One of the little talked about benefits of the latest-gen smartphones and tablets is the fact that manufacturers are finally starting to implement wireless chips inside them that can utilize 802.11n at 5 GHz. Many people don’t realize, but before the iPhone 5 and iPad 3, all of Apple’s smartphones and tablets only leveraged wireless chips that operated at 2.4 GHz. This is a problem for many that have a great deal of wireless interference on 2.4 GHz while 5 GHz has far less congestion. Additionally, utilizing 802.11n at 5 GHz allows you to achieve much better performance.
If your an Android fan, note that the new generation of Android-based hardware now has the 5 GHz chip as well including devices like the new Google Nexus 4,7 and 10 and the Amazon Kindle Fire HD. Microsoft’s new Surface brand of tablets also has the upgraded hardware chips. But be careful, if you start looking at many of the budget tablets and smartphones, you’ll find that they use the older chips that aren’t compatible at 5GHz. So just a tip, always check the specifications to see that not only does the device use 802.11n — but also dual-band 802.11n at both 2.4 and 5 GHz.
