Why use Yitran PLC?Why use Yitran PLC?

Because it is the most reliable PLC communication available today.This means: Yitran’s technology enables 100% connectivity even with

the farthest units.Yitran’s DCSK patented modulation technique (US patent #6,064,695)

overcomes the challenges characteristic of the power line medium. Yitran’s technology significantly surpasses the performance of

compatible modems.Yitran’s distributed MAC integrates patented and patent pending

enhancements specially adapted for the power line medium.Yitran's solutions enable opportunities for utilities to offer new

services, features and products; cut costs of current services; fully automate manual processes and procedures; improve current products; monitor and collect valuable data; offer remote service options and create new business and revenue streams utilizing the existing infrastructure.

Utilities and PLC ?Utilities and PLC ?

The increase in public demand for energy creates the need for Energy Saving and Energy Management procedures.Utilities can lower cost by reading meters remotely, charging according to time of use or according to level of power used, automating power failure recovery and lowering the investments in new power stations. Utilities can increase revenue by offering more services to the customers (besides just offering power).In some areas of the world, 30% and more of the electricity is stolen. AMR/AMM is used to detect electricity looting.

The worldwide potential market for Automatic Meter Reading (AMR) is more than 1B meters. Almost EVERY power utility in the world is under pilots or trials to use AMR. The estimate is that most will use PLC.

Combining PLC with WirelessCombining PLC with Wireless

Two products are under development:

1. HomePlug C&C-ZigBee bridge, an end-user module that will transparently bridge the HomePlug C&C and ZigBee networks to create an integrated single virtual control network. When appropriately used within the HPCC/ZigBee networks, all the wireless devices are brought into the line of sight of each other irrespective of the geographical distribution of these devices in a home or building.

2. Unified PLC-ZigBee network (Y-Net and PLC-802.15.4 Module) YITRAN’s long term goal is to become a COMMAND CONTROL company by supplying technologies in the W/L space as well.

Combining ZigBee technology with PLC will be the perfect solution to cover home needs for Command and Control.
