live broadcasts of video without requiring wireless networks.
Do the writers know what a broadcast is and what wireless means?
I mean… it’s not a network technically. it’s a broadcast station (though the stations themselves are networks)
It still requires being in range of a (network of) wireless transmitter(s). I’d have written ‘without mobile networks’ or ‘cellular networks’ or ‘data connection’ or ‘IP networks’ as it’s a broadcast and not a two-way communication.
Sure, it’s nitpicking and they’re technically correct but it’s also imprecise wording. It’s still wireless transmissions and not magic.
ATSC 3.0 is just a scheme to turn free, over the air TV into another cable. Ever increasing prices.
It’s certainly beginning to look that way. DRM ruins everything.
Interesting. Why do they even want this technology on all phones?
I haven’t been following the issue, but:
The government believes mandating ATSC 3.0 in smartphones will help bring down network congestion in wireless networks.
So, over-the-air television uses broadcasting. You broadcast one signal, everyone in the area can receive it. You can have one viewer or a million viewers and it takes the same amount of bandwidth.
But if everyone is streaming video unicast, the way they typically would over the Internet from somewhere like YouTube – which has the benefit of letting people watch whatever they want, whenever they want, independent of anyone else, you can’t do that; you can’t have a million viewers in a cell, or anything approaching that, because bandwidth consumption scales linearly with the number of viewers.
I know that the US emergency alert system uses broadcasting over the cell network, so there has to be at least limited support for broadcasting in the cell network, though. I dunno if cell providers use it for pushing out system updates to phones, but if they don’t, I suspect that they should.

5G multicast-broadcast for group communication: Why it matters and how it works
Through 5G NR multicast-broadcast functionality, 5G networks can now be equipped to support efficient, reliable and scalable group communication services. Below, we explore the 3GPP technologies bringing high-performance connectivity to mission critical use cases.
It sounds like there is some kind of way to do broadcast/multicast within 5G, though.
