InterReach Fusion Wideband is an intelligent fiber optics/CATV, multi-band (frequencies) wireless networking system designed to handle both wireless voice and data communications over licensed frequencies. It provides high-quality, ubiquitous, seamless access to the wireless network in larger buildings.

Fusion Wideband provides RF characteristics designed for large public and private facilities such as campus environments, airports, shopping malls, subways, convention centers, sports venues, and so on. Fusion Wideband uses microprocessors to enable key capabilities such as software-selectable band settings, 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 Fusion Wideband system supports major wireless standards and air interface protocols in use around the world, including:

• Frequencies: 700 MHz, 800 MHz, 850 MHz, 1700 MHz, 1800 MHz, 1900 MHz, 2100 MHz, 2500 MHz, 2600 MHz.

• Voice Protocols: AMPS, TDMA, CDMA, GSM/EGSM, WCDMA, LTE, WiMAX

System Overview

• Data Protocols: CDPD, EDGE, GPRS, WCDMA, CDMA2000, 1xRTT, EV-DO, LTE, Paging, and WiMAX

The Fusion Wideband system supports three configurable bands:

• Band 1 in 60 MHz and can be configured for 700 MHz, 800 MHz, 1900 MHz, 2100 MHz, 2500 MHz, or 2600 MHz

• Band 2 in 75 MHz and can be configured for 1700 MHz, 1800 MHz, 1900 MHz, 2100 MHz, 2500 MHz, or 2600 MHz

Both bands support all protocols. Fusion Wideband remote access units (RAUs) contain combinations of Band 1,

Band 2, and Band 3 frequencies to support various world areas. These frequencies are 1800 MHz/2100 MHz for Europe, the Middle East, and Asia, or 800 MHz/850 MHz/1900 MHz for North America. Refer to Table 2-4 for a specific list of supported RAUs.

• Band 3 (only used for North America: FSN-W2-808519-1, FSN-W2-7021-1, FSN-W2-7070-1, and FSN-W2-7575-1). For example, the FSN-W2-808519-1 RAU Band 3 is a 25 MHz sub-band of the 60 MHz Band and Band 1 is an 18 MHz sub-band of the 60 MHz Band.

Key System Features

• Multi-Band, supports two or more full band frequencies for spectrum growth.

• Superior RF performance, particularly in the areas of IP3 and no ise figure.

• High downlink composite power and low uplink noise figure enables support of a large number of channels and larger coverage footprint per antenna.

• Softwar e configurable Main and Expansion Hubs allow the frequency bands to be configured in the field.

• Either single-mode or mult i-mode fibe r can be used, supporting flexible cabling alternatives (in addition to standard CATV 75 Ohm cabling). You can select the cabling type to met the resident cabling infrastructure of the facility and unique building topologies.

• Extended system “reach.” Using single-mode fiber, fiber runs can be a long as 6 kilometers (creating a total system “wingspan” of 12 kilometers). Alternatively, with multi-mode fiber, fiber runs can be as long as 500 meters.

• Standard 75 Ohm CATV cable, can be run up to 130 meters for RG-59 cable; 140 meters for RG-6; 235 meters for RG-11 using CommScope 2065V , 2279V, and 2293K cables.

• Flexib le RF configuration capabilities, including:

• System gain: – Ability to manually set gain in 1 dB steps, from 0 to 15 dB, on both down-

link and uplink.

2-2 InterReach Fusion Wideband Installation, Operation, and Reference Manual

CONFIDENTIAL D-620616-0-20 Rev F

•RAU: – RAU uplink and downlink gain can be independently attenuated 0 or 10 dB. – Uplink level control protects the system from input overload and can be

optimized for either a single operator or multiple operators/protocols.

– VSWR check on RAU reports if there is a disconnected antenna.

• Firmware Updates are downloaded (either locally or remotely) to the system

when any modifications are made to the product, including the addition of new software capabilities and services.

