FCC: 

The maximum calculated MPE ratio for the EUT with 3 dBi dipole antenna is 0.259 (evaluated at 45 cm), this 

configuration can be co-located with other antennas provided the sum of the MPE ratios for all the other 
simultaneous transmitting antennas incorporated in a host device is ≤ 1.0 - 0.259 ≤ 0.741. The following co-location 
were evaluated for mobile configurations:  
 

Industry Canada:
