1. Introduction 
Yanzi Networks delivers an end-to-end, horizontal, and all-IP software Internet of Things platform. 
We offer sensors, gateways, and Cirrus, a cloud platform solution packaged into a Software as a 
Service solution (SaaS) for Smart Building applications. The horizontal and all-IP approach 
provides a solution that is fast, robust, and transformative. 
1.1 Best Technology 
All IP technology, all the way to the sensor, ensures powerful scaling to thousands of sensors and 
excellent cost efficiency. Yanzi Networks focus on open standards and leverage the widely 
deployed protocols such as 4G/LTE, Ethernet, Wi-Fi, and the low power "brother" to Wi-Fi, IEEE 
802.15.4, which enables battery operated sensors to last for 10+ years. 
1.2 Easiest to install 
Automatic security provisioning provides best-in-class installation provided by the patent pending 
zero-touch configuration. Sensor installation do not need professional installers but can leverage 
the employees on site. The optimized power management deliver very long battery life which 
secure a minimum of maintenance required once installed.  
1.3 Enterprise security 
Yanzi Networks combines ease of installation and maintenance with enterprise security. It is a 
highly secure solution with all links in Cloud and to Gateway being authenticated with client and 
server certificates and all communication is made using SSL encryption. All local communication, 
between the sensors and the Gateway, is encrypted for both wired and wireless solutions. Each 
sensor has an individual key and can be revoked remotely.  
1.4 Cirrus Software as a Service 
The Yanzi Cirrus Software as a Service provides Device and Gateway management at a new level. 
The Cirrus data model allow access to any data originating from any location with a uniform 
interface without the need to understand the sensor details. A secure Gateway-to-Cloud 
connector to multiple redundant link servers provides reliable remote access to Gateway. 
The Cirrus open API is a JSON over web socket API where all operations are authenticated. The 
API support both subscriptions models as well as request/response.

2. Installation Planning 
2.1 Infrastructure 
The infrastructure has two parts: The Gateway and the IoT network. The Gateway is the brains of 
the system and manages all sensors, collects all data, and keeps a communication channel open 
to the Cloud. The IoT network is required to enable sensors to communicate with the Gateway. 
The IoT network is completely built on IP communication, same as on the Internet. The IoT 
network is built using one or more Access Points, just like a WiFi network is built. The Access 
Points communicate with the Gateway using standard Ethernet connectivity. For more 
information on networks and wireless technologies, please see support sections below. 
Before ordering any infrastructure products, the first step is to decide type of Internet connection 
and way to build the IoT network according to the following sections. 
2.1.1 Connecting the Gateway to Internet 
Gateways can be connected to the Internet in two ways: 
1) Sharing the Internet connection already available in the building or 
2) Using a mobile broadband uplink 
Sharing the Internet connection does not mean the IoT network must run on the corporate 
network. It means using a separate port on the customer’ firewall to create a separate network 
that only provides Internet access. 
2.1.2 Building the IoT Network 
The IoT Network can be built in two ways. 
1) If there are Ethernet cabling available in the building, it may be possible to use a single 
Gateway and connect that to one or more Access Points using those Ethernet cables. 
2) If there are no Ethernet cabling available and it is not possible to pull new cables, the IoT 
network is built using one or more Gateways connecting to the cloud over mobile 
broadband. Most of the Gateways have access points capabilities already built-in so a 
small IoT network can be created around each Gateway. These Gateways all 
communicate separately with the Cloud. 
2.1.3 Infrastructure Examples 
Small system where only one Gateway is enough to create the wireless IoT network. Internet 
connectivity can be provided using Ethernet (on the left) or using built-in mobile broadband in the 
Gateway (on the right).

