La 5G, 15' pour (presque) tout comprendre

La 5G arrive à grands pas et de nombreux médias et industriels commencent à en parler. Ce fut notamment le cas lors duMobile World Congress (MWC) qui s'est tenu à Barcelone en mars dernier.

Alors que le processus de standardisation n'est pas encore tout à fait finalisé, certains d'entre vous se posent sûrement de nombreuses questions : qui sont les acteurs ? quand ? que cela va-t-il changer ? quelles sont les technologies qui se cachent derrière le terme "5G" ?

Au cours de cette présentation, j'essayerais de répondre à ces questions. Nous parlerons notamment de 3GPP de mmWave, NFV, 5G-New Radio, Massive IoT, LPWAN, ou de beamforming.

    everything @alexis0duque
  2. 2 HELLO! I am Alexis Duque Director of Research at

    Rtone PhD @alexis0duque alexisd@rtone.fr rtone.fr
  3. 3GPP IoT Edge 3 5G Beamforming Fog low latency Massive

    MIMO mmWave
  4. DISCLAIMERS 4 Mobile generations do not reflect technological evolution, marketing

    terms Mobile communications generations result from many evolutions and thus are not perfectly distinct Commercial, economical, and financial issues greatly influence the mobile technologies development
  5. WHO? 5 3GPP: groups of telecommunications standards associations, in Europe,

    Japan, USA ⇒ defines the standard NGMN: leading network operators organization, Verizon, O2, Telefonica, Orange, etc. 5GPPP: European initiative with industrial and institutional partners, Nokia, Ericsson, ...
