SNR
Another important metric to consider when building a wireless network is the signal to noise
ratio (SNR). With 11n networks, an SNR of 28dB or greater is often recommended, particularly
if voice and/or video applications are present. Although this recommendation still applies for
11n clients running on 11ac networks, for 11ac clients to achieve their highest possible data
rates, the SNR should be greater than 32dB. For 11ax clients an SNR of -35dBm is recom-
mended.
Switch and PoE Guidelines
In this section, we will provide recommendations for switching and PoE capabilities.
FAP-U43xF
The recommendation is to boot up the AP on the 2.5G port to gain the 11ax data rates.
Controller
As mentioned previously, if the data plane is configured for tunneled mode, a 10G uplink from
the controller to the connecting switch is recommended, as all data plane traffic will need to
pass through the controller's Ethernet port/s. A 10G uplink can be used for bridged mode
deployments as well, but since all data plane traffic avoids passing through the controller's
Ethernet port/s, a 1G controller uplink port will most often be more than adequate for bridged
mode deployments.
PoE
FAP-U43xF requires approximately 25W (802.3at) static power supply. Customers that cur-
rently have 802.3af power will need to upgrade to 802.3at power. If the FAP-U detects an
802.3af power source, the radios will be disabled. The LAN1 and LAN2 ports are for uplink.
It is recommended to enable LLDP on the switch.
