??Introduction¶

The European project called “METIS” has defined twelve test cases (TCs) to cover the practical applications of 5G system and simulation needs for the coming 5G system. For this reason, they have made available “Ray tracing data” from their website. The provided data is used here to perform simulation with PyLayers The following code displays all available data.

import os
basename =os.environ['BASENAME']
for root, dirs, files in os.walk(basename+'/meas/Metis'):
    print root
    if len(dirs)==0:
        for f in files:
            pass
            filename = root+'/'+f
            print filename.replace(basename,'')
    for d in dirs:
            for f in files:
            print d+f

Test Case 1: Virtual reality office¶

Test case 1, the virtual reality office, is an indoor test case where very high data rates are investigated targeting also implementations at a reasonable cost. A realistic office environmental model for this test case is attained by explicitly considering walls, screens, desks, chairs and people.

The environmental model geometry, is given by the dimensions of the rooms, cubicle offices and tables. The indoor office model is illustrated in the following two and three-dimensional figures.

alt text¶

The above figures available from METIS’ deliverable [D6.1] (https://www.metis2020.com/wp-content/uploads/deliverables/METIS_D6.1_v1.pdf) show the initial room size of 20 m x 10 m, however it was later scaled to 25 m x 12.5 m. The room size of 25 m x 12.5 m was used to obtained the ray tracing data available from METIS’ website.

The respective heights and materials of these objects are given in the following table.

from tabulate import tabulate

table = [["Object","Height[m]","Material"],["Room",2.9,"Concrete"],["Cubicle",1.5,"Wood"],["Table",1.5,"Wood"]]
print tabulate(table)

-------  ---------  --------
Object   Height[m]  Material
Room     2.9        Concrete
Cubicle  1.5        Wood
Table    1.5        Wood
-------  ---------  --------

Deployment considerations¶

In test case 1, five APs and 1176 UEs with respectively 2.85 and 75cm of height are used. The deployment baseline is one main base station ceiling-mounted with fiber backhaul with UEs, as desktop computers, tablets and smartphones, in either a sitting or standing position. A coverage base station working at frequencies below 6 GHz will be located in the center of the office whereas other access points could be deployed to give further capacity to the system. Using available ray tracing data from Metis’ website we represent the actual scenario in the next figure. The coordinates of the APs are as follows: AP1 (2.5, 2.5, 2.85), AP2 (2.5, 10, 2.85), AP3 (22.5, 10, 2.85), AP4 (22.5, 2.5, 2.85), AP5 (12.5, 6.25, 2.85). This scenario is assumed to be isolated from outside interferences.

Parameters of AP files¶

In the generation of the AP files the following parameters are used:

FREQUENCY = 60000.000000
# The carrier frequency in MHz, i.e. 60000 is 60 GHz.

MAX_NUMBER_REF=2

# The number of reflections allowed for the propagation paths.

#PTS_DENSITY = 0.000000

#This is the number of point sources per square meter [m^2], the point sources
#are 80% on walls and 20% in space (uniformly in the 3D space of the whole
#room). A point source is a point that reflects in any direction, hence any AP
#and UE pair that has line-of-sight path to a point source has a propagation
#path using this point source.

PTS_AVERAGE_ATTENUATION=18.000000

PTS_SIGMA=5.000000

#These two parameters determine the attenuation [in dB] of the propagation path using a point source, the attenuation is a normal distributed random variable with the above parameters, i.e. mean PTS_AVERAGE_ATTENUATION and standard deviation PTS_SIGMA.

# FORMAT =  [xAp yAp zAp xUe yUe zUe PATHGAIN]

#This is the format of the table, i.e. the three first values [xAp yAp zAp] are the AP position and the next three [xUe yUe zUe] is the UE position the last is the pathgain in dB.

Propagation model (Environment and Link Topology)¶

Main propagation link type is the Base Station to Mobile Station (BS-UE) link and the propagation link topology is I2I (indoor to indoor). Furthermore, D2D links can be considered for the big volume data sharing between users in the same office room. Line-of-Sight (LOS) links can be assumed to dominate, but also reflected waves need to be taken into account due to shadowing effects. For this scenario blocking by humans may have a severe impact, particularly in the high frequency range. To obtain propagation models at higher frequency regions such as millimeter Waves (mmW), for instance from 30 to 300GHz, ray tracing could be used. In order to perform the ray tracing, a maximum number of reflections, as well as distance dependencies of free-space loss and material constants for penetration and reflection losses need to be specified. Therefore, the propagation characteristics of the used materials are given by METIS in [D6.1] as following:

table = [["Material","realPermittivity","imagPermittivity","Penetration Loss"],["Concrete",6.14,0.3,71.5],["Wood",1.64,0.11,8.6],]
print tabulate(table)

--------  ----------------  ----------------  ----------------
Material  realPermittivity  imagPermittivity  Penetration Loss
Concrete  6.14              0.3               71.5
Wood      1.64              0.11              8.6
--------  ----------------  ----------------  ----------------

Given ????? and ????? which denote the real and the imaginary part of the permitivity, the complex relative permitivity of the material is computed by: ??=?????-i?????.

