Optimising the Last Mile of 5G Wireless Networks

Communications technologies account for about 10 per cent of the world’s energy demands, and this is set to rise with 5G. So we need to come up with smarter ways to transmit signals between devices and base stations reliably with minimal amounts of energy. My research will enable this.”

In part 10 of our 2019 researcher case studies we look at Dr. Nam Tran of the UCD School of Electrical & Electronic Engineering.

Fifth-generation wireless networks, commonly known as 5G, seek to send data rapidly and reliably. To achieve this, a critical issue that needs to be resolved is the ‘last hop’ between users’ devices and the serving base stations. Specifically the connections in the last hop of a wireless network can suffer from severe interference, and it is expensive and inefficient to overcome that by allocating dedicated time slots or frequency bands to each device.
