Measurement and characterization of ultra-wideband wireless interconnects within active computing systems

This paper presents experimental measurements of ultra-wideband (UWB) wireless interconnects within an operational computer system chassis. Using an impulse-radio ultra-wideband (IR-UWB) 3-5GHz transceiver, this paper analyzes and verifies the implementation of high-bandwidth wireless communications within an enclosed, heavy multipath, metallic environment such as a computer server chassis. Bit-error-rate (BER) and recovered clock jitter were measured at various positions within the computer chassis. The results show a 6X improvement in BER after applying the equalizer to the noisy channel while the motherboard is fully operating.
