Nokia MetroSite Mast-Head Solution

Nokia MetroSite BTS in the

mast

- Capacity from 1 to 12 TRX with any configuration or cell number

- 1-3 MetroSite BTS, depending on capacity- Only one E1/T1 transmission link needed

- BBU can be installed at lower height

No shelters, no site support, no air conditioning needed

BTS connected with short jumper cable to antenna

- No feeder cable loss, less work, reduced investment- Only power cable to mast-head, distance not a limitation

Installation much easier than antenna- The plain chassis installed first (8 kg)

- Maximum 7 plug-in units per BTS

Why MetroSite Mast-Head Solution?

Extremely cost-efficient

Same coverage than typical macro BTS

5W/10W GMSK output power and feeder losses almost eliminated

High capacity: easy upgrade to 4+4+4

Easy to upgrade and maintain

Upgrades simply done with plug in units, no engineering competenceneeded in mast-head

High reliability ensure low OPEX and trouble-free operation

In case of any faults, just relevant plug-in units swapped, no need tochange the chassis, no engineering competence needed in mast-head

BBU installed at 5m height for easy maintenance, still vandal-proof

Wind load to mast same or less compared to macro BTS

No RF-cables up to mast, substantial reduction of wind load With one cross-polarised antenna per cell MetroSite footprint compared to

antenna footprint: MetroSite 1+1+1: 12%; MetroSite 2+2+2: 23%

Nokia MetroSite EDGE BTSRF Performance

This slideset gives RF performance values for GSM800, GSM900, GSM1800 and GSM1900

Nokia MetroSite EDGE BTS. These values can be used for customer tenders and as networkplanning values.

Given RF performance values only apply for EDGE capable TRXs:

The next pages describes how BTS output power and receiver sensitivity values are defined.

BTS Output Power:

Shown figures are nominal output power values, which are based on the average of productionmeasurements at TRX output connector

Output power values are with GMSK modulation. With 8-PSK modulation, values are 2 dB lessfor 800 and 1900, and 4 dB less for 900 and 1800 MHz.

Intelligent Downlink Diversity (IDD) doubles the received signal power at terminal and multiplediversity combining adds downlink gain by average of 2dB. Shown output power values areafter air combining without antenna gain.

BTS Receiver Sensitivity

Shown figures are nominal sensitivity values, which are based on the average of productionmeasurements at the BTS antenna connector - middle point of tolerance in TRX

BTS sensitivity values are given without any frequency hopping gain etc.

Receiving options:

2-way diversity = Rx signal is received with two antennas (one X-pol) and signals areconstructively combined using Interference Rejection Combining (IRC) method

Single branch = RX signal is received with one antenna

NOTE: In MetroSite, 2-way diversity is available when having two or more TRXs/sector, or byusing the optional TRX diversity module (available Q1/05 for 900 and 1800)

Usability of Metro site in BHARTI Project In Bharti project, the idea is to deploy Metrosites on tower top for the new town rollout.

However in a metro/ city scenario , metrosites can be deployed as coverage/capacity infillers and also asmicrocells

Metrosite Can only offer RX Diversity if it has minimum 2 TRXs in any sector. In the BHARTI project ,wherever Metrosite will be proposed for New Town or as Infiller , atleast 2/2/2 configuration will be deployed

This solution can be used upto 4/4/4 configuration with the 3 Metrosites chained together as describedbelow.

To increase the capacity expansion possibilities, Nokia MetroSite EDGE base stations can be chained asone BCF object to include up to 12 TRXs.Chaining is done by extending the BTS internal buses through theextension interface on the interface unit. Each BTS is connected to the next BTS in the chain with only onecable (up to five metres).Only one of the BTSs (the master BTS) incorporates a transmission unit (FXCtype).One BTS acts as the master BTS, in which the master TRX of the chain is located. However, eachBTS has a dedicated TRX to control the heating and cooling functions. The chained BTSs share the sameframe clock (FCLK) and frame number and the sector configuration is therefore not limited by the cabinetboundaries.

NOTE: The maximum distance between any 2 Metrosite Cabinets can only be 3 or 5m. For BHARTI casethe interconnecting cable being ordered is only 3m length.

