F1's governing body, the FIA, earlier this week announced that messages relating to performance, including the status of fuel saving and power unit settings, are prohibited.
The paddock will still be able to communicate pit strategy and time differences to other cars, but for the most part drivers will be in charge of their own destiny in the car.
The rule change will come into play at this weekend's Singapore Grand Prix, but two-time F1 champion Alonso does not foresee any problems.
"[There will be] no big difference to be honest," he said. "It's not going to have a huge impact in the race itself or the weekend preparations, at least in our case.
"We've never used the radio for any performance reasons or something like that. Just to control temperatures, to talk about traffic or decide strategies.
"In our case it won't have a big impact; other teams, I don't know how exactly they use the radio, for what purpose.
"You can talk with your players if you're a coach in football or basketball. But at the end it's the player that shoots the ball - or the driver that drives the car.
"Some recommendations or whatever won't change the driving style."
Team-mate Kimi Raikkonen did voice some concerns on the change, though, saying: "It might get quite complicated if there are some problems with the car and you have to change certain things to try to finish the race.
"I don't know how the rule goes on those [aspects], obviously it makes it more complicated for us, but it's part of the game."
