[ubuntu] wireless - iwlist scan - what are cell

I using the 'iwlist' tool to get details about the wifi landscape at my location; however, I noticed items called 'cell'. Some of these cells have bogus mac addresses, and do not show SSIDs. Are these cells the radios from my router? For example: My ssid shows up as 'cell 01'; however, 'cell 02' and 'cell 03' are on the same channel as my SSID and signal strength and SNR are the same, but there is not listed SSID.

Just not sure how to read the iwlist output. Thank you
