5.6.3 Antenna-Gain and Radiation Pattern
If BlueMod+S42/AI is integrated into an end product while the recommendations depicted in
6.4 Placement Recommendation are maintained, the following typical antenna radiation
patterns can be expected.
Radiation Pattern will depend on the end products PCB size, masses in the antenna
environment, housing material and geometrics. Typical antenna gain is about +2dBi.
Antenna patterns will be updated in final document
