January 2010 doc. : 11 -10 -0011 -0000 ad Radio over Fiber in the Home Area Network • The wireless connectivity is generally preferred for the final link to the device (easy to use and very flexible). • In the future, IEEE 802. 11. ad will be the radio standard to transport data at very high throughputs (above 1 Gbps), • But, this radio standard has a short range (less than 10 m). How can we enlarge the coverage of the radio signal ? Submission J. Guillory, Slide. S. 5 Meyer & B. Charbonnier, Orange Labs

doc. : 11 -10 -0011 -0000 ad January 2010 Radio over Fiber in the Home Area Network • So, the Radio over Fiber system enlarges the coverage of the radio signal itself. It consists in transporting the radio signal from wireless devices onto an optical carrier for distribution over optical fibre to different remote antennas. The optical link acts as an analogue repeater. • Transporting the radio signals in their native format, provides the advantage of remote antenna simplification and transparency to radio layer protocols.
