Verizon on Wednesday lit up its 5G network in parts of four more cities: Atlanta, Detroit, Indianapolis, and Washington, D.C.

The move follows earlier rollouts in parts of Chicago, Denver, Minneapolis, Providence, and St. Paul for a current total of nine Verizon 5G mobility cities. At this point, only five devices work with Verizon's 5G Ultra Wideband network: the LG V50 ThinQ 5G, Motorola Moto Z3 and Z4 combined with the 5G moto mod, Samsung Galaxy S10 5G, and the Inseego MiFi M1000 hotspot. Verizon says that's "the most 5G devices available on any 5G network."

The company plans to have its 5G network up and running in parts of more than 30 cities by the end of the year, including Boston, Charlotte, Cincinnati, Cleveland, Columbus, Dallas, Des Moines, Houston, Kansas City, Little Rock, Memphis, Phoenix, San Diego, and Salt Lake City. We're tracking all of the carriers' 5G progress on our Race to 5G page.

"Verizon has an annoying habit of describing its coverage areas in words rather than releasing maps," PCMag's Lead Mobile Anayst Sascha Segan wrote following the company's 5G launches in Denver and Providence. That holds true for today's launches. PCMag is in the process of building those maps for today's launches, but that will take some time. In the meantime, here's where Verizon says its 5G service is available in these new cities:

Washington, D.C.: "areas of Foggy Bottom, Dupont Circle, Cardozo / U Street, Adams Morgan, Columbia Heights, Le Droit Park, Georgetown Waterfront, Judiciary Square, Shaw, Eckington, NOMA, National Mall and the Smithsonian, Gallery Place / Chinatown, Mt. Vernon Square, Downtown, Penn Quarter, Brentwood, Southwest Waterfront, Navy Yard, and nearby Crystal City, VA, as well as around landmarks such as the Ronald Reagan National Airport, United States Botanical Gardens, Hart Senate Building, National Gallery of Art, Lafayette Square, The White House, Freedom Plaza, Farragut Square, George Washington University, Capital One Arena, Union Station, Howard University Hospital, George Washington University Hospital, and Georgetown Waterfront Park."

Atlanta: parts of "Downtown, Midtown, Tech Square, and around such landmarks as The Fox Theater, Emory University Hospital Midtown, Mercedes Benz Stadium, Home Depot Backyard, Centennial Olympic Park, Georgia Aquarium, World of Coca Cola, and parts of Renaissance Park."

Detroit: parts of "Dearborn, Livonia, and Troy, including areas around the Oakland-Troy Airport."

Indianapolis: parts of "Arsenal Heights, Bates Hendricks, Castleton, Crown Hill, Fountain Square, Grace Tuxedo Park, Hawthorne, Historic Meridian Park, Lockerbie Square, Ransom Place, Renaissance Place, St. Joseph Historic Neighborhood, Upper Canal and Woodruff Place and around such landmarks and public spaces as Garfield Park, and Indiana University School of Medicine."

PCMag's Segan recently tested Verizon's 5G network in Chicago using a Samsung Galaxy S10 5G and got great speeds where obstacles like trees and buildings didn't cause signal drops.

"I got speeds up to 1.17Gbps with a clear line of sight to a cell site 500 feet away," he wrote. "But millimeter-wave technology is still extremely finicky and deals poorly with obstacles, which will be a big obstacle as Verizon and AT&T try to extend their coverage over broader areas."
