The present invention teaches a system and method for secure network access and group membership in a cooperative network of digital chaos transmissions. The invention involves sensing generated digital chaos sequences as spreading sequences at a transmit side and determining the availability of open channels at a receive side. Further, a broadcast request to join frame from a node on an open channel is transmitted to network manager or coordinator. A network manager or coordinator sends an association/authentication packet, comprised of the reserved digital chaos associated to the unique device id, in response to the request to join frame from a node with a valid identification.

Techniques are disclosed to detect deep fading caused by magnitude drop and rapid phase change on channels within a frequency band of a narrowband wireless radio operating in a BMS-like environment with strong multipath. The techniques may identify an interference channel, a deep fading channel, or a weak signal channel. A channel assessment algorithm may receive packets on one of multiple channels to determine a received signal strength for each packet associated with the channel. The algorithm may determine a PER associated with the channel based on a number of packets received in error and a difference between the received signal strength of each packet and a reference signal strength associated with other channels of the frequency band. The PER may be compared with a PER threshold. The channel may be excluded from use by the wireless radio if the PER for the channel is greater than the PER threshold.
