What is the battery life for the MOSAIC FIREFLY?
When run at a 20 minute mesh interval, 10 plus years.
Is the battery pack replaceable?
Yes, the battery pack can be replaced at Datamatic.
What frequency does the MOSAIC product use?
We use a Frequency Hopping Spread Spectrum (FHSS) over the 902-928 MHz band. 50 separate
frequencies are utilized.
Do you use a licensed frequency?
The radio frequency that Datamatic, LTD uses operates on the ISM band, which is unlicensed.
Does your product provide profiling?
Yes the battery operated MOSAIC FIREFLYS have 240 days of hourly profile data on board.
How do you get the profiling?
Profile data is extracted in two ways, the MOSAIC FIREFLY can be programmed via the mesh to
send an hourly profile packet along with its midnight read, or you can use the RR programmer to
extract the profile data on demand (in development). Keep in mind that requesting profile data over
the Mesh in large quantities will take time and network resources.
How often do I get reads via the Mesh?
Once daily is recommended, but this is user definable. Battery powered MOSAIC FIREFLYs send
in daily readings by default, with the ability to send in up to hourly intervals on selected basis. A
sampling of all meters can be configured to send in higher resolution profile data for statistical
analysis, but can have a negative impact on the mesh network performance.
Is the system 2-way?
Yes, the MOSAIC FIREFLYS can send data and receive commands from the MOSAIC Gateway,
which in turn communicates with the back office utility. MOSAIC FIREFLYs can also
communicate 2-way with a handheld programmer.
What can I do with the 2-way functionality?
Update schedules, configurations, extract profile or other data, and more. Communications can be
broadcast to an entire Mesh or directed to an individual MOSAIC FIREFLY.
Does the MOSAIC system have repeaters?
Yes, low cost repeaters are utilized to bridge the gap between distant MOSAIC FIREFLYs to reduce
network congestion at unavoidable Mesh network bottlenecks or to reduce latency.
How do the MOSAIC FIREFLY repeaters work?
Each MOSAIC FIREFLY already acts as a repeater. Units wired and dedicated as a MOSAIC
FIREFLY repeater utilize the same firmware but do not read a meter and therefore only repeat
readings upstream that they receive.
