Take for example a small room with no people in it, you are trying to hold a conversation with someone across the room, you’ll probably need to be standing within 4-5 meters of that person for them to be able to hear you speaking at a normal level. Now, consider being in the same room but instead filled with 20 people talking at once, you’ll need to be much closer than a meter for that same person you were trying to hold a conversation with to hear you speaking at a normal level, reducing the distance between you.
Think of yourself as the transmitter, your friend the receiver, your speaking voice the signal and all the other people speaking around you to be the ‘noise’. The greater the ‘noise’ level (other signals in the 2.4Ghz spectrum), the closer the ‘transmitter’ and ‘receiver’ will need to be to successfully communicate with each other.
Of course, there is technology that can help with the background noise. Each RØDELink system transmits on two frequencies simultaneously and its series II 2.4Ghz technology is constantly searching for and hopping between the strongest frequencies to transmit on, ensuring the best possible communication between transmitter and receiver. However, understanding that the 2.4Ghz ‘noise’ will affect the range which the RØDELink systems can transmit will help ensure you allow for the best setup within your requirements.
