Outdoor 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
routers 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.

planning process.
For WLAN systems being installed outdoors in the USA, the following requirements must be met.
1. Systems must be professionally installed by a qualified engineer familiar with WLAN, including Aruba
trained partners and resellers.
2. Operation in the 5600-5650-MHz band is prohibited.
3. When within 35 km distance of a TDWR, the center frequency of the WLAN must be separated from the
TDWR center frequency by 30 MHz.
a. If the radar is operating from 5600-5610 MHz, disable the use of channel 116 (5580 MHz).
b. If the radar is operating from 5630-5650 MHz, disable the use of channel 132 (5660 MHz).

Scale Requirements
The potentially immense scale of outdoor deployments requires consideration of factors that may not be as
important in a typical indoor deployment:
important in a typical indoor deployment:
Range (distance): Range or distance between routers must be taken into account during the planning
phase. Available 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, efficient client roaming, and failover.

Elevation: Proper consideration and planning for elevation differences between routers (router to
router) and router to Client can be critical 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.

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