What is the primary purpose of dual-band access points in Aruba?

The primary purpose of dual-band access points in Aruba is to increase capacity and performance by utilizing both the 2.4 GHz and 5 GHz frequency bands. This dual-band capability allows for more efficient management of bandwidth, as the 2.4 GHz band offers wider coverage and better penetration through obstacles, while the 5 GHz band supports higher data rates and less interference due to its additional channels.

By operating on both bands simultaneously, dual-band access points can accommodate a larger number of devices and distribute network traffic more effectively, leading to improved overall performance. This is especially important in environments where many users are connected to the network, as it helps to alleviate congestion and ensures a more reliable experience for all devices.

This combination optimizes network efficiency and enhances user experience, which is critical in today's advanced wireless environments where multiple devices are simultaneously accessing the network. The other choices, while relevant to various network functionalities, do not directly address the fundamental role of dual-band access points in enhancing network capacity and performance through the use of multiple frequency bands.
