is damaged, try to unpack the equipment in the presence of the carrier’s agent. If visual inspection reveals physical damage to the equipment, you should send it back for replacement. 2. Verify that the equipment includes all components, as listed in the packing slip. If components are missing, contact Cellvine Ltd. 2.2 ANTENNA INSTALLATION Coverage (mobile) antenna – facing to the "no coverage" area. The most commonly used antennas for indoor applications are Omni or panel antennas. When multiple indoor areas should be covered, more than one antenna can be used. Indoor antennas are usually placed near the ceiling with decorative covers. Decisions as to where to locate the antenna take into account isolation issues, and the need to overcome interfering signals. For outdoor coverage, panel antennas are commonly used. The location of the antenna is determined by coverage and isolation matter. Base (donor) antenna – installed behind a window glass, facing the donor BTS. The choice of donor cell site should take into consideration capacity, range and signal level in the outdoor antenna location. The location should be chosen so, that donor cell site reception will be at a higher level than all other adjacent cell sites. For this purpose, the outdoor antenna should have high directivity and high Gain. If possible, this antenna should directly face the nearest cellular site with a line-of-sight view. For further installation instructions, please refer to paragraph Donor Antenna Installation, page 15. Isolation issue – to assure proper repeater operation, the isolation between the indoor (Mobile) and outdoor (Base) antennas should be at least 15 dB higher than the repeater's maximal gain. This isolation parameter can be measured simply by transmitting a continuous, CW unmodulated pilot signal of 0 dBm at the repeater Base port (donor antenna), and measuring the received signal at the repeater Mobile port (service antenna port).
Installation Pre-Installation Inspection TDD Mini Repeater: BDA-TDD-25-16-19-AA, Rev 2.2 Oct. 2008 © 2008 all rights reserved. Page 15  Note: the isolation parameter should be measured between the coax cables that are connected to the Base and Mobile ports, without the repeater. For example, if the measured isolation parameter between the Base and Mobile ports is 90 dB, the maximal repeater gain should not exceed 75 dB. 2.3 PRE-INSTALLATION INSPECTION Before beginning the repeater installation, determine the following:  Base station location and receiving power (TX power in dBm)  Location where the Base/Mobile antenna is to be installed  Location where the repeater is to be installed  Length of coaxial cable needed to connect from the Donor antenna to the repeater unit  Length of coaxial cable needed to connect from the repeater unit to the indoor antenna/s.  Isolation estimation between the donor and the coverage antenna/s. 2.4 DONOR ANTENNA INSTALLATION The panel donor antenna can be installed either attached to a window glass, using the front window mounting bracket, or on a wall or flat surface using the rear wall mounting bracket. 2.5 ANTENNA WINDOW INSTALLATION To install the antenna attached to a window glass, perform the following steps: 1. Locate all the antenna’s front bracket parts, as shown in Figure 7. 2. Attach the antenna holder to the antenna adaptor installed on the front of the antenna, as shown in Figure 8. 3. Glue the antenna holder to the most suitable spot on the window. Before gluing, clean and remove fat and dust from the gluing area. Note that the adapter should be glued onto the window vertically. The adapter must be glued pointing up, see Figure 8 and Figure 9. 4. Press the antenna and front bracket gently onto the window, and wait a few seconds to ensure that it is properly attached, as shown in Figure 9.  RF exposure warning! In order to comply with FCC RF exposure regulations, you must ensure that the donor antenna is installed at a minimum distance of 0.2 m (7.8 inches) from persons who may be present in the area.

Repeater Communication, Monitoring and Control Repeater AGC ON - Operation Mode TDD Mini Repeater: BDA-TDD-25-16-19-AA, Rev 2.2 Oct. 2008 © 2008 all rights reserved. Page 26 3.3 REPEATER AGC ON - OPERATION MODE By default, when setting the AGC switch to ON, the repeater should work in fully automatic mode. In this mode, the Gain of the repeater will be set automatically to ensure that the output power is equal to the maximal linear power of the repeater. In instances where the signals exceed the linear level, an automatic attenuator will reduce the Gain. If the signal in the input of the repeater increases, the repeater will reduce the Gain in order to achieve the AGC parameter value that was set. If the input signals from the BTS decrease after a while, the Gain of the repeater will increase again, by 1 dB.  Note: the AGC ON mode can be set either manually from the side panel, or by using the control Software 3.4 AGC OFF-OPERATION MODE In AGC OFF mode, the AGC mechanism is no longer in control of the increase or decrease of the repeater Gain. The Gain level in AGC OFF operation mode is fixed, and will not be changed automatically by the repeater. In light of this, it is important to measure and control the input level of the signal coming from the BTS. Example: in AGC OFF mode, the Gain is fixed at 80 dB. The maximum output level allowed from the unit is 16 dBm, and the maximum input signal level from the BTS is therefore 16-80 = - 64 dBm. This means that if the input signal from the BTS is higher, e.g., -55 dBm, and the fixed Gain is 80 dB, the output level will be -55+80= +25 dBm. This repeater model is designed for a maximum of + 16 dBm output power, and +25 dBm output power levels will damage the unit. You can configure the output power in AGC OFF mode and set the repeater Gain manually, by using the two rotation knobs on the front panel. In AGC OFF mode, the knobs on the front panel are used as attenuators in order to reduce the maximum Gain of the repeater (80 dB), by up to 23 dB (in the range of 80-57 dB).

Alarms and Protection Mechanisms Low Signal Alarm TDD Mini Repeater: BDA-TDD-25-16-19-AA. Rev 2.2 Oct. 2008, © 2008 all rights reserved. Page 42 6 ALARMS AND PROTECTION MECHANISMS Cellvine TDD Mini repeater is equipped with several alarms and smart protection mechanisms that provide alerts, and protect the repeater and the cellular network. This section describes the default alarms and protection mechanisms. The alarms are indicated in two ways: 1. LED indication on the side panel of the repeater. For detailed description of LEDs alarm indications please see Alarm LEDs indications, page 45. 2. On the Cellvine application screen, in the Alarms Current Value column of the Technician Setup screen. 6.1 LOW SIGNAL ALARM The Low Signal Alarm indicates that the incoming signal on the Forward path (from the BTS) is low, and the repeater is not performing at maximum efficiency. The alarm is triggered when the value of the forward power is 3 dBm lower than the AGC power parameter setup. Example: The AGC power is set to 16 dBm and the Forward Power readout in the "Measured Power" parameter screens, is less the 13 dBm. A "Low Signal" alarm notification appears in the application window. Figure 33: Low Signal alarm
Alarms and Protection Mechanisms Over-power alarm - High Signal Protection TDD Mini Repeater: BDA-TDD-25-16-19-AA, Rev 2.2 Oct. 2008 © 2008 all rights reserved. Page 43 6.2 OVER-POWER ALARM - HIGH SIGNAL PROTECTION The Overpower mechanism and alarm protects the repeater from unexpected burst of high RF signal, avoiding damage to the repeater and the cellular network. The alarm is triggered when a high signal is detected at the input of the repeater. An automatic Gain attenuation will reduce the Gain with up to 30 dB. If after the maximum Gain reduction is applied, the output power of the repeater is at least 1 dB higher than the "AGC Power" parameter, an "Over Power" alarm notification appears in the application window. Figure 34: Overpower alarm
