Precision Timing: 5G mmWave (NR) Systems and Noise Consideration

As demand for video, voice and data increases, both at fixed and mobile networks, information “pipelines”must be broadened, and transmission speed must be enhanced. 5G communication networks offer service providers multiple choices to allow increased capacity and speed,such as applied higher speed modulation techniques, and multiple transmission channels at higher frequencies. While modulation speed, added multiple channels, increased bandwidth and transmission frequencies offer advantages when it comes to capacity enhancement, they also introduce challenges when it comes to noise generation and noise tolerance.

In this whitepaper, we will address noise in wire-line systems (re: jitter) and in wireless systems (re: Error Vector Magnitude (EVM), major contributors for increased noise levels, and relationship to signal sources.
