ePMP 4600 Frequency range vs 4625 SM

I am in the FCC region. Why can the ePMP 4600 AP broadcast on a larger range of frequencies than the 4625 SM can connect to?

The 4600 AP lets me choose between 5745-6865mhz which looks be the UNII-3, 4, 5, 6, and 7 bands while the 4626 SM only can connect to 5955-6865mhz which is only part of the UNII-5 all the UNII-6, and 7?

Band Frequency Limits Bandwidth (MHz)
U-NII-3 5.725-5.850 125
U-NII-4 5.850-5.925 75
U-NII-5 5.925-6.425 320
U-NII-6 6.425-6.525 320
U-NII-7 6.525-6.875 320

Hello @terintamel,

it is by design.
Force4600C can do 5745-6865 mhz as well. It is more expensive model with more capabilities compared to Force4625.
