60 GHz Statistical Channel Characterization for Wireless Data Centers
This letter presents 60 GHz radio channel measurements and characterization in a productivity data center. Path loss and delay spread are statistically modeled for possible use cases corresponding to potential deployment scenarios in a wireless data center (WDC) Models behaviors are then used to highlight the propagation differences across use cases. It was found that most use cases are characterized by a rich scattering channel and sub free space path loss exponent values. Compared to common indoor environments, delay spread and path loss values suggest a better link budget at higher distances and possibly higher interference in dense deployment scenarios. The reported models and key propagation behaviors are useful for practical system design and evaluation of WDC millimeter wave links.
