PN 8700-10 InterReach Unison User Guide and Reference Manual 2-1620003-0PRELIMINARYSECTION 2 InterReach™ Unison System Description2.1 System OverviewInterReach™ Unison is an intelligent fiber optic wireless networking system that is designed to handle both wireless voice and data communications and provide high-quality, ubiquitous, seamless access to the Cellular or Personal Communications Services (PCS) network in any public or private facility, including:• Campus environments•Airports• Office buildings• Shopping Malls• Hospitals• Public Facilities (convention centers, sports venues, etc.)Unlike other wireless distribution alternatives, Unison is an intelligent active system, using microprocessors to enable key capabilities such as software-selectable band set-tings, automatic gain control, ability to incrementally adjust downlink/uplink gain, end-to-end alarming of all components and the associated cable infrastructure, and a host of additional capabilities.The Unison system supports major Cellular/PCS standards and air interface protocols in use around the world, including:• Frequencies: 800 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz• Protocols: AMPS, TDMA, CDMA, DCS, GSM, EGSM, iDEN, CDPD, EDGE, GPRS, WCDMA
InterReach™ Unison System Description PRELIMINARY2-2 InterReach Unison User Guide and Reference Manual PN 8700-10620003-0Key System Features•Superior RF performance, particularly in the areas of IP3 and noise figure.•High downlink composite power (+26 dBm), IP3 (+38 dBm) and low uplink noise figure (22 dB for a system with 8 RAUs), enables support of a large number of channels and larger coverage footprint per antenna.• The Main Hub and the Expansion Hub are software configurable. Thus, the fre-quency band can be field configured.• The system supports flexible cabling alternatives, allowing the use of either mul-timode or single-mode fiber (in addition to standard Cat-5 or Cat-6 [Cat-5/6] twisted pair). Cabling type can be selected to meet the resident cabling infrastruc-ture of the facility and unique building topologies.•Extended system “reach”. Using multimode fiber, fiber runs can be as long as 1.5 kilometers. Alternately, with single mode fiber the fiber run can be as long as 6 kilometers (creating a total system “wingspan” of 12 kilometers). And the Cat-5/6 twisted pair cable run can be up to 100 meters recommended maximum (150 meters with RF performance degradation).•Flexible RF configuration capabilities, including:• System gain:– Ability to manually set gain in 1 dB steps on both downlink and uplink.• RAU:– RAU uplink and downlink gain can be attenuated 10 dB.– Uplink level control protects the system from input overload and can be optimized for either a single operator or multi-operators/protocols.– VSWR check on RAU reports if there is a problem with the antenna.• The system firmware effectively “future proofs” the product. When any modi-fications are made to the product, including the addition of new software capabili-ties/services, systems that have already been installed can be upgraded simply by downloading new firmware (either locally or remotely).•Extensive OA&M capabilities, including fault isolation to the field replaceable unit, automatic reporting of all warnings and alarms, and user-friendly graphi-cal-user interface OA&M software packages.

The maximum configuration of a system is one Main Hub, four Expansion Hubs, and 32 RAUs (1-4-32). Multiple systems can be com-bined to provide larger configurations.
InterReach™ Unison System Description PRELIMINARY2-4 InterReach Unison User Guide and Reference Manual PN 8700-10620003-02.3 System SoftwareThe AdminManager software runs on a Laptop PC which is either directly connected to the DB-9 RS-232 male connector on the Main Hub’s front panel or is remotely communicating through a modem that is connected to the DB-9 connector on the Main Hub’s rear panel. The AdminManager communicates with one Main Hub, and its downstream units, at a time.• Connected locally, you can access the Installation Wizard which lets you configure a newly installed system, or access the Configuration Panel which lets you query system status, configure a newly added or swapped unit, or change system parame-ters.• Connected remotely, AdminManager initiates communications with the Main Hub. You can access a read-only Configuration Panel which lets you check system status to help you determine if an on-site visit is required.Refer to Section 7 for information about installing and using the AdminManager soft-ware.Alternately, an LGC Wireless OA&M software application called the OpsConsole is available separately. The OpsConsole lets you manage, monitor, and maintain multi-ple sites and systems from a centralized location. This software is described in a sep-arate LGC document (part number 8701-10).

