Plans have been submitted to bring 5G technology to Radstock.
The application from mobile network EE is the first since its bid to upgrade a mast in Bath was rejected.
More than 300 people objected, including city MP Wera Hobhouse, with many citing health concerns. The government insists that 5G is safe.
Refusing permission for that scheme, planning bosses said the upgraded mast, some five metres taller than the current one, was inappropriate in the green belt.
The plans to upgrade the equipment at the Gasex Centre in Frome Road in Radstock will not face the same issue as the antennae would not be as high as a tower on the site, although it is a more urban area.
The application says: “The proposed replacement equipment will not only service voice calls but will include provision for 3G, 4G and 5G data use which will be of great benefit to all users (EE and H3G [known as Three]) of the networks.
“In addition to this, EE have been awarded the contract to provide network services to the emergency services, which will operate over EE’s 5G network and as such, this site will also provide coverage for all the blue light services in this area.
“There are no other, viable alternatives in the area which can be upgraded to meet the specific technical requirement for providing 5G network coverage to the surrounding area.
“Any harm will be minimal and would be significantly outweighed by the social and economic benefits and should be supported by Bath and North East Somerset Council without delay.”
Opponents of the Charlcombe Lane mast upgrade disputed the safety of 5G and raised fears about nearby residents and wildlife.
Cabinet member and Bathavon North ward member Sarah Warren told the planning committee in December: “All the 343 residents who have objected are asking for is not to be used as guinea pigs in a global experiment.
“We don’t need 5G. The only people benefiting from this development are the big technology companies. Please put our residents’ health first.”
The new application says: “A great deal of research has been undertaken throughout the world into the effects of electromagnetic radiation and radio signals and to date there has been no evidence to indicate that the systems so far operated and those intended to be operated have caused any manifest adverse health effects.”
B&NES Council will decide the fate of the application.
