AnySignal and Andrenam Partner for Underwater Communications Modem

LOS ANGELES, Oct. 9, 2026 /CourierPR/ -- AnySignal and Andrenam have announced a strategic partnership aimed at revolutionizing the underwater communications landscape by bringing to market a new family of underwater acoustic communications modems. The companies, both leaders in their respective fields of distributed maritime platforms and resilient radiofrequency (RF) communications capabilities, are combining their expertise to develop a cutting-edge modem that will be available for broad market integration in the first half of 2027.

The partnership leverages AnySignal’s core modem and communications technology, which it has previously applied to its Terramodem, flight-proven communications terminals (AstroModem USX), and network orchestration software (AnyLink). This core technology will be integrated with Andrenam’s existing underwater operating experience, its network of intelligent surface platforms, and its consistent access to maritime test environments. Andrenam’s PEARL buoys, which connect to underwater vehicles and sensors, will serve as a critical link in the communication chain, providing compute, communications, and sensing infrastructure for the maritime domain.

AnySignal will take the lead in developing the core modem and communications technology, while Andrenam will contribute its extensive experience in underwater operations, its existing government customer relationships, and its consistent access to maritime test environments. Together, the companies aim to extend the acoustic modem into a comprehensive acoustic-to-radio frequency (RF), seabed-to-space communications architecture. Underwater assets can communicate acoustically with distributed surface nodes, such as Andrenam’s PEARL buoys, where data can be processed locally or routed through resilient satellite and terrestrial networks like AnySignal’s AnyLink network.

The companies are expecting early modem shipments in the first half of 2027. The acoustic modem is intended to be the first product from a broader technical partnership. Andrenam’s distributed surface platforms can host communications, compute, radar, SIGINT, ELINT, acoustics, electronic warfare, and other payloads. AnySignal’s full stack platform, encompassing on-orbit radios, ground stations, and global networking, brings proven expertise across corresponding mission areas, creating opportunities for additional distributed maritime sensing and processing products over time.

AnySignal is a U.S.-based aerospace and defense technology company building the operating system for the electromagnetic spectrum. The company designs, builds, integrates, and operates end-to-end radio-frequency (RF) systems for civil, commercial, and national security customers to sense, connect, navigate, and defend across land, air, sea, and space, providing the adaptable capabilities their missions depend on.

Andrenam is a Los Angeles-based dual-use technology company delivering persistent, passive acoustic monitoring for maritime domain awareness. Its PEARL networked buoys and OBSIDIAN software platform turn underwater audio into actionable maritime intelligence for defense, homeland security, critical infrastructure, and commercial maritime customers. Andrenam deploys and operates distributed sensor networks so customers can buy persistent coverage rather than another complex system to own.
