Chapter 1. Introduction
1 Introduction
The Ekahau A4 Wi-Fi tag is part of Ekahau RTLS (Ekahau Real-Time Location System) that consists
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 Level
This User Guide documents the functionality available with software release level, 1.0.
1.2 Features of A4
The following features are included with this software release:
●
●
●
●
●
●
●
●
●
●
●

used such as for maintenance
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
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 Controller.

Chapter 2. Tag Operation
2 Tag Operation
2.1 Button Activated Location Update and Maintenance
Call
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, if White button 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 Settings
The Ekahau A4 tag can be reset to factory settings by using a button sequence as follows:
1.
2.
3.
4.
Press and hold the White button until Left LED flashes orange. If the tag is busy tvvhis 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 the White button is pressed.
Do not mind about this and keep on pressing the White button until the Left LED flashes
orange.
When the Left LED flashes orange, immediately press down the Blue button.
After approximately 2 seconds both LED’s flash orange.
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 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 50 % 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
A4 firmware update requires a new UDP port allocation from EPE (defaults to 8563). See “Global
Settings” page in EPE Config Utility.
Chapter 2. Tag Operation
2.4 Optimizing Battery Life
The 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 and tag configuration 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.
A4 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.
2.5 Turning off the A4 Tag
The 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.

3.3 Battery Replacement
Figure 3.1. Battery polarity and replacement
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 1 minute
Chapter 3. Technical specifications
waiting 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.
Recommendations for choosing and replacing batteries:
●
●
●
●
Use always new batteries
Replace both batteries at the same time
Use only 3.0V, CR2 size batteries
Ekahau recommends batteries from Duracell, Maxell, Sanyo or Varta
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 minerals 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 temperature 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 devices
