The following snmp object can be used to configure the radio mode on the PMP 430

Antenna Gain
Comparing the SM antenna gain and augmentation options for a PMP 430 SM and a PMP 450 SM, the PMP
430 SM has higher gain.
The integrated antenna gain of the PMP 430 SM is 10 dB vs. 9 dB of the PMP 450 SM.
The additional gain provided by the LENS for a PMP 430 SM is 6 dB vs. 5 dB for the PMP 450 SM.
The additional gain provided by the Dish for a PMP 430 SM is 15 dB vs. 14 dB for the PMP 450 SM.
If a PMP 430 network is upgraded to a PMP 450 network, users with PMP 430 SMs will experience a lower
system gain when the PMP 430 SM is replaced by a PMP 450 SM. This lower system gain may change the
modulation mode used for communication to a lower (more robust) mode, but it does not necessarily result
in a lower throughput, because the PMP 450 SM is capable of communicating in MIMO mode.
Sensitivity
For each modulation mode, the PMP 430 system has 3 dB lower sensitivity values than the PMP 450
system, as shown in the following table.

Setting the variable to 1 will reboot the unit. When the unit finishes rebooting, it will be in
finishedReboot state. PMP430 SM only.
