“…DWDM could be applied using multiple optical mm-wave sources, but a particularly attractive approach is the optical mm-wave/DWDM overlay shown in gure 5. In this approach, radio subcarriers are applied directly to DWDM sources, the multiple wavelengths are multiplexed and the composite signal is upconverted to mm-wave frequency using a Mach{Zehnder modulator (MZM) to perform suppressed optical carrier (SOC) modulation (Sauer et al 1998;Gri¯n et al 1999a). This approach allows the use of standard DWDM sources, can span tens of kilometres of standard single-mode bre, and employs only a single high-speed modulator/driver/local oscillator.…”

There has been a remarkable take up of wireless and mobile communications in recent years, such that in a number of countries the number of mobile phones now exceeds the number of xed network connections. Alongside this, we are seeing dramatic growth in data on the network compared with voice: the so-called`data wave'. While much mobile network tra¯c is currently voice there is increasing use of the available data facilities with these now being enhanced (e.g. via evolution of the global system for mobile communications and subsequently the introduction of`third-generation' systems such as the universal mobile telecommunications system). Accordingly, there is considerable interest and activity in the research community concerning possible technologies exploiting yet higher frequencies where truly broadband future wireless networks may be realized. This paper will review some of the technology options currently available or under examination for millimetre-wave broadband wireless networks and will go on to consider in some detail a speci c example of` xed-wireless' technology synergies exploiting radio-over-bre techniques to achieve ®exible, recongurable broadband wireless networks.

“…Further significant cost reduction can be achieved, if a wavelength division multiplex (WDM) system is applied, since optical amplifiers can be used by all channels. We proposed and demonstrated an optical mm-wave transport system applying simultaneous upconversion of the individual data signals at IF range in each WDM channel by a single high-speed electro-optical modulator @OM) to mm-wave range [4]. Initial experiments at 60GHz were carried out at a channel spacing of 200 GHz, however, we also demonstrated a 7 channel experiment with a spacing of 100 GHz [5].…”
