The YellowjacketPLUS also contains a “Geiger-counter” feature to locate a

Full Spectrum Mode The full spectrum screen has three available TRACES. These traces can be PEAK HOLD and VISIBLE/INVISIBLE. Only one trace can be active at any time. The buttons on the screen below the graph change the settings on the spectrum screen. There is also a PEAK SEARCH button that will put a diamond on the highest point in the spectrum at that time. RSSI and frequency information for that point will then be displayed on top of the graph. The BLINKING HEART on the top right indi

MAC AP/Station Survey Mode Choose “AP List” mode from the main screen to get to the AP List screen. The first screen will “survey” all 14 channels for available AP’s. This screen will show AP’s ONLY. The single channel mode can show all stations. The record number, absolute channel, whether or not it is authorized (if security is enabled), the MAC address, the SSID (for AP’s), the RSSI, and WEP (privacy enabled bit) are shown for each address. Arrows will appear in the header if more than

Multipath / Signal Quality Indicator (“Q” Factor) The bar graph on the lower left hand side of the multipath and the delay spread screens is known as the ‘Q’ factor graph. This graph uses a formula to determine the quality of the direct path and reflections of the signal by determining the ‘fatness’ of the main peak compared to the height of the direct path component. As the direct path gets stronger and sharper, the ‘Q’ factor goes up. As the path gets weaker and fatter, the ‘Q’ factor d

“Geiger-Counter” Mode To find an AP/station using audible sounds as a guide, press up on the joystick to enter the “Geiger-counter” screen. The colors will approach white when nearing and/or pointing directly at an AP or station. The Geiger counter sound will also get stronger with more frequency. Security Screen To go to the security screen, press the security icon from the main screen. The screen shown will appear. You may enter a list of AP’s that are authorized (up to 1000) to be a p

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 th

Yellowjacket PLUS GPS Option The GPS screen of the Yellowjacket Plus provides position and timing information from the Global Positioning System of sat- ellites. The Motorola GPS receiver provides accurate informa- tion after synchronizing with at least 3 of the 24 satellites. The Yellowjacket Plus must have a clear view of a good por- tion of the sky in order to communicate with the GPS satel- lites. The GPS receiver should lock within a few minutes. The only exception is when the unit is tu
