Foreword

⚫ Evolving information technologies have made life easier and transformed the way education is
delivered — boring textbooks replaced by multimedia teaching aids, and heavy schoolbags replaced by
thin, electronic ones. All these changes require the support of a mature and stable network.

⚫ Typical education scenarios include classrooms, auditoriums, libraries, and labs, where students are
densely distributed. Such a scenario is usually characterized by high user density, a large number of
concurrent users, a high volume of burst traffic, and sensitivity to network quality.

⚫ Wi-Fi 7 supports the 6 GHz frequency band and introduces technologies such as 320 MHz bandwidth
and 4096-QAM, increasing the maximum transmission rate by 2.4 times than Wi-Fi 6. Additionally,
innovative multi-RU technology further improves the air interface efficiency, easily meeting the
requirements of high bandwidth and high concurrency in education scenarios.

⚫ This document describes the WLAN planning and design process in education scenarios and Huawei's
recommended WLAN construction standards for typical education sub-scenarios.

(Mobile phone hotspot) Method

1. Place the signal source. Ensure that no blocking is in between the signal
source and the obstacle to be tested and the distance between them is 4 m to 5
m. Ensure that the position of the signal source is unchanged during the test.
Note: The phone hotspot needs to be configured to support the 2.4 GHz, 5 GHz, and
6 GHz frequency bands respectively.
2. Test the signal field strengths at test points 1 and 2, as shown in the figure.
You are advised to use the Wi-Fi status function of the CloudCampus APP. The
duration of at least 60s is recommended for each single test, and the average
values of all tests is used.
Note: During the test, it is recommended that the test phone be placed at the same
height and in the same direction at test points 1 and 2.
3. Attenuation calculation method: Signal attenuation of the obstacle to be
tested = Field strength tested at test point 1 – Field strength tested at test point 2
Note: The attenuation values of the 2.4 GHz, 5 GHz, and 6 GHz frequency bands need
to be tested separately.

The signal attenuation caused by the metal mesh (grid) material is related to the grid size. In most cases, when the diameter of a grid is greater than the
half wavelength of wireless signals, signals can penetrate the grid but are still attenuated. In actual projects, it is recommended that you test the
attenuation values onsite.
Note: Wavelength (m) = Speed of light (m/s)/Frequency (Hz). (Typical half wavelength: 6.3 cm @ 2.4 GHz; 2.9 cm @ 5.1 GHz; 2.5 cm @ 6 GHz)

Improper location: Signals penetrate several walls. Proper location: Signals penetrate only one wall.

1. Install common settled APs on ceilings (recommended) or walls, at a height of no more than 6 m. When an AP is installed on a wall, assume that
signals at the rear of the AP are completely blocked by a load-bearing pillar or wall.
2. Wall plate APs can be installed on walls, desks, or ceilings or in junction boxes (86 mm). Select an installation mode based on project requirements.
3. Minimize wall penetration of AP signals. Generally, it is recommended that signals pass through only a single-layer wall (120 mm brick wall). In
some special scenarios (such as gypsum walls and glass walls), signals can pass through two walls.
4. It is recommended that signals not pass through 240 mm thick brick walls, concrete walls, or metal walls. If the AP penetration coverage solution is
used without meeting the specified constraints, signals become weak after passing through a wall. In this case, to ensure good coverage and user
experience, deploy more APs based on the wall structure.
5. Deploy APs separately in key areas and VIP areas to ensure good user experience.
6. Deploy APs separately at intersections or corners to ensure signal coverage continuity (> –65 dBm) and that neighboring APs can establish neighbor
relationship tables for good roaming experience.
7. Install APs at least 3 m away from load-bearing pillars.
8. In high-ceiling scenarios (height > 6 m), such as auditoriums and lecture halls, APs with directional antennas (70°) can be ceiling mounted or wall
mounted on both sides.

