Midmark RTLS — 2 prefixes (MA-L)

A MAC address starting with 00:45:01 or 78:C9:5E belongs to Midmark RTLS, a healthcare real-time locating system (RTLS) brand operated by Midmark Corporation, typically seen on hospital infrared (IR), Bluetooth Low Energy (BLE), or Wi-Fi locating tags, sensors, and beacons deployed in clinical settings.

Midmark RTLS holds two confirmed IEEE MA-L (24-bit OUI) assignments — 00:45:01 and 78:C9:5E — both registered to a Traverse City, Michigan address tied to Midmark's facilities. Two independent registrations under the same organization name set this apart from a bare single-OUI registration with no further substance.

The company behind the OUIs is substantive: Midmark RTLS operates a dedicated healthcare product line, "CareFlow RTLS," sold by Midmark Corporation, a long-established U.S. medical, dental, and veterinary equipment manufacturer. Midmark markets CareFlow RTLS for tracking staff, patients, and assets in hospitals using a hybrid of infrared, BLE, and Wi-Fi locating technology, and a related "MIDMARK RTLS SOLUTIONS, INC." trademark registration was located during research.

No CVE for Midmark RTLS is recorded in the NVD as of an August 2026 search, and no malware or trojan association was found for either prefix in any source checked. A same-named but unrelated Siemens product, "SIMATIC RTLS Locating Manager" (CVE-2025-40751), surfaced in searches but belongs to a different vendor entirely and must not be attributed to Midmark.

Neither 00:45:01 nor 78:C9:5E is a slice of a shared IEEE Registration Authority base like 70:B3:D5 or 8C:1F:64 — both are dedicated MA-L blocks attributed solely to Midmark RTLS in the registry, so no shared-base caveat applies to this entry.

Registration dates

Unknown — IEEE's MA-L registry publishes no assignment/registration date column; third-party "date registered" values (e.g. maclookup.app) are database artifacts, not IEEE facts [Confirmed]

Related entity

Special note

Neither prefix is a slice of a shared IEEE Registration Authority base (e.g. 70:B3:D5, 8C:1F:64); both 00:45:01 and 78:C9:5E are dedicated MA-L blocks attributed solely to Midmark RTLS [Confirmed] — the IEEE MA-L registry

Analyst note

Two confirmed OUI assignments plus a real, findable clinical RTLS product line (CareFlow RTLS) distinguish this entry from a bare single-OUI shell registration [Confirmed] — https://www.midmark.com/medical/rtls
