HOW DKT WAVE2 USE THE 2.4 AND 5 GHz FREQUENCIES

t is always clients (Smartphones, iPads, PCs, other wireless equipment) that ”decide” which wireless band is to be used. In other words, clients decide if they want to access Wi-Fi mesh units on the 2.4GHz or 5GHz band. This means that the Wi-Fi mesh unit cannot move the client between bands. However, clients are automatically moved between channels on the 2.4GHz and 5GHz bands. DKT Wi-Fi mesh units have built-in intelligence to optimize which clients will be placed on specific channels.

2,4 GHz channels: ch. 1 … 13
5 GHz channels: ch. 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140

DFS channels are marked with green

Note that in accordance with national regulations in certain countries, a large part of the 5 GHz Wi-Fi channels can only be used by units that employ a function termed Dynamic Frequency Selection (DFS). This ensures that Wi-Fi equipment does not disturb radar installations. Because Wi-Fi mesh units must determine whether there are radar units in the vicinity, a scan of all frequencies is performed. This is time consuming and can take 10 minutes upon startup.
At the outset, the DKT Wave2 Air model has the DFS channels shut, which means that only channels 36, 40, 44, 48 are used on the 5GHz band and that clients and back-haul traffic between units only use these four channels. This is to raise the user experience upon startup. DKT Wave2 PowerLine will at outset support all channels.
Contact the manufacturer if this needs to be modified.
