The newest, most powerful, and most exciting (though still
technically unofficial) standard from the IEEE’s 802.11 working
group is named n. Whereas existing wireless standards route
packets on 20MHz channels, the n standard takes advantage of a
technology called multi-input multi-output (MIMO) to bond two
20MHz channels and increase the capacity to 40MHz. The n
standard can deliver a maximum raw data rate of 540Mbps, and the
net achievable throughput (NAT) is reportedly 10 times faster
than that of 802.11g. Companies that are moving toward employing
VoIP technologies in their day-to-day dealings can take
advantage of this higher speed. Routers that use 802.11n are
easy to spot—they have multiple antennae.  So, what are
802.11n’s drawbacks? The IEEE's 802.11n Task Group recently
introduced for ratification the standard's second draft, which
specifies implementing good-neighbor technology. The 802.11n
standard’s 2.4GHz channel has three non-overlapping 20MHz
channels. Draft 1.0 of the 802.11n standard specifie
