7.3
Multiple streams
The mobile network unit has connections to several stationary network
units that each are connected to a milling unit. The acquisition unit sends
data to all milling units.
Requirements:
● 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 two data streams is stopped, the effective data rate
for the remaining data stream will again be at its maximal level.
IMPORTANT
There is only a practical limit to the number of data streams, because at
a certain number the effective data rate will no longer be acceptable.
