2.4.3  GATEWAY EVENT BUFFER 
 
Furthermore the Gateway is equipped with an event buffer to store up to 24k 
events. This memory stores the events in case both communication means 
temporary fails. As soon as the communication is restored the Gateway will transmit 
the buffered events. 
 
 
2.4.4  SENSIT BACKUP BATTERY 
The Gateway can be completed with a backup battery to make 
sure the Gateway stays alive when the mains power fails. This 
backup battery can also been used when the Gateway is 
powered by the public lighting pole. This cyclic use will have 
an influence on the lifetime of the internal lead-acid battery.
