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.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
