Key Terms

massive mimo, o-ran, fronthaul, open ran, +4 more

8 terms

massive mimo technical

"first open-source prototype of a massive MIMO (mMIMO) O-RAN system"

Massive MIMO is a wireless technology that uses large numbers of antennas at a cell site to send and receive many signals at once, boosting capacity and reliability like turning a single-lane road into a multi-lane highway for data. It matters to investors because it can dramatically increase network speed and efficiency, reduce per-user costs, and drive demand for equipment and services from telecom operators and suppliers.

o-ran technical

"a massive MIMO (mMIMO) O-RAN system achieving O-RAN Category B operation"

O-RAN, short for Open Radio Access Network, is a way of building the wireless network pieces that connect phones and devices to the internet using open, standardized software and plug-and-play hardware instead of closed, single-vendor equipment. For investors it matters because open systems can lower costs, speed innovation, and increase supplier choice—while also creating new competitive and regulatory risks tied to interoperability, security, and supply chains.

fronthaul technical

"Category B is the technically demanding fronthaul interface that enables this"

Fronthaul is the network connection that carries processed radio signals between a mobile network’s central processing equipment and its radio antennas at cell sites. Investors should care because fronthaul performance and capacity determine how fast, reliable, and upgradeable wireless services (like 5G) can be; improving or replacing fronthaul often means sizable spending, new business for equipment vendors, and impacts on a carrier’s ability to offer higher-speed services.

open ran technical

"The results align with growing momentum around Open RAN and next-generation"

Open RAN is an approach to building the radio part of mobile networks that breaks the system into standard, swappable pieces so equipment from different suppliers can fit together, like using Lego bricks instead of one molded toy. For investors, it can mean lower equipment costs, more supplier competition and faster innovation — but also potential integration and security risks that can affect telecom vendors, operators and capital spending plans.

beamforming technical

"showcased hybrid beamforming capabilities with a 2-layer MIMO configuration"

Beamforming is a technology that steers wireless signals in a focused direction so devices receive stronger, clearer connections instead of spreading radio waves everywhere. Think of it like aiming a flashlight beam at a specific person rather than lighting an entire room: it boosts speed, range, and reliability while reducing interference. For investors, beamforming matters because it can improve product performance, enable new services, lower network costs, and create competitive advantages for companies selling chips, equipment, or connectivity services.

mimo technical

"2-layer MIMO configuration, demonstrating sustained throughput under mobility"

MIMO stands for multiple-input multiple-output, a wireless technology that uses multiple transmitters and receivers to send and receive data at the same time. Think of it like several lanes on a highway letting more cars travel simultaneously and avoiding traffic jams. For investors, MIMO matters because it improves network speed and reliability, which can drive demand for telecom equipment, services and devices and influence revenue growth in wireless-related companies.

ran control plane technical

"from the physical layer up through the RAN control plane, can be assembled"

The RAN control plane is the part of a mobile network that handles signaling and decision-making for wireless connections — things like setting up calls or data sessions, handing a phone from one cell tower to another, and managing radio resources. For investors, it matters because who controls or modernizes the control plane affects network performance, cost and competitive dynamics; improvements or shifts (for example to cloud-based or open architectures) can change vendors’ revenue and operators’ operating expenses. The role is similar to an air-traffic control tower that directs flights while the planes themselves carry passengers.

openairinterface technical

"with the OpenAirInterface (OAI) CU/DU stack, marking the first time"

OpenAirInterface is an open-source software toolkit that implements the core and radio parts of mobile networks (such as 4G and 5G), letting engineers run, test and modify network functions on standard computers and radio equipment. For investors it matters because it lowers the cost and time to prototype and validate wireless services and equipment—think of it as a free flight simulator or recipe book for building cellular networks—so companies using it can move faster, cut development costs and demonstrate new technology to partners or regulators.

Demonstration validates AmpliTech’s commercial-grade ORAN 5G 64T64R MIMO radio in an end-to-end open-stack O-RAN deployment, a landmark for open, interoperable wireless systems

HAUPPAUGE, N.Y., Feb. 25, 2026 (GLOBE NEWSWIRE) -- AmpliTech Group, Inc. (Nasdaq: AMPG, AMPGR, AMPGZ) today announced that its AmpliTech 5G Division and Researchers at Northeastern University’s Institute for Intelligent Networked Systems (INSI), have successfully demonstrated the first open-source prototype of a massive MIMO (mMIMO) O-RAN system achieving O-RAN Category B operation in a laboratory environment. The demonstration integrates AmpliTech’s commercial-grade mMIMO Category B radio unit with the OpenAirInterface (OAI) CU/DU stack, marking the first time a full, end-to-end massive MIMO O-RAN system has been assembled entirely from open, interoperable components.

The demonstration combined AmpliTech’s mMIMO O-RAN Category B radio unit with OAI’s CU/DU into a single cohesive, standards-compliant platform. The INSI team showcased hybrid beamforming capabilities with a 2-layer MIMO configuration, demonstrating sustained throughput under mobility conditions with proper beam management. Critically, it validates that AmpliTech’s radio unit, designed for commercial deployment, can operate at full performance within a fully open, multi-vendor stack.

Massive MIMO systems, which use large antenna arrays to serve multiple users simultaneously through spatial multiplexing, have historically required tightly integrated, vendor-specific implementations. This demonstration challenges that assumption by showing that the full stack, from the physical layer up through the RAN control plane, can be assembled from open, interoperable components, with no reliance on proprietary, closed solutions. Category B is the technically demanding fronthaul interface that enables this at massive MIMO scale, and its successful validation here marks a first for open-source RAN.

"This is a significant step toward making Massive MIMO Open RAN a practical reality rather than a research ambition. Demonstrating that AmpliTech’s commercial massive MIMO radio integrates seamlessly into a fully open-source stack opens entirely new possibilities for how next-generation networks are designed, deployed, and optimized without locking operators into proprietary ecosystems."

— Tommaso Melodia, Director, Institute for Intelligent Networked Systems, and William Lincoln Smith Professor of Electrical and Computer Engineering, Northeastern University

"The O-RAN 7.2 Category B is the interface that truly unlocks massive MIMO at scale, and achieving it with an open-source stack has been a long-standing goal for our community. This demonstration with Northeastern and AmpliTech is exactly the kind of end-to-end validation that turns open-source software from a research tool into a credible foundation for commercial deployment. It shows that openness and high-performance massive MIMO are not in conflict, they are fully compatible."

— Irfan Ghauri, Director of Operations, OpenAirInterface Software Alliance

"This demonstration is a critical milestone for AmpliTech and for the Open RAN ecosystem. Seeing our 64T64R Category B radio operate end-to-end within a fully open-source stack at Northeastern proves that high-capacity massive MIMO and true multi-vendor openness are no longer in tension. This is the kind of validation that gives operators the confidence to deploy Open RAN at scale, and it demonstrates AmpliTech’s commitment to building radios that work in real, disaggregated environments, not just proprietary lab conditions."

— Fawad Maqbool, CEO and CTO, AmpliTech Group

The INSI team led the system integration, testbed configuration, and validation measurements, providing a reproducible reference implementation that academic and industry researchers can build upon. The open-source nature of the demonstration means the architecture can be studied, replicated, and extended, accelerating adoption across the research and operator communities.

The results align with growing momentum around Open RAN and next-generation wireless systems, where flexibility, vendor interoperability, and intelligent control are viewed as essential properties for future 5G and 6G deployments.
