O’Sullivan has managed a number of integral projects during the past year, including Comcast’s Xfinity network and the deployment of more than 3 million hotspots. As far as she’s concerned, that’s just the beginning. Under her leadership, the network will reach 8 million hotspots by the end of this year, covering 19 of the country’s 30 largest cities with fast and wireless Internet access. O’Sullivan also managed the national rollout of Comcast’s Xfinity Internet speed increases in which Comcast doubled the speeds of its two fastest speed tiers, Blast! and Extreme 150, and increased the speed of the Performance Tier at no additional cost.
