MIXED 11B/11G WLAN PERFORMANCE
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 transmit power, the chances of the transmission point interfering with other points is lowered.
2. What do access point connectivity statistics collected for the roaming station show?
In my simulation the access point connectivity appeared to remain the same during the 30 second simulation.
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?
The 11b roaming node is composed of traffic from both 11b and 11g.
4. How much did our roaming node reduce the total throughput in our heavily loaded WLAN?
It appears that the roaming node reduced the throughput at about 3,900,000 bits per second.
5. What caused this reduction in “good put” on the 11g WLAN?
The interference from the roaming node entering the area caused the reduction.
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?
Both the b and g use the same three channels for data, which in turn can cause a slowdown of network traffic on an already crowded system (Black Box)....
