There are several good reasons why Wi-Fi 802.11n hasn’t made its way into mobile phones hardware just yet. Increased power consumption is just not worth it if the speed will be limited by other factors such as under-powered CPU or slow-memory anyway.
But when you have a 1GHz Snapdraggon CPU and 448 MB of RAM at your disposal the temptation to include it might just be too big to resist. And HTC obviously succumbed to it when designing the HD2 monster-of-a-handset. Unfortunately they disabled the feature via a software method.
They didn’t do a very good job of hiding it though and it was really a matter of time before someone enabled it. The usual suspects over at xda-delevopers have done the hard work, finding the hidden entry in the registry named 11nModeDisable (duh!). Switching its value from the default 1 to 0 converts your HTC HD2 in a lean mean Wi-Fi n machine. It’s already been tested and works fine.
In case you are not quite familiar, let’s just point the advantages of the 802.11n once again. It doubles the max range both indoors and outdoors, compared to the common 802.11g standard. The theoretical maximum net bitrate is increased more than eleven times to 600 MB/s and the typical throughput is expected to be in the region of 50 to 144 Mbit/s.
Surely all that awesomeness is worth the somewhat shorter battery life, right?
