AmpliTech Group, a U.S. manufacturer of 5G Open RAN radios, completed the first phase of the O‑RAN Global PlugFest Fall 2025 with its 64T64R CAT‑B Massive MIMO O‑RU. The test, held in coordinated laboratories in London (Digital Catapult SONIC Labs) and Berlin (i14y Lab), confirmed full multi‑vendor interoperability with G‑REIGN’s HTC‑based DU/CU stack and demonstrated stable beam detection across the 64‑antenna, 64‑stream configuration.
The 64T64R configuration is the highest‑capacity radio network design in the 5G ecosystem, enabling dense urban deployments that can support thousands of simultaneous users. By achieving interoperability in a demanding multi‑vendor environment, AmpliTech has positioned itself as a key U.S. alternative to the traditional closed‑vendor Massive MIMO solutions that dominate the market.
Management highlighted the strategic significance of the milestone. CEO and CTO Fawad Maqbool said, "Completing this initial phase of PlugFest is a major milestone for AmpliTech and for the Open RAN movement," underscoring the company’s focus on delivering U.S.‑made, secure infrastructure to Tier‑1 operators and private networks.
The next phase of PlugFest, scheduled for Spring 2026, will test end‑to‑end MIMO and gNB functionality, paving the way for commercial deployments. AmpliTech’s recent Q3 2025 earnings—$6.09 million in revenue and a narrowed net loss—were followed by a raised 2025 revenue guidance to at least $25 million and a 2026 guidance of $50 million, with profitability expected in 2026. The validation is expected to accelerate the company’s path to those targets by expanding its product portfolio and strengthening its competitive position.
AmpliTech’s validation also signals a broader shift in the Open RAN ecosystem. By proving that a U.S.‑made 64T64R radio can interoperate with leading DU/CU stacks, the company reduces operator dependency on a small group of closed vendors and offers a cost‑competitive, high‑performance alternative for dense urban, stadium, and industrial deployments.
