FAQ’s
Can I use all three MOSAIC Gateway backhaul types in a single installation?
Yes.
Will I see a difference as far as data collection between the three MOSAIC Gateway backhaul
configurations?
No, you will not see a difference.
Why would I need to use GPRS in an installation?
GPRS works well in areas where other types of backhaul coverage are not available.
Is the Wi-Fi product 802.11 compliant?
Yes, our Wi-Fi product is 802.11B compliant.
How many MOSAIC FIREFLYs can mesh together?
Typically 1-24 MOSAIC FIREFLYs can communicate directly with each other. The minimum number
of MOSAIC FIREFLY connections needed to continue the mesh is 1. The total number of MOSAIC
FIREFLYs per MOSAIC Gateway should not exceed 1,500.
What is the output power of a MOSAIC FIREFLY?
Transmissions are rated at 250mW.
What is the range of a MOSAIC FIREFLY?
Above ground = approximately ¾ mile (line of sight). Pit mounted (through lid) = 600’ – 1000’
(depending on lid material). Many variables affect range, including topography, meter lid material and
height of the MOSAIC Gateway.
Are the new MOSAIC FIREFLYs compatible with previous legacy FIREFLYs?
No, the transmission frequencies and messages scheme are different; thus a new radio is needed for
handheld, mobile and mesh readings.
Do the MOSAIC FIREFLYs read via the ROADRUNNER MOBILE product?
Yes, a mobile reading mode is available with the same hardware used for Mesh reading.
Will I need different MOSAIC FIREFLYS for Mesh and Mobile functionality?
No, the same hardware used for mobile mode will work with both.
How do I program an MOSAIC FIREFLY?
MOSAIC FIREFLYs used on encoded water meters are automatically set-up. MOSAIC FIREFLYs for
other meters are programmed via 2-way radio communications from a handheld programmer. New
schedules, profile requests and firmware are also loaded via the Mesh.
What does your handheld programming tool look like?
The handheld programmer is a Datamatic, LTD ROADRUNNER CX unit with a MOSAIC 2-way radio.
