In 2020, following the new IEEE 802.11ax standard, the Wi-Fi Alliance announced Wi-Fi 6. This name was a bit of a misnomer, as the Federal Communications Commission (FCC) in the United States had not yet opened up the 6 GHz frequency band for commercial use, so Wi-Fi 6 devices were still limited to the 2.4 and 5 GHz bands.
Several years ago, we wrote about budgeting for a wireless project. Specifically, we wrote about a common question we get from prospective clients related how to budget for the design, installation, and post installation phases of a wireless project? As a follow up to that post, We are going to answer the question we always get next, which is how much does a WiFi survey cost?
WiFi Optimization Best Practices
Wi-Fi is an ever-present force in all our lives and as time goes on, it only becomes more complex. Deploying and optimizing WiFi is no longer as simple is cranking up the signal power or randomly placing multiple access points in areas of the building.
Three Types of Wireless Site Surveys
There are several types of wireless site surveys. One type is a passive wireless survey, which is conducted by collecting RF signal data while walking around the area. These measurements are then used to generate coverage heatmaps for desired area. Active wireless surveys are conducted by creating wireless network connections to either the installed WiFi network or test/temporary WiFi network and take signal and sometimes other measurements like speed testing and application testing. Predictive wireless survey / modeling is computer based design process that takes into considering the floor plan, wall material, and another other information that may impact wireless signals and generates signal propagation results / coverage heatmaps. Regardless of the type of survey used, the goal is to collect accurate and relevant data that can help design a wireless network that meets the needs of users.
Is Wireless Site Survey Worth It For My Business? How Much Does it cost?
“Measure twice, cut once,” is a famous proverb. Obviously it is a great rule for a carpenter. Cut the wood improperly and the piece is ruined. It’s more cost effective and faster to double-check the requirements before taking action.
Do you have a wireless network that isn't performing well or plan to install a new WiFi network? You most likely need a wireless site survey. A wireless site survey helps to determine where to place WiFi access points to provide proper signal coverage and performance.
The outcome of a wireless site survey is usually a report that details the number of access points needed and the location they should be installed.
It’s important to recognize that a wireless device’s type of 802.11 technology and the number of spatial streams supported are the limiting factors in increasing the MCS index (and therefore the maximum data rate possible). Since this is a hardware limitation, it acts as the ceiling for what is possible.
Many articles have been written on how to properly calculate the quality of a WiFi connection. In this blog we will introduce one concept, the modulation and coding scheme (MCS) index, and show how it can be used to understand the quality of a WiFi connection for Windows and Mac OS computers. Modulation refers to the way data is formatted prior to transmission. The coding scheme refers to how the data is encoded while being transmitted.
Like most things in life, working from home is not always easy. You might have to deal with finishing up a project on a tight deadline, or you might be trying to get some much-needed peace and quiet for said project. But when your WiFi starts acting up and getting too slow for your liking, it can make those "working from home" days feel anything but productive.
The problem with WiFi is that it's ripe for interference when you're working from home. Between neighbors personal devices, cars, appliances, and even your own devices emitting WiFi signals, it can get pretty crowded in the airwaves. And when too many devices are clogging up airwaves shared by your router at once, it's bound to start causing some problems.
Luckily for you (and the rest of us working from home), it doesn't have to be this way. And fortunately for you, AccessAgility is here to help. AccessAgility has been a leading provider of WiFi discovery and analysis software for many years, and we have seen the same issues over and over again.
In this article, we'll go through some of the most common WiFi issues when working from home. We'll also review some best practices to avoid these issues in the first place.
If you are like me, then you love to tinker with hardware. Whether it is a desktop or a mobile device, I am always looking to explore and experiment with new technology. One of the best things about Linux is the ability to use powerful tools free of charge. If you are a Linux user like myself, then you already know that there are many different types of software available for almost any task.
The one area where I have always found Linux to be lacking is a solid WiFi Scanner similar to what is available for Windows, Mac OS, Android and even Apple's iOS. I think the main reason is that the user base on Linux is not large enough for organizations to invest in creating a high end native Linux WiFi scanner.
This is one of the reasons we created a way for users of Linux devices to be able to leverage our Windows WiFi Scanner to remotely connect to Linux devices for WiFi Scanning. We think this is a good compromise between getting scanner data based on how the Linux devices see it versus creating a native Linux WiFi scanner.
Other Linux WiFi Scanner options below based on my research. As you can see the user interfaces are not as high quality as what you find on other operating systems and the features of each app are limited.
LinSSID – A Graphical WiFi Scanner for Linux
LinSSID is a graphical WiFi scanner for Linux, and is available in several flavors. For my needs, I chose the Graphical version:
The LinSSID interface is built using HTML5 and CSS3 technology. The interface looks great, simple to use and opens quickly. Although you can scan as many networks as you like, for this review I'll focus on the Auto-Scan feature that will scan all wireless SSIDs that it can find and then present them to you in a new tab so that you can manually perform any necessary scans. Once your scans are complete, your network information along with the identified devices are saved into text files located in the "/home/$USER/.essid" directory.
HORST - Highly Optimized Radio Scanning Tool
This next option is Horst. It is a free, command-line interface lightweight IEEE 802.11 WLAN analyzer with a text user interface. Horst can be used on any wireless LAN interface which supports monitor mode.
Kismet is another graphical WiFi scanner for Linux. Kismet works similar to the other two tools mentioned here and it also has a chart page, but one additional feature that makes Kismet stand out is that you can compare your scans with another of your choice and add notes to the comparison.
