l802.11n Hotspot Deployment wit hin an Existing Environment—This t ype of environmentrequires that
AP/AM locations be fixed at the building level, see "Fix All SuggestedA P/AMs" on page 813. If you set and fix
the location of APs prior to planning for the 802.11n APs, the APs will not move when you initialize/optimiz e
the 802.11n AP locatio ns.
l802.11n Hotspot Deployment an d New Environment—The RF Plan allows you to plan for a new deployment
that uses an 802.11n hotspot and 802.11a and/or 802.11 b/g support outside of the hot spot.
To plan for this type of deployment, start by planning your 802.11n hotspot. When you initialize and optimiz e
the APs plannedfor the hotspot ,t he8 02.11n APs are placed within the hotspot area. However, the sameA P
type will also be placed outside of the hotspot area with 802 .11n support disabled.
RF Plan will deployA Ps outside of the hotspot area based on the 802.11a and/or 802.11b/g rates defined by the
system. For the system to define 802.11a and/or 802.11b/g rates, the system looks at the defined 802.11n rate
and thedi stance coveredby t hedefined rate; it then selects corresponding 802.11a and/or 802.11b/g rates based
on the distance covered.
Planning Deploym ent
Dell recommendsthe following when planning and deploying a mesh solution:

Pre-Deploym ent Consideratio ns

lStage the APs before deployment.Identify the locati on of theA Ps, configurethem for mesh, provision them and
verify connectivity before physically deploying the mesh APs in a live network.
lEnsuret he controllerhas Layer-2/3 network connectivity t o the network segment whereyou plan to i nstallthe
mesh portal.
lKeep the AP packaging materials andreuse them to send the APs to the installation location.
lVerify the layout of the physical location to determine the appropriate configurationand placement of the APs.
Use this information to avoid problems that would necessitate a physical recovery.
lLabelt heA P befores endingit t o the physical location for installation.

Outdoor-Sp ecific Deploym ent Consideratio ns

lProvision the AP with the latitude and longitude coordinates of the installation location. This allows you to
more easily identify the AP for inventory and troubleshooting purposes.
lIdentify a “radio line of sight” between the antennas for optimum performance. Theradio line of sight involves
the areaalong a link through which the bulko ft heradio si gnalpower travels.
lIdentify the minimum antenna height requiredto ensure a reliable mesh link.
lScan yourproposed site to avoid radio interference caused by otherradio transmissio nsusing the same or an
adjacent frequency.
lConsider extremeweather conditi ons known to affect your location, including: temperature,wi nd velocity,
lightning,rain, snow, and ice.
lAllow for seasonal variations, such as growth of foliage.

that came with your outdoor AP.

Configura tion Considerations

lOndual-radio APs, you can configure onlyo neof the radio for mesh. If you wanta dual-radio AP to carry mesh
backhaultraffic and client services traffic on separate radios,D ellrecommends using 802.11a radios for mesh-
backhaultraffic and 802.11g radios for traditional WLAN access.
