2 Initial Activation of the TagWhen the tag is delivered it does not have any of the necessary configuration settings. Theseenvironment specific settings need to be applied before the tag can connect to the network andthe ERC. The B4 tags are delivered with the battery charged to a storage charge, it is recommendedto fully charge the battery, before activating the tags first time. See charging instructions in chapterCharging the B4 tag on page 25.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 Tag Activator3 on page 5.After successful Activation you will see the MAC address of the tag appears on the ERC list oftags. After successful connection with ERC the configurations can be managed directly from ERCusing Tag Configurations page.2.1 Installing Ekahau Tag Activator 3The Ekahau Tag Activator 3 comes with the Ekahau RTLS installer. When you install EkahauRTLS, you do not necessarily need to install the Ekahau Activator if the target computer cannotbe used to activate tags with a supported Wi-Fi adapter. If you want to install the Ekahau Activatorlater on another computer, simply run the RTLS setup file on the target computer and choose toinstall only the Ekahau Activator. The Ekahau Activator is usually installed on a laptop as theEkahau RTLS software is installed on a server.The Ekahau Tag 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 instructions3. Install a supported Wi-Fi adapter from th eprograms menu: Start -> Ekahau -> Ekahau TagActivator 3 -> Ekahau USB Driver.2.2 Supported Wi-Fi AdaptersPlease visit our website for the complete list of supported Wi-Fi adapters: http://www.eka-hau.com/devices.2.3 Activation ProcedureFor the tags to be able to communicate with the Ekahau RTLS Controller, the tag needs to beactivated 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 IPconfiguration method are required. To activate B4 tags, you need to use the Ekahau Tag ActivatorChapter 2. Initial Activation of the Tag5
3 which you can run from Ekahau Programs menu. After that, follow the following Activator config-uration procedure.2.3.1 Configuring Ekahau RTLS Controller SettingsInput the IP address of the Ekahau RTLS Controller.Figure 2.1. Specifying the Engine IP address and Maintenance intervalIn 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, forinstance, messages are sent frequently to the B4 tag.6Chapter 2. Initial Activation of the Tag
Figure 2.2. Specifying advanced Positioning Engine settingsNoteWhen activating the B4 tags, only an initial setup is required for the tag to associate with thenetwork. All settings can be set and changed from the Ekahau RTLS Controller. Ekahau TagActivator 3 only provides a set of basic settings.2.3.2 Configuring WLAN SettingsInput 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 matchingthe Security Key.Chapter 2. Initial Activation of the Tag7
Figure 2.3. Specifying Wi-Fi network settingsTipIf WEP encryption is used the Activator automatically determines the key type and length fromwhat you type. WEP 64 require 5 Ascii characters or 10 hex digits, respectively WEP 128requires 13 Ascii characters or 26 hex digits.2.3.3 Configuring Wi-Fi Channels in UseIt is recommended to only select the channels used in you network. Activating the unused channelswill only reduce the battery lifetime of the tag. By default, the Scan Interval is 60 seconds. Youmay also use shorter interval, but it will drain faster the battery of the tag. Alternatively you canuse longer Scan Interval and enable Motion Sensor through the Ekahau RTLS Controller afteractivation. This way the tag will scan only when it is in use and moving.8Chapter 2. Initial Activation of the Tag
Figure 2.4. Specifying the channels used in the networkWarningOnly use channels that really exists in you Wi-Fi network. Activating unnecessary channels willreduce the tag's battery lifetime!2.3.4 Configuring IP SettingsCheck the IP settings. If DHCP is used nothing needs to be done. In case your network uses staticIP addressing, type in the IP address range to be used for the B4 tags, Netmask and Gatewayaddresses.TipChapter 2. Initial Activation of the Tag9
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 settings2.3.5 ActivationPress 'Continue' button when all settings are ready.10Chapter 2. Initial Activation of the Tag

3 Configuration After Initial ActivationThe 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 Activatorsoftware or through Tag Configurations in Ekahau RTLS Controller.Ekahau Activator is used for configuring the initial configuration settings that allows connectingthe tag to ERC over the network. After connection is established with ERC, all configurations canbe managed through Ekahau RTLS Controller.3.1 Tag Configuration Settings in ERC Configs PageIn 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 fromthe Tags page. It is also possible to apply a configuration automatically to all new tags via theConfigs page.

