Mixed 11b/11g WLAN Performance
Specific questions from iLab
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?
BY dropping the power to a level that is more stable and thus make it harder for interference. Especially if it is not going a long distance.
2. What do access point connectivity statistics collected for the roaming station show?
To me is seems that there is a delay for 2.5 seconds then it moves along for 8 seconds as it moves from one line to the next this could indicate interference it looks like it is still connected
3. What do you think the Wireless LAN control traffic received by the roaming 11b node when it is in the engineering building is composed of?
Looks like bits/seconds
4. How much did our roaming node reduce the total throughput in our heavily loaded WLAN?
Looking at the graph then throughput was at about 14,000,000 bits/sec up to about 10 seconds; the it decreased to 7,500,000 from 10s to 20 s. At about 20 s it increased to about 14,000,000 bits/sec again.
5. What caused this reduction in “goodput” on the 11g WLAN?
The roaming node as you can see as it entered the area and when it left it went back up.
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...
