If you're already down that route, why have your TVs connected to your WiFi at all?
That’s retail.
I have changed my mind on this: if you were selling a million televisions a month, you could absolutely make it work from a money standpoint. They don’t need to send back tons of data and they don’t need to do it particularly fast.
This should be pretty easy to implement on the telco side and it would let them monetize the dead time in the network, same as TOU pricing for electricity.
OTOH, perhaps it's simply a question of an insufficiently large addressable market for non-realtime data like this. Maybe there's room for an M2M-focused MVNO to negotiate a block of off-hours data for dirt cheap and offer this kind of service, maybe paired with some kind managed platform to handle the storage and transmission side.
You’d think ha. Economists have a term for this “deadweight loss”.
MVNO are probably the best place for this kind of dynamism but they are always limited by the tools that the tier 1 carriers give them.
There is stuff like you describe on the way but progress is glacial. You’ll get bits and pieces dripped out bit by bit as the big guys satisfy themselves they’re not missing out on anything.
Just a note that this was one of the puzzles Steve Jobs managed to crack. We had smart phones before the iPhones but progress was stymied by the industry - thankfully jobs recognised the potential and had the wherewithal to put the Telcos over his knee and make them his bitch.
Steve is gone now, and there aren’t too many players like that around now and you can see how gradually the smartphone market has started to tend back towards the more orthodox again.
