How does interference management play into RF optimization?
In order to ensure that a wireless signal is received clearly, interference management must be employed to minimize or eliminate sources of interference. This is especially important in the case of RF optimization, where a small change in signal strength can have a significant impact on performance. By reducing interference, an RF optimization engineer can improve the quality of the signal and ensure that it is received as intended.
