Communication
Information gathered by the PMM is transmitted via a Packet Power radio network. The
P5T3 model may use a radio operating at 2.4GHz, a radio operating in a subset of the range
between 860 and 930MHz (the exact frequencies vary with region – please contact Packet
Power for details), or both depending on how the firmware in the module is configured.
The network operates in a mesh topology. Each device in the network must be within range
of at least one other device in the network. The effective range of the radio in the PMM
varies depending on several factors, including the environment in which the product is used.
Typically, the device has an effective range of 25 to over 100 feet. The PMM will not
transmit effectively if it is installed in an enclosure that blocks radio signals.
Every site where the PMM is deployed must have installed at least one compatible Packet
Power Ethernet Gateway device and associated software to collect data and prepare it for
transmission to approved monitoring and analysis applications.
The rate at which monitoring information is gathered from a PMM depends primarily on the
ratio of the number of PMMs to the number of gateways. It can range from every few
seconds to 100 seconds or more.
Note: In the event of a loss of power to the PMM, energy consumption information
(Wh) for all three channels and the total is retained in non-volatile memory and will be
transmitted when power is restored.
