Technology Presentation on White LED Broadband Edwin “Doods” Capili EcE 303 Research Seminar 3 December 22, 2007

Technological Insight White LED for room light & communication <100MHz Transmission

Significance in the Market Economical: (1) Functions as room lighting & wireless communication; (2) Low power consumption Easy to install: Piggybacks on existing room lighting system Security: Data signals cannot pass through walls

How to Adapt in the Philippines Technical issues: Design of uplink Design of uplink Negative effect of natural and artificial light Negative effect of natural and artificial light Balance between lighting and communication Balance between lighting and communication Optical sensors may be more effective on certain light wavelengths that the human eyes may not react as effectively Optical sensors may be more effective on certain light wavelengths that the human eyes may not react as effectively Would be useful after solving the “last mile” problem delivering connectivity from provider to a customer in an economical way. delivering connectivity from provider to a customer in an economical way.
