I have an interesting dilemma. I use my Sprint Touchpro2 as a modem to provide my netbook and ipod touch with internet access at the office. I work in an office that has large windows, almost floor to ceiling approximately 9 feet high. My office is separated from these windows by a drywall partition about 6 or 8 feet away and my desk is about 12 to 14 feet away from that wall. While downloading file to my computer with the phone at my desk my bandwidth is about 4 to 8 Kb/s if I go by the wall it increases dramatically to 40 to 50 Kb/s if I go by the window bandwidth increases to 90 to 110 Kb/s. I have never seen such a large drop in bandwidth over such a short distance. I am assuming it's some kind of interference but what. Wifi operates at 2.4 and 5.0 Ghz. Cordless phones usually 900 Mhz and 2.4/5 Ghz. But my office doesn't have any of those. What else could produce interference in the 1.9 Ghz spectrum.
