NETW360, Professor’s Name Mario Kosseifi Current Date July 15, 2012 Lab #2 Part 1, Antennas Lab Report Case Project 3-1 Antenna Type Using the internet and other resources, research the different types of antennas that are included under the three main categories: omni-directional, semi-directional, and highly-directional. Draw or print an example of each type and summarize when it is used, what is its maximum transmission distance, and it’s advantages and disadvantages. Omni-Directional [pic] When it is used?

This antenna can be used for indoor and outdoor access points. It is an excellent solution for RV parks, Marinas, Resort Wi-Fi, and other general outdoor area where other wireless access is needed but unable to be achieved by the small antennas on a router. What is its maximum transmission distance? The range of this antenna is 3000 feet. However, a longer rage is possible with additional antennas on the receiving end. Advantages and disadvantages? The main advantage to this antenna is that you can receive wireless signal in areas that were not available before.

Everyone has heard of internet “Cafes”, but with this antenna you could make an internet “Cafe” literally in the middle of a campground. The disadvantage is that trees, building and hills can reduce the signal and in somecases can completely stop the signal from getting through. Also, to get this antenna high enough to cover some areas the length of the coax cable will reduce the signal; thus making the antenna less effective. Semi-Directional [pic] When it is used? Semi-directional antennas are ideally suited for short and medium range bridging.

If you want to connect two office buildings that are across the street from one another and need to share a network connection semi-directional would be a good choice. Or if you have a long narrow room where you need coverage throughout the whole room you can mount the antenna on an end wall. This is because the side-to side signal will not travel as far but the forward signal will travel quite far. What is its maximum transmission distance? Semi-directional range can vary greatly but is commonly used in situations that call for a range of a few hundred feet to two miles.

Advantages and disadvantages? The main advantage of a semi-directional antenna is that in some cases a semi-directional antenna can provide such a long range coverage that they eliminate the need for multiple access points. The main disadvantage is that if you need coverage over a large open area, such as a cubical office where the entire floor is open, a semi-directional antenna would not be the best choice because not every computer will receive coverage. Highly-Directional [pic] When it is used?

It’s main usage is for point-to-point communication links where wired or other directional wireless coverage is not possible. What is its maximum transmission distance? Highly-directional antennas can operate at a range of up to 35 miles. Advantages and disadvantages? The main advantage is if you need to transmit wireless signal over a very long range without the signal going all over. Such as a person that is quite wealthy, they may have their own private island and want internet connectivity, but does not want to go with satellite internet and wired connectivity is out of the question.

Another advantage is that if you are located in a building where wireless signal is very hard to get, a highly-directional signal may be the answer because since it is so focused in such a small narrow margin it may be able to basically blast through the wall. The main disadvantage is that the dish antenna is subject to damage from weather, especially if not mounted correctly. Highly directional antennas, for the most part, require a clear line-of-sight between ends.

Determining the behavior of an RF signal can be an aid when troubleshooting a WLAN that does not function properly. In this project you will use several online calculators to computer the RF behavior. 4. 30dBm 7. 8. 4 11. -81. 538 19. -5. 474469367710745 |Name |Power Output | |Cell Phone |. 6 W | |Cordless phone |10 mW | |Garage Door Opener |100 W |