Material Validation¶

These complex values are then used to compute the complex amplitude of the signal after the reflection. This is known as the validation of the materials as shown in the following figures. The next library is first imported from PyLayers.

from pylayers.antprop.slab import *

Firsly, we check the available material from SlabDB() which is (slab data based) of PyLayers.

S=SlabDB()

At that stage the oject is empty.

List of Slabs
-----------------------------

The materials “CONCRETE_TC1_METIS” and “WOOD_TC1_METIS” are not included in the data base, therefore the two materials are added in the next cell.

S.mat.add(name='CONCRETE_TC1_METIS',cval=6.14-1j*0.3,typ='reim',fGHz=60)
S.mat.add(name='WOOD_TC1_METIS',cval=1.64-0.11*1j,typ='reim',fGHz=60)

Then, the electromagnetics parameters of the added materials are displayed as following:

S.mat['CONCRETE_TC1_METIS']

{'a': None,
 'b': None,
 'c': None,
 'd': None,
 'epr': array(6.14),
 'epr2': array(-0.3),
 'epsr': (6.14-0.3j),
 'fGHz': 60,
 'mur': 1,
 'n': (2.478641222659018-0.060517027889612891j),
 'name': 'CONCRETE_TC1_METIS',
 'roughness': 0,
 'sigma': 1.0011123470522802}

S.mat['WOOD_TC1_METIS']

{'a': None,
 'b': None,
 'c': None,
 'd': None,
 'epr': array(1.64),
 'epr2': array(-0.11),
 'epsr': (1.64-0.11j),
 'fGHz': 60,
 'mur': 1,
 'n': (1.2813439984332509-0.042923680188341806j),
 'name': 'WOOD_TC1_METIS',
 'roughness': 0,
 'sigma': 0.36707452725250272}

The next cell adds the thickness of the materials.

S.add('CONCRETE_TC1_METIS',lmatname=['CONCRETE_TC1_METIS'],lthick=[0.108])
S.add('WOOD_TC1_METIS',lmatname=['WOOD_TC1_METIS'],lthick=[0.019])

Finally, the data base is displayed to check the existence of the added materials.

List of Slabs
-----------------------------

CONCRETE_TC1_METIS : CONCRETE_TC1_METIS | [0.108]
       black 1
       epr :6.14    sigma : 1.00111234705
WOOD_TC1_METIS : WOOD_TC1_METIS | [0.019]
       black 1
       epr :1.64    sigma : 0.367074527253

After adding the materials with their characteristics, they are then evaluated within the used frequency band and angle range.

fGHz= np.arange(59,61,0.1)
theta = np.arange(0,np.pi/2,0.01)
S['CONCRETE_TC1_METIS'].eval(fGHz,theta)
S['WOOD_TC1_METIS'].eval(fGHz,theta)

The material validation consists of plotting Reflection and Transmission Coefficients and compare with the Penetration loss given in the above table.

f,a=S['CONCRETE_TC1_METIS'].plotwrt(var='f')

../../_images/MetisRayTracing60GHzforTC1_36_0.png

f,a=S['WOOD_TC1_METIS'].plotwrt(var='f')

../../_images/MetisRayTracing60GHzforTC1_37_0.png

The above figures show the amplitude of the reflection (R) and transmission (T) coefficients as a function of the frequency.

It can be seen that for the “concrete material” both transmission coefficients (perpendicular and parallel) have an amplitude which is roughly equivalent to the penetration loss given in the above table (71.5 dB). And the same observation is obtained with the wood where the given penetration loss is 8.6 dB.

Regarding the reflection coefficients for the “wood material”, it is observed that both amplitudes have a slight decrease from -17.13 dB to -18,85 dB within the specified frequency band. Finally, the reflection coefficients for the concrete material have a constant amplitude of -9 dB from 59 to 61GHz.

In the next graph, we plot the frequency of both coefficients as a function of the angle.

fig = plt.figure(figsize=(10,10))
S['CONCRETE_TC1_METIS'].pcolor()

../../_images/MetisRayTracing60GHzforTC1_39_0.png

fig = plt.figure(figsize=(10,10))
S['WOOD_TC1_METIS'].pcolor()

../../_images/MetisRayTracing60GHzforTC1_40_0.png

The above graphs describe the behavior of the waves when they arrive on a given surface. Some waves are reflected and others are refracted. It can be seen that \(R_{\perp}\) and \(R_{\para}\) are complementary to \(T_{\perp}\) and \(T_{\para}\) respectively.

