US 11582343

Here's a concise summary of US Patent 11582343:

Title: Devices and methods for multipath communications

Assignee: Competitive Access Systems Inc.

Inventor: Eric M. DeLangis

Filing Date: August 15, 2022

Issue Date: February 14, 2023

Abstract: The patent describes broadband communication devices and methods that use at least two separate communication paths to the network, such as the Internet. These devices can receive data concurrently or separately over these paths. The bandwidth is increased by combining the separate communication paths. The devices utilize packetized data with Voice over Internet Protocol (VoIP) technologies integrated with RF (Radio Frequency) communication technologies.

Plain-Language Overview of Independent Claims:

• Claim 1: This claim describes a residential gateway (RCG) device designed for multipath communication. It includes a POTS (Plain Old Telephone Service) line interface to connect to a conventional telephone network, a modem to establish a network connection over the POTS line, and a wireless interface (like 802.11b/g) for wireless communication. The RCG has a processor that manages all these components. This processor is configured to monitor the wireless interface for other compatible RCGs or wireless access points. When detected, it can use the wireless interface to establish a multilink data connection that combines the bandwidth of multiple POTS lines from different RCGs, or to connect directly to a broadband wireless access point. This allows for increased data transfer speeds.

• Claim 11: This claim focuses on a method for providing multipath communication using the RCG device. The method involves connecting the RCG to a POTS line and a telephone. It then establishes a modem connection over the POTS line for network access. The RCG monitors its wireless interface for other compatible RCGs or wireless access points. Upon detection, the method involves initiating a multilink PPP (Point-to-Point Protocol) session by combining the POTS lines of multiple RCGs or connecting directly to a broadband wireless access point via the wireless interface to achieve higher bandwidth data transfer.