All events occurring in a system, defined as a Main Hub and all of its associated Expansion Hubs and Remote Access Units, are automatically reported to the Main Hub. The Main Hub monitors system status and communicates that status using the following methods:• Normally closed (NC) alarm contact closures can be tied to standard NC alarm monitoring systems or directly to a base station for alarm monitoring.• The Main Hub’s front panel serial port connects directly to a PC (for local access) or to a modem (for remote access).Figure 2-1 OA&M CommunicationsPSTNRS-232RS-232 EthernetPC/LaptoprunningModemMain HubModemMain HubTCP/IPRS-232ENET/232ConverterCat-5/6RS-232SC/APCMain HubSC/APCRJ-45Expansion HubRJ-45Remote Access UnitFiberMain HubAdminManagerOr OpsConsoleAdminManager can only initiatecommunications with a remotelymodem calls.Use the OpsConsole for monitoringand receiving communications frominstalled system; it cannot receiveremotely installed systems.
InterReach™ Unison System Description PRELIMINARY2-6 InterReach Unison User Guide and Reference Manual PN 8700-10620003-02.4.1 Configuring, Maintaining, and Monitoring Unison LocallyEach Main Hub, Expansion Hub, and RAU in the system constantly monitors itself and its downstream units for internal fault and warning conditions. The results of the monitoring are stored in memory and compared against new results.The Expansion Hubs monitor their RAUs and store their status in memory. The Main Hub monitors its Expansion Hubs and stores their status and the status of the RAUs in its memory. When a unit detects a change in status, a fault or warning is reported.

One reason you may want to use this setting is to reduce the RAU’s output power when an RAU is located near an exterior wall of a building and its RF signal is going beyond the wall to the outside of the building, where it can negatively affect the outdoor macro system.The following table shows some examples of how the 10 dB attenuation setting affects coverage distance. These examples assume a 0 dB gain system, a 3 dBi gain antenna, and the difference between a –85 dB and a –75 dB design.You can use the following formula to calculate the reduction in distance covered.•dorig = original distance•dnew = new distance with 10 dB attenuation enabled• PLS = path loss slope [dB]dnew = (10–10/PLS)dorigExamples:dnew = 0.31 dorig for PLS = 20 dB (free space)dnew = 0.46 dorig for PLS = 30 dBFrequency Environment Reduction in Coverage Distance800 MHz Open, like a parking garage 24 meters (80 feet)800 MHz Heavily walled, like a Hospital 12.5 meters (41 feet)1900 MHz Open, like a parking garage 24 meters (80 feet)1900 MHz Heavily walled, like a Hospital 9 meters (30 feet)

PN 8700-10 InterReach Unison User Guide and Reference Manual 8-1620003-0PRELIMINARYSECTION 8 Designing a Unison SolutionDesigning a Unison 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 system 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 8.4.1 on page 8-33).• 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 8.1, “Maximum Output Power per Carrier at RAU,” on page 8-3.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 Unison’s RF performance. The power per carrier decreases as the number of carriers increases. 3. Determine the in-building environment: Section 8.2, “Estimating RF Cover-age,” on page 8-19.• Determine which areas of the building require coverage (entire building, public areas, parking levels, etc.)
Designing a Unison Solution PRELIMINARY8-2 InterReach Unison User Guide and Reference Manual PN 8700-10620003-0• 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 8.4, “Link Budget Analysis,” on page 8-32.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 8.2, “Estimating RF Coverage,” on page 8-19.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 Unison 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 8.6, “Connecting a Main Hub to a Base Station,” on page 8-47.Once you know the quantities of Unison 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 a Unison solution are discussed in the following sections.

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. System gain is software selectable from 0 dB to 15 dB in 1 dB steps. Additionally, both the uplink and downlink RAU gain can be reduced by 10 dB.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 Unison’s max-imum composite output power.(reference to “composite” power. PS)Refer to Section 8.7, “Designing for a Neutral Host System,” on page 8-51 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.

