4 Configurations for MetroSite EDGE BTS

4.1 Overview of configurations for MetroSite EDGEBTS

One Nokia MetroSite EDGE BTS incorporates up to four transceiver units andthus provides sufficient capacity to handle a large amount of telecommunicationtraffic. Nokia MetroSite EDGE BTS can be sectored very flexibly. Everytransceiver unit has its own antenna connector. Every transceiver unit alsoincorporates a duplex filter, and one antenna therefore handles both transmittingand receiving. Any cell can incorporate up to four transceiver units and, on theother hand, every transceiver unit can form a sector of its own within a cell. Asector consists of one broadcast control channel (BCCH) transceiver unit and,often, one-to-three traffic channel (TCH) transceiver units. The maximumnumber of transceiver units in one sector is four.

At the BSC, one of the slave transceiver units is by default defined as the BCCHtransceiver unit. The BCCH transceiver unit is the most likely transceiver unit toneed replacement and a slave transceiver unit can be replaced withoutinterrupting the BTS operation. If desired, the BCCH can be forced on the mastertransceiver unit by using the preferred BCCH feature at the BSC.

By using the different sectoring possibilities provided by Nokia MetroSite EDGEBTS and by directing the antennas, different types of coverage areas can becreated. The actual shape of the coverage areas varies depending on theenvironment.

The dual-band feature enables the operator to configure any sector to operateeither on a 900 or 1800 MHz frequency, thus increasing the capacity of thenetwork. CXM3.3 (or later) software (for 850 and 1900 MHz frequencey bands)or CXM3.3-1 (or later) software (for 900 and 1800 MHz frequency bands) mustbe available at the BSC.

850/1800 MHz and 900/1900 MHz dual-band frequencies are also possible.



Configurations for MetroSite EDGE BTS

Note

The term “cell” is used in the network management system (NMS) context,referring to the coverage area of transceivers from the same base station.

Transceiver units from different sectors can be connected to one antenna. Thefollowing examples assume that the MetroSite antenna is used. The diversityapplications may differ from the examples presented here, if different antennatypes are used.

. Example configuration: one-sector, single-band configuration

. Example configuration: four-sector, dual-band configuration

. Example configuration: one-sector, dual-band configuration

. Example configuration: Intelligent Coverage Enhancement (ICE)

4.2 Example configuration: one-sector, single-bandconfiguration

The following figure presents a single-band (GSM/EDGE 900) BTS that has fourtransceiver units in one sector. The antennas are directed to the same direction.The resulting coverage area comprises four transceiver units.

In order to employ diversity, it is most feasible to connect the transceiver unitsthat share the diversity to different antennas.



Figure 2. Four transceiver units in one-sector, single-band configuration

Another way to build overlapping GSM/EDGE 900 and GSM/EDGE 1800 cellsis to direct single-band GSM/EDGE 900 and GSM/EDGE 1800 antennas towardsthe same direction.

The BTS can be used to build fill-in coverage in areas that are difficult to reachwith conventional base stations. In these cases, it is recommended that high-gainantennas are used.

Antennas directed to form one coverage areaincluding 4 GSM/EDGE 900 TRXs.

4.3 Example configuration: four-sector, dual-bandconfiguration

With dual-band antennas, such as the MetroSite antenna, overlapping GSM/EDGE 900 and GSM/EDGE 1800 coverage areas can be created by connectingtransceiver units from a GSM/EDGE 900 sector and transceiver units from aGSM/EDGE 1800 sector to one antenna.

The following figure shows schematically the coverage areas created with a BTSthat has four sectors (two GSM/EDGE 900 sectors and two GSM/EDGE 1800sectors) in a (1+1)/(1+1) configuration. One GSM/EDGE 900 and one GSM/EDGE 1800 sector are connected to each antenna. The antennas are directed todifferent directions.



Figure 3. (1+1)/(1+1) dual-band configuration

4.4 Example configuration: one-sector, dual-bandconfiguration

The 2+2 dual-band configuration can be used to build one directional dual-bandcoverage area. This configuration has one GSM/EDGE 900 sector that includestwo transceiver units, and one GSM/EDGE 1800 sector also including twotransceiver units. One transceiver unit from the GSM/EDGE 900 sector and onetransceiver unit from the GSM/EDGE 1800 sector are connected to one antenna.

