A wireless adapter is a category of connectivity devices that work with PCs or PDAs, smartphones, and the like. In PCMCIA (card) form, the wireless adapter enables a laptop to join a Wi-Fi network. Other form factors consist of conventional PCI add-in cards that connect directly with a PC motherboard and USB sticks that plug into an external USB port.

The typical wireless adapter tends to be small, no matter the precise form factor. In fact, many notebooks and netbooks now provide built-in wi-fi networking, with small chips inside providing the capabilities of a wireless network adapter.

And some models these days can even function as wi-fi print servers that permit one or two printers to be conveniently shared across a network. This offers for several important benefits, starting with not having to deal with wires. Also, a computer isn’t required to manage all the jobs within the printing queue, and it does not necessarily need to be turned on in order to print, even.

Wireless adapters are also increasingly popular as a result of multiplayer gaming, and it’s easy to see why! There’s nothing like inviting a bunch of friends over for a LAN party – without all of the wires. And many of today’s portable gaming consoles come with wireless capabilities right out of the box, with absolutely nothing more to buy and install or even configure.

Wi-fi network adapters are also being utilized for video conferencing. As broadband becomes more and more the performance standard, audio-visual applications are expected to skyrocket. Prospective buyers can view real estate in real-time without having to travel for a site visit.

Firms can monitor the security of sensitive places on their premises, with instantaneous e-mail and text message alerts when motion sensors detect any activity. The possibilities are enormous when signals are freed from the confines of wires and require relatively little infrastructure to support them!