Nokia Metrosite does not include a combiner in it. This implies that for any configuration above 2/2/2using Metrosite , there will be a need for additional antenna and antenna line.

Nokia Network planning currently is not recommending the use of any external combiners withMetrosite since these are 3rdparty products and their performance in terms of insertion loss etc isdoubtful.

Metrosite as a part of this solution should be placed as close as possible to the antenna. 3/8Jumper cable will be used to connect the Metro site to the antenna.

The Losses for 3/8 Jumper are: 13.9dB/100m for 900MHz & 20.5dB/100m for 1800MHz

Maximum Feeder + Connector loss that we are assuming for Metro sitesolution is 0.5dB. This implies that the maximum length of jumper that can beused is 1.5m.

Here are some more scenarios of Metrosite deployment :

2+2+2 Site on a Tower : Use 2 nos. Metrosite cabinets with 3 X-Polar antennas

Metrosite will be installed on a separate pole next to any one of the sectors. For connectingMetrosite to the sector which is next to it, use 1.5m 3/8 Jumper.

For connecting Metrosite to the other 2 sectors, use 1.5 m 3/8 Jumper if possible else use thecombination of 3/8 Jumper at BTS end + 7/8 SuperFlex cable .

Please note that even with the use of 7/8 SuperFlex cable , the maximum cable length canonly be 5m. This together with 1.5m of 3/8 Jumper will result in loss of 0.72dB for 1800MHz and 0.53dB for 900 MHz.

2+2+2 Site on a Rooftop : Use 2 nos. Metrosite cabinets with 3 X-Polar antennas in caseof a Delta or a tower on the rooftop.

Metrosite will be installed on a separate pole next to any one of the sectors. For connecting

Metrosite to the sector which is next to it, use 1.5m 3/8 Jumper.For connecting Metrosite to the other 2 sectors, use 1.5 m 3/8 Jumper if possible else use the

combination of 3/8 Jumper at BTS end + 7/8 SuperFlex cable .

Please note that even with the use of 7/8 SuperFlex cable , the maximum cable length can onlybe 5m. This together with 1.5m of 3/8 Jumper will result in loss of 0.72dB for 1800 MHz and0.53dB for 900 MHz.

2+2+2 Site on a Rooftop : Use 2 nos. Metrosite cabinets with 3 X-Polar antennas in caseof a poles on the rooftop and the distance between the poles is not more than 3m

One Metrosite cabinet will be installed on a separate or same pole next to any one of the sectors.For connecting Metrosite to the sector which is next to it, use 1.5m 3/8 Jumper.

The second Metrosite cabinet can be installed on the same/separate pole next to any of theremaining sectors. For connecting Metrosite to this sector, use 1.5m 3/8 Jumper.Howeverplease ensure that the distance between the 2 cabinets does not exceed 3m.

For connecting Metrosite to the third, use 1.5 m 3/8 Jumper if possible else use the combinationof 3/8 Jumper at BTS end + 7/8 SuperFlex cable .Please note that even with the use of 7/8SuperFlex cable , the maximum cable length can only be 5m. This together with 1.5m of 3/8Jumper will result in loss of 0.72dB for 1800 MHz and 0.53dB for 900 MHz.

Usability of Metro site in BHARTI ProjectTransmission with the Nokia MetroSite EDGE Base Station

FXC RRI transmission units are used with Nokia MetroHopper radios and/or NokiaFlexiHopper microwave radios. The FC E1/T1, FXC E1 and FXC E1/T1 transmission units are

used for wireline transmission.

Each Metrosite cabinet can house either one FXCRRI or FXC E1 card.

In case of chained Metrosites i.e. more than one cabinet connected together at one site, therewould still be one FXCRRI or FXCE1 card required and this will then act as the Master TRScard for the remaining cabinets also.

Metrosites can be used in Chain, Star or Loop topology.

One FXCRRI card can only provide 2 FB interfaces so incase a site with this solution becomesa convergence or nodal point from where more than 2 links are originating, appropriatesolution needs to be worked out considering FIUs.
