PTCRB Requirements Note
There cannot be any alteration to the authorized antenna system. The antenna system must be the same type
with similar in-band and out-of-ban radiation patterns and maintain the same specifications.
with similar in-band and out-of-ban radiation patterns and maintain the same specifications.
FCC Requirements Note
The antenna gain, including cable loss, must not exceed 3.0 dBi at 1900 MHz / 1.6 dBi at 850 MHz for mobile
operating configurations and 7.0 dBi at 1900 MHz / 2.3 dBi at 850 MHz for fixed mounted operations, as
defined in 2.1091 and 1.1307 of the rules for satisfying RF exposure compliance.

Load Balancing
The MVPGSM uses round robin load balancing to ensure that one or more SIMs are not used excessively while
others go largely ignored during times of light traffic. The channels are treated as a list and once a channel is
used, it goes to the bottom of the list and the next channel comes to the top of the list and is ready for use. In
the case of a MVPGSM-2, once channel 1 has been used, the next call will be routed through channel 2, then
back to channel 1, and so on. When Hunting is enabled, load balancing is done automatically.