• OA&M capabilities, including fault isolation to the field replaceable unit, report-

ing of all fault and warning conditions, and user-friendly web browser user interface OA&M software package.

2.2 System Hardware Description

The InterReach Fusion Wideband system consists of three modular components:

System Hardware Description

• Microprocessor controlled (for alarms, monitoring, and control)

• Auto-configurable bands

• Simplex interface to RF source

• Periodically polls all downstream RAUs for system status, and automatically reports any fault or warning conditions

• 19” rack mountable Expansion Hub (connects to up to 8 Remote Access Units)

• Optical signal conversion to electrical on the downlink; electrical to optical on the uplink

• Microprocessor controlled (for alarms, monitoring, and control)

• Software configurable band (based on commands from the Main Hub)

• Supplies DC power to RAUs over CATV cable.

• Remote Access Unit (RAU)

• Converts IF signals to RF on the downlink; RF-to-IF on the uplink

• Microprocessor controlled (for alarms, monitoring, and control)

• Multi-band protocol independent, frequency specific units

The minimum configuration of a Fusion Wideband system is one Main Hub, one Expansion Hub, and one RAU (1-1-1). The maximum configuration of a system is

Help Hot Line (U.S. only): 1-800-530-9960 2-3

D-620616-0-20 Rev F CONFIDENTIAL

System Hardware Description

one Main Hub, four Expansion Hubs, and 32 RAUs (1-4-32). Multiple systems can be combined to provide larger configurations.

NOTE: The Fusion Wideband One Port Main Hub (PN: FSN-W1-MH-1P and FSN-W2-MH-1P) configuration is a cost reduced version of the Fusion Wideband Main Hub and supports only one Expansion Hub (up to 8 RAUs).

The Fusion Wideband One Port Main Hub is “software locked” to 1 port 2 fiber ports. Additional ports are disabled internally. Please do not attempt to

remove the fr ont panel fiber port plate, since doing so will void the product warranty.

2.3 System OA&M Capabilities Overview

InterReach Fusion Wideband is microprocessor controlled and contains firmware to enable much of the operations, administration, and maintenance (OA&M) functionality.

Complete alarming, down to the field replaceable unit (that is, Fusion Wideband Main Hub, Expansion Hub, and Remote Access Unit) and the cabling infrastructure, is available. All events occurring in a system, defined as a Fusion Wideband 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 basic alarm monitoring.

• Connection Methods:

• The Main Hub’s front panel RJ-45 port connects directly to a PC (for local Ethernet access).

• The Main Hub’s front panel RS-232 serial port connects directly to a modem (for remote access).

• Remote access is also available with an optional 100BASE-T LAN switch connections to the RJ-45 port.

2.3.1 System Monitoring and Reporting

Each Fusion Wideband Main Hub in the system constantly monitors itself, its Expansion Hubs, and their downstream RAUs for internal fault and warning conditions. The results of this monitoring are stored in memory and compared against new results.

When a Main or Expansion Hub detects a change in status, it reports a fault or warning alarm. Faults are also indicated locally by red status LEDs. Both faults and warnings are reported to AdminBrowser software and displayed on a PC/laptop connected to the Main Hub’s RJ-45 port. Passive antennas connected to the RAUs are not monitored automatically. Perform a System Test to retrieve status information about antennas.

Using AdminBrowser, you can install a new system or new components, change system parameters, and query system status. Figure 2-4 illustrates how the system reports its status to AdminBrowser.

2.4 System Connectivity

The double star architecture of the Fusion Wideband system, illustrated in Figure 2-5, provides excellent system scalability and reliability. The system requires only one pair of fibers for eight antenna points. This makes any system expansion, such as adding an extra antenna for additional coverage, potentially as easy as pulling an extra CATV cable.

The Fusion Wideband Main Hub (shown in Figure 3-1) distributes up to three individual (Band 1, 2, and 3) downlink RF signals from a base station, repeater, or FlexW ave Focus system to up to four Expansion Hubs, which in turn distribute the signals to up to 32 Remote Access Units. The Main Hub also combines uplink signals from the associated Expansion Hubs.

