Update
There was a mistake in this SBAR regarding connecting devices to UMHBYOD. New registrations are no longer accepted for that network and users should use MU Health Care network with their MU credentials. The updated SBAR is as follows:
S Situation
There will be maintenance performed on the MUHC Cellular DAS (Distributed Antenna System) Wednesday, 03/25/26 from 1200 – 1230 for maintenance and hardware optimization.
B Background
Investigation and troubleshooting on the Cellular DAS has uncovered an issue with the AT&T configuration on the hospital system. Connectivity Wireless will perform maintenance on the Cellular DAS to make corrections to the AT&T signal set.
A Assessment
On Wednesday, 03/25/26, from 1200 – 1230 we will experience a Cellular DAS outage on all cellular carriers throughout all MUHC DAS covered buildings while engineers work on updating AT&T’s configuration.
R Recommendation
All MUHC staff members and departments should be aware of a planned DAS Cellular Outage for Wednesday, March 25, 2026. from 1200 – 1230. The Telecom Department will be paging overhead during this change window due to an outage of all cellular coverage throughout MUHC. Please ensure all MUHC and BYOD devices are connected to the MU Health Care wireless network. Managed iPhones and iPads will be connected to UMHWirelessII.
