This paper proposes a concept for superluminal communication through the neighboring brane A1 within the framework of the Infinite-Dimensional Multiverse Model (IDMM). According to the IDMM, our Universe is a 3-brane dividing the surrounding bulk space into two half-spaces. On the first-order w-axis, a neighboring universe A1 is predicted at galactic coordinates l≈120°, b≈–30°. Conventional radio communication with spacecraft at Jupiter suffers from a one-way delay of 33–53 minutes due to the finite speed of light, making real-time rover control and rapid command transmission impossible. Hypothetically, if one could construct a device capable of modulating the physical vacuum in the direction of A1, information could be transmitted not across our Universe’s space but through the extra dimension — via a “bypass route” through the brane. The theoretical delay would shrink to microseconds or milliseconds. The paper reviews existing theoretical work, including a very recent publication by Benakli (2026) that first proposed using the Kaluza–Klein tower as an information bridge between neighboring branes. The uniqueness of the proposed concept lies in linking FTL communication to specific, experimentally testable directions A1/B1 derived from CMB anomalies, in offering an engineering formulation (modulator, antenna, receiver), and in focusing on a practical application — communication with Jupiter‘s satellites. This document establishes the author’s priority for the concept. It contains no engineering details sufficient for commercial implementation and invites physicists and engineers to collaborate on a voluntary basis.
