Wayne Tower, Applied Sciences Division. Lucius Fox took out a watch-like device and handed it to Bruce Wayne.
"The latest design in radio signal trackers. You can track and analyze any phone call from twenty or thirty meters away. Of course, it's also a very powerful satellite phone. It'll come in handy when you go skydiving, cave exploring, or camping in the rainforest." Lucius introduced it, though that last addition seemed rather unnecessary.

In fact, I don't think anyone in the entire United States can manufacture it." Lucius was full of admiration.
Bruce Wayne hesitated for a moment before putting the watch on. Then he said, "Luo Xia really is an unusual friend."
As night fell over Gotham City, every kind of crime began running rampant. Bruce Wayne put on the improved first-generation Batman armor and silently arrived outside Gotham City Police Department.

Countless radio waves reflected and traveled through the air—not only cell phone signals, but also television, radio broadcasts, and electromagnetic waves produced by fluctuations in transformer currents.
The chaotic signals were separated one by one on Bruce Wayne's watch. An ordinary chip simply could not handle that kind of enormous processing load.
