Open 1. Why do I have to pay for it?
Contrasted with off-line tracking systems, nyomkovetes.net provides on-line connection between a vehicle and the server.
The SIM card placed in the device provides ON-LINE connection via GPRS and SMS connection. Consequently, with on-line systems such as nyomkovetes.net, you need to pay a monthly service fee for services.
Open 2. What is on-line or real-time tracking?
When you use an on-line tracking system such as nyomkovetes.net, the central unit placed in the vehicle will send position data to the server in real-time. The SIM card in the device sends data to the central server via GPRS connection.
Opposed to this, when you use off-line tracking systems, the central unit is not in connection with the central server. In this case data is generally collected on a memory card, and the GPS device needs to be disassembled in order to remove the memory card each time data need to be retrieved. Data stored on the memory card need to be uploaded on to a map software subsequently. These devices can usually be operated without paying a monthly service fee, but they don’t make it possible to track vehicles in real time.
Open 3. What is GPRS?
GPRS is a packet-oriented, IP-based mobile data transfer technology.
GPRS (General Packet Radio Service) is a packet-oriented, IP-based mobile data transfer technology used by GSM and IS-136 mobile phones. GPRS data transfer is invoiced on the basis of the volume of data (kilobytes) contrasted with mobile phone bills based on the minutes (that disregard whether there was any data transfer or the user was in a stand-by mode). In addition to WAP, SMS and MMS, internet use including e-mailing are part of the application field. Low-cost, IP-based telephoning is expected to be integrated into mobile phones in the future.
Generation 2 (2G) mobile devices with GPRS are often described as 2.5G, because their standards are somewhere between 2G and 3G mobile telephony. They provide moderate speed (in theory maximum: 171.2 kbps) data transfer by utilising unused TDMA channels in the GSM network. This speed is below what latest technological development can offer. They were originally developed to replace other standards, but these were replaced by GSM, and so they are only used in GSM-networks. GPRS is integrated into GSM standards releases starting with Release 97. Initially standardisation was done by ETSI, now by 3GPP.
Open 4. What is GPS-based positioning?
GPS is a global navigation system of satellites developed, launched and maintained on commission of the US Defence Department. With the help of GPS, we can determine our position anytime, at any point of the Earth with approximately 5 to 10 metres of accuracy.
GPS (Global Positioning System) is an advanced navigation system that enables us to do 3D positioning as well as to measure time and speed on land, air or water. Its accuracy ranges within metres, however, even millimetre-accuracy can be achieved by differential measurement methods – in reral-time. GPS, like many other technologies, was initially developed for military purposes. Today GPS is widely used for the most various civilian purposes. Using the data this small device provides, we can greatly benefit from a wide range of services that enhance our feeling of comfort, security and safety.
