M14A2A  User  Manual  

This device is intended only for OEM integrators under the following conditions: 

(1) The antenna must be installed such that 20 cm is maintained between the antenna and use rs,    

(2) The transmitter module may not be co-located with any other transmitter or antenna. 

(3) To comply with FCC regulations limiting both maximum RF output power and human exposure to RF 
radiation, the maximum antenna gain including cable loss in a mobile exposure condition must not 
exceed: 

Standalone Condition:

 

    10.1 dBi in 700 MHz Band 

   

6.5 dBi in 1700 MHz Band 

   

9.5 dBi in 1900 MHz Band 

Assuming collocated with a WLAN transmitter with maximum 34 dBm average EIRP power

 

   

7.0 dBi in 700 MHz Band 

   

6.5 dBi in 1700 MHz Band 

   

9.5 dBi in 1900 MHz Band 

Remark: This assumption is not valid if the output power of the collocated WLAN transmitter is higher 
than 34 dBm.
