Why lte

Why LTE

  • Enhanced network capacity

    • Architecture renewal with Full IP focus

    • Multiband scalable Radio Technology

  • Improvements on connection scalability

    • From Smartphone to the “network of the things”

    • Heterogeneous NW – from macro site to femto

  • Additional wireless resources

    • More Spectrum (multiband) more efficiently used…

    • Wide area pervasive coverage requires low bands (<1GHz)

Beyond lte never stop evolution

LTE-Advanced

Wider bandwidth for higher performance

Exploiting more sophisticated Radio Transmission schemes

Self-Organising network to efficiently handle heterogeneous network

Relay to boost pervasive coverage

Conclusion

Conclusion

  • Mobile Broadband demand will put under stress of the available capacity

    • Technology will be the enabler of Mobile Broadband but its success is rapidly exposing its limits

  • Long-term success is not based on any one innovation and it is not based on any one company

    • It is based on a harmonic growth of the entire data delivery chain

    • It is based on how the industry works together

      • Network operators

      • Equipment manufacturers

      • Device makers

      • Software providers

      • Regulators
