hello my name is bill McKinley and I am
a strategic planner for keysight
technologies focused on our cellular b2x
solutions today I'm going to give you an
overview and a demonstration of our C
b2x solutions let me quickly go over the
configuration that we have today we have
our uxm 5g network emulator running
various applications that will test our
cellular v2x module the module that
we're testing today is a qualcomm
roadrunner evaluation kit what we have
also is our MXG and the MXG is our GNSS
emulator and as you know GNSS is
critical for cellular b2x testing not
only does it give geolocation but also
is used for synchronization so let me
give you a quick overview so here we
have the GNSS going into the evk and we
have the transmission for the pc five
connected to the uxm 5g what i have
running at the moment we have our cv 2x
test application here we see we have two
tabs the first tab is for our LTE
connection for mode 3 the second tab
here which we have active is our side
link tab and we can see it's highlighted
we have the site link channel on we can
see here that we are able to control and
set up the the channel as well as GNSS
and the UX and 5g controls the MXG for
genesis so we are invoking to control
right now for GNSS a couple of tabs I'd
like to show you here we're working on
the site link and we can set up what we
call our schedulers both transmission
and receive scheduler these set up the
channel parameters for allowing the
channel allocations the resource blocks
to be set for testing in a real world
environment the other graph I'm going to
show is our Blair throughput and when I
start the scenario we will see the
transmission
the packets being transmitted and
received as part of the test so what are
we gonna do here we're going to set up a
real-world scenario using an application
that we have from our partner Nord sis
let me show you it here this is our wave
be creator software and you can see we
have creates created a scenario based in
Germany and so when we run the scenario
we will see these simulated vehicles
actually in action so the other software
I'm going to show you is our wave be
touch so we once we start the scenario
we're going to see the scenario play out
in real-time in this map the third piece
of software I'm going to show is our
director application now this director
application essentially controls the
whole scenario testing it synchronizes
the scenario the GNSS and the UX m5g to
measure and to play out the scenario of
interest so what I'm going to do now I'm
going to use the director application
which is going to initiate the whole
test sequence so if I press Start we can
see the whole startup sequence
so first the director application test
the connection between the UX m5g and
the MXG GNSS scenario and the IDS tax
once it's confirmed that the connections
have been validated it loads the IDS
stack scenario now this scenario is from
the wave be Creator application we saw
before it takes the information from all
the simulated vehicles loads that
scenario in two instances of the stack
running inside the UX and 5g it then
will create on the GNSS scenario this
GNSS scenario is a dynamic scenario
taking from the maps from the creator
software the maps will generate
geolocation dynamic scenario that we
load into the GNSS emulator which will
be played out to the device on the test
so the module considers itself driving
around you
because it's going to be part of the
scenario that we created so here we've
run through I'm going to execute fine
I'll look at and wait we touch we can
see the scenario that is being playing
out let me zoom in a little bit here and
we can look in so we have a junction we
have some vehicles and at the moment two
vehicles are going to collide okay so
the scenario has then stopped we see the
vehicles that were created then the
Creator application have played that the
scenario the scenario was a crash and
the emergency vehicle came we could zoom
in and we can see the situation in the
junction where we have the crashed
vehicles and the emergency vehicle let
me zoom out again because one of the
questions that we get asked is can we
test a scenario being played out but in
a congested environment in other words a
stress test for the device because we
need to make sure the device receives
the highest priority messages in the
presence of multiple vehicles so I'm
going to then go back to my director
application and I'm going to go to the
congestion tab and I'm going to start
congestion so we're going to create 100
simulated vehicles in the area of the
scenario so I'm going to start if I go
back to my wave be touch and I expand
out we can see here's a scenario in the
center of our image but we're seeing if
we have 100 simulated vehicles all
transmitting over the pc5 link so the
test would be does my module and the
test still receive the highest priority
messages in the presence of all these
other vehicles finally let me go back to
my test application and I'm going to
look at the Blair throughput from our
transmissions so if I'm going to go
local here I'm going to start the
the measurement so when I start this
Blair measurement here I can see
transmissions from the scenario if I go
back to my my so now I'm going to start
congestion what we should see is the
transmissions from the congested
vehicles that we can see over the PC
five lengths the packets that are being
created
looking at these congested vehicles so
this gives you some idea of the
flexibility we have of our test solution
we can create scenarios we can download
these scenarios into our UX and 5g GNSS
emulator we can test our vehicle
receives and reacts appropriately to
highest priority messages then we can
add in congestion we can carry out those
same tests in a congested environment to
make sure that your module truly is
ready for the market thank you very much