Now we represent the amplitudes of both coefficients in the different interfaces (air/concrete and air/wood) as shown in the next figures.

sl = SlabDB(filemat='matDB.ini',fileslab='slabDB.ini')
mat   = sl.mat
lmat  = [mat['AIR'],mat['CONCRETE_TC1_METIS']]
II    = MatInterface(lmat,0,fGHz,theta)
II.RT()
fig,ax = II.plotwrt(var='f',kv=10,typ=['m'])
plt.tight_layout()

../../_images/MetisRayTracing60GHzforTC1_42_0.png

The graph revealed that both reflections coefficients of the air/concrete interface have a constant amplitude of 0.4 dB over the frequency band. However, the transmission coefficients have a difference of amplitude which equal to 0.8 dB.

sl = SlabDB(filemat='matDB.ini',fileslab='slabDB.ini')
mat   = sl.mat
lmat  = [mat['AIR'],mat['WOOD_TC1_METIS']]
II    = MatInterface(lmat,0,fGHz,theta)
II.RT()
fig,ax = II.plotwrt(var='a',kv=10,typ=['m'])
plt.tight_layout()

../../_images/MetisRayTracing60GHzforTC1_44_0.png

As regards to the air/wood interface, it is clear that the amplitude of both reflections and transmission coefficients

increased roughly from 0.12 dB to 1 dB and from 1 dB to 2 dB respectively.

The path gain of each AP and free-space path loss are shown in the next figure.

plt.tight_layout()
#plt.savefig('path_gain_tc1')

../../_images/MetisRayTracing60GHzforTC1_48_0.png

The above graph shows the path gain which is a cloud of points represented in blue and the free-space path loss in red line. The cloud of points is obtained by using the ray tracing data of each AP. The graph means that all points which are around the free space path loss are in LOS with the corresponding AP whereas far away points are in NLOS with the AP.

Saving the Grid File¶

This next cell is for saving the grid in a file in a proper format for being used by Pylayers coverage module.

fd = open("tc1_metis_grid.ini","w")
fd.write("[coordinates]\n")
for k in np.arange(len(df['xue'])):
    fd.write(str(k+1)+" = "+str(df['xue'][k])+" "+str(df['yue'][k])+" "+str(df['zue'][k])+'\n')
fd.close()

Simulation¶

In order to simulate with PyLayers, the following libraries are first imported.

from pylayers.antprop.coverage import *
from pylayers.gis.layout import *
from pylayers.util.project import *
from pylayers.simul.link import *
import pylayers.signal.waveform as wvf
%matplotlib inline

Reading TC1_METIS layout¶

The TC1 Metis layout has been edited with JOSM editor (Java OpenStreetMap Editor) and the edited layout is shown with the air wall as following:

L=Layout('TC1_METIS.lay')
f,a=L.showG('s',aw=1)
a.axis('on')

(-10.0, 35.0, -5.0, 20.0)

../../_images/MetisRayTracing60GHzforTC1_54_1.png

This next cell is for displaying the layout in 3D.

#ll L.show3()

Vizualisation of the Layout¶

After reading the Layout in the above figure, it can be visualized as follows:

#L.dumpr()
f=plt.figure(figsize=(30,30))
ax=f.gca()
f,ax=L.showG(f=f,ax=ax,graph='s',labels=True,font_size=18,node_size=220,node_color='c')
a=plt.axis('off')
#plt.savefig('vizualised TC1')

../../_images/MetisRayTracing60GHzforTC1_58_0.png

../../_images/MetisRayTracing60GHzforTC1_58_1.png

The visualized layout shows the numbering of segments and nodes. The nodes which have positive index are called segments (or wall) and those with negative index are the highest points (vertexes).

Displaying Subsegments of the Layout¶

f,a=L.showG('s',subseg=True,figsize=(10,10))

../../_images/MetisRayTracing60GHzforTC1_60_0.png

Building associated graphs¶

Graph of structure¶

This graph is used to describe the outline of the layout and the used materials. The graph of structure is shown here with the air wall (aw). The node is defined as a discrete position in the graph whereas the edge is the link (connection) between two vertexes that can be either direct or not.

f=plt.figure(figsize=(10,10))
a=f.gca()
f,a = L.showG('s',aw=1,fig=f,ax=a)
a.axis('off')

(-10.0, 35.0, -5.0, 20.0)

