Curvalux holds a single MA-L block, 40:9C:A6, registered to "Curvalux" at Electric Works, 3 Concourse Way, Sheffield S1 2BJ, United Kingdom — the IEEE registrant address, which sits with the company's R&D and European operations rather than its corporate front office. Curvalux is a fixed-wireless-access (FWA) vendor built to attack the digital-divide market: its hardware is outdoor, carrier-grade gear for WISPs and telecoms operators, not consumer or enterprise LAN equipment. The lineup centers on phased-array "Edge Node" base stations and matching CPE running point-to-multipoint links across unlicensed sub-6 GHz (2.4/5/6 GHz) and millimeter-wave (24–31 GHz) spectrum, with solar-capable designs aimed at rural and underserved deployments. The corporate structure spans both sides of the Atlantic: the UK operating entity (Curvalux UK Ltd) is part of US parent Airspace Internet Exchange Inc, headquartered in New York. In October 2022 Curvalux merged with Cambridge Broadband Networks Group (CBNG), bringing the VectaStar licensed-band mmWave PtMP platform in as a subsidiary, and in August 2024 it took strategic investment from Pegasus Capital Advisors' Subnational Climate Fund. Because IEEE publishes no OUI registration dates, any "date registered" (third-party tools show 2021-06-08) is a database artifact, not an IEEE fact, and no allocation date is recorded here. Practically, a 40:9C:A6 sighting is a strong signal of Curvalux FWA infrastructure — an outdoor base station or CPE in a WISP or carrier fixed-wireless network — rather than anything on a typical office LAN.

- Security context
- no CVEs or public vulnerability disclosures found for Curvalux devices as of June 2026; gear is outdoor carrier-grade FWA infrastructure (no consumer/IoT profile) [Likely — absence of finding, not proof of none] — no source
- Analyst note
- a 40:9C:A6 OUI sighting indicates Curvalux FWA infrastructure (outdoor Edge Node base station or CPE) in a WISP/carrier fixed-wireless network, likely a rural or underserved-market deployment; not a consumer or enterprise LAN device. Active deployments include the Philippines and the UK [Confirmed] — wifinowglobal.com (https://syndicated.wifinowglobal.com/resource/curvalux-secures-multi-million-dollar-order-from-philippines-telecoms-giant-following-successful-trial/)
