You should use channel numbers 1 or 11 in case of 20MHz channel width. When planning a 2.4GHz WLAN in this area, you should avoid using channel 6.
Now let’s take a look at this frequency: 2405MHz to 2475MHz.Īs you can see in the screenshot above, the frequency range between 2425MHz and 2450MHz has peak energy (noise) reaching levels as high as -23dBm. However, you should check the regulatory information for your country. Note: Usually, frequencies between 5180MHz and 5320MHz, 5745MHz and 5825MHz are allowed for unlicensed use. In reality, this band isn't very crowded the information on this chart simply means you could use any of these frequencies (respecting any restrictions set by your local authority). The key parameter in the Waterfall chart is the power (dBm) across the frequency spectrum in the Waveform chart, the key is the relation between Power Level and number of hits.įor better understanding, see this screenshot of airView in bands 4.9GHz to 6.4GHz:Īs you can see in the first chart (Waterfall), there is a zone between the 5400MHz and 5500MHz that appears to be more crowded, with a signal strength approximately between -84 and -70dBm. In general, for basic analysis, the more commonly used graphs are the Waterfall and Waveform charts. What graphs are analyzed will vary from scenario to scenario and will also depend on the personal preference of each user. Wait for at least 5 minutes for the data gathering before continuing with the analysis.ħ.
On the other hand, if you are using a NanoBridge M5 or NanoStation M2, then airView will only gather data from zone that the antenna can "hear"-the beam width of the antenna. For example, if you are using a Bullet M2HP with an Omni-directional antenna, then airView will gather and show energy levels from all directions. Allow airView to gather sufficient information from the radio spectrum (the beam to be analyzed depends on the type of antenna the device has. Note: You cannot run airView remotely on a wirelessly-connected radio, since the program will terminate the device’s wireless connections.ĥ. Inside airView, you will see three charts which are explained in more detail in the airView Graphs section below.Ħ. Furthermore, it may take up to 30 seconds to switch to the previous wireless mode once airView is closed. Unlike with AC & later devices, M-series devices do not have a dedicated airView chipset, and therefore must use the same data radio to analyze the spectrum. It is not recommended to run airView on airMAX M-series Access Points with connected Stations, since any all connections will be dropped as long as airView is active. If you do not see this window, make sure you have pop-ups enabled on the browser and try again. To agree, press the Launch airView button. 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. Click the Tools dropdown menu and select airView.ģ. Do so by entering the device's IP address in the browser bar. To access the airView utility, log in to the device in question.
