Nokia Flexi EDGE BTS: from small to large configurations
Flexible capacity increase from small to very large configurations
• 1 to 24 TRX in 1-6 sectors under 1 BCF
• up to 216 TRX per site
High site capacities possible even without a cabinet
All dual band configurations supported
• ANSI and ETSI frequencies
• GSM 800/1800, GSM 800/1900, GSM 900/1800
Min configuration 1-2 TRX , 2 modules
Max configuration / BCF 8+8+8 TRX, 14 modules

IDD and 2-way RX diversity (with MHA) Example: 1 TRX/cell
• Intelligent Downlink Diversity (IDD) is an effective way of boosting the downlink: it is based on space and time diversity and signal tuning
• IDD gives on average 5 dBm gain in downlink path

Nokia Flexi EDGE BTS output power
BTS nominal output power values are measured at the Dual Duplexer module’s antenna connector (same as TOC figures of traditional cabinets)
Output power values are defined with GMSK modulation. With 8-PSK modulation, values are 2 dB smaller.
Intelligent Downlink Diversity (IDD) doubles (~3 dB) the received signal power at the handset and multiple diversity gains add downlink by average of 1-2 dB, giving average 4.5 dB gain in total. Shown output power values are after air-combining without antenna gain.
Combining options: • Combiner by-pass = No combining – 1 TRX to one antenna
• WBC 2:1 = One stage Wide Band Combining – 1...2 TRXs to one antenna
• WBC 4:1 = Two stage Wide Band Combining – 1...4 TRXs to one antenna
• RTC 6:1 = Remote Tune Combining (cavity combining) – 1...6 TRXs to one antenna
Output power values for RTC are given with 6 TRX and minimum channel spacing. With less TRXs and extended channel spacing, output power is up to 0.5 dB higher.

TRX Capacity Licence control in BSC
BSC checks that the licence is valid and that operator cannot have more Flexi EDGE TRXs in use than the licence allows.
Operator can also check the amount of Flexi EDGE TRXs that are in use.
The current capacity level usage is requested with service fmn_capacity_usage_inquiry_as from BSC software that has registered itself as capacity manager (PUBDAT).

Feederless Concept Masthead Solution
• One EOCA pair is needed per 3 DTRXs. In 3 sector system each EOCA pair supports 2+2+2 configuration.
• Maximum of 4+4+4 is supported in masthead configuration.
• Each 2+2+2 requires own DC Feed and Optical Fiber. This replaces six antenna feeders of 3-sector diversity configuration.
• Benefit in 4+4+4 configuration is smaller due to no new antenna feeders are required in feeder case and 2nd pair of DC and optical interfaces are needed in feederless case.
• 2+2+2 4-way diversity case saves 12 antenna feeders with two sets of DC and optical interfaces.

Feederless Concept Rooftop Solution
• Rooftop installation is mainly assumed to be 3-sector configuration.
• One corner is assumed to have one sector as local sector with System Module (and extension system module if over 6 DTRXs in system).
• Other corners are as remote sectors so overall two EOCA pairs are required for upto 6+6+6 configuration.
• Single Optical Cable and DC feed is needed per each remote corner upto 6+6+6+ configuration.
• Upto 8+8+8 configuration is supported with two EOCA pairs per remote sector.

Unit Construction Interfaces
• EOCA contains: – Three BUS interfaces (one from back as pre-installed longer cable interface)
– Three 48V DC Output/Sense interfaces (one from back as pigtail interface)
– 48V DC input interface
– Optical Fiber Interface
– OVP Plug-In Module interface
• BUS interfaces are connected to ESMA or ESEA at local end and to DTRXs at remote end.
• 48V output/sense interfaces are connected to DTRXs at remote end. At local end they can be connected to ESMA if sensing is used. 48V control can be handled purely as commands over Ethernet and likely sensing will not be supported eventually to reduce amount of cables needed in the setup.
• Optical interface is connected between EOCA of local sector and EOCA of remote sector.
• DC inputs are connected to 48V source at local end. Remote can get its 48V from local end or locally from the 48V source at remote end.
