Professor O’Farrell holds a Chair in Wireless Communication. His research activities encompass resource management as well as physical layer techniques for wireless communication systems focused on cellular mobile (WCDMA, HSPA, Femtocells, LTE, LTE-Advanced, 4G), wireless LAN (802.11a/g/n/ad) and wireless optical systems (IR, visible light). He has led over 18 major research projects as PI, supervised to completion 17 PG theses and published over 230 research outputs, including 8 granted patents. He has participated in standards, consultancies and expert witness activities in the wireless sector. Currently, Professor O’Farrell is the Academic Coordinator of the Green Radio project jointly funded by MobileVCE and EPSRC. He is a Chartered Engineer, a member of the IET and IEEE.
