Compute RF Behavior
Calculate each of the five measurements in the project by performing every step in sequence. 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): _____0 km___________ Step 19 (link budget): _____9.439__________
Summary of RF Behavior
In your own words, summarize what you have learned concerning RF behavior from your calculations, readings, and research.
Begin section here dBm measures the power of a signal and the distance a signal can be transmitted depends on the transmitter power. The gain of 9.5358dB is another factor of signal transmission. If you are using an outdoor wireless link, you can expect your coverage to double for every increase of 6dB. If you are indoors, this will be different because of the propagation factors, but an estimate would be a doubled coverage area for every 9dB increased.
The path loss also depends on the antenna gain of the transmitter, how far apart they are and if there are any obstacles. Other factors are the receiving antenna’s gain and the receiver’s sensitivity.
MIMO
Introduction
When looking at radio applications, multiple-input and multiple-output (MIMO) is when multiple antennas are used at both the transmitter and receiver. This technology is useful in wireless applications because it significantly increases the data throughput and link range. The goal is to improve the wireless signal without requiring more bandwidth or power.
The first patent approved was in 1993 and used spatial multiplexing. This was improved by Raleigh, Foschini and Telatar in 1996. At this time is when multiple antennas were put to
