DETROIT — AT&T Inc. announced it had upgraded its wireless network within eight counties in Michigan. The improvements include adding greater capacity or bandwidth and speeds to 129 cell towers within Oakland, Macomb, Wayne, St. Clair, Genesee, Livingston, Lapeer and Washtenaw counties.
The bandwidth upgrades took place between August and November and will be noticed in many cities, including 30 sites on multiple locations in Wayne County cities, such as Allen Park, Canton Township, Garden City, and Romulus. Upgrades in St. Clair County include St. Clair and Port Huron. In Oakland, coverage improved on nearly 40 sites, spanning communities such as White Lake, Southfield, Farmington, Royal Oak and Pontiac. Nearly 30 Macomb County upgrades were made throughout communities such as Clinton and Macomb townships, Warren, Utica and New Baltimore.
Upgrades in Ann Arbor, Dexter and Ypsilanti round out improvements in Washtenaw County. In Livingston County, a site bordering Brighton and Howell, and one in Whitmore Lake, received a network upgrade. Attica, Almont and Imlay City in Lapeer County and Flint and Swartz Creek in Genesee County round out the areas of improvement.
Last month AT&T announced improvements on 140 sites in Michigan.
The company said the upgrades are like adding more lanes to a highway, meaning the result should be higher speeds for mobile data and more reliable phone service.
