Foreword
•The enterprise office scenario refers to the office area of an enterprise, including the centralized office
area, conference room, and manager office. It is one of the most important application scenarios of the
enterprise WLAN. The user density in the enterprise office scenario is high. Therefore, this scenario has
a high requirement for network capacity and is sensitive to network quality.
•With the rapid increase in the number of user terminals and the popularity of Wi-Fi terminal access,
the enterprise office scenario poses a high requirement for concurrent access to the Wi-Fi network,
especially in large conference rooms and densely populated office areas. Traditional solutions cannot
meet this requirement.
•This design guide describes the service characteristics and WLAN requirements of enterprise office
scenarios, as well as methods, principles, and precautions for the solution high-level design (HLD) in
these scenarios.

Enterprise Office Scenario Overview
•Space: In most cases, the height does not exceed 4 m. The specific areas range from several square meters to thousands of
square meters.
•Obstacle: Obstacles are common in offices, including cubicles and support pillars in large offices. These obstacles block
signals to some extent.
•Interference: There are seldom external interference sources in independent office areas. However, if several companies
lease offices on the same floor, the WLANs of the companies may be severely interfered.
•Capacity: Office scenarios have high requirements on bandwidth. Different enterprises have different standards. Some
enterprises use all-wireless office, and others use wired+wirelessoffice.

Device Model Selection Factors
MIMO
The number of spatial streams ranges from 4 to 16. An AP with more spatial streams supports higher throughput and
larger access capacity. Therefore, select APs with a proper number of spatial streams based on the application scenario
and access density.
Antenna
Indoor APs support omnidirectional, directional, and smart antennas. Outdoor APs support omnidirectional and
directional antennas.
Indoor scenario: Smart antennas provide the best coverage effect. Therefore, APs with smart antennas are
recommended. Directional antennas are suitable for high installation scenarios. Omnidirectional antennas are suitable
for scenarios where the coverage area is small and the deployment is not dense.
Maximum transmit power
(combined power)
The Wi-Fi transmit power is controlled by the country code and varies depending on the local regulations. When the
transmit power gets closer to the specified upper limit, the transmitted signal is stronger and the coverage distance is
longer. For details, see the Country Codes and Channels Compliance in the product documentation.
Antenna gain
A higher antenna gain indicates a stronger signal strength and longer coverage distance. SelectAPs with proper
antenna gains based on site requirements.
Power supply
The power supply mode is related to the deployment scenario. Currently, PoE power supply is used in most scenarios.
You can also use a power supply or use dual power supplies for backup. Pay attention to the AP's power consumption
and the power supply capability of PoE switches.
Wi-Fi standard
The Wi-Fi standard has evolved to the sixth generation, and each generation of the standard is compatible with earlier
ones. The latest Wi-Fi 6 standard greatly improves the Wi-Fi speed and capacity, and achieves a four-fold increase in the
throughput and capacity. Therefore, Wi-Fi 6 APs are recommended.
Other features
As the Internet of Things (IoT) comes into widespread use, deploying an IoT network independently will cause repeated
cabling, separate management and O&M, and high hardware and O&M investment. Therefore, it is recommended that
IoT scalability be considered when you select Wi-Fi APs.

1.When installing an AP, try to reduce the number of obstacles that signals traverse. It is recommended that signals pass through a single-layer wall (typically 120 mm brick
wall). In some special scenarios (such as gypsum walls and glass walls), signals pass through two-layer walls.
2.Penetration coverage is not recommended for 240 mm thick brick walls, concrete walls, and metal walls. If AP penetration coverage is still used when constraints are not
met, weak signals and discontinuous roaming may occur after wall penetration. In this case, ensure good coverage and roaming.APs need to be deployed based on the
customer's wall structure.
3.Deploy APs independently in key areas and VIP areas to ensure user experience.
4.Independent APs are deployed at intersections or corners to ensure signal coverage continuity (greater than –65 dBm). Neighbor relationship tables can be set up between
adjacent APs to ensure good roaming experience.
5.The AP is installed at least 3 m away from the bearing column.

Application Scenarios and Coverage
Specifications of Common APs
•Omnidirectional antenna AP
▫The AP can be installed on a ceiling (recommended, with the top height of no more than 6 m) or on a wall (with the
height of about 3 m).
▫Indoor office is a semi-open scenario. Considering the edge scenario of –65 dBm, the maximum 2.4 GHz coverage is 35 m,
and the maximum 5 GHz coverage is 15 m.
▫For site deployment in each sub-scenario, factors such as obstacles and the number of access terminals must be considered.
For details about the deployment distance, see the network construction standards in the next chapter.
▫When the AP is installed on a wall, all signals at the rear of the AP are blocked by the bearing column or the wall.
•External directional antenna AP（AirEngine6760-X1E/ AirEngine6761-21E ）
▫It is mainly used in high-height scenarios such as exhibition halls. It is recommended that APs and antennas be installed on
the ceiling at a height of 6 m to 12 m.
▫The 70°directional antenna 27013720 is recommended. It’s recommended to be deployed at an equal spacing of 18 m to
20 m.

The number of concurrent STAs supported by an AP is used to calculate the number of APs required
to meet the capacity requirement while meeting the coverage requirement.
For example, 200 STAs are connected to the network, with the concurrency rate of 30%. That is, only 60 STAs run services concurrently. When
both APs and STAs comply with Wi-Fi 6, a single STA requires 8 Mbps bandwidth and a dual-band AP (4x4 MIMO) supports concurrent access of
30 STAs (2x2 MIMO). Therefore, two APs are required to meet the capacity requirement.

The preceding table lists the specifications of an AP (Wi-Fi 6, 4x4 MIMO, HE40). For details
about other specifications, see the WLANPlanning Specifications.
The WLANphysical rate refers to the PHYrate of the air interface, that is, the rate that can be reached by the physical layer of the air interface.
The PHY rate is described in the product documentation.
The rate in the preceding table is the rate at the application layer. The actual rate at the application layer is lower than thePHY rate because the
actual rate at the application layer is calculated by subtracting various overheads from the air interface rate.

•AP deployment in W-shaped mode
•AP spacing of 10–12 m
•As Few 2.4 GHz channels are available. We
need to disable some 2.4 GHz radios to
reduce co-channel interference.
•Due to hardware constraints, the distance
between APs using omnidirectional antennas
cannot be less than 6 m. Otherwise,
adjacent-channel interference may occur,
affecting throughput.

and deployment
•Use the omnidirectional AP Installed on a T-
rail.
•Refer to the points in the figure for AP
positions.
•AP deployment in W-shaped mode
•AP spacing of 15–18 m
•As Few 2.4 GHz channels are available. We
need to disable some 2.4 GHz radios to
reduce co-channel interference.
•Due to hardware constraints, the distance
between APs using omnidirectional antennas
cannot be less than 6 m. Otherwise,
adjacent-channel interference may occur,
affecting throughput.

Suggestions for network planning and deployment
•Mount APs with omnidirectional antennas on T-rails for coverage.
•Refer to the blue points in the preceding figure for AP positions. For areas that have requirements on appearance, select thecorresponding
landscaping mode for installation.
•The wall between adjacent washrooms is thick. Therefore, wall penetration coverage is not recommended. Deploy an AP in each washroom.

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:
Concurrency = 300 x 2 x 40% =
240
An AirEngine 5760-51 (2.4G @
HE20; 5G @ HE40) can
support 30 concurrent STAs at
average bandwidth of 8 Mbps.
A total of eight APs are
required (240/30=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: Install APs on T-rails 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.
