An upgraded WiFi system is set to expand coverage to all MBTA commuter rail lines, ferry boats and three of Boston’s busiest stations. But T-riders might have to wait until early-2016 to enjoy it.

MBTA General Manager Bev Scott dotted the line of a 22-year licensing agreement with inMOTION Wireless, Inc Thursday morning. Under the agreement, inMOTION will install a new $5.6 million WiFi system across all 14 commuter rail lines and extend connectivity to commuter boats and South, North and Back Bay Stations.

“This is a very exciting time for our Commuter Rail system,” said Scott in statement. “While the introduction of new locomotives and new coaches will continue to improve on-time performance rates, customer service initiatives like WiFi and eTicketing make the overall commuting experience an even better one.”

Installation work is expected to start this fall, and the full system is expected to go live within 18 months time. inMOTION Wireless will cover the entire bill, leaving the T and its customers off the hook.

inMOTION Wireless will install, operate and maintain the WiFi network on all passenger coaches and ferry boats. When activated, T-riders will have access to free WiFi and a live television feed. For $15 per month, T-riders will be able access a premium WiFi service, which will allow for data and video streaming.

The new agreement stipulates the T receive 7.5 percent of net revenue collected from the WiFi program.
