Maximum Output Power per Carrier Downlink design goals on the order of –85 dBm are typical for protocols, such as GSM and iDEN. 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.

Estimating RF Coverage 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.
Estimating RF Coverage 6.5.1 Path Loss Equation In-building path loss obeys the distance power law1 in equation (2): PL = 20log10(4πd0f/c) + 10nlog10(d/d0) + Χs (2) where: • PL is the path loss at a distance, d, from the antenna • d = the distance expressed in meters • d0 = free-space path loss distance in meters • f = the operating frequency in Hertz. • c = the speed of light in a vacuum (3.0 × 108 m/sec).
Estimating RF Coverage 6.5.2 RAU Coverage Distance Use equations (1) and (2), on pages 6-14 and 6-15, respectively, to estimate the distance from the antenna to where the RF signal decreases to the minimum acceptable level at the wireless device. With d0 set to one meter and path loss slope (PLS) defined as 10n, Equation (2) can be simplified to: PL(d) = 20log10(4πf/c) + PLS·log10(d) (3) Table 6-10 gives the value of the first term of Equation (3) (that is., (20log10(4πf/c)) for various frequency bands.
Estimating RF Coverage Table 6-11 shows estimated PLS for various environments that have different “clutter” (that is, objects that attenuate the RF signals, such as walls, partitions, stairwells, equipment racks, and so.).

Estimating RF Coverage 6.5.3 Examples of Design Estimates Example Design Estimate for an 850 MHz TDMA Application 1. Design goals: • Cellular (859 MHz = average of the lowest uplink and the highest downlink frequency in 800 MHz Cellular band) • TDMA provider • 12 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 connections 2. Power Per Carrier: The tables in Section 6.
Estimating RF Coverage Equipment Required: Since you know the building size, you can now estimate the Fusion equipment quantities that will be needed. Before any RF levels are tested in the building, you can estimate that two 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. 2 antennas per floor × 8 floors = 16 RAUs b. 16 RAUs ÷ 8 (maximum 8 RAUs per Expansion Hub) = 2 Expansion Hubs c.
Estimating RF Coverage 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 minimum received power at the wireless device • Base station with simplex RF connections 2. Power Per Carrier: The tables in Section 6.
Estimating RF Coverage 6. Equipment Required: Since you know the building size, you can now estimate the Fusion 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.
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.
Link Budget Analysis Table 6-19 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 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.
Link Budget Analysis Table 6-19 Link Budget Considerations for Narrowband Systems (continued) Consideration Description 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.

Link Budget Analysis 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.
Link Budget Analysis PTX + 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 6-23 on page 6-31).
Link Budget Analysis Table 6-23 Additional Link Budget Considerations for CDMA (continued) Consideration Description 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.

Optical Power Budget 6.7 Optical Power Budget Fusion uses SC/APC connectors. The connector losses associated with mating to these connectors is accounted for in the design and should not be included as elements of the optical power budget. The reason is that when the optical power budget is defined, measurements are taken with these connectors in place. The Fusion optical power budget for both multi-mode and single-mode fiber cable is 3.0 dB (optical).
Connecting a Main Hub to a Base Station 6.8 Connecting a Main Hub to a Base Station The Fusion system supports up to three RF sources: one for Band 1, one for Band 2, and one for Band 3. This section explains how each band can be connected to its associated base station. Each Fusion Main Hub band has separate system gain parameters. For example, Band 1 can be set for +5 dB of downlink system gain while Band 2 can have +15 dB of downlink system gain.
Connecting a Main Hub to a Base Station inputs. This SNR can not be better than the SNR of Fusion by itself, although it can be significantly worse. A good rule of thumb is to set the uplink attenuation such that the noise level out of Fusion is within 10 dB of the base station’s sensitivity. 6.8.2 RAU Attenuation and ALC The RAU attenuation and ALC are set using the AdminBrowser Edit Unit Properties screen. Embedded within the uplink RF front-end of each Fusion RAU band is an ALC circuit.
Connecting a Main Hub to a Base Station Figure 6-2 ALC Operation Input Signal Level Activation Level -30dBm Output Signal Level 4 Release Level -45dBm 3 1 2 Attack Phase Hold Phase 5 Release Phase Time 6.8.2.1 Using the RAU 10 dB Attenuation Setting Each RAU band can, independently of the other RAUs in a system, have its uplink or downlink gain attenuated by 10dB in 1dB steps for each RAU band (1, 2, or 3).
Connecting a Main Hub to a Base Station 6.8.2.2 Using the Uplink ALC Setting Uplink automatic level control (UL ALC) circuitry for each band within the RAU provides automatic level control on high-power signals in the uplink path. This functionality is required to prevent RF signal compression caused by a single or multiple wireless devices in very close proximity to the RAU band. Compression causes signal degradation and, ultimately, dropped calls and data errors, and should be prevented.

