Summary of RF Behavior
Begin section here
These RF signals have behaviors that can be predicted and detected. They become stronger, and they become weaker. They react to different materials differently, and they can interfere with other signals.
According to the CWNA book It has long been known that a wireless device with multiple receive (Rx) antennas can dramatically improve wireless transmissions by either selecting the stronger incoming signal or combining the individual signals at the receiver. Using multiple antennas at the receiver and transmitter has revolutionized today's wireless communications. Most high-rate wide-area wireless systems, such as 4G mobile phone technologies like Long Term Evolution (LTE) and WiMAX, use MIMO technologies.
Advantages – Disadvantages of MIMO
Because of its advantages, the IEEE made MIMO the heart of 802.11n. The speed of an 802.11n wireless network can be as much as 600 Mbps using MIMO and other enhancements. (By some estimates MIMO alone contributes 40 percent to the increase in speed.)
Multiple-input and multiple-output are currently be in used within the telecommunications and networking by precoding, spatial multiplexing and diversity coding. This Is allows information to be transimitted from one source to multiple devices .
