Downlink Path: The Main Hub receives up to 3 individual (Band1, 2, or 3) downlink RF signals from a base sta�on, repeater, or FlexWave Focus system using 50 Ohm coaxial cable. It converts the signals to IF then to op�cal and sends them to up to four Expansion Hubs using fiber op�c cable.

The Main Hub also sends OA&M communica�on to the Expansion Hubs using the fiber op�c cable. The Expansion Hubs, in turn, communicate the OA&M informa�on to the RAUs using CATV cable.

Uplink Path: The Main Hub receives uplink op�cal signals from up to four Expansion Hubs using fiber op�c cables. It converts the signals to IF then to RF and sends them to the respec�ve Band1, 2, or 3 base sta�on, repeater, or FlexWave Focus system using 50 Ohm coaxial cable.

The Main Hub also receives status informa�on from the Expansion Hubs and all RAUs using the fiber op�c cable.

Ref # Description

1 One port LED and connector pair for eight ports, labeled Port n, where n = 1 - 8

• One port LED per type F connector port for link status and downstream RAU status (8 pair total). See "Unit Status and DL/UL STATUS LEDs” on page 52.

• Eight CATV cable, type F connectors for the CATV cables used to transmit and receive signals to and from RAUs. Use only 75 ohm type F connectors on the CATV cable. The CATV cable also delivers DC electrical power to the RAUs. The Expansion Hub’s DC voltage output is 54V DC nominal. A current limiting circuit protects the Hub if any port draws excessive power.

NOTE: For system performance, it is important to use only low loss solid copper center conductor CATV cable with quality type F connectors that use captive centerpin connectors. Refer to "Cables and Connectors” on page 189 for approved cables and connectors.

• For information on the Port LEDs, see "Port STATUS LEDs” on page 54.2 LEDS

(Left to right, top to bottom)

POWER LED Indicates if the Expansion Hub is turned on or off and the status of the various power supplies.

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 could cause permanent damage to the Main Hub.

Table 6-14. 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 system

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 69. 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 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 alone. Refer to "Connecting a Main Hub to a Base Station” on page 92 for ways to independently set the uplink and downlink attenuations between the Base Station and Fusion.

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 Noise Figure This is Fusion’s uplink noise figure, which varies depending on the number of Expansion Hubs and RAUs, and the frequency band. Fusion’s uplink noise figure is specified for a 1-1-8 configuration. Thus, the noise figure for a Fusion 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. On the inside of 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.

Table 6-18. Additional Link Budget Considerations for CDMA


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 despreading) 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 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 110log10(14.4 Kbps) = 42 dB for rate set 2

Process Gain The process of despreading 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 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



Other CDMA IssuesOtherCDMAissuesareasfollows:• Nevercombinemultiplesectors(morethanoneCDMAsignalatthesamefrequency)intoaFusionsystem.ThecombinedCDMAsignalswillinterferewitheachother.• Trytominimizeoverlapbetweenin-buildingcoverageareasthatutilizedifferentsectors,aswellasin-buildingcoverageandoutdoorcoverageareas.Thisisimportantbecauseanyareainwhichmorethanonedominantpilotsignal(atthesamefrequency)ismeasuredbythemobilewillresultinsoft-handoff.Soft-handoffdecreasestheoverallnetworkcapacitybyallocatingmultiplechannelresourcestoasinglemobilephone.

Noise Rise On the uplink, the noise floor is determined not only by the Fusionsystem, but also by the number of mobiles that are transmitting. This is because when the Base Station attempts to despread 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.

DuringNormal Operation

Main Hub Port LEDs

State Impact Action

Expansion Hub Not Connected

Port Red The Expansion Hub was previously connected, but it is not currently connected; the Expansion Hub uplink cable disconnected.AdminBrowser clears all disconnects caused by installation as part of the clean-up process. After installation, power cycle the Main Hub or use the AdminBrowser Clear All Disconnect Status command.Changes the Main Hub’s port LEDs to Off/Off.

If the Expansion Hub was disconnected accidentally, re-connect the cables. The LEDs should change to Green/Red, and then Green/Green, after 20 seconds (if the Main Hub band has been programmed).When the Expansion Hub is to be removed from service permanently, use the AdminBrowser Clear All Disconnect Status command to clear all disconnect states.

Expansion Hub Connected

Port Flashing Red (60 ppm)

Lost communication with Expansion Hub; could be a problem with the Expansion Hub or the fiber cable.The Expansion Hub communication problems delay Main Hub’s response to AdminBrowser commands, resulting in command time-outs. You can initially disconnect the offending Expansion Hub to obtain status from the rest of the system, then reconnect the Expansion Hub and resolve the communication problem.

Use AdminBrowser to determine the exact cause of the Main Hub’s faults.

Port Red Unit may have degraded performance or go off-line, which is dependent on the fault condition.

The Expansion Hub or connected RAU reports a fault condition; use AdminBrowser to determine the exact cause of the corresponding unit’s faults.

Table 9-2. Troubleshooting MAIN HUB STATUS LEDs During Normal Operation


MAIN HUB STATUS LEDs

State Impact Action

At Any Time Main Hub Status Red Internal Main Hub fault. Use AdminBrowser to determine the exact cause of the fault.Power cycle one time. If the fault remains, replace the Main Hub.

The Main Hub and all downstream units are off-line.

Use AdminBrowser to check if the Main Hub is commanded Out-of-Service (every Expansion Hub port STATUS LED will be red as well). A power cycle will not clear a commanded Out-of-Service, you must use AdminBrowser to clear this state.

Main Hub Status Flashing Red (60ppm)

Signal compression. Reduce input signal power.

At Any Time Power Red One or more power supplies are out of specification.

Port Red Lost communications with the RAU. The RAU could have powered down due to over current; cable could have been damaged.

Disconnect/reconnect the CATV cable to force power-on reset to the RAU. If the PORT LEDs remain red, use AdminBrowser to check for the exact cause of the Expansion Hub faults.


Depends on the fault condition. The RAU reports a fault condition; use AdminBrowser to check for the exact cause of the Expansion Hub and RAU faults.


The Expansion Hub reports no connection with the RAU, cable shorts, or a current port trap condition.

The Expansion Hub is not communicating with the RAU; the Expansion Hub is at fault. The cable could have been damaged. The cable leads may be shorted.

Table 9-4. Troubleshooting Expansion Hub STATUSLEDs During Normal Operation


Expansion Hub STATUSLEDs

State Impact Action

At Any Time UL STATUS Red No communications between the Main Hub and the Expansion Hub.Uplink laser failure.

Check uplink fiber for optical loss.Power cycle Expansion Hub one time to check uplink laser.

DL STATUS Red No communications with the Main Hub. Check the downlink fiber for optical loss

E-H STATUS Red Internal Expansion Hub fault (including either of the above UL STATUS or DL STATUS states).

If either the UL STATUS or the DL STATUS are also red, see above.Cycle power on the Expansion Hub. If fault remains, replace the Expansion Hub.
