Key ConsiderationsIntended coverage areasCharacteristics of building walls/ceilingsNon-accessible areasEase of installation and maintenancePossibility of getting approval from building owner

BTS Location


Bts’s are located in several different locations inside the buildingBts/Antenna locations are picked according to specified service criteria to be met (coverage area and quality), affecting factors are:

size of areanumber of floorsnumber of passive unitslength and type of feeder runsattenuating materials, walls etc.

Possible bts locations are i.e. service rooms, in building warehouse rooms, service corridors, cleaning rooms, maintenance rooms, power distribution rooms, parking halls, etc. Before deciding on bts locations consider

is the bts in the most economical location ( power & distance to antennas, minimal amount of passive units etc.)is the feeder lines as short as possible (minimal amount of CW, feeder cost, attenuation)is the antenna in the most economical locations ( minimal amount of CW, passive units )where is the power source for the bts where and how is the AC power cables run to the bbuwhere and how is the TRS cable run to the TRS equipment (MW on the roof)can antennas be located more economically and still meet the requirements

ANTENNA CONFIGURATION CASES

Case 1


Antenna

Thick outer wall with high attenuation and thin inner wall with little attenuation e.g. basement carpark

Little leakage to outdoorLow interference from

outdoorLess antenna, higher output

powerEasy to plan for frequency

reuse between buildings

Case 2

Big glass windows with almost no attenuation to the surrounding e.g. open office environment

Lots of leakage to and from the surrounding

More antenna, lower output power

Distance to co-channel cell has to be large or shadowing building in between or use dedicated frequencies


Case 3

Lots of inner supporting walls causing attenuation e.g. hotel rooms

Need more antenna to keep leakage down while maintaining coverage


Antenna configuration for multi-storey building

O = Antenna

Antennas are recommended to be placed in a zigzag manner to get as even distribution of the signal strength as possible



Distributed Antenna SystemProblems – Recommendations - Result

DAS - Office Building


DAS - Office Building


Problem• Building is tall compared with the surrounding buildings• Frequencies are very tightly re-used in the area• High interference• Therefore required signal strength is -65 dBm

Recommendation• A distributed antenna system consisting of 11 antennas, 5 omni and

6 panel• Antenna EIRP = 6 dBm

Result• Full coverage. Evenly distributed signal strength and a low amount

of radiated power to the surroundings

DAS - Car Park


DAS - Car Park


Problem• Very low interference from outdoor• Therefore signal strength required is -90dBm

Recommendation

A distributed antenna system consisting of 7 omni antenna• Antenna EIRP = 8 dBm

Result• The antenna are distributed in such a way that the critical spots (lifts,

escalators, car ramps) have good coverage

DAS - Shopping Mall

Directional Antenna

0 25 50 75 100 m

Omni-directionalAntenna


DAS - Shopping Mall


Problem• There is a need both for better coverage and increased capacity in

the building

Recommendation• A distributed antenna system consisting of 4 antennas, 2 omni and 2

panel• Antenna EIRP = 10 dBm

Result• The antenna are distributed in such a way that all passages have

good coverage, and therefore quite a lot of traffic is caught. Signal is spread outside the mall, but mainly takes traffic from the nearby streets, which is good in this case.

• Metrosite GSM/EDGE max power consumption (DC) is 550W (worst case scenario)• Metrosite 50 max power consumption (DC) is 700W ( worst case scenario)

• BTS cabinets can be either pole mounted, wall mounted or laid on its back on a tray/shelf• Cabinets can be mounted vertically or horizontally (horizontally with 3 deg tilt)• Micro BBU can be pole mounted, wall mounted or floor mounted on a plinth

For Metrosite GSM/EDGE use one 16A breaker

For Metrosite 50 use 32A breaker (=using connecting bridge)

Additional capacity for GSM Metrosite

• Metrosite GSM/EDGE can be expanded to max 12trx’s, 3 cabinets under 1 BCF object

• Expansion is done with chaining bts’s through the VIFA interface units

• Chaining kits available in 1, 3 and 5m lengths• BTS 1 is the master bts, trx 1 of that bts is the

master trx• Lower “EXT” port in bts 1 VIFA card needs a

termination connector (comes with the kit)• TRS cards in slave 2 & 3 bts needs to be removed

and replaced with transmission shield units
