Foreword

• Mobile healthcare is becoming a hot spot in hospital informatization construction. It enables

hospitals to break away from the traditional wired application mode and enter the new

wireless and mobile application mode. WiFi networks are usually the necessary basis for

carrying mobile healthcare services.

• Medical IoT greatly improves medical efficiency with its applications in asset management,

infant anti-theft, mobile clinical, transfusion monitoring, and personnel positioning. The

combination of IoT and Wi-Fi network construction has become the mainstream trend of

hospital informatization construction.

• This document describes Huawei's Wi-Fi 6 and IoT co-deployment solution in healthcare

scenarios, and describes the principles and precautions for network planning and design in this

scenario.

Healthcare Scenario Overview

ward consultation room

• Space: The structure is complex, and the wall structure varies greatly in different functional areas. Most of

the walls are common floor height scenarios. The floor height of the hall area may exceed 6 m.

• Roaming: Medical staff must ensure that services are not interrupted, information is not lost, and the

working experience of medical staff

• Networking: The hospital wireless network is usually divided into internal and external networks. The

internal network is mainly used by medical personnel, and the external network is used by patients and

family members.

Challenges in Healthcare Scenarios

Configuration management based on a single AP, with multiple management

nodes

Dense small rooms

There are many small rooms, complex wall structure, and large wall penetration loss

High roaming requirements

Medical devices are sensitive to in-roaming packet loss. Therefore, the packet loss rate must be low.

MIMOThe 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. Select APs with proper antenna gains based on site requirements.

Power supplyThe 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 standardThe 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 featuresAs 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.

AP Deployment Rules

1. When installing an AP, try to reduce the number of obstacles through which signals pass.2. Ensure that the front side of an AP faces the target coverage area and the AP is far away from interference sources.3. If PoE power supply is required, it is recommended that the distance between the AP deployment position and ELV rooms (where PoE power

sources are located) be less than 100 m.

Application Scenarios and Coverage Key Messages of Common APs

• Omnidirectional AP

▫ The AP can be installed on the ceiling (recommended, with the top height not exceeding 6 m) or on the wall (about 3 m).

▫ The medical scenario is an indoor semi-open scenario. Considering the edge scenario –65 dBm, the maximum coverage

distance of 2.4 GHz is 35 m, and the maximum coverage distance of 5 GHz is 15 m.

▫ Factors such as obstacles and the number of access terminals must be considered for site deployment in each sub-scenario.

For details about the deployment distance, see the network construction standards in the next section.

▫ When the AP is installed on a wall, the signals on the back of the AP are blocked by the bearing column or wall.

• Panel AP/sensitive RU

▫ Mainly used in ward, consultation room and other solid wall partition independent small rooms.




Common Services and Average Bandwidth in Healthcare Scenarios

If the bandwidth requirement in a specific scenario is not specified, evaluate the required bandwidth based on the table above.The average bandwidth required in different scenarios is the sum of the single-service baseline rates of different service types multiplied

5 16 Mbps 12 18 30

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.

Number of Concurrent STAs Supported by a Single AP (1/2)

The preceding table lists the specifications of an AP (Wi-Fi 6, 4x4, HE40).

The WLAN physical rate refers to the PHY rate 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 the PHY rate because the actual rate at the application layer is calculated by subtracting various overheads from the air interface rate.

2. APs and RFIDs are deployed at the same site.

• Wards, consultation rooms, offices, conference rooms, waiting areas, infusion areas, corridors,

nurse stations.

3. Special scenarios:

• Hall: If the floor height is more than 5 meters, it is recommended to install it on a hanging pole

or wall. The installation height is less than 5 meters.

4. Note:

• Interface: There are two types of IoT cards: PCIE card and USB card. Panel APs and RUs such as

ward/diagnosis only support USB card form. Panel APs can be selected based on the panel form.

• WIFI and non-positioning RFID signals can penetrate foam board, gypsum board, 120 mm thin

brick wall covering, after passing through can cover 5-10 meters.

Guide to Network Construction for Medical IoT Personnel Positioning Services

Personnel Positioning Service Network Construction Guide

• Deployment policy: The distance between APs is based on the standard deployment of each sub-scenario. Independent IoT locator base

stations are deployed between APs based on precision requirements and environment requirements.

• Maximum installation height of the AP and base station: 5 m

• It is recommended that signals of IoT base stations (125khz) not be covered by walls, which affects the positioning accuracy.

1 2 3 4

The positioning radius of the USB and PCI-E IoT base station (125khz) is adjustable from 1 to 3 meters. The positioning radius of the stand-alone POE-powered base station is from 1 to 4 meters. The base station connected by the tag or terminal is located under this base station. Therefore, the posi tioning precision of the integrated module is from 2 to

6 meters. Standalone base station 2 - 8 m.

• To improve the positioning accuracy, shorten the distance between BTSs, increase the number of BTSs, and set a shorter

positioning radius.

• The AP and base station must be installed at a height of no more than 5 m, and at least 3 m away from the bearing pole.

AP Position Planning

• General principle: APs are installed on ceilings and far away from load-bearing columns. A single AP in a room is installed in the middle of the target coverage area.

• Automatic deployment is recommended. Automatic deployment has the same effect as manual deployment.

In the hall, there is an atrium structure in the middle of the dotted line, and the ceiling height is 8 m. Therefore, APs are deployed at the

common floor height outside the green dotted lines at spacing of 18 m.

The infusion area is 15 m long and 10 m wide, and only one AP is required.

The office and duty rooms are small. The agile distributed RUs and central AP are deployed to reduce costs and provide good coverage. RUs in the office and duty rooms can connect to the same central AP for RUs in the consultation room.

The consultation room is small. Therefore, agile distributed RUs and central APs are deployed to reduce costs and provide good coverage.

The medicine taking area is 20 m long and 6 m wide, and only one AP is required.

One AP is deployed in the nurse station to also cover the corridor.
