Android Wi-Fi Apps

Ekahau Site Survey Mobile

Use this app with your Ekahau Site Survey Pro software. It can provide a perspective from the client side.

ESS Add-on for Android

Metageek InSSIDer Office

Apparently, I cannot find this in the Google Play store. I know I’ve used it before but it is not there unless I am having a hard time seeing it. What do you guys think?

Airo

This is a Wi-Fi app for Android developed by Aruba Networks. It displays the network health in an easy to read format. The health is split into two areas, Wi-Fi and WAN.

WiFi Analyzer

This Wi-Fi app gives you information about the Wi-Fi networks around you. Displays in a graph of which channels are being used by which networks. It’s a tool you can use to determine which channels you can use for your network.

Fing

This app provides many tools inside it. Fing can be used as a network scanner to detect what is on your network. There’s a Wi-Fi scanner, a tool to detect what’s on your network, port scanner, ping sweep, and more.

CTS 052: How To Validate Wi-Fi Infrastructure

In this episode, I talk with Francois Verges of Semfio Networks about how to validate the Wi-Fi infrastructure.

Validating a Wi-Fi network involves many steps. This is not isolated to a new deployment but also to an existing Wi-Fi network. Francois and I talk about what to validate, look out for, and what resources are available to assist on the job.

Validate Physical Installation

  • Walk through the facility
  • Validate
    • AP installation
    • Antenna orientation
    • With the customer
    • Telco room location

Post Deployment Survey

  • Use your survey laptop and try to use a business critical business device as well (VoIP phone, handheld scanner…)
  • Connect to the infrastructure. Use the most business critical SSID.
  • Use Ping or iPerf to test connection, roaming, throughput.
  • Things to look at while performing the exit survey:
    • What band is the survey laptop using?
    • What band is the client device using?
    • Am I roaming as expected
    • RSSI of both your laptop survey and the client device
    • If you use ESS, you can also connect 1 or 2 dBx antenna to perform a parallel spectrum analysis. (Detect noise and major interferences)

Things to look at after the survey:

  • Coverage
  • Channel distribution / Channel re-use
    • See if some Tx Power need to be adjusted
    • See if some radios need to be disabled (2.4GHz)
    • See if more 5GHz channels are needed
    • Making sure that all the configured channels are being used.

Spectrum Analysis

  • Study both bands: 2.4GHz is usually where you will find the most external interferences
  • Stay still at one location. If you see something unusual, move around to pin point the exact location of the source. (might not be easy). – Plan for a little extra time.

Packet Capture

  • Get a better idea of the RF environment (using Eye P.A.). Thing to look at:
    • Retry rates
    • Channel airtime utilization
    • Data rates
    • How the neighbours can be affecting some channels
  • Being able to see more advanced radio configurations such as:
    • data rates
    • AP capabilities
    • Client capabilities (Big one)
    • Being to spot unusual behaviours
    • Being able to troubleshoot some client issues

Analyze Client Behavior and Configuration

  • Make sure all the client devices of the same model have the same Wi-Fi NIC drivers
  • Make sure all the client devices of the same model have the same Wi-Fi configurations
  • Make sure they manage to connect to the Wi-Fi network (Check delays, does it take a long time to connect?)

Perform Functional Validation Testing

  • Grab a client device, roam around the facility (especially where the device will be used)
  • Validate how the client roams
  • Validate on what band the client connect to
  • Try to ping the application server and see if you lose any pings (make sure it does not affect production)
  • Validate voice quality if it’s VoIP
  • Validate throughput if the requirements need it (try to use the same applications as the one what will be used on the Wi-Fi)

CTS 019: WiFi Predictive Modeling

In This Episode

The first episode for 2016 is going to be about Wi-Fi predictive modeling – how I plan my wireless networks.

But before we get into the meat of the episode, I’d like to share my new year resolutions:

  • CWAP
  • CWDP
  • More learning
  • More podcasts!

Man, I have a lot to work on. What are your resolutions?

My 2016 predications:

  • LTE over Wi-Fi*I meant to say LTE-U and LAA* to gain traction
  • We’ll be working with more poor Wi-Fi
  • Someone will be fined over blocking Wi-Fi
  • Wi-Fi calling will take off

Predictive Modeling

Predictive modeling is a method in which a software application is used to predict the number of access points required on a floor plan based on user inputted capacity and coverage requirements.

As the phrase says, it is a PREDICTIVE model. A wireless installation should be verified to end user requirements.

My application of choice is Ekahau Site Survey.

Some things to consider in your predictive model using Ekahau:

  • Setting Capacity and Performance requirements
  • Setting Coverage requirements
  • Importing a floor plan
  • Setting scale and alignment points
  • Adding a coverage area
  • Adding access points
  • Optimize placement
Configure your network requirements.
