The WiSE Article Series: Wi-Fi Subtleties Explained (Parameters that Matter)

In this second article in the Wi-Fi Subtleties Explained (WiSE) series, Bhaskaran Raman talks about parameters that impact Wi-Fi throughput. You may be surprised to learn that it's not all about the lower layers (Physical and Data Link), but the TCP communications have a significant impact as well.

Dynamic Rate Switching (DRS) and Performance - WLAN Foundations

An intentional part of the 802.11 standard is Dynamic Rate Switching (DRS). DRS adjusts the data rate in order to reduce retransmissions. If the data rate remains at a high rate when the client is farther from the AP, it will result in so many retransmissions that the actual throughput is greatly reduced. Continue reading...

I'm Thankful for the 802.11 Protocol

Today, I was thinking about the 802.11 protocol (no surprise there) and how it relates to Thanksgiving. I realized that Thanksgiving is a time when many of us who celebrate it reflect on the year behind us and appreciate the good things and maybe even some of the bad things that turned out better than we expected. So I began to think about all the good things we have because of the 802.11 protocol. Continue reading...

Tablet-Based Site Surveys with AirMapper

Both AirMagnet and Ekahau provide a tablet-based product for performing site surveys. By focusing on AirMapper in this blog post, I can narrow my comments, but I am not suggesting that it is a superior product to Ekahau’s tool. However, AirMapper is less expensive (in the Pro edition) and also comes in a limited feature free version available through the company website at flukenetworks.com.

Wireless Field Day 3 - Juniper Networks

Juniper Networks claims to have the best performing AP in the industry. Whether that is true or not depends on real-world results and independent analysis; however, they do offer controller-based WLANs that redirect data transmissions directly to the LAN and not through the controller. This can provide improvements in performance in certain scenarios with congested LANs and may provide improved performance as WLANs are more heavily used. Continue reading...

Wireless Field Day 3 - Cisco Mobility

Cisco addressed the topics of Hotspot 2.0 (HS 2.0), 802.11ac, Bonjour and AVC in their presentation at Wireless Field Day 3 (WFD3). Everyone knows what Cisco does, so I'll address some of their comments without more introductory remarks. Continue reading...
