THIRD GENERATION WIRELESS TECHNOLOGIES : BOON TO M - LEARNING APPLICATIONS

In the recent past, wireless technologies are rapidly replacing the plain old "wired" technologies in all walks of life. Lot of research is going on, in the area of wireless technologies for transporting maximum amount of digital information in less time by using minimum amount of both power and spectrum. Bluetooth, Zigbee, G.S.M, C.D.M.A etc are some of the areas where the advancement is witnessed in multy-fold.
First-generation (1g) of wireless networks are mainly "Analog" in nature whose main purpose is to transport signals like "voice" etc. They were not capable of sending the digital information.
The second generation (2g) is a digital world, enabling us to transport not only "voice" but also "data", but with limited speeds. By using architectures like G.P.R.S. (general packet radio switching) , users can send and receive, the digital information upto 128 kbps (kilo bits per second). In the subsequent revision of the second generation wireless technologies (2.5 g), the speed of transmission of e-content has been increased to 384 kbps. By using another advanced architecture, namely, E.D.G.E (enhanced data rates of global evolution). In this way, tremendous improvement is achieved, through research, in the speed of trasportation of digital information of the forms like image, audio, video, text and multi-media.
The third generation (3g) of wireless technologies, totally revamped the situation with its emaging power of speed, to trasport the digital signals with high bit rates of the order of 2mbp/s (two mega bits per second). This particular attribute/quality of the 3g wireless system, enabled the users to make it as a natural choice for a variety of web-based applications to run. The combined strength of information technologies (like web 2.0), 3g wireless technologies, powerful protocols and innovative application programes, made it seemless for mobile teaching and learning.
In this presentation, an effort is made inrespect of harvesting the said tecnologies for the best utilisation of m-learning. A few examples are cited in the presentation, where the economic growth, medical information, community development, disauster management etc are drastically improved through m--teaching and learning concept of "any where, any time" of information flow.
