Abstract. The recent growth of ubiquitous computing brings to the network industry the new classes of home, campus, and mobile networks. This would enable learning institutes to provide services to learners anywhere, anytime and not only through fix devices, but also through ubiquitous end user devices. Realising these capabilities would require an architecture which supports context awareness functionality and an understanding of the environment by the system. In this paper we present an architecture which supports ubiquitous live streaming for university or campus networks using a modified Bluetooth inquiry mechanism with extended ID, integrated end-user device usage and adaptation to heterogeneous networks.   Riding on that architecture, services that can be provided by the learning institute include but not limited to live video streaming, e-document delivery and virtual notice boards. For the ubiquitous live streaming, mobile end user devices play the master or coordination role to identify which end-user device from a pool of devices the streaming should be sent to. The remaining components work together to ensure context awareness, flexibility and much more reliability of the system.
