| What is telematics ?
SeaKey, LLC makes the emerging
telematics technology available to boaters through our SeaKey®
products, including SeaKey® v2.0.
By the most basic definition,
telematics is the combination of a wireless communication system (i.e.
cellular, satellite, etc) and an onboard computer processor. Telematics
has been used primarily for commercial applications for monitoring,
tracking and reporting. One of the most widely known consumer
telematics systems is OnStar® , which is installed on many new
automobiles.
SeaKey® monitors the boat position
and status, and reports alarms to the Response Center, to the boat
owner’s email address, and to the boat owner’s personal
SeaKey® website.
Satellites ?
Satellites
are used for both positioning information and communications. The
SeaKey® system comes with a GPS receiver, similar to the one you
may use for your navigation system. Because the SeaKey® system is
always on, we only use the position data from our GPS, as most
navigation systems are turned off when you leave the boat.
For communications, SeaKey® v2.0 uses the ORBCOMM®
network of low-earth orbiting satellites. ORBCOMM operates thirty
satellites in six orbital planes that provide worldwide coverage. This
allows you to track your boat any where in the world it may be.
GSM ?
GSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity. GSM networks operate in four different frequency ranges.
Most GSM networks operate in the 900 MHz or 1800 MHz bands. Some
countries in the Americas (including Canada and the United States) use
the 850 MHz and 1900 MHz bands because the 900 and 1800 MHz frequency
bands were already allocated.
GPRS ?
General Packet Radio Service (GPRS) is a packet oriented Mobile Data Service available to users of Global System for Mobile Communications (GSM) and IS-136 mobile phones. It provides data rates from 56 up to 114 kbit/s.
GPRS can be used for services such as Wireless Application Protocol (WAP) access, Short Message Service (SMS), Multimedia Messaging Service (MMS), and for Internet communication services such as email and World Wide Web access.
Roaming ?
Roaming is a general term in wireless telecommunications
that refers to the extending of connectivity service in a location that
is different from the home location where the service was registered.
The term "roaming" originates from the GSM (Global System for Mobile Communications) sphere. Traditional GSM Roaming is defined (cf. GSM Association Permanent Reference Document AA.39) as the ability for a cellular
customer to automatically make and receive voice calls, send and
receive data, or access other services, including home data services,
when travelling outside the geographical coverage area of the home network,
by means of using a visited network. This can be done by using a
communication terminal or else just by using the subscriber identity in
the visited network. Roaming is technically supported by mobility
management, authentication, authorization and billing procedures.
