Radio Broadcasting from Online Stream

Thank you for the warm welcome colporteur, yes I'm new to the community.

Greatly appreciate both of your comments and apologies for the lack of clarity. That question was overly simplified and vague.

It would certainly be amateur radio and I feared there could be some local law broadcast violations which I'd look into individually. 

In short, we often attend live sporting events where either there are no RF commentary broadcasts, (but there is online audio commentary available via an app) or there is an RF broadcast in a local language (and the English commentary is available via an app).

Where wifi is available at these events, the signal strength is often poor and it's heavily over subscribed. 4/5g connections are also unstable simply due to the number of mobile phones in the vicinity. Therefore the online audio commentary is inaccessible. 

In theory, I thought "perhaps" it was possible to acquire/configure a device that could take audio from a live online audio stream, and transmit it through a RF to a small group of receivers/headsets.

I appreciate there may be broadcast licences involved and local law also, but wanted to understand how complex this would be to setup.

Thanks again for your comments and quick responses.

Hi,

Unfortunately the amateur radio licenses explicitly forbid broadcasting. Any communication via amateur radio licence has to be licensed user to licensed user (apart from a request for a contact). However, there could be the possibility of licenses for events perhaps (but this wouldn't fall under amateur radio).

Some unlicensed methods of transmission are possible, but often they are low power, on specific bands. Low power isn't necessarily a problem especially with fixed installs, or if it is just going to be broadcast to nearby people. But it wouldn't be something receivable on broadcast frequencies (i.e. AM or FM broadcast bands), since that is not possible unlicensed (although some people do use devices that transmit at extremely low power, e.g. in cars to play music from their phones with the FM radio). That could be an option if it's just a small group of friends very close by at a show perhaps, since it would just use off-the-shelf equipment (a music FM sender, and a bunch of cheap FM receivers with headphones). 

However as baldengineer says, usually WiFi can be an excellent solution for events (there are some orgs which specifically advertise their WiFi installs in stadiums etc). 

Bring your own WiFi in your car.
