antennas is to achieve higher capacity noting that advanced solutions provide higher capacity than basic solutions. IMEC — Multiple antenna systems are the key to the high-capacity wireless universe. Indeed, they allow increasing the rate, improving the robustness, or accommodating more users in the cell. Georgia Institute of Technology — A smart antenna is an array of antenna elements connected to a digital signal processor IEC — A smart antenna system combines multiple antenna elements with a signal-processing capability to optimize its radiation and/or reception pattern automatically in response to the signal environment. Spatial division multiple access (SDMA) — Among the most sophisticated utilizations of smart antenna technology is SDMA, which employs advanced processing techniques to, in effect, locate and track fixed or mobile terminals, adaptively steering transmission signals toward users and away from interferers. SearchMobileComputing.com — A smart antenna is a digital wireless communications antenna system that takes advantage of diversity effect at the source (transmitter), the destination (receiver), or both. MIMO is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). Smart Antennas Research Group, Stanford Univ. — Our research goal is to advance the state-of-the-art in the applications of multiple antennas and space-time signal processing in mobile wireless networks, and to improve network performance and economics. CDG — Smart antennas provide greater capacity and performance benefits than standard antennas because they can be used to customize and fine-tune antenna coverage patterns that match the traffic conditions in a wireless network or that are better suited for complex radio frequency (RF) environments. MIMO employs multiple, spatially separated antennas (at both TX and RX) to take advantage of these "virtual wires" and transfer more data. Nortel — MIMO is an antenna technology that is used both in transmission and receiver equipment for wireless radio communication. MIMO is the only advanced antenna technology that simultaneously offers high bandwidth, improved range, and high mobility at a lower cost. Visant Strategies — Intelligent antennas are antenna systems that use some sort of computational or electronic resource to enhance system performance. According to the amounts of intelligence employed, antenna diversity represents the simplest form in the progressive complexity chain, followed by basic beamforming, which is the process of narrowing radiated energy, which is then followed by the more complex space-time processing and finally by MIMO.
