2.4 GHz Module Channel Selection - nRF24L01 – RF_CH Register
| Channel | Frequency (Mhz) | Description |
| 0 to 82 | 2400 to 2482 | Legal, but noisy (conflicts with wireless LAN, Bluetooth, etc.) |
| 83 to 99 | 2483 to 2499 | Not legal for mobile |
| 100 | 2500 | Licensed in BC to Inukshuk Wireless |
| 101 to 119 | 2501 to 2519 | Legal |
| 120 to 125 | 2520 to 2525 | National and regional systems (Department of Defence, Telus) |
I have discovered that not all the channels this module is capable of using are legal, not to mention suitable. Noise, traffic (blue tooth, wifi, cordless phones, etc.), play a vital role when picking channels to use. According to this page nRF24L01 – RF_CH Register the suitable channel range is 101-119. This cuts options down quite a bit considering that each pair will need a channel. Still, 18 pairs/links is more than enough for what I am doing, for now anyway. If this pool size looks like it will be breached, I will have to get creative on channel assignments.
