About
A one-person practice with two decades behind it
Full Spectrum Intelligence Ltd. is the independent consulting practice of Greg White — a senior network architect specialising in enterprise Wi-Fi, RF, and network security. It has run alongside a full-time architecture career since 2016, focusing projects where specialized experience moves the needle.
Principal — Greg White
Greg has spent 20+ years designing wireless and enterprise networks for environments where the network is the event: multi-sport games, tech product launches, exhibition campuses, and service-provider infrastructure. The work spans predictive and validated RF design in high-density spaces, AAA / NAC and 802.1X architecture, and — more recently — defense-in-depth security and data-centre fabric design.
Most recent role: Senior Information Security & Enterprise Network Architect at a metropolitan fibre service provider, responsible for security and enterprise network architecture against regulatory and industry standards. Earlier roles there covered secure enterprise and wireless architecture across access, VPN and data-centre environments, and lead responsibility for a metropolitan public Wi-Fi network.
Selected career history: lead Wi-Fi architect for the Toronto 2015 Pan Am / Parapan Am Games (40+ venues on a unified WLAN and NAC design); Wi-Fi network design and advanced client-device troubleshooting at BlackBerry, including campus and global-office wireless across 100+ controllers and 3,000+ APs and the wireless behind the BB10 launch video-call demonstration; NAC and predictive Wi-Fi design for a national insurer’s downtown Toronto pre-construction project; and, through FSI, the multi-year Exhibition Place campus network engagement.
He was also first to identify a widespread buffer-overflow condition triggered by consumer multicast behaviour on a class of Wi-Fi chipsets that affected a majority of home consumer Wi-Fi.
