CDCR Halts Roll Out Of Managed Access Cell Phone Jamming

CDCR halts managed access deployment in state prisonsThis news tracks with reports elsewhere that this technology to block cell phone usage in prisons is problematic. An effective contraband cell phone strategy should focus on reducing demand, in addition to restricting supply.

Corrections officials have shared with us the fact that at least 40% of the calls intercepted by these systems are to phone numbers on inmates’ approved calling lists. We suspect that an even higher percentage are to other family and loved ones not on the limited list of allowed contacts and are also non-criminal wireless usage.

The California Department of Corrections and Rehabilitation (CDCR) cannot say it was not warned that the high-tech system it was deploying to stop rampant, forbidden cellphone use by inmates in the state’s 34 prisons probably would not work.

The 2012 report by the California Council on Science and Technology said the system wouldn’t block 4G, Wi-Fi, MiFi, Skype, text messages or satellite transmissions. It can’t triangulate radio signals, limiting its effectiveness in identifying specific phones or users. And radio frequency leakage could interfere with regular cellphone usage, affecting the public’s access to 911 operators.

But the state forged ahead, installing the system at 18 prisons before deciding it wasn’t working.

The Associated Press reported on Wednesday that the department has halted expansion while options are pondered. “It’s been difficult to make sure the technology can handle those upgrades,” CDCR spokeswoman Dana Simas told AP. “Whether we’re going to scrap it or whether we can find solutions to these issues, that will be determined later.” “What remains to be determined is if the constant upgrades performed by the vendor will be sustainable in the future,” Simas said.

The report had called the state’s long-term investment in untested technology “unwise” and premature, especially in light of the fact that it really doesn’t even know how many illegal cellphones are floating around the prison system. The council recommended using airport-style screening systems for all personnel and having private carriers identify and disable illicitly obtained phones.

“In point of fact, there are no prisons anywhere in the United States using a functional managed access system to control cell phone use,” the report said.

Prison officials go to great lengths to prevent cellphones, often stolen, from being slipped into the prison by employees or visitors. It doesn’t work very well. Charles Manson, a high-profile 81-year-old killer, was recently caught twice with cellphones used to call around the country. A visitor was caught with a third phone meant for him, in a hallowed out boot heel.

Global Tel-Link’s blocking system made it into 18 of the state’s 34 prisons, and for now that seems as far as it’ll go, because cell phone companies of 2015 are using drastically different networks than the companies of 2011. Between 4G and Long Term Evolution services, phone companies are transmitting calls over a system that has more in common with a wifi network than old-school cell connections.

AP said the number of cellphones grabbed in California prisons declined markedly from 15,000 in 2011 to 8,000 in 2015. But the inmate who talked on his illicit phone to Vice reporter Seth Ferranti in February described a very active tech scene.

“All my homies that got phones, all of us are friends on Facebook. Niggas be making rap videos, they be filming riots and filming shit that’s going on and putting them on YouTube.”

The inmate, a lifer called “Big Smoke,” said, “The cellphones is rampant up and down the coast of California.” He claimed most of the phones were brought in by staff, but, “Some inmates is even smuggling them in now because it’s so profitable. They smuggling in memory cards, chargers, cords, anything that has to do with a cellphone. All that stuff goes for $50 a pop. Every part that has to do with a cellphone is profitable. The black market is big.”
