DOCOMO and Abside Networks Sign Memorandum of Understanding on HAPS

- Joint Study on AI-Driven HAPS Communications Technologies -

BOSTON, MA, UNITED STATES, October 13, 2026 /EINPresswire.com/ -- NTT DOCOMO, INC. and Abside Networks, Inc. signed a memorandum of understanding (MOU) on October 13, 2026, toward the development of future communications infrastructure utilizing high-altitude platform stations (HAPS*1) and realizing of next-generation networks leveraging artificial intelligence (AI). Going forward, the two companies will conduct joint studies toward future collaboration in areas including wide-area, high-capacity and massive-connectivity communications using HAPS, network control and data utilization.

Background
DOCOMO has been conducting studies and demonstrations toward the realization of wide-area communications services utilizing HAPS. To deliver high-quality communications services via HAPS, it is important to develop radio access networks (RANs) and communications equipment suited to the stratospheric environment. As conditions in the stratosphere differ from those on the ground, communications equipment and network design must be adapted accordingly, requiring specialized knowledge and experience.

Abside has many years of experience in stratospheric communications. Through Project Loon*2, Abside developed knowledge and experience in stratospheric communications and has been engaged in the development of HAPS communications equipment and RAN technologies. Abside is also developing non-terrestrial network (Non-Terrestrial Network, NTN) technologies and AI-based network control technologies.

As a result, the two companies confirmed that their respective visions and technologies may be complementary and signed the MOU to jointly explore potential future collaboration toward networks that integrate the ground, stratosphere and space.

Scope
Under the Initiative, the two companies will jointly study technical collaboration for the future use of HAPS. The principal areas of study are as follows:

-System architectures for wide-area, high-capacity and massive-connectivity communications using HAPS
-Application of AI to demand forecasting and the control of beams, capacity, spectrum and interference in stratospheric RANs
-Collection and utilization of data relating to communications quality, network operations and sensing in the stratosphere
-Future integration with external applications and service platforms

Future Outlook
DOCOMO is independently studying a future network vision based on a three-dimensional communications infrastructure that integrates AI with NTN initiatives, including HAPS. The vision aims to address growing communications demand accompanying the expanding use of AI by realizing wide-area, high-capacity communications and advanced network control using NTNs, including the stratosphere, in addition to terrestrial networks. Its realization will require RAN and network orchestration technologies capable of integrated control across terrestrial networks (Terrestrial Network, TN) and NTNs.

Abside is developing radio equipment for TN and NTN RANs that uses a large number of antenna elements (Very Large Array) to enable high-spatial-resolution and precise beam control Abside is also developing an AI-driven software platform that provides integrated control of networks across the ground, stratosphere and space.

Going forward, the two companies will bring together their respective expertise and technologies and pursue joint studies toward the realization of next-generation communications infrastructure utilizing HAPS and AI.

*1. Unmanned aerial platforms that operate in the stratosphere at an altitude of approximately 20 kilometers. By equipping the platforms with wireless communications equipment, HAPS is being studied as a means of providing coverage in areas that have traditionally been difficult to serve, including airspace and maritime regions, as well as underserved locations such as sparsely populated and mountainous regions where conventional coverage has not been economically viable.
*2. A stratospheric communications project led by Google that sought to provide communications services using high-altitude balloons. For more information, please visit: https://x.company/projects/loon/
*3. AI 3D Networks, AI3DN™, is a vision central to 6G deployments of a single AI-driven network spanning terrestrial, stratospheric and space-based layers, built on the high-spatial-resolution foundation of Abside's AI3DR™ RAN product lines.
