1-2 About LGCell
1-3What LGCell IsLGCell is a “plug-and-play” in-building distributed antenna system (DAS) that enables highly reliable, high-quality wireless communications.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.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)Double-Star Topology for Easy, Cost-Effective GrowthThe LGCell system uses a double-star topology, which allows for easy, cost-effective 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 CoverageOutdoor 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 Multi-Mode Fiber (MMF)Roof-001LGCellExistingOutdoorBase StationMountedAntennaCategory 5 UTP/STPIn-BuildingAntennaRepeater
1-4 About LGCellcommunications when a user is within range of an LGCell Remote Antenna Unit (RAU).LGCell Increases In-Building CoverageLGCell 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.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 LGCellsUse multiple LGCell systems to increase coverage in very tall buildings or large facilities.•Increase Coverage for Separate Service ProvidersUse one or more LGCell systems for cellular networks and use one or more for PCS networks.•Increase Coverage for Separate NetworksUse one or more LGCell system for public networks and use one or more for private networks.Expanding Inside – Increases In-Building Capacity and CapabilityIncreased 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.b002Roof-Mounted AntennaRepeaterWiringClosetMHEHRAU
1-5Microcellular Base Station (MBS) for Increased CapacityConnecting the LGCell to a local, centralized MBS provides additional capacity, as well as enhanced coverage.This in-building microcellular wireless network increases the number of in-building users able to communicate through their wireless phones.• LGCell provides coverage• MBS provides voice channel capacity• 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 centralizedThe 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 CapacityLGC 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.Specific installation information on all available Integration Modules is in the Integration Module Installation and Reference Manual. LGCell, MBS, PBX* for Increased Coverage, Capacity, and FunctionalityInterfacing 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.a010MBS MHEHEHEHEHRAU

1-9The 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 buildingDual Band Expansion HubAn 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
1-10 About LGCellDual Band RAUThe RAU for a Dual Band LGCell system is a pair of RAUs, one for each band.How LGCell WorksLGCell 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 OperationSystem 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.
1-11Transmit/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 AdvantagesThe 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.
