The technology of internet and wireless networks conceived the revolutionary concept of mobile learning or m-learning. Mobile learning through wireless enabled laptops within a university campus can make use of the learning management system that is already available through internet or intranet. Without restrictions within the four walls of computer labs or library, students can now access the learning resources anywhere in the campus where wireless access points or hotspots are located. We briefly investigate on the mobile learning concepts and also expand briefly on different wireless technologies, eventually emphasizing on a secure 802.11 network. Later an analysis of the student perceptions on mobile learning is presented through a survey and the future trends were discussed in conclusion.
