Research Group

Communications and Networks

The Communications and Networks group in the School of Computer Science and Electronic Engineering (CSEE)  is currently the biggest group of the School with 18 academics. 

The main focus of our group is the design of next generation wireless communication and network architectures and systems. Our academics have a wide expertise in wireless communications, physical layer communications, energy harvesting, networking, information-centric networking, optical networks, multimedia communications, machine learning for communications, channel coding, computer security, privacy, signal processing, and applied mathematics.

Our group has rich testbed infrastructure and comprises four laboratories: network convergence laboratory, access network laboratory, RF and microwave laboratory, and optoelectronics laboratory. Our academics are active with European Commission, EPSRC and Innovate UK funded projects.

Facilities

Access laboratory

Our Access Networks Laboratory has state-of-the-art wireless and system measurement tools. These include a top-of-the-range 100GHz sampling scope, a 40GHz real-time signal analyser, a 67GHz vector network analyser, a 40Gb/s data test-set and a 400Gb/s optical sampling head.

Network convergence laboratory

The Network Convergence Laboratory (NCL) maintains a well-equipped research network test bed that consists of electrical and optical core networking technologies and heterogeneous wireless access networking technologies across the University campus and surrounding areas.

In addition to hosting several planetLab nodes NCL is also connected to GENI in USA via openFlow switches. Facilities for software-defined networks (radio or wire) and sensor networks are also available in NCL, which are used in various EU and EPSRC projects.

Optoelectronics laboratory

Our Optoelectronics Laboratory houses:

  • lasers, detectors and optical components for optical spectroscopy of semiconductor devices from IR to UV wavelengths
  • various cryostats and kits for electronic transport measurements in semiconductor devices from T=1.3k to 300k
  • optical spectroscopy with 100 picosecond resolution
  • electronic transport measurement facility with 1ns time resolution and up-to electric fields of 250 kV/cm
  • a clean room
  • a micro-fabrication facility

RF and Microwave research laboratory

The RF & Microwave Research Laboratory enjoys modern equipment for developing devices and systems to 67 GHz, including several scalar and vector network analysers, signal sources, spectrum analysers with external mixers, power meters, an atomic force microscope, a probe-station with thermal control, a test fixture, mm-wave antenna radiation pattern measurement, as well as design workstations with ADS and CST software.

The equipment (which cost in excess of £500k) was mainly obtained through EPSRC grants and SRIF funding and has been used in research projects such as the EPSRC grant on Liquid Crystal Based Beam Steerable Planar Antennas for 60 GHz Wireless Networks and Full duplex radios.