Designing a Unison Solution PRELIMINARY8-18 InterReach Unison User Guide and Reference Manual PN 8700-10620003-0Allowing for Future Capacity GrowthSometimes a Unison 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 (increase this number? PS) 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.

Because different frequencies penetrate partitions with different losses, the value of PLS will vary depending on the frequency.Table 8-17 shows estimated path loss slope (PLS) for various environments that have different “clutter” (i.e., objects that attenuate the RF signals, such as walls, partitions, stairwells, equipment racks, etc.)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 8-17 Estimated Path Loss Slope for Different In-Building EnvironmentsFacility PLS for 800/900 MHz PLS for 1800/1900 MHzManufacturing 35 32Hospital 39.4 38.1Airport 35 32Retail 36.1 33.1Warehouse 35 32Parking Garage 33.7 30.1Office: 80% cubicle/20% hard wall 36.1 33.1Office: 50% cubicle/50% hard wall 37.6 34.8Office: 20% cubicle/80% hard wall 39.4 38.1

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 8.1, “Maximum Output Power per Carrier at RAU,” on page 8-3 provide maximum power per carrier information. The 800 MHz TDMA table (on page 8-5) indicates that Unison can support 6 car-riers with a recommended maximum power per carrier of 10.5 dBm. The input power should be set to the desired output power minus the system gain.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 98.5 dB (10.5 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.

Path Loss Slope: For a rough estimate, Table 8-17, “Estimated Path Loss Slope for Different In-Building Environments” on page 8-21, 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 98.5 dB, the distance of coverage from each RAU will be 60/62 meters (198/203 ft). This corresponds to a coverage area of 11,465/12,079 sq. meters (123,409/129,952 sq. ft.) per RAU (see Section 8.2.1 for details on path loss estimation). For this case we assumed a circu-lar radiation pattern, though the actual area covered will depend upon the pattern of the antenna and the obstructions in the facility.

The 1900 MHz CDMA table (on page 8-15) indicates that Unison can support 8 carriers with a recommended maximum power per carrier of 6.5 dBm. The input power should be set to the desired output power minus the system gain.3.

