The School of Industrial Polytechnic University of Cartagena (UPCT) can offer from now students the opportunity to listen to the lessons the teacher from mobile, through a system of wireless transmission of audio streaming which has professor developed Information Technology and Communications Francesc Burrull.
"The 'wifiClashroom' is designed to solve problems of reverberation in classrooms and provide students with the best sound of the teacher's explanations, especially important in the subjects in a foreign language," says Antonio Guillamón, director of Industrial.
"The transmission of the microphone bearing the teacher and is broadcast 'multicast' format through a router that creates its own wireless network to which students with their phones connect and from receiving the audio signal" Burrull details.
The researcher has developed the system with both a fixed router, wired as a portable, powered with a battery that allows six hours of uninterrupted broadcast.
Allowing you to use the device outside the classroom and use it in other areas.
"It would be perfect for tourist groups, which usually no way to hear the guide well," exemplifies Burrull.
The system allows wireless saturation of multiple mobile devices and can receive audio signal with vivid clarity from tens of meters.
By using its own network wifi, the delay is at least about 20 milliseconds, and still expects to reduce Burrull using microphones that automatically digitize the analog signal.
"It would still be lower frequencies broadcast by radio, but there could be interference problems," he says.
The idea of ​​the universal use of smartphones, which already took a few years to Burrull develop the device 'wifitickets', with which catering establishments can provide its key customers access to their personal WiFi network and time limited.
