Recently, mobile communication system and fixed wireless access communications are rapidly grawing. Also the photonic network for broadband fiber access communications is being researched and developed now. Synergy of these developing technologies produces the microwave photonic (MWP) technologies, and these new technologies are now put into real use. This paper reviews the MWP technologies and systems. Also it introduces the Virtual free Space Network (Radio High-way Network) which is researched in our LAbs.
