{2452.5 MHz; 2453.5 MHz;….2468.5 MHz }
The hopset has to be chosen to reduce interference with other radio equipment in 2.4 GHz frequency band.
For example, if a Wifi access point is configured at channel 6, the frequency band of the access point is 2426MHz-
2448MHz. Thus, the 2405-2422 hopset and 2452-2469 hopset have no interference with this Wifi access point.

Set Radio Security Keys :
Use the Hop Sequence and the Synchro Word keys to secure the WTU-518 network.
Use the Hop Sequence key to limit the interference with another Sercel network. The Hop Sequence key defines a
unique frequency sequence. Two different Frequency keys define two frequency sequences, using the same set of 17
frequencies but correlation between the two different sequences is about null.
