ESystem Operation2.2 System OperationDownlink (Base Station/Repeater to Wireless Handsets)• The LGCell system’s Main Hub is usually installed in a 19 in. (483 mm) equip-ment rack in a wiring closet or equipment room inside the facility where coverage will be provided. Coaxial cable is used to connect the Main Hub to a local base sta-tion or to a repeater that is attached to a roof-top antenna. The Main Hub receives the incoming RF signals and splits them to feed four internal fiber optic transceiv-ers that convert the RF signals to optical signals. The Main Hub transmits the opti-cal signals over multimode fiber to up to four Expansion Hubs, which are usually installed in other telecom closets throughout the facility.WARNING: Exceeding the maximum input power could cause failure of the Main Hub (refer to Section 7.1 on page 7-3 for maximum power ratings). Attenuators may be required to limit the maximum composite power into the Main Hub.•The Expansion Hub converts the optical signals back to electrical signals, which are then transmitted to up to four Remote Access Units (RAUs) over Cat-5 UTP/STP cabling.•The Remote Access Unit receives the electrical signals from the Expansion Hub and transports the signals over a short coaxial cable to an attached passive antenna, which then transmits the RF signals to wireless handsets.Uplink (Wireless Handsets to Base Station)• The passive antenna relays the RF signals from wireless handsets to the Remote Access Unit, which then transmits the signals to the Expansion Hub over Cat-5 UTP/STP cabling.•The Expansion Hub converts the electrical signals to optical signals and transmits the signals to the Main Hub over MMF.•The Main Hub converts the optical signals to the proper frequency band RF sig-nals and sends them to a local base station or to a repeater that is connected to a roof-top antenna.

E2.2.3 Using LGCell to Simultaneously Support Multiple Bands/ProtocolsThe LGCell can simultaneously support more than one frequency band. Two options include:• The Dual Band LGCell for an Operator running parallel networks in the same mar-ket• The neutral host configuration, which is described hereThe term “neutral host” refers to the fact that the system supports multiple wireless Operators and that the equipment typically is owned by a third-party company.Neutral host systems are deployed in situations such as the following:• Public microcellular applications such as airport terminals, subways/train stations, and similar public buildings usually require that the in-building RF distribution system infrastructure be capable of supporting any current frequency band and protocol, including paging and messaging, and that it be future-proof.• It is common for the same service provider to be licensed to operate in multiple bands in the same geographical area. For example, some Asian and European ser-vice providers have licenses in both 900 MHz and 1800 MHz bands. Some North American service providers operate in both 800 MHz and 1900 MHz bands.• A building owner will often allow service providers to provide wireless service in their building only if they cooperate and share the infrastructure equipment and distribution system. Delays in service implementation and loss of revenue occur when the competing service providers do not agree on how to share the equipment and installation costs.Additional distribution cabling infrastructure, beyond initial requirements, often is installed to accommodate adding Operators or services or to enhance capacity by sec-torizing the distribution equipment at a later time.

ESystem OperationFigure 2-6 Example Neutral Host ApplicationNeutral host systems are deployed as shared or dedicated systems.•Shared System: Multiple wireless Operators use the same set of LGCell hard-ware to distribute RF signals.•Dedicated System: Each Operator uses an independent LGCell system.In order to simplify coverage planning and minimize installation costs, the equipment is “clustered” and installed in groups. The number of Hubs and RAUs required for a system is determined by their ability to be shared.The configuration shown in Figure 2-7 supports up to 7 Operator bands.LGCell Main HubOperator 1RAUCat-5 Cable:RAURAULGCell Expansion HubOp. 1 and/or Op. 2LGCell Main HubOp. 1 and/or Op. 2Installed now,used nowCat-5 Cable:Installed now,used laterFiber Optic Cable:Installed now,used laterFiber Optic Cable:Installed now,used nowFuture LGCell EquipmentFuture LGCell EquipmentLGCell Expansion HubOperator 1(Operator 2 in the future)

They are either open or short circuit as shown in the following table.• Major ErrorThe Main Hub senses, then latches, major errors, which can be monitored via the alarm port’s contact closures. Red or unlit (off) LEDs on the front panel indicate when an alarm is detected. (Refer to Section 10.2 on page 10-2 for help trouble-shooting using LEDs.)The major error contact can be brought back to the BTS for alarm monitoring if the BTS provides +40V DC or less.Figure 3-8 Monitoring Main Hub Alarms from the BTS• Error LatchThe error latch provides historical information for troubleshooting when you use an external alarm monitor. The recommended method of clearing an error latch is to connect pin 8 (error reset) to pin 1 (+10V) for at least one second. You can power cycle the unit to clear the error latch, but if you are not monitoring alarms externally, there is no need to do this.

