• Recommendations:

○ Enterprises should perform site surveys selectively (e.g., to understand signal propagation in noisy

locations) rather than throughout the enterprise.

○ Enterprises should avoid trying to maintain a model of their design once it is deployed because they will

quickly reach a point of diminishing returns.

○ Enterprises should require that vendors document their network-design plan and BOM. In addition,

enterprises should require that vendors pay for any extra wiring and APs that are not itemized in the

original BOM.

○ Enterprises should consider management products that enable a network administrator to hierarchically

navigate among many sites as well as provide the ability to navigate through simple lists of devices.

○ Features such as auto-power assignment, auto-channel assignment, and guest-access security are baseline

requirements for all vendors.

○ Enterprises should carefully test vendor features such as load balancing, band steering, beamforming,

ATF, and service–level-assurance (SLA) mechanisms.

○ Small and medium-sized enterprises should consider cloud-based network management systems that offer

deployments based on software as a service (SaaS).

○ Enterprises should consider vendors that provide the ability to capture AP and client statistics over time

and to easily “re-play” those statistics.

○ Enterprises should consider vendors that provide the ability to not only collect historical information, but

also correlate client statistics with client location over time.

○ Enterprises should consider vendors that integrate spectrum analysis and classification with real-time

network control into their products.

Conclusion:

The fundamental enterprise challenge to deploy a robust, reliable WLAN is the ability to control the

underlying RF signals. As enterprises pervasively deploy WLANs, the challenge of controlling the RF signals

results in greater complexity for the network-design, network-management, and problem-diagnosis activities.

Aruba, Cisco, Meru, and Motorola provide the most comprehensive set of capabilities to address the design,

management, and diagnosis use cases defined in this assessment.
