Wireless Master

GPRS has certain technical aspects and the only network within which GPRS is active is the GSM networks. Basically, the crux of the matter remains that the technology of GPRS extends or rather, enhances the facilities and the services of the GSM networks and hence makes certain services possible.

Firstly, GPRS provides what is known as “always on” Internet services. This implies constant as well as instant connectivity to the internet at all times.

Secondly, the Multimedia Messaging Service or MMS is activated. Through this feature, one can send picture messages and even video messages for that matter.

Thirdly, there is the Push to Talk facility.

Fourthly, there is the Instant messaging feature.

WAP or Wireless Application Protocol is enabled. This means that gadgets like the smartphones can always have a steady internet connectivity.

Lastly, there are provisions for the Point to Point or the P2P service. This basically means that users can directly access each other over the Internet.

We all send a lot of text messages to people we know, using the Short Messaging Service or the SMS on our phones. We usually use the GSM feature, in which one can send a maximum number of 6 to 10 messages per minute. On the other hand, if we use the GPRS feature and use it to send messages, then we can send around 30 messages in a single minute. So obviously, GPRS is much faster than the ordinary GSM networks alone.

There are certain protocols that GPRS is compatible with.

Firstly, there is the Internet Protocol or the IP. We use the Internet on our mobile phones very often and the in-built browser which the phones have, use the Ipv4. This is because the Ipv6 is not that widely used as of now.

Secondly, there is the Point-to-Point protocol or the PPP. This is mostly not compatible with the mobile phones but there are certain phones that can be used as a modem and used by the computer to connect to the Internet. Through this process the PPP can be used to channelize the Internet Protocol to the phone. Then there is an IP address which is automatically added to the cellphone which is being used as a modem.

Thirdly, there are the X.25 channels. This technology is used for payment consoles which are wireless. X.25 is compatible over PPP and IP. But to build this support, a network router is needed and this is used for the device which is being utilized by the user.

If ever, the TCP/IP is utilized, then a single phone using GPRS can have multiple IP addresses assigned to it. GPRS stores and then forwards the IP data packets to the cellphone when you are changing from one cellphone to another. The function of TCP is to see if there is any loss of packet data and then resolve the situation accordingly. A loss of data can lead to a temporary slowdown in the transmission speed.
