802.11a and 11n use six (6) “pilot” subcarriers as a reference for the receiver to detect frequency and phase shifts of the signal.

802.11a/g/n OFDM includes several combinations of modulation and coding to achieve data rates from 1-600 Mbps.

With 802.11a OFDM, 16-QAM provides either 48 or 54 Mbps data rates, depending upon coding rates.

802.11ac VHT-OFDM utilizes 256-QAM, which increases the data rate significantly over 64-QAM available in HT-OFDM.

In 802.11a OFDM, fifty-six (56) subcarriers are used as parallel symbol transmission paths to carry data.

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.
