|
This is the time it takes to deliver a packet from the source device to the destination device. |
Latency |
|
|
This is a variation of latency. This measures how much the latency of each packet varies from the average. A common result of 802.11 layer 2 retransmissions |
Jitter |
|
|
This results in corrupted data. It is the difference in time between the primary signal and the reflected signals in multipath. |
delay spread |
|
|
What is recommended in high-multipath environments if legacy 802.11a/b/g networks are still deployed? For example, a warehouse full of metal racks with high reflection. |
Indoor standard diversity patch antennas |
|
|
True or False In a high-density environment, such as a high school gymnasium, the use of an omnidirectional antenna will be the best solution for coverage? |
False MIMO patch and panel antennas are often mounted from the ceiling downward to provide tight "sectors" of coverage. the most common use of indoor MIMO patch antennas is for high-density environments. |
|
|
This refers to degradation of performance resulting from overlapping frequency space that occurs due to an improper channel reuse design. |
adjacent channel interference |
|
|
Because of the positioning center frequencies, how many channels can be used while avoiding frequency overlap? |
3 |
|
|
If overlapping coverage cells also have frequency overlap from adjacent cells, what will happen to transmitted frames? |
They will become corrupted. |
