During an RFP analysis, one of the vendors mentioned that you'll need to upgrade your Gigabit Ethernet switches to MultiGig switches to ensure support for 802.11ac and 802.11ax, which both offer data rates over 1 Gbps. Why is this not sound advice?
A.
Because neither of the technologies support data rates over 1 Gbps
B.
Because 802.11ax doesn't support channel bonding
C.
Management overhead that is normal in WLANs will reduce the throughput of the client devices
While 802.11ac and 802.11ax standards support theoretical data rates exceeding 1 Gbps, real-world throughput is often lower due to various factors, including management overhead, environmental conditions, and client capabilities. The actual data throughput experienced by clients is typically less than the maximum PHY rates due to protocol overhead and other inefficiencies inherent in wireless communication.
The CWDP-305 Official Study and Reference Guide notes:
"Theoretical maximum data rates are seldom achieved in practice due to factors such as protocol overhead, interference, and client limitations. Therefore, infrastructure upgrades should be based on actual performance requirements and measurements."
Therefore, advising an upgrade to MultiGig switches solely based on the theoretical maximum data rates of 802.11ac and 802.11ax may not be justified without considering actual network performance and requirements.
