Patent ID: 7840220

Claim:
A method, comprising: regulating forward error correction (FEC) in a communications network having asymmetric channels that receives requests for wideband data from a mobile client over a LMRS (Land Mobile Radio Service) narrowband channel and delivers wideband data to the mobile client over a wideband channel, comprising: regulating FEC strength as a function of a mobile client location and channel statistics for the mobile client location, wherein the FEC strength is higher while the mobile client is moving and minimal while the mobile client is approximately stationary; varying FEC strength by modifying interleave characteristics based on mobile client speed and location or predicted location; regulating FEC strength at least in part on measured fade statistics of the location or the predicted location; and surveying, in advance of the mobile client reaching the location and the predicted location, the location and predicted location of the mobile client to gather the measured fade statistics to determine needed FEC strength.
