Government Solutions

A wireless pioneer for nearly five decades, InterDigital engineers design and develop a wide range of advanced technologies used in digital cellular and wireless products and networks, including 2G, 3G, 4G, 5G and beyond. InterDigital is a leader in 5G and beyond research and the source of more than 5,000 contributions to key global standards over the last twenty years.

5G Defense Capabilities

InterDigital is in a unique position to partner with members of the defense industry eager to support emerging U.S. government initiatives around 5G defense development. Our expertise in developing technology at the intersection of wireless and video supports the need for advanced defense communication systems built on 5G standards.

InterDigital’s primary areas of interest for 5G defense deployments include:

  • Physical layer modification to 5G New Radio (NR), deployed as Open RAN technology, for secure communication.
  • mmWave Mesh Networking driven by L2 routing to reduce latency, graceful degradation, and survivability.
  • Edge Compute Emulation Platform for simulating various aspects of 5G defense deployments.
  • Potential to provide complete 5G protocol stack, with partners, for deployment of enhanced NodeB and Integrated Access and Backhaul (IAB) for military nodes.

With a firm commitment to developing and contributing to current and future standards, InterDigital has dedicated a team of more than 20 engineers with expertise in 3GPP standards to drive changes that enable necessary DoD modifications to the air interface that enhance and future-proof the wireless solution.

Government Research

InterDigital has a long history of participation in Department of Defense (DoD) and other government projects, offering keen insights into the technology challenges faced by defense systems. In 2009, InterDigital was responsible for delivering part of the 3G protocol stack, and today leads cutting edge 5G research projects. Over the years, InterDigital has contributed to multiple government projects as a sub-prime contractor and commercial off the shelf (COTS) supplier. Today, our focus is centered on open source 5G solutions that align with the Department of Defenses’ 5G initiatives.

InterDigital’s government research projects have included:


US Army Research Project (CERDEC)


InterDigital was the prime contractor responsible for designing and prototyping 3GPP commercial technology for dual use operation in 1350 MHz and 1390 MHz and commercial bands. Due to reduced duplex spacing, the RF front end (transmitter and receiver) was redesigned for low noise and high-power amplification.


US Navy’s Mobile User Objective System (MUOS)


This program deployed a constellation of satellites that provided narrowband ultrahigh frequency (UHF) communications to mobile and fixed-site users worldwide. InterDigital served as the sub-prime contractor, as well as COTS supplier to General Dynamics, the primary contractor for communication technology.  InterDigital contributed modified WCDMA (HSPA) technology for mobile and fixed users.


SBIR - Emulated LTE Analysis Environment (Phase I, Phase I Option)


InterDigital developed an emulation system capable of deploying a full Long-Term Evolution (LTE) 5G architecture that uses open-source software, into a self-contained personal computer for Extendable Mobile Ad-hoc Network Emulator (EMANE). The project experiments with utilizing LTE for tactical communication under varying scenarios and conditions.


SBIR mmWave for Army Tactical Comms (Phase I)


InterDigital researched and developed cost effective communication systems for use in Anti-Access and Area Denial (A2AD) environments. The solution utilized novel waveforms and techniques that operate in the mmWave frequency band in both stationary and on-the-move (OTM) conditions.


SBIR - N192-128 Clipping Reconstruction (AIRIS)


This project produced a simulation study of the reconstruction of wireless signal (clipped ADC samples) using AI/ML algorithms to reconstruct signals damaged by non-linear distortions. This project initially targeted applications like Pilot contamination in massive MIMO, the act of reconstruction due to short bursts of interference or missing data, and the repair of non-linear distortions in transmitter and receiver.
