4 Configuration and combining options

This chapter describes the combining options supported in Nokia UltraSite BTS

and links them with the cable kits that come with the units in the BTS delivery

package. Some common cabinet configurations are also illustrated.

Caution

Nokia requires that only properly trained and authorised personnel perform

installation, cabling, commissioning, and maintenance operations on any Nokia

BTS.

Combining options

Nokia UltraSite EDGE BTS supports various combining options. You can

configure Nokia UltraSite EDGE BTS in the following ways:

. Combining Bypass: no signal combining is used.

. Wideband Combining (WBC)

- 2-Way WBC Signals from two TSxx units are combined into one

antenna using one WCxA unit.

- 4-Way WBC Signals from four TSxx units are combined into one

antenna using two parallel WCxA units in series and a single WCxA

unit.

. Remote Tune Combining (RTC)

- Signals from six TSxx units combine into one antenna with one

RTxx unit.

- Signals from twelve TSxx units combine into two antennas (a

separate antenna for RX diversity is unnecessary). Two RTxx units

are needed.

. Dual Band Combining (GSM 800/1900 or 900/1800 in the same cabinet)



25 (64)

Configuration and combining options



- Use any WBC or RTC combining option within each band.

- DU2x combines RX/TX signals into one antenna (optional).

.

Horizontal Sectoring (combining signals from different cabinets)

- Use any WBC or RTC combining option.

Cabinet configurations

To accomplish these combining options, Nokia UltraSite EDGE BTS supports

various cabinet configurations.

Nokia UltraSite EDGE MIDI BTS supports the same basic configurations as

Nokia UltraSite EDGE BTS, but has practical limitations due to differences in the

number of TSxx units supported per cabinet.

During Commissioning of configurations that include an Outdoor UltraSite

EDGE MIDI BTS, full size Outdoor UltraSite EDGE BTS should be selected in

the Hardware Configurator to ensure proper function of environmental controls.

The remainder of the chapter presents examples of various cabinet combining

configurations, including:

. 1+1+1, DVxx, Combining bypass, IBBU

. 2+2+2, DVxx, Combining bypass, IBBU

4.6 WCDMA cable configurations and transmissioncable installation

4.6.1 Cable sets

The cable sets are delivered with the units when the configuration is ordered from

the factory. All cables are identified by the cable code and the cable label.

During commissioning, the code and label information can be stored into a file in

the BTS.

4.6.2 1+1+1 carrier configuration

WCDMA antenna cables in 1+1+1 configuration

Figure 35 shows the WCDMA antenna cable connections to WAF units in 1+1+1

configuration.

To install the WCDMA antenna cables:

1. Connect the WCDMA antenna cables to the WAF unit connectors as

shown in Figure 35.

2. Tighten each antenna cable to 25 Nm after installing it.






Figure 35. Antenna cables in 1+1+1 configuration

TX cables in 1+1+1 configuration

Figure 36 shows the TX cable connections between the WAF and WMP units in 1

4.6.3 Transmission cables

Nokia UltraSite EDGE BTS with WCDMA functionality uses the same VXxx

transmission units for both GSM/EGDE and WCDMA transmission. However,the WCDMA transmission requires installing WCDMA transmission cables

between the IFU unit in the WCDMA part of the BTS and the VXxx unit in the

GSM/EDGE part of the BTS.

Also, a new WCDMA Upgrade Kit Transmission unit cover with different

mechanics is required to allow installing the WCDMA transmission cables.

Before routing and installing the WCDMA transmission cables, the existing

Transmission unit cover needs to be removed.

To remove the Transmission unit cover, proceed in the following working

order:

1. Remove the two screws from the Transmission unit box (see Figure 39).

2. Pull the bottom of the Transmission unit cover out from the Transmission

unit box while pulling down to disengage the tab and remove the cover.

To install the transmission cables and WCDMA Upgrade Kit Transmission

unit cover:

1. Depending on the desired WCDMA configuration and on the existing

GSM/EDGE configuration, install as many additional FXC transmission

units (VXxx) as required. Refer to Nokia UltraSite EDGE Base Station,

Unit Installation.

2. Check the VXxx unit cross-connections with Nokia BTS Manager to see

which VXxx unit RX and TX connectors are available for connection to

the IFU unit in the WCDMA section of the BTS.

3. Depending on the type of the IFU unit in the WCDMA configuration,

connect the transmission cables between the VXxx, the WCDMA Upgrade

Kit Transmission unit cover and the IFU unit as listed in Tables 2 and 3.

See also Figure 40).

(To ease connecting cables, hang the WCDMA Upgrade Kit Transmission

unit cover from its hook to the common rack.)

Note

The connections in Tables 2 and 3 are examples only and present the principle

how to connect the transmission cables to the TX and RX connectors. The VXxx

and IFUx connections may vary depending on the actual WCDMA BTS

configuration.

Note

Nokia recommends eight first connectors (TX1 and RX1 to TX4 and RX4) are

used in making transmission cable connections.
