[Q] Dual Channel Wifi

---

We don't seem to have a Q and A section yet for the SII. Just ordered mine but still finding out more about it. The Samsung website mentions it has dual channel wifi and that means it is much faster. Sorry but what is dual channel wifi? Can't seem to find a simple explanation. Do you need to have a particular router or anything else to benefit from it?

TIA

you don't need a particular router... it just means it has a wi-fi antenna for the 2.4 ghz band and the 5 ghz band... this means the phone should support wireless A/B/G/N(2.4ghz)/N(5ghz).

While a dual band router would give you all of these options you don't need it....

Summary:
Dual Band WiFi in phone = Able to access any type of WiFi hotspot

I own a dual band router and I was glad when I read a few weeks back that it had indeed dual band wifi, just like my Galaxy Tab. HTC phones don't have it, so it's an advantage in comparison with the HTC Sensation.

Usually the 5GHz band is faster, probably because it's not as common and thus not as crowded as the 2.4GHz band...

it is faster but not necessarily for the reason of less devices using it... honestly when it comes down to it it's band width... higher frequency typically = greater bandwidth
