Turns your android phone into a Wi-Fi analyzer!! Shows the Wi-Fi channels around you. Helps you to find a less crowded channel for your wireless router. Also avoid getting your phone near powerful electrical devices like power transformers since you might damage it.

Use at your own Spectrum Analyze gives you real-time spectrum data from the microphone on your Android device. Uninstall the app, and re-install. Perform any pending system update sand re-install the app. Turn the internet on, before you start Frequency counter based on the microphone input. Counts when the input rises or falls past a set level and converts into into frequency or a time period.

Results depend on your device and its hardware.

If you just want to We will keep the simple user interface for the next versions! There will be no overwhelming and confusing menus or features you don't even know what to do! Possible applications of BlueScan; -There are various research Do you This app is for RF and microwave students, engineers and hobbyists.

App has many RF calculators and resources that will help you in study and in professional life. We have several useful calculators here: TeeThere are two ways to make a broadcast receiver known to the system: One is declare it in the manifest file with this element. The other is to create the receiver dynamically in code and register it with the Context.

For more information about how to dynamically create receivers, see the BroadcastReceiver class description. Warning: Limit how many broadcast receivers you set in your app.

Having too many broadcast receivers can affect your app's performance and the battery life of users' devices.

For more information about APIs you can use instead of the BroadcastReceiver class for scheduling background work, see Background Optimizations. Whether or not the broadcast receiver is direct-boot aware ; that is, whether or not it can run before the user unlocks the device. Note: During Direct Boota broadcast receiver in your application can only access the data that is stored in device protected storage.

If either is " false ", it is disabled; it cannot be instantiated.

The default value depends on whether the broadcast receiver contains intent filters. The absence of any filters means that it can be invoked only by Intent objects that specify its exact class name. This implies that the receiver is intended only for application-internal use since others would not normally know the class name. So in this case, the default value is " false ". On the other hand, the presence of at least one filter implies that the broadcast receiver is intended to receive intents broadcast by the system or other applications, so the default value is " true ".

This attribute is not the only way to limit a broadcast receiver's external exposure. You can also use a permission to limit the external entities that can send it messages see the permission attribute. The label should be set as a reference to a string resource, so that it can be localized like other strings in the user interface. However, as a convenience while you're developing the application, it can also be set as a raw string.

For more information on permissions, see the Permissions section in the introduction and a separate document, Security and Permissions. If the name assigned to this attribute begins with a colon ':'a new process, private to the application, is created when it's needed and the broadcast receiver runs in that process. If the process name begins with a lowercase character, the receiver will run in a global process of that name, provided that it has permission to do so.

This allows components in different applications to share a process, reducing resource usage. Content and code samples on this page are subject to the licenses described in the Content License.

These must be read at an extremely close range, typically a few centimeters. You can get some decent readers from a lot of manufacturers by simply searching on google.

There are a lot of plug in ones for all device types. I use SerialIO badge readers that I load a decryption profile onto that allows our secure company cards to be read and utilized by an application I built. They are great for large scale reliable bluetooth scanning. The only problem is, HID readers are very expensive and are meant for enterprise use. The tag manufacturer should have an SDK for you to use to connect to and manage the tags.

First is understanding that RFID is very generic term. NFC is used for prox card, credit cards, tap and go payment system. NFC is very short distance and low power - which is why you see tap and go type usage. The more common RFID are the tags you see here and there. They come in a wide ranges of styles, uses and frequency. HF - high frequency tags are what they use for "chipping" animals - cattle, dogs, cats.

Read range is about 12 inches and requires an external antenna that is powered the bigger the antenna the more power it needs and the further it can read. Mutiread means when a reader is active, you can litterally read about tags in under 10 seconds.

But this is a function of the size of the antenna and how much power you can push through the reader.Overview Specs. You can browse through the frequency spectrum just by using scroll and zoom touch gestures. This app is in active development and I'm currently working on the following features:- Optimizing the signal processing to lower CPU usage and increase filter performance- Bookmarks- Scanner scan a specific range for the strongest signal I also try to keep the app stable and as bug-free as possible.

Bugreports are always welcome and I promise to work hard to resolve every one of them. Note that there is a loggingfeature in the settings which helps a lot with trouble shooting any errors. Also notice that doing the necessary digital signal processing is very CPU intensive and though I did my best to optimize the algorithms the app still needs a decent device I recommend 2 CPU cores or more to run fluently. Please use the 2-hour refund period provided for every Google Play app to test functionality and refund the app if it does not work for your device.

The APK package is also available in thegit repository and you can download and install it from there. But keep in mind: by buying the app you will get automaticupdates and you will support my work.
