Sierra Wireless holds 6 MA-L blocks (about 100.7 million addresses) registered as "Sierra Wireless, ULC" (also "Sierra Wireless") at 13811 Wireless Way, Richmond, BC, Canada. A verified sample is 28:A3:31. These OUIs appear on cellular (2G–5G) modules and embedded modems, as well as Sierra-branded AirLink gateways and routers. Sierra Wireless was acquired by Semtech, completed 2023-01-12 in an all-cash transaction with a total enterprise value of about US$1.2 billion (US$31.00 per common share). The entry has two analyst angles: for embedded modules, this is an "OUI ≠ host brand" case (the OUI identifies the Sierra modem inside a third-party device), while for AirLink gateways and routers the OUI maps to the Sierra brand. Some Sierra modules generate randomized or per-boot MACs per vendor forums. For triage, a Sierra Wireless OUI is either an embedded cellular modem (classify by the host device) or a Sierra AirLink gateway (a fixed networking asset) — distinguish by device context.

- TWO angles — (a) embedded modules: "OUI ≠ host brand" (the OUI identifies the Sierra modem inside a third-party device); (b) AirLink gateways/routers: OUI = Sierra brand. Some Sierra modules generate randomized/per-boot MACs. Acquired by Semtech (2023-01-12). The IEEE registry publishes no assignment dates, so none is stated here. [Confirmed]
