And at that point, what if people then stop buying wired Internet lines and wireless routers (because they all get the same bits, anyway), and instead use the cell network that already surrounds them.
I don't think the telecom companies are going to be displaced very soon because the simplicity of never having to choose a network to connect to is just how people think. Continguous and unibiquitous mobile broadband is probably not on the horizon from someone who isn't a large telecom.
The move to unlocked phones though, I think is spot on.
Cell data server works mainly because they put up a HUGE number of towers. But on the flip side, because they put up a limited number of towers, and make sure to not interfere with themself by carefully adjusting the transmit power.
Can you please elaborate? I haven't seen any movements in this direction, in terms of wifi technology.
This will only happen when people stop locking WiFi access points. It's rare for me to be in an area with no WiFi at all (except for parks, and freeways), but they are almost always locked.
Is it true that if the WiFi is not locked then all the data is transmitted in the clear?
