除非您远离任何邻居，否则您可能有多个相互重叠的 Wi-Fi网络。(Wi-Fi)在可能有数十个不同路由器Wi-Fi网络相互交互的公寓大楼中尤其如此。使用Wi-Fi(Wi-Fi)分析仪执行无线站点勘测有助于避免来自其他接入点的干扰，并帮助您设置最佳 Wi-Fi 网络(optimum Wi-Fi network)。
缺点是这些无线网络调查往往很昂贵——除非你自己做。NetSpot 应用程序是(NetSpot App)Wi-Fi网络调查、Wi-Fi分析和无线网络故障排除(troubleshooting of wireless networks)的众多推荐专业应用程序之一。在这篇评论中，我们将提供有关 NetSpot 的Wi-Fi分析仪应用程序的反馈。
什么是 NetSpot Wi-Fi 分析仪？(What Is the NetSpot Wi-Fi Analyzer?)
NetSpot是一款专业级的Wi-Fi分析仪，适用于 iPhone、Android、macOS 和Windows。您可以使用它来执行Wi-Fi网络调查，测量诸如Wi-Fi信道信号强度和整个家庭的干扰等内容。该应用程序包含强大的工具和功能。
NetSpot 功能(NetSpot Features)
当您第一次打开NetSpot时，您会看到范围内每个路由器Wi-Fi网络的列表以及有关这些网络的所有相关信息：SSID、BSSID、频道、频段、安全类型、供应商、模式、信号强度等.
在此默认发现(Discover)选项卡中，NetSpot以设定的时间间隔实时执行扫描。默认情况下，这些实时扫描每十秒发生一次，但您可以将此间隔更改为一整分钟。
调查选项卡是您用来执行无线站点调查的工具。(Survey)
Wi-Fi分析器主屏幕甚至可以让您看到隐藏的路由器网络，尽管它们的名称显示为“隐藏的 SSID。(Hidden SSID.)” 您可以按频道选择和添加网络，(networks by channel)以便更轻松地对选项进行排序。
NetSpot可帮助您测量您的 Wi-Fi 通道信号强度以及您可以采取哪些步骤来改善整个房屋的网络质量和功能。例如，如果您发现某些设备无法正常连接，则使用NetSpot等 Wi-Fi 分析仪进行现场调查可以缩小盲区。
使用调查工具(Using the Survey Tool)
NetSpot中最强大的工具是调查(Survey)工具。您可以使用它来管理现有调查或开始新调查。它为区域提供多种区域类型，包括封闭式办公空间、公寓、立方体农场、户外空间等。
选择正确的区域类型至关重要，因为应用程序使用这些设置来进一步校准其检测算法。
您可以通过绘制空间地图、选择示例地图或从完全空白的地图开始来设计空间地图。您还可以上传办公室或公寓的平面图（如果有的话）并进行处理。
您可以通过选择两个点并输入它们之间的实际距离来校准地图。该应用程序可以进行任意两次测量，并根据这些距离校准平面图的其余部分，前提是您使用的平面图是可缩放的。
此后，NetSpot会询问您是否希望它扫描任何其他 Wi-Fi 网络(other Wi-Fi networks)。完成基本校准后，调查开始。在移动到下一个点之前 ，您可以在地图中选择您的计算机作为Wi-Fi分析仪扫描的第一个点的点。(Wi-Fi)
在地图上选择一个点后，扫描将开始。在扫描期间，您不应将设备从该位置移动。您需要在家中至少三个点重复此过程。
网络分析仪勘测完成后，您可以看到每个区域的详细信息，包括信号强度、信噪比、带宽频率覆盖范围等。选择一个点会显示该点范围内每个网络和Wi-Fi信道的故障。(Wi-Fi)
使用发现工具(Using the Discover Tool)
NetSpot Wi-Fi分析仪应用程序的另一半是Discover工具。此工具显示有关 Wi-Fi 网络的更多详细信息。通过选择一个网络，然后选择应用程序左下角 的详细信息图标，您可以查看其信道、信号强度、噪声级别和安全类型。(Details )
您还可以通过四个不同的选项卡分解此信息：信号(Signal)和噪声(Noise)、表格数据(Tabular Data)、通道 2.4 (Channels 2.4) GHz和通道 5 (Channels 5) GHz。
为什么这很重要？
每个网络范围都有不同的频段。(different bands)例如，2.4GHz 网络有 11 个不同的频段，但其中只有三个不重叠。5GHz 频段具有更多不重叠的带宽，从而产生更好的连接强度和质量。如果您正在寻求最佳的 Wi-Fi 网络质量，那么您可能希望连接到 5GHz 频段。
发现工具(Discover Tool)可让您查看各个带宽以获取有关网络活动的详细信息。使用此故障排除工具来确定要连接的干扰最小的最佳通道。
NetSpot Wi-Fi 分析仪值得吗？(Is the NetSpot Wi-Fi Analyzer Worth It?)

NetSpot App Review – Professional WiFi Analyzer, Tester, and Troubleshooter
Unless you live far away from any neighbors, you likelу have multiple Wi-Fi networks overlapрing one another. This is eѕpecіally true in apartment сomplexes wherе there may be dozens of different router Wi-Fi networks interacting with each other. Performing a wireless sitе survey with a Wi-Fi analyzer can help avoid interference from other access points and help you sеt up an optimum Wi-Fi network.
