How Does Direct Sequence Spread Spectrum (DSSS) Differ from Frequency Hopping Spread Spectrum (FHSS)?
operating under FCC spread spectrum ISM band regulations tolerate interference from neighboring radios and interference from sources other than radios, making them less prone to signal loss. Here's why: The radio spectrum is divided into frequency bands, with each band divided into frequency channels...
