**AT&T and Ericsson unveil revolutionary 5G network sensing breakthrough**

**Introduction**
Telecommunications giants AT&T and Ericsson announced a joint demonstration that turns ordinary 5G radio infrastructure into a high‑resolution sensing platform. By embedding radar‑like capabilities directly into the network, the trial showed that existing 5G sites can detect motion, map environments, and even monitor vital signs without adding dedicated sensors. The achievement signals that integrated sensing—a capability long earmarked for 6G—can be delivered today, accelerating a wave of new services for smart cities, industrial automation, and public safety.

**Key Developments**
The proof‑of‑concept leveraged massive MIMO arrays and advanced beamforming to transmit probing signals and analyze the reflected echoes. AT&T supplied a live 5G testbed in Dallas, while Ericsson contributed its AI‑driven signal‑processing engine, which extracts range, velocity, and angle information in real time. During the trial, the system successfully tracked pedestrians crossing a busy intersection, identified a stationary vehicle’s dimensions, and measured subtle chest movements that correspond to respiration rates. All processing occurred within the network core, eliminating latency associated with edge‑computing off‑loads.

**Industry Analysis**
Industry observers note that the demonstration addresses two critical barriers to widespread sensing adoption: cost and deployment complexity. Traditional radar or lidar units require separate hardware, power, and maintenance, whereas the AT&T‑Ericsson approach repurposes existing cellular assets. Analysts estimate that network‑based sensing could reduce capital expenditures for smart‑infrastructure projects by up to 40 % while expanding coverage to areas where installing dedicated sensors is impractical. Moreover, the ability to fuse sensing data with communication
