    A Case Study of Mississippi State Penitentiary’s Managed Access Technology
    (2015-08) Grommon, Eric; Carter, Jeremy G.; Frantz, Fred; Harris, Phil
    Managed access technology allows the completion of authorized calls placed from approved phone numbers (numbers that have been vetted and entered into a database) while blocking calls to or from devices or numbers that have not been pre-approved. This process is often referred to as “white-listing.“ The overall conclusion of this study is that managed access technology does capture a large quantity of cellular transmissions, but it is impossible to determine the rate with which attempted calls or texts successfully elude detection by the system. Even if a hypothetical rate of successful transmission detection was only 40 percent, however, that 40 percent would provide a substantial value-added effect to combating contraband cell phones. Thus, the decision about whether or not to use managed access technology is whether its possibly limited impact (blocking less than 100 percent of contraband calls) is sufficient to warrant the cost of installing and maintaining the managed access system. A series of interviews and teleconferences, in addition to the secondary analysis of managed-access system data, were used to produce a fundamental understanding of managed access technology operations, identify challenges and lessons learned, and develop a baseline of contraband cell phone activity. This report acknowledges that the study did not attempt to quantify potential vulnerabilities or manipulations of managed access systems. Although such an evaluation would be beneficial, it was beyond the scope of this study. 18 figures, 13 tables, 40 references, and appended examples of contraband cell phone activity, MSP managed access system infrastructure, and evaluation protocols

    Impact of Mobile Broadband Data Access on Police Operations: An Exploratory Case Study of One Medium-Sized Municipal Police Department
    (2014-02) Carter, Jeremy G.; Grommon, Eric; Frantz, Fred
    As used in this study, “mobility” refers to “an inherent ability to move about,“ and “mobile computing” is a generic term that refers to the functional capabilities possible for end users as they complete tasks from various physical locations. “Broadband” refers to the relatively wide bandwidth characteristics of the wireless transmission medium and its corresponding ability to support multiple users and/or transport suitable quantities of data. “Mobile broadband” is used as a generic term to collectively refer to both terms in the context of the aggregate capabilities made possible through their use compared to other available mobile solutions and/or data. This study notes the lack of public-safety access to wireless broadband data, given resource limitations and a lack of independent evidence that would justify procurement of such technologies for police work. The current study’s deployment and assessment of this technology involved its use by the Brookline Police Department (BPD). Overall, the semi-structured interviews suggest that the wireless broadband technology was implemented with minimal difficulties and produced a number of perceived benefits for the BPD. The most direct benefit was the ease with which departmental technologies could be managed. Additional benefits were associated with increased access to timely information, increased information flow, and increased quality of reports. Structured interviews indicated that a few weeks of training sessions and ongoing informal bulletin and email disseminations were needed to overcome skepticism about the transition to wireless broadband. Most of the uniform personnel did not oppose the implementation nor did they perceive that the department was opposed to the transition. 39 tables, 3 figures, 93 references, and appended methodological details and supplementary data.
