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.
11 Chapter 2. Initial Activation of the Tag Figure 2.6. When all the settings are done, you can start activating the tags The Activation process has now started. The list of the activated tags will appead on the area below.
Chapter 2. Initial Activation of the Tag 12 Figure 2.7. The Activator is ready to start activating the tags Put the tag in charger and while in charger, within three seconds press and hold the tag's button at least five seconds to activate it. During this time tag's LED is red. If activation was successful the tag will vibrate and the green LED will blink, with unsuccessful activation the LED blinks red. After successful activation, the tag MAC address appears on the activation window, showing Ok status. Repeat this for all the tags to be activated.
13 Chapter 2. Initial Activation of the Tag Figure 2.8. The Activator has activated one tag After completing activating the tags, click the 'Stop Activation' button and exit 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 with 'Save As Default' the setup will be the default every time the Activator is started.

In active mode a location update is done immediately when the tag notices a location beacon. In passive mode the recent observed location beacon ID is sent to EPE only when location update is initiated by other stimuli such as periodic or motion wakeup. Disabled, Passive Mode, Active Mode Advanced Scan Settings Initial Scan Count Number of scans the tag does on each triggered scan despite the triggering event. Used to improve the accuracy in difficult conditions and for rarely scanning applications 1 - 10 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. 3.2 Tag Actions Available in ERC Tags Properties Page Setting Description Values (Default underlined) User Data Name A user given name for tag Free text Custom A custom note Free text Member of Groups The groups the tag belong to List of groups or "No Groups cre-ated" if no groups exist.

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 The W4 tags are attached to the Single Charger as illustrated below.