The downside is that these wireless network surveys tend to be expensive — unless you do it yourself. The NetSpot App is one of the many recommended professional applications for Wi-Fi network surveys, Wi-Fi analysis, and troubleshooting of wireless networks. In this review, we’ll provide feedback on NetSpot’s Wi-Fi analyzer application.
What Is the NetSpot Wi-Fi Analyzer?
NetSpot is a professional-grade Wi-Fi analyzer that works on iPhone, Android, macOS, and Windows. You can use it to perform Wi-Fi network surveys that measure things like Wi-Fi channel signal strength and interference throughout your home. The application is packed with powerful tools and features.
NetSpot Features
When you first open NetSpot, you’re met with a list of every router Wi-Fi network within range and all relevant information regarding those networks: SSID, BSSID, channel, band, security type, vendor, mode, signal strength, and more.
In this default Discover tab, NetSpot performs scans in real-time at set intervals. These real-time scans happen every ten seconds by default, but you can change this interval up to one full minute.
The Survey tab is the tool you would use to perform a wireless site survey.
The main Wi-Fi analyzer screen even lets you see hidden router networks, although their names are displayed as “Hidden SSID.” You can select and add networks by channel to more easily sort through the options.
NetSpot helps you measure your Wi-Fi channel signal strength and steps you can take to improve network quality and functionality throughout the house. For example, if you find certain devices don’t connect as well as they should, a site survey with a Wi-Fi analyzer like NetSpot can narrow down dead zones.
Using the Survey Tool
The most potent tool in NetSpot is the Survey tool. You can use this to manage existing surveys or start new ones. It offers multiple area types for zones, including closed office spaces, apartments, cube farms, outdoor spaces, and more.
Selecting the correct type of zone is essential, as the app uses these settings to calibrate its detection algorithm further.
You can design a map of your space by drawing it, choosing a sample map, or starting with a completely blank map. You can also upload a floorplan of your office or apartment (if one is available) and work off that.
You can calibrate your map by selecting two points and entering the actual distance between them. The app can take any two measurements and calibrate the rest of the floorplan based on those distances, provided the floorplan you use is to scale.
After this, NetSpot asks if you want it to scan any other Wi-Fi networks. After you’ve performed basic calibration, the survey begins. You choose the point in the map where your computer is the first point for the Wi-Fi analyzer scan before moving to the next point.
After you choose one point on the map, the scan will commence. You shouldn’t move your device from this position during the duration of the scan. You’ll need to repeat this process for at least three points throughout the home.
When the network analyzer survey is complete, you can see detailed information about each area, including signal strength, the signal-to-noise ratio, the bandwidth frequency coverage, and more. Selecting a point shows a breakdown of every network and Wi-Fi channel within range of that point.
Using the Discover Tool
The other half of the NetSpot Wi-Fi analyzer app is the Discover tool. This tool displays more detailed information about a Wi-Fi network. By selecting a network and then choosing the Details icon on the lower-left section of the app, you can view its channel, signal strength, noise level, and security type.
You can also break this information down through four different tabs: Signal & Noise, Tabular Data, Channels 2.4 GHz, and Channels 5 GHz.
Why does this matter?
There are different bands to each network range. For example, the 2.4GHz network has 11 different bands, but only three of these do not overlap. The 5GHz band has more bandwidths that don’t overlap, resulting in better connection strength and quality. If you’re seeking the best Wi-Fi network quality, then you’d want to connect to the 5GHz band if possible.
The Discover Tool lets you view individual bandwidths for detailed information about activity on the network. Use this troubleshooting tool to determine the best channel with the least interference to connect to.
Is the NetSpot Wi-Fi Analyzer Worth It?
NetSpot includes many powerful diagnostics tools, and it does so in a lightweight package. There is a free version, but you’ll have access to more of what makes NetSpot useful if you opt for the Home version. It allows you to set up two zones, with two snapshots and 50 data points per zone. You can receive lifetime upgrades for just $19 on top of the base $50 price.
The Pro version is the better bet for commercial use. It’s set up for 50 zones, 50 snapshots, and 500 data points per zone. You can create more than 12 visualizations, as well as gain access to one free technician license if you need to speak with someone regarding your network. You can receive lifetime upgrades for $49 extra.
After spending several weeks with NetSpot, we find that it’s definitely worth the cost for the network performance gains you’ll see. Be warned, though: NetSpot isn’t beginner-friendly. To use the information, you should have at least a base level of networking knowledge.
The good news is that NetSpot includes a user guide with dozens of articles about network terminology and how to use the NetSpot network analyzer to perform a wireless network site survey within your own home to optimize your Wi-Fi network and coverage.
Even with tutorials, it can take time to acquaint yourself with all of the features. NetSpot is powerful, but it can be complicated to use. For example, uploading floor plans didn’t always work as intended, although we had calibrated the app to match the correct distances.
If you have a question or want to submit feedback, you can do so directly within the NetSpot app. The Ask a Question option at the top of the screen lets you reach out directly to the team, and they’ll respond to you through email.
If you have the knowledge and experience with wireless network troubleshooting and diagnostics, you can’t go wrong with NetSpot. But if you’re trying to improve the Wi-Fi within your home and you have no background in networking, you’ll have to do a bit of online reading before you can fully make use of this app.
