A new configuration of broadband wireless access in heterogeneous ubiquitous antenna and its experimental investigation

Recently, multi-antenna technology is used in almost new wireless radio communi- cation technology such as MIMO (multiple{input multiple-output) towards high throughput and high reliable communication (1{3). The heterogeneous wireless networking is required to achieve high data rate and wide area coverage. The Radio on Fiber (RoF) is one of the candidates to construct \Wireless Cloud" infrastructure with low cost (4,5). This paper proposes a new conflguration of broadband access network for heterogeneous radio which is based on distributed antenna system (DAS) (10{12) over the wavelength division multiplexing-passive optical network (WDM-PON) (6,7). A fundamental experiment is conducted for the performance evaluation in physical layer.
