Ericsson holds about 28 MA-L blocks registered as "Ericsson AB" at Torshamnsgatan 36, Stockholm, Sweden, plus regional registrant strings such as "Ericsson, EAB/RWI/K" (e.g., 90:55:AE, Gävle). Verified samples include 98:A4:04, 54:9B:72, 1C:90:BE, 74:C9:9A, and 90:55:AE. These OUIs appear on carrier/telecom infrastructure (5G/LTE base stations, radio, core networking, microwave/transport) and, via its Cradlepoint subsidiary, on enterprise cellular WAN gear. Ericsson completed its acquisition of US-based Cradlepoint on 2 November 2020 for an enterprise value of about USD 1.1 billion, and Cradlepoint retains its own OUIs (cross-reference the Cradlepoint entry from Batch 007). The legal parent is Telefonaktiebolaget LM Ericsson, while the operating entity for OUIs is Ericsson AB (with some blocks under regional unit codes). For triage, an Ericsson AB OUI is a carrier-infrastructure signal (RAN/transport/core) and is rare in enterprise LANs except in operator or lab environments, while Ericsson's cellular-WAN gear appears under the Cradlepoint OUIs instead.
