Utilization Screen

The utilization screen shows bandwidth utilization for every 802.11b channel. The top of the screen shows the current channel being scanned (highlighted). The chart below shows the utilization from 0 to 100% for channels 1 thru 14. It is color coded to show the percentages for each data rate, as keyed on the bottom of the screen.

The percentages add up the throughput of data at each data rate. For instance, if there were packets at 1Mb/s containing 500,000 bits, then the corresponding percentage at 1Mb/s would be 50%. This would be the same percentage for receiv- ing 5.5 Mb/s on 11 Mb/s packets.

The bars stack on top of each other to reveal no more than 100%.

By tapping the grid, the display toggles between a range of 0-10% and 0-100%. This is for zooming in on low-utilization statistics.

Usage Screen

The usage screen displays the percentage of packets being seen by Yellowjacket PLUS in channels 1 through 14. The graph at the bottom shows RSSI bars for APs detected and is arranged by channel number. Note that the more APs that occupy each channel, the thinner the vertical RSSI bars will become (each bar represents a single AP). The PER/USAGE calculations are now based on a rolling average over the last number (1024) points.
