Hi! My 7th grade son is working on the "Point of a Parabola" project, but we aren't able to find a site that measures in dBm. Using the materials page, we were able to find and download one that measures, among other things, RSSI and "Signal Quality." Not sure if we are proceeding incorrectly because the RSSI numbers were the only ones that changed much during our trials. Are those ok to use?. Also, in order to stay in the same room for testing, we are only at a distance of 2.5 meters. Please help quickly if we are doing this wrong... his data analysis is due next week!
Thanks

Re: Parabola and wifi strength measuring
Hi Hazelkim,
RSSI stands for the “received signal strength indication”. It is a relative scale, usually from 0 to 100, indicating the strength of a wireless network signal. More details about the RSSI are here:

The RSSI values should be OK to use for your project. When testing at a 2.5 m distance from the signal source is the RSSI value ever “maxed out”? If so, you should move farther away even if you have to go into another room. As pointed out in the project procedure it's OK to move into another room but you must use the same location for the measurement device for all of the testing.
I hope this helps. Please ask again if you have more questions.
