A total of 3,225 households have suffered digital TV interference from 4G services in the 800MHz spectrum range, according to new data.
The number was revealed at the most recent meeting of the 4G/TV Coexistence Oversight Board which brings together the government, mobile companies, at800 and Ofcom.
The problem is caused by the 800MHz band used to deliver 4G services interfering with the 700MHz band used for digital TV.
Installers from at800 have visited 11,243 homes in the UK where people believe they may have had a problem. The organisation has also fielded over 220,000 calls to its contact centre.
Ben Roome, CEO of at800, told V3 that the figures give the organisation confidence that the number of affected homes is likely to be far lower than the previous top-end estimate of 90,000.
"Concerns about mass interference have fallen by the wayside. We are going to see fewer than 90,000 [affected]," he said.
"There can be issues when one of these masts goes on nearby, but the good thing is that the Freeview platform appears to be more resilient to adjacent spectrum that previously thought."
Roome also said that sending postcards alerting people to an impending mobile 4G switch-on, and the potential problems it could cause, had also proved successful.
The at800 report revealed that one operator failed to inform at800 of the switch-on of services during the Ryder Cup golf tournament in Scotland, which left those in the area facing disruption without knowing why.
This meant that at800 had to respond rapidly by sending 5,031 letters to residents in the location.
"At800 had not been made aware in advance that 20 of those  masts were due for activation and had not therefore conducted its usual obligatory operation to mail households at risk of 4G interference to their digital TV service," it said.
The report added that Ofcom will write to the operators to remind them of their obligation to inform at800 of any network rollouts.
