Wearable, connectable, accessible, flexible, and economical: Wireless handheld devices are the potential technologies for ubiquitous computing to happen today computing that unobtrusively threads itself through the fabric of everyday life [1]. This latest trend called calm technology is being absorbed into electronic learning where in a higher level of learning mode called quiet and pervasive learning is emerging out. Ubiquitous learning (ulearning) is a trend that has emerged due to matured mobile technologies, paving the way for any time, any where learning and also providing the learning services based on learner’s preferences, location and context. Present learning systems generate large amount of data that cannot cope up with the data challenges arise in such ubiquitous computing systems. So Grid, a technology introduced to handle geographically distributed learning content, is used to harness and maximize the utilization of Grid fabric (bandwidth). In this paper, Grid is considered as a platform to provide content repository that improves the content delivery mechanism as well as distributed storage capabilities. Wireless technologies like Radio Frequency Identification (RFID), Bluetooth and Wireless Local Area Network (WLAN) are used to offer location and context aware services, whereas web technologies like web services, Composite Capabilities/Preferences Profile (CC/PP) are used to render the learning content according to device capabilities. This paper outlines the usage of mobile, wireless, web and Grid technologies for ulearning.
