Abstract
A novel high-speed optical wireless communication system incorporating wavelength
division multiplexing technology for indoor personal area networking applications is
proposed in this paper. Even with the simplest single wide field-of-view (45°)
nonimaging receiver, bit rate as high as 4 x 12.5 Gb/s has been successfully
demonstrated by experiments. It is shown that error-free reception (bit error rate <
10<sup>-9</sup>) can be achieved over the entire beam footprint of about 1 m, so
limited mobility can be provided to subscribers. In addition, a new localization system
based on this optical wireless communication system has also been proposed and verified
by experiments. When these two systems are incorporated together, high-speed optical
wireless communication with mobility feature can be provided to users over the entire
room.
