Students of the Institute of Informatics and Business (IBI) Darmajaya city, Novitalia, creating neutralizing mobile phone signal ("cellphone jammer") to be installed in the mosque or place of worship that can not be reached during the run praying.
"Cellphone Jammer serves to counteract signal HP for pilgrims to avoid interference calls and SMS to worship, pray so fervently without noise HP," said Novitalia, in city, on Wednesday (28/1).
According to him, the congregation often forget to turn off the phone when they want to pray, so often when prayer takes pilgrims receive a phone call or SMS is finally distract their worship and devotion.
"The cellphone jammer, pilgrims do not need to bother to turn off automatically for HP HP could not be reached, given the signal that there has been blocked by the tool," he said again.
He said the working principle of this device is the use of GSM transmitter component (jammer) which can counteract signal HP, so that when the device is installed in the mosque, then the hours of prayer will work to counteract signal that HP could not be contacted.
"This transmitter works on 88--108 MHz frequency range and has a radius of more than one kilometer, so that HP is the radius is automatically signal will be lost and the phone can not be contacted. When this is applied in place of worship would be able to help calm the worshipers worship, "he said.
Cellphone jammer, he said, consists of designing hardware and software (hardware-software). Hardware design consists of a "power supply" and "jammer" (transmitter). "To design a software tool includes flowchat of neutralizing system signals the phone," said the student of Computer Systems 7th semester it.
The other major component is the "real time clock" (RTC) which serves as a timer. RTC is a clock on the computer that serves as the custodian of the start of the second, minute, hour, day, date, month and year.
"RTC function for setting the time. Setting the time taken from the beginning of the prayer until the time of prayer. As the dawn prayer schedule or dawn, when the early morning prayer likened 04.12 pm and ends at 04:50 pm, it automatically means it works to counteract the signal between the span 04.12--04.50 pm, "he said.
