Director, Widenet Group Ltd
Brett Shaw received the B.E. and M.E. degrees in Electrical and Electronic Engineering from the University of Auckland in 1993 and 1995, respectively. Since then he has gained over 20 years of technical design experience working in New Zealand, Australia and the UK. He has worked on projects such as the rollout of digital terrestrial TV and the design of nationwide broadband wireless access networks. He recently worked as a design engineer for operators such as Vodafone NZ and 2-Degrees Mobile, where he designed both transmission backhaul networks with microwave radio and fibre, and also radio access networks with GSM and UMTS.
Brett’s academic interests include research on methods to allocate spectrum for cellular networks.
Research Workshop: Spectrum Management
Sunday, 17 January 2016
Our research summarises the benefits and limitations of using spectrum at mm wavelengths for radio access in cellular networks. It discusses the engineering viability of using mm wavelengths for cellular use, but focuses on the assignment of spectrum in this band from a regulation and policy use point of view. In particular, the analysis considers whether mm wavelength spectrum should be used as licensed or unlicensed bands, or a combination of both, when used for cellular networks.
Our research shows that mm wavelengths for cellular use is best used where coverage is not expected to be continuous or ubiquitous, and used in areas where capacity demands cannot be met by using the UHF band. In addition our paper shows that there are benefits of assigning part of the mm wavelength band as unlicensed spectrum for private individuals or small networks, and part of the adjacent mm wavelength band as licensed spectrum for cellular operators.