4.6 Transmission connections

This section describes the transmission topologies that can be built by using thetransmission unit capacity of Nokia MetroSite EDGE BTS. The transmissionnode that expands the transmission capacity is typically the Nokia MetroHubTransmission Node. For more information on the larger configurations, refer toNokia MetroHub Transmission Node documentation.

The transmission unit takes care of the transmission between Nokia MetroSiteEDGE BTS and the BSC through the Abis interface. The transmission media canbe either radio link (RRI), optical fibre (STM-1), or wireline (E1/T1).

FXC RRI transmission units are used with Nokia MetroHopper radios and/orNokia FlexiHopper microwave radios. The FC E1/T1, FXC E1 and FXC E1/T1transmission units are used for wireline transmission. The FC STM-1 unit is usedfor transmission via optical fibre.

Note

When EDGE transmission is being used, the FC E1/T1 transmission unit is notrecommended because of the high-data transfer rates that are possible withEDGE.

The FXC RRI, FXC E1, FXC E1/T1, and FC STM-1 transmission units have across-connect capability. The bidirectional connection between two interfaceports (B2 cross-connection) can be made with 2M, nx64k, 64k, 32k, 16k, and 8kgranularities. Granularity refers to the number of bits connected into a specificdirection in the cross-connection. In addition, the FC STM-1 offers cross-connectcapability at the VC-12 layer.

In addition to digital speech data, the FC STM-1 transmission unit can alsotransfer operating and maintenance information to other equipment in thenetwork. The FC STM-1 unit provides the following main features:

. Two STM-1 L-1.1 long-haul optical interfaces

. Automatic laser shutdown (ALS)

. Both SDH STM-1 TM and STM-1 ADM (in chaining configuration) nodetypes

. Fully non-blocking cross-connections on TU-12 level between both STM-1 aggregate interfaces and the add/drop traffic



. SDH S12 SNC/I+ (Inherently monitored subnetwork connectionprotection), that is, protection on the VC-12 level

. Up to 4 x TU-12 (2M) drop capacity from SDH

. Grooming via PDH cross-connections for the add/drop traffic with thefollowing granularity: 8k, 16k, 32k, 64k, Nx64k

. Interface statistics collection in compliance with ITU-T G.826

. Easy management of settings and transmission configuration (locally andremotely) with the Nokia Q1 management protocol; management is carriedout with a Nokia NetAct compatible node manager

. Remote and local software download

FC E1/T1 transmission units are used in the termination points of thetransmission chain.

Depending on the type of transmission unit, it is possible to use the followingnetwork topologies:

. Chain connection (see A and B in Examples of transmission connectionsfigure)

. Star connection (see C and D in Examples of transmission connectionsfigure. With the radio transmission alternative, the centre point of the star isalways a transmission node.)

. Loop connection (see E and F in Examples of transmission connectionsfigure)

Nokia MetroSite EDGE BTS supports 16 Kbit/s, 32 Kbit/s and 64 Kbit/s AbisTRX signalling. The O&M signalling speed alternatives are 16 Kbit/s, 32 Kbit/sand 64 Kbit/s. To optimise the use of transmission capacity, combined O&M andTRX signalling is also supported at all these speeds.

Locally, the transmission configuration is managed with the Nokia BTS Manager.Information on how to create different transmission configurations can be foundin the BTS Manager’s on-line Help.

Note

Since EDGE can carry higher data rates than GSM, the specification of thetransmission unit and its configuration should be of suitably high capacity whenusing GSM/EDGE TRXs.

General guidelines

Warning

Do not disconnect the antenna when the BTS is transmitting!

Warning

This equipment generates electromagnetic radiation which can exceed safetylevels when a person is working in very close proximity to the antennas.Calculate and observe the minimum safety distance precautions whenworking in close proximity to antennas operating at full power!




Warning

Electromagnetic radiation can leak from loose or improperly connectedantenna connectors. Personnel must ensure that antenna connectors areproperly connected when carrying out procedures such as installation andcommissioning and must not touch unshielded connectors when RF power ison.

Warning

Do not install the BTS or its antennas in areas where there is a potential riskfor interference with inadequately shielded medical equipment, such as lifesupporting devices, hearing aids or other electrically or magneticallysensitive devices!

Warning

When installing the BTS or its antennas, the emission of other antennasnearby must be known beforehand so that ambient emissions can bemanaged properly.

