Datasets 4-1 4-2 4-5 to 4-12,

These results are from the rail demo of 5G-PICTURE (www.5g-picture-project.eu). For more details see Deliverable D6.3 where there are also plotted figures.

Dataset 4-1

This dataset is generated by a computer model. The modulation and coding scheme (MCS) of a mmWave link
between an access point (AP) and a station (STA) mounted on the roof of a train is plotted as a function of the
distance between AP and STA. The IEEE 802.11ad single-carrier technology is assumed, and typical conditions
when the range is approximately 350 m – in other words the lowest MCS, MCS1 can be supported up to
this distance. The MCS takes integer values in range 1 to 12.

Dataset 4-2
This dataset is generated by the same computer model as dataset 1. In this case we plot the predicted data
rate (at the application layer in Gbps) and SNR (in dB). In the simulation we assume SNR requirements of an
ideal AWGN channel and adjust the link budget to align with the typical range observed in the field. The SNR
is also capped at a maximum value of 25dB commensurate with a real device.

Datasets 4-5 to 4-12
This is a measured dataset from field testing of the Rail Demo. In the field test the train drives from one end of
the test network to the other (over approximately 2km).
Traffic (TCP iperf3) is generated within each trackside mmWave AP and sent to the train STAs when an association
has been established. The datasets include measurement performed by the two STA of a single train
node (TN), labelled ‘Train-1’. One STA has a radio facing forwards and one is facing backwards (see deliverable
D6.3). These form the two datasets for each parameter. When a STA is not associated (i.e. has no
mmWave link) the parameter is not recorded since no data packets are received. The following parameters
are captured:

Datasets 4-5 and 4-6
The modulation and coding scheme (MCS) of a mmWave link between an AP and each STA is logged.

Datasets 4-7 and 4-8
The SNR is logged. SNR is measured in dB.

Datasets 4-9 and 4-10
The sector ID here indicates which beam has been chosen by the TN radios when receiving packets. A STA
maintains a beambook of 13 directional beams, and a beamforming protocol identify the best beam to use.
The Sector ID is an integer from 1 to 13. Low beam numbers are close to boresight, whilst the highest numbers
(up to 13) imply beam steering up to 45 degrees away from boresight. Odd numbers represent pointing to the
left and even number point to the right.

Datasets 4-11 and 4-12
This plots the received data rate by each STA at the application layer (TCP iperf3). Unit Mbps.
