1.2 Data requirements
The below I the data requirement for the various equipments connected in the factory floor and
the office respectively.
1.2.1 Factory floor data requirements
1.2.1.1 Factory machines data requirement
Factory machines =150
Data rate for each machine=15 Mbps for 2 minutes 5 times every hour
Control Machine data rate=15kbps.
Factory floor machines data required=15 Mbps
Every machine generates data for 2 minutes 5 times per hour.
Therefore per hour we have.
-Data =15 Mbps
-Times=5
-Time=(2X60) seconds.

5Communication Systems for Industrial Building
-Total data per machine per hour= (15x5x2x60) Mbps
=9000Mbps
Probability of transmitting a machine = ( 2 x 5 ) / 60
0.1667
Network capacity 1000 Mbps assume in practical 60% is the usable capacity
Maximum number of machines can transmit in parallel = 600/15
= 40
Probability of 40 machine transmitting = ( n
mPm (1- P) n-m
= (
150
40 0.166740 (1- 0.1667) 150-40
=0.00067
Blocking probability of more than 40 machine transmitting = 150
41 ∑ (150
41 0.166741 (1- 0.1667) 150-41
= 1-.99963
= 0.00037
All 150 machines will generate total data= (9000MbpsX150)
= 1, 3500,000 Mbps
1.2.1.2 Supervisor data requirement
There are 10 supervisors with machines that requires 10 Mbps downlink and 100 kbps uplink
Therefore,

6Communication Systems for Industrial Building
Supervisor machine data= 10 Mbps + 100kbps
=10100 kbps
10 supervisors machines data= 10100kbps X 10=101000kbps.
Therefore total factory data= 150 machine data + 10 supervisors data.
Where,
-150 machine data=1, 3500,000 Mbps
-10 supervisors data=10.1 Mbps
- Total factory data=1, 3500,000 Mbps +10.1 Mbps
=135,000,010.1 Mbps
1.2.2 Office floor data requirement
The below are the requirements for data in the office floor.
Total office computers= 250.
Download data rate is 4Mbytes every 10 minutes.
Therefore each computer download data per second =4Mb/(10x60)sec
=0.0066Mbps
= 533334 bits/sec
Upload data rate is 50kbps.
Therefore the Office computer total data = 533334bits + 50 kbps
= 583334 bps.
