I haven't been on the forum for quite a while and was very interested in seeing the WiFi topic being discussed.
Three of us MBCR Communications Department Technicians installed the WiFi in half a dozen coaches in the Worcester layover in early December as part of an undisclosed pilot program. I think they picked the Worcester line, quite frankly, because Lt. Gov.Tim Murray rides the line a least one day a week and he probably got to take it for a test drive before it's general release to the public (politics!). The Parvus equipment definitely outperformed the other WiFi equipment evaluated.
Using the coaches we did as installation templates (we did at least one coach of each model), the MBTA has subbed out the continued installation of WiFi equipment to a contractor (not MBCR) which is installing now at the CRMF.
Their initial goal is to get at least one car per set equipped and then install it in each coach. Our initial testing seemed to indicate that even if only one coach per set was hot spot equipped, that the adjacent cars, if not the entire set, had adequate coverage.
