1Chapter 1. Introduction1 IntroductionThe Ekahau A4 / A4+ Wi-Fi tag is part of Ekahau RTLS (Ekahau Real-Time Location System) thatconsists of Ekahau Wi-Fi location tags, Ekahau RTLS Controller (ERC) software platform and Ekahau Vision end-user application. It is designed to be worn by patients, employees, children and other individuals, and it enables real-time visibility into a persons exact location  enterprise-wide, with reliable room- and sub-room level accuracy. 1.1 Software Release LevelThis User Guide documents the functionality available with software release level, 1.0 onwards.1.2 Features of A4 / A4+The following features are included with this software release:Works with standard 802.11b/g/n Wi-Fi networksSupport for 64/128-bit WEP key, WPA, and WPA2-PSK authenticationStatic and dynamic IP addressingTwo configurable buttons for switching the tag on and resetting the tag to its factory settingsLocation reporting triggered by button, periodic timer, motion, and by Ekahau Location BeaconsSupport for associated and beaconing modes such as Cisco CCX, Aruba, Meru, Aerohive, and Motorola beaconing modesTwo status indication LEDs for determining the tag statusBattery monitoring and reporting ( A4+ reports both external power and back up battery status)Ekahau Location Beacon sensor for room, sub-room, and bay level accuracyActivation using Ekahau Tag Activator 3, standalone tag configuration software.Configuration using Ekahau RTLS Controller1.3 Features specific of A4+Externally powered (3 mm DC standard connector) with a built-in backup CR2-batteryRuns on external power between 2.5V and 5.5V DC (External power supervised) 2.5 mm standard connector for two external programmable buttons

3 Chapter 2. Tag Operation2 Tag Operation2.1 Button Activated Location Update and MaintenanceCallIn 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, if White button (right-hand button on A4+) was pressed the tag will do a maintenance call in addition to the location update . The LEDs indicate the scan success or failure similarly as in the scan activated by the wake up interval.2.2 Resetting to Factory SettingsThe Ekahau A4 / A4+ tag can be reset to factory settings by using a button sequence as follows:1. Press and hold the White button (right-hand button on A4+) until Left LED flashes orange. Ifthe tag is busy this may take even 20 seconds. NOTE: Before the Left LED flashes orange, it may flash green/red depending on the success of the ELP packet which is sent when theWhite button (right-hand button on A4+) is pressed. Do not mind about this and keep on pressing the White button (right-hand button on A4+) until the Left LED flashes orange.2. When the Left LED flashes orange, immediately release the White button (right-hand button on A4+) and press down the Blue button (left-hand button on A4+).3. After approximately 2 seconds both LEDs flash orange.4. The tag has now been reset to factory settings. The tag is in reset mode when it does not execute button scan.2.3 Firmware UpdateThe 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.NoteIf the Tag battery level is below 10 % (applicable on A4+ only if running on internal backup battery) the FW update is not allowed. The corresponding error code in ERC is TU. To update the firmware, please replace the battery and try again.2.4 Optimizing Battery LifeThe A4 / A4+ 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 andtag configuration supports all possible power save features (does not concern A4+ when powered from wall adapter).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.

Chapter 2. Tag Operation 4Recommendations 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.A4 / A4+ tag supports roaming between sub-networks. 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 the battery lifetime.Note that when both LEDs are blinking red the A4 / A4+ tag is either doing a self-test or indicating that the battery is low. 2.5 Turning off the A4 / A4+ TagThe A4 / A4+ tag can only be turned off by resetting the tag to factory settings which is explained in chapter Resetting to Factory Settings on page 3. To continue using the tag after resetting, you have to re-activate it.

Battery polarity and replacementA4 A4+Batteries are replaced by opening the four screws on the backside of the tag. Old batteries maybe removed from the device by pulling them gently upwards. After removing old batteries a 1minute

Chapter 3. Technical specifications 6waiting period must happen before inserting new batteries. New batteries should be placed between the battery springs. Check that the polarity of the batteries is correct. There are battery polarity indicators on the circuit board and inner surface of the front cover. The correct polarity is also showed in photo above. Avoid touching the circuit board and the flex cable when replacing batteries as they may become damaged from static electricity or mechanical impact. Please note that when battery is empty, voltage will rise after some time and tag will try to power up. As a result, you will hear ticking sound from the tag and this sound will stop only when both batteries are removed and both replaced at the same time (A4). Recommendations for choosing and replacing batteries:Always use only new 3V Lithium LiMnO2 CR2 size batteriesReplace both batteries at the same time (only one back up battery used in A4+)Ekahau recommends batteries from ANSMANN, EVE or VARTA as they have been tested during the development of the product. Any standard 3V Lithium LiMnO2 CR2 could be used but the performance may vary depending on the quality of the battery. After batteries have been replaced close the back cover, replace and tighten the screws.3.4 Care and MaintenanceKeep the tag dry. Precipitation, humidity and all types of liquids or moisture can contain min-erals that will corrode electronic circuitDo not use or store the tag in dusty, dirty areas. Its moving parts can be damagedDo not store the tag in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plasticsDo not store the tag in cold areas. When it warms up (to its normal temperature), moisture can form inside, which may damage electronic circuit boardsThe operating temperature of the tag is 0 to 50 ºC. Do not operate the tag outside this temper-ature rangeOpen the tag only for replacing batteriesDo not drop, knock or shake the tag. Rough handling can break internal circuit boardsDo not use harsh chemicals, cleaning solvents, or strong detergents to clean the tagDo not paint the tag. Paint can clog the moving parts, affect the radio communication and prevent proper operationUse a soft, clean and dry cloth to clean the tagUse only the supplied antenna. Unauthorized antennas, modifications or attachments could damage the tag and may violate regulations governing radio devicesNOTEBatteries contain hazardous materials and should be disposed in accordance to disposal instructions
