5 Chapter 2. Initial Activation of the Tag
2 Initial Activation of the Tag
When the tag is delivered it does not have any of the necessary configuration settings. These
environment specific settings need to be applied before the tag can connect to the network and
the ERC. The W4 tags are delivered with the battery charged to a storage charge, it is recommended
to fully charge the battery, before activating the tags first time. See charging instructions in chapter
Charging the W4 tag on page 22.
Tag activation is done using Ekahau Activator software that configures Ekahau tags wirelessly.
The activation of the tags is explained in more details in chapter Installing Ekahau Activator
3 on page 5.
After successful Activation you will see the MAC address of the tag appears on the ERC list of
tags. After successful connection with ERC the configurations can be managed directly from ERC
using Tag Configurations page.
2.1 Installing Ekahau Activator 3
The Ekahau Activator 3 comes with the Ekahau RTLS installer. When you install Ekahau RTLS,
you do not necessarily need to install the Ekahau Activator if the target computer cannot be used
to activate tags with a supported Wi-Fi adapter. If you want to install the Ekahau Activator later on
another computer, simply run the RTLS setup file on the target computer and choose to install
only the Ekahau Activator. The Ekahau Activator is usually installed on a laptop as the Ekahau
RTLS software is installed on a server.
The Ekahau Activator 3 installation package can also be downloaded from http://www.eka-
hau.com/download/activator.
How to install Ekahau Activator:
1. Choose a laptop (or a desktop) computer running Windows 7 (32 or 64bit operating system)
with a supported Wi-Fi adapter (and driver supporting virtual Wi-Fi), at least 256 MB of memory,
free USB port, and 3.5 MB or more free hard disk space.
2. Run the Ekahau Activator setup file from it's location, and follow the on-screen instructions
3. Install a supported Wi-Fi adapter from th eprograms menu: Start -> Ekahau -> Ekahau
Activator 3 -> Ekahau USB Driver.
2.2 Supported Wi-Fi Adapters
Please visit our website for the complete list of supported Wi-Fi adapters: http://www.eka-
hau.com/devices.
2.3 Activation Procedure
For the tags to be able to communicate with the Ekahau RTLS Controller, the tag needs to be
activated e.g. the tag needs to be given the necessary parameter to associate with the network.
At least the IP address of the Ekahau RTLS Controller, SSID of the network used and the IP
configuration method are required. To activate W4 tags, you need to use the Ekahau Activator 3
Chapter 2. Initial Activation of the Tag 6
which you can run from Ekahau Programs menu. After that, follow the following Activator configur-
ation procedure.
2.3.1 Configuring Ekahau RTLS Controller Settings
Input the IP address of the Ekahau RTLS Controller.
Figure 2.1. Specifying the Engine IP address and Maintenance interval
In case Engine Port, Maintenance port, and/or Maintenance IP needs to be changed, go to
"Advanced" mode. The (Periodic) Location Update Interval is set to 60 seconds and the (Periodic)
Maintenance Interval is set to 240 seconds by default , but shorter interval can be used if, for
instance, messages are sent frequently to the W4 tag.
7 Chapter 2. Initial Activation of the Tag
Figure 2.2. Specifying advanced Positioning Engine settings
Note
When activating the W4 tags, only an initial setup is required for the tag to associate with the
network. All settings can be set and changed from the Ekahau RTLS Controller. Ekahau Activator
3 only provides a set of basic settings.
2.3.2 Configuring WLAN Settings
Input the Wi-Fi Network SSID and select the Encryption method used. If WEP 64/128 or WPA2-
PSK is used type in the network key as well. Normally, 1st Security Key Index (for WEP encrytion)
is used. Should you use key index other than the first one, please select the key index matching
the Security Key.
Chapter 2. Initial Activation of the Tag 8
Figure 2.3. Specifying Wi-Fi network settings
Tip
If WEP encryption is used the Activator automatically determines the key type and length from
what you type. WEP 64 require 5 Ascii characters or 10 hex digits, respectively WEP 128
requires 13 Ascii characters or 26 hex digits.
2.3.3 Configuring Wi-Fi Channels in Use
It is recommended to only select the channels used in you network. Activating the unused channels
will only reduce the battery lifetime of the tag. By default, the Scan Interval is 60 seconds. You
may also use shorter interval, but it will drain faster the battery of the tag. Alternatively you can
use longer Scan Interval and enable Motion Sensor through the Ekahau RTLS Controller after
activation. This way the tag will scan only when it is in use and moving.
9 Chapter 2. Initial Activation of the Tag
Figure 2.4. Specifying the channels used in the network
Warning
Only use channels that really exists in your Wi-Fi network. Activating unnecessary channels
will reduce the tag's battery lifetime!