Large system reusing Ethernet infrastructure in building and where Internet connectivity can be 
provided by sharing a port on the existing firewall or using an external mobile broadband router. 
• Gateway and Access Points needs a network with a DHCP server to get IP addresses 
assigned.  
• The Gateway communicates with the Access Points using UPnP and SSL over Ethernet 
• Internet connection only requires outgoing port 443 and 4445. No inwards connection 
required. Gateway connects automatically to the Yanzi server. 
• All communication links are encrypted

2.2 Use Cases 
Depending on which use case to cover, the type and position of sensors may vary. Two typical 
use cases are shown below for space utilization and comfortability. 
2.2.1 Space Utilization 
For space utilization, Yanzi Motion/Presence sensors are added under the table at each work 
desk chair and at each chair of larger conference rooms (typically rooms with 6 chairs or more) 
to detect usage. For room usage, Yanzi Motion/Presence or Yanzi Motion+ is placed on the wall 
(rooms larger than 20m2 are recommended to use two sensors to make sure the whole room is 
covered). Selection between Motion/Presence sensor and Motion+ sensor depends on if 
comfortability use case also should be covered as the Motion+ sensor monitors more things than 
the Motion/Presence sensor. 
Motion/Presence sensors may also be used for restroom utilization to monitor each stall as well 
as the washroom. 
Footfall cameras may be placed in the ceiling of each entrance to the building and can as well be 
placed at the entrance to any area where specific information is wanted. The footfall cameras are 
connected to the Gateway using Ethernet/PoE. This proposal do not focus on footfall cameras. 
2.2.2 Comfortability 
For comfortability, the work environment is monitored using for example CO2, temperature, 
humidity, barometric pressure, volatile organic compounds (VOC), ambient light and ambient 
noise sensors. Yanzi Comfort sensors are placed in each room (conference room, phone booths, 
locker room, etc.) where people are present for longer periods of time as well spread out in open 
work spaces. In open work spaces, recommendation is to use one Yanzi Comfort for each 15-25 
work desks. 
Yanzi Motion+ are used to monitor occupancy and light at work desks (preferably placed in the 
ceiling where it covers about 6-8 work desks depending on height of ceiling). It is also used to 
monitor utilization of smaller rooms such as conference rooms, phone booths, locker rooms, 
storage rooms, kitchens, restrooms, etc.

2.3 Installation Tool 
One of the important parts after the installation is to know where sensors have been placed. The 
mapping between the sensor unique ID and the physical location is done at time of installation 
using the Yanzi installation tool in Yanzi Live. This is a browser based installation tool that allows 
for quick installation of many sensors. 
Prior to installation, make sure the floor map(s) has been provided to Yanzi and added to your 
account. 
2.4 Privacy 
It is strongly recommended to inform personnel of the reasons for the installation, that their 
privacy is respected and maintained at all times, and clarify that no images, video, or sound is 
ever recorded. 
The correct process for this is up to each company to decide but Yanzi recommends the 
following as a basis: 
1. Send an email with information two weeks prior to installation 
2. Leave a note on each person’s desk at the time of installation 
3. Send an email again after installation is done reminding why this is done 
See section 15 for examples of wording.

3. Installation of Infrastructure 
Gateways are recommended to be registered prior to installation. Register means connecting the 
Gateway to a specific account. Users can then be added or removed from this account to control 
access. Registration is done using the installation tool or provided as remote support by Yanzi. 
Yanzi needs the Gateway ID (printed on the Gateway label), the location name it should have, as 
well as a user with administrative rights for this account. 
Make sure the infrastructure is always built prior to installing any sensors. Install the Gateway 
and connect it to Internet. Install the Access Points and connect them to the same network as 
the Gateway according to the pictures above. 
The wireless IoT network created around Access Points have a range of about 500-1,500 m2 (~ 
5,000-15,000ft2). The actual range depends heavily on walls, obstacles, materials, and number of 
potential mesh nodes (This is very similar to WiFi access points). Wireless coverage is affected 
for example by elevator shafts (lots of metal), bathrooms (water and thick walls), and other radio 
disturbances such as WiFi access points and microwave ovens. 
IoT Access Points (or Gateways with mobile broadband) is shown below with an approximated 
wireless coverage shown as orange circles. In this specific building, two Access Points per floor 
is enough.

