Introduction to Line of Site (LOS) / Non Line of Site (NLOS) channel emulation

Getting meaningful and repeatable throughput results using a turntable.

How OFDM & OFDMA work and specific challenges of OFDMA

Using a multi-probe sniffer for OFDMA, roaming and other system tests.

Fundamentals of RF link budget

An overview of the Broadband Forum TR-398 standard for testing Wi-Fi performance.

The fundamentals of antenna physics and the methodology of achieving optimum MIMO and MU-MIMO performance in a wireless testbed

This session welooked at the similarities and differences between testing in a testbed vs in a test house and reviewed industry recommendations on the topic as well as looked at current state of the art practices

This tutorial reviews the IETF RFC 2544 that is sometimes recommended for testing Wi-Fi routers

This tutorial examines the origins of Mesh Wi-Fi technology as well as its evolution to date, including the mechanics of how mesh works and the types of technology variants currently deployed

In this tutorial we continued our analysis of mesh Wi-Fi. We looked at various mesh topologies and the impact of an increasing amount of wireless hops to the throughput as well as the latency of a connection. We also drilled into the steering algorithms implemented in mesh products and some of the current challenges that we see in the market.

This tutorial discusses Target Wake Time (TWT) and how it enables devices to determine when and how frequently they wake up to send or receive data. This allows devices to increase sleep time thus reducing power consumption. TWT can also be used to reduce overlap and contention between stations resulting in optimized spectral efficiency.

We demonstrate how the octoBox testbed can be used to test various TWT parameters and will show the impact to traffic scheduling and throughput.
