Flexi Multiradio BTS  NSN is the only vendor having track record of doing software radio upgrade: 3G upgrade to HSPA without HW changes

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

 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 rounds Around 500 000 LTE enabled Flexi BTS installed by now 4

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
