WN Blog 016 – WiFi Tools

Hey!

I am putting this blog together to cover some of the wireless tools that we use or are highly recommended in the wireless community.

Many of you might already be aware of some of the tools in this blog but there might be some in here that you have not come across before that you could find quite useful.

We will kick things off with the WiFi tool we use the most, which is Ekahau.

Ekahau

If you are a wireless engineer then this is a must-have in your tool bag – we use it for everything – from designing wireless networks to troubleshooting them.

Ekahau is certainly rich in products & features so we will just cover them here quickly:

Wireless Sensors / Packet Capture devices

Kubicon

Kubicon

 

Kubicon system consists of two components- cloud based dashboard and a hardware Wi-Fi sensor which basically mimics end user Wi-Fi  behaviour.

All that needs to be done in order to deploy the solution is to perform configuration on cloud console which is central point of management and reporting and to deploy sensors across desired environment. 

 The solution monitors number of important factors such as Wi-Fi signal quality , bandwidth capacity, network service, web applications, etc. from wireless end user perspective. Additionally it calculates overall Wi-Fi client experience score, based on these values. All metrics are available in real-time on cloud dashboard or on demand in form of reports which in turn can  be exported to multiple easy to read/use formats. Based on the mentioned architecture and  features, we are able to detect current issues and predict possible problems in the future. 

 

 One of the most frequent issues we have experienced in Wi-Fi environments was related to Guest Wi-Fi networks, particularly lack of (proactive) monitoring and analytics of Captive Portals.

 

That’s why we are very proud that we managed to develop comprehensive Wi-Fi captive portal testing and monitoring, with the features such as:

 

  1. Landing page responsiveness
  2. Identification of excessive time taking to load the landing page
  3. Real time Authentication – which helps to identify backend issues during constant client authentication checks

WLAN-Pi

WLAN-Pi

 

“The WLAN Pi project started in 2016 at WLPC. The goal was to create a portable, ready-to-use device that could function as a network endpoint for measuring network performance and throughput.

Since then, it has been widely embraced in the awesome wireless community and after many contributions, this tiny box has evolved well beyond a network performance testing device.

Today, it can also be used as a remote Wi-Fi scanner, packet capture tool, portable Wi-Fi signal generator and much more! These capabilities assist wireless professionals with designing better wireless networks, troubleshooting issues more quickly, and validating wireless network performance.”

Metageek – Wi-Spy

Wi-Spy

 

Powerful Dual-Band Spectrum Analysis

Chanalyzer Essential includes Wi-Spy DBx, a powerful dual-band spectrum analyzer that measures WiFi and non-WiFi activity in both the 2.4 GHz and 5 GHz bands. Chanalyzer utilizes radio frequency data from Wi-Spy DBx to provide you with a real-time visual overview of your WiFi network environment.

Locate Sources of Interference

Once you’re able to see interference, the next step is to eliminate it. Unlike the omnidirectional WiFi antenna in your laptop or wireless adapter, a directional antenna is highly focused to pinpoint non-WiFi sources of interference. This allows you to actively seek out and remove loud transmitters from your WiFi environment.

Monitor Channel Saturation and Intermittent Interferers

By graphing every access point within reach and pairing it with the raw RF information provided by Wi-Spy, Chanalyzer provides you with all the information you need to monitor and manage saturated channels. The built-in recording feature even allows you to track the most frustrating WiFi problem – intermittent interference – and come up with a plan to eliminate it for good.

Aruba utilities

Aruba Utilities

 

Aruba Utilities includes a number of tools useful for characterizing and troubleshooting wireless LANs from Aruba Networks. Some tools work with any WLAN, others are clients for Aruba’s AirWave management system, Analytics & Location Engine (ALE) and Mobility Controllers.

Aruba Utilities includes:

• A Wi-Fi Monitor showing the Wi-Fi environment, including the current access point, dynamic signal strength and RSSI measurements, other access points audible to the device and handover events.

• A Telnet/SSH client that works with Aruba mobility controllers, allowing network configuration and monitoring from a mobile platform.

• An AirWave client that downloads the floorplan image and AP details from the network’s AirWave WLAN management system. See where APs are located relative to your position, and touch AP icons for details of current loading, channels and power.

• The AirWave client also offers a locally-generated estimated heatmap and a site survey function that links actual coverage measurements to locations on the floorplan.

• Device information (Wi-Fi, IP, DHCP, cellular status) is displayed along with an implementation of the Airwave Management Client (AMC) that reports device information and scanned APs to your AirWave WLAN management system.

• A Bluetooth Low Energy (BLE) scanner reports nearby iBeacons and other BLE devices with UUID, index values and signal strength measurements.

• Android versions of iPerf, Ping, DNS and mDNS offer network test functionality.

• Measurements are written to a plain-text log file and various csv report files that can be emailed for use later.

WiFi Manager

WiFiMan

 

WiFi Manager is ideal for analyzing nearby Wi-Fi networks and Bluetooth LE devices, device discovery, and network speedtests. These features are conveniently accessed through the sleekly designed UI created by Ubiquiti Networks. WiFiman contains no ads and is free of charge.

WiFiman helps you locate a less crowded channel for your Wi-Fi Access Point. It lists nearby Wi-Fi channels and Bluetooth LE devices and shows you the details of those channels.

With the app, you can easily list and analyze devices connected to your current network. WiFiman scans the whole network subnet and shows you all of the available devices with the applicable details, using Bonjour, SNMP, NetBIOS, and UBNT discovery protocols.

Another core feature is the network speed test. You can test the speed of your internet connection and save the results for later comparison – or quickly share the results.
