  1. Flexi EDGE BTS

  2. GSM System Architecture Our focus (BSS system)

  3. Urban feederless site application Up to 150 meters* Flexi BTS installation options Nokia, 3rd party BTS cabinet or SSS installation Stacked installation Wall installation Pole installation unique BTS *BB hopping reducing costs multiradio

  4. Main modules of Flexi EDGE BTS • Sector module (3HU) • Logical module comprising Dual TRX and Dual duplexer modules • System Module (3 HU) • O&M, power distribution, system bus • Dual duplexer module (optional) (1HU) • Duplexing & multicoupling, VSWR, Bias-T • Min 1/ sector; paired with Dual TRX module Slot forTRS interface • Dual TRX module (2HU) • 2 carrier unit • Either stand-alone or part of Sector module Slot for0-2 WBC’s HU = 44.4 mm

  5. Main modules of Flexi EDGE BTSDualTRX needs to be paired either with DDU or RTC Dual duplexer module andWideband combiner submodule (optional, for all bands) Remote Tunable Combiner (optional, only for 900/1800) RTC is low-loss, high capacity filter combiner supporting only baseband hopping DDU/WBC is a flexible high capacity combining method supporting both wideband and baseband hopping choose antenna combining option Dual TRX module System extension module + System module

  6. Flexi EDGE - Cost Optimized Configuration (3+3+3) • With Cost Optimized Configuration the amount of Dual TRX HW is optimized for cost • 3+3+3 -> 4+4+4 upgrade requires new DTRX and a site visit TRX for extension

  7. Flexi EDGE Upgrade Optimized Configuration 3+3+3 This TRX remotely activated for 4+4+4 • With Upgrade Optimized Configuration the Dual TRXs are not split between sectors. • 3+3+3 -> 4+4+4 upgrade can be done remotely by SW This TRX remotely activated for 4+4+4 This TRX remotely activated for 4+4+4

  8. Base station sites are the main energy consumers in a mobile network Other (controllers, core, OSS, etc.) 10% Site energy consumption (heating/cooling, etc.) 30% 90% BTS sites 70% BTS energy consumption

  9. Flexi EDGE Power Consumption Innovations • Disabling the PA bias when traffic goes down • Always enabled, on per timeslot basis • Decision to switch the bias on/off made dynamically by the BTS during start of each timeslot. BTS traffic load TS7 TS5 TS0 TS1 TS6 TS0 TS1 TS4 TS2 TS3 on on off on on off off off on on Copied to UltraSite TRXs manufactured Year 2007 onwards BTS power consumption Traditional BTS competitor efficiency low efficiency high BTS+ Flexi bias on bias off

  10. NSN Smart Site SolutionExample

  11. Flexi WCDMA – Feeder less Solution Flexi WCDMA and Flexi EDGE Flexi WCDMA – System module mounted on tower leg Flexi WCDMA – RF module mounted on antenna pole Flexi WCDMA - Feeder less Solution.

  12. Flexi EDGE – Aluminum Feeder Flexi EDGE – System and RF Module mounted on tower leg Aluminum Feeder – from the RF module to antenna system

  13. Tubular Tower with Platform Platform system for the equipments above the ground Platform system for the equipments and antenna system

  14. Solar System BTS traffic load TS7 TS5 TS0 TS1 TS6 TS0 TS1 TS4 TS2 TS3 on on off on on off off off on on BTS power consumption Traditional BTS competitor efficiency low efficiency high BTS+ Flexi bias on bias off Solar Panels Battery House

  15. Flexi offers a wide variety of benefits over traditional BTS designs: Flexi EDGE BTS vs. Traditional BTS Designs FLEXIBILITY IN SITE SELECTION Installation in wall, pole, Flexi cabinets,19” racks, Talk OD POWER CONSUMPTION -30% vs. UltraSite 2006 -15% vs. UltraSite 2007 -Real time PA shot down -DTRX complete shut down EASY INSTALLATION Cabinet not mandatory, no cranes Modules carried by one man MULTIRADIO SITES Complements Flexi story Flexibility for multiradio installations DIMENSIONS 24TRX in UltraSite 12TRX volume 4+4+4 in height of 86cm and 150kg PRODUCTIZATION More value in sw, lisencing for: MHA support, TRX capacity, DPTRX, TRS i/f & funct. TRANSMISSION ENHANCEMENTS Flexi optimized for tail and chain sites FlexiHub adds capacity and new interfaces Performance -Matching UltraSite RF -Feederless Site for cost effective coverage
