Downlink Path: The Main Hub receives up to 3 individual (Band1, 2, or 3) downlink RF signals from a base station, repeater,

or FlexWave Focus system using 50 Ohm coaxial cable. It converts the signals to IF then to optical and sends them to up to

four Expansion Hubs using fiber optic cable.

The Main Hub also sends OA&M communication to the Expansion Hubs using the fiber optic cable. The Expansion Hubs,

in turn, communicate the OA&M information to the RAUs using CATV cable.

Uplink Path: The Main Hub receives uplink optical signals from up to four Expansion Hubs using fiber optic cables. It converts

the signals to IF then to RF and sends them to the respective Band1, 2, or 3 base station, repeater, or FlexWave Focus system

using 50 Ohm coaxial cable.

The Main Hub also receives status information from the Expansion Hubs and all RAUs using the fiber optic cable.

Downlink Path: The Expansion Hub receives downlink (Band 1, 2, and 3) optical signals from the Main Hub using fiber optic

cable. It converts the signals to electrical and sends them to up to eight Remote Access Units (RAUs) using CATV cables. The

Expansion Hub also receives configuration information from the Main Hub using the fiber optic cable and relays it to the RAUs

using CATV cable.

Uplink Path: The Expansion Hub receives uplink (Band 1, 2, and 3) IF signals from up to eight RAUs using CATV cables. It

converts the signals to optical and sends them to a Main Hub using fiber optic cable.

The Expansion Hub also receives RAU status information using CATV cable and sends it and its own status information to the

Main Hub using the fiber optic cable.

Downlink Path: The RAU receives downlink IF signals from a Fusion Wideband Hub using 75 Ohm CATV cable. It converts

the signals to RF and sends them to a passive RF antenna using 50 Ohm coaxial cable. Also, the RAU receives configuration

information from the Fusion Wideband Hub using the 75 Ohm CATV cable.

Uplink Path: The RAU receives uplink RF signals from a passive RF antenna using 50 Ohm coaxial cable. It converts the

signals to IF and sends them to a Fusion Wideband Hub using 75 Ohm CATV cable. Also, the RAU sends its status information

to the Fusion Wideband Hub using CATV cable.

The RAU receives 54VDC power from the Fusion Wideband Hub port through the 75 Ohm CATV cable center pin.

OVERVIEW

DesigningaFusionWidebandsolutionisamatterofdeterminingcoverageandcapacityneeds.

Thisrequiresthefollowingsteps:

1Determinethewirelessserviceprovider’srequirements;referto“DownlinkRSSI

DesignGoal”onpage64.

Thefollowinginformationistypicallyprovidedbytheserviceprovider:

•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)

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.

2DeterminethedownlinkpowerpercarrierfromtheRFsourcethroughtheDAS;refer

to“MaximumOutputPowerperCarrier”onpage65.

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.

3DevelopanRFlinkbudget;referto“EstimatingRFCoverage”onpage82.

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

•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cubicles)

5Determine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

“EstimatingRFCoverage”onpage82.

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Wideband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calibratedtoneforafixedantennaandmakingmeasurementswithamobile

antennathroughouttheareasurroundingthetransmitter.

6Determinetheitemsrequiredtoconnecttothebasestation;referto“Connectinga

MainHubtoaBaseStation”onpage101.

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.

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 “Maximum Output Power per Carrier” on page 65.

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 “Connecting a

Main Hub to a Base Station” on page 101 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 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 effective

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 Power The maximum power the mobile can transmit (power transmitted at highest power level setting).

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 margin accounts for the

possibility of destructive multipath interference. In RF site surveys the effects of multipath fading are

typically not accounted for because such fading is averaged out over power level samples taken over

many locations.

Log-normal Fade 

Margin

This 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, the effects of shadowing are partially 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 coverage

if the signal level is, on average, above this level over 95% of the area covered, for example.

Consideration Description

Multipath Fade

Margin

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 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 is delayed by approximately one

chip.

Power per carrier,

downlink

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 + 13 dB + 10log10 (50%)

= voice channel power + 10 dB

Information Rate This is simply

10log10(9.6 Kbps) = 40 dB for rate set 1

10log10(14.4 Kbps) = 42 dB for rate set 2

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

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

Note that the process gain can also be expressed as 10log10 (CDMA bandwidth) minus the information rate.

Eb/No This is the energy-per-bit divided by the received noise and interference. It’s the CDMA equivalent of

signal-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 is 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) – PG

mobilewillresultinsoft‐handoff.Soft‐handoffdecreasestheoverallnetworkcapacityby

allocatingmultiplechannelresourcestoasinglemobilephone.

Noise Rise On the uplink, the noise floor is determined not only by the Fusion Wideband 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.
