2.4 Architecture of the TM80 Telemetry Monitoring System
The following figure illustrates the physical units of the TM80 Telemetry Monitoring
System. It shows how these devices and functional units are interconnected to form
a complete telemetry monitoring system.
The TM80 Telemetry Monitors are worn on patients. As shown in the figure above,
patients’ physiological information collected by the TM80 Telemetry Monitors is
transmitted through the low power consumption Wi-Fi modules built in the
telemetry monitors. Wireless signals are acquired by AP arrays and then are
transmitted to the CMS through the existing network system of the hospital. On the
CMS, the information is displayed, stored and processed based on a certain
algorithm and alarms are generated. In addition, patients can seek for help from
nurses on the CMS side by using the nurse call function. When a TM80 Telemetry
Monitor is connected to the CMS, doctors can view its patient information in the
ViewBed window of the CMS.

3 Installation
3.1 Overview
3.1.1 Introduction
TheTM80 Telemetry Monitor (hereinafter called TM80) exchanges data with the CMS
via Wi-Fi network. Wi-Fi communication is the core function of the TM80. This
chapter guides users to use the Wi-Fi communication function properly and reliably.
WARNING
To ensure reliable operation of the TM80 wireless network, deploy the
network in strict accordance with relevant requirements in this manual and
keep maintaining the network properly after installingthe TM80. If the
network is not deployed according to this manual, data transmission of the
TM80 may be delayed, or even be lost, thus resulting in clinical risks.
CAUTION
Customers are responsible for network management. Changing network
after installation may deteriorate the performance of the TM80.
Therefore, customers need to sufficiently assess network change so as to
avoid impact on clinical use of the TM80.
BeneVision TM80 Telemetry Monitor Service Manual 3-1
Page 24
3.1.2 Business Types
The WLAN deployment requires certain techniques and accumulation of experience.
On the market, professional communication technical service companies such as
local agents of Cisco implement the engineering in most cases. Mindray
recommends hospitals to choose the third-party engineering deployment agencies
to complete network environment deployment in preference.
Three processing modes are provided for different circumstances:
The hospital has built its WLAN: Mindray defines specification requirements and
acceptance methods, inspects the hospital by sending field engineers to the
hospital and confirms the requirements on site. If the hospital’s network
cannot meet deployment requirements of the TM80, Mindray informs the
hospital of possible consequences such as disconnection and requires the
hospital to rectify the WLAN according to requirements of Mindray.
The hospital builds a new WLAN to cover areas greater than 2000 square meters
for the TM80, and IT requirements are complex: Mindray recommends that a
third-party construction organization carries out construction and completely
uses the network devices and configurations developed and verified by
Mindray. Mindray defines specification requirements and acceptance methods,
inspects the hospital by sending field engineers to the hospital and confirms
the requirements on site after the construction organization completes
confirmation. The third-party construction organization must have: documents
of detailed internal construction specifications (including construction process,
safety precautions, and construction process inspection checklist) and
successful engineering cases in schools, hotels, and even hospitals of similar
scale.
3-2 BeneVision TM80 Telemetry Monitor Service Manual
Page 25
The hospital builds a new WLAN to cover areas less than 2000 square meters for
the TM80 and there are no other requirements except for connection to
Mindray monitors: Mindray contacts the construction organization and
completely uses the network devices and configurations developed and
verified by Mindray. Mindray defines specification requirements and
acceptance methods, inspects the hospital by sending field engineers to the
hospital and confirms the requirements on site. Compared with the previous
circumstance, Party A for network deployment engineering is changed from
the hospital to Mindray. Mindray needs to play a greater role in supervision.
This chapter focuses on wireless network deployment requirements. The
architecture and configuration requirements of Mindray’s wired network are
described in another document.

