The new generation of laptop and pen computers will require wireless c
onnectivity to fully exploit the potential of personal mobile computin
g. They are also likely to require broadband telecommunications servic
es for video transmission and access to multimedia databases. The use
of the optical spectrum for wireless communications avoids radio frequ
ency planning constraints, and can provide almost infinite bandwidth f
or these future applications. This paper describes enabling technologi
es that enhance the range, speed and practicality of optical wireless.
