"The Align family is a family of single stream 11n products,
according to the IEEE specs, which are ideal for upgrading legacy
g. All those products that fill the entry-level shelves and PCs--we
are suggesting that we can bring 11n performance and power at costs
similar to g. In 2009, we’re promoting this new family as a
way to move forward from legacy g to 11n.," Todd Antes, VP
Marketing at Atheros, told Wi-FiPlanet.
"Atheros says its Align solutions deliver up to 150 Mbps PHY
rates and leverage the efficiencies of the 802.11n media access
control (MAC) technology to achieve actual throughput levels up to
five times that of legacy 802.11g. The higher throughput of
1-stream products can improve network efficiency by occupying the
wireless channel for shorter periods than slower 11g devices. This
reduces congestion and increases the capacity for additional
wireless devices, says Antes."
