The RF interference caused by passing airplanes supporting on-board Wi-Fi should be a prime consideration.

The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible.

The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.

The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey.

Spatial multiplexing

Short guard intervals

Maximal ratio combining

Orthogonal Frequency Division Multiplexing

An IP tunnel is established between the AP and controller for AP management and control functions.

Using centralized data forwarding, APs never tag Ethernet frames with VLAN identifiers or 802.1p CoS.

With 802.1X/EAP security, the AP acts as the supplicant and the controller acts as the authenticator.

Management and data frame types must be processed locally by the AP, while control frame types must be sent to the controller.

In a distributed data forwarding model, the AP handles frame encryption and decryption.

With a spectrum analyzer, identify the type, amplitude, and location of RF interference sources, if any are present.

Evaluate the building materials at ABC’s facility and confirm that the floor plan documents are consistent with the actual building.

Test several antenna types connected to the intended APs for use in the eventual deployment.

Collect information about the company’s security requirements and the current configuration of their RADIUS and user database servers.

Install at least one AP on each side of the exterior walls to test for co-channel interference through these walls.

Alternates between awake and dozing, depending on its need to transmit and receive information

Enters a low-power radio state until it receives a WMM PS-Poll frame from the AP

Experiences higher throughput and lower latency than when operating in Active mode

Powers down a subset of MIMO radio chains and transmits information at a slower data rate

Buffers frames destined to the low-power AP until the AP wakes its radio and begins beaconing again

All vendors use the same protocol so that APs will interoperate with WLAN controllers from other vendors.

Some vendors use proprietary protocols, and some vendors use protocols based on public standards like RFCs.

For most vendors, the controller-based APs maintain data and control tunnels with at least two controllers for immediate failover and redundancy.

All vendors support at least one L2 or L3 broadcast protocol for controller discovery by controller-based APs.

All vendors recommend using L2 (instead of L3) controller discovery and tunneling protocols in large enterprises.

Predictive modeling software can predict the ideal access point location 100% of the time, whereas the results from manual surveying are less reliable.

Predictive modeling software makes it simple to assess multiple different AP locations and then adjust and display the AP’s expected coverage pattern in almost real-time.

Predictive modeling software provides more reliable data than manual surveys when fine-tuning and validating access point placement after the installation.

The exact impact of interference sources from external networks can be more accurately measured when using predictive modeling software than with manual surveys.

It takes less time to create an initial site survey for a large facility when using predictive modeling software than when performing a manual survey.
