olivia lambo says that the detectives just used 6 data points from
john okeefes cellphone - with accuracys from 30 meters to 60 meters -
to state that okeefe did not enter the home at 34 fairview rd

its only about 30 feet from the street to the front door of the home -
and 30 meters is equivalent to 120 geet - so it seems to me that the
cellphone data might be very misleading

one would expect that the lats/longs from the cellphone in the car
would be less reliable by a longshot than the cellphone long lats when
being carried between the car and the home - access to towers and
satellites should be much easier in the open than when within a motor
vehicle - one would think

anyone have better info on this?

didnt I post a followup on this? maybe not

1. the accuracy of john okeefes phone seemed to be mostly 10 feet
while enroute to 34 fairview - unknown what the exact lats longs were
- data was appended maybe - we did not see that data

2. john okeefe phone apparently was sending location data once every second

3. john okeefe phone lost accuracy for approx 6 pings and then stopped moving

we were thinking that maybe john okeefe threw his phone at karen read
suv - hit the taillight and broke the taillight- and then the phone
bounced onto the lawn - john okeefe then went inside 34 fairview and
was beaten to death - or maybe someone met john okeefe at the door of
34 fairview - took his phone from him - and threw it onto the lawn

here is my explanation of "accuracy" - definitions - infrastructure =
celltowers and satellites and computers and internet that links it all
together - apparently the cell towers send out a signal every second
to a cellphone - the cellphone plots its location via gps and sends
that location to the cell tower - the cellphone might also plot its
location by comparing the signal from multi cell towers - when the
celltower receives the return reply from the cellphone with the lats
and longs - the infrastructure can calculate the difference between
where the phone says it is based on gps or tower - and where the
infrastructure detects it to be (based on multi delays to receive the
signal on multi cell towers) - yes its complicated

let me try to find that report by ?gauarino? again

keep in mind - the cellphone has a much 'harder' time seeing the
celltowers and gps satellites when inside a car - or in a house - or
when under heavy tres - or in a snowstorm - etc - the signals mostly
travel in straight lines - and the signals are weakened / attenuated
by heavy objects and metal objects

you can search the internet for the terms - land mobile radio and emf
and radio wave propagation

this is all based on some document that we were viewing - unknown how
reliable the info is - apparently the data was from a msp detective -
maybe guarino

you can also look up info about 'triangulation' and the 'osborne range
finder' (which the forest fire tower guys use to figure out where
forest fires are at)

here is the report that mentions 10 foot accuracy of john okeefes
cellphone and 1 second pings -
