AT&T Adds New Sites, Upgrades Network Across Maryland

4G LTE Expansion Will Give AT&T Customers and FirstNet Subscribers Better Access to Mobile Internet

AT&T* customers and FirstNet subscribers across Maryland got a big boost in wireless connectivity this year. We’ve added new cell sites across Maryland to enhance the state’s 4G LTE coverage and help give residents and first responders faster, more reliable wireless service. Our investment will help customers get the most out of their mobile devices.

The new sites include:

Hagerstown, Washington County, near North Burhans Blvd. and West Irvin Avenue

East New Market, Dorchester County, near Mount Holly Road and Fox Ridge Road

Edgewater, Anne Arundel County, near Central Ave and Pike Ridge Road

Frederick, Frederick County, near Reichs Ford Road and Public Safety Place

Hanover, Anne Arundel County, near Live! Casino in Arundel Mills 

Rockville, Montgomery County, near Shady Grove Road and W. Montgomery Avenue

Frederick, Frederick County, near the intersection of I-270 and I-70


These new sites are among an estimated 364 network upgrades we made in Maryland in 2019.

“We want our customers to have a great experience. With 4G LTE mobile broadband service, they’ll be able to experience better network connectivity while streaming videos, sharing on social media or texting family and friends,” said Denis Dunn, president, AT&T Maryland.  “We consistently work to provide better coverage for the community and its first responders, and we’re investing in our wireless network across Maryland to accomplish that.”

We know how important it is for our customers to stay connected. That’s why we’re also boosting network reliability and capacity as we expand our network. This helps Maryland residents get the best possible experience over the AT&T network wherever they live, work and play.

These upgrades will also benefit public safety and first responders on FirstNet – public safety’s dedicated communications platform. FirstNet is bringing public safety communications into the 21st century with new, innovative capabilities to help those users stay safe and save lives.

These enhancements also bring Band 14 spectrum to the area. Band 14 is nationwide, high-quality spectrum set aside by the government specifically for FirstNet. Its signal covers larger geographic areas with less infrastructure to better support rural communities, and it can better penetrate buildings and walls in more urban areas as compared to higher-MHz spectrum. When not in use by FirstNet subscribers, AT&T customers can enjoy Band 14’s added coverage and capacity.

FirstNet is being built with AT&T in a public private partnership with the First Responder Network Authority. It’s designed to help first responders in Maryland and across the country connect to the critical information they need – when they need it – so they can keep themselves and the communities they serve safer.

We’re committed to investing in our networks in Maryland.

From 2016 to 2018, we invested nearly $450 million in our Maryland wireless and wired networks. These investments boost reliability, coverage, speed and overall performance for residents and their businesses.
