Mediacom Business, a division of Mediacom Communications Corp., will begin offering a scalable, high-capacity broadband network to hundreds of commercial properties in the Greater Des Moines area. Dubbed Project Open Road, the effort to put gigabit Internet speeds within immediate reach of more local businesses is part of a plan to invest $1 billion over the next three years expanding its national broadband network. Mediacom Business will build its advanced broadband facilities to the doorstep of commercial properties that have been in unserved or underserved areas. Over the next six months, the division will be approaching property owners to request rights of entry to wire the locations.
