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

Dual TRX module (2HU)• 2 carrier unit• Either stand-alone or part of Sector

module

Main modules of Flexi EDGE BTS

HU = 44.4 mm

Slot for0-2 WBC’s

Slot forTRS interface


Main modules of Flexi EDGE BTSDualTRX needs to be paired either with DDU or RTC

System module

Dual duplexer module andWideband combiner submodule (optional, for all bands)

Dual TRX module

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

System extension module


Flexi EDGE - Cost Optimized Configuration (3+3+3)

TRX for extension

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


Flexi EDGE Upgrade Optimized Configuration 3+3+3

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

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.
