For a voice only application, data rates higher than 24 Mbps can optionally be enabled or disabled, but there is no advantage
from a capacity or throughput perspective and enabling these rates could potentially increase the number of retries for a data
frame.
Other applications such as video may be able to benefit from having these higher data rates enabled.
To preserve high capacity and throughput, data rates of 24 Mbps and higher should be enabled.
If deploying in an environment where excessive retries may be a concern, then a limited set of the data rates can be used (e.g.
12, 24, 54, MCS 1, MCS 4, MCS 7), where the lowest enabled rate is the mandatory / basic rate.
For rugged environments or deployments requiring maximum range, it is recommended to enable 6 Mbps as a mandatory /
basic rate.
Note: Some environments may require that a lower data rate be enabled due to use of legacy clients, environmental factors or
maximum range is required.
Set only the lowest data rate enabled as the single mandatory / basic rate. Multicast packets will be sent at the highest
mandatory / basic data rate enabled.
Note that capacity and throughput are reduced when lower rates are enabled.

Rugged Environments
When deploying the Cisco IP Phone 8861 and 8865 in a rugged environment (e.g. manufacturing, warehouse, retail), additional
tuning on top of the standard design recommendations may be necessary.
Below are the key items to focus on when deploying a wireless LAN in a rugged environment.

Below are the key items to focus on when deploying a wireless LAN in a rugged environment.
Access Point and Antenna Selection
For rugged environments, it is recommended to select an access point platform that requires external antennas (e.g.
Cisco 1602e, 2602e, 3502e, 3602e, and 3702e Series Access Points). It is also important to ensure an antenna type is
selected which can operate well in rugged environments.

Access Point Placement
It is crucial that line of sight to the access point’s antennas is maximized by minimizing any obstructions between the
Cisco IP Phone 8861 or 8865 and the access point. Ensure that the access point and/or antennas are not mounted
behind any obstruction or on or near a metal or glass surface.