3.2 Network Requirements of the TM80
The TM80 transmits vital signs of patients in real time. The requirements for
real-time and reliability are higher than those for audio and video services. The TM80
is powered by a battery. It adopts low power Wi-Fi technology. Therefore, the
network needs to meet specific requirements to ensure reliable operation.
The network requirements of TM80 can be classified into six types:
Wireless coverage
AP capability and compatibility
WLAN features
EAP Requirement for RADIUS Server and Certs
Network service and VLAN
Some important settings of network device
The first four types are decided by infrastructure of network. They can’t be modified
easily. If the network does not meet the requirements before TM80 is installed,
network dropping-off may happen easily after installation.
The fifth and sixth types belong to configuration of network. They need hospital IT
department’s help to achieve. According to experience of Mindray, the two types
can guarantee reliable performance of TM80 effectively. If any requirement is not
met, network dropping-off may happen in certain situation. If the number of
devices using the same network is small, and no device needs high wireless
bandwidth, the possibility of dropping-off can be reduced.

3.2.1 Requirements for Network Feasibility
Before installing TM80 telemetry monitors, it is very important to confirm network
feasibility.
Wireless coverage, WLAN features and AP capability and compatibility are decided
by infrastructure of network, infrastructure of network can’t be modified easily. If the
network does not meet the requirements before TM80 is installed, network
dropping-off may happen easily after installation.
3.2.1.1 Requirements for the Wireless Coverage
The wireless coverage must be well controlled to ensure that TM80 can achieve the
maximum data-rate and the lowest packet loss ratio. TM80 data is real-time
upstream data streams and is similar to VoIP data. Monitoring data carries real-time
physiologic information about patients. Therefore, reasonable wireless coverage
must be provided for monitors. In particular, because the telemetry device TM80 is
worn on human body, the signal may become poorer due to blocking of human
body.
The requirements of the TM80 for wireless coverage are as follows:

shall be less than 1%.
Co-channel interference is the most obvious interference for Wi-Fi. The signal
strength of the nearest AP perceived by the wireless monitor must be 20 dB higher
than that of other APs on the same channel. Take 2.4 GHz band as an example. The
following channel deployment is recommended to realize Wi-Fi coverage similar to
cellular coverage.
For co-channel interference, the interference between floors needs to be considered
and the following case should be avoided: a pair of APs is set nearby between two
floors and is working on the same channel. Different SSIDs of the same AP do not
generate co-channel interference (CCI) . CCI from different AP but Same SSID can be
accepted in 2.4G band, but this is highly recommended to be avoided.
3.2.1.2 Requirements for the AP capability
Because the low-power WIFI module is sleeping periodically and the capability for
dealing with wireless data is reduced, it is necessary to use high-performance AP to
BeneVision TM80 Telemetry Monitor Service Manual 3-11
Page 34
enhance the stability of total system. Mindray tested a lot with TM80 and Cisco APs,
the compatibility of Cisco AP is proven good.
We recommend using the network equipment verified by Mindray. This verification
activity includes confirmation of network architecture, equipment model, firmware
version, and specific configurations.
If network equipment whose compatibility is not confirmed by Mindray is used,
potential risks may exist during operation of the TM80. In this case, Mindray
recommends the customer to perform pilot run of the TM80 for at least 24 hours
first to ensure that the equipment is compatible.
Device density needs to be controlled. If too many devices are mounted under one
AP, competition among devices becomes fiercer. For low power consumption Wi-Fi,
high data loss probability will be caused. Therefore, the number of devices under
the same AP must be controlled. The TM80 requires one AP to mount a maximum of
16 devices.

3.2.1.3 Requirements for WLAN Features
The requirements of the TM80 for WLAN features are as follows. If WLAN is of other
features, e.g. using 802.11ac, TM80 will not support, and can't connect to network.
The TM80 adopts low power consumption Wi-Fi technology. If the amount of
broadcast or multicast data is too large on the network, the device wake-up time
increases, the standby duration is shortened, and even Wi-Fi transmission
interruption is caused. Therefore, the TM80 must use an independent VLAN and
work in a different network segment from the CMS, so as to control the amount of
broadcast data. An AP can be configured with multiple SSIDs and associated with a
VLAN. The TM80 needs to use an independent SSID.

