Summary of Benefits

Background

• Multiple connectivity technologies are needed due to the wide variety of applications, regions, environments and topologies.

• Each of these different technologies has a unique interface to higher layer entities.

• Software and hardware design complexities in multi-connectivity devices.

Goal

• Provide a common interface to widely deployed home networking technologies.

1905.1 MAC Addressing

• Between 1905.1 Devices, MAC Service Data Units (MSDU) and CTRL Message Data Units (CMDU) are sent over the 1905.1 network using 1905.1 AL MAC Address as DA.

• Underlying interfaces may communicate using their generic MAC addresses for control purposes.

Features

• Topology discovery: query(unicast), response(unicast), notification(relayed multicast)

• Security setup: push button configuration, user configured passphrase/key, near-field communication network key

• Access point auto-configuration: The AP autoconfiguration process uses CMDUs to convey IEEE 802.11 parameters from a registrar to an AP enrollee to set up the initial configuration or renew an existing configuration of an IEEE 802.11 interface.

Main Use Cases

• Multipath delivery

• Range Extension

Summary of Benefits

• Ease of Use: Use common setup procedures for adding devices to a network, establishing secure links, implementing QoS, and managing the network.

• Fallback: When a link goes down temporarily or is congested, an alternative route is available.

• Aggregated Throughput: Use multiple interfaces for maximizing throughput.

• Multiple Simultaneous Streams: With applications such as interactive TV, even a single person may be watching multiple streams simultaneously.

Summary of Benefits

• Load Balancing: Intelligently distribute multiple video streams over different paths to limit congestion and maintain reliability.

• QoS: Uniformed Prioritized QoS over multiple technologies.

• Security: 1905.1 allows devices to be configured the same way with a simple button push, for example.

• Advanced Diagnostics: The overall network monitors itself.

• Mobility: Wireless connectivity supports mobile handsets, and tablets.

• Universal Connectivity: Can connect to the hybrid network from every room in the house without having to be aware of which part of the network their device is currently interfacing.
