Foreword
⚫The enterprise office scenario is one of the most important application scenarios of the enterprise
WLAN. With the rapid increase in the number of user terminals, Wi-Fi terminal access is becoming
popular, and more and more services require high bandwidth. As such, higher requirements are
imposed on concurrent access to the Wi-Fi network in enterprise office scenarios, especially in
conference rooms and densely populated office areas.
⚫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 addressing the
requirements of high bandwidth and high concurrency in office scenarios.
⚫This design guide describes the WLAN planning and design process in enterprise office scenarios, as
well as Huawei's recommended network construction standards for typical enterprise office
subscenarios.

Enterprise Office Scenario Overview
•Space: In most cases, the height does not exceed 4 m. Obstacles are common in offices, including partition walls and
load-bearing columns.
•User density: The typical user density is one user per 4–5 square meters, which varies in different enterprises.
•Services: Typical services include office and personal services. Most enterprises use wired + wireless office, while
others use all-wireless office.

Testing the Signal Attenuation Caused by Obstacles
Onsite (Example)
Purpose
Test the obstacles on site to obtain the actual signal attenuation values, which
provide accurate input for subsequent network planning.
Object
Typical indoor obstacles or obstacles with uncertain materials (such as a decorative
wall).
Method
1.Signal source placement: 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. Signal field strength test: Test the signal field strength at test points 1 and 2, as
shown in the figure. You are advised to use the Wi-Fi status function of the
CloudCampusAPP.
Note: It is recommended that the phones at test points 1 and 2 be placed at the same
height and in the same direction.
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 following table lists signal attenuation caused by common obstacles.
The signal attenuation caused by the metal mesh (grid) material is related to the grid size. In most cases, when the diameterofa 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 @ 2.4G; 2.9 cm @ 5.1G; 2.5 cm @ 6G)

1.APs can be mounted on ceilings (recommended) or walls, at a height of no more than 6 m. When an AP installed on a wall, assume that signals at the rear
of the AP are completely blocked by a load-bearing pillar or wall.
2.Minimize wall penetration of AP signals. Generally, it is recommended that signals pass through a single-layer wall (120 mm brick wall). In some special
scenarios (such as gypsum walls and glass walls), signals can pass through two layers of walls.
3.It is not recommended that signals penetrate a 240 mm thick brick wall, concrete wall, or metal wall. If the AP penetration coverage solution is used
without meeting the specified constraints, weak signals and discontinuous roaming may occur after signals penetrate the wall.Inthis case, to ensure good
coverage and roaming, add APs based on the wall structure.
4.Deploy APs separately in key areas and VIP areas to ensure user experience.
5.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.
6.Install APs at least 3 m away from load-bearing pillars.

Capacity Design for Enterprise Office Scenarios
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 (2.4 GHz @ 20 MHz,5GHz @ 40 MHz, 6 G @ 80 MHz) 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.
•Capacity design is to calculate the number of APs required to meet concurrent bandwidth requirements while meeting coverage requirements.
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 for 60 STAs is 6 Mbps.
When both APs and STAs support Wi-Fi 6, one AP can support 26 concurrent STAs at 6 Mbps. Therefore, three APs need to be
deployed to meet capacity requirements.
When both APs and STAs support Wi-Fi 7 and the 6 GHz frequency band is supported in the local country or regions, one AP can support concurrent 6 Mbps for 83 (32 + 51)
STAs. In this case, only one AP is required.
For more performance specifications, see WLAN AP V200R023C10 Network Planning Key Messages.

•Ceiling mount indoor APs with built-in smart antennas.
•For details, see the blue AP positions in the figure above. In scenarios with aesthetic requirements, take corresponding aesthetic
measures for AP installation.
•The walls between adjacent restrooms are thick. Therefore, it is not recommended that signals penetrate such walls. As such,
deploy one AP in each restroom.

AP Position Planning
Exhibition hall (floor height: 8 m):
Deploy APs with 70°directional
antennas providing vertical
downward coverage in W-shaped
mode at a spacing of 15 m.
Washroom: Deploy one AP
in each washroom.
Office area:
Number of concurrent STAs =
350 x 2 x 30% = 210
A 2+2+4 Wi-Fi 7 AP (5G @ 40
MHz; 6G @ 80 MHz) can
support 27 concurrent STAs at
average bandwidth of 30
Mbit/s.
A total of seven APs are
required (210/30 = 8).
Deploy APs in W-shaped mode
at a spacing of 15 m, meeting
the coverage and capacity
requirements.
Canteen: Deploy APs in a
similar way as that in the
office area.
•Overall principle: Ceiling mount APs away from columns. In a room, mount an AP in the middle of the target coverage area.
Coffee shop: It has an area of 20
m x 10 m, and one AP can meet
coverage requirements.
Office room/meeting room:
Deploy one AP to cover a room
with an area of less than 120 m
2
.
Corridor: Deploy APs at a spacing of 25 m.
To ensure roaming effect, deploy APs at
corners and intersections.

After the deployment is complete, you can check the simulation effect diagram on the WLAN Planner.
The signal coverage displayed in the effect diagram must meet the customer's signal coverage requirements.

C. Wood (40 mm)
D. Asbestos (8 mm)
2.A company wants to purchase Huawei WLAN products to provide wireless coverage for 600 employees in the
office areas to facilitate office work. Huawei's pre-sales network planning personnel need to estimate the
number of APs required for the company. According to the company's requirements, the per-STA bandwidth is
no lower than 30 Mbps, with concurrency rate of 50%. The company plans to use 2+2+4 Wi-Fi 7 APs (2.4 GHz @
20 MHz, 5 GHz @ 40 MHz, 6 GHz @ 80 MHz). Without taking subsequent redundancy into account, how many
APs are required? ( )