../../_images/MetisRayTracing60GHzforTC1_62_1.png

Topological graph¶

This graph contains the information about the different connections of rooms in terms of electromagnetic propagation inside the layout. In this graph the vertexes are represented by distinct points and the edges by connected pieces of arcs (also called edges) that join the corresponding pair of points.

f=plt.figure(figsize=(10,10))
a=f.gca()
f,a=L.showG('st',fig=f,ax=a,labels='t',fontsize=18,aw=1)

../../_images/MetisRayTracing60GHzforTC1_64_0.png

Visibility Graph¶

This graph describes all the possible electromagnetic paths through the layout. It is the graph of inter-visible locations for the set of points (nodes) and obstacles in the layout. Each node in the graph represents a point location, and each edge represents a visible connection between them. That means, if the line segment connecting two locations does not pass through any obstacle, an edge (connection) is drawn between them in the graph.

L.build()
f,a=L.showG('v')

../../_images/MetisRayTracing60GHzforTC1_66_0.png

Graph of interactions¶

This graph describes all the possible electromagnetic interactions between the nodes. There are three interactions type: reflection, diffraction and transmission. This graph is directly used to determine rays signatures.

f,a=L._showGi()

On the 2 figure above this is a representation of the graph of interactions with nodes corresponding to the true position on th e right and nodes position calculated from the graph topology.

Defining AP and UEs¶

The following graph shows the position of AP5 and all users equipment.

A=np.array([df['xap'].values,df['yap'].values,df['zap'].values,])
B=np.array([df['xue'].values,df['yue'].values,df['zue'].values,])

Defining a frequency range

Multi-wall Model: Motley Kennan Model¶

In the following figure we plot the radio link between C=AP5 and D.

C=np.array([12.5,6.25,2.85])
D=np.array([0.5,8.5,0.75])

# figure instanciation
f = plt.figure(figsize=(10,5))
ax = f.add_subplot(111)
r = np.array((C,D))
# plotting the Layout
f,ax = L.showG(fig=f,ax=ax,graph='s',nodes=False)
# plotting the Tx and Rx
ax.plot(C[0],C[1],'ob')
ax.plot(D[0],D[1],'or')
# plotting the LOS
ax.plot(r[:,0],r[:,1])
a = plt.axis('on')
plt.savefig('LOS AP midle one UE')

../../_images/MetisRayTracing60GHzforTC1_79_0.png

Motley Kennan model: In this model, the propagation loss is computed based on the path loss in free space added by the loss (attenuation) due to obstacles (walls, floors, or obstructions) along the direct path. This means that this model count the number of walls, floors, and other obstacles between the transmitter and the receiver to produce the propagation loss along the direct path. It does not provide any information about multi-paths but it can be still used to optimize the indoor radio network. A ray tracing approach is much more accurate for better optimization; however it is also time consuming. Thus, it is relevant to proceed with a simple and fast approach as the Motley Kennan model.

Mathematically the Motley Kennan model can be written the following expression:

\[ \begin{align}\begin{aligned} PL = 20*log_{10} {4 \pi d}{\lambda} +p*(WAF) + k*(FAF)\\where :math:`p` is the number of walls, :math:`WAF` is wall attenuation\end{aligned}\end{align} \]

factor, \(k\) is the number of floors and \(FAF\) means the floor attenuation factor.

This specific model accommodates wide range of frequencies with the appropriate choice of attenuation factors. The measured attenuation values of different materials at different frequencies can be found in the literature review.

Antenna Description¶

The antenna type that will be used to simulate the coverage Motley Kennan in the following section is an Omni-directional antenna which radiates radio wave power uniformly in all directions in a given plane. This type of antenna is best suitable for applications that require round coverage because the radiated signal has same strength in all directions. The following figure shows the polar representation of the antenna radiation pattern at 3GHz and 5.95GHz with a maximum gain of 5dB.

Polar Representation¶

A = Antenna('S1R1.vsh3')

f = plt.figure(figsize=(20,20))
a1 = f.add_subplot(121,projection='polar')
f1,a1 = A.plotG(fGHz=[3,32],plan='theta',angdeg=0,GmaxdB=5,fig=f,ax=a1,show=False)
a2 = f1.add_subplot(122,projection='polar')
f2,a2 = A.plotG(fGHz=[3,32],plan='phi',angdeg=90,GmaxdB=5,fig=f,ax=a2)
f2.tight_layout()

../../_images/MetisRayTracing60GHzforTC1_82_0.png

The above figure describes the antenna radiation pattern with vertical plane in the (left) and horizontal plane in the (right). It can be observed that the antenna radiates in all directions by concentrating the same energy equally (horizontal plane). At the same time, the vertical plane reveals that there is a back radiation because the reflector of the antenna reflects all the energy in the second half of the polar plane.
