Seems like Airtel started 5G testing all over India, I can see the 5G coverage in many places nearby in the Ookla's app.

Nothing like that is necessary wait for Airtel 5G launch they'll deploy 5G in less than 10 towers and advertise 5G in whole cityTo launch 5G, any operator needs to have 60-70% 5G enabled towers in a city
At the risk of bad press. This 10 tower 5G deployment strategy would have worked 6-7 years ago when people were not so tech savvy but now every mom and her dog knows 5G is coming and assume it to be better than 4G.Nothing like that is necessary wait for Airtel 5G launch they'll deploy 5G in less than 10 towers and advertise 5G in whole city
