Is it possible to set RFID tags to a frequency that is identical to mobile or Wi-Fi signals?
No, you cannot change a tag's frequency, as that is established by the manufacturer. Some tags do work with Wi-Fi access points, though. There are also tags that can connect to cell networks to transmit information at locations where there are no RFID readers. Keep in mind that using the same frequency as another device could lead to potential interference problems.
