1. A method of communicating over a network for wireless communications, the method comprising:
- transmitting encoded data from a source device to a destination device via a single path up through a plurality of wireless paths using a random frequency hopping tuning pattern for wireless communications;
pseudo-randomly varying dwell times of the frequency hopping tuning pattern over which the data is transmitted; and
using forward-error correction coding redundancy within a data burst to allow recovery of corrupted data in any partially jammed hop of the transmitted data, including using an adaptive learning process with a variable redundancy rate.

Abstract
A method of communicating over a network for wireless communications is disclosed. The method transmits encoded data from a source device to a destination device via a single path up through a plurality of wireless paths using a random frequency hopping tuning pattern for wireless communications, and pseudo-randomly varies dwell times of the frequency hopping tuning pattern over which the data is transmitted. The network uses forward-error correction coding redundancy within a data burst to allow recovery of corrupted data in any partially jammed hop of the transmitted data.

6. A method for securing data over a network for wireless communications, the method comprising:
-
transmitting encoded data from a source device to a destination device; providing a pseudo-random variable dwell time for at least a first portion of one or more data transmissions over the network using a random frequency hopping tuning pattern for spread-spectrum wireless communications; determining that at least the first portion of the one or more data transmissions is received using forward error correction with a variable redundancy rate; monitoring a prescribed redundancy threshold level once jamming of the data transmissions is detected to discover one or more security breaches in the network; and using the variable redundancy rate to reduce the prescribed redundancy threshold level once a data erasure count from the one or more security breaches is learned to achieve a prescribed data transfer rate for substantially simultaneous encoded data transmissions over the network. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A network system for wireless communications, comprising:
a plurality of wireless communications devices, each of the devices coupled to a plurality of the other devices via corresponding wireless signal links, each of the devices including; a communications transceiver having a processing unit; and a random dwell time generator within the processing unit, the random dwell time generator operable to transmit data-encoded signals on at least one wireless path between the wireless signal links using a random frequency hopping tuning pattern, wherein the random dwell time generator is operable to; pseudo-randomly vary a frequency hopping dwell time of the frequency hopping tuning pattern over which the data-encoded signals are transmitted, and determine a transmission sequence for transmitting a plurality of redundant copies of the data-encoded signals based on a variable period of the dwell time. - View Dependent Claims (15, 16, 17, 18, 19)