addresses for the telemetry VLAN to ensure that the TM80 can obtain an IP
address. If static IP addresses are used, make sure that the IP address of each
device is unique.
Multicast
The TM80 transmits device discovery packets over UDP so that the CMS can discover
it and establish a connection. Transmission over UDP can be in multicast or
unicast mode. If the customer uses the multicast mode, multicast transmission
must be enabled on the network. IGMP snooping must be enabled to avoid
transmitting unwanted multicast data to the TM80.
DTIM
Set DTIM = 1, Beacon = 100ms for TM80 vlan.TM80 is working under low-power
mode and waked up by according to AP’s DTIM. If the DTIM is too long, TM80
need more time to wake up so that the throughput become lower, the
probability of offline may increase.
Data rate
If the network supports the low data rate, the channel will become crowded .As a
result, the probability of offline may increase.
IF low data rate are closed, be sure that the RF coverage meet TM80’s requirement.

Quality of Service (QoS)
If the network is used by TM80 and other devices at the same time, it’s
recommended that the QoS level of the SSID and VLAN used by TM80 is set to
highest level to make sure that the data is real-time.

3.6.2 Environmental Survey
Mindray personnel meet with hospital IT, biomedical engineer and clinicians to
agree on network plan and clinical workflow requirements. The network plan should
include coverage, network topology, channel planning, and device model initially
selected.
3-60 BeneVision TM80 Telemetry Monitor Service Manual
Page 83
3.6.2.1 Environment Confirmation
First obtain the following information:
The layout and current pipe distribution map of the floor
coverage requirements
Number estimation of potential wireless terminal users
Then pre-plan bandwidth allocation and location distribution of main devices.
Finally, conduct a site survey. Site survey covers internal decoration structure of the
building (floor area, floor height, wall and ceiling materials, and areas to be covered),
and location where APs can be mounted.
Preparations before field test
Ask the customer to provide the site floor plan, schematic diagrams of floors and
floor height and collect building design drawings and official documents, so as
to get ware of the power supply for rooms and structure foundation (for
example, metal fire path, wall, doors, and passageway).
Ask the customer to provide the schematic diagram of wireless coverage
requirements.
Ask the customer to determine whether all areas need redundancy coverage or
which areas need redundancy coverage.
Ask the customer to provide personnel who are familiar with site conditions so as
to ask them questions about coverage, site layout, available installation points,
and channel planning and estimate the number of potential Wi-Fi devices
under each AP with them (a maximum of 16 devices are recommended for
each AP).

Site test and report
1. Check that the surrounding environment and placement of devices
during the test are consistent with those actually in use.
2. Learn distribution of Wi-Fi devices and other 2.4G products in the wireless
scope.
3. According to the site environment, initially determine the rough
installation locations of APs, find the cleanest channel by using Wireless
network survey tool, for example, channel 11 is relatively cleaner, open
the test AP, and set the channel to channel 11. Use the Wireless network
survey tool to test wireless coverage and ensure that the test can be
passed in the expected coverage of the test AP.
Go to the next expected AP installation location, perform the test again, and record
the results.
Field personnel must ensure that no blind spot exists in the required coverage and
that co-channel interference does not exceed the limit.

1. The maximum indoor transmission distance of wifi is about 50m. In
practice, the distance of distinct vision is recommended to be 25m to
guarantee coverage. If a brick wall blocks the way, the recommended
distance should be divided by 2; if two brick walls block the way, the
recommended distance should be divided by 2 again. If a load bearing wall
blocks the way, the transmission distance would be greatly reduced. For
one load bearing wall, the transmission distance would be divided by 4.
BeneVision TM80 Telemetry Monitor Service Manual 3-63

2. After completing cabling construction, draw the AP cabling diagram to
facilitate system operation and maintenance in the future.
3. Initially select locations of APs according to the actual scenario and
requirements and then make adjustment through field measurement.
Follow the rules: Ensure that all areas can be covered and try to reduce the
number of needed APs.
4. Channels occupied by coverage areas of APs should comply with certain
specifications. APs in nearby coverage areas cannot use the same channel;
otherwise, co-channel interference would be caused during signal
transmission of APs. Take 2.4G band as example, to utilize band resources
to the maximum extent, the most common method is to select three
non-overlapped channels (channels 1, 6, and 11) as the operating band of
the whole system. the channels1, 6, and 11 are mutually adjacent and
partially overlapped (as shown in the figure below) so as to eliminate blind
spots and avoid co-channel interference while obtaining the largest
coverage area.