1. APs can be installed on poles or walls. It is recommended that APs and antennas be installed at a height of 3–5 m.
2. Typical coverage range (typical EIRP limits: 20 dBm @ 2.4 GHz, 30 dBm @ 5 GHz, and 14 dBm @ 6 GHz):
Outdoor APs with omnidirectional antennas are recommended for open areas such as parks and intersections. The recommended coverage radius is 60–80 m.
Outdoor APs with built-in directional antennas are recommended for campus roads and playgrounds. The recommended coverage range is 80–100 m, and the recommended
coverage width is 30–40 m.
3. Typical coverage range (the AP is configured with the maximum transmit power):
Outdoor APs with omnidirectional antennas are recommended for open areas such as parks and intersections. It is recommended that the maximum coverage radius be 150 m.
Outdoor APs with built-in directional antennas are recommended for campus roads and playgrounds. It is recommended that the maximum coverage range and width be 200
m and 100 m, respectively.
4. Ensure that outdoor sites are not blocked by trees or buildings. Try to reduce the number of obstacles that signals pass through.
5. It is recommended that outdoor APs cover only outdoor scenarios, but not both indoor and outdoor scenarios.
6. Generally, in outdoor scenarios, the EIRP limit is 14 dBm on the 6 GHz frequency band, and the coverage range is only 10–15 m. It is recommended that the 2.4 GHz and 5 GHz
frequency bands be used for common outdoor coverage, and the 6 GHz frequency band be used only for short-range coverage or outdoor high-density scenarios.
7. The coverage range varies depending on the EIRP limit, AP model, and antenna model. For details about the coverage ranges supported by AP and antenna models, see
the scenario-based WLAN design for outdoor scenarios or use the WLAN Planner for simulation.

For example, a large conference room has 200 seats. Assuming the concurrency rate of 30% and the per-STA
bandwidth of 6 Mbps, the concurrent bandwidth required by 60 STAs is 6 Mbps. Note: It is recommended that the

one AP can support concurrent 6 Mbps for 83 (32 + 51) STAs. In this case, only one AP is required.

The device rates in the product data sheets are the maximum theoretical PHY rates calculated based on the maximum channel bandwidth and the maximum number of spatial streams. The
access bandwidth values in the tables above are the rates at the application layer calculated based on the typical channel bandwidth (20 MHz @ 2.4 GHz, 40 MHz @ 5 GHz, and 80 MHz @ 6
GHz) and dual spatial streams (STA capability restriction). Specifically, the rates at the application layer are calculated by subtracting various overheads including multi-user concurrency
overheads from the air interface rates. Therefore, the concurrent rates of APs in actual application scenarios are much lower than device rates.
Currently, STAs tend to connect to a 6 GHz radio (80 MHz) rather than a 5 GHz radio (40 MHz). When the actual number of concurrent STAs exceeds the recommended value of the 6 GHz
radio, you need to configure the maximum number of associated STAs on the 6 GHz radio.

User-perceived rate: target rate that can be achieved in 95% of areas according to SpeedTest on a light-loaded network where the channel
utilization is less than 20%. The rate is typically considered as the peak rate.
Service-assured rate: target rate that can be achieved in 90% of time according to SpeedTest in a multi-user concurrency scenario where the
network load is less than 80%. The rate is typically considered as the guaranteed rate.
Lecture hall Co-channel interference channel: channels operate on the same frequency and have an RSSI of greater than or equal to –85 dBm.
Currently, STAs tend to connect to a 6 GHz radio (80 MHz) rather than a 5 GHz radio (40 MHz). When the actual number of concurrent STAs
exceeds the recommended value of the 6 GHz radio, you need to configure the maximum number of associated STAs on the 6 GHz radio.

Bandwidth Design Example for High-Density
Stadiums
• In high-density scenarios, APs are densely deployed in open areas without obstacles. Even if directional antennas are used to reduce
interference, co-channel interference between APs, between APs and STAs, and between STAs cannot be completely avoided, and co-
channel APs cannot perform service concurrently. Therefore, the multiplexing coefficient is introduced. The multiplexing coefficient is
related to AP models, deployment modes, and available channels, and needs to be comprehensively evaluated.
• The following lists the recommended channel configurations in high-density scenarios. Considering factors such as service diversity,
STA differences, and channel interference, it is estimated that the actual throughput of a single 20 MHz channel is 50 Mbps.
• Number of access users: number of mobile phones associated with the Wi-Fi network. Based on the indoor stadium project delivery
experience, the access rate is usually 40% of the number of seats in the stadium.
Total peak egress bandwidth = Number of available channels x Multiplexing coefficient x Actual throughput of a single channel
Single-user experience bandwidth = Total peak egress bandwidth/(Number of access users x Concurrency rate)

Deploy one AP in
a small or midsize
classroom, and
two APs in a large
lecture hall. Deploy one wall plate AP
in each teacher lounge,
which has a small area
and low concurrency rate.


In corridors with low requirements on
concurrency and bandwidth, deploy APs at a
spacing of 25 m to 35 m. To ensure the roaming
effect, deploy APs at intersections and corners.
Ensure that elevator halls and lounges connected
to the corridors also have signal coverage.
