So can you use radios in critical environments where in-band or out-of-band interferers may be present? The answer in most cases is yes, as long as you have a good data protocol in place. All radios in the 900 MHz and 2.4 GHz bands must use a form of spread spectrum if transmitting over a certain output power. If interference does occur, a good protocol can be used to retransmit or recover the data later on. Using a good protocol has allowed Digi radios to be used where reliable data transmissions becomes critical, such as medical, control and safety monitoring applications.
