In October 2009, Sprint announced
With the deployment of Network Vision to the rest of D.C. will they also bring Network Vision to the underground Metro stations that already have Sprint service at the same time? Also, at the same time will they be deploying Network Vision to underground Metro stations and tunnels that don’t have Sprint service yet?
If they do delay Network Vision deployment to the Metro system I would believe it would have to do with the additional planning, permits and coordination with multiple entities, required to work within the Metro System.
