BI Incorporated announces BI TAD® cellular capability

Transdermal alcohol monitoring data can be transmitted via wireless

Boulder, CO

BI Incorporated announces BI TAD, an ankle-worn device that continuously monitors alcohol consumption of community-based offenders, now has cellular capabilities. This is a first for community corrections in that continuous alcohol monitoring data can now be transmitted via wireless communications.

TAD continuously monitors alcohol consumption through a noninvasive skin sensor installed on the offender. The TAD system also includes electronic monitoring so agencies can monitor offender curfews and schedules. The wireless capability is now available with the addition of a new base station, called HomeBase Cellular, that can be installed in offender’s home if the individual does not have a landline.

“So many households do not have landlines today. By offering TAD with wireless capabilities, federal, state and local corrections officials can obtain continuous alcohol monitoring, even when the offender does not have a landline phone,” said Jock Waldo, vice president of marketing, BI Incorporated. “This is a major step forward for community corrections.”

More than one-in-four U.S. homes, or 26.6 percent, had only a wireless phone as of June 2010, up from 13.6 percent in 2007, according to a recent U.S. Department of Health and Human Services study. The new HomeBase Cellular was approved by the Federal Communications Commission and certified by major wireless phone carriers, including Sprint and Verizon.

TAD consists of an ankle-worn bracelet, which includes a sensor that detects drinking events; a base station placed in the offender’s home; and a host computer maintained at BI’s national monitoring center. The TAD sensor measures for drinking via sweat or vapor, logs that data in the home base station, which then wirelessly forwards that data to the host server. That data is then matched against an offender’s profile, and supervising authorities are alerted if abnormalities exist.

Other TAD features include:

  • Waterproof (up to three feet)
  • Durable design that holds up in challenging environments
  • Receiver that operates via landline or cellular connection
  • Alerts in multiple forms (fax, email, PDA) are sent to supervising officers
  • Six-month field-replaceable battery
  • Lightweight device weighs eight ounces
  • Extensive tamper-resistant features to ensure system reliability
  • 24/7 technical support from monitoring center and product specialists
  • Secure officer login available at
  • Variable range settings for curfew monitoring
  • Compatibility with other BI products, including GPS tracking
