Preliminary Document Confidential EMS Wireless Link2CellTM-19 Manual 8 Link2Cell™-19 Manual Description The Link2Cell™-19 SOHO, (Small Office-Home Office) Signal Enhancer, is a PCS band, bi-directional amplifier unit and was designed to provide enhanced RF coverage for wireless systems in small facilities. Usage includes providing coverage in retail stores, offices, warehouses, restaurants, homes, etc. The Link2Cell™-19 is housed in an indoor mountable enclosure, and is powered with a regulated wall mountable power supply. The Link2Cell™-19 supports all system protocols including CDMA, GSM/PCS1900 and TDMA and a single model will cover all licensed 1.9 GHz PCS bands A through F. The Link2Cell™-19 features Auto set-up, lightweight compact enclosure with internal antennas, local alarming, and excellent electrical specifications, high reliability with cost effective pricing. Functionality The Link2Cell™-19 is capable of automatically adjusting its own signal gain levels up to the maximum output power levels. The Link2Cell™-19 detects the downlink output power and adjusts the level for 2 dBm composite output power and continues to monitor and reset the gain as required for proper system performance. For example, when CDMA protocol system is being amplified, there could be an error in set up initially resulting from only pilot sync, and paging Walsh codes being present on the RF carrier. The Link2Cell™-19 will reduce the system gain until no signal is received that will exceed the output power setting. This prevents the Link2Cell™-19 from setting up to a higher in power level than actually desired if all of the Walsh codes were present. The gain does not continually change to maintain an output power of 2 dBm AGC (Automatic Gain Control) since this would defeat the benefits of power control in the service providers system. The Link2Cell™ has 40 dB of gain control in the uplink and downlink signal paths. This gain is controlled by a microprocessor that monitors the system operation on a real time basis. The uplink and downlink attenuators are controlled by the internal microprocessor to adjust for maximum gain in both paths. The uplink and dowlink signal paths are adjusted to the same setting by the microprocessor unless the system determines this is not optimum for the units operation. Alarming Alarming monitoring is accomplished in the Link2Cell™ by the microprocessor, which will detect a failure in gain or a system oscillation. This is indicated to the user by a solid constant

User can try recycling the power which will allow the unit to go thru its automatic set up operation but if the problem persists contact your service provider. Indicators The Link2Cell™-19 is equipped with three LED indicators on the end of the unit which provide the following information: During normal operation: Indicator State Description Green Off No DC Input Power Applied Solid Indication DC Power on, normal function Flashing Indication System Initialization, Auto Set Up Red Flashing Indication Warning, fault condition (Unit will reset gain to stable operation) Solid Indication Alarm (Contact your Service Provider) Amber Flashing Indication No RF Signal Detected (<-90 dBm) Solid Indication Weak RF Signal (>-85 dBm) Initial System Automatic Set Up: (First 2-3 minutes of DC power being applied) Indicator State Description Green Flashing Indicator System Initialization, Auto Set Up Amber/Red Solid On, Both >76 dB Gain Amber Solid On Indication >73 dB Gain Red Solid On Indication >70 dB Gain Amber/Red Flashing Both >67 dB Gain Amber/Red Off, both <64 dB Gain *Green Indicator will go to a solid indication once the initial set up is complete.
Preliminary Document Confidential EMS Wireless Link2CellTM-19 Manual 10 Primary Power The Link2Cell™ Unit operates on 9 VDC input power @ 1 Amp. This is supplied with a regulated wall mount supply, which is UL, and CSA listed. These are available to operate on AC input voltage of 115 VAC. Donor/Server Antenna Internal donor and server antenna are each 13 dB nominal gain. The donor antenna must be orientated to point in the direction of the Service Providers cell site location. Beam width of the antennas is approximately 60 degrees wide so it is necessary for the antenna to point toward the cell site. The indicators will provide a reference of the strongest RF power strength when the antenna is located in the optimum location.
Preliminary Document Confidential EMS Wireless Link2CellTM-19 Manual 11Installation: Note 1: The user is cautioned that modification or changes to this device not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. Note 2: Manufacturer’s rated composite output power, individual channel power will vary depending on the number of channels and distance from each cell site being received Note 3: This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. Introduction Link2Cell™-19 is quick and easy to install, using a set of common tools. This section will provide the basic steps to performing the installation of Link2Cell™ . Please read complete instructions before beginning assembly. Placement of the Unit Unit must be positioned with the donor antenna facing the direction of the cell site and the opposite side of the unit with LED indicators facing the intended coverage area. Signal strength at this location should be adequate to make a call with the subscriber unit for the SOHO, (Small Office-Home Office) signal enhancer to provide additional coverage and service in the facility. (See optional mounting configurations in figure 2.) The signal enhancer provides improved signal performance by amplifying radio frequency signals being received from the base station and the subscriber unit (mobile phone). The model Link2Cell™ provides signal enhancement for the entire PCS band only, see the Link2Cell specifications for details on equipment. Link2Cell™ is designed to automatically set up its own gain and will improve performance in most applications as long as a signal is received at the window location. Actual area of coverage that will be improved will vary depending on the signal level received, and blockage to the signals in the desired area of coverage. Blockages to RF signals include walls, people, equipment and furniture, etc. Amount of signal attenuation by each of these blockages will vary depending upon their size and composition. If additional area of coverage is required, additional Link2Cell™ units can be cascaded inside of the facility to provide this. There is a practical limit to the number of signal enhancers that can be cascaded and provide enhanced system performance. If greater than three total Link2Cell units are required you should call your system provider for additional solutions that are available.

Preliminary Document Confidential EMS Wireless Link2CellTM-19 Manual 13 Link2Cell™-19 Unit Orientation & Installation Link2Cell™ is designed for optimum use as an in-door signal enhancer. The housing is not weather resistant and the automatic set up procedure assumes sufficient isolation between antennas. Since the Link2Cell™ has a total of 53 dB active gain and an isolation of 73 dB must be obtained between the internal donor and the server antenna. Should adequate isolation not be obtained the unit will automatically reduce its gain until adequate isolation is obtained for the unit to operate properly. Isolation between the antennas is reduced by several conditions near or around the antennas, metal or conductive material, and movement of people near the antennas. Mounting the Link2Cell™-19 Link2Cell™-19 must be mounted so the Donor antenna is orientated to receive and transmit to the cell site. The Donor antenna is located on the opposite side of the unit of the LED indicators of the Link2Cell™-19 with the LED’s either at the bottom or the top to keep the orientation of the Donor antenna correct with respect to the direction of the cell site and which wall you desire to mount the unit on. 9 VDC input is located on the side of the Link2Cell™-19 housing shown above. The Link2Cell™-19 may also sit on top of a book case, cabinet or on the floor as long as adequate signal is received by the unit to provide the desired coverage enhancement. As was previously discussed, these cabinets and bookcases should not be metal since this will effect the performance of the unit. OR OR .
