This one-person-one-phone capability gives a wireless phone user the ability to use their wireless phone in any location throughout the enterprise and beyond. Existing Outdoor Base Station Repeater RoofMounted Antenna In-Building Antenna LGCell Seamless coverage lets wireless phone users roam freely between buildings as well as indoors and outdoors without changing phones. An LGCell system has the following equipment: Main Hub (MH) • Expansion Hub (EH) • Remote Antenna Unit (RAU) Category 5 UTP/STP Multi-Mode Fiber (MMF) 001 • Double-Star Topology for Easy, Cost-Effective Growth The LGCell system uses a double-star topology, which allows for easy, costeffective growth of coverage and/or capacity. Each Main Hub supports up to four Expansion Hubs. Each Expansion Hub, in turn, supports up to four RAUs. The Main Hub is located in an equipment closet and the Expansion Hubs are distributed out into other equipment closets throughout a building. The RAUs are then distributed off each Expansion Hub to provide coverage. Bringing Outside In – Increases Wireless Network Coverage Outdoor macrocellular base stations (BTSs) transmit and receive Radio Frequency (RF) signals, which enable communications with wireless phones. The RF signals are not always available or adequate inside a building, campus, tunnel, subway, or other hard-to-reach location. The LGCell system delivers high-quality wireless 1-3 communications when a user is within range of an LGCell Remote Antenna Unit (RAU). LGCell Increases In-Building Coverage LGCell operates in the cellular or PCS frequency bands and can act as an extension to the cellular or PCS network. LGCell extends RF signal coverage in places where the coverage is unacceptable. This extended coverage allows users to roam between buildings and the outside world while maintaining wireless phone conversations without changing phones. Roof-Mounted Antenna Repeater Wiring Closet MH EH RAU b002 LGCell provides coverage for a variety of applications including single and multiple floor buildings, campus environments, tunnels, subways, and public facilities. LGCell can be connected to a separate repeater for a power boost or when line of sight is poor. • Increase In-Building Coverage with Multiple LGCells Use multiple LGCell systems to increase coverage in very tall buildings or large facilities. • Increase Coverage for Separate Service Providers Use one or more LGCell systems for cellular networks and use one or more for PCS networks. • Increase Coverage for Separate Networks Use one or more LGCell system for public networks and use one or more for private networks. Expanding Inside – Increases In-Building Capacity and Capability Increased in-building wireless coverage from the outdoor wireless networks does not always fully address in-building needs. Coverage is only beneficial if all potential users can access the network. 1-4 About LGCell Microcellular Base Station (MBS) for Increased Capacity Connecting the LGCell to a local, centralized MBS provides additional capacity, as well as enhanced coverage. • • • • • • • EH MBS MH LGCell provides coverage MBS provides voice channel capacity RAU Protocol independent Calls can be charged at a flat rate versus cellular or PCS rate inside the building Provides completely uniform radio coverage at low cost MBS capacity is dynamically allocated as needed Maintenance and control of the wireless network are centralized EH EH EH a010 This in-building microcellular wireless network increases the number of inbuilding users able to communicate through their wireless phones. The LGCell/MBS connection allocates capacity to various locations within the enterprise as user traffic patterns change over the course of a day. Integration Modules for Dynamic Allocation of Radio Capacity LGC Wireless provides Integration Modules that can be used with the LGCell to efficiently centralize additional radio capacity inside a facility. These Modules provide the connection between the radios for the facility and the LGCell system. Because the Integration Modules distribute all available capacity automatically throughout all antennas within a cell, available capacity is dynamically allocated throughout the entire coverage area, thus providing an improved grade of service without the need to conduct ongoing traffic monitoring and analysis.

