What is the difference between a Wireless N Broadband Router and Wireless G Broadband Router ?
N is the new and upcoming standard that improves on G. (The designations, BTW, refer to IEEE standards 802.11g and 802.11n.) One of the neat things about N is that it’s supposed to actually work *with* multipath propagation instead of passively filtering it as previous standards do, by using antenna diversity (see cited source). Without this improvement, multipath is a type of interference. It’s caused by parts of a signal going in different directions and reflecting from various surfaces (walls, mountains, etc.) and arriving at a receiver at slightly different times. You might recall, if you’ve seen analog over-the-air television, how the images tend to “ghost”; ghosting is caused by multipath. Presumably you’re trying to decide which one to buy/lease/whatever. The 802.11n router may be more expensive. If so, you should consider your needs. Ask yourself whether you need the more advanced 802.11n technology. Are you just surfing the Web, or will you be playing fast-paced online games?
