800MHz Overbuild

Critical to public safety and continuity of government operations is the City’s 800MHz fiber ring, a 50-mile fiber loop around the City which provides important communications, and network connections to City government, public safety organizations, and community anchor institutions. The 800 MHz Overbuild project, completed in December 2015, expanded and improved Baltimore’s critical fiber infrastructure by deploying 31 additional miles of fiber, completing the fiber ring and providing increased redundancy and capacity.

This additional capacity will form for the foundation of Baltimore’s 21st century tech infrastructure. The additional capacity can be used to add “spurs” to bring broadband capability to any location within the City.  Schools, recreation centers, and other city facilities could have fiber optic high-speed broadband with only the expense of running fiber to the 800 MHZ ring which surrounds the city.  There is also the opportunity for public-private partnerships which could provide more information and resource sharing as well as revenue generating opportunities. MOIT is currently working with other government agencies and private partners to develop revenue sources, governance, public/private partnerships, and marketing strategies for the City’s broadband infrastructure.

800MHZ Overbuild Phases: All are complete

Fiber Overbuild Map

  • Phase One – Interconnect
    Phase One brings ICBN Fiber to the 800 MHZ Lombard Tower. A 96 count of single-mode fiber will be directionally bored to connect ICBN network and Lombard Tower.
  • Phase Two – Tower Connections
    A 96 count of single-mode fiber will be installed and spliced into key 800MHZ tower locations.
  • Phase Two – Curtis Bay to Edmondson High School
    156 count of single-mode fiber will be directionally bored adjacent to existing 800MHZ fiber from Curtis Bay location to St. Agnes Hospital. Fiber will then run to Edmondson High School. No splicing involved.
  • Phase Three – Edmondson High School to TV Hill
    156 count of single-mode fiber to be directionally bored adjacent to existing 800MHZ fiber from Edmondson High School to Kernan Hospital. Fiber will then run to Northwest Police District and then to TV Hill location. No splicing involved.
  • Phase Four – TV Hill to Lombard Tower
    156 count of single-mode fiber to be directionally bored adjacent to existing 800 MHZ fiber from TV Hill to Good Samaritan Hospital. Fiber will then run to Lake Clifton High School and then to Lombard Tower to complete the Overbuild. No splicing involved.