LGCell, MBS, PBX* for Increased Coverage, Capacity, and Functionality Interfacing the LGCell with an MBS/PBX network gives wireless phone users PBX functionality through their wireless phones, anytime, anywhere. *Check with PBX manufacturer/vendor for compatibility, connection, and operation. 1-5 EH MBS MH RAU EH EH EH a011 PBX With the LGCell/MBS/PBX solution, employees can use a wireless phone in place of a wireline desk phone to access the PBX while inside the building and use the same phone for wireless communications while outside the building. The MBS private wireless network transmits RF signals indoors, and the macrocellular network takes over outdoors. • • • Access PBX features such as four-digit dialing, call delivery, call forwarding, call-waiting, conferencing, and voice mail Billed at discounted local calling rates or a flat enterprise rate for calls made inside the LGCell vicinity Users can maintain the same telephone number inside and outside of the building, enabling anytime, anywhere communication LGCell Equipment One fully equipped LGCell system consists of the following parts: • One Main Hub • Up to four Expansion Hubs • Up to 16 RAUs (four per Expansion Hub) Multiple LGCell systems can be stacked for various applications. (See Section 5, Connectivity.) A Dual Band LGCell system has two Main Hubs and at least two Expansion Hubs. A Dual Band system is a combination of single bands. The following illustration shows a Dual Band 900/1800 LGCell system. 1-6 About LGCell Dual Band LGCell System The following sections provide a brief overview of LGCell equipment. For a detailed description of the equipment, see Section 2, LGCell Equipment. The Main Hub 1-7 The Main Hub mounts into a standard 19" equipment rack commonly found in wiring closets or equipment rooms (Main Hub width is 17.25”, or 438 mm). • Interfaces to the wireless network • Height is 1.7" (44.5 mm) • Connects to a roof-mounted antenna, repeater, or MBS via standard coaxial cable or low-loss coaxial cable with N-type male connectors Dual Band Main Hub The Main Hub for a Dual Band LGCell system is a pair of Main Hubs, one for each band. The Expansion Hub 1-8 About LGCell The Expansion Hub also mounts into a standard 19" equipment rack (width 17.25”, or 438 mm). • Height is 1.7" (44.5 mm) • Connects to the Main Hub via standard Multi-Mode Fiber (MMF) cable (up to 1.5 dB optical loss, approximately 1 kilometer without jumpers). • Hubs can be located in wiring closets anywhere in the building Dual Band Expansion Hub An Expansion Hub for a Dual Band LGCell system is a pair of Expansion Hubs, one for each band. The Remote Antenna Unit (RAU) The RAUs a re strategically positioned in and around a building to provide high-quality reception for wireless services. • Connects to the Expansion Hubs via standard CAT 5 (or better) unshielded or shielded twisted pair (UTP/STP) cable (up to 60 meters) (TIA/EIA 568-A standard) • Mounts onto a variety of building materials. Can be placed anywhere – above or below the ceiling, on the wall, or in other locations. • Connects to any external antenna, dipole, directional, omnidirectional, panel, or other antenna 1-9 Dual Band RAU The RAU for a Dual Band LGCell system is a pair of RAUs, one for each band. How LGCell Works LGCell connects in an Ethernet, LAN-like architecture, using a double-star topology. It uses proprietary technology to provide wireless access within buildings, subways, tunnels and other locations where reception is poor. System Operation System operation for all of the LGCell DAS products is identical. The only differences between the products are the operating frequency range, access scheme (TDMA, GSM, etc.) and certain operating parameters (gain, etc.). The Main Hub connects to an RF source: • a roof-mounted antenna or repeater for coverage applications; or • an MBS for capacity or wireless PBX applications, or both. LGCell distributes cellular and PCS signals through standard MMF and standard UTP/STP cable found in most buildings. This allows installation of in-building wireless services with minimal installation time and cost. 1-10 About LGCell Transmit/Forward/Downlink (BTS to Phone) The incoming RF signal into the Main Hub is split into several fiber optic transceivers that convert the RF signal to an optical signal. The Main Hub transmits the converted signal over the fiber to the Expansion Hub. The Expansion Hub converts the optical signal to an RF signal and transmits the RF signals to the RAUs. The RAUs then transmit the RF signals to the antenna and then to wireless phones. Receive/Reverse/Uplink (Phone to BTS) The RAUs transmit RF signals from wireless phones back through the antenna and to the Expansion Hubs. The Expansion Hubs transmit the RF signals back to the Main Hub in optical form. The Main hub converts the optical signals back to