Flexi Multiradio 3-Sector RF Module

Flexi Three Sector RF Module with 3 x 70 W power amplifiers is 3 x 60 W at the antenna connector • Improved OPEX, electricity consumption is 25% lower than previous generation RF • 1+1+1 LTE with one RF Module • Up to 4+4+4 WCDMA with only one RF Module • WCDMA Dualband, e.g. 2+2+2 (band1) and 2+2+2 (band2) with only two RF Modules • Outdoor IP65 , -35 … +55 °C • Support for Distributed site up to 20 km from System Module

Ant6 Ant5 Ant4 Ant3 Ant2 Ant1

The most cost and size optimized 3-sector configuration


System Module

• Easier Installation • Less wind load and weight • One optical and DC cable to tower Standard Flexi RF Module can be installed close to antenna for maximal performance

⇒ No need for MHAs ⇒ no feeders ⇒ easy dual band

3-sector 3 x 60 W

RF Module IP65

with DC max 200 meters

Flexi Multiradio BTS Feederless


• one RF Module per sector • Max 60 + 60 W per cell with 2TX MIMO • 60 W per 2 carriers (WCDMA)

• Optional 4 way UL diversity (SW according to RA roadmaps)

Most powerfull solution on sites where one RF unit per sector required

Co-siting Scenario – Stacked Installation

• Flexi Multiradio BTS requires smallest footprint to deliver highest capacity

• BTS modules can be either – Stacked on floor next to

existing legacy BTS – Stacked on top of existing

• Flexi Multiradio BTS compactness allows for installation in standard 19” rack

• BTS modules can be placed inside a legacy 19” cabinet if space is available – No additional footprint

required to deliver LTE


Co-siting Scenario – Rooftop/Antenna Installations • Flexi Multiradio BTS modularity

makes it the best fit for tower top applications

• Provides for industry leading efficiencies – 3-sector configuration in one

module – Low wind loading and weight

• With separate legacy and LTE antenna elements the need for combining is eliminated
