Wireless Field Day 7 was a whirlwind of activities: new WLAN technologies, presentations, driving, vendors, coffee, food, new relationships, more driving, more coffee, more food, WLAN tech-filled evenings with delegates and vendors, and then you return to the hotel room and crash each night with your mind “on fire”, pouring over all the tech stuff of the day! Oh, and did I forget to mention: this was one of the greatest experiences in my Wi-Fi career!
So here begins my first of three blogs: Impressions of WFD7. Disclaimer #1: The vendors/presenters did give each of the delegates branded merchandise, sample products, memorabilia, meals and beverages. A hearty “Thank You” to each vendor who provided these items from this grateful delegate! Fluke Networks David Coffin, Fluke CTO, welcomed us to the “world headquarters of wireless measurement”. Wireless Nerd. HD3 Removal – Feci-Fi. Ah, HD3.
The laughing stock of Twitter a couple years back after Devin Akin did his extensive post of how much of a failure it is. ( I had the pleasure of hanging out with Devin on the first week of my employment at my former workplace and it was during one of these days that a colleague and I took Devin over to our new hospital to show him this monstrosity of a design. The pictures in his post are from that location. In case you haven’t clicked on that link yet, let me explain what HD3 (High Density, Design, Demand?) Here is my colleague trying to draw it on a whiteboard… So in the simplest terms possible, HD3 is 3 wireless systems that are installed over top of each other.
This all sounds so wonderful! But unfortunately, then the clients see this: (emphasis added) To quote the sales guy during a meeting: “When the network has no clients, the system is flawless!” Wireless VOIP phones (iPhones) were constantly dropping in all areas of the hospital. The best and most comprehensive Wi-Fi Blogroll on the web! Blog — 802dotMe. It seems like I could begin every blog post by referring to the growing demand for ubiquitous access to Wi-Fi, and every day there seems to be less hesitation to ask for wireless access everywhere a few people might gather.
At times, wireless professionals are tasked with deploying a network in a temporary location for conferences, large public meetings, outdoor festivals, etc., and very few good solutions to properly securing and orienting an access point have existed until now. Based on some hands-on time with the this product, that changes with the introduction of the Wi-Fi Stand by Frontera Consulting.
What Exactly Is It? Wi-Fi Stand is actually not a full, adjustable height stand. Rather, it's all the "hard parts" about temporarily mounting an AP assembled into an easy to store and deploy solution that you can attach to the style and size of stand of your choosing. Blog – Great White WiFi. I recently had an encounter at my day job that left me staggered.
There was a network outage at one of our locations. Our WAN is a VLAN leased from a wireless ISP, or WISP. We had some power outages over the weekend in the area, so when the network was down on Monday morning, […] read more. Ben's Wireless journey. Rob Krumm – ROBROBSTATION. Nowadays when you speak with a WLAN professional you will often hear the suggestion of setting or restricting minimum PHY rates to optimise your WLAN’s performance.
Many professionals nowadays consider this to be one of the basic tasks that must be completed in the process of configuring and optimising a WLAN. Configuring the minimum rates in a WLAN can have many benefits to your network’s performance including reduction of management overhead, removal of unnecessary RTS/CTS frames, better airtime utilisation, and enhanced throughput in the Extended Service Set. It is an especially useful tool in High Density scenarios like big convention halls, sports stadiums, large lecture theatres and any other environment with many clients in a relatively small space. Personally I set the minimum rates on all HD designs especially in the 2.4Ghz band! (Yes, I have used 2.4Ghz in High Density deployments.
Learn the basics of Enterprise Wi-Fi networking in this podcast series. Wifi Nigel. WLANs, WiFi & Technical musings. My name is Nick Turner I have had a wide and wandering career path to date, ranging from Theatre Stage Technician, Film crew, Silviculture industry including reforestation (I have worked as a Tree Planter) in British Columbia, mountain pine beetle surveying in Alberta and forest fire fighting in BC.
During my last year spent in Canada I worked for a WISP in the North of BC, where I would go to work on a quad bike or a snowmobile depending on the season, climbing communication towers surrounded by beautiful British Columbia wilderness, primarily dealing with point to point and point to multipoint radio links. It was there that the radio communications ball began rolling, along with the CWNP certification program. More recently I have been working in the UK specialising in WLAN design and gradually working towards becoming a Wireless Networking Professional. @nickjvturner. I ♥ WiFi. The WiFi knowledge base. Using concept maps to become a CWAP (Part 1) Last year I became a Certified Wireless Network Administrator (CWNA), and doing so showed me that I really didn't know about wireless networks as well as I thought, even though I work with them everyday.
