Experimental evaluation of UWB wireless communication within PC case

A novel concept of the use of an ultra-wide bandwidth (UWB) ultra-small-scale wireless interconnect scheme inside an electrically small enclosure is proposed. The concept is presented using a PC tower case as a model environment in which a channel measurement campaign has been made with two different types of antennas. Ricean K factor analysis was conducted for different positions of the antennas to identify the multipath behaviour of the channel, as well as channel capacity. An average maximum channel capacity of almost 6 Gbit/s is achieved using the whole UWB band for one of the antennas, assuming a signal-to-noise ratio of 25 dB. This work supports the proposal that a high-capacity UWB wireless interconnect scheme for communicating different devices within a PC case scenario may be used to replace wired interconnections, providing a wireless backplane system.
