As electronic devices become smaller, lower in power requirements, and less expensive, we have to adorn our bodies with personal information and communication appliances. Such devices include cellular phones personal digital assistants (PDAs) pocket video games and pagers. Currently there is no method for these devices to share data. Networking these devices can reduce functional I/O redundancies and allow new services and conveniences.

The concept of Personal Area Networks (PANs) is presented to demonstrate how electronic devices on and ne ....etc

However, this could be accomplished only after considerable research in high speed aerodynamics and ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc
