SYNCHRONIZING DATA TRANSMISSION BETWEEN A WIRELESS NETWORK AND A WIRED NETWORK
First Claim
1. A method to synchronize timing of data transmissions between wireless and wired networks using a combined wireless gateway and cable modem, comprising:
- sending an indicator prior to a look-ahead time period;
transmitting a poll to a wireless device upon receiving the indicator;
receiving data from the wireless device;
encapsulating the data in a DOCSIS format to generate a DOCSIS frame; and
transmitting the DOCSIS frame at a start of a next transmit opportunity to a cable modem termination system (CMTS);
wherein the look-ahead time period is a time period from transmitting the indicator to transmitting the DOCSIS frame.

Abstract
Methods, systems and computer program products to synchronize timing of data transmissions between wireless and wired networks using a combined wireless gateway and cable modem are provided herein. The method includes the step of generating an indicator prior to a look-ahead time period and transmitting a poll to a wireless device upon sending the indicator. The look-ahead time period is a time period from transmitting the indicator to transmitting the DOCSIS frame. The method further includes the step of receiving data from the wireless device and encapsulating the data in a DOCSIS format to generate a DOCSIS frame. The method also includes transmitting the DOCSIS frame at a start of a next transmit opportunity to a cable modem termination system (CMTS).
