The 3 Stages Approach to Evaluating an AP

Join the 7SIGNAL team along with special guests Firas Shaari from Comcast. In this webinar, Firas discusses the advanced 3 stage testing approach to evaluating new AP’s for Comcast. Come see how they separate the wheat from the chaff at one of the largest telecom companies in the US.
Key takeaways:
Understand how to set up and execute all 3 stages of testing which include conductive, over-the-air (OTA) and test house
Using testing to understand performance at levels 1 and 2
Setting up Access Point testing in different test environments
How to analyze information received from testing your new Access Point

Power Management in Client Devices

During this episode, Mike discusses power management mechanisms in Wi-Fi, starting with legacy Wi-Fi and covering additions in each subsequent standard.
Key Takeaways:
PS-Poll Mode and TIM and DTIM elements
WMM and Automatic Power Save Delivery (APSD)
Power Savings with MIMO
VHT TXOP PS
And more!

Ultra-High Density Wi-Fi

In this episode, join special guest Arjan Kievits in a discussion about high-density Wi-Fi. During the session, Arjan will talk about the emerging demand from higher education organizations to design a network that can properly handle large groups of students during online exams. 
Key takeaways: Learn about the requirements, physical challenges, testing results, and [re]designs needed to have a high-performing Wi-Fi network.

Wi-Fi Jamming Discussed

In this webinar, join Lee Badman as he leads the discussion on Wi-Fi jamming. We will discuss what Wi-Fi jamming is, what it looks like, and why it occurs. 
Some key takeaways:
What is jamming in relation to Wi-Fi?
Why would anyone jam Wi-Fi?
What laws exist related to jamming?
How can jamming be used in WLAN attacks?
How can we detect jamming?

Best Practices for Mounting Outdoor APs

During this episode, join 7SIGNAL's Jack Clifford as we discuss all things outdoor Access Points. During the session, Jack will talk through best practices so you can avoid sub-optimal performance. 
What we'll cover:
Design challenges unique to outdoor wireless
When to use point-to-point and point-to-multipoint network
Common outdoor Wi-Fi issues and how to avoid them
Installation requirements of outdoor APs

Best Practices for Supporting Wi-Fi Clients

You did your site surveys, you did a redesign, you checked for code bugs, and yet your end-users still complain about the Wi-Fi. What’s wrong?
In this episode, Jim Vajda, Chief Wireless Officer and CWNE #183, will teach us why Wi-Fi clients are just as important as access points in determining Wi-Fi performance, and they must be addressed for the network to meet its full potential.
Some topics we’ll cover:
General client best practices
What to do about BYOD
Recommendations for Windows, macOS, iOS, and Android clients
Getting client-level visibility with 7SIGNAL Mobile Eye
And more!

How CCA-SD Works on Secondary Channels

Building on Jim Vajda's episode on wide channel contention, guest host Gjermund Raaen will get into the nuts and bolts of how an 802.11 STA actually performs signal detection in its secondary channels.
Takeaways:
How a receiving station synchronizes to a receiving frame
What happens if a station does not see the preamble
Why does a station not use CCA-PD on secondary channels

The Evolution of WLAN Rogues

The threat of rogues has changed. While some things have improved, such as general awareness and improved security protocols, rogues are still causing issues and finding ways to infiltrate devices. In this session, we discuss the evolution of WLAN rogues. Join Lee Badman, CWNE #200 and Jim Vajda, CWNE #183, as we discuss this topic and much more.
Topics we'll cover:
An overview of rogues and the motive behind them
The evolution of rogues and what they look like in the modern world
Whether rogues are still problematic and what to do when you find them

Just How Fragmented Is the Wi-Fi Client Space?

Today’s WLAN systems promise fantastic speeds and performance, but they have a major strike against them - the endpoints. In this session we’ll look at several real-world Wi-Fi environments to see what various mixes of client types and vintages are in play, and discuss the implications of what it means when the client half of the industry doesn’t keep up with the infrastructure side. Join Lee Badman, CWNE #200, and Jim Vajda, CWNE #183, as we discuss this topic and much more.
Topics we'll cover:
Infrastructure vs endpoints
Wi-Fi standards
Real-world WLAN problem environments 

Wide Channel Contention

How does Wi-Fi contention work when the channel width is greater than 20 MHz? We encounter AP’s operating with wide channels all the time, so it’s important to know what contention looks like on those channels. Jim Vajda, CWNE #183, will introduce you to all the differences in channel access across the PHY’s and across different channel widths. 
Topics we'll cover:
Everyday 20 MHz EDCA
802.11n 40 MHz channel access
802.11ac 40/80/160 MHz channel access
802.11ax 40/80/160 MHz channel access
Implications for design