Designing a Unison Solution PRELIMINARY8-32 InterReach Unison User Guide and Reference Manual PN 8700-10620003-08.4 Link Budget AnalysisA link budget is a methodical way to account for the gains and losses in an RF system so that the quality of coverage can be predicted. The end result can often be stated as a “design goal” in which the coverage is determined by the maximum distance from each RAU before the signal strength falls beneath that goal.One key feature of the link budget is the maximum power per carrier discussed in Section 8.1. While the maximum power per carrier is important as far as emissions and signal quality requirements are concerned, it is critical that the maximum signal into the Main Hub never exceed 1W (+30 dBm). Composite power levels above this limit will cause damage to the Main Hub.WARNING: Exceeding the maximum input power of 1W (+30 dBm) could cause permanent damage to the Main Hub.
PN 8700-10 Help Hot Line (U.S. only): 1-800-530-9960 8-33620003-0PRELIMINARY Elements of a Link Budget for Narrowband Standards8.4.1 Elements of a Link Budget for Narrowband StandardsThe link budget represents a typical calculation that might be used to determine how much path loss can be afforded in a Unison design. This link budget analyzes both the downlink and uplink paths. For most configurations, the downlink requires lower path loss and is therefore the limiting factor in the system design. It is for this reason that a predetermined “design goal” for the downlink is sufficient to predict coverage distance.The link budget is organized in a simple manner: the transmitted power is calculated, the airlink losses due to fading and body loss are summed, and the receiver sensitivity (minimum level a signal can be received for acceptable call quality) is calculated. The maximum allowable path loss (in dB) is the difference between the transmitted power, less the airlink losses, and the receiver sensitivity. From the path loss, the maximum coverage distance can be estimated using the path loss formula presented in Section 8.2.1.Table 8-28 provides link budget considerations for narrowband systems.Table 8-28 Link Budget Considerations for Narrowband SystemsConsideration DescriptionBTS Transmit Power The power per carrier transmitted from the base station outputAttenuation between BTS and UnisonThis includes all losses: cable, attenuator, splitter/combiner, and so forth. On the downlink, attenuation must be chosen so that the maximum power per carrier going into the Main Hub does not exceed the levels given in Section 8.1. On the uplink, attenuation is chosen to keep the maximum uplink signal and noise level low enough to prevent base station alarms but small enough not to cause degradation in the system sensitivity.If the Unison noise figure minus the attenuation is at least 10 dB higher than the BTS noise figure, the system noise figure will be approximately that of Unison alone. See Section 8.6 for ways to inde-pendently set the uplink and downlink attenuations between the base station and Unison.Unison Gain This is the system gain (see Table 8-26 on page 8-29)Antenna Gain The radiated output power includes antenna gain. For example, if you use a 3 dBi antenna at the RAU that is transmitting 0 dBm per carrier, the effective radiated power (relative to an isotropic radiator) is 3 dBm per carrier.BTS Noise Figure This is the effective noise floor of the base station input (usually base station sensitivity is this effec-tive noise floor plus a certain C/I ratio).Unison Noise Figure This is Unison’s uplink noise figure, which varies depending on the number of Expansion Hubs and RAUs, and the frequency band. Unison’s uplink noise figure is specified for a 1-1-4 configuration. Thus, the noise figure for a Unison system (or multiple systems whose uplink ports are power com-bined) will be NF(1-1-4) + 10*log(# of Expansion Hubs). This represents an upper-bound because the noise figure is lower if any of the Expansion Hub’s RAU ports are not used.
Designing a Unison Solution PRELIMINARY8-34 InterReach Unison User Guide and Reference Manual PN 8700-10620003-0Thermal Noise This is the noise level in the signal bandwidth (BW). Thermal noise power = –174 dBm/Hz + 10Log(BW).Required C/I ratio For each wireless standard a certain C/I (carrier to interference) ratio is needed to obtain acceptable demodulation performance. For narrowband systems, (TDMA, GSM, EDGE, iDEN, AMPS) this level varies from about 9 dB to 20 dB.Mobile Transmit PowerThe maximum power the mobile can transmit (power transmitted at highest power level setting).Multipath Fade MarginThis margin allows for a certain level of fading due to multipath interference. Inside buildings there is often one or more fairly strong signals and many weaker signals arriving from reflections and dif-fraction. Signals arriving from multiple paths add constructively or destructively. This margin accounts for the possibility of destructive multipath interference. In RF site surveys this margin will not appear because it will be averaged out over power level samples taken over many locations.Log-normal Fade MarginThis margin adds an allowance for RF shadowing due to objects obstructing the direct path between the mobile equipment and the RAU. In RF site surveys, this shadowing will not appear because it will be averaged out over power level samples taken over many locations.Body Loss This accounts for RF attenuation caused by the user’s head and body.Minimum Received Signal LevelThis is also referred to as the “design goal”. The link budget says that you can achieve adequate cov-erage if the signal level is, on average, above this level over 95% of the area covered, for example.Table 8-28 Link Budget Considerations for Narrowband Systems (continued)Consideration DescriptionProtocol Signal Bandwidth Thermal NoiseTDMA 30 kHz –129 dBmCDMA 1.25 MHz –113 dBm spread-spectrum, remove?

