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.

MIMO

Introduction

What is MIMO? What’s the history? What issues are addressed? What are the goals?

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 and Disadvantages of MIMO

Identify all advantages and 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.)
