CORAL SPRINGS, Fla.–(BUSINESS WIRE)–The battle to remove cell phones from the hands of prison inmates saw a major breakthrough this week. The National Telecommunications and Information Administration (NTIA) authorized the first federally sanctioned test of cell phone signal jamming technology inside the Federal Correctional Institution in Cumberland, MD using CellAntenna technology.

“This test should be a wakeup call for legislators and corrections departments everywhere, because it proves that cell phone jamming is a solution for making our prisons safer.”

CellAntenna, experts in jamming and boosting cell phone signals, demonstrated how jamming can be surgical enough to block illegal signals without affecting cell phone communications outside the prison perimeter. The February 17 test drew support from Maryland Governor Martin O’Malley, who backs allowing states to use jamming technology to curb problems resulting from prison inmates using contraband cell phones from inside correctional facilities.

The demonstration of this technology supports S251, a bill that is currently awaiting House approval, which would allow state authorities to use cell phone signals jamming devices in prisons. Under current law, only Federal agencies can use the technology.

“The issue of contraband cell phones inside America’s prisons has reached pandemic proportions, and this test is a big step toward ending the deaths and illegal activities that can be linked back to convicts with cell phone reception. The Federal government and the NTIA are acknowledging the fact that cell phones in prisons pose a deadly and unnecessary risk to citizens,” said Howard Melamed, CellAntenna CEO. “This test should be a wakeup call for legislators and corrections departments everywhere, because it proves that cell phone jamming is a solution for making our prisons safer.”

CellAntenna is cooperating with the NTIA and other Federal agencies to develop standards for jamming in prisons because the agencies recognize that the best solution to the issue of contraband cell phones is jamming.

The Maryland test comes after another conducted at a 400-inmate correctional facility in another state where CellAntenna’s new CJAM-CPC cell phone controlling technology was able to identify 239 cell phones.

“Quite obviously, the problem of cell phone use in prisons is bigger than anyone had thought,” said Melamed. “More than half of the inmates in the prison had cell phones, which is greater than the 10 percent rate that was expected.”


  1. With all due respect , using jamming systems in prisons is a waste of taxpayer money as the jamming systems can easily be circumvented with Skype Internet and Satellite phones. Jamming cannot be done on frequencies as strong as these without serious health risks. Ireland found out the hard way. See article link:

    Many of the prisoners are not only NOT STUPID, they are resourceful. They will obtain the skype and satellite phones. According to the latest reports, cell phones are commanding up to $2000 per phone. At that price, they will make it in no matter how thorough the searches are (if not visitors or vendors, then the guard themselves). The terrorist prisoners are truly a threat to national security with these phones.

    The only answer to address this problem is to standardize universal protocols. Doing such will also permit parents, teachers, judges, pastors, public transportation officials, hospital administrators, and business owners have an optional tool to easily eliminate their respective cell phone problems.

  2. If i was in prison i would want my cellphone smuggled in for me so i could just play solitare and teeter all day. Oh, and check mobilitydigest to read the latest posts. cant mess up my daily scheduled readin haha

  3. Cell phone jammer is an interesting and helpful device when we don’t want to be bothered by the cell phone noise. I just bought myself a cell phone jammer the other day from ,it is working great and BTW, it’s legal here in my country.
