Connectivity to multiple external cellular communication protocols GSM/GPRS/CDMA/WiMax

Direct communication of pricing information to the gateway. Gateway initiates the demand response functions.

Ensure continuity between the home network and in home connected devices using various communication standards and the external world based on inexpensive cellular based two-way communication. Use Dual factor communication.

Encrypted securitized data transmission Connectivity to a limited number of HAN communication protocols including

Zigbee/HomePlug/hardwired options Control ALL Home automation functions receiving external communication

from public authorities Security (e.g. Amber Alerts)/Public Alerts/Weather warnings Energy Medical

Allow connectivity to all existing home automation protocols including security systems/home area networks

Always connected to external data and internal management control Non intrusive to the end user.

standardized operability

CONFIDENTIAL

Customer remote access via subscription to both push (e.g. PDA) and Pull (e.g. cellular portal)

Enable and empower end user to receive data and manage functions based on information received remotely in real time or a schedule.

Offers automated conservation modes/schedules. Compatibility with inexpensive fixed income automated

conservation devices with HAN environment. Backward compatibility to all Thermostats and AMI systems. Conversion of existing thermostats to smart thermostat status via

wireless relay interface communicating to the gateway. Allow for utility initiated automatic load management based on

pre-defined profiles.

Plug and Play connectivity or very limited requirement for professional installation.

Communicates energy savings to end user. Remote maintenance/operation of deployed devices/data via

appropriate head end system(s) Expandable ports for additional functionality (wired or wireless) Scalability of gateway solution to allow other industries (health,

security, etc..) to offer services and products to offset cost to utility and end user.

Demand Response

The gateway communicates

signals from the web or

smartphone to Wireless Relays

and receivesConfirmation

and commands in return

The wireless gateway communicates energy consumption to wireless devices. In turn the gateway controls all elements of Home Energy Management including HVAC equipment, as well as appliances and lighting.
