Test Environment

This clause describes the performance test environment, which includes test configuration, test setup characteristics, anddevice settings.
Root node, first stage leaf node, and second stage leaf node constitute a multi AP application scenario. The root nodeconnects to the broadband network. The first stage leaf node and the second stage leaf node connect to the root node,and to each other, via wireless or wired backhaul channels (Optical fibre/Ethernet networking). The roaming STA isable to connect to any of the nodes (root, first leaf, or second leaf) via a wireless access channel.
Under the test environment, the traffic generator/analyser simulates the broadband network and multiple terminals.
Figure 1 presents a schematic diagram of the test environment for two stage networking throughput performance.
If using iPerf3 to generate the traffic, the parallel parameter instructs iPerf3 to run ten measurement streams at the sametime between the APs and STAs. This improves the overall accuracy of the measurement.

Figure 1: Test Environment for multiple access point performance testingA brief overview of this configuration follows:
1)

There are three (3) RF chambers labelled "Root", "Leaf_1", and "Leaf_2" which hold the three nodes of themultiple access point system under test. These are the Root device (which in a deployment would have thegateway connection to the wider world, for example the Internet), and the two leaf or extender devices (which
in a deployment would provide connections back to the Root).

2)

The multiple AP devices (root and leaves) are connected to each other using three (3) programmableattenuators A, B, and C. These are the "backhaul" attenuators, and for a static mesh (in which the root and leaf
nodes do not move relative to each other) those attenuations would typically not change for the duration of asingle test. Changing these attenuators changes the relative "distances" between the mesh nodes, hence, itchanges the topology of the mesh system under test.

3)

There is one (1) RF chamber labelled "Roaming STA" which holds the STA device used to test the multiple
AP system under test. This chamber is connected to each of the mesh nodes via a programmable attenuator.
Attenuator "S2R", for example, connects the STA to the Root. Attenuators S2R, S2L1, and S2L2 connect theroaming STA to the mesh nodes, and the settings on these attenuators define how "close" the roaming STA is
to each mesh node. These attenuators will change during any test in which roaming is being simulated.

ETSI

10

4)

ETSI TS 103 754 V1.1.1 (2022-06)

There is one (1) RF chamber labelled "Traffic STAs", which holds STAs (or devices that can generate virtual
STAs) used to create load on each of the mesh nodes. A set of STAs (or virtual STAs) is connected directlyfrom this chamber to one of the mesh nodes; that is, the devices in the "Traffic STAs" chamber are notexpected to participate in roaming across the mesh nodes. They are used only to generate static load on thenodes in the mesh. These traffic STAs are connected to the chambers through the attenuators S2R', S2L1', andS2L2', but these attenuators do not necessarily need to have programmability. Static attenuation may be
acceptable for these connections.

Important notes about the design shown in Figure 1:
1)

This figure is not intended to require a specific testbed configuration to be used for testing compliant with thepresent document.

2)

Any testbed that can support the tests as designed may be used for testing.

How to understand the purpose of the diagram shown in Figure 1:
1)

Figure 1 represents a design to be used throughout the present document.

2)

A single diagram used to illustrate each test case makes it easier for readers to understand the tests. Readers do
not have to adapt to a new diagram for each test.

3)

The diagram is intended to act as a guide for testers intending to create tests compliant with the present
document.That is, although this specific testbed configuration is not a requirement, it is an example
configuration that can be used as a starting point.

4)

The diagram acts as a guide for the consideration of new tests which may be proposed as an addition to thepresent document.

This is not to imply that the diagram should act as a limit to the proposal of new tests. It is to suggest, however, that due
considering should be given to the practicality of the tests.

6.1.1.4

ETSI TS 103 754 V1.1.1 (2022-06)

Procedures

Place the root and leaf_1 nodes and STAs in three shielding boxes. The root node and the leaf_1 node can be connectedin the following ways:
1)

Wi-Fi wireless networking.

