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 for TRS interface
Dual TRX module (2HU)
2 carrier unit
Either stand-alone or part of Sector module
Slot for 0-2 WBC’s
HU = 44.4 mm

5. choose antenna combining option
Main modules of Flexi EDGE BTS DualTRX needs to be paired either with DDU or RTC
Dual duplexer module and Wideband 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

6. Flexi EDGE - Cost Optimized Configuration (3+3+3)
With Cost Optimized Configuration the amount of Dual TRX HW is optimized for cost
> 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.
> upgrade can be done remotely by SW

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.
