System and method for rate shifting for wireless VoIP
First Claim
Patent Images
1. A method for rate shifting, comprising:
- operating at an original rate;
acquiring data representative of a current retry rate;
acquiring data representative of a current received signal strength indication;
determining whether to rate shift to a second rate based on the combination of the current retry rate and the current received signal strength indication.

Abstract
A method of rate shifting specially suited for the voice traffic, which differentiates poor channel conditions from a heavily loaded channel of a WLAN and adapts to the network traffic condition and channel condition promptly with low rate of false shifting. Determining when to rate shift is based on a combination of the received signal strength indication and the retry rate.

12. An apparatus, comprising:
-
circuitry for processing wireless signals; and
rate shifting logic coupled to the circuitry for processing wireless signals and operative to control the circuitry for processing wireless signals;
wherein the circuitry for processing signals is operating at an original rate;
wherein the rate shifting logic is operable to acquiring data representative of a current retry rate from the circuitry for processing wireless signals;
wherein the rate shifting logic is operable to acquiring data representative of a current received signal indication from the circuitry for processing wireless signals; and
wherein the rate shifting logic is responsive to determine whether to change to a second rate based on the current retry rate and the current received signal strength indication. - View Dependent Claims (13, 14, 15, 16, 17, 18)
