wireless n router

are you familiar with wireless a and b and g and n?


actually all of that mode use 802.11 standart networking which categorized based 
on its transfer capability and frequency it used.



the different between wireless n router, and other a/b/g is

• 802.11a transmits frequency at range 5,15Giga hertz - 5,875  Giga hertz can transfer up to 54megabits/s

• 802.11b  transmits frequency at range 2.4Giga hertz  -2,497  Giga hertz        can transfer up to 11megabits/s

• 802.11g  transmits frequency at range 2.4Giga hertz  -2,497  Giga hertz        can transfer up to 54megabits/s

• 802.11n  transmits frequency at range 2.4Ghz or 5Ghz depends on our need (can select each one or works concurrent). can transfer up to 150megabits/s 

the wireless n router have better  coverage area than a/b/g. It is usually up to 200meter with a/b/g, With wireless n router we can reach area of about 250-300m. But carefully, the farther the wifi signal can make loss / degradation off signal packet (higher latency).


and also the wireless n router can have a multiple input multiple output(mimo) -> need antena. That support transfer up to 450mbps.

i also have tested with the tp link mr3020 wireless functionality with my usb wireless wn722n (works on n channel).  It works like a charm :)
