Enhanced protocols for pedagogical through mobile learning

This paper is intended for on how mobile technologies can play an important role in the evolution of M-learning. In Second Generation, GSM can be introduced in three ways such as general packet radio services, continuous connection to the internet not requiring dial-up connection reaching up to 171.2 Kbits /s. Secondly, Blue tooth is a chip technology, that allows short range data and voice transfer among mobile devices. Thirdly, multimedia messaging service, which incorporates graphics and images into text messages. 2G services are frequently referred as personal communications service (PCS) and SMS messaging is available for data transmission. In third generation, EDGE can be introduced in two ways: as a packet-switched enhancement for general packet radio service (GPRS), known as enhanced GPRS or EGPRS, and as a circuit-switched data enhancement called enhanced circuit-switched data (ECSD). The services associated with 3G provide the ability to transfer both voice data (such as making a telephone call) and non-voice data such as downloading information, exchanging e-mail, and instant messaging. 4G will be the successor to 3G. It will feature high-speed mobile wireless access with a very high data transmission speed. It also addresses the notion of pervasive networks, an entirely hypothetical concept in which the user can be simultaneously connected to several wireless access technologies and can seamlessly move between them.
