Flexi Multiradio BTS

Exactly same Hardware means: Flexi LTE System Module volume deliveries have

been in progress already over one year Component, production, field hardening,.. All

taken place in volume already now with HSPA SW

NSN 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 technology developed by Texas Instruments together with NSN

1.5 Years advance on technology availability

No delays / field retrofits due to new ASIC roundsAround 500 000 LTE enabled Flexi BTS installed by now

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 ‘industry default’ ~40 W


• A new level of BTS energy efficiency was set with Flexi WCDMA BTS

• 3-sector Flexi Multiradio BTS in typical WCDMA operation will now consume only 430 W
