Flexi Multiradio BTS

Exactly same Hardware means:

Flexi LTE System Module volume deliveries have beenin progress already over one year

Component, production, field hardening,.. All taken

place in volume already now with HSPA SWNSN LTE BTS will not start from serial number #1

NSN is the only vendor having track record of doing software radio upgrade:

3G upgrade to HSPA without HW changes

Enabled by the most powerful BTS DSP technologydeveloped by Texas Instruments together with NSN

1.5 Years advance on technology availability No delays / field retrofits due to new ASIC

rounds

Around 500 000 LTE enabled Flexi BTS installed by now

• RF Modules support LTE and GSM in concurrent mode operation

• Common Multi Carrier Power Amplifier (MCPA) is used to transmit GSM andLTE

- RF output power is flexibly shared between GSM and LTE

- No external combining needed, reduced complexity for the antenna system

Flexi RF Module gives RF power for future

Downlink power is always limited …and future will require even more

Multiradio GSM + HSPA or LTE – GSM DL power i.e. coverage can not be reduced!

• HSPA Dual Carrier (10 MHz) and 2 x DC ( 20 MHz)

• HSPA Dual Carrier with 2TX MIMO• LTE 15 or 20 MHz bandwidth

• At many legacy sites not possible to install RF close to antennas

RF power reserve needed

=> Flexi 60 / 80 W is superior future proof solution compared to ‘industrydefault’ ~40 W




• A new level of BTS energy efficiency was setwith Flexi WCDMA BTS

• 3-sector Flexi Multiradio BTS in typicalWCDMA operation will now consume only430 W
