Weidmuller Wireless Ethernet Modem & Device Server WI-MOD-E-G/A User Manual
802.11a (5GHz)
The WI-MOD-E-A utilizes frequency bands within the range of 5.15 GHz and 5.825 GHz. This is broken into 4 distinct U-
NII bands and each region (EU, US, AUS, NZ, etc.) have their own power and operational constraints, see Appendix C for
more details.
The example below shows the US power and operational constraints
"Group 1":
5.15-5.25GHz
"Group 2":
5.25-5.35GHz
5.47-5.725 GHz
"Group 3":
"Group 4":
5.725-5.825GHz
Each frequency band has certain limitations on the amount of radiated power that it can output as well as whether the
band uses what is called "Dynamic Frequency Selection" (DFS), explained below.
