Can IEEE 802.15.4 coexist with other radio systems?
Yes, the IEEE 802.15.4 standard has been specifically designed to coexist with other radio systems operating in the ISM bands, and to provide robust transmission in the presence of interference. The IEEE 802.15.4 standard defines interference avoidance protocols ('Energy Detect', 'Link Quality Indication' and 'Clear Channel Assessment') and also implements direct sequence spread spectrum modulation. This reduces the power spectral density and lowers the required signal to noise ratio, improving interference immunity.
