Who invented gprs

It is the first system which provides the worldwide mobile internet access. GPRS operates at an extremely slow speed. It downloads the data at the deficient range and even uploads the data at the range lower than the download range. Its features are as follows:. So, it is a special-purpose communication protocol. In this, the resources allocated when there is a need for data transferring, i. Toll road system.

UIC train control system. Weather information. Road traffic information. News, fleet management. Advantages of GPRS are as follows:. GPRS gives the speed of It can send data wherever and whenever the data is required. GPRS also allows for the transfer of the file. GPRS can remotely gain access for monitoring and controlling machines.

So these resources are charged accordingly. The disadvantages of GPRS are as follows:. Dinesh Thakur is a Freelance Writer who helps different clients from all over the globe. This service is compatible with 2G and 3G networks. For this the mobile phone or laptop must be connected to the GPRS network. GPRS technology is playing a vital role in the field of cellular network communication. It has a number of advantages for users and network operators over the GSM system as follow —. The GSM technology carries the voice calls and text messages, while the GPRS technology is used to transfer the data along with voice and text messages.

The GPRS is a best-effort service which implies variable through and latency that depend on the number of users sharing the service simultaneously. Using a traditional approach a circuit was switched permanently to a particular user. This is known as a circuit switched mode. In view of the "bursty" nature of data transfer it means that there are periods when it will not be carrying data. To improve the situation the overall capacity can be shared between several users.

To achieve this, the data is split into packets and tags inserted into the packet to provide the destination address. Packets from several sources can then be transmitted over the link. As it is unlikely that the data burst for different users will occur all at the same time, by sharing the overall resource in this fashion, the channel, or combined channels can be used far more efficiently. This approach is known as packet switching, and it is at the core of many cellular data systems, and in this case GPRS.

However upgrades are needed. The upgraded network, as described in later pages of this tutorial, has both the elements used for GSM as well as new entities that are used for the GPRS packet data service. In this way the investment required for GPRS would not be a one off investment used only on GPRS, it also formed the basis of the network for further developments.

To utilise GPRS new modes are required to enable it to transmit the data in the required format. With the incorporation of packet data into the network, this allowed far greater levels of functionality to be accessed by mobiles.

As a result a new breed of mobiles started to appear.
