Security - Here you will find the type of security that is protecting the network. ![]() The band field indicates which frequency is in use by a given network. The channel is determined by your WiFi router’s configuration.īand - WiFi networks broadcast radio waves in either the 2.4 GHz or 5 GHz frequencies. You may see SSIDs that are hidden, meaning that the only way to access the network is to already know its name.īSSID - The Basic Service Set Identifier (BSSID) identifies the MAC address of the access point.Īlias - If the network has an alias it will appear in this field.Ĭhannel - This field shows the channel that the WiFi network is using for data transmission. This field will indicate which network you are currently connected to and provide the names of all wireless networks that are in range. SSID - The Service Set Identifier (SSID) is simply the name of the network. Let’s take a look at what these bits of information can tell you about your network. There is a wealth of information that a WiFi scanner can provide you concerning your and surrounding networks. What Information Can A Wireless Scanner Provide? It’s even better to use your Android device as your WiFi scanner. Therefore, it is better to install wireless scanning software on a laptop than a desktop computer. As we will see later in the article, the ability to scan your network from various locations in your coverage area is critical in optimizing your network. The utility of a WiFi scanner is tied in part to its size. You can install WiFi channel scanning software on your desktop or laptop computer as well as on smartphones and tablets. Today you can still find these devices but there are a number of other options available to you. In the not too distant past, the best way to scan WiFi networks was with a dedicated, self-contained, handheld device. They are an indispensable tool when planning, installing, and maintaining a WiFi network. If you’re still using an old single-band router, then spending around $100 on a solid dual-band router is a purchase you won’t regret.īy following these three simply WiFi channel planning best practices, you should be able to achieve the best download and upload speeds possible and avoid issues with latency, signal interference, and coverage.Identify nearby wireless networks and supply details of various network characteristicsĪ WiFi channel scanner is a tool that is designed to enable the user to identify nearby wireless networks and supply details of various network characteristics and statistics. Use a dual-channel WiFi router: Modern routers are capable of broadcasting simultaneously on the 2.4 GHz and 5 GHz bands.It’s sometimes better to use a channel that’s utilized by three other networks that are very far away than one network that’s very close. Consider the strength of each found network: The number of networks using a WiFi channel isn’t the only factor that matters.Analyze WiFi channels at different times of the day: Some WiFi networks, such as those created by printers and wireless security cameras are active only during certain times of the day, so it pays off to analyze WiFi channels more than once.Here are some basic WiFi channel planning best practices to help you achieve this goal: When using NetSpot to find the best WiFi channel, you need to keep in mind that your ultimate goal is to avoid co-channel interference, which occurs when two or more WiFi routers operate on the same channel or neighboring channels. With noise, you want to get as far away from zero as possible, so -90 is better than -80. For example, an RSSI of -50 is better than an RSSI of -60. RSSI is indicated in negative numbers, and the closer it is to zero the better because zero means that no signal strength has been lost during transmission. Noise indicates how much interference caused by other signals affects the particular connection. The former stands for “Received Signal Strength Indicator,” and indicates how well a WiFi-enabled device can receive signals from a WiFi router. To determine which non-overlapping WiFi channel is the best, you need to consider Step 1: Understanding RSSI and Noise Values In such situations, your best option is to use a WiFi channel scanner or analyzer and find the least crowded non-overlapping channel. ![]() In public spaces, apartment buildings, offices, and other densely populated areas, it’s very common for multiple WiFi routers to broadcast simultaneously on a single non-overlapping channel.