PN 8700-10 Help Hot Line (U.S. only): 1-800-530-9960 8-37620003-0PRELIMINARY Elements of a Link Budget for CDMA Standards8.4.3 Elements of a Link Budget for CDMA StandardsA CDMA link budget is slightly more complicated because the spread spectrum nature of CDMA must be considered. Unlike narrowband standards such as TDMA and GSM, CDMA signals are spread over a relatively wide frequency band. Upon reception, the CDMA signal is de-spread. In the de-spreading process the power in the received signal becomes concentrated into a narrow band, whereas the noise level remains unchanged. Hence, the signal-to-noise ratio of the de-spread signal is higher than that of the CDMA signal before de-spreading. This increase is called processing gain. For IS-95 and J-STD-008, the processing gain is 21 dB or 19 dB depending on the user data rate (9.6 Kbps for rate set 1 and 14.4 Kbps for rate set 2, respectively). Because of the processing gain, a CDMA signal (comprising one Walsh code channel within the composite CDMA signal) can be received at a lower level than that required for narrowband signals. A reasonable level is –95 dBm, which results in about –85 dBm composite as shown below.An important issue to keep in mind is that the downlink CDMA signal is composed of many orthogonal channels: pilot, paging, sync, and traffic. The composite power level is the sum of the powers from the individual channels. An example is given in the following table.This table assumes that there are 15 active traffic channels operating with 50% voice activity (so that the total power adds up to 100%). Notice that the pilot and sync chan-nels together contribute about 25% of the power. When measuring the power in a CDMA signal you must be aware that if only the pilot and sync channels are active, the power level will be about 6 to 7 dB lower than the maximum power level you can expect when all voice channels are active. The implication is that if only the pilot and sync channels are active, and the maximum power per carrier table says that you should not exceed 10 dBm for a CDMA signal, for example, then you should set the attenuation between the base station and the Main Hub so that the Main Hub receives 3 dBm (assuming 0 dB system gain).An additional consideration for CDMA systems is that the uplink and downlink paths should be gain and noise balanced. This is required for proper operation of soft-hand-off to the outdoor network as well as preventing excess interference that is caused by mobiles on the indoor system transmitting at power levels that are not coordinated with the outdoor mobiles. This balance is achieved if the power level transmitted by the mobiles under close-loop power control is similar to the power level transmitted under open-loop power control. The open-loop power control equation isPTX + PRX = –73 dBm (for Cellular, IS-95)Table 8-29 Distribution of Power within a CDMA SignalChannel Walsh Code Number Relative Power LevelPilot 0 20% –7.0 dBSync 32 5% –13.3 dBPrimary Paging 1 19% –7.3 dBTraffic 8–31, 33–63 9% (per traffic channel) –10.3 dB
Designing a Unison Solution PRELIMINARY8-38 InterReach Unison User Guide and Reference Manual PN 8700-10620003-0PTX + PRX = –76 dBm (for PCS, J-STD-008)where PTX is the mobile’s transmitted power and PRX is the power received by the mobile.The power level transmitted under closed-loop power control is adjusted by the base station to achieve a certain Eb/N0 (explained in Table 8-30 on page 8-38). The differ-ence between these power levels, ∆P, can be estimated by comparing the power radi-ated from the RAU, Pdownink, to the minimum received signal, Puplink, at the RAU:∆P = Pdownink + Puplink + 73 dBm (for Cellular)∆P = Pdownink + Puplink + 76 dBm (for PCS)It’s a good idea to keep –12 dB < ∆P < 12 dB.Table 8-30 provides link budget considerations for CDMA systems.Table 8-30 Additional Link Budget Considerations for CDMA SystemsConsideration DescriptionMultipath Fade MarginThe multipath fade margin can be reduced (by at least 3 dB) by using different lengths of optical fiber (this is called “delay diversity”). The delay over fiber is approximately 5µS/km. If the difference in fiber lengths to Expansion Hubs with overlapping coverage areas produces at least 1 chip (0.8µS) delay of one path relative to the other, then the multipaths’ signals can be resolved and processed independently by the base station’s rake receiver. A CDMA signal traveling through 163 meters of MMF cable will be delayed by approximately one chip. Power per car-rier, downlinkThis depends on how many channels are active. For example, the signal will be about 7 dB lower if only the pilot, sync, and paging channels are active compared to a fully-loaded CDMA signal. Furthermore, in the CDMA forward link, voice channels are turned off when the user is not speaking. On average this is assumed to be about 50% of the time. So, in the spreadsheet, both the power per Walsh code channel (rep-resenting how much signal a mobile will receive on the Walsh code that it is de-spreading) and the total power are used.The channel power is needed to determine the maximum path loss, and the total power is needed to deter-mine how hard the Unison system is being driven.The total power for a fully-loaded CDMA signal is given by (approximately):total power = voice channel power + 13 dB + 10log10 (50%)= voice channel power + 10 dBInformation Rate This is simply 10log10(9.6 Kbps) = 40 dB for rate set 110log10(14.4 Kbps) = 42 dB for rate set 2Process Gain The process of de-spreading the desired signal boosts that signal relative to the noise and interference. This gain needs to be included in the link budget. In the following formulas, PG = process gain:PG = 10log10(1.25 MHz / 9.6 Kbps) = 21 dB rate set 1PG = 10log10(1.25 MHz / 14.4 Kbps) = 19 dB rate set 2Note that the process gain can also be expressed as 10log10 (CDMA bandwidth) minus the information rate.

