ABSTRACT Mobile phones or portable Hand Set (PHS) use the combination of wireless communication and optical fiber communication. Microwave power transistors play key role in today‟s wireless communication. HEMT is finding wide application due to its high speed. Analytical results for various DC parameters under the optical illumination are presented. The photovoltaic effect at the gate junction...

Optical wireless communications offer a viable alternative to radio frequency (RF) communication for indoor use and other applications where high performance links are needed. These systems use infrared technology (IR), which has significant advantages over RF. This paper presents a review of the most significant issues related to infrared communication technology, which will enable the realiza...

Optical wireless communication (OWC) technologies have been discussed and evaluated in a wide range of application scenarios, which is drawing increasing interest to keep pace with the growth in LED technologies. OWC has unique advantages to provide safe, secure, low-cost, and high-bandwidth communications. As a compensation for the existing radio frequency communications, OWC has huge potentia...
