Three stations are allowed on frequency, one transmitting at a time
Three subcarriers are permitted, subcarrier one is being used
Three digipeater hops are requested with one remaining✓Bonne réponse
Three internet gateway stations may receive one transmission
Explication
In the WIDEn-N path convention the first digit is how many digipeater hops the sender asked for and the second is how many are still available, so WIDE3-1 was launched with three hops and has two behind it and one to go. Nothing in the notation concerns subcarriers, channel sharing, or gateway counts.
