Introduction to Flexi EDGE BTS

On completion of this module the students will be able to:

Explain the need for a new platform Describe the concept of Flexi EDGE BTS

List the hardware differences between the current Nokia UltraSite BTS and the

new Nokia Flexi EDGE BTS


6/20



Why a new platform?

1. FIERCE PRICE COMPETITION, GROSS MARGINS UNDER HUGE

PRESSURE Produce a new platform having a clearly lower cost base

Substantial UltraSite cost reductions not easy nor cheap to achieve

2. MODERNISATION AND VENDOR EXITS OPEN UP POSSIBILITIES FOR

MARKET SHARE EXPANSION Increased market share with a new, differentiated offering

Instead of PIUs, design self-supporting (mechanically) compatible with Flexi WCDMA

Supports a wider range of site types with reduction of OPEX (when in stacks) and IMPEX

(enables new ways to build sites)

Despite being a modular BTS, it can also support traditional cabinet-based site designs


7/20



Revolutionary BTS with weather-proof modules

Installation in stacks, on walls, poles, in 19racks or cabinets

Same modules for indoors and outdoors, macro- and microcellular sites

Temperature range -33C +50 C (temporarily +55 C)

Site capacity with virtually no limits

1 to 24 TRX in 1-6* sectors under 1 BCF

Up to 216 TRX per site

24 TRX in the volume of a traditional BTS cabinet

Industry leading radio performance TRX output power 47 dBm, sensitivity115.5 dBm (with 2-way UL div)

Dual TRX module (DTRX) optimal for both capacity and coverage modes

In Capacity mode (CaM) both TRXs of DTRX are used for traffic

In Double Power TRX (DPTRX) mode the TRX output power is 49.5 dBm

In Coverage mode (CoM) 30-50% fewer sites by boosting both down- and uplinki.e., DPTRX+IDD+4-way diversity: 53 dBm (200W)

* Consideration in next SW revision to have 1-12 sectors

Nokia Flexi BTS platform:Novel approach for GSM/EDGE/WCDMA/HSPA/WiMAX BTS sites

BTS configurations are built with weather-resistantmodules

Capacity is expanded by

Adding modules

Software license keys

Same modules used for all site types

Indoor and outdoor Micro- and macrocellular

From 1 to 216 TRX configurations

Modules can be installed to walls, poles, stacks, 19racks,Nokia Flexi BTS cabinets or in swap-out situations

Common Nokia Flexi platform brings modularity to

GSM/EDGE and WCDMA/HSPA BTS sites Nokia is the first and only vendor to adopt the novel

modular approach


9/20



Nokia Flexi EDGE BTSA BTS built with modules

Cabinets are not needed with a module-based BTS Modules are weather protected by casings, covers

and connector boots and seals

Casings direct air-flow and allow removal of the

modules from the stack

Temperature range:

-33C +50C; temporarily +55 C

Modules can be installed in cabinets or 19 racks

Casings are not used in cabinet installations

Back and front covers are not used if cabinets have

a door

Modules are small and light-weight

One person can transport and install BTS withoutusing lifting equipment

Stack installation of Nokia Flexi BTS

BTS modules are placed in a stacked (e.g. floor or

shelves)

Outdoor & indoor installations

Modules in casings with back and front covers

Plinth needed (same plinth for all cabinetless

installations)

Max 9 modules per plinth for zone 2 earthquakezones, max 5 modules for zone 4 earthquake

zones

Standard Nokia Flexi BTS clearances apply

Wall installation of Nokia Flexi BTS

BTS modules installed on a wall

Outdoor & indoor installations Modules in casings with back and front covers

Plinth needed

Up to 2 modules per plinth

Modules installed covers sideways

150 mm space recommended between plinths

to enable cabling (see picture)

Nokia Flexi Cabinet installation of Nokia Flexi EDGE

BTS Up to 24 TRX configurations per Nokia Flexi BTS cabinet

Cabinet can simultaneously house GSM/EDGE, WCDMA/HSPA and BBUmodules

There are no limitations on how to mix GSM and WCDMA in the cabinet

Optional Nokia Flexi Cabinets for indoor and outdoor installations

Open 19 mechanics with 1 HU fixing steps for flexible module installations

No motherboards or electronics (fans etc)

Not part of EMC shielding Only front cabling

Module casings and covers are not used

Cooling fans remain in modules

Modules are grounded via rack

Same footprint and cabinet fixing points as with

Nokia UltraSite and Talk Family

Outdoor: 1450 x 770 x 770 (H x W x D), space for 38HU

Indoor: 1800 x 600 x 600 (H x W x D), space for 36HUNokia Flexi BTSOutdoor Cabinet

19 Rack Installation of Nokia Flexi EDGE BTS

Where space and thermal conditions allow modules can be installedin a standard 19 rack, or existing cabinets

BBU, site support, legacy BTS

Racks used as mechanical housings

Racks give protection for extreme conditions

Max configuration depends on rack height andmechanical performance

Casings are not used

Front and rear covers not used if there is a door and back wall are required for safety reasons if there is no door or back wall

Only front cabling, no back access required

Every module is fixed separately to the rack

Rack provides 19 fixing points

Modules are grounded via rack

Sufficient air flow through rack must be guaranteed

Min 100 mm front clearance for connectors andcables is needed if there is door
