Better than 30m accuracy for both indoor and outdoor positioning with cellular positioning.

GloPos has announced its software-only positioning technology that makes
all mobile phones location-aware - outdoors, indoors and even
underground. They have achieved better than 30m accuracy for both indoor
and outdoor positioning with cellular positioning, and almost ready for
commercial.

To me it just sounds too good to be true, since I think the current
generation of cellular network has no such capability. If they can do
it, there will be no need to integrate GPS into the consumer electronics
any more. I am not sure it is a marketing ploy.

Does anybody know more?

Thanks.

Underground, that would be a neat trick. Makes the credibility of any
of the claims suspect...

And it still would not replace GPS as there are Way Too Many places
with no cell reception at all, not to mention the over all crapy cell
reception in many more areas. But it could be a nice supplement - but
as pointed out seems t be bogus. Like those books and movies where
they use GPS in the Sewers of NYC or Seattle!!

Why, just the other day in my hole to China I used my GPS to figure
out how far it was to Peking... Problem! How do I figure out which
route it used for the computation?
