With the above settings, Bytton will send every hour (3600 seconds) a number of three ping packets to the
remote IP address “74.125.87.106”, with IP source the IP of the SIM connection.
When Bytton LTE does no longer receive a reply to the PING issued, it will restart (reset) the SIM data
connection.
Warning!
The number of ping packets must not be excessively large, and the checking interval must not be too
small, because this could generate a heavy traffic over the data link. See below calculations of the traffic
load for different settings
.
Traffic load calculation:
60 bytes for one ping packet * 3 packets = 180 bytes for one hour
180 * 24 = 4320 bytes for one day
4320 * 31 = 133920 bytes per months
133920 * 12 = 1607040 bytes per year
1607040 / 1024 = 1569.37 KB per year
1569.375 /1024 = 1.53 MB per year.