4. Teams and Equipment 
Most efficient is usually to have installer teams of 2-3 persons. Multiple teams can work in 
parallel for quicker sensor installations. 1 person places the sensor on the floor map and scans 
the QR code. 1-2 persons place the sensor on the correct spot in the building. 
Each installation team needs 
• Laptop with Chrome browser 
o Internet access is required for the laptop as installation tool is web based 
• QR code scanner 
o Such as the Motorola, Symbol, or Zebra DS6708   
• Plastic bins for carrying sensors 
• Access to all rooms in building where sensors are to be placed

5. Sensor Handling Tips 
5.1 Battery lid 
To open and close the battery lid, gently push the back side label close to the battery lid with your 
thumb and slide the battery lid downwards with your other hand. 
5.2 Sensor element 
The sensor elements must be handled with care as these are sensitive parts. 
5.3 Battery insertion 
The battery powered sensors operate with 2 or 4 batteries. Two batteries makes the product run 
for half the time which is usually 5 years. When using two batteries, please use the bottom two 
battery slots as shown in section 11. Note the polarity when inserting the batteries. Polarity is 
always shown in the sensors battery compartment as well as on the battery itself. 
It is very important to follow the battery requirements when inserting batteries, see section 11 for 
more details. 
Verify that the front panel LED is turned on within 5 seconds after inserting batteries. Note that it 
may only be turned on for a very short while to save battery. If you do not see the LED come on 
even for a short while, please remove the batteries and re-insert them again. If it still doesn’t work, 
please see the Troubleshooting section. 
5.4 External power input 
For sensor requiring an external power supply, insert the USB-C connector on the bottom side of 
the sensor carefully until a “click” is detected. See each product manual for more details. 
Verify that the front panel LED is turned on within 5 seconds after inserting power.

Yanzi Networks  Installation Manual – Smart Office    17 of 42 
5.5 Sensor buttons and switches 
All Yanzi sensors have a status button, a short press on the 
status button will indicate the status using the LED, see 9.1 for 
LED behavior. 
Some sensors ship with batteries already inserted and therefore 
have a power switch. Carefully push the switch to its upper 
position to turn on the sensor. Should you want to turn off the 
sensor, carefully push the switch to its downward position. Use 
a sharp tool such as a paper clip or mobile phone SIM card 
ejector to flip the switch.

6. Placement of Sensors 
General tips on placement 
• Try to place the sensors in discrete locations 
• Place sensors along walls at about  
150-170 cm (60-70 inches) from floor 
• Sensors are attached using adhesive tape 
• Target wood, plastic, or metal surfaces that are flat 
• Avoid wall papers as they may break if sensor must be removed 
• Avoid painted walls when using adhesive tape as modern paint is efficient in repelling 
adhesive tape 
• Dry target surface with a cloth to remove dust, dirt, and grease 
• Remove tape cover and press firmly ON THE SLEEVE for 10 seconds. After 10 seconds, 
the adhesive tape is strong enough to hold the sensor. Full adhesiveness is reached after 
72 hours. 
Yanzi Motion+ 
• Place on wall of smaller rooms such as conference rooms and phone booths 
• Place in ceiling above groups of 4-8 work desks 
Yanzi Comfort 
• Place on wall not close to work desk 
• Place vertically with the power connecter facing downwards 
• Avoid placement near any air ventilation inlets or outlets as this may cause inaccurate 
readings 
• Requires a power outlet within 0.5 meters (longer cables available as accessory) 
Yanzi Presence for work desks 
• Place under work desk about an arm’s length from edge 
Yanzi Presence for conference room chairs 
• Place under conference room table at each chair about an arms length from edge 
Yanzi Presence for conference room corner 
• Place in corner of smaller rooms and along walls in larger rooms 
• Face away from windows to avoid direct sunlight

8. Wireless Communication 
Yanzi sensors operate on world-wide standard physical medias only such as IEEE 802.3 
(Ethernet) and IEEE 802.11 (WiFi) for high performance sensors, and IEEE 802.15.4 for very low 
power sensors. The wireless protocols are all designed by IEEE to operate simultaneously with 
minimum interference. Yanzi uses very low power for IEEE 802.15.4 sensors in order to be 
friendly with WiFi. An advanced back-off/retransmission scheme ensures good coexistence with 
Wifi networks as well as providing minimal impact from unwanted interference. 
IEEE 802.15.4 has similar range to WiFi and normally operates on the same ISM band, 2.4GHz. 
There are Sub-GHz solutions for IEEE 802.15.4 as well but for normal high density installations, it 
is not required for reach. 
For more details on IEEE 802.15.4, please see section 14. 
Sensors communicate periodically (typically every minute but depends on type of sensor) with 
the Gateway. Events are communicated immediately (and not periodically) for fast notifications. 
All communication is full duplex ensuring that all packets are received properly.

11. Battery Requirements 
It is very important to follow these guidelines to avoid serious injuries. Bad handling of batteries 
may cause them to leak, potentially rapidly, creating a risk of injury as the internals of batteries 
are very corrosive. It is recommended to use Alkaline batteries in most use cases and Lithium 
(LiFeS2) for cold use cases. 
• NOTE THE POLARITY OF THE BATTERIES WHEN INSERTING THEM. Polarity is always 
shown in the battery compartment as well as on the battery itself. The plus side is marked 
on the picture below. 
• NOTE THE VOLTAGE OF THE BATTERIES. There are several voltages available for the 
same size of batteries. See the product manual for details on which battery to use. 
• ONLY USE NEW BATTERIES. Batteries older than 1 year should be avoided as they may 
have aged differently and therefore cause harm when used together. 
• NEVER MIX TYPE OF BATTERIES. Only use the same type of chemical compound in all 
batteries. 
• NEVER MIX OLD AND NEW BATTERIES. Make sure all batteries used are from the same 
package. 
• IF BATTERIES GET WARM WITHIN 5 SECONDS AFTER INSERTION, REMOVE THE 
BATTERIES IMMEDIATELY. 
• IT IS RECOMMENDED TO USE PROTECTIVE GLASSES WHEN WORKING WITH 
BATTERIES. 
Note polarity symbols in the battery compartment

11.1 Battery Consumption 
Yanzi sensors are very power efficient. Most battery driven Yanzi sensors consume less than 5uA 
during sleep which is class leading. Sensors wake up periodically to communicate with the 
Gateway with a configurable frequency. Sensors detecting motion communicates with the 
Gateway immediately upon motion for fast response times and goes to sleep for a certain time 
following a motion, called black-out period, to save battery. Things that affect the battery life is 
shown below. Battery life time cannot be guaranteed if used outside of below recommendation. 
Note that default sensor settings may differ from below requirements.

11.2 Note on Lithium Batteries 
There are several types of Lithium batteries on the market in the standard size called AA. First, 
care must be taken to make sure the voltage is correct according to the datasheet; 1.5V, 3.0V, or 
3.6V. 
Yanzi has identified that several suppliers of 1.5V Lithium batteries of type LiFeS2 often produce a 
voltage higher than 1.8V. Voltages above 1.8V may harm products targeted for 1.5V batteries so 
please verify that the battery you use follows the recommendations in the product datasheet.

13.2 High Security Cloud Model 
All access to IoT data is authenticated in the API. All links are authenticated with client and server 
certificates and all communication is made using SSL encryption. 
Data model 
• Authentication server (Orange) signs all certificates as well as redirects the Gateways to 
the correct Link server 
• Link servers (Light Blue) manage Gateways and pass data to Microsoft IoT Hub via API 
Server. 
• API servers (Green) provides a secure interface to analytics partner and acts as an 
aggregator for multiple link servers. 
• Prototocl Translators (Dark Blue) translates Yanzi Cirrus API to other APIs such as MQTT.  
• Local Gateway (Gray) stores all sensor data temporarily to support autonomous operation 
when Internet connection is down