4 Tag Operation4.1 Button Activated Location Update and MaintenanceCallIn addition to periodic location updates, the tag can also be set to scan and update it's locationwhen any of the buttons is pressed. After a button press the tag scans and sends the RSSI resultsto ERC immediately. If the Blue button was pressed the TAG will additionally do a maintenancecall to update the settings and to read queued LED/Buzzer alerts and messages. The LEDsindicate the scan success or failure similarly as in the scan activated by the wake up interval. It isalso possible to define button press based events with Ekahau Vision such as alarms. For moreinformation, please refer to Ekahau Vision user guide.Ekahau RTLS Controller recognizes the B4 tag's button presses as different scan reasons:● Red button corresponds "scanreason 1 = Button"● Blue button corresponds "scanreason 6 = Button2"● Menu button corresponds "scanreason 8 = Button3"4.2 Safety Switch Activated Location UpdateIf the safety switch is pulled out from it's original position, the tag will update it's location to theERC with the Safety Switch flag. If the location update is not succesful, the tag will retry until thesuccesful update. The Safety Switch can be used to send alerts to personnel via Ekahau Visionwhen the switch is pulled out. It is advised to keep the safety switch pulled out while the situationis in progress to avoid the accidental cancellation of the alert. For more information, please referto Ekahau Vision user guide.Figure 4.1. Safety switch operation4.3 Working with the DisplayThe B4 tag's OLED display can be used to read messages sent from Ekahau Vision and EkahauRTLS Controller. The B4 reads the queued messages during maintenance updates which aremade at regular intervals defined by the maintenance interval or when the Red button is pressed.Chapter 4. Tag Operation21
Thus, if the maintenance interval is 60 seconds, the tag can read the new messages every 60seconds. This needs to be kept in mind if urgent messages need to be sent to the tag. When thetag receives a new message, a small notification sound is played.It is possible to send 160 character long instant messages and standard messages to the B4 tag.In Ekahau Vision the message size is limited to 40 characters as the message includes additionallocation information. The maximum number of messages that can be saved to the tags memorydepends on the length of the messages. For example, the tag can save 9 messages that are 100character long and 15 messages with 50 characters.Figure 4.2. An example message4.3.1 Instant MessagesAs the name implies, an instant message is displayed at the display right away. If the instantmessage was sent by a triggered event, the tag will also display the zone where the event wastriggered. To exit from the instant message, press and hold the Menu button. Note that in contrastto the standard messages, instant messages will not be saved to the tag's memory and will bereplaced by another incoming instant message.4.3.2 Standard MessagesWhen a standard message is received, a "Message pending" is displayed. To read the standardmessage:1. Press and hold the Menu button to access the tag's Messages menu2. By default, the selector is automatically over the latest message, now simply press the Menubutton to read the messageThere is two ways to exit from the Message reading screen:● Press the Menu button to either delete the message or to go back to Messages menu whereyou can read all the messages in the tag● Press and hold the Menu button to exit from the tag's menusYou can read the saved standard messages as follows:1. Press and hold the Menu button to enter the tag's Main menu2. Browse to Messages menu with the Blue or Red button and press the Menu button to enter3. Use Blue or Red button to browse to the message you want to read and press the Menubutton to read itTo delete a standard message, follow the instruction explained above to first access the messagereading screen and then do following:22Chapter 4. Tag Operation
1. Press the Menu button2. Browse to Delete and press the Menu button to delete the message3. After the delete, you will get back to the Messages menu where you can continue reading/delet-ing messages or go back to the Main menuNoteYou can exit from the tag's menus whenever by pressing and holding the Menu button.TipYou can disable the tag's buzzer by entering the Main menu and selecting Enable silentmode.TipFor more information on how to send messages to the B4 tag, please refer to Ekahau Visionand Ekahau RTLS Controller User Guides.4.4 Load BalanceThe B4 tag supports access point load balance from firmware 1.2.0 onwards. Should the nearest(strongest) access point reject tag association attempt because of the limit of simultaneous clientassociations is