The Age Of Bluetooth and GPRS

gprs.jpgThe word ‘connectivity’ has evolved greatly from the times when it was first coined, to the present day, where we can call ourselves “globally connected.” Connectivity has disrupted barriers and can now link any set of people, irrespective of the distance separating them. This has largely been possible due to wireless communication, by the means of transmitted/received signals propagating through various frequency bands. The Internet has created a new universal space for information exchange, collaboration and commerce. As the human mind grows, so does the technology and the expectations of the masses aiming for greater customization and perfection of the services available to them.

GPRS, General Packet Radio Service is a communication service provided by many wireless telecom service providers, which offer easy dealing with data in the form of coded packets exchanged between the sender and the receiver. It has revolutionized the way people connect and has added an essential element of mobility, thus taking it to the next level. This service is designed for GSM networks, which is a digital cellular technology supporting mobile communication. In the age of Internet, where e-mails, e-conferences, e-commerce have added comfort and simplicity to our daily activities, the GPRS services have made easy inroads in the lives of businessman, professionals and even the students/tourists accessing web in remote locations through their handset.

GPRS introduces two major networks, namely Service GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN) for its smooth functioning. The SGSN technology manages the movement of data between mobile stations in the form of serialized packets and at the same time maintains the information about the location of the mobile station. GGSN, on the other hand, is a wireless gateway that allows mobile cell users to access private IP networks. The main benefits of GPRS are that it reserves radio resources only when there is data to send, and it reduces the reliance on traditional circuit-switched network elements, thus enabling voice calls and data traffic to be transported over a shared set of channels over the air.

Bluetooth, at the same time, is a short-range wireless radio service active between two Bluetooth-enabled devices, be it cell-phones, laptops, personal computers, printers, digital cameras, or any other. Bluetooth technology was first developed by Ericsson and then formalized by a group of electronics manufacturers including Ericsson, IBM, Intel, Nokia, and Toshiba. Other applications include wireless control of and communication between a mobile phone and a hands-free headset, dial-up internet access on personal computer or PDA using a data-capable mobile phone as a modem and many more. Such combination of using GPRS enabled handset connected to laptop/PC through Bluetooth can be effectively used to browse the web without being entangled with an array of wires. Bluetooth, which is an emerging technology is often thought of as wireless USB capable of pairing the devices through low consumption of power.

In this fast changing stage, where information floats everywhere, following you wherever you go, it’s just the question of how equipped you are to make the best use of it.
