What Are Wifi Finders?
With the increased WiFi technology progresses comes and increased wifi coverage in all the countries of the world. There are so many wireless devices that can be connected with each other that this technology is practically offering us a whole new networking perspective, that includes absolute mobility of connection. You could be practically walking the street holding a small laptop and still get constant internet access, with the help of various hot spots that are aiming to offer total coverage, especially in big metropolis.
But if you want to find for example a bench to sit on in a city park and then turn on your laptop and verify the mail you will first need to know if there are any available wireless networks in the area that allow client access freely. This can be done by finding some coverage areas from home, before leaving or by keeping the laptop or mobile device turned on all the time and scanning. Still, neither of the possibilities sounds promising. This is where the Wifi finders or Wifi detectors come in handy.
The wifi finders are small devices that work independently are their only purpose is to find and identify wireless network in the vicinity. They are used to detect wireless networks from the 802.11 protocols, and the detection is done instantly without needing to turn on the computer or the laptop. These devices usually present some type of light signals made of small led lights, that indicate the signals strength in the area. In open spaces, the wifi finders will detect wireless networks that operate no more than 60 meters away, which is a perfect opportunity of detecting networks you will actually be able to connect to if you turned on the laptop.
Using a wifi finder is as simple as it gets. All you need to do is press a button to activate it, and from here on the devices does its job. In case you are worried about other wireless signals that might be confounded with a wireless networks, know that the detectors do not present a signal when they encounter radio frequencies or frequencies that are used by mobile phone or cordless phones and microwave ovens.
A wifi finder is usually something as small as a lighter, that can be worn as a trendy keychain accessory. Because they need portability and because they work without a computer connection, these devices use batteries to function. For a person that like to spent a lot of time relaxing outside but still remains dependent to a laptop that need internet access for various reasons (work, emails, chat), a small device that can detect wireless networks in the near area is an absolute must have.
