airView Spectrum Analyzer: A Built-in Tool for airMAX M Products


Airview Spectrum Analyzer Download: A Guide for Wireless Network Optimization




If you are looking for a powerful and easy-to-use tool to optimize your wireless network performance, you might want to check out Airview Spectrum Analyzer. This tool is integrated on all Ubiquiti Networks airMAX M products, and it provides a comprehensive spectrum analysis functionality that can help you find the best channel configuration for your wireless network. In this article, we will explain what Airview Spectrum Analyzer is, how to download and install it, how to use it to find the best channel, what are the benefits of using it, and what are some alternatives to it.


What is Airview Spectrum Analyzer?




Airview Spectrum Analyzer is a built-in utility that allows you to conduct a site survey or spectrum analysis at the installation site of your wireless equipment. It can help you identify and avoid noise sources, interference, and other factors that can affect your wireless network performance. Some of the features of Airview Spectrum Analyzer are:




airview spectrum analyzer download




  • It can scan the entire 2.4 GHz or 5 GHz band, or a user-defined frequency range.



  • It can display real-time or average power levels versus frequency in different graphs and views.



  • It can show the occupied bandwidth, center frequency, peak power, average power, and noise floor of each signal.



  • It can filter out unwanted signals based on user-defined criteria.



  • It can export the scan results as a CSV file for further analysis.



Airview Spectrum Analyzer works by using the same data radio that your device uses to communicate with other devices. This means that when you launch Airview Spectrum Analyzer, all wireless connections will be terminated for as long as the program runs. Therefore, it is not recommended to run Airview Spectrum Analyzer on airMAX M-series Access Points with connected Stations, as this will disrupt their service. Also, you cannot run Airview Spectrum Analyzer remotely on a wirelessly-connected radio, as this will terminate its connection as well.


How to Download and Install Airview Spectrum Analyzer?




To use Airview Spectrum Analyzer, you need to have a Ubiquiti M-series device running airOS v5.2 or higher. You also need to have Java VM version 6 or higher installed on your PC or laptop that you will use to access the device. Here are the steps for downloading and installing Airview Spectrum Analyzer:



  • Connect your PC or laptop to the device using an Ethernet cable.



  • Open a web browser and enter the device's IP address in the address bar. By default, the IP address is 192.168.1.20.



  • Log in to the device using your username and password.



  • Click the Tools dropdown menu and select airView.



  • A pop-up window will appear, with a warning that states that by launching airView, all wireless connections will be terminated for as long as the program runs. To agree, press the Launch airView button.



  • A file named airview.jnlp will be downloaded to your PC or laptop. Open and run this file.



  • Airview Spectrum Analyzer will - Airview Spectrum Analyzer will launch and start scanning the frequency band that your device is configured to use. You can change the frequency range, the scan duration, and the scan resolution from the Settings menu.



How to Use Airview Spectrum Analyzer to Find the Best Channel?




Once Airview Spectrum Analyzer is running, you can use it to find the best channel for your wireless network. Here are some tips on how to use the tool effectively:



  • Choose the appropriate graph or view for your analysis. Airview Spectrum Analyzer offers four types of graphs and views: Waterfall, Waveform, Realtime, and Average. Each one has its own advantages and disadvantages, depending on what you want to see and measure.



  • Waterfall shows the power levels versus frequency over time, with different colors representing different power levels. It is useful for identifying trends, patterns, and changes in the spectrum over time.



  • Waveform shows the power levels versus frequency at a specific point in time. It is useful for measuring the peak power, average power, noise floor, and occupied bandwidth of each signal.



  • Realtime shows the power levels versus frequency in real time, with a moving line that updates every second. It is useful for detecting transient or intermittent signals that may not show up in other graphs or views.



  • Average shows the average power levels versus frequency over a user-defined period of time. It is useful for smoothing out noise and fluctuations and showing the overall spectrum usage.



  • Use the zoom and pan functions to focus on a specific frequency range or signal. You can zoom in or out by using the mouse wheel or the + and - buttons on the toolbar. You can pan by clicking and dragging on the graph or view.



  • Use the filter function to exclude unwanted signals from your analysis. You can filter out signals based on their frequency range, peak power, average power, or noise floor. You can also invert the filter to show only the signals that match your criteria.



  • Use the cursor function to measure specific values on the graph or view. You can move the cursor by clicking on the graph or view or using the arrow keys on your keyboard. You can see the frequency, power level, and bandwidth of the signal at the cursor position on the status bar.



  • Use the export function to save your scan results as a CSV file for further analysis. You can export all or part of your scan results by selecting the Export menu and choosing either Export All or Export Selection.



  • To find the best channel for your wireless network, you need to look for a frequency range that has low noise floor, low interference, and high available bandwidth. You can use any of the graphs or views to do this, but we recommend using the Average view for a general overview and then switching to the Waveform view for more details.



  • In general, you want to choose a channel that has a high signal-to-noise ratio (SNR), which is the difference between your signal's peak power and the noise floor. A higher SNR means a better signal quality and a lower chance of errors and retransmissions. A good rule of thumb is to aim for an SNR of at least 20 dB.



  • You also want to choose a channel that has low interference from other signals, especially those that have similar frequencies or overlap with your channel. Interference can cause degradation of your signal quality and reduce your throughput. A good rule of thumb is to avoid channels that have signals with peak power higher than -80 dBm or average power higher than -90 dBm.



  • You also want to choose a channel that has high available bandwidth, which is the difference between your signal's occupied bandwidth and the total bandwidth of your channel. A higher available bandwidth means more room for data transmission and a higher throughput. A good rule of thumb is to aim for an available bandwidth of at least 80% of your channel bandwidth.



What are the Benefits of Using Airview Spectrum Analyzer?




Using Airview Spectrum Analyzer can help you optimize your wireless network performance in many ways. Some of the benefits of using this tool are:



  • You can find and avoid sources of noise and interference that can degrade your signal quality and reduce your throughput.



  • You can choose the best channel configuration for your wireless network based on objective data and measurements.



  • You can monitor and troubleshoot your wireless network performance over time and identify any changes or issues that may arise.



  • You can save time and money by avoiding trial-and-error methods or expensive equipment for spectrum analysis.
