6.2 Transmit Data Wirelessly
This chapter describes the scenarios of the use cases in which the system does not use
LAN infrastructure to communicate, but only the peer-to-peer mesh network.
6.2.1 Stationary Data Transmission
The mobile network unit stays connected to the same stationary network unit while
transferring the data.
Preconditions:
●
The acquisition unit is in range of the stationary network unit.
●
The stationary network unit is connected to a milling unit.
●
The acquisition unit wants to start transmitting data to the milling unit.
Sequence:
1.
The acquisition unit sends a packet to the connected mobile network unit.
2.
The mobile network unit forwards the packet to the stationary network unit.
3.
The stationary network unit forwards the packet to its connected milling unit.
4.
The milling unit receives the packet.
5.
The milling unit sends an acknowledgement.
6.
This acknowledgement is received and forwarded by the connected stationary
network unit.
7.
The mobile network unit forwards the acknowledgement to the acquisition unit.
Notes:
●
The data that is contained in the packet as was filled by the acquisition unit or
milling unit is not important.
