1. A system, comprising:
- at least one logic device configured to;
receive a plurality of data packets transmitted from a hub, each data packet including information identifying one of a plurality of types, wherein each of the plurality of types is associated with one of a plurality of transmission rates and coding schemes, perform a ranging process associated with at least one of the plurality of types, and select a transmission rate and coding scheme based on results of the ranging process.

Abstract
A method for selecting a transmission rate and coding scheme for transmitting data packets from a remote terminal to a hub includes performing a ranging process between the hub and remote terminal. The ranging process may be repeated for each of a number of different transmission rates and coding schemes. The remote terminal may then select the appropriate transmission rate and coding scheme based on the ranging.