Formula for minimum safety distances

Figure 7. Formula for calculating minimum safety distances

The equation refers to the following factors:

rmin =N10 P4 S

(G-L)

10

DN02152589

out



. G is the antenna gain (in dB) compared to isotropically radiating antenna

. P is the power delivered to the antenna (W)

. L is the total loss (in dB) between the transmitter and the antenna input

. N is the number of transmitters combined to the antenna

. S is the maximum allowed power density in air (W/m2).

Formula for maximum power density

Table 4. Calculating maximum power density, in preparation for a safetydistance calculation

Environment Formula / Description

Controlled Environments* The minimum distances are calculated using thereference levels for maximum power density pre-sented in the CENELEC test standard EN50360:2001, as follows:

For the frequency range 400 to 2000 MHz, S = f/40 W/m2 (where S is the maximum power densityand f is the frequency in MHz) averaged over any6 minute time interval.

For example, Smax for 5W at 900 MHz is 22.5 W/m2.

These reference levels are in agreement withother guidelines (such as IEEE/ANSI, IRPA,NCRP, FCC).




Table 4. Calculating maximum power density, in preparation for a safetydistance calculation (cont.)

Environment Formula / Description

Uncontrolled Environments* The minimum distances are calculated using thereference levels for maximum power density pre-sented in the CENELEC test standard EN50360:2001, as follows:

For the frequency range 400 to 2000 MHz, S = f/200 W/m2 (where S is the maximum powerdensity and f is the frequency in MHz) averagedover any 6 minute time interval.

For example, Smax for 5W at 900 MHz is 4.5 W/m2.

These reference levels are in agreement withother guidelines (such as IEEE/ANSI, IRPA,NCRP, FCC).

* Controlled environments refer to locations where there is exposure to personsaware of the potential exposure. Uncontrolled environments refer to locationswhere there is exposure to persons not aware of the potential exposure and whohave no control over it.

5.8 Grounding (earthing) requirements

To protect the BTS from damaging over voltages through antenna equipment,communication cables, or power supply lines, grounding cabling must be plannedand installed before installation of the base station. To avoid interference, it isrecommended that large grounding systems be designed case-specifically.

An electrical plug with a ground connection is not sufficient for the BTS.Grounding must have a fixed, non-removable connection.

Note

Regulations issued by local authorities must be followed when planning thegrounding of a BTS site!

Note

A grounding cable can be ordered from Nokia.

In general, grounding is planned according to the following requirements:




. The grounding cable is connected to the grounding points inside the BTScabinet.

All Nokia MetroSite EDGE Base Stations are equipped with twogrounding point alternatives: a cable clamp location and a pair ofgrounding studs. Selection is made in accordance with local regulations.

. The minimum cross-section of the grounding cable's copper (Cu)conductor is 16 mm2 (5 AWG) in outdoor installations. In indoorinstallations, the minimum cross-section of the copper conductor is 2.5mm2 (12 AWG).

. The maximum cross-section of the grounding cable's copper conductor is35 mm2 (2 AWG).

. The maximum value for ground resistance is 10 mΩ.

. The grounding cable must be connected to a main grounding bus bar.

. The routing of the grounding cable must be as direct as possible.Unnecessary loops should be avoided.

. The external antenna feeders must also be grounded if the antennas areexposed to the risk of lightning.

5.9 Current limiting protection requirement

Caution

For 850 MHz and 1900 MHz frequency units to meet the requirements of GR-1089-CORE an approved external current limiting protector (such as heat coils)must be fitted to the FXC E1/T1 ports to protect them from over-current faultconditions!

5.10 Wall requirements

The installation must be inspected by qualified personnel before mounting theBTS. This is to ensure that the mounting is strong enough to bear the weight ofthe BTS (maximum 40 kg / 88.2 lb) in its operating environment.

Anchor screws are used for attaching the Nokia MetroSite EDGE Base Station tothe wall. These screws are not included in the delivery.



The anchor screws must be M6 size, stainless steel, and with the minimumbreaking strength (Rm) of 800 N/mm2. An appropriate mounting counterpart forthe anchor screw (such as an anchor plug) must be selected according to thescrew and the mounting base material. If the anchor screws are of a type otherthan metric, they must be selected to meet the strength requirements mentionedabove.

5.11 Pole requirements for pole installation

The installation wall or pole must be inspected by qualified personnel beforemounting the BTS. This is to ensure that the mounting is strong enough to bearthe weight of the BTS (maximum 40 kg / 88.2 lb) in its operating environment.
