如果您正在寻找可以监控您的WiFi网络问题的工具，NetSurveyor就是您的理想之选。NetSurveyor是属于WiFi 扫描器^{(WiFi Scanners)}或 802.11 网络发现工具类别的诊断工具^{(Discovery Tools)}。它实时收集有关附近接入点的信息，并使用各种不同的诊断视图和图表显示数据。

NetSurveyor 软件评论

该工具具有许多功能和应用程序。可以记录数据以供以后回放，并且可以以Adob​​e PDF格式生成报告。NetSurveyor作为免费软件分发，不需要许可证。您可以免费下载并使用它。

NetSurveyor 功能^{(NetSurveyor Features)}

• 软件^(Software)通过简单的 UI 易于理解和使用。
• 在简单的网格视图中反复更新每个接入点的信息。
• 它以 6 个图形诊断视图表示数据：(1)每个接入点的^{(Access Point)}信标^{(Beacon Qualities)}质量的时间进程，(2)每个接入^{(Access Point)}点的信标质量的^{(Beacon Qualities)}差异显示^{(Differential Display)}，(3)每个 802.11 b/g通道的^(Channels)使用情况^(Usage)，( 4)每个 802.11 b/g通道的^(Channels)使用^(Usage)时间过程，(5) 802.11 b/g 通道的Heatmap / Waterfall Chart和 (6) 802.11 b/g通道的^(Channels)通道^(Channels)频谱图^{(Channel Spectrogram)}。
• 它支持多个无线适配器，即那些安装了NDIS 5.x驱动程序（或更高版本）的适配器。它包括在Windows XP^{(Windows XP)}、Vista和Windows 7上运行的无线适配器。
• 报告以Adob​​e PDF格式生成，其中包括接入点列表及其属性以及 6 个诊断图表中每一个的图像。
• 独特^(Unique)而强大的记录和记录功能。
• 其创新方法有助于快速查看记录的数据。

NetSurveyor 的工作原理^{(How NetSurveyor works)}

NetSurveyor是一种发现工具，它报告它检测到的每个无线网络的服务集标识符^{(Service Set Identifier)}( SSID )，以及为该网络提供服务的接入点 (AP) 使用的信道。大约每 100 毫秒，AP 会发送一个“我在这里”信标——该工具会拾取该信标并将SSID添加到其已知无线网络列表中。此外，它还会报告每个 AP 的RSSI（接收信号强度指示^{(Received Signal Strength Indication)}），大致表明 AP 与您当前位置的距离。

NetSurveyor 应用程序^{(NetSurveyor Applications)}

• 对运行缓慢的 Wi-Fi 网络进行分析和故障排除。
• 验证无线网络的正确安装，即网络是否正确配置以及天线是否位于实现高效传输/接收的位置。
• 报告WiFi网络和本地接入点的存在及其信标的信号强度。
• 进行无线站点调查。
• 检测恶意接入点的存在。
• 作为帮助理解接入点 ( BSSID^(BSSIDs) )、无线网络 ( SSID^(SSIDs) ) 和客户端站 ( STA^(STAs) ) 之间关系的指导工具。

NetSurveyor: WiFi Scanner and Network Discovery Tool for PC

If you are looking for a tool that cаn monitor your WiFi netwоrk рroblems, NetSurveyor is the software for you. NetSurveyor is a diagnostic tool that falls under the category of WiFi Scanners or 802.11 Network Discovery Tools. It gathers information about nearby access points in real-time and displays the data using a variety of different diagnostic views and charts.

NetSurveyor software review

The tool has many features and applications. Data can be recorded for later playback and reports can be generated in Adobe PDF format. NetSurveyor is distributed as freeware and does not require a license. You are free to download it and use it.

NetSurveyor Features

• Software is easy to understand and use with a simple UI.
• Repeatedly updates information about each access point in a simple grid view.
• It represents data in 6 graphical, diagnostic views: (1) Timecourse of Beacon Qualities For Each Access Point, (2) Differential Display of Beacon Qualities for Each Access Point, (3) Usage of Each of the 802.11 b/g Channels, (4) Timecourse of the Usage of Each of the 802.11 b/g Channels, (5) Heatmap / Waterfall Chart of the 802.11 b/g Channels and (6) Channel Spectrogram of the 802.11 b/g Channels.
• It supports multiple wireless adapters- that is, those that are installed with an NDIS 5.x driver (or later). It includes wireless adapters running on Windows XP, Vista and Windows 7.
• Reports are generated in Adobe PDF format in which the list of access points and their properties along with images of each of the 6 diagnostic charts are included.
• Unique and powerful logging and recording capability.
• Its innovative approach helps in quickly reviewing recorded data.

How NetSurveyor works

NetSurveyor is a discovery tool that reports the Service Set Identifier (SSID) for each wireless network it detects, along with the channel used by the access point (AP) servicing that network. Approximately every 100 mSec an AP sends an “I’m here” beacon – and this tool picks-up that beacon and adds the SSID to its list of known wireless networks. Also, it reports the RSSI (Received Signal Strength Indication) for each AP, which roughly indicates how close the AP is to your current location.

NetSurveyor Applications

• Analyzing and troubleshooting the Wi-Fi networks that are performing slowly.
• Verification of the proper installation of a wireless network, i.e whether the network is properly configured and antennas are positioned at locations to achieve efficient transmission/reception.
• Reporting the presence of WiFi networks and local access points and the signal strengths of their beacons.
• Conducting wireless site surveys.
• Detecting the presence of rogue access points.
• As a guiding tool to help understand the relationship between access points (BSSIDs), wireless networks (SSIDs), and client stations (STAs).
