Android Candy: WiFi Analyzer

I have a new day job, and as part of the hiring package, I was issued a smartphone. I'm a little bitter that it doesn't include a tethering plan, but that doesn't upset me nearly as much as the lack of Wi-Fi analysis apps. See, my new job issued me an iPhone. I really like the iPhone (it's true, I can't lie), but in order to scan Wi-Fi, I'd have to jailbreak my phone!

Thankfully, the world of Android has no such silly limitation. If you've ever wanted to scan for access points or check signal levels in different parts of your house, WiFi Analyzer is an excellent (and free!) tool. WiFi Analyzer will show currently available access points, graph signal strength as you walk around the house, and even give information on signal quality.

Screenshot from the Google Play Store

I've used WiFi Analyzer to determine the best placement of access points when deploying a building-wide wireless infrastructure. I've used it to pick the best channel for my home access points. I've even walked down the road with it to see what my neighbors use as SSIDs. (That last one might be a little creepy, but really, if people name their wireless networks after Teletubbies, you want to keep an eye on them.)

Because it's incredibly useful, completely free and not available on iOS, WiFi Analyzer gets this month's Editors' Choice award. Check it out at http://a.farproc.com/wifi-analyzer.

In my business as a headshot photographer, I need to find access points constantly. If you've ever wanted to scan for access points or check signal levels in different parts of your house, WiFi Analyzer is an excellent tool.

Increase the signal

Anonymous's picture

It would be an interesting test to see if you can increase the signal with a tin can or empty pringles cup. (If the phone fits in there) I know it works with a smaller wifi adapter but I am not sure about a cell phone.

Apple Vs Android phones

This issue of apple restricting their smartphone's capabilities is one thing I have never understood. All in all, no matter what features I would like to unlock on an iphone, i would not dare jailbreak it due to its cost and I would not risk my investment. Breville bov800xl

Detective / Private Investigator usage of WiFi Analyzer

ΝΤΕΤΕΚΤΙΒ's picture

As a professional detective / private investigator I am using android WiFi Analyzer to check for available access points and measure graph signal strength as I perform my investigations all around the town of Athens and get information on signal quality of the Access Points that I use to connect to the Internet.

Please check my Web Site www.erevna.gr or www.insider.com.gr for further information.

If you need further information on how you can use the WiFi Analyzer for Spy purposes please contact my private investigations office.

Anonymous's picture

There is also WiFiFoFum, which has an actual radar layout. Uses Wifi and GPS. It's available on Google Play (https://play.google.com/store/apps/details?id=com.dynamicallyloaded.wifi...), and on the Cydia (from BigBoss), and just about every other mobile OS out there. I haven't tried taking the ipa and adding that to iTunes, and then adding that to my iPhone, but that usually works anyways.

Fantastic App

Michael Knisely's picture

I've used this tool to find APs stuck up in drop ceilings, forgotten under desks, and even one jammed in the floor joists in one building.

I use it for basic coverage testing too; it has pretty much replaced my use of Chanalyser, a software I payed a pretty penny to have. I find the form factor of my tablets and phones to be much more preferential to even a Slate 500 for doing this type of testing.

I wholeheartedly agree with this pick!

This is true

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
