Tesla wins FCC approval to use UWB for Cybercab wireless charging
Published on: Mar 6, 2026
The decision moves Tesla closer to creating a fully cable‑free charging ecosystem for its autonomous fleet.
The US Federal Communications Commission (FCC) has granted Tesla a key waiver allowing the company to deploy ultra‑wideband (UWB) radio technology in its planned wireless charging system for the Cybercab robotaxi. The decision moves Tesla closer to creating a fully cable‑free charging ecosystem for its autonomous fleet.
UWB signals are typically restricted to portable devices and are not permitted in permanently installed outdoor equipment. Because Tesla’s wireless charging pads will be fixed to the ground, likely at homes or dedicated charging hubs, the company required special federal approval. According to its FCC filing, the UWB system operates at extremely low power and is active only while the vehicle is parked, with the car’s metal body blocking most emissions once aligned.
Tesla plans to use Bluetooth to initially locate the charging pad, switching to UWB as the Cybercab approaches. The high‑precision positioning enables the vehicle to center itself over the inductive pad before wireless power transfer begins.
The approval comes just days after the first production Cybercab rolled off the line at Gigafactory Texas. The two‑seat electric robotaxi, built without a steering wheel, pedals, or mirrors, is designed for fully autonomous operation, cleaning, and charging.
