Comcast gets more aggressive with mobile as it bumps broadband speeds

Comcast has pushed ahead with a new mobile offering aimed at customers who take one of the operator's higher-end home broadband speed tiers. Comcast combined that announcement with a wave of free speed upgrades—including faster upstream speeds—across its prepaid and postpaid home broadband services. On the mobile end, Comcast is now offering new and existing home broadband customers an unlimited line of Xfinity mobile for a year when they subscribe to broadband speeds of 400 Mbit/s or faster. Those lines typically cost $40 per month. Comcast's mobile service comes with WiFi PowerBoost, a relatively new feature that enables Xfinity Mobile phones to get 1-Gig speeds when they are connected to a Comcast Wi-Fi access point. The new mobile promotion comes after executives hinted that Comcast would soon launch a lineup of new, simplified home broadband/mobile packages in its upgraded cable markets.
