In this paper, we analyze the measurement of ultra
wideband (UWB) noise channels in different indoor
environments. All measurements are done using a vector network
analyzer (VNA) which allows us to measure the noise channel
transfer functions. We find that the noise power of the system is
decreased by increasing the intermediate frequency (IF)
bandwidth which leads to an increase in time taken to perform
measurements of the channels. Also, we measure the
environmental noise power and find that it is slightly affected by
fluorescent light sources inside the measurement environments.
In addition, we find that the environmental noise is decreased
when enclosed in a Faraday cage (steel shed), within an intense
multipath measurement environment. As secondary application,
we show how a frequency detection device can be used to readjust
a maladjusted frequency selection on a remote controller
for a garage door, in presence of environmental noise power.