Fusion Installation Procedures Upon power-up, the LEDs blinks for five seconds as a visual check that they are functioning. After the five-second test: LED states during power on will vary, depending on whether Expansion Hubs are connected. Refer to Table 7-5 for possible combinations. Table 7-5 During Installation Power On 1. Main Hub power is On with no Expansion Hubs connected.
Fusion Installation Procedures 7.4.2 Installing Expansion Hubs The Expansion Hub (2U high) can be installed in a standard 19 in. (483 mm) equipment rack or in a wall-mountable equipment rack that is available from LGC Wireless. Allow a clearance of 76 mm (3 in.) front and rear and 51 mm (2 in.) sides for air circulation. No top and bottom clearance is required. CAUTION: Install Expansion Hubs in indoor locations only.
Fusion Installation Procedures Installing an Expansion Hub Using the 12” Wall-Mounted Rack Considerations: • The rack (PN4712) is 305 mm (12 in.) deep. The Expansion Hub is 381 mm (15 in.) deep. You must move the rack mounting brackets on the Expansion Hub, as shown in Figure 7-16) to the center mounting position to allow for the 76 mm (3 in.) rear clearance that is required. • The maximum weight the rack can hold is 22.5 kg (50 lbs).
Fusion Installation Procedures Installing a Fusion Expansion Hub Directly to the Wall To install the Hub directly to the wall: 1. Pre-install 3/4” plywood to the wall. 2. Mount both of the rack mounting brackets using #10-32 machine screws (refer to illustration Figure 7-17). 3. Attach the Hub to the wall so the mounting brackets are orientated at the top and bottom of the wall mounted hub. (Refer to Figure 7-18.
Fusion Installation Procedures Figure 7-18 Installing Directly to the Wall NOTE: Leave the dust caps on the fiber ports until you are ready to connect the fiber optic cables. Installing an Optional Cable Manager in the Rack • Using the screws provided, fasten the cable manager to the rack, immediately above or below the Expansion Hub. Powering On the Expansion Hub 1. 7-28 CONFIDENTIAL Connect the AC or DC power as explained in “Making Power Connections” on page 7-18.
Fusion Installation Procedures 2. Turn on the power to the Expansion Hub and check that all the LED lamps are functioning properly. Upon power-up, the LEDs blinks for five seconds as a visual check that they are functioning. After the five-second test: • The POWER and UL STATUS LEDs should be green. – If the uplink fiber is not connected, the UL STATUS LED turns red indicating that there is no communication with the Main Hub. • The E-HUB STATUS and DL STATUS LEDs should be red.
Fusion Installation Procedures If the UL STATUS and E-HUB STATUS LEDs do not turn green/green, check the Main Hub LEDs. Refer to page 7-24, item 2 in Table 7-5. If the fiber jumper is color-coded (for example, “blue” or “red”): 1. Connect “red” to DOWNLINK on Expansion Hub. The DL STATUS LED should turn green as soon as you connect the fiber. If it does not, there is a downlink problem. Make sure you are connecting the correct cable to the port. 2. Connect “blue” to UPLINK on Expansion Hub.
Fusion Installation Procedures Troubleshooting Expansion Hub LEDs During Installation • All Expansion Hub PORT LEDs with RAUs connected should indicate Green/Red. This indicates that the RAU is powered on and communication has been established. • The Expansion Hub UL STATUS LED should be Green. Table 7-6 Troubleshooting Expansion Hub LEDs During Installation During Installation LED State Action Impact 1.
Fusion Installation Procedures 7.4.3 Installing RAUs CAUTION: Install RAUs in indoor locations only. Do not connect an antenna that is installed in an outdoor location to an RAU. For outdoor installations, a protective enclosure is required. Installing RAUs Mount all RAUs in the locations marked on the floor plans. Considerations: • Install 800 iDEN and 850/1900 MHz RAUs so that their antennas will be separated by enough space to reduce signal interference between the 800 and 850 bands.
Fusion Installation Procedures these situations is to provide sufficient isolation by physically separating the interfering transmitters and receivers. iDEN occupies spectrum at both 800 MHz and 900 MHz (Tx:806–825/Rx:851–870 and Tx:896–901/Rx:935–940), while the Cellular A and B carriers share a single 850 MHz block (Tx:869–894/Rx:824–849).
Fusion Installation Procedures cause the 850 Cellular uplink automatic level control (ALC) circuitry in the RAU to engage and thereby reduce uplink gain. To prevent either of these conditions, use the following guidelines: • In-band 800 iDEN intermodulation products < -90dBm • Lower frequency 800 iDEN signals < –30dBm for Fusion Given a typical DAS configuration (4 iDEN carriers, omni-directional antennas, line of sight), these guidelines translate to an antenna spacing (d1) of 6 – 9 meters.
Fusion Installation Procedures • Fusion Main Hub port number being used • RAU identifier • Carrier (for multiple operator systems) To connect the CATV cable: 1. Connect the CATV cables to the F female port on the RAU according to the label on the cable. Power is supplied by the Fusion Main Hub over the CATV cable conductors. Upon power up, the LEDs will blink for two seconds as a visual check that they are functioning.
Fusion Installation Procedures 7.4.3.2 Installing RAUs in a Multiple Operator System When installing both iDEN and Cellular systems in parallel, either as dual-band or multiple operator systems, you must take special provision to assure that the individual RAUs do not interfere with each other. The 850/1900 MHz and 800/900/1900 MHz RAU’s antennas must be separated by at least 8 meters (26 feet) to assure that the iDEN downlink signals do not interfere with the Cellular uplink signals. 7.4.

Splicing Fiber Optic Cable 7.5 Splicing Fiber Optic Cable The fiber cable must have SC/APC connectors for the entire run. If it does not, you can splice a pigtail, which has SC/APC connectors, to the fiber cable. LGC offers two pigtails: one for single-mode fiber (PN 4013SCAPC-3) and one for multi-mode fiber (PN 4012SCAPC-3). LGC Wireless recommends fusion splices because they have the lowest splice loss and return loss.
Splicing Fiber Optic Cable 12. Return fiber splice to the splice tray, store the sleeve in a splice holder within the tray, and store excess cable length in accordance with the tray manufacture’s directions. After successfully testing the fiber, plug the SC/APC pigtail into the proper optical port on the Hub. To fusion splice the fiber optic cable to the SC/APC pigtail: Option B 1. Secure both the fiber cable and the SC/APC pigtail in a splice tray portion of a fiber distribution panel. 2.
