19.3. Which advantages does GPSoverIP offer?
Many providers of telematics solutions use TCP/IP for the wireless transfer of GPS-data of
objects in motion in the Internet. TCP/IP is a universal and voluminous transport protocol
which actually was designed for a wired network. Its task is the general transmission of
data in the Internet, as for example texts, sound, photos, videos etc. For the transfer
of GPS-data of objects in motion to the mobile Internet it is, however, not absolutely
suitable.
This on the one hand is due to the size of its overhead, an extensive and data intensive
confirmation procedure, the transfer of unused layers (identification, flags, type of services,
version, varying overall length, checksum header, padding etc.), on the other hand the
varying bandwidth quality of the network providers in the mobile Internet also represents
a big hurdle for the TCP/IP transport protocol.
GPSoverIP, a modern protocol which was developed for the transfer of GPS and user data
to the mobile Internet, could successfully counteract the problems caused by TCP/IP.
GPSoverIP does not contain any unused layers, and is including GPS and user data
(longitude, latitude, direction, height, delivery time, speed, number of satellites, checksum,
as well as backup and user data) a multiple smaller than a standard TCP/IP package
without any data.
Therefore GPSoverIP works in a stable way even with varying bandwidth quality (=field
strength) unlike TCP/IP. Furthermore GPSoverIP renounces the overloaded headers and
works with an own confirmation procedure. The optimal header responsible for a fast
and secure transfer (=minimal) is reached if the GPS frame requires only one package.
This is the case with GPSoverIP.
In summary the advantages of GPSoverIP are quite obvious:
• Using GPSoverIP is safe, flexible, future orientated and powerful.
