5G Wireless | What is 5G?
• 5G, 5th generation mobile networks or 5th generation wireless systems, is a term used to describe the next generation of mobile communications technologies. The predicted availability is 2020.
• Currently still in the development phase, but we anticipate it to be. . .
More available bandwidth for consumers Lower network latency More network capacity

Team Size and Skills
Engineers should therefore be
equipped with the methods and
tools required to develop models
for managing this complexity

The Need to Prototype
Design Prototype Deployment
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 “
