What is a WiFi Finder?
A WiFi finder is a small, portable, battery operated device that locates wireless hotspots so you don’t have to turn on your laptop to see if a network is available. The most basic model is about the size of a mouse, though there are also very small keychain models. Most WiFi finders have a single button and three or more LED lights. Depressing the button starts the device searching for WiFi signals. Most finders search in the 802.11b/g bands. If no networks are detected, the LEDs remain off. A weak signal will initiate one light, while the strongest signal initiates all LEDs. If only one light is steady, you can head in a direction that causes more LEDs to light. When lights flash, the signal is intermittent or weak. A more expensive WiFi Finder might have additional capabilities to make things even easier. For example, one available model is built like a small flip phone, where the flipped end acts as a rotating high gain antenna. This makes it easy to hone in on the direction of the
For many people, WiFi wireless connections to the internet have become such an important part of their daily work and personal activities that they become very dependent on such access, to the point where they can feel lost when they don’t have it. When such people, who have developed somewhat of “WiFi dependency” are called upon to be away from their primary access points, they will need to seek out WiFi hotspots to keep their wireless mobile devices linked up to the net. A WiFi Finder is a very handy little device that makes it easier to find hotspots with good signal strength. Devices that are enabled for wireless mobile networking, such as personal digital assistants, PDAs and laptops generally have some type of built-in function that will indicate when there is an WiFi hotspot available to connect to. However, there are some laptops that have to be rebooted in order to get a correct reading of the WiFi network availability, which can be a significant hassle when trying to simply m
The Wi-Fi Finder is a handy little device that is small enough to be carried on your key chain or in your pocket. The Wi-Fi finder can identify wireless signals and allow the use to locate the the strongest signal location. Normally signal strength is displayed by a set of LED lights; the more lights – the stronger the signal.