Fusion Wideband is a multi-band system. One RF source (Band 1 or RF1) goes to the 60 MHz band and the other RF source (Band 2 or RF2) goes to the 75 MHz band. Band 3 (or RF3) goes to a 25 MHz sub-band of the 60 MHz band and is functional only with the 800/850/1900, 700/AWS, 700/700 (Upper C) MIMO, and 700/700 (Lower ABC) MIMO RAU. The system installs in a 19" equipment rack and is usually co-located with the RF source in a telecommunications closet.

POWER STATUS

Upon power up, the Main Hub goes through a 20-second test to check the LED lamps. During this time, the LEDs blink through the states shown in Table 3-1, letting you visually verify that the LED lamps and the firmware are functioning properly. Upon completion of initialization, the LEDs stay in one of the first two states shown in Table 3-1.

The Main Hub automatically sends the program bands command to all connected RAUs. A mismatched band causes a fault message to be displayed in AdminBrowser and places the RAU in a disabled condition.

NOTE: Refer to Section 9.3.2 for troubleshooting using the LEDs.

NOTE: AdminBrowser should be used for troubleshooting the system.

Only use LEDs for backup or confirmation. However, if there are communication problems within the system, the LEDs may provide additional information that is not available using AdminBrowser.

5.1 RAU Overview

The Remote Access Unit (RAU) is an active transceiver that connects to an Expansion Hub using industry-standard CATV cable, which delivers RF signals, configuration information, and electrical power to the RAU.

An RAU passes converted IF to RF (Downlink) and converted RF to IF (Uplink) signals between an Expansion Hub and an attached passive antenna where the signals are transmitted to wireless devices as shown in Figure 5-1.

6.1 Overview

Designing a Fusion Wideband solution is a matter of determining coverage and capacity needs. This requires the following steps:

1. Determine the wireless service provider’ s r equir ements: Refer to Section 6.2,

“Downlink RSSI Design Goal,” on page 6-3.

The following information is typically provided by the service provid er:

• Frequency (for example, 1900 MHz)

• Band (for example, “A-F” band in the PCS spectrum)

• Protocol (for example, CDMA, GSM, 1xRTT, GPRS, and so on)

• Number of sectors and peak capacity per sector (translates to the number of RF carriers that the system will have to transmit)

• Downlink RSSI design goal (RSSI, received signal strength at the wireless handset, for example, –85 dBm)

InterReach Fusion Wideband Installation, Operation, and Reference Manual 6-1

D-620616-0-20 Rev F CONFIDENTIAL

Overview

The design goal is always a stronger signal than the mobile phone needs. It includes inherent factors which affect performance.

• RF source (base station or bidirectional amplifier or repeater), type of equipment if possible.

2. Determine the downlink power per carrier from the RF source through the

DAS: Refer to Section 6.3, “Maximum Output Power per Carrier,” on page 6-4.

The maximum power per carrier is a function of modulation type, the number of RF carriers, signal quality issues, regulatory emissions requirements, and Fusion Wideband’s RF performance. Power per carrier decreases as the number of carriers increases.

3. Develop an RF link budget: Refer to Section 6.5, “Estimating RF Coverage,”

on page 6-16.

Knowing both the power per carrier and RSSI design goal, you can develop an RF downlink link budget which estimates the allowable path loss from an RAU’s antenna to the wireless handset.

allowable path loss = power per carrier + antenna gain – design goal

Satisfactory performance can be expected as long as path loss is below this level.

4. Determine the in-building envir onment: Refer to Section 6.5, “Estimating RF

Coverage,” on page 6-16.

• Determine which areas of the building require coverage (entire building, public areas, parking levels, and so on.)

• Obtain floor plans to determine floor space of building and the wall layout of the proposed areas to be covered. Floor plans are also useful when you are selecting antenna locations.

• If possible, determine the building’s construction materials (sheetrock, metal, concrete, and so on.)

