Bay State College creates a safe campus through digitized contact tracing
Contact Tracing
Founded in 1946, Bay State College in Boston, provides students with relevant hands-on skills and a strong educational founda- tion. The college is known for its small classes, personalized attention and career-focused curriculum. Bay State’s education helps students achieve their full potential as ethically and socially aware citizens.
Resume On-campus Classes
During the early days of the COVID-19 pandemic, leadership at the private college began exploring how they could safely resume on- campus classes in the fall of 2020 and maintain operations should isolated parts of the community contract COVID-19. The Informa- tion Technology team at Bay State College came up with a unique and novel solution to the problem that focused on contact tracing as a key pillar of a layered safety solution.
The college wanted to align its re-opening plan with government health department guidance stating contact tracing as one of the most important efforts to help slow the spread of COVID-19. But administrators knew that manual efforts to identify who on campus has been in contact with whom would be time-consuming and likely insufficient to catch and stop transmission. It was equally important for a contact tracing solution to strike a balance between individual health safety and personal privacy.
HID Global’s BEEKsTM Bluetooth Low-Energy (BLE) beacons are at the core of a robust contact tracing solution at Bay State College. They help ensure that only trusted students, faculty, staff members and visi- tors can enter the campus, and that the campus itself can be trusted.
The college found the HID beacons in the form of badges to have the benefit of being an easy extension of existing ID cards. As an alternative to badges, users can carry HID fobs with these same bea- con capabilities. The HID fobs or badges can be issued to anyone entering the premises, and administrators can define all distancing policies and alert parameters for mitigating an infection outbreak per public health guidelines.
Here is how it Works
• Installation. The college installed a new wireless network that includes access points with dedicated Bluetooth radios and anten- nas throughout its campuses.
• Detection. The Wi-Fi network is used to detect HID BEEKs BLE beacons.
• Badging. Each student, staff, faculty member and visitor on campus must carry a beacon inside a badge holder on a lanyard at all times. Since they are carried around campus, the beacons generate roughly 300,000 lines of location data per day. This information is captured and stored in a database for real-time and historical analysis. By querying this database, the college can triangulate the location information from multiple access points to determine the relative location of everyone on
campus—much like how GPS is used with cars and phones.
In the unfortunate event that a person becomes infected, univer- sity administrators can quickly learn where the person travelled on
campus, identify those who were in contact with the person for at least 10 minutes, and notify those people, so they can be isolated and monitored.
Balancing individual health safety and personal privacy, all data col- lected using the beacon is destroyed after the 14-days, in accordance with the typical viral infection period. During those 14 days, the data can only be accessed by senior IT department staff, and used only for contact tracing purposes. Also, the beacons only transmit a device Media Access Control (MAC) address that does not contain any personal information, making it useless to anyone outside the IT department.
The college also uses the HID beacon data to monitor a real-time count of the number of people on campus at any point in time. This ensures that they are following Massachusetts state and local occu- pancy level guidelines.
Resume Classes Safely
“HID BEEKs beacons are integral to a contact-tracing solution that has enabled us to safely resume in-person classes,” said Jeffrey E. Myers, chief information officer at Bay State College. “This solution will also help us keep our campus operational should isolated parts of our community find themselves infected.”
HID Global has played an integral role in the college’s mission to deploy a solution that protects students, faculty, staff members and visitors. Looking beyond contract tracing, the fobs and badges can be used for creating zones with geo-fences around high-traffic areas to minimize large congregations of people in the future.
