6.2.3 Multiple Streams
The mobile network unit has a connection to several stationary network units that each
are connected to a milling unit. The acquisition unit is transmitting data to all milling
units.
Preconditions:
●
The acquisition unit is in range of two stationary network units A and B.
●
Each stationary network unit is connected to a milling unit.
●
An acquisition unit is transmitting data to a milling unit D using stationary
network unit A.
Sequence:
1.
At one point in time, while the transmission to milling unit D is still ongoing, the
acquisition unit starts a transmission to milling unit C using another stationary
network unit B.
2.
Because the mobile network unit in the acquisition unit now has to support two data
streams, the effective data rate available for both data streams will be lower.
3.
When one of the data streams is stopped, the effective data rate for the remaining
data stream will again be at its maximal level.
Notes:
●
There is only a practical limit to the number of data streams since at a certain
number the effective data rate will no longer be acceptable.