3.7 Network Deployment Implementation
This section describes the approximate process of network deployment, which is
performed by professional third party and adjusted according to actual conditions.
3.7.1 Preparations before Equipment Installation
1. According to the site test report, determine locations and install the
network cable and power supply cable.
2. Test the network cable and power supply cable for connectivity.
3. Prepare installation tools: mounting brackets needed by APs and
mechanical tools.
4. Ask the customer to provide climbing equipment (if needed) and
available time for operation (daytime, night and specific time).
BeneVision TM80 Telemetry Monitor Service Manual 3-65
Page 88
3.7.2 Roaming Consideration
The following operation is recommended to guarantee the roaming performance:
Plan possible roaming areas, optimize AP coverage, and reduce the number of AP
handovers on the roaming path.
Donot make tm80 roam across different IP subnet.
Ensure that the same SSID is set for APs in the coverage area.
Ensure that all APs on the roaming path are under the control of the same WLC.
Try not to use enterprise-class encryption, which results in longer roaming time.
3.7.3 Services Provided During and After Installation
1. During installation, perform the following tests for wireless devices
(including APs and laptop computers) at the same time: network
connectivity, security performance, and software operation.
2. Make sure that the configurations of APs meet requirements of this
document.
3. According to requirements of the contract, provide wireless device
settings and maintenance training.
4. Provide technical consulting service after installation to ensure that
equipment is used properly.

3.8 Network Verification
3.8.1 Tools and Resources
Laptop computer, where Windows 7 or operating system of a later version is
installed and wireless network card is equipped. We recommended laptop
configured with Intel Centrino Wireless-N adapter. If your laptop is configured
with some other wireless adapter, please make sure the adapter has a high
degree of accuracy.
Wireless network survey tool, we suggest to use professional survey tool such as
tamograph, Wirelessmon or other professional network survey tool.
TM80 main unit

Professional network engineer
NOTE
The personnel who implement the Wi-Fi network survey should be well
trained about Wi-Fi. If professional network engineers are not available,
please ask some third party for help.
3.8.2 Wi-Fi Signal Calibration
Before a Wireless network survey tool (running on laptop computer) is used to test
network coverage, calibrates the RSSI of wireless network survey tool with TM80.
Keep the TM80 and Wireless network survey tool close. The distance between them
is not greater than 30cm and the distance from human body is above 50 cm. Move
the TM80 and Wireless network survey tool at the same time (maintain the previous
distance). When the TM80 reads the following RSSI values: -50dBm,-60dBm, -70dBm
and -80dBm, record the RSSI values read by Wireless network survey tool.
BeneVision TM80 Telemetry Monitor Service Manual 3-67
Page 90
Then calibrate the RSSI of Wireless network survey tool to TM80 when do site survey
(the RSSI of TM80 is the benchmark to wireless coverage).
3.8.3 Confirm Network Feasibility
Wireless coverage and AP capability and compatibility are decided by infrastructure
of network, it can’t be modified easily. If the network does not meet the
requirements before TM80 is installed, network dropping-off may happen easily
after installation.
Verify these requirements to confirm network feasibility. For verification contents
and method, see3.11.2Environmental Survey Table.
Site survey: To confirm coverage, perform coverage test in the asserted areas
including toilet ,corridor, stairs and other place whereTM80 may be used. The
service person can finish the wireless network survey via third-party
professional survey tool such as tamograph, Wirelessmon or other
professionalnetwork survey tool. The RSSI of TM80 is the benchmarkto wireless
coverage. So it’s necessary to calibrates the RSSI of the wireless network survey
tool with TM80. The site survey must be carried out when the network is
operational and other devices are wirelessly connected.During the test, the
WLAN SSID broadcasting function must be enabled for TM80.
RF environment simulation: Some customers may carry out theoretic design for
deployment of APs by using a simulation tool or deploying analysis tool. The
work can accelerate network deployment but air interface detection cannot be
omitted. This is because the location, power, and channel of an AP may be
adjusted during actual deployment.
3-68 BeneVision TM80 Telemetry Monitor Service Manual
Page 91
3.8.4 Network Verification Process
Network Verification aims to confirm coverage, connectivity, service ports, and
network bandwidth. In addition, other configuration requirements of the TM80
need to be confirmed with the IT Dept. of the hospital. For the Verification content
and method see 3.11.3Network Acceptance Table.
This part is completed through two ways: First the hospital completes items
requiring self-check of the hospital’s IT Dept., as indicated in the Network
Verification Table. Then customer service personnel or authorized party confirms
items on site and finally completes the Network Acceptance Table. If any item is
found incompliant during network Verification test, adjustment should be made
before the TM80 is installed.
A laptop computer needs to be used to simulate the TM80 main unit, so as to test
coverage, connectivity, service ports, and network bandwidth. During the test, the
SSID broadcast needs to be enabled to ensure that the SSID can be scanned.

