Why Do I Want a Wireless Adapter?

 

Answer

 

Wireless networking has added a degree of flexibility and connectivity for both business and personal use that was, until recently, unthinkable. The technology allows for fast and easy setup of a relatively simple network in the home or one that is widespread throughout a business. Further, it does it all without the expensive and inconvenient infrastructure associated with a wired network. Use of USB  wireless adapters also allows for making internet connections at an ever-growing number of public locations like cafés and hotels. They also allow for direct ad hoc connections between Wi-Fi enabled devices without the inclusion of infrastructure devices like a router.

 

There are a number of prevalent wireless technologies that affect just about all of our daily lives. Most ubiquitous are the cell phone networks. Bluetooth, a short-range technology that pairs wireless devices to one another, is also common. But when it comes to wireless networking, the specific technology involved is Wi-Fi. The wireless adapters featured in this review site are vital components of Wi-Fi connectivity.

 

It’s true that most newer laptop computers generally come with Wi-Fi built in. Even with such computers, the role for wireless adapters is widespread. Many laptops have older versions of Wi-Fi and therefore can’t take advantage of the tremendous improvements that are contained in the current standard. Additionally, the integrated Wi-Fi is typically single band which limits its ability to stream high definition, bandwidth-intensive content. The older standards are also much more susceptible to interference from other electronic devices.

 

Wireless adapters can be ideal for desktop computers which rarely have Wi-Fi built in. It’s a far simpler matter to plug in a USB Wi-Fi adapter than it is to run an Ethernet cable to a computer, especially when multiple machines are involved.

 

Though they’re rather simple devices, there are distinct differences and advantages between wireless adapters. Our reviews will help you choose the best one for your particular needs.
