Congrats on a great product! Just started reading about the imp.
I know there are many variables, but with the built in antenna, assuming clear Line of Sight to the Access Point, what is the expected WiFi range? Is there a datasheet somewhere that describes the hardware characteristics?
Spec sheet is on the wiki: http://devwiki.electricimp.com/lib/exe/fetch.php?media=imp_spec_sheet_aug20_2012.pdf
…we’ve seen 85m with an april and an apple airport extreme AP (not all line of sight), and over 250m with a ubiquiti airgrid 2.4 AP… though that is a tad directional
FWIW, my Imp WiFi range is better than that of my Eee Netbook PC
