3/21/06     Preliminary Results > Cellular band

As of now, the group has been able to successfully connect a single Comblock to the network and run the software.  Our preliminary data was of Cingular in the cellular range (see graph 1 & graph 2), the lower portion of the graphs show the PSD, while the upper regions show time versus frequency.  In the time versus frequency portion of the graph, the red represents used channels, while the yellow represents unused channels.  These graphs are significant to our project because the group can distinguish between the used and unused channels very easily.  Eventually, when multiple Comblocks are connected at various locations around campus, the group will be able to observe the channel usage dependence on location.
