2400-2500MHz radiation characteristic
Main antenna
- Notebook operation mode
- Tablet operation mode
Note1) The measurement was performed at 3 frequencies (2400, 2450, 2500MHz).
Note2) The maximum antenna gain was found around 260 degree angle from measuring apparatus in
Vertical polarization at the middle frequency (2450MHz) of Tablet operation mode.