PN 8100-40 LGCell 4.0 Installation, Operation, and Reference Manual 7-1620004-0 Rev. ESECTION 7 Designing an LGCell SolutionDesigning an LGCell solution is ultimately a matter of determining coverage and capacity needs. This requires the following steps:1. Determine the wireless service provider’s requirements.This information is usually supplied by the service provider:• Frequency (i.e., 850 MHz)• Band (i.e., “A” band in the Cellular spectrum)• Protocol (i.e., TDMA, CDMA, GSM, iDEN)• Peak capacity requirement (this, and whether or not the building will be split into sectors, determines the number of carriers that the LGCell will have to transmit)• Design goal (RSSI, received signal strength at the wireless handset, i.e., –85 dBm)The design goal is always a stronger signal than the cell phone needs. It includes inherent factors which will affect performance (see Section 7.4.1 on page 7-29).• RF source (base station or BDA), type of equipment if possible2. Determine the power per carrier and input power from the base station or BDA into the Main Hub: Section 7.1, “Maximum Output Power per Carrier at RAU,” on page 7-3.The maximum power per carrier is a function of the number of RF carriers, the carrier headroom requirement, signal quality issues, regulatory emissions require-ments, and the LGCell’s RF performance. The power per carrier decreases as the number of carriers increases. 3. Determine the in-building environment: Section 7.2, “Estimating RF Cover-age,” on page 7-15.• Determine which areas of the building require coverage (entire building, public areas, parking levels, etc.)

Designing an LGCell Solution7-2 LGCell 4.0 Installation, Operation, and Reference Manual PN 8100-40620004-0 Rev. E• Obtain floor plans to determine floor space of building and the wall layout of the proposed areas to be covered. Floor plans will also be useful when you are selecting antenna locations.• If possible, determine the building’s construction materials (sheetrock, metal, concrete, etc.)• Determine type of environment– Open layout (e.g., a convention center)– Dense, close walls (e.g., a hospital)– Mixed use (e.g., an office building with hard wall offices and cubicles)4. Develop an RF link budget: Section 7.4, “Link Budget Analysis,” on page 7-28.Knowing the power per carrier, you can calculate an RF link budget which is used to predict how much propagation loss can be allowed in the system, while still providing satisfactory performance throughout the area being covered. The link budget is a methodical way to derive a “design goal”. If the design goal is pro-vided in advance, the link budget is simply: allowable RF loss = max. power per carrier – design goal.5. Determine the appropriate estimated path loss slope that corresponds to the type of building and its layout, and estimate the coverage distance for each RAU: Section 7.2, “Estimating RF Coverage,” on page 7-15.The path loss slope (PLS), which gives a value to the RF propagation characteris-tics within the building, is used to convert the RF link budget into an estimate of the coverage distance per antenna. This will help establish the LGCell equipment quantities you will need. The actual path loss slope that corresponds to the spe-cific RF environment inside the building can also be determined empirically by performing an RF site-survey of the building. This involves transmitting a cali-brated tone for a fixed antenna and making measurements with a mobile antenna throughout the area surrounding the transmitter.6. Determine the items required to connect to the base station: Section 7.5, “Connecting a Main Hub to a Base Station,” on page 7-41.Once you know the quantities of LGCell equipment you will use, you can deter-mine the accessories (combiners/dividers, surge suppressors, repeaters, attenua-tors, circulators, etc.) that are required to connect the system to the base station.The individual elements that must be considered in designing an LGCell solution are discussed in the following sections.

