Comparative Study of Commercial LEDs and PINs for Wireless LANs

Abstract

This paper presents the available devices (LEDS and PINS) from several manufacurers. The study has been made with a database from 40 manufactures and it include 660 light emitting diodes (LEDS), 439 pin-photodiodes (pIN) and 165 laser diodes (LD). This database will be presented in the next meeting. The most useful LEDs for wireless LANs are few. Only four manufacturers present LEDS with rise and fall times less than IOns and radiant power greater than 10 mW. Large and fast photodiodes (active area greater than 100 mm2 ) are manufacured only by two.
