hi everybody.
i have a question. there are some kinds of devices don't let the cell phones work properly. they are used because of security problems at meetings, weddings, exhibitions etc...
i wanna learn about them. but, because of i dont know their names, i cant have googling. so do you know about it. At least a name for searching in the web?
thanks for reading.
bye.