electrical signals and sends them to an MBS, a repeater, or a roof-mounted antenna. For a detailed description of system operation, see Section 2, LGCell Equipment. LGCell Advantages The LGCell solution is based on a fundamentally new approach that has cost and engineering advantages not found in competitive systems. Competitive systems offer similar capabilities but require sophisticated RF engineering and take a long time to install. They typically use specialty cables that require expensive, difficult, time-consuming, and potentially disruptive installations. LGCell’s plug-and-play design requires minimal RF engineering and planning. Its unique double-star architecture keeps service and maintenance to a minimum, unlike cascaded antenna systems. The flexible architecture permits deployment in the most difficult RF environments. LGCell’s low cost and simple installation effectively provide both coverage and capacity enhancements to meet the demands of the growing wireless network. 1-11 LGCell Uses Industry Standards LGCell’s use of industry standards and standard equipment offers high reliability and low cost. • Complies with industry standards for IS-19-B/AMPS, J-std-8, IS-136/TDMA, IS-95/CDMA, ETSI 300 609-4/GSM (CE marked), and iDEN. • Utilizes the TIA/EIA 568-A Ethernet cabling standards for ease of installation (see Appendix A – Cables, Connectors, and Accessories). • Distributes signals over a building’s existing industry-standard cable infrastructure of MMF and UTP/STP cable. • Complies with UL and FCC or CE mark requirements. • Primarily constructed with highly reliable industry-standard components produced in high-volume for the LAN and wireless industries. High quality and reliability are assured. Minimal Design, Installation, Maintenance, and Troubleshooting • Site engineering is simplified since compensation for cable loss and amplifiers do not need to be designed into the system, which saves precious RF Engineering time and support. • Using standard cabling reduces installation to simple equipment mounting and cable connection. • Centralized hub locations facilitate maintenance, upgrades, and adaptability to new standards. • The LGCell’s star configuration eases troubleshooting – it is immediately clear if an RAU is faulty. • LGCell provides full Operations Alarm Maintenance and Provisioning (OAM&P). The Main Hub senses major alarms through contact closure. These alarms can be sent to remote locations. (For information on the Alarm Report Monitor, see Appendix E – Alarm Report Monitor (ARM2000).)

The LGCell 1800/ 1900 MHZ system has a fixed bandwidth filter in each system that is centered over the desired band of operation. The desired band of operation is an ordered item either by band (A, B, D, E, F) or by the center uplink and downlink frequency. 2-20 LGCell Equipment The following table shows the bandwidths for each type of system. System DAS 800 MHz - AMPS, Fixed Filter Bandwidth Uplink Center Frequency Downlink Center Frequency 25 MHz 836.5 MHz 881.5 MHz DAS 800 MHz - iDEN 18 MHz 815 MHz 860 MHz DAS 900 GSM 25 MHz 947.5 MHz 902.5 MHz DAS 1800 KOREAN CDMA 30 Mhz 1765 MHz 1855 MHz DAS 1800 DCS (GSM) 30 MHz 1725 MHz1 to 1770 MHz 1820 MHz1 to 1865 MHz DAS 1900 MHz - CDMA, 15 MHz 1857.5 MHz2 to 1892.5 MHz 1937.5 MHz2 to 1972.5 MHz TDMA, CDMA TDMA, GSM For example, the A band for 1900 MHz PCS has the fixed 15 MHz filter centered at 1937.5 MHz for the downlink and 1857.5 for the uplink. 30 MHz pass filter can be positioned along the 75 MHz DCS 1800 band. Order product with uplink and downlink frequency at 1.25 MHz spacing. For example an uplink center frequency of 1737.5 MHz will provide a 30 MHz band between 1722.5 MHz and 1752.5 MHz and a downlink center frequency of 1832.5 MHz will provide a 30 MHz band between 1817.5 MHz and 1847.5 MHz. Similar to above, the 1900 PCS 15 MHz filter can be positioned along the 60 MHz band. The LGCell covers a 30 MHz band in frequency range of 1710 MHz to 1785 MHz on the uplink and 1805 MHz to 1880 MHz on the downlink. The operator can choose where to place the 30 MHz band of operation by choosing the corresponding center frequencies as shown in the following table. 2-21 Band Center Frequency of the DCS 1800 MHz LGCell The filter band is 30 MHz wide (or 15 MHz on each side of the center).

Proper project management is instrumental in providing a timely and accurate deployment. The first step in planning an LGCell system is to estimate the amount of radio frequency (RF) coverage you need for your building or coverage area. Initial estimates can be developed using floor plans and the models that follow. Eventually you need to go on-site to evaluate the facility’s readiness for installation and possibly perform RF measurements in order to guarantee performance. The LGC Wireless Site Survey Questionnaire is included for your reference.

