If deemed legal, an Iowa school system may purchase cell phone jamming equipment. Earlier this month, the school system passed a motion to allocate 5000 dollars to purchase technology to block cell phone signals at school.

The school would require that the cell phone jamming equipment would need to be capable of turning off easily and instantly should there be an emergency.

In 2005, a Federal Communications Commission law banned sale and use of transmitters that block cellular or personal communications signals.