• Determine the type of environment: – Open layout (for example, a convention center) – Dense, close walls (for example, a hospital) – Mixed use (for example, an office building with hard wall offices and cubi-

cles)

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: Refer to Section 6.5, “Estimat ing RF Coverage,” on page 6-16.

Use the path loss slope (PLS), which gives a value to the RF propagation characteristics within the building, to convert the RF link budget into an estimate of the coverage distance per antenna. This helps establish the quantities of Fusion Wi deband equipment you need. The actual path loss slope that corresponds to the specific 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: Refer to

Section 6.8, “Connecting a Main Hub to a Base Station,” on page 6-37.

Once you know the quantities of Fusion Wideband equipment to be used, you can determine the accessories (combiners/dividers, surge suppressors, repeaters, attenuators, circulators, and so on.) required to connect the system to the base station.

The individual elements that must be considered in designing a Fusion Wideband solution are explained in the following sections.

NOTE: Access the TE Customer Portal at http://www.te.com/adc for on-line dimensioning and design tools.

6.2 Downlink RSSI Design Goal

Wireless service providers t ypically provide a minimum downlink signal level and an associated confidence factor when specifying coverage requirements. These two figures of merit are a function of wireless handset sensitivity and margins for fading and body loss. Wireless handset sensitivity is the weakest signal that the handset can process reliably and is a combination of the thermal noise in the channel, noise figure of the handset receiver front end and minimum required SNR. Fade margins for multipath fading (fast or small-scale) and log-normal shadow fading (slow or large-scale) are determined by the desired confidence factor, and other factors. Downlink RSSI design goal calculations for the GSM protocol are shown below for a 95% area coverage confidence factor.

D-620616-0-20 Rev F CONFIDENTIAL

Maximum Output Power per Carrier

Downlink design goals on the order of –85 dBm are typical for protocols, such as GSM. Wireless service providers may choose a higher level to ensure that in-building signal dominates any macro signal that may be leaking into the building.

6.3 Maximum Output Power per Carrier

The following tables show the recommended maximum power per carrier out of the RAU 50 Ohm Type-N connector for different frequencies, protocols, and numbers of carriers. These maximum levels are dictated by RF signal quality and regulatory emissions issues. In general, as the number of RF carrier increases, the maximum power per carrier decreases. If these levels are exceeded, signal quality will be degraded and/or regulator requirements will be violated. The maximum input power to the 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 gain of each RAU can be attenuated 0 or 10 dB.

When connecting a Hub to a base station or repeater, attenuation on the downlink is typically required to avoid exceeding Fusion Wideband’s maximum output power recommendations.

WARNING: Exceeding the maximum input power may cause permanent damage to the Hub. Do not exceed the maximum composite input power of 1W (+30 dBm) to the Hub at any time.

NOTE: These specifications are for downlink power at the RAU output (excluding antenna).

Designing for Capacity Growth

Fusion Wideband systems are deployed to enhance in-building coverage and/or to off-load capacity from a macro cell site. In many instances, subscriber usage increases with time and the wireless provider responds by increasing the load on the installed Fusion Wideband system. For example, the initial deployment might only require two RF carriers, but four RF carriers may be needed in the future based on capacity growth forecasts. There are two options for dealing with this scenario:

1. Design the initial coverage with a maximum power per carrier for four RF carri-

ers. This will likely result in additional RAUs.

2. Design the initial coverage for two RF carriers, but reserve RAU ports on the Hub

for future use. These ports can be used to fill potential coverage holes once the power per carrier is lowered to accommodate the two additional carriers.

6.4 System Gain

The system gain of the Fusion Wideband defaults to 0 dB or can be set up to 15 dB in 1 dB increments. In addition, uplink and downlink gains of each RAU can be independently attenuated by 0 or 10 dB usin g AdminBrowser.

The recommended maximum lengths of CATV cable are as follows:

• For RG-59 cable 130 meters for CommScope PN 2065V.