The combined CDMA signals will interfere with each other.• Try to minimize overlap between in-building coverage areas that utilize different sectors, as well as in-building coverage and outdoor coverage areas. This is impor-tant because any area in which more than one dominant pilot signal (at the same frequency) is measured by the mobile will result in soft-handoff. Soft-handoff decreases the overall network capacity by allocating multiple channel resources to a single mobile phone.Eb/No This is the energy-per-bit divided by the received noise and interference. It’s the CDMA equivalent of sig-nal-to-noise ratio (SNR). This figure depends on the mobile’s receiver and the multipath environment. For example, the multipath delays inside a building are usually too small for a rake receiver in the mobile (or base station) to resolve and coherently combine multipath components. However, if artificial delay can be introduced by, for instance, using different lengths of cable, then the required Eb/No will be lower and the multipath fade margin in the link budget can be reduced in some cases.If the receiver noise figure is NF (dB), then the receive sensitivity (dBm) is given by:Psensitivity = NF + Eb/No + thermal noise in a 1.25 MHz band – PG= NF + Eb/No – 113 (dBm/1.25 MHz) – PGNoise Rise On the uplink, the noise floor is determined not only by the Unison system, but also by the number of mobiles that are transmitting. This is because when the base station attempts to de-spread a particular mobile’s signal, all other mobile signals appear to be noise. Because the noise floor rises as more mobiles try to communicate with a base station, the more mobiles there are, the more power they have to transmit. Hence, the noise floor rises rapidly:noise rise = 10log10(1 / (1 – loading))where loading is the number of users as a percentage of the theoretical maximum number of users.Typically, a base station is set to limit the loading to 75%. This noise ratio must be included in the link budget as a worst-case condition for uplink sensitivity. If there are less users than 75% of the maximum, then the uplink coverage will be better than predicted.Hand-off Gain CDMA supports soft hand-off, a process by which the mobile communicates simultaneously with more than one base station or more than one sector of a base station. Soft hand-off provides improved receive sensitivity because there are two or more receivers or transmitters involved. A line for hand-off gain is included in the CDMA link budgets worksheet although the gain is set to 0 dB because the in-building system will probably be designed to limit soft-handoff.Table 8-30 Additional Link Budget Considerations for CDMA Systems Consideration Description

Additional considerations for such an application of the Unison are: • Sizing the gain and output power requirements for a bi-directional amplifier (repeater).• Ensuring that noise radiated on the uplink from the in-building system does not cause the outdoor base station to become desensitized to wireless handsets in the outdoor network.• Filtering out signals that lie in adjacent frequency bands. For instance, if you are providing coverage for Cellular B-band operation it may be necessary to filter out the A, A’ and A” bands which may contain strong signals from other outdoor base stations.Further information on these issues can be found in LGC Wireless’ application notes for re-radiation applications.Rich, are we supporting re-rad applications?

