Wrasse: Riding Millimetre Radio Waves at Gigabit-per-second Speeds

The number of mobile-connected devices is rapidly increasing and bandwidth-intensive applications with very-low latency requirements, such as ultra-high definition television (4K video), remote medical services and smart transportation systems, are expected to dominate the Internet traffic demand by 2020. To support such services, future 5th generation mobile (5G) networks will harness millimetre-wave radio frequencies. Ofcom has recently made available in the UK on a licence exempt basis a 6.8GHz width spectrum block in the 60GHz band, that is suitable for very-high speed short-range wireless systems.

Objectives

This project seeks to explore the potential of wireless networks that operate in the 60GHz frequency-band to achieve Gb/s data-rates. The problems we are currently investigating include 802.11ad performance analysis, resource allocation, and small cell backhauling. We are also interested in heterogeneous systems that combine millimetre-wave technology with traditional Wi-Fi operating in the 2.4 and 5GHz bands.

Experimentation

We are building a test bed using commercial off-the-shelf embedded computers equipped with wireless gigabit network interface cards, to facilitate prototype validation under a broad range of traffic conditions.
