Abstract

Described herein is a system and method for determining one or more data modulation profiles for one or more devices. The system and method described herein may measure signal quality, such as a modulation error ratio (MER), signal-to-noise ratio (SNR), receive power, transmit power, etc. Based on the signal quality, the system may determine one or more data modulation profile(s) (e.g., quadrature amplitude modulation (QAM) profiles) for a subcarrier, a plurality of subcarriers, a device, and/or a grouping of devices.

Claims

exact text as granted — not AI-modified

1 . A method comprising:
 configuring a first modulation profile for a user device, wherein the user device communicates with a termination system via a subcarrier using the first modulation profile;   measuring a signal quality of the user device; and   
       configuring, based on the signal quality, a second modulation profile for the user device, wherein the user device communicates with the termination system via the subcarrier using the second modulation profile.
