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

rounds

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
