Figure 6: Packet Power Communications Architecture
Power Cable will not transmit effectively if it is installed in an enclosure that entirely blocks
radio signals such as fully enclosed metallic enclosures.
Every site where a Smart Power Cable is deployed must have installed at least one
compatible Packet Power Gateway device and associated software to collect data and
prepare it for transmission to approved monitoring and analysis applications. It is not
necessary for all cables to communicate directly with the Gateway. As long as each cable
can communicate with at least one other cable, and one cable can also communicate with
the Gateway, information from all cables will reach the Gateway.
The rate at which power monitoring information is gathered from a cable depends primarily
on the ratio of the number of cables to the number of gateways. As an example, at a ratio
of 100 cables per Gateway, a Gateway should read from each cable every 5 to 15 seconds.
The system will automatically reallocate network traffic across Gateways when new
Gateways or devices are added.
Note: In the event of a loss of power to a power cable, energy consumption information (Wh) is
retained in non-volatile memory and will be transmitted when power is restored.