The connector losses associated with mating to these connectors is accounted for in the design and should not be included as ele-ments of the Optical Power Budget. The reason is that when the Optical Power Bud-get is defined, measurements are taken with these connectors in place.The Main Hub/Expansion Hub link uses one fiber strand and its Optical Power Budget is:• Uplink: 5.5 dB @ 1550 nm• Downlink: 7 dB @ 1310 nmThe following figure shows what is to be included when calculating Optical Power Budget losses.Figure 1 Losses to be Included in Optical Power BudgetMainHub ExpansionHubMated SC/APC ConnectorsTo be included in Optical Power BudgetMH EHEquipment RoomOSP POEEquipment RoomISP Cable ISP CableOSP CableSMF JumperFDP SC/APC Bulk HeadFusion SpliceOSP POEOSP = Outside PlantISP = Inside PlantPOE = Point of Entry

For this example, assume that the base station will have simplex connections, one uplink and one downlink. Each of these connections will need to be divided to equilibrate power for each Main Hub. For example, two Main Hubs will require a 2×1 combiner/divider; four Main Hubs will require a 4×1 com-biner/divider; and so on.Figure 8-2 Connecting Main Hubs to a Simplex Base StationWhen connecting a Unison Main Hub to a base station, also consider the following:1. The downlink power from the base station must be attenuated enough so that the power radiated by the RAU does not exceed the maximum power per carrier listed in Section 8.1, “Maximum Output Power per Carrier at RAU,” on page 8-3.2. The uplink attenuation should be small enough that the sensitivity of the overall system is limited by Unison, not by the attenuator. However, some base stations will trigger alarms if the noise or signal levels are too high. In this case the attenu-ation will have to be large enough to prevent this from happening.If, in an area covered by Unison, a mobile phone indicates good signal strength but consistently has difficulty completing calls, it is possible that the attenuation between Unison and the base station needs to be adjusted. In other words, it is possible that if the uplink is over-attenuated, the downlink power will provide good coverage, but the uplink coverage distance will be small.When there is an excessive amount of loss between the Main Hub uplink and the base station, the uplink system gain can be increased to as much as 15 dB to prevent a reduction in the overall system sensitivity.Base Station2 × 1 combiner/dividerDownlink/ForwardMain Hub 1Main Hub 2Uplink/Reverse

For a simplex base station, eliminate the circulator and connect the simplex ports of the base station to the simplex ports of the Main Hub. Add attenuators to reg-ulate the power appropriately.Figure 8-3 Main Hub to Duplex Base Station or Repeater ConnectionsDuplexBase Station Main HubForwardReverseA3A1A2• A typical circulator has an IP3 of +70dBm. If you drive the circulator too hard it will produce intermods that are bigger than the intermods produced by Unison. The IP3 at the Forward port input of the Main Hub is approximately +38 dBm. The IP3 of the circulator at that same point (i.e., following attenuator A1) is +70dBm – A1. Thus, to keep the system IP3 from being adversely affected by the circulator, attenuator A1 should be no more than approxi-mately +30 dB.• A filter diplexer can be used in place of the circulator. The IP3 of the diplexer can be assumed to be greater than +100 dBm. If a diplexer is used, A3 can be omitted.• A1+A3 should be chosen so that the output power per carrier at the RAU’s output is correct for the number of carriers being transmitted. Suppose the base station transmits 36 dBm per carrier and it is desired that the RAU output be 6 dBm per carrier and the forward port gain is 0 dB. Then A1+A3=30 dB.• A2+A3 should, ideally, be at least 10 dB less than the noise figure plus the gain of the Uni-son system. For example, if the reverse port has a 0 dB gain and if there are 32 RAUs, the noise figure is approximately 22 dB. So A2+A3 should be about 10 dB. If A2+A3 is too large, the uplink coverage can be severely reduced.• Given these three equations: A1 < 30 dBA1+A3 = 30 dB (in this example)A2+A3 < 10 dB (in this example)we could choose A1=20 dB, A2=0 dB, A3=10 dBorRepeater

