摘要

Wireless networks are currently replacing connection cables via radio, visible or infrared waves. Modules and base systems are installed to cover zones in relation to a quality of service and availability. There are technological radio solutions: Bluetooth, WiFi, UWB and optics constituted by infrared or visible systems. Optic technology has important advantages: Transmitted data security, radio and medical immunity, etc. Nevertheless, optical systems seem to present a limit because this is basically a line of sight solution and the network management is based on only one wavelength with several users. The solution suggested, in the scope of this document, is to transmit various wavelengths in free space, using optical Multiplexer/Demultiplexer and optical modules, which are compatible in wavelength. Each Emission/reception module could have a defined and personal wavelength, with a link with the terminal identification (MAC address for instance). This approach can improve and give a full duplex data rate with a minimum of a dozen Mbps per user for broadcasting. The application field for the suggested system is potentially included in the following network types: Optic WLAN and Optic WDAN.
