If you still don't know the difference between the 2.4GHz and 5GHz bands of a simultaneous dual-band router like the Cisco Linksys E3000, you'd better hurry and learn. Another Wi-Fi band is on the way.
Under the agreement, the two groups will co-develop new specifications for the next-generation Wi-Fi standard that works the 60GHz frequency (or band).
Currently, Wi-Fi signals work either in the ever-popular 2.4GHz frequency or the newer 5GHz frequency. The 5GHz is considered cleaner as it doesn't share the same frequency with other wireless home devices such as cordless phones or Bluetooth devices. A dual-band router supports both of them at the same time. Both of these bands offer wireless-N speeds up to 300Mbps, with the possibility of higher speeds up to 750Mbps. In reality, however, these two bands' sustained throughput speeds are still much slower than that of a wired gigabit connection. … Read more
