Satellite e-Learning

The ability to transmit an actual classroom lesson to remote locations is what satellite e-learning is all about. The remote classroom can be either an individual's desktop computer or another (offsite) classroom full of students.

Satellite e-learning provides a synchronous learning environment. Sometimes referred to as BTV/IP (Business Television/Internet Protocol), satellite e-learning has brought distributed media into the 21st century.

Satellite e-learning utilizes internet protocol (IP) for networking and distribution. IP makes it possible to utilize high bandwidths for video streaming because it bypasses the wide area network.

Students located at remote locations are able to communicate with the instructor via audio teleconferencing or by using a combination of audio and keypad technology.

With satellite e-learning, students can participate in class along with the instructor and the other students. The only real difference is that some students are not sitting in the same location as the instructor. With satellite e-learning, instructors are able to incorporate all of the different media into their lessons.

Transmission to remote students is consistent and occurs faster than other methods of transmission. Satellite e-learning makes synchronous oral interaction possible which can greatly benefit students since they are able to ask questions and receive answers in moments.

Satellite e-learning utilizes internet protocol which bypasses wide area networks and the Internet. What this means in simple terms is that the problems often associated with bandwidth (distorted images, slow transmission) are eliminated.

Very large-sized web-based training modules and multi-media-rich transmissions can easily be transmitted using satellite technology. There is virtually no limit to the number of remote locations that can receive satellite transmission, provided the remote locations maintain the necessary equipment.

The technology and infrastructure needed to support e-learning is extremely expensive. The infrastructure also requires a high degree of maintenance which adds to the overall costs. Logistically, satellite e-learning can be difficult to set up. A designated classroom outfitted with the equipment needed to broadcast classroom instruction must be identified.

In addition to the equipment, an individual trained in the area of broadcasting must always be present to operate the equipment and prepare the broadcast. Instructors also need training in this method of instruction.

Satellite downlinks, which are the locations that receive the satellite broadcast, also must be outfitted with the equipment necessary to receive the broadcast. Because the transmission will travel across the local area network before it can be received by the remote location, it is at this point that recipients sometimes experience problems.

Another limitation of satellite e-learning is that it doesn't allow for flexibility in scheduling. Students do not have the option of learning at a time that is convenient. They must participate in the satellite broadcast as it actually is taking place.

This type of instructional media is perfect for role playing, guided and/or panel discussions, simulations, demonstrations, case studies, traditional lecture-style narration, brainstorming, practicing and drilling.
