Extreme Mobile Broadband
Massive Critical machine machine communication communication • 10 Gbps network speeds • Extremely low latency • New applications based on massive broadband capabilities
24 LTE technology for mission-critical voice • LTE is intrinsic part for 5G introduction • LTE as such already provides support for 5G concepts like IOT support (with LTE-M, NB-IOT, cloudification of core and radio) Train control • 5G focus initially on high + 5G for non-critical massive broadband density deployments (6GHz up to 30/60/60 GHz) • 5G to rely on OFDM Station Depot technology as well -> we are talking about evolution of Shared deployment radio, not revolution. (network slicing) Especially for low band (e.g. MiMo like LTE)
