Key requirements towards 2020
Support up to 1000 times more traffic
Enable Gbps peak speeds
Reduce latency to milliseconds
Deliver safe superior customer experience
Make networks self-aware, self-adaptable, and intelligent
Improve energy efficiency
We cannot predict all the use cases so flexibility is a key requirement
Manage up to 10 times more users

System Requirements for B4G Local Area
• Always connected, 10Gbit/s peak data rate, 1ms RTT
• Support flexible deployment and new use cases
• Low cost, low power consumption
TDD is an attractive duplexing method
• Flexible UL/DL duplexing
• Fluent support of access, self-backhauling and D2D
• Low cost RF
• Reciprocity gains for MIMO
Component technology evolution is main enabler to allow low TDD latency
• E.g. fast switching
