Smart Antennas: A New Boost for Wireless LANs
Design How-To 3/3/2005 Post a comment
The problem with most antennas is that they transmit or receive equally well in all directions, boosting "bad" (interfering) signals just as much as "good" ones. Pulling the good signal out of the bad is a job left to a wireless device's increasingly complex circuitry. Finally, though, antennas are wising up and doing their own share of the work. In this feature article, Gary Legg takes a look at new "smart" antennas and their effects on wireless LANs.
