Important Things to Know
About 802.11n

YES - 802.11n Access Points and 802.11n Broadband Routers can deliver TCP/IP throughput in excess of 200 Mbps. The effective range and speed of 802.11n equipment exceeds that of earlier 802.11a/b/g but only an optimal 802.11n system design will maximize those benefits.

What is 802.11n?

How 802.11n Evolved and Where It Is Today

 

Should You Deploy 802.11n or Will 802.11g Be Sufficient?

There's a question of sufficiency and another, separate question of suitability. The first thing to consider is whether or not it's suitable to implement 802.11n as a "Greenfield" deployment. The term "Greenfield" when applied to 802.11n means that only 802.11n devices will be supported. No 802.11b, 802.11g or 802.11a. That means that any older notebook computers that use 2.4 GHz 802.11g won't be supported. Portable devices like the Apple iPhone won't connect to the WLAN. An 802.11n Greenfield deployment means "only 802.11n."

One common approach that Connect802 has used successfully with 802.11n implementations is to utilize dual-radio access points which support only 802.11n in the 5 GHz band and support only 802.11b/g radios in the 2.4 GHz band. This allows for a Greenfield 5 GHz implementation (which avoids the performance degradation associated with mixed-mode designs) but still allows legacy 802.11b/g devices to have network connectivity. It's the best of both worlds!

 
What Makes 802.11n Faster Than 802.11g and 802.11a?
 
 
 

You'll find numerous Web references and reviews of the IEEE 802.11n standards and 802.11n equipment, 802.11n products and 802.11n services that are available. Below are some targeted discussions to provide you with additional perspective on how an 802.11n solution can be implemented to meet your requirements for a secure, easy-to-manage wireless LAN system.

The 802.11 family includes over-the-air modulation techniques that use the same basic protocol. The most popular are those defined by the 802.11b and 802.11g protocols, and are amendments to the original standard. 802.11-1997 was the first wireless networking standard, but 802.11b was the first widely accepted one, followed by 802.11g and 802.11n. Security was originally purposefully weak due to export requirements of some governments, and was later enhanced via the 802.11i amendment after governmental and legislative changes. 802.11n is a new multi-streaming modulation technique. Other standards in the family (c–f, h, j) are service amendments and extensions or corrections to previous specifications.
The IEEE 802.11n standards were ratified by the IEEE (Institute of Electrical and Electronics Engineers) on September 11th, 2009. The Wi-Fi alliance, which certifies 802.11 product interoperability, confirmed that 802.11 certification would not have to change as a result of anything in the final 802.11n standard.