PN 8100-40 Help Hot Line (U.S. only): 1-800-530-9960 7-3620004-0 Rev. EMaximum Output Power per Carrier at RAU7.1 Maximum Output Power per Carrier at RAUThe following tables show the recommended maximum power per carrier out of the RAU SMA connector for different frequencies, formats, and numbers of carriers. These limits are dictated by RF signal quality and regulatory emissions issues. The maximum input power to the Main Hub is determined by subtracting the system gain from the maximum output power of the RAU. For most systems the gain is 0 dB. Exceptions are the duplex port for the Cellular LGCell (30 dB gain) and the duplex port of the PCS LGCell (40 dB gain).Therefore, when you connect a Main Hub to a base station or repeater, the RF power per carrier usually needs to be attenuated in order to avoid exceeding the LGCell’s maximum composite output power.Refer to Section 7.6, “Designing for a Neutral Host System,” on page 7-45 when combining frequencies or protocols on a single Main Hub.WARNING: Exceeding the maximum input power could cause perma-nent damage to the Main Hub.

EAllowing for Future Capacity GrowthSometimes an LGCell deployment initially is used to enhance coverage. Later that same system may also need to provide increased capacity. Thus, the initial deploy-ment might only transmit two carriers but need to transmit four carriers later. There are two options for dealing with this scenario:1. Design the initial coverage with a maximum power per carrier for four carriers. 2. Design the initial coverage for two carriers but leave Expansion Hub ports unused. These ports can be used later if coverage holes are discovered once the power per carrier is lowered to accommodate the two additional carriers.

EEstimating RF Coverage7.2 Estimating RF CoverageThe maximum power per carrier (based on the number and type of RF carriers that are being transmitted) and the minimum acceptable received power at the wireless device (i.e., RSSI, the design goal) establish the RF link budget, and consequently the path loss between the antenna and the wireless device.Figure 7-1 Determining Path Loss between the Antenna and the Wireless Device(P + G) – RSSI = PL (1)The path loss (PL) is the loss in decibels (dB) between the antenna and the wireless device. The distance, d, from the antenna corresponding to this path loss can be calcu-lated using the path loss equation in Section 7.2.1 or in Section 7.2.3.The losses due to the coaxial cable that connects the RAU to the antenna are not included in this equation because, typically, the cable is short and the losses are mod-est. However, if further precision is desired, you can use the coaxial cable losses listed in the following table.Table 7-11 Coaxial Cable LossesLength of CableLoss at 800 MHz(dB)Loss at1900 MHz(dB)0.9 m (3 ft) 0.6 0.81.8 m (6 ft) 1.0 1.53.0 m (10 ft) 1.5 2.3RAUP = power per dAntenna and Gain (G)RSSI = power at thewireless devicecarrier from the RAU

E7.2.3 Coverage DistanceEquations (1) and (2), on pages 7-15 and 7-16, respectively, can be used to estimate the distance from the antenna to where the RF signal decreases to the minimum acceptable level at the wireless device.Equation (2) can be simplified to:PL = 20log(4πf/c) + PLSlogD (3)where PLS is chosen to account for partition losses. Because different frequencies penetrate partitions with different losses, the value of PLS will vary depending on the frequency.For simplicity, Equation (3) can be used to estimate the coverage distance of an antenna that is connected to an RAU, for a given path loss, frequency, and type of in-building environment.Table 7-14 gives the value of the first term of Equation (3) (i.e., (20log(4πf/c)) for various frequency bands.Table 7-14 Frequency Bands and the Value of the first Term in Equation (3)Band (MHz) Mid-Band Frequency (MHz) 20log(4πf/c)Uplink Downlink800 Cellularaa.

