Wireless Routers Buying Guide
January 31, 2008
The 802.11b standard falls under the wireless Ethernet standards series capable of 54 megabits per second (Mbps) maximum within a range of 25 to 75m. Although faster than the 802.11b standard, the problem with 802.11a is that the signal is more prone to obstruction.
This 802.11b has the range of 35 to 120m. The network equipment costs less and works a lot faster than the traditional dial up internet connection. The 802.11n LAN can support a data rate up to 11 (Mbps) maximum. 802.11b routers use a security protocol called the 40bit Wireless Equivalency Privacy (Wep) security protocol but this protocol has a number of holes in it. There is though an update version called 802.11b+ which has patched some of the holes and can give a boosted speed up to 22 Mbps.
The 802.11g, the latest in the IEEE 802.11 series, is the now the most commonly used router standard. This has a range of 35 to 120m. Routers of this standard can in theory give you a whooping 54 Mbps although actual speeds can be lower. This standard uses the Wifi Protected Access (WPA) security protocol which is more robust and reliable. As an 802.11 standard, this exclusively supports Ethernet networks. A new standard in the series called 802.11n is coming and it promises to deliver up to 300 Mbps. Already, some routers that have "Pre-N" or "Mimo" capabilities are in the market.