It attenuates the noise coming out of Unison.2. It attenuates the desired signals coming out of Unison. Setting the attenuation on the uplink is a trade-off between keeping the noise and maximum signal levels transmitted from Unison to the base station receiver low while not reducing the SNR (signal-to-noise ratio) of the path from the RAU inputs to the base station inputs. This SNR can not be better than the SNR of Unison by itself, although it can be significantly worse.For example, suppose we have a GSM Unison system consisting of one Main Hub, four Expansion Hubs, and 32 RAUs (1-4-32) with uplink NF=22 dB. (See Table 8-30 on page 8-38.) If we use 30 dB of attenuation between the Main Hub’s reverse port and the base station (which has its own noise figure of about 4 dB), the overall noise figure will be 34.3 dB (refer to the formula on page 8-36) which is 12.3 dB worse than Unison by itself. That causes a 12.3 dB reduction in the uplink coverage dis-tance. Now, if the attenuation instead is 10 dB, the cascaded noise figure is NF=22.6 dB, which implies that the uplink sensitivity is limited by Unison, a desir-able condition.Rule of ThumbA good rule of thumb is to set the uplink attenuation, A2+A3 in Figure 8-3 on page 8-48, as follows:A2+A3 ≈ Unison uplink NF + uplink gain (0 dB for reverse port) – BTS NF – 10dBand round A2 down to the nearest convenient attenuation value.
Designing a Unison Solution PRELIMINARY8-50 InterReach Unison User Guide and Reference Manual PN 8700-10620003-08.6.2.1 Uplink Attenuation Exception: CDMAIn CDMA systems, the power transmitted by the mobile is determined by the charac-teristics of both the uplink and downlink paths. The power transmitted by the mobile should be similar in open-loop control (as determined by the downlink path) as dur-ing closed-loop control (as determined by the uplink and downlink paths). In addi-tion, the mobile’s transmit power when it communicates with a base station through Unison should be similar to the power transmitted when it communicates with a base station in the outdoor network (during soft hand-off). Because of these consider-ations, you should not allow the downlink and uplink gains to vary widely.Open-loop power control:PTX = –76 dBm (for PCS) – PRXwhere PTX is the power transmitted and PRX is the power received by the mobile. If PL is the path loss (in dB) between the RAU and the mobile, and PDN is the downlink power radiated by the RAU, then PTX = –76 dBm (for PCS) – PDN + PLClosed-loop power control:PTX = noise floor + uplink NF – process gain + Eb/No + PL= –113 dBm/1.25 Mhz + NF – 19 dB + 7 dB + PLwhere Eb/No = 7 dB is a rough estimate, and NF is the cascaded noise figure of the Unison uplink, the uplink attenuation, and the base station noise figure. Equating PTX for the open-loop and closed-loop we see thatNF = 49 – PDNwhere PDN is determined by the downlink attenuation. Since PDN for Unison is about 10 dBm, we see that the cascaded noise figure is about 39 dB, which is considerably higher than that of Unison itself. This implies that we should use a fairly large attenu-ation on the uplink. This case suggests using as much attenuation on the downlink as on the uplink. The drawback of doing this is that the uplink coverage sensitivity is reduced. A link budget analysis will clarify these issues. Typically, the uplink attenu-ation between the Main Hub and the base station will be the same as, or maybe 10 dB less than, the downlink attenuation.

Since a neutral host system typically uses multiple systems in parallel, we find it best to design for the worst case system so that there will not be holes in the covered area and the economies of a single installation can be achieved. For example, as indicated Section 7.1, the 1900 MHz RF signals do not propagate throughout a building as well as the 800 MHz systems, therefore, we design to the 1900 MHz path loss formula.8.7.1 Capacity of the Unison Neutral Host SystemAs indicated in Section 2.3, “System Bandwidths,” on page 2-10, each Main Hub can support more than one sub-band of the Cellular or PCS bands. The exception to this is the iDEN Main Hub, because the SMR band is not split into sub-bands.The 800 MHz Main Hub can support both the A band and the B band simultaneously. Also, the 1800 MHz and 1900 MHz Main Hubs can support two bands each (as the frequencies currently are allo-cated).For example, a neutral host system that consists of one iDEN, one 800 MHz, and two 1900 MHz systems can support up to seven sep-arate service providers:•1 on iDEN• 2 on 800 MHz, A band and B band• 2 in each 1900 MHzRich, what’s correct for Unison?
