In your own words, summarize what you have learned concerning RF behavior.

Calculations
Step 4 (dBm of 1W): ___30 dBm = 1 W____
Step 11 (max gain): __9.538 dB_________
Step 15 (.11g free space loss): ____0.00001 km_____
Step 17 (.11a free space loss): ______0km__________
Step 19 (link budget): ________9.439_______

Summary of RF Behavior
db measures the power strength of a signal, and the distance that a signal can be transmitted which also depends on the transmitters power. if you are working with an outdoor wireless link you can expect your couverage to double for every ride of 6db

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 – 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.)

MIMO Applications
Describe how MIMO is currently being used within the telecommunications and networking industries, i.e., cellular, WMAN, WWAN , etc.

Future of MIMO
In your opinion, what’s the future for MIMO? Minimum 1 paragraph, 4-5 sentences.
