Our summary
Trends & Drivers in Wireless Technology Advancements
• 2G, 3G, LTE and 4G mostly defined by their Air Interface
• FCC’s generation definition: waveform & frequency
• Future generations: service, infrastructure and user prospects
• Use any frequency band and any RAT (DSA and cognitive network)
•HetNet = fusion of multitude complex technologies & topologies
• Co-operative and intelligent network
•Space: the next frontier
• Large scale, dense and flexible ’elastic’ system’
• Network management (system orchestration) will be the key
•New and advanced KQIs and KPIs
• System centric design, but physical layer (air interface) is NOT dead
