Recommendation to place all antennas 1 to 2 wavelengths from highly reflective surfaces.
2.4Ghz = 4.92 inches (12.5 cm)
5GHz = 2.36 inches (6 cm)
The human head and body attenuates 5db of RF signal
If the antenna is in the body of the phone, the loss ~ 4db – 9db
Handsets do not have diversity antennas due to the length of the 2.4ghz wavelength distance (4.92in)
