Weekly status:

Include discussion of what you accomplished this week, who you contacted, what decisions were made, what obstacles were identified, how they are being addressed.

· This week we completed and handed in the spring interim report. We were able to take care of the graph problem we were having last week. We had to reset the registers of our COM blocks in order to get accurate graphs for the desired frequency ranges.

· We took data in the Wireless lab, in the library, and in the computer center. We found that the data was different for each area, which is what we expected. The best data we took was in the computer center. They were all taken within the same frequency range of 870MHz to 879 MHz.

· The data we captured in the Wireless Lab had a wide red band in it which we thought was due to the interference of all the other apparatus in the lab. We still think this is the case, since in the computer center this band was nonexistent.

· One problem we're having now is saving the data. In one run, if we choose to run the loop 35 times, we can only save the last graph. We want to be able to save all the graphs so we can look at the differences in the spectrum for a run of a couple of seconds. Two of our team members were able to get the code to save the data, but when we tried to open the graphs we couldn't. So, we are still working on that problem and I am sure that by this week we will have that solved.

· We plan to take more data with the Cellular Com block at the beginning of this week and then we want to move on to the PCS Com block. We also hope to be able to put a few com blocks in different areas and capture their data simultaneously.