Design goals:• Cellular (859 MHz = average of the lowest uplink and the highest downlink frequency in 800 MHz Cellular band)• TDMA provider• 6 TDMA carriers in the system• –85 dBm design goal (to 95% of the building) — the minimum received power at the wireless device• Base station with simplex RF connections2. Power Per Carrier: The tables in Section 7.1, “Maximum Output Power per Car-rier at RAU,” on page 7-3 provide maximum power per carrier information. The 800 MHz Cellular table (on page 7-4) indicates that the LGCell can support 6 car-riers with a typical power per carrier of 4.5 dBm.4.5 dBm per carrier would be the typical RF signal into the Main Hub’s FOR-WARD (downlink) port. If the duplex port is used, you must take into account the gain of the port (Table 7-22 on page 7-25) and adjust the input power accordingly. For example, the duplex port on the 800 MHz LGCell provides 30 dB gain. Therefore, the input power must be no greater than –25.5 dBm per carrier (4.5 dBm – 30 dBm). Similarly, the PCS LGCell has a duplex port gain of 40 dB. All other systems have 0 dB gain through all ports.3. Building information:• 8 floor building with 9,290 sq. meters (100,000 sq. ft.) per floor; total 74,322 sq. meters (800,000 sq. ft.)• Walls are sheetrock construction; suspended ceiling tiles• Antennas used will be omni-directional, ceiling mounted• Standard office environment, 50% hard wall offices and 50% cubicles4. Link Budget: In this example, a design goal of –85 dBm is used. Suppose 3 dBi omni-directional antennas are used in the design. Then, the maximum RF propa-gation loss should be no more than 92.5 dB (4.5 dBm + 3 dBi + 85 dBm) over 95% of the area being covered. It is important to note that a design goal such as –85 dBm is usually derived taking into account multipath fading and log-normal shadowing characteristics. Thus, this design goal will only be met “on average” over 95% of the area being covered. At any given point, a fade may bring the sig-nal level underneath the design goal.Note that this method of calculating a link budget is only for the downlink path. For information to calculate link budgets for both the downlink and uplink paths, see Section 7.4 on page 7-28.5. Path Loss Slope: For a rough estimate, Table 7-13, “Estimated Path Loss Slope for Different In-Building Environments” on page 7-17, shows that a building with 50% hard wall offices and 50% cubicles, at 859 MHz, has an approximate path loss slope (PLS) of 37.6. Given the RF link budget of 92.3 dB, the distance of coverage from each RAU will be 42 meters (138 ft). This corresponds to a coverage area of 5,641

Designing an LGCell Solution7-24 LGCell 4.0 Installation, Operation, and Reference Manual PN 8100-40620004-0 Rev. Esq. meters (60,719 sq. ft.) per RAU (see Section 7.2.1 for details on path loss esti-mation). For this case we assumed a circular radiation pattern, though the actual area covered will depend upon the pattern of the antenna and the obstructions in the facility.If the area to be covered is essentially an unobstructed hallway with some cover-age for the offices on either side of the hallway, a more aggressive design using a lower PLS should be used.6. Equipment Required: Since you know the building size, you can now estimate the LGCell equipment quantities that will be needed. Before any RF levels are tested in the building, you can estimate that 2 antennas per level will be needed.a. 2 antennas per floor × 8 floors = 16 RAUsb. 16 RAUs ÷ 4 (max 4 RAUs per Expansion Hub) = 4 Expansion Hubsc. 4 Expansion Hubs ÷ 4 (max 4 Expansion Hubs per Main Hub) = 1 Main HubCheck that the MMF and Cat-5 cable distances are as recommended. If the dis-tances differ, use the tables in Section 7.3, “System Gain,” on page 7-25 to deter-mine system gains or losses. The path loss may need to be recalculated to assure adequate signal levels in the required coverage distance.The above estimates assume that all cable length requirements are met. If Expansion Hubs cannot be placed so that the RAUs are within the distance requirement, addi-tional Expansion Hubs may need to be placed closer to the required RAUs locations.An RF Site Survey and Building Evaluation is required to accurately establish the LGCell equipment quantities required for the building. The site survey measures the RF losses within the building to determine the actual PLS, which will be used in the final path loss formula to determine the actual requirements of the LGCell.

The optical loss of 1 km (3300 ft) of MMF cable ranges from about 0.6 to 1.0 dB optical, depending on the type of cable (i.e., riser zip-cord, loose tube, slotted core, etc.).NOTE: The maximum input power to the Main Hub is equal to the maximum output power of the RAU minus the system gain. For example, for a Cellular system with 6 TDMA carriers, the maximum output power is 4.5 dBm per carrier. If the duplex port is used, the maximum input power to the Main Hub should be no greater than –25.5 dBm per carrier.Table 7-22 System Gain when using Duplex/Simplex PortsLGCell Frequency and FormatSystem Gain (dB)Duplex Port Simplex Ports800 MHz Cellular 30 0800 MHz iDEN 0 0900 MHz GSM, EGSM 0 01800 MHz GSM 0 01900 MHz PCS 40 0
