frequency and has an operational range of up to 1.4km between 2 lights.
Should more than 2 lanterns be required to be synchronised the range may be extended for longer
distances as each lantern transmits the data to all adjacent lanterns - causing them to fall into
synchronisation. The only limitation is that no lantern should be more than 1.4km from the next lantern
in the series.
RF Comm-Sync lanterns operate within a peer-to-peer network topology and therefore are not
dependent upon master/slave relationships. This means that lights remain synchronised without use of
master/slavecongurationsandeachlanterninthenetworksharesboththerolesofmasterandslave.
Usinginnovativesoftware,theadditionalpowerconsumptionisminimal,andinmostcongurations
the solar lantern requires only 1.5hrs of direct sunlight per day to retain full working autonomy.
Synchronisation is recommended for lanterns operating with up to 20% duty cycles and in
regions where typical solar irradiation averages 1.5Kwh per day. Flash characters exceeding
this may require lantern intensity adjustment.
Synchronisation is achieved via short-range RF communication between lanterns, and relies
on line-of-sight operation.
