(32 pt makes 2 rows









Coverage expansion of mobile broadband into areas with fewer potential subscribers presents a challenging business case.

Nevertheless, Coverage is King, and a key differentiator between operators.

-Coverage solution provides accelerated deployment of 3G coverage enabling more sites within a fixed budget, with large OPEX savings.

-coverage - whylike-for-like coverage less capex and opex

1 standard R/RUS

1 standard DUW

Add 2 R/RUS

New HW enabling one radio to provide the uplink coverage of

three radios

New -Coverage SW enabling uplink capacity of a 3x1


(32 pt makes 2 rows









new HW tmf

1 standard R/RUS

1 standard DUW

TMF size (2100MHz B1) 18x26x6,7cm (3,1 litres)*

TMF supports Remote Electrical Tilt of the antennas (AISGv2.0)

*RRUS-01 23 litres

For one radio to provide the coverage of three radios, one receiver must act as three receivers

TMF = Frequency Shifting TMA

20 MHz receiver

5 MHz Antenna 1

5 MHz Antenna 2

5 MHz Antenna 3

The TMF shifts the frequencies so the multi-carrier receiver can act as three single-carrier receivers.

The RX sensitivity of each receiver is maintained.

In WCDMA, the same frequency is used in the air on all antennas.

New hw-combiner

1 standard RRUS

1 standard DUW

The robust -Combiner connects three antennas & TMFs to one radio.

It allows flexible antenna placement in the same way as a 3-sector site, maintaining

optimum radio performance when using

TMF

-Combiner (3 antennas) size 13x20x10 cm (2,6 litres)

Y-Combiner (2 antennas) size 12x18x9 cm (2 litres)

The combiners support Remote Electrical Tilt of the antennas (AISG v2.0)

Pre-installation activities

› RNC19 upgraded to W11B– Minimum RNC SW to work with W12B -Coverage Node-B

› OSS-RC upgraded to O12.2– New pm counters for uplink cell portions– O11.3 minimum needed for remote SW upgrade

› Site selection current 3x1 sites– Input < 10 GByte/day data– Input < 30 Erlangs speech busy hour

› Sites 1556 and 1572 upgraded – From 3418 to 6601 + DUW

› SW licence -Coverage optional feature› HW activation codes (up to 80W)› HW purchased

– One RRUS-01, RF jumper cables, RET cables– 3 TMFs, -Combiner and Address Adaptor Kit


(32 pt makes 2 rows









Key parameter settings (MOshell)

› Activate -Coverage license› One cell instead of three cells

– Configure Node-B (Element manager Export/Delete or moshell script)

– Output power increased to 80W– HSDPA users 16 or 32– EUL users 16 (or 12)– Codes 15, dynamic code allocation– Change neighbor cell relations

› Delete 2 cells, and relations involving these cells› Add relations from deleted cells to remaining cell› WCDMA-WCDMA, WCDMA-GSM, (no GSM-WCDMA)

› RBS 6000 node (for 3000 modernization)

Output power

› Several parameters to be set in RBS and RNC– Licence HWAC,

› licenseStateNum40WPowerAmplifiers 1 (ENABLED)› licenseStateNum60WPowerAmplifiers 1 (ENABLED)

› licenseStateNum80WPowerAmplifiers 1 (ENABLED) – Radio output power maximum

› moshell> set TpaDevice=1 maxTotalOutputPower 80

– RNC utrancell- maximumTransmissionPower 490

› CPICH unchanged– Potentially lower if max power is lower?

› Feeder attenuation keeps CPICH level into antenna– maxDLpowercapability 434 with 5,5dB attenuation – 490 -55 -1 (TMF) = 434


(32 pt makes 2 rows









Key parameter settings (MOshell)

› Different antenna system– antennafeedercable attenuation increased– 4,8+0,1 = 4,9dB for splitter/combiner (-Combiner)– Add jumpers between RRUS-01 and -Combiner– Add jumpers between -Combiner and TMF– 1/2inch jumpers ~0,2dB for 1,8m, ~0,3dB for 3m, ~0,6dB for 6m– Feeders 1dB per 16m for 7/8inch feeder– TMF included automatically in system

› TMFs configured using configuration tool– ARFCN number needed

› RETs configured – 1 AISGv2 RET per TMF

-coverage - where

Use cases:

1- Planned new rollout sites– Satisfying coverage and capacity at lower CAPEX & OPEX

– Go for low capacity new 3x1 sites, expand later 2 Radios when capacity grows

2- New coverage sites, that were not yet worth investment with 3 Radios

3- Modernize RBS3000 sites with low capacity, with efficient CAPEX & OPEX

4- Apply the feature on existing RBS6000 3x1 sites with low capacity, save power consumption and re-use Radios to expand other high capacity sites


(32 pt makes 2 rows









-Coverage traffic capability

- Target:

- Good KPIs and end user experience

- Good coverage

- Support traffic growth

- Recommendation:

- < 10 GByte/day (total data traffic) , < 8 GByte/day HSDPA data

- < 25 Erlangs busy hour speech, < 12 Erlangs daily average

- Applies for CPICH for < 12%

- For CPICH 12-16% reduce traffic by 20%

- For CPICH 17-20% reduced traffic by 40%