• For RG-6 cable 140 meters for CommScope PN 2279V.

• For RG-11 cable 235 meters for CommScope PN 2293K. If the maximum distance is not required, then copper-clad over steel center -conductor

cable may be use to reduce cable costs. If the CATV cable is longer than the recommended distance per cable type, the gain

of the system will decrease, as shown in Table 6-13.

6.5 Estimating RF Coverage

The maximum output power per carrier (based on the number and type of RF carriers being transmitted) and the minimum acceptable received power at the wireless device (that is, the RSSI design goal) essentially establish the RF downlink budget and, consequently, the maximum allowable path loss (APL) between the RAU’s antenna and the wireless device. Since in-building systems, such as the Fusion Wideband, are generally downlink-limited, this approach is applicable in the majority of deployments.

6.5.3 Examples of Design Estimates

Example Design Estimate for an 1900 MHz CDMA Application

1. Design goals:

• PCS (1920 MHz = average of the lowest uplink and the highest downlink frequency in 1900 MHz PCS band)

• CDMA provider

• 8 CDMA carriers in the system

• –85 dBm design goal (to 95% of the building) — the mini mum received power at the wireless device

• Base station with simplex RF connections

2. Power Per Carrier: The tables in Section 6.3, “Maximum Output Power per Car-

rier,” on page 6-4 provide maximum power per carrier information. The 1900 MHz CDMA table indicates that Fusion Wideband can support eight 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. Building information:

• 16 floor building with 9,290 sq. meters (100,000 sq. ft.) per floor; total 148,640 sq. meters (1,600,000 sq. ft.).

• Walls are sheetrock construction, suspend ed ceiling tiles.

• Antennas used are omni-directional, ceiling mounted.

• Standard office environment, 80% hard wall offices and 20% cubicles.

4. Link Budget: In this example, a design goal of –85 d Bm is used. Suppose 3 dBi

omni-directional antennas are used in the design. Then, the maximum RF propagation loss should be no more than 94.5 dB (6.5 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 signal 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, refer to Section 6.6 on page 6-24.

5. Path Loss Slope: For a rough estimate, Ta ble 6-17, “Estimated Path Loss Slope for

Different In-Building Environments” o n page 6-18, shows that a building with 80% hard wall offices and 20% cubicles, at 1920 MHz, has an approxi mate p ath loss slope (PLS) of 38.1. Given the RF link budget of 94.5 dB, the distance of coverage from each RAU will be 30.2 meters (99 ft). This corresponds to a coverage area of 2,868 sq. meters (30,854 sq. ft.) per RAU (refer to Secti o n 6 . 5 . 1 for detail s on path loss estimation). For this case we assumed a circular radiation patt ern, thoug h the actual area covered depends up on the pattern of the antenna and the obstru ctions in the facility .

Estimating RF Coverage

6. Equipment Required: Since you know the building size, you can now estimate

the Fusion Wideband equipment quantities needed. Before you test any RF levels in the building, you can estimate that four antennas per level will be needed. This assumes no propagation between floors. If there is propagation, you may not need antennas on every floor.

a. 4 antennas per floor × 16 floors = 64 RAUs b. 64 RAUs ÷ 8 (maximum 8 RAUs per Expansion Hub) = 8 Expansion Hubs c. 8 Expansion Hubs ÷ 4 (maximum 4 Expansion Hubs per Main Hub) = 2 Main

Hubs

Check that the fiber and CATV cable distances are as recommended. If the distances differ, use the tables in Section 6.4, “System Gain,” on page 6-14 to determine 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, additional 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 Fusion Wideband equipment quantities required for the building. The site survey measures the RF losses within the building to determine the actual PLS, used in the final path loss formula to determine the actual requirements of the Fusion Wideband system.

Link Budget Analysis

6.6 Link Budget Analysis

A 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 explained in Section 6.3. 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.

NOTE: Visit the TE customer portal at http://www.te.com/adc for the on-line Link Budget Tool.

