What is the difference between GSM module and GSM modem?
A GSM module or GPRS modules are similar to modems, but there’s one difference: A GSM/GPRS Modem is an external equipment, whereas the GSM/GPRS module is a module that can be integrated within an equipment. It is an embedded piece of hardware.
What is the use of GPRS modem?
A GSM/GPRS Module is a device or chip that is actually responsible for the wireless communication with the GSM Network. A GSM/GPRS MODEM is device that modulates and demodulates the signals from the Wireless Network and allows internet connectivity.
What can you do with a GSM modem?
When a GSM modem is connected to a computer, this allows the computer to use the GSM modem to communicate over the mobile network. While these GSM modems are most frequently used to provide mobile internet connectivity, many of them can also be used for sending and receiving SMS and MMS messages.
Is GSM better than GPRS?
While considering the communication rates in both networks, GPRS offers cheap data charges than GSM. GSM allows only short messages for communication while GPRS has the provision of instant messages and email to send longer messages and to manage the services so that the charges are lesser when compared with the other.
What makes GPRS faster than GSM?
GPRS is an up-gradation of GSM features over the basic features to obtain much higher data speeds and simple wireless access to packet data networks than standard GSM. It is the standard-bearer of the 2.5G technologies. GPRS is a packet-switched network. In GPRS, billing is based on the amount of data transferred.
What are the advantages of GSM?
Advantages of GSM :
- More suitable network with robust features.
- No roaming charges on International calls.
- Worldwide connectivity and extensive coverage.
- SAIC and DAIC techniques used in GSM provide very high transmission quality.
Why is GSM used?
In the US, GSM operates in the bands 850 MHz and 1900 MHz. GSM owns a market share of more than 70 percent of the world’s digital cellular subscribers. GSM provides basic to advanced voice and data services including roaming service. Roaming is the ability to use your GSM phone number in another GSM network.
What is the purpose of GSM device?
A GSM modem or GSM module is a hardware device that uses GSM mobile telephone technology to provide a data link to a remote network. From the view of the mobile phone network, they are essentially identical to an ordinary mobile phone, including the need for a SIM to identify themselves to the network.
What is the advantage of GPRS over GSM?
An advantage of GPRS over GSM is that GPRS has a much higher data transmission speed. GPRS can be used as the bearer of SMS. If SMS over GPRS is used, an SMS transmission speed of about 30 SMS messages per minute may be achieved. This is much faster than SMS over GSM.
