Prototyping Is Critical for Breakthrough Research

“Experience shows that the real world often breaks some of the assumptions made in theoretical research, so testbeds are an important tool for evaluation under very realistic operating conditions”

“…development of a testbed that is able to test radical ideas in a complete, working system is crucial”

Massive MIMO in Cellular Networks

• Give basestation a large array of antennas

(> 10X higher than current systems)

• Time-division duplexing (TDD)

• Excess antennas guarantee good channel with high probability

• Large number of users can be served simultaneously

mmWave Technology for Mobile Access

• Existing cellular bands are crowded and expensive

• The next frontier is mmWave frequencies to provide

• High throughput (> 10 Gb/s)

• Lower latency (< 1ms)

• Enables “ultra-definition” media and “tactile” applications

• FCC recently proposed rules for 28, 37, 39, and 66-71 GHz for mobile access
