Low Voltage Systems

The Gridline low voltage system will support Customer Premise Equipment units (CPEs) at the business or consumer location. Our PLC (Power Line Communications) low voltage coupler is positioned at the electric service pole. The low voltage PLC Coupler superimposes broadband signals into a 110V electric power line, and removes broadband signals from the same electrical line which enables the clean delivery of high speed broadband to the end user. While providing the high speed Internet connection, the Gridline delivery system can provide voice services over the Internet (VoIP), with optional VoIP equipment and video on demand. The system can serve multi-unit homes, a building with many apartments or offices. The current data rate for Gridline Communications Corp.'s low voltage is 14 Mbps-25 Mbps, and can reach up to 5 miles. The low voltage PLC will be set to operate with Discreet Multi-Tone (DMT) modulation, with adaptive bit loading for each sub channel. The PLC repeaters can be used to connect homes further apart from the substation to extend range.

PLC CPE equipment will be able to obtain instant access to the Internet and also to the home network through the power outlet. Each CPE has its own security feature, due to added individual key encryption. Other features of PLC CPEs include:

• Packet based data communication
• Readiness for value added service features such as VoIP, video conferencing, video on demand (VOD), and security monitoring for homes and offices

The Gridline CPE specification will include the ability to support standard hub and router hardware. Other target specification for our CPE is:

• Data rate of between 14 Mbps and 25 Mbps, although practical average data rate need for most end-users, will be in the range of 1.5 Mbps and 4 Mbps
• Reach: of up to 5 miles
• Channel specific adaptive loading
• Forward error correction
• Individual encryption
• USB
• Plug and play capabilities with Microsoft Windows®

A PLC Repeater is used to relay frames between the PLC router, and the CPE. It will automatically detect existing PLC device, with a very simple installation process. Our PLC router can support 5 to 10 repeaters both extending the range and number of end user connections.

Our PLC low voltage network management software and server is responsible for monitoring and management of the network and basic remote operation of the network (power reset). iPLC low voltage network management software includes a proprietary simple network management protocol ("SNMP") which is responsible for subscriber registration, authentication, and activity monitoring.
