TECHNICAL INFO & FAQ

*What is vehicle tracking system?
A vehicle tracking system combines the installation of an electronic device in a vehicle, or fleet of vehicles, with purpose-designed computer software at least at one operational base to enable the owner or a third party to track the vehicle's location, collecting data in the process from the field and deliver it to the base of operation. Modern vehicle tracking systems commonly use GPS or GLONASS technology for locating the vehicle, but other types of automatic vehicle location technology can also be used. Vehicle information can be viewed on electronic maps via the Internet or specialized software. Urban public transit authorities are an increasingly common user of vehicle tracking systems, particularly in large cities.

*What does SMS mean?
SMS - Short Message Service (a text message). Cellstop is currently the only supplier of direct communication between the vehicle and the client in real time via SMS. Cellstop's unit will change into GPRS mode when MTC coverage is lost, resuming MTC communication again when GPRS coverage is resumed.

*What is panic button of MDT?

*What is satellite tracking with advanced GPS and GSM/GPRS technology?

It means you know the exact location and status of your vehicle 24/7.

*What does MDT mean?
A mobile data terminal (MDT) is a computerized device used in public transit vehicles, taxicabs, courier vehicles, service trucks, commercial trucking fleets, military logistics, fishing fleets, warehouse inventory control, and emergency vehicles to communicate with a central dispatch office. They are also used to display mapping and information relevant to the tasks and actions performed by the vehicle such as CAD drawings, diagrams & safety information.

*What does VMS mean?
Vehicle Management System, being the server that houses the database of vehicle information and all the vehicles report to.

*What does GPRS mean?

General Packet Radio Service: standardised as part of GSM Phase 2+, GPRS represents the first implementation of packet switching within GSM, which is a circuit switched technology. GPRS offers theoretical data speeds of up to 115kbit/s using multislot techniques. GPRS is an essential precursor for 3G as it introduces the packet switched core required for UMTS. Because GPRS is charged out as a price per MB of data per month, GPRS can offer attractive cost savings to clients who have a requirement for higher frequencies of communications with their vehicles.

*What does GPS mean?
Global Positioning System: a location system based on a constellation of US Department of Defence satellites. Depending on the number of satellites visible to the user can provide accuracies down to tens of metres. Now being incorporated as a key feature in an increasing number of handsets.

*What does GSM mean?
Global System for Mobile communications, the second generation digital technology originally developed for Europe but which now has in excess of 71 per cent of the world market. Initially developed for operation in the 900MHz band and subsequently modified for the 850, 1800 and 1900MHz bands. GSM originally stood for Groupe Speciale Mobile, the CEPT committee which began the GSM standardisation process. GPS (Ground Positioning Satellite) technology will pinpoint your vehicle location, within 5 meters.

*What does LAN mean?

Local Area Network.

*What does SIM mean?
Subscriber Identity Module: A smart card containing the telephone number of the subscriber, encoded network identification details, the PIN and other user data such as the phone book. A user’s SIM card can be moved from phone to phone as it contains all the key information required to activate the phone.

*What does DSLR mean?
Digital single-lens reflex cameras (also named digital SLR or DSLR) are digital cameras combining the parts of a single-lens reflex camera (SLR) and a digital camera back, replacing the photographic film. Features like live preview, HD video recording with contrast detection autofocus or ergonomic integration like dedicated film speed (ISO) buttons took further advantage of the digital image sensor. Although the term DSLR often refers to cameras that resemble 35 mm format cameras, some medium format cameras are also DSLRs.
