CONCLUSIONS
OUTDOOR
Very good location accuracy, average radius 16,7 metres
High share of calls giving (correct) location
= very useful
INDOOR
Location or not depdending on type of building (concrete walls, thick roof),
Good location accuracy, average radius 29,9 metres= useful if/when location delivered
CONCLUSIONS
UNDERGROUND
More often than not, no location delivered
When delivered (in 38% of test calls), average radius 1164 metres
= still useful if/when delivered
SHOPPING MALLS
Location delivered in 42% of test cases, surprisingly low figure(?)
There should have been a higher degree of location deliverance with access of WiFithan it really did(?)
When delivered, average radius 33 metres= useful if/when location delivered
