Managed access is managing cellular network access from contraband phones within a corrections facility.
Managed access differs from
cellular jamming technologies, which are outlawed in the United States. A managed access system functions like a
femtocell
In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. A broader term which is more widespread in the industry is ''small cell'', with ''femtocell'' as a subset. It c ...
or low-power
cell tower which passes calls to cellular carriers; however, only communications from approved devices and emergency calling are allowed.
The managed access signal appears as an extension of nearby commercial cellular signals; once a phone connects to the network its identifying information is compared with approved devices and communications are accepted or denied.
Managed access networks work with commercial cellular signals including
2G,
3G,
4G/LTE, and
WiMAX
Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options.
The WiMAX ...

In 2010, the
Mississippi Department of Corrections tested the first managed access system at
Parchman Mississippi State Penitentiary; during one month the system blocked more than 216,000 texts and 600 phone calls. In 2013, the
FCC recommended that prisons be allowed to manage their own network access without having to seek approval from the agency, saying that the process of inspecting the systems is "time-consuming and complex" and "discourages their use". In a 2016 op-ed, FCC Chairman
Ajit Pai requested that the reforms proposed in 2013 aimed at loosening regulations on managed access and other solutions used to prevent the use of contraband cell phones should be enacted.
As of 2016, only California, Maryland, Mississippi, South Carolina, and Texas had tested managed access systems.
Drawbacks
Managed access systems are unable to stop the use of contraband devices using Wi-Fi to connect to the internet. Deployment of managed access systems requires FCC approval
and may require consent from cellular network carriers. The devices can also cause interference outside of the prison if they are not properly implemented.
