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 predetermined ranging packet and correlating the raw received bit stream of the response packet with the predetermined bit stream. In one embodiment, the disclosed method applies to the reception of IEEE 802.11 direct sequence spread spectrum DSSS ACK and DSSS CTS packets in response to DSSS data null and DSSS RTS packets respectively, in the 2.4 GHz band.

A network includes a plurality of parent nodes to communicate in a wireless network via a wireless network protocol. A network node establishes a network connection to one of the parent nodes of the plurality of parent nodes in response to received beacons from the parent nodes. A signal analyzer in the network node processes a received signal strength of the beacons and the number of beacons received over a given time period from each of the parent nodes. The signal analyzer selects the parent node by analyzing the received signal strength for a number of beacons received from each parent node with respect to a number of expected beacons transmitted from each parent node of the plurality of parent nodes over the given time period.

According to aspects, a BS may determine presence of a narrow GB or lack of a GB to separate a first RB used for DL transmission from the BS to a first UE and a second RB used for DL transmission from the BS to a second UE. In response to the determination, the BS may transmit, to the first UE, interference information associated with the transmission from the BS to the second UE. According to aspects, a BS may determine a presence of a narrow GB or lack of a GB to separate a first RB used for UL transmission from a first UE to the BS and a second RB used for UL transmission from a second UE to the BS. In response to the determination, the BS may transmit to the first UE, interference information associated with the UL transmission from the second UE to the BS.