2.3.4 Configuring IP Settings
Check the IP settings. If DHCP is used nothing needs to be done. In case your network uses static
IP addressing, type in the IP address range to be used for the W4 tags, Netmask and Gateway
addresses.
Chapter 2. Initial Activation of the Tag 10
Tip
If you only activate a single tag and wish to use static IP setting, enter same IP address in
'Start IP Address' and 'End IP Address'.
Figure 2.5. Specifying IP settings
2.3.5 Activation
Press 'Continue' button when all settings are ready.

Note
1) Network wide DHCP enables roaming between sub-networks. With this setting the tag refreshes
its IP address whenever the tag associates with a new access point. It is not recommended to
use the feature, if not required, due to higher power consumption
Note
2) Using the Advanced Scan Settings need a careful consideration. The scanning consumes
a high amount of energy, and the more scanning is done the less battery life the tag has. Typ-
ically these parameters are used to improve accuracy in very difficult conditions or in cases the
tag otherwise would scan rarely.

21 Chapter 4. Tag Operation
4 Tag Operation
4.1 Button Activated Location Update
In addition to periodic location updates, the tag can also be set to scan and update it's location
when any of the buttons is pressed. After a button press the tag scans immediately and sends the
results to ERC. The LEDs indicate the scan success or failure similarly as in the scan activated
by the wake up interval.
4.2 Maintenance Call
The W4 performs normal periodict Maintenance Calls. The interval of the Maintenance Calls can
be set during the initial activation or after the activation via Ekahau RTLS Controller.
The W4 tag does not perform button activated maintenance calls. Instead, when the button is
pressed, ERC will respond to the Location Update with ACK packet which can indicate if there is
pending Maintenance command message. If there is, the W4 will perform automatically Maintenance
Call.
4.3 De-activation / Resetting to Factory Settings
To deactivate the W4 tag, put it into charger and within three seconds press and hold the button
for at least ten seconds. During this period the LED will show orange light. The tag vibrates and
blinks the LED three times as green and red in turns when successfully reset.
4.4 Firmware Update
The tag firmware can be updated wirelessly using ERC. The firmware is uploaded to the tags from
the Tag Properties page or directly from Tags page in ERC. Follow instruction in the ERC User
Guide for updating the firmware.
Note
If the Tag battery level is below 10 % the FW update is not allowed. The corresponding error
code in ERC is TU. To update the firmware, please first recharge the battery and try again.
Note
W4 firmware update requires a new UDP port allocation from EPE (defaults to 8562). See
“Global Server Settings” page in EPE Config Utility.
Chapter 4. Tag Operation 22
4.5 Optimizing Battery Life
The W4 Wi-Fi tag uses an ultra-low power system-on-chip architecture that lowers the power
consumption to minimal. This enables running tags with same batteries for several years. However,
to get the maximum lifetime from your tags you should take care that your network and tag config-
uration supports all possible power save features.
The principal in optimizing battery life is to determine the maximum interval for location updates,
still sufficient for the use case, to minimize the amount of time the tag is active.
Recommendations for optimizing battery lifetime:
● Scan only channels that are in use in your network. Typically, because of overlap of channels,
there are only 3 or 4 channels in use from the 11 (or 13/14) available.
● Use single SSID whenever possible. Using multiple SSIDs requires additional network scans
and decreases battery lifetime.
● When using dynamic IP addressing tune the DHCP server to provide very long lease times
for tags.
● W4 tag supports roaming between subnetworks. This feature renews tag’s IP address whenever
the access point association changes. Since renewing IP addresses consumes large amounts
of energy, it is strongly recommended not to use the network wide dynamic addressing feature
if it is not needed.
● Tune the wake up settings to match your application needs. More frequent updates lower the
battery lifetime.
4.6 Turning off the W4 Tag
The W4 tag can only be turned off by resetting the tag to factory settings which is explained in
chapter De-activation / Resetting to Factory Settings on page 21. To continue using the tag after
resetting, you have to re-activate it following the instructions explained in chapter Activation Pro-
cedure on page 5.
4.7 Charging the W4 tag
The W4 tag is delivered with the battery charged to a storage charge, and it is recommended to
fully charge the batteries before first time activating the tag. To ensure the tag battery is full,
please put the tag in to a charger for 4 hours.
The tag will give a notification when the tag battery is low. Connect the charger and the LED will
show red light during the charging. after the tag is fully charged the LED will turn green. If the tag
battery is completely empty, the tag will automatically turn off. After a charger is connected, the
tag will automatically return to it's normal function, maintaining last settings.
The Ekahau supported adapters are
1. Ekahau W4 Single Charger
2. Ekahau W4 Multi Charger
