Planning and Deployment Considerations
Prior to deploying an outdoor wireless network, the environment must be evaluated to plan for a successful Aruba WLAN
deployment. Successfully evaluating the environment enables the proper selection of Aruba APs and antennas and assists in
the determination of their placement for optimal RF coverage. This process is considered WLAN or RF planning and Aruba’s
system engineers can assist in the outdoor planning process.

Scale Requirements
The potentially immense scale of outdoor deployments requires consideration of factors that may not be as important in a
typical indoor deployment:
typical indoor deployment:
z
Range (distance): Range or distance between APs must be taken into account during the planning phase. Available AP
mounting locations are often far less flexible in an outdoor environment. Regardless of these outdoor restrictions, the
desired goal is to achieve results similar to an indoor deployment: a “dense” RF deployment that supports advanced
Aruba features, such as ARM, efficient client roaming, and failover.

Elevation: Proper consideration and planning for elevation differences between APs (AP to AP) and AP to Client can be

to success. To plan for these differences in elevation, it is important to understand the 3D coverage pattern
provided by the antennas that will be deployed in the environment.
z
Non-Fixed Considerations: The RF environment might change on a day to day basis. Keep non-fixed items, such as
shipping containers, vehicles, and future building construction, in mind when planning for an outdoor deployment.

Identifying Known RF Absorbers/Reflectors/Interferences Sources
Identifying known RF absorbers/reflectors/interference sources while out in the field during the installation phase is critical.
Even though outdoor environments consist of fewer RF absorbers/reflectors/interference sources compared to indoor
environments, ensure that these sources are identified and taken into consideration when installing and mounting an AP to
its fixed outdoor location.
