IEEE 802.11n spec set for first draft vote


Actual throughput at the application level is expected to be 100Mbps, equivalent to 100/10Base T wired Ethernet networks.

The range of 802.11n is also expected to improve by as much as 50 percent, according to McFarland, by using Beam Forming technology which focuses energy in a particular direction on both send and receive.

Another technology called STBC [Space Time Block Coding] will reduce signal drop out by using multiple antennas for redundancy.

This technology in particular is key to enhancing the VOIP user experience.

Finally, packet aggregation and block acknowledgement protocols will reduce power consumption and data collisions in a congested environment by building a so-called super-frame to send multiple packets simultaneously.