2)

Set the STA support IEEE 802.11k [i.3] and IEEE 802.11v [i.4] roaming functions.

3)

In wireless networking, set the initial attenuation of A (between Root node and Leaf_1 node): 30 dB at
2,4 GHz band, 30 dB at 5 GHz band, to ensure that the RSSI range is between -60 dBm and -70 dBm.

4)

Set the STA to connect to the root node.

5)

Use the traffic generator to send 1 460 B UDP packets to the STA with 1 000 PPS. With 1 dB/s frequency,
increase the attenuation (S2R) until the attenuation from the STA to root node reaches 40 dB, and decrease theattenuation (S2L1) from the STA to the leaf_1 node until it reaches 0 dB. Then calculate the number of lost
packets, the roaming time is lost packets/packet rate.

6)

Wait for 1 min, with 1 dB/s frequency, decrease the attenuation (S2R) from the STA to the root node until theattenuation from the STA to the root node reaches 0 dB, and increase the attenuation (S2L1) from the STA tothe Leaf_1 node until it reaches 40 dB. Then calculate the number of lost packets, the roaming time is lost
packets/packet rate.

7)

Change the attenuation frequency to 2 dB/s and 3 dB/s, and repeat steps 5 and 6.

8)

Replace the STA with one STA that does not support IEEE 802.11k [i.3] and IEEE 802.11v [i.4] roaming
functions, and repeat steps 3 to 7.

In Figure 14, Leaf_1 is First stage node, Leaf_2 is Second stage node.
Root node, Leaf_1 node and Leaf_2 node are deployed in shielding box 3, the test controller and the traffic
generator/analyser can be placed outside the shielding boxes.
Four 2,4 GHz single-band terminals (Traffic STA1~ STA4), while four 2,4 GHz/5 GHz dual-band terminals (Traffic
STA5~ STA8).
Four 2,4 GHz single-band terminals (Traffic STA9~ STA12), while four 2,4 GHz/5 GHz dual-band terminals (Traffic
STA13~ STA16).
Four 2,4 GHz single-band terminals (Traffic STA17~ STA20), while four 2,4 GHz/5 GHz dual-band terminals (Traffic
STA21~ STA24).

Root node and Traffic STA1~ STA8 are configured with the same SSID; Leaf_1 and Traffic STA9~ STA16 are
configured with the same SSID; Leaf_2 node and Traffic STA17~ STA24 are configured with the same SSID.
Root node is connected to the traffic generator/analyser by network cable. Leaf_1 node accessed to Root node by
wireless as the backhaul channel of Leaf_1 node, Leaf_1 node and Root node are configured with the same SSID;
Leaf_2 node accessed to Leaf_1 node by wireless as the backhaul channel of the Leaf_2 node, Leaf_2 node and Leaf_1
node are configured with the same SSID.

Procedures

1)Band steering for Root node, Leaf_1 node and Leaf_2 node respectively, namely, dual-band terminals are
preferentially accessed to 5 GHz band.

2)

Four 2,4 GHz single-band terminals STA1~ STA4, and four 2,4 GHz/5 GHz dual-band terminals
STA5~ STA8 are connected to Root node respectively.

3)

Four 2,4 GHz single-band terminals STA9~ STA12, and four 2,4 GHz/5 GHz dual-band terminals
STA13~ STA16 are connected to Leaf_1 node respectively.

4)

Four 2,4 GHz single-band terminals STA17~ STA20, and four 2,4 GHz/5 GHz dual-band terminals
STA21~ STA24 are connected to Leaf_2 node respectively.

NOTE:

6.4.5

The band steering tests on each node may be performed simultaneously or separately.

Metrics

Record the frequency band associated with the STA and check the corresponding band column in Table 24.

Annex A (informative):
Link Budget
Figure A.1 shows the link budget for the attenuations.
There is OTA loss in each box, and insertion loss for the attenuator. In this test case, the OTA loss is 25 dB, andinsertion loss is 10 dB.
