Mixed 11b/11g WLAN Performance
Specific questions from iLab
Guidelines
* Answer each of the following questions using the sequence and data from the iLab instructions. Answer all questions in full college-level sentences.
1. In your opinion, what is the purpose of our dropping the transmit power to such a low level?
My opinion would have to go with only having 1 node as shown or just a few nodes would be accessing this access point. With dropping the power output will help increase stability if there is a lot of interference ...view middle of the document...

This continued from 21 seconds till 30 seconds or the end of the test.

5. What caused this reduction in “goodput” on the 11g WLAN?
As in question 4 and shows on the graph of the roaming node as how it dropped in data rate instantly when entering the room. I would have to say that this reduction was caused from the roaming node.

General Questions Concerning Mixing 11b and 11g Clients
Guidelines: Answer each of the following questions using knowledge gained from the iLab, readings from the textbook, and individual research on the Web. Answer all questions in full college-level sentences and paragraphs.
6. Supposedly, 802.11b is backwards compatible with 802.11g, yet this lab demonstrates there are significant problems with allowing the two to coexist. What is the primary incompatibility between b and g?
As it stated and from our results in the lab there is a major issue with running both modes. Running both B and G in mixed mode will most likely bring the speeds down on the G nodes to almost around B speeds. The G nodes will not perform at the intended speeds. Might even use connectively between the nodes. (Ciampa, 2013)
7. There is another mechanism besides RTS/CTS that helps the incompatibility. Explain briefly the difference between RTS/CTS and CTS-to-self and when each is used.
This helps with transmitting only when there is no traffic in the air. This helps with slow transmission and get better performance overall. The RTS is request to send it sends out to a node and then the CTS is clear to send the requested information when the air is clear and is able to send data with interruption. The throughput is also reduced with the extra frames. (Ciampa, 2013)
8. What is the protection scheme talked about in the standard? In short, how do 11g nodes know that an 11b node is associating and how is CCK involved?
Those standards are to be followed. From backwards compability to each person being able to use mixed venders hardware and having them work. CCK is invoked with using a 64 8 bit word. This results in higher data rates. (Ciampa, 2013)
9. In addition to the added overhead of the RTS/CTS scheme, what else causes the drop in throughput you see? Are there other factors that...
