New 802.11n Wireless Routers

As more products hit store shelves with the promise of Wi-Fi connectivity, more households and small businesses are getting rid of their wired networks. However, while 802.11g has been the standard for quite some time, 802.11n — in beta form — has begun to replace 802.11g with its faster speeds and longer range. Netgear’s “n” router costs $125; its older “g” router is $80.

These so-called pre-N or Super G routers employ MIMO, a wireless scheme that makes greater throughput and faster data transfer rates over their wireless network

802.11n is supposed to offer two huge advantages over the popular “b” and “g” types of routers: 5 times the speed and 15 times the range. It would mean, for example, that the signal from just one transmitter — one wireless router, to use the technical term — could fill every room in your house with glorious waves of data.

The nominal connection speeds, as opposed to real-world throughput–of up to 300 megabits per second (compared with 54 mbps for standard 802.11g) and extended range (thanks to multiple smart antennas), 802.11n Wi-Fi is the first Wi-Fi technology that can rival wired 100-mbps Ethernet in performance. Upgrading your home router to 802.11n is thus one of the quickest and easiest ways to improve your network. The new 802.11n spec uses the 5GHz spectrum to reduce the interference issues found on 802.11g routers using the 2.4GHz spectrum.
