Zusammenfassung:An optical communication system is provided for hand holdable computing devices. The optical communication system facilitates the data communication distance of the hand holdable computing device by using electromagnetic radiation between 200 nanometers and 1500 nanometers to pass data. The radiation is generated by the system using light emitting diodes or one or more lasers. The system is optically coupled to the infrared data communications port an existing hand holdable computing device or is electrically integrated into the computing device. Once coupled, the system allows the hand holdable computing device to communicate with remote optical communication devices up to 1000 meters away. The system finds application with personal digital assistants, cellular telephones, and portable computers.