It is beneficial to have one person manage and coordinate all aspects of the planning, design, and installation. Managing the process should avoid unnecessary surprises. The project manager is the person responsible for assigning tasks and ensuring scheduled work is performed on time. This includes collecting all information necessary for a complete site assessment, getting cost estimates and purchase order (PO) approval, scheduling any cabling work, scheduling the LGCell installation and commissioning, and providing final as-built documentation. The project manager also acts as the coordinator between the following people: Cellular or PCS carrier RF engineer Site acquisition person MBS vendor MBS installer Cabling contractor(s) End user If you do not have a designated project manager, please contact LGC Wireless. We can provide you with an estimate of what it would cost to have LGC Wireless manage your project. Please call us at 1-800-530-9960 (in the U.S.). International customers, please call us at +1-408-487-2400. 3-3 Project Management Estimated Timeline Description Details Time Interval Detailed site walkthrough/RF survey Prepare installation information, including RF plan, floor plan, equipment order form, and final design. 2 weeks Order LGCell equipment Get all standard parts and accessories required. 8 weeks Select cabling contractor Complete installation statement of work and provide floor plan with equipment locations, list of cabling runs, and other materials and connections.

As a guideline, you can refer to the following tables for general coverage areas, based on a design goal of 0 dBm output power per carrier, -85 dBm received signal strength (independent of communications protocol), 5 dB fade margin and 3 dBi antenna gain. 3-4 LGCell Site Planning and Design Antenna Coverage for 800/900 MHz Frequency Applications (0 dBm per carrier, 5 dB fade margin, -85 dBm design goal and 3 dBi antenna gain) Facility PLS Coverage per Antenna (Square Feet) Manufacturing 27.3 30,000 Hospital 28.8 15,000 Airport 27.3 30,000 Retail 27.7 25,000 Warehouse 27.3 30,000 Parking Garage 26.8 40,000 Antenna Coverage for 1800/1900 MHz Frequency Applications Facility PLS Coverage per Antenna (Square Feet) Manufacturing 24.9 25,000 Hospital 26.5 10,000 Airport 24.9 25,000 Retail 25.2 20,000 Warehouse 24.9 25,000 Parking Garage 24.3 35,000 Office Antenna Coverage for 800/900 MHz Frequency Applications Facility PLS Coverage per Antenna (Square Feet) Open - 80% cubicles/20% offices 27.7 25,000 80% - 50% cubicles/50% offices 28.2 20,000 10% - 20% cubicles/80% offices 28.8 15,000 3-5 Office Antenna Coverage for 1800/1900 MHz Frequency Applications Facility PLS Coverage per Antenna (Square Feet) Open - 80% cubicles/20% offices 25.2 20,000 80% - 50% cubicles/50% offices 25.7 15,000 10% - 20% cubicles/80% offices 26.5 10,000 The preceding tables show estimated clutter-defined path loss slope (PLS) for different frequencies at various kinds of sites. If you change the design goal or other parameters, these numbers will change based on the PLS. If the design parameters (output power per carrier, design goal, antenna gain, and fade margin) differ from those stated above, you can use the PLS value shown in the preceding tables in the following formula to estimate the area of coverage per antenna: Path Loss Formulas Path Loss (dB) = PLS * log 4πfD / c Note: Path Loss Slope = PLS dB/decade for free space loss D is the distance in meters f is the frequency in MHz c is the speed of light Path Loss=Power per Carrier + Antenna Gain - Fade Margin - Design Goal (dBm) D = [10(Path Loss / PLS)] x [c / (4πf)] To convert feet to meters: Area = (D x 3.281)2 x π The PLS is a general path loss number which takes into account free space loss and normal barriers to the RF signal. Severe obstructions such as metal, cement walls, or elevator shafts are best accounted for by a physical site survey. 3-6 LGCell Site Planning and Design As a reference the following table gives estimates of the signal loss for some RF barriers. Average Signal Loss of Common Building Materials Partition Type Loss @ 815 MHz Metal wall 26 dB Aluminum siding 20 dB Concrete block wall 13 dB Foil insulation 4 dB Concrete floor 15 dB Sheetrock 1.4 dB RF Measurements and Site Survey Before designing an LGCell system, one should go to the site and measure the loss characteristics of the building. To determine the amount of coverage per antenna, the best method is a test of RF propagation, which you can do on-site with a test transmitter and field strength meter. While at the site, one can use the following Site Survey Questionnaire to document site specifics. Site Survey Questionnaire You can use the LGC Wireless Site Survey Questionnaire to help design your LGCell system. A sample questionnaire follows.
