TCP / UDP
TCP – Is a transport protocol used for
A protocol is the special set of rules that end points in a telecommunication connection use when they communicate. Protocols specify interactions between the communicating entities.
For Syrus it refers to TAIP Protocol.
Webservices refers to the Pegasus Gateay interaction via an API of communication.
API and all relevant information can be found in your Pegasus demo or actual site.
Virtual Private Network – basically it is assigned by the network operator – (cell phone provider for the SIMs) and it is a method of accessing a network (any host IP address ) without having access to the internet.
A server is a system (software and hardware) that responds to requests across a computer network to provide, or help to provide, a network service. In our industry it usually refers to any endpoint system (software and computer) where AVL devices report to.
Technically a gateway is a term used to link two programs acting as a portal where information can be shared.
In our case, we refer to the Pegasus as a Gateway because it has Webservices intergrated that allow communication with any host software, servers.
Gateway is also a term used to refer to a server where you can visualize AVL devices,
A term used for an online software, typically a server where you can visualize AVL devices.
Also see server.
Pegasus Gateway is a web tracking platform that is developed and owned by DCT. It is exclusively for the Syrus GPS devices and will include all the peripherals/accessories DCT manufactures.
This Gateway is more than a platform because it offers real time data from the devices that are connected via Webservices JSON RPC. This data is first transmitted to DCT, then it is sent to the client’s listener. The listener will receive the data parsed to avoid confusion. For more information please visit Pegasus Gateway.
GSM stands for Global System for Mobile Communications – it is an international standard that basically allows your Syrus device to maintain a voice connection or SMS connection with the Syrus device.
GPRS stands for General Packet Radio Service, in the most simplest of terms it refers to the Syrus’ connection to the internet via the SIM card. GPRS is GSM based, this means that it is an evolution from GSM technology, and as the name implies, it uses Packet Switching technology to transmit data.
When we talk about Syrus and mention GPRS we refer to having the communication channel available for the device to speak to the server/platform. If GPRS is down, this means that there is no internet connectivity on the device and this can happen if cell phone carriers do not provision the SIM correctly.
