Well, I doubt the radio has any service intelligence. It's just a
conduit. Depending on why two devices on the same radio have to
communicate, a cleverer system deep in the core would need to
process that before handing it back to the radio network.<br>
<br>
Of course, it makes the case for deploying services at each base
station to localize services, but that could get expensive for an
entire radio network, particularly within a 100km Metro where fibre
latency will remain at ±1ms anyway.<br>
<br>
Not to mention that with the exception of things like cars in a
traffic jam or on the same piece of highway, the chances of two
devices talking to each other over the same radio can't always be
guaranteed.<br>

I look forward to seeing this.<br>

The video won't play. Could be my browser.<br>

Anyway, time will tell. I see 5G roll-out density like rolling out
fibre in places only where the postal service can get to. But I hope
I'm wrong.<br>