6.6.1 Elements of a Link Budget for Narrowband Standards

The link budget represents a typical calculation that might be used to determine how much path loss can be afforded in a Fusion Wideband design. This link budget analyzes both the downlink and uplink paths. For most configuratio ns, 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 6.5.1.

Table 6-25 provides link budget considerations for narrowband systems.

Table 6-25 Link Budget Considerations for Narrowband Systems

Consideration Description

BTS Transmit Power The power per carrier transmitted from the base station output Attenuation between

BTS and Fusion Wideband

This 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 6.3. 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 Fusion Wideband noise figure minus the attenuation is at least 10 dB higher than the BTS

noise figure, the system noise figure is approximately that of Fusion Wideband alone. Refer to Section 6.8 for ways to independently set the uplink and downlink attenuations between the base station and Fusion Wideband.

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 ef fect ive 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).

Fusion Wideband Noise Figure

This is Fusion Wideband’s uplink noise figure, which varies depending on the number of Expansion Hubs and RAUs, and the frequency band. Fusion Wideband’s uplink noise figure is specified for a 1-1-8 configuration. Thus, the noise figure for a Fusion Wideband system (or multiple systems whose uplink ports are power combined) is NF(1-1-8) + 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.

Thermal 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

The maximum power the mobile can transmit (power transmitte d at highest power level setting).

Power Multipath Fade

Margin

This 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 diffraction. Signals arriving from multiple paths add constructively or destructively. This ma rgin accounts for the possibility of destructive multipath interference. In RF site surveys the effect s of multipath fading are typically not accounted for because such fading is averaged out over power level samples taken over many locations.

accounted for since it is characterized by relatively slow changes in power level. Body Loss This accounts for RF attenuation caused by the user’s head and body. Minimum Received

Signal Level

This 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.

6.6.3 Elements of a Link Budget for CDMA Standards

A CDMA link budget is slightly more complicated because you must consider the spread spectrum nature of CDMA. 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 com po site 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. Table 6-28 shows an example.

Table 6-28 Distribution of Power within a CDMA Signal

Link Budget Analysis

Channel Walsh Code Number Relative Power Level

Pilot 0 20% –7.0 dB Sync 32 5% –13.3 dB Primary Paging 1 19% –7.3 dB Traffic 8–31, 33–63 9% (per traffic channel) –10.3 dB

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 channels 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-handoff 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.

It’s a good idea to keep –12 dB <  Table 6-29 provides link budget considerations for CDMA systems.

Table 6-29 Additional Link Budget Considerations for CDMA

Consideration Description

Multipath Fade Margin

Power per carrier, downlink

Information Rate This is simply

The 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 mu ltipat hs’ signa ls can be resolved and pro cessed independently by the base station’s rake receiver. A CDMA signal traveling through 163 meters of MMF cable is delayed by approximately one chip.

This depends on how many channels are active. For example, the signal is 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 (representing 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 determine how hard the Fusion Wideband system is being driven.

The total power for a fully-loaded CDMA signal is given by (approximately):

total power = = voice channel power + 10 dB

Table 6-29 Additional Link Budget Considerations for CDMA (continued)

Consideration Description

Process 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 1

= 10log10(1.25 MHz / 14.4 Kbps) = 19 dB rate set 2

Note that the process gain can also be expressed as 10log

(CDMA bandwidth) minus the information

rate.

Eb/No This is the energy-per-bit divided by the received noise and interfe rence. 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 E

is lower and the mul-

b/No

tipath 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:

= NF + Eb/No + thermal noise in a 1.25 MHz band – P

sensitivity

= NF + E

– 113 (dBm/1.25 MHz) – P

b/No

Noise Rise On the uplink, the noise floor is determined not only by the Fusion Wideband system, but also by the num-

ber 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 = 10log

(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.

Other CDMA Issues

• Never combine multiple sectors (more than one CDMA signal at the same frequency) into a Fusion Wideband system. 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 important 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.
