Wireless technologies are steadily approaching Shannon limits. Network densification (reuse), unlocking swathes of new spectrum, and spatial multiplexing gains via multiple antennas are key to delivering higher network capacity. Enabling these concepts to coherently work together - while also achieving practical, lower cost networks - is itself a key challenge. Dr Barratt will share perspectives on technologies that enable more efficient use of spectrum and greater network capacity to support the future growth of the wireless Internet.
Craig Barratt is an industry leader in wireless technology and communications. He joined Google in 2013 and oversees Alphabet's Access division, which includes Google Fiber, the gigabit-speed internet service. The co-inventor of 34 US patents, Craig was previously President and CEO of Atheros, one of the semiconductor pioneers of Wi-Fi, where he led its public offering in 2004 and sale to Qualcomm for US$3.6 billion in 2011. Craig holds PhD and Masters degrees in electrical engineering from Stanford University, and B.Eng and B.Sc. degrees from the University of Sydney. He is co-author of a book on Linear Controller Design and several open source projects.
