3.2 Terminology

3.2.1 The Mobile Telephone System

Figure 9 RBS 2000 in Ericsson’s GSM System

The BSS (Base Station System) contains two functional entities:

• The BSC (Base Station Controller) handles the radio-related

functions such as hand over, management of the radio network resources, and cell conﬁguration data. It also controls radio frequency power levels in base stations and mobile stations.

• The BTS (Base Transceiver Station) is the radio equipment needed

to serve one cell. It consists of the antenna system, the radio frequency power ampliﬁers and all the digital signal processing equipment. RBS 2000 contains equipment for 1 − 3 BTSs.

3.2.2 Antenna System

Is constituted by all RF transmission and reception antennas, directed to cover the same area or multicasting conﬁguration.

Antenna Reference Point (ARP)

Two ARP are deﬁned in this document; the RBS ARP and the AAU V

-ARP. The RBS ARP is the feeder connector on the RBS. The AAU V-ARP is the test connector after the network that connects

the outputs from different PAM:s. This network is used for test purposes only.

V=Virtual

3.2.3 Basic Conﬁguration

A maximum of two transceivers can be combined and connected to one antenna system.

The basic conﬁguration may be multiplied or used in combination with other basic conﬁgurations to build the needed site equipment.

3.2.4 Deﬁnition

The deﬁnition of the basic conﬁguration type thus refers to CDU_type. <Basic_Conﬁg>::=<X><F>d_<A>.<T>\<N>

3.4 General

RBS Conﬁgurations is the designated expression for the RF parts integrated in the BTS.

The functionality is:

• The output signal from one or more transmitters are combined

into the same antenna system, which can be utilized as a TX/RX antenna.

• The received signal from the receive antenna system, which can

be utilized as a TX/RX antenna, is distributed to receivers belonging to one RBS.

3.5 Conﬁgurations

3.5.1 TX Output Power

The value given for the RBS output power for the different conﬁgurations below is the minimum RBS output power when the transmitter is set for maximum nominal power (P0).

The RBS output power is measured at the TX reference point, and it is dependent on the TX combining and ﬁltering parts.

The tolerance for the RBS output power at the different settings is in compliance with /GSM:05.05:4.1.2/ for GSM 900 and GSM 1800, and / PCS:5.3.3/ for GSM 1900.

When two or more transmitters are combined to one antenna, the transmitters must be operated with a minimum of 400 kHz separation between the centre frequency of adjacent carriers. This limitation is not caused by the combiner but the RBS itself.

With TX diversity conﬁgured both transmitters use the same ARFCN. The maximum nominal power, P0, measured on the cabinet output RF

connector (which in this case corresponds to the TX Reference Point) is minimum +32 dBm. This output power level is valid for all frequency bands.

With TX diversity conﬁgured the output power is minimum +32 dBm at each ARP.

3.5.2 RX Description

The receiver system performance is dependent on the conﬁguration.

Actual sensitivity level

Is deﬁned in and complying with the level where RBS meets the reference sensitivity performance deﬁned in:

- /GSM:05.05:6.2 / for GSM 900 and GSM 1800

- /PCS:4/ and /PCS:5.1.1/ for GSM 1900.

Radio reception

The receiver sensitivity is reduced when a third order intermodulation product, generated by the radio transmitters in the RBS, is received at the same RCFN as the useful signal.

This occurs when the distance in frequency between two simultaneous transmitters is chosen in a way that a third order intermodulation product is generated at the same frequency as the operating frequency of one of the receivers in the RBS.

Note: In RBS 2301 the receiver sensitivity will be decreased by 1

dB when a third order transmitter intermodulation product coincides in frequency with an active frequency used by the receiver.

3.5.3 Isolation values

The isolation requirements between two antennas belonging to the same RBS is reduced and shall at least be:

- for GSM 900: 15 dB

- for DCS 1800 MHz and PCS 1900 MHz: 20 dB

- for Maxite, GSM 1800 and GSM 1900: 30 dB
