Abstract: A method and devices are disclosed that increase the range of active geo-location from the airborne measuring station as compared with known methods by increasing the effective receive sensitivity of the airborne measuring station. In one embodiment, this may be accomplished by transmitting a burst of predetermined ranging packets and recording the correlation values of each received bit stream of the response packets with the corresponding predetermined bit streams for each of the transmitted ranging packets within a preset reception window. A rolling maximum is then performed on the correlation values in each reception window. At the end of the burst, the rolling maximum results are summed and the time of the peak value is determined.

Abstract: A method and device are disclosed that enable communication between an airborne STA and a ground based AP in the presence of a multitude of other ground based networks that would normally cause such interference that communication would not be possible. A succession of control packets are sent prior to an air to ground communication such that the ground based networks delay their traffic allowing the wanted acknowledgment packet to be received. A succession of control packets are sent followed by a PS poll or data null packet prior to a ground to air communication such that the wanted ground to air packet is sent at a known time and the other ground based networks delay their traffic allowing the wanted ground to air packet to be received.

Abstract: A method and wireless communication device for tracking frequencies of transmitted burst signals. The method includes receiving a burst signal, determining a quality of the burst signal and a carrier frequency of the burst signal, demodulating the burst signal based upon the determined carrier frequency, determining a frequency offset of the burst signal based on the determined carrier frequency, and when the quality of the burst signal exceeds a threshold, calculating a drift window based on the determined frequency offset.

Abstract: A monitoring station and method for increasing a frequency of wireless packet reception. The monitoring station includes a physical layer (PHY) having a plurality of radio frequency (RF) receivers, processing circuitry comprising a processor, and a memory storing instructions that, when executed, configure the processor to control timing offsets of each of the plurality of RF receivers such that each of the plurality of RF receivers has a different timing offset with respect to each other. The monitoring station includes an RF signal router configured to receive an incoming RF signal and route the RF signal to the plurality of RF receivers, and vary at least one of signal gain and signal loss for the incoming RF signal across each of the plurality of RF receivers such that each of the plurality of RF receivers has a different effective noise figure with respect to each other.
