Chapter 1. Introduction

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 T301W tags are delivered with the battery charged to a storage charge.
Tag activation is done using Ekahau Activator software that configures Ekahau T301 family tags
wirelessly. The activation of the tags is explained in more details in chapter Installing Ekahau
Activator T301 on page 3.
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 T301
The Ekahau Activator T301 can only be installed using the Ekahau RTLS installer. When you
install the 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.
To install Ekahau Activator as a stand alone:
1. Choose a laptop (or a desktop with a supported Wi-Fi adapter) computer with Windows XP
or 2000, at least 256 MB of memory, PC card slot, and 100 MB of free hard disk space
2. Install a supported Wi-Fi adapter using the driver provided by Ekahau. For list of supported
adapters, please visit http://www.ekahau.com/devices
3. Run the RTLS setup file from it's location, and follow the on-screen instructions
2.2 Supported Wi-Fi Adapters.
You can find the latest supported Wi-Fi adapters from our website:
http://www.ekahau.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 necessarry 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 T301W tags, you need to use the Ekahau Activator
T301 which you can run from Ekahau Programs menu. After that, follow the following Activator
configuration procedure:
2.3.1 Configuring Ekahau RTLS Controller Settings
Input the IP address of the Ekahau RTLS Controller. The Maintenance Interval is by default 240
seconds, but shorter interval can be used if LED and Vibration alerts are sent frequently to the
Chapter 2. Initial Activation of the Tag

T301W tag. After completing the "Positioning engine settings", the status bar should show "Engine
Ok". These are the minimum settings needed.
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.
Figure 2.2. Specifying advanced Positioning Engine settings

Chapter 2. Initial Activation of the Tag

Note
When activating the T301W tags, only an initial setup is required for the tag to associate with
the network. All the settings can be set and changed from the Ekahau RTLS Controller. Ekahau
Activator T301 only provides a set of basic settings.
2.3.2 Configuring Scan Settings
Select which location update method you want to use. Select "Generic (ELP)" in case you want
the tag(s) to communicate with the Ekahau RTLS Controller in associated mode where the tag
associates to the network everytime it sends an ELP location update packet. If you want to use
the tag(s) in beaconing mode, select the mode that corresponds to your Wi-Fi network vendor. In
beaconing mode the tag does not associate with the network.
In the "Count" field you can define how many times the tag sends a location update packet during
each location update. 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 on move.
In addition to Scan Settings, you need to define the correct area the tag is used in. FCC for North
America, ETSI for Europe and Japan for Japan. The software automatically disables the channels
not available for the area selected. It is also recommended to only select the channels used in
you network. Activating the unused channels will only reduce the battery lifetime of the tag. After
completing the settings the status bar should show "Scan Ok"
Figure 2.3. Specifying the Scan Interval and the channels used in the network
Chapter 2. Initial Activation of the Tag
5

Warning
Only use channels that really exists in you Wi-Fi network. Activating unnecessary channels will
reduce the tag battery lifetime!
2.3.3 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. After WLAN settings are completed the status bar should
show "WLAN Ok"
Figure 2.4. 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.
2.3.4 Configuring IP Settings
Check the IP settings. If DHCP is used nothing needs to be done. In case your network requires
Static IP to be used, type in the IP address range to be used, Netmask and Gateway addresses.

Chapter 2. Initial Activation of the Tag

Tip
If you only activate a single tag and wish to use static IP setting. Please input Start IP Address
= End IP Address.
Figure 2.5. Specifying IP settings
2.3.5 Activation
If the supported Wi-Fi adapter is inserted and all the settings are shown OK in the status bar, the
Activate button should now be active. To continue Activating the Tags press the "Activate" button.

Figure 2.7. The Activator is ready to start activating the tags
When the activation window appears, the Activator is ready to start activating the tags. To activate
the tag, press the small Activation Button on the side of the tag. The tag will play the vibrator
when the Activation Button is pressed. After successful activation, the tag will blink green LED
three times. In addition, the TAG MAC address appears on the activation window, showing Ok
status. Repeat this for all the tags to be activated.
Note
If WPA2-PSK encryption is used, it might take even 10-15 seconds before the tag appears to
EPE's Tags list.

After completing activating the tags, close the activation window.
Tip
After you have finished the activation, you can save the configuration for future use from the
file menu. If you save the settings on Ekahau Activator T301.ini the setup will be the default
every time the Activator is started.

3 Configuration After Initial Activation
The tag can be adjusted for each application and network settings by adjusting a set of parameters.
The parameters can be changed wirelessly after resetting the tag by using the Ekahau Activator
software or through Tag Configurations in Ekahau RTLS Controller.
Ekahau Activator is used for configuring the initial configuration settings that allows connecting
the tag to ERC over the network. After connection is established with ERC, all configurations can
be managed through Ekahau RTLS Controller.
3.1 Tag Configuration Settings in ERC Configs Page
In Ekahau RTLS Controller it is possible to create a configuration to a single tag or a group config-
uration to multiple tags. After the tags are activated, the configurations are applied to tags from
the Tags page. It is also possible to apply a configuration automatically to all new tags via the
Configs page. The list of available settings is in the following table:
