What should be considered for selecting WLAN client devices?

Selecting WLAN client devices requires an understanding of their capabilities, particularly in terms of how they interact with the network infrastructure. One key aspect to consider is VHT (Very High Throughput) PHY support in the 5GHz frequency band. This technology is part of the 802.11ac standard, which offers higher data rates, increased capacity, and improved performance when compared to older technologies. Devices that support VHT in the 5GHz band can take advantage of the wider channels and less interference commonly associated with this frequency, leading to enhanced wireless performance and user experience.

Prioritizing VHT PHY support ensures that the network can handle modern applications and higher data throughput demands. Additionally, operating in the 5GHz range helps alleviate congestion that is often seen in the 2.4GHz band, thus providing a more stable and efficient connection for users.

Considering compatibility with older devices, focusing on 2.4GHz support, or network latency contributions may not yield the performance benefits necessary for a contemporary wireless environment, especially given the increasing demand for bandwidth and reliability in WLANs.