Currently, X.509.v3 is a mainstream certificate standard. It has two main coding
formats: DER and PEM. Certificates in DER format are mainly suffixed with”.cer”, “.der”,
BeneVision TM80 Telemetry Monitor Service Manual 3-73
Page 96
and “.crt”. Certificates in PEM format are mainly suffixed with “.pem”.
The TM80 only supports certificates in PEM format. If you need to use certificates in
other formats, you need to convert the certificates before importing them into the
TM80. The openssl tool (version 1.0.2c or later) is recommended for the conversion,
and you can get the setup file on internet conveniently.
openssl tool preparation consists of two steps: installing an openssl tool and
configuring environment variables.

variables. After this, you can use openssl in the command line interface as shown
below:
Check your certificates’ suffix. If it's not "pem" you should select the appropriate
command to convert.
Steps to converting CA Certs:
Before start converting, we need to know the format of the CA Cert. It could be DER
or Base64.
The DER cert is binary format, and the Base64 cert is text format. So we can figure
out the format by open the cert with notepad. If the content displayed in the
notepad contains "BEGIN CERTIFICATE", then the CA Cert is in Base64 format,
otherwise it is in DER format.
Command for converting the DER CA Cert to PEM cert
openssl x509 -inform der -in [ca].cer -out [ca].pem
Command for converting the Base64 CA Cert to PEM cert
openssl x509 -inform PEM -in [ca].cer -out [ca].pem
NOTE
The file size of the CA Cert should less than 2KB

Steps for converting User Cert
If the User Cert is .pfx file, then use the following steps for converting:
1. Get the file only containing cert
openssl pkcs12 -in [user cert].pfx -clcerts -nokeys -out [user cert].pem
2. Get the file only containing key
openssl pkcs12 -in [user cert].pfx -nocerts -out [user cert key in pkcs12].pem
3. Convert the key from pkcs12 to pkcs8
openssl pkcs8 -topk8 -inform PEM -in [user cert key in pkcs12].pem -outform PEM
-nocrypt -out [user cert key in pkcs8].pem
4. Merge the cert and key to one file
1) Open the [user cert].pem with notepad, only keep the lines between "-----BEGIN
CERTIFICATE-----" and "-----END CERTIFICATE-----" and delete the other lines.

2) Open the [user cert key in pkcs8].pem with notepad, and copy the content of the
key file and paste it to the end of the cert file. And the merged user cert file contains
the following two parts:
Cert parts: lines between "-----BEGIN CERTIFICATE----- "and "-----END
CERTIFICATE-----"
Key parts: lines between "-----BEGIN PRIVATE KEY-----" and "-----END PRIVATE
KEY-----"
