Wireless devices are becoming more and more popular. For some, a wireless connection network problem can be a costly and annoying experience. Identifying the presence of a wireless device can be crucial for business or personal communication. A WiFi sniffer is an interesting new tool that will help you find a signal when you need it the most.
Hotels and airports allow access to networks for business and leisure travelers, and networks are often useable to people who may work or study from a park bench, a coffee house, or a shopping center. Mobile WiFi antennas give truck drivers, RV vacationers, and other mobile individuals continual access to the Internet, so they don’t need to keep their laptops or PDAs at home, and can always stay connected to their families or their employers.
As though such gadgets weren’t enough, WiFi enthusiasts can now purchase a sniffer, which is a wireless tool that locates the presence of other wireless devices, measures the strength of their signals, and provides a report to the owner on the location of the access point.
A WiFi sniffer can be a valuable tool for campers, backpackers, and other outdoor lovers. Should you ever become lost while hiking or traveling in remote areas, by 'sniffing' the location of other wireless devices, it could enable you to call for help, or find your way back to your camp or destination.
Similarly, if you were to misplace your own wireless equipment, such as your notebook, bluetooth or PDA, your sniffer could assist you to find it; or if you're having a wireless connection network problem and are in critical need of a connection, your sniffer would send you a report of other such devices close by.
These are all satisfactory uses for a WiFi sniffer, but network accessories such as these can also be used for more sinister intents. For instance, a hacker intent on sabotaging or corrupting the users of any WiFi network could use his or her WiFi sniffer to detect the presence of wireless devices, set up a fictitious WiFi network, or hack into the existing network, and steal personal information from the users.
As well, the owner of a cyber café intent on stealing customers from a competing café could utilize their sniffer to study the network traffic of their competitor, and then elect to lower the price of accessing their network to lure customers away from their competition. Or, the managers of a shopping mall may use their device to count the number of people who connect to their network, and then raise the cost to increase more profit from their customers.
Like many tools, a WiFi sniffer can be used for good or evil, and it is contingent upon the objectives for which someone uses it. But if you are suffering with a wireless connection network problem, being able to access another nearby network can be a lifesaver. If you are interested in purchasing a WiFi sniffer, be sure to do a complete internet search on the range of products on the market. Get information on mounting your device, and chat with current owners to find out what other accessories you may need.
