Method of Transmitting Streaming Multicast Data Over Wireless Networks

HauteLINE^TM Protocol

What is it? 

The HauteLINE^TM protocol is a MAC layer wireless communication protocol developed by HauteSpot Networks. The HauteLINE^TM protocol was designed specifically to support low latency, consistently low delay variation (low jitter), point to point, wireless broadband links for streaming media such as HDTV, IPTV, or high capacity Voice over IP (VOIP).

Implemented as part of the driver for the soft radio used in the HR-IXP line of wireless router products, the HauteLINE^TM protocol significantly modifies standard 802.11a to eliminate unnecessary advertisements, polling, and other “interruptive” wireless traffic and moves management into the wireless headers of each frame. The HauteLINE^TM also provides for consistent frame spacing, eliminating the need for buffering.

Addressing for the HauteLINE^TM protocol is set based on MAC addresses. Each end of the wireless link has the remote end address added to a remote link “virtual interface”. The concepts of association from 802.11a are not used.

Security for the HauteLINE^TM protocol is multi-layered with protocol obscurity being the first layer (can’t connect to it if you can’t see it); second is access control lists on each node, limiting authentication to only the nodes in its list; and finally use of IPSec, PPTP or other tunneling protocol for encapsulating traffic in secure tunneling.

The result is that the HauteLINE ^TM protocol delivers wireless point to point streaming media throughput at rates up to 68 Mbps with no dropped frames and no jitter. These wireless links are suitable for such applications as MPEG or MJPEG streaming of HDTV, high capacity voice links, or other applications where low latency and low jitter are critical.

Further, since the HauteLINE ^TM protocol is part of the driver for the wireless radio modules in the HR-IXP product family, it can be used on all of the frequencies supported by radio modules including: 700MHz, 900MHz, 1.7-1.8GHz, 2.3-2.5GHz, 3.3-3.6GHz, 4.9GHz, and 5.1-6.1GHz.

When used in a multi radio configuration, you can avoid interference through frequency diversity by simply enabling either interface bonding between two radio modules running on different frequencies.

In summary, the HauteLINE ^TM protocol is a wireless layer 2 MAC protocol which is optimized to meet the needs of streaming media applications such as IPTV, HDTV, and VoIP. With support for long range links, over a variety of frequencies, at rates up to 68 Mbps, with no jitter, it is an ideal solution for the broadcast, surveillance, and carrier backhaul markets.
