This data set contains 6 months of mobile phone records of German Green party
politician Malte Spitz, stored by Deutsche Telekom in 2009-2010.

This dataset contains records of all communications of a mobile phone serviced 
by Deutsche Telekom. Whenever the phone made a call or a connection, a 
timestamped record of the phone's location, service used, source, and 
destination was saved by the service provider. The phone's location was most
likely estimated by the strength of the signal received at the cell towers.

The owner of the phone travelled quite extensively during the data collection
period.

The phone was serviced by Deutsche Telekom's T-Mobile.

The data was collected by Deutsche Telekom from Spitz's mobile phone over a
half-year period.

This traceset contains 6 months of mobile phone records of German Green party
politician Malte Spitz, stored by Deutsche Telekom in 2009-2010.

Timestamped location data for every call or connection made by the cellphone 
was recorded by the service provider. Location was most likely estimated by 
the strength of the signals received by the cell towers.

In each pair of cell id A and cell id B, the id corresponding to the party
communicating with Spitz's cellphone was redacted by Zeit Online, replaced by 
XXXXXXXXXX .

The phone was turned off and not sending data for some of the time. Also, for
some reason, some of the coordinates and directions are unavailable.

There are numerous gaps in the records where the cellphone was turned off or
otherwise not able to communicate.

As far as we can tell, the location data was estimated based on data provided
by the cell towers, not obtained through GPS. Therefore, it is likely to be 
less accurate than GPS data.

This trace contains 6 months of mobile phone records of German Green party
politician Malte Spitz, stored by Deutsche Telekom in 2009-2010.

Call and connection records were collected by the phone company. Location data
for each record was most likely estimated by the strength of the signals 
received by cell towers.

This is a .csv file. The first line of the file lists field names and source 
URL. The other lines correspond to one connection record each.

The fields are:

- start time, end time (for some records), service, 
  incoming/outgoing (eingehend/ausgehend), longitude, latitude, 
  direction (in degrees), cell id A, cell id B

We believe that either the cell id A (for outgoing) or cell id B (for incoming)
corresponds to the base transceiver station communicating with Malte Spitz's 
cellphone. (The second id in every pair has been redacted, and we have no
information on what exactly the original entries used to contain.)

In each pair of cell id A and cell id B, the id corresponding to the party
communicating with Spitz's cellphone was redacted by Zeit Online, replaced by 
XXXXXXXXXX .

Numerous records are missing coordinates and direction; some are also missing
the service type.

The phone was turned off and not sending data for some of the time. Also, for
some reason, some of the coordinates and directions are unavailable.
