Patent ID: 7519030

Claim:
A method for use in nodes of a network, the method comprising: receiving one or more packet transmissions from a transmitting node, the packet transmissions including fragments of original frames, the size of the fragments having been based on a fragmentation threshold value set at the transmitting node for a given data rate; producing a signal-to-noise ratio (SNR) value based on the received one or more packet transmissions; and determining a new combination of fragmentation threshold value and data rate value, wherein the determined data rate value of said new combination is a first data rate value at least when the produced SNR value is a first SNR value and is a second data rate value larger than said first data rate value when the produced SNR value is larger than said first SNR value; wherein the fragmentation threshold value of said new combination is determined based on the determined data rate value; and wherein the determined fragmentation threshold value of said new combination is a first fragmentation threshold value at least when the produced SNR value is a particular SNR value and is a second, larger fragmentation threshold value when the produced SNR value is larger than said particular SNR value.
