Taking the next steps

∙ Cellular band fragmentation continues

∙ SAW less transmitter solutions are already here

∙ The next step is reducing or even removing SAW filters in receivers

Illustration: 40nm SAW-less prototype transceiver for 0.4-6GHz proposed by Dr. Jan Craninckx at IMEC (ESSCIRC Tutorial on Cognitive and Software defined radio)

∙ 65% of all allocations are 10MHz or less

∙ Very few 20MHz allocations

∙ No 20MHz LTE FDD allocations in the US

∙ Many operators struggle to deploy true 100Mbps services

∙ Carrier aggregation, meaning multiple parallel carriers, is the solution

Conclusions

Innovation race in telecommunications continue

New design methodology and soft, scalable architectures for radio modems

Flexible, scalable solutions with wide range of bands support offers economy of scale for OEM and Carriers

Few end product reasons to stay with 2G or 3G

ST-Ericsson demonstrates all of this in its roadmap