reached, tag automatically searches the second strongest access point in thenetwork and associates to it. In case the second strongest access point is also unavailable (becauseof the maximum number of simultaneous clients is reached there too), tag will continue searchingthe third strongest for connection.4.5 Smart RoamingNormally tag stays associated to the same access point until the connection is almost lost. TheEkahauB4 tag (from firmware 1.2.0 onwards) keeps track of the signal strengths of the accesspoints. In case an access point with signal strenght stronger than 10 dBm or more than the onetag is currently associated is found (from the same network), tag automatically switches to thataccess point.4.6 Resetting to Factory SettingsThe tag can be reset to factory setting with the following button sequence . Note that you need toconnect the tag to the charger first to enable the reset sequence. Tag can be removed from thecharger, but the reset sequence must be initiated within 5 seconds after removal. During this timetag will show continuos green light on the right LED.Chapter 4. Tag Operation23
1. Press and hold the Blue button until Right LED flashes orange. If the tag is busy this may takeeven 20 seconds.2. Then immediately release the Blue button button and press down the Red button .3. After approximately 2 seconds both LED’s flash orange. If the tag is busy, it may flash onlythe Right LED.4. The tag has now been reset to factory settings. The tag is in reset mode when it does notexecute button scan as defined in section Button Activated Location Update and MaintenanceCall on page 21 and pressing the Menu button does not turn on the display.NoteResetting the tag to factory settings removes all messages from its memory!4.7 Firmware UpdateThe tag firmware can be updated wirelessly using ERC. The firmware is uploaded to the tags fromthe Tag Properties page or directly from Tags page in ERC. Follow instruction in the ERC UserGuide for updating the firmware.NoteIf the Tag battery level is below 50% - or below 10% when in charging - the FW update is notallowed. The corresponding error code in ERC is TU. To update the firmware, please firstrecharge the battery and try again.4.8 Optimizing Battery LifeThe B4 Wi-Fi tag uses an ultra-low power system-on-chip architecture that lowers the powerconsumption to minimal, but to ensure optimal performance with targeted lifetime, here are someconsiderations.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 scansand decreases battery lifetime.● When using dynamic IP addressing tune the DHCP server to provide very long lease timesfor tags.● The tag supports roaming between subnetworks. This feature renews tag’s IP addresswhenever the access point association changes. Since renewing IP addresses consumeslarge amounts of energy, it is strongly recommended not to use the network wide dynamicaddressing feature if it is not needed.● Tune the wake up settings to match your application needs. More frequent updates lower thebattery lifetime.24Chapter 4. Tag Operation
TipThe battery level can be checked by briefly pressing the Menu button. The textwill disappear automatically in a few seconds.4.9 Turning off the B4 TagThe B4 tag can only be turned off by resetting the tag to factory settings which is explained inchapter Resetting to Factory Settings on page 23. To continue using the tag after resetting, youhave to re-activate it following the instructions explained in chapter Activation Procedure on page 5.NoteTurning off the tag's display by exiting from the tag's menus, will not turn off the tag! The tagwill stay operational until it is reset to factory settings.4.10 Charging the B4 tagFigure 4.3. Connecting the tag with a Single ChargerChapter 4. Tag Operation25
Figure 4.4. B4 tags in Multi ChargerThe B4 tag is delivered with the battery charged to a storage charge, and it is recommended tofully charge the batteries before first time activating the tag. To ensure the tag battery is full, pleaseput the tag in to a charger for 4 hours. To remove the charger plug, release the plug by pressingthe latches on the plug and pull the plug out.The tag will give a notification when the tag battery is low. Connect the charger and the Right LEDwill show orange light during the charging. after the tag is fully charged the Right LED will turngreen. If the tag battery is completely empty, the tag will automatically turn off. After a charger isconnected, the tag will automatically return to it's normal function, maintaining last settings.The Ekahau supported adapters are1. Ekahau C-T301B Charger2. Ekahau C301B-10 Multi ChargerNoteIn case the tag battery is completely empty, typically when left empty and uncharged for severaldays, it may take a long time for the tag even to turn on the orange led.
