Hi Marcus, 1. Point is, how do you *know* there's been no transmission? Where you in an RF-tight room and switched off all your bluetooth devices, smart phones, wireless door bells, wireless thermometers, RC car controls, wireless door openers, remote controlled power outlet switches, wireless keyboards & mice, wireless headphones... just to name the 2.4GHz ISM-band devices that pop into my head right now. ==> Nothing , I am at palm oil plantations, Please see page 70 2. What document? What details? ==> Attached technical analysis in 84 pages ; https://mega.nz/#!YwplVCCT!Acbe00paHk3dLJuf04B5zSBifSw0-bHz5IciiNLgQwY Regards Srinivasan T From: Marcus Müller [mailto:address@hidden Hi Srinivasan, On 11.02.2016 05:11, Srinivasan T wrote:

Waterfall Pattern also dfferent. Many people not sure about 2.4 GHz. in 84 pages document, I have checked all details . What document? What details? |
