Finally, the Fire HD is equipped with dual-band Wi-Fi, which can automatically switch between 2.4GHz and 5GHz. What this means is that, if you have a dual-band wireless router, you might see faster downloads and more reliable movie streaming. However, since most people don't have a router that works on 5GHz, you're unlikely to see any benefit.
You might, however, benefit from the dual Wi-Fi antennae in the Fire HD. Also known as MIMO (multiple in, multiple out), this can improve wireless transfer speeds and signal strength so you should be able to use the Fire HD further from your router with fewer droped connections.
We'll bring you a full review of the Fire HD shortly.
