In Aruba networks, what does the term "client density" refer to?

The term "client density" in Aruba networks specifically refers to the number of clients connected to the network within a particular area. This metric is crucial for designing and optimizing wireless networks since high client density can lead to network congestion, performance degradation, and challenges in maintaining adequate service levels for all users. Understanding client density helps network administrators plan for appropriate access point placement, determine bandwidth requirements, and ensure that the overall network architecture can support the expected load.

While the other options mention factors that can impact network performance, they do not define client density itself. Instead, they pertain to other aspects of network management, such as data usage, proximity to access points, and connection speeds.
