The Challenge
The
requirements for streaming audio, video and telephony over the
powerline heavily determine the technology approach to network
communications in terms of speed, connectivity and QoS to maintain
constant streams under the most demanding situations. The challenge is
to overcome the hostile powerline environment to deliver:
- continuous high speeds for multimedia applications
- support for multicast and broadcast with low latency
- provisioning of bandwidth and prioritization of the network for quality audio, video and voice transmission
- multiple
applications streaming to multiple nodes simultaneously
- connectivity virtually everywhere without loss of throughput
- support
for a large number of nodes
- low cost of commercialization
- ease
of integration into devices
- compliance
with FCC regulations
The Result
Powerstream™ provides for the optimization of these requirements providing for robust multimedia communications and is the first and only product to properly satisfy these requirements--with comfort and room to spare.
The
Solution
Powerstream™ is a unique and altogether better approach
utilizing powerline-optimized wideband spread-spectrum modulation,
instantaneous "on-the-fly" digital adaptive equalization, rapid
synchronization and error-control coding and powerline optimized token
passing protocols. The foundation of this approach is digital
equalization permitting dynamic adaptation to the inconsistencies of
the powerline. Integrated QoS insures proper handling of high-speed
multimedia including multicast and broadcast.