It is true that my every day interactions with wireless networks are very different from those of a typical WLAN engineer. I don't do surveys, I don't install AP or WLAN controllers, I don't even design networks! My involvement with wireless networks at the moment includes research, development and testing of transport and routing protocols for tactical mobile ad-hoc networks (MANETs), and some cyber-security work on moving target defenses (MTDs). Many of you also know me as the author of a few Wi-Fi tools for Mac, being the most popular WiFi Explorer. I started WiFi Explorer back in 2012 and thanks to the feedback of the WLAN community, especially a very large group on Twitter, the tool has matured quite a bit. Wattiswifi. Devin Akin - Divergent Dynamic's Wireless. Simply because it’s awesome, I thought I would write a blog about the AirCheck G2.
It’s my favorite WiFi diagnostics tool, hands-down. It does so many things in such a small, rugged form factor that it’s impossible not to love. I thought I would jot down a few thoughts on market trends. 2×2:2 Client Devices The market is trending toward 2×2:2 clients. PotatoFi Blog □ Top 10 Wi-Fi Issues. In Wi-Fi network environments, users face many challenges with their experience.
Workers are increasingly mobile and want to bring their own devices (BYOD). The sheer quantity of wireless devices on the network is stretching the boundaries of the original design intent. Analyse de couverture Wi-Fi et de sécurité. A signal strength map, or SNR map, is quite similar to a Wi-Fi coverage map (heatmap), but this type includes Wi-Fi signal to noise ratio when graphically displayed.

Real World Examples of Device RSSI Comparison. Wireless clients are without question one of the leading problematic components of a wireless network. Many WiFi engineers agree 80% of issues on todays WiFi networks are client related. Wireless clients are much like humans. They all speak, hear, and act a bit differently from one NIC/Driver to another. While you might observe similar or identical behavior across a specific device type, but a simple driver update can change everything you know about how that device behaves.
In this blog post I will share 5 devices in two real world scenarios specific to how devices interrupt signal (RSSI). ★ learn stuff! — Wi-Fi Republic. Wi-Fi: the unobvious and overlooked details – part 1. Everyone nowadays buys ‘super-fast’ 802.11n or 802.11ac APs, but not everyone manages to get super-fast connection with them. In this article we’ll discuss the not-so-obvious or often overlooked nuances that can substantially improve (or impair) the Wi-Fi connection.
Everything below is applicable both to small home networks with off-the-shelf consumer-grade routers using stock and advanced (DD-WRT, etc) firmware, as well as to enterprise-grade gear and networks. Thus, to keep it simple, I will be using the home WLAN as an example, since even the most advanced admins and most proficient engineers still live in residential areas with high neighbour AP density, and everyone wants fast and reliable Wi-Fi. Before we begin, a few comments: The narrative is a little simplified, as you might want to explain some of these aspects to your neighbours, who probably have no clue of RF essentials, 802.11 standard or government regulatory policies.Everything below is a recommendation only. . [1.2]. WiFi Kiwi's Blog. 30 Random Technical Thoughts by a WiFi Engineer - Airheads. 1) CRC is cyclic redundancy check. This means a radio received a frame and failed the checksum. A normal communication the intended receiver will not ACK and the sender will retransmit the frame.
What’s important to understand when sniffing just because you have a high CRC rate in your sniffer window doesn't mean the actual client communication is experiencing the same. In fact while sniffing, if you experience a high CRC rate moving closer to the transmitting radios often solves the problem. It simply means your radio can't interpret the frame. 2) When a client on channel transmits a frame ALL radios on the channel must synchronize to the preamble and demodulate the pending frame. 3) Noise calculations done by an 802.11 radio knows nothing about layer 1 spectrum.
Daleswifisec. A sticky problem – Wi-Fi clients that won’t roam. By WildDev on May 22nd, 2013 I work in a very interesting industry. It seems like in no time, WLANs have gone from being a nice to have but definitely optional thing to something that everyone must have in order to operate their businesses. Part of the issue with this rapid change is that we are left with some decisions made in the past that have turned out not so great in the present day.
