Gprs how does it work

The usual transmission volume in industrial communication, however, clearly remains below this critical volume, and is therefore ideal for using GPRS. Advantage 3: Parallelisation within the control station. Whereas in a control station many field devices used to be read out in parallel by means of conventional technology via modem racks, GPRS affords considerable simplifications. Only one Internet access for the control station is required, modem racks are dispensable.

Also connection establishment is considerably faster using GPRS rather than using conventional modem technology. Field devices are often required to allow the fastest possible readout. Here GPRS has a clear advantage over other technologies. Any prospective subscriber will pay attention to the basic charge and the included monthly volume in choosing a provider.

But just as important is the GPRS tarif unit. Since usually no connect times are billed in the GPRS network the billing is based on the amount of bytes transmitted. The billing unit used is the block size unit. In current contracts, block sizes of one kilobyte are most frequent, whereas previously block sizes of kilobytes were normal.

That means for the customer that always a complete block will be billed per dial-in into the GPRS network, even if the data transmitted is actually less.

With a block size of kByte, this may easily result in a high bill. Of course there are cases of applications in which GPRS is not the ideal choice for transmitting data. Our new website.

IT Security. Cellular Services. M2M Expertise Network. This is unsuitable for applications with bursty traffic. The user must pay for the entire airtime, even for idle periods when no packets are sent e. In contrast to this, with packet switched services, billing can be based on the amount of transmitted data. The advantage for the user is that he or she can be "online" over a long period of time but will be billed based on the transmitted data volume.
