Interactive Satellite Remote Education System Based on Bluetooth and GPRS

Abstract

Because of the advantage of broadcast and the lower-cost satellite, tele-education is an important distance education method. However, the current satellite-based distance education systems use one-way reception mode, so it is unable to meet the needs of the user interactive learning, which limits the application of satellite-based distance education. Against the limitations of the existing satellite remote education system, this paper proposes a communication method based on Bluetooth and general patio radio service (GPRS). The end-user sends requests to the mobile phone via Bluetooth; mobile phones carrying the requests move to the place where there is mobile network coverage, then mobile phone sends the requests to the gateway by GPRS/GMS, and finally, the requests are forwarded by the gateway to the broadcast server. This approach is compatible with existing satellite-based distance education system. Since the scheme is based on the widely deployed wireless communication network, which made it easily to deploy and cost less..
