We propose a free-space optical system to replace wireless LAN in commercial and residential premises. This system is not only able to integrate with inter-continental optical trunk fibres, but also with future high-speed optical computer processors which are now being developed by IBM. Closing the last mile using wireless optical (WOP) communication provides the advantages of a cableless environment, mobility freedom, and faster data transfer rate. Trunk optical signals from the metropolitan

Photoreceivers, on the other hand, absorb light signals and convert them back to electrical signals for the devices. Since light has become the medium of communication, a few devices have been proposed so that transmission and reception of optical signals are optimized. Protocols have also been proposed for data efficiency and security. Besides domestic and office uses, the WOPCOM system can also be used in ships and airplanes to communicate internally. In the next wave of communication devices, superdiodes (or ultra-highsensitivity solar cells) can be used to receive such optical signals outdoors.
