1. Introduction
Mastiff™ Tag is an active RFID tag ideal for locating and monitoring people inside the
buildings or in outdoors. This can be used across schools, colleges, hospitals, offices to locate and
monitor students, employees, support staff, contract workers, visitors etc.
It sends the address of the tag at periodic intervals which can be captured by a compatible
active Mastiff Active RFID reader. The tag comes along with custom software through which the
settings can be changed wirelessly. The in-built memory stores the modified settings and the
settings can be changed multiple times without any restrictions. The tag design has been
optimized for very low power consumption, so to give higher battery life of around 5 years with
its 1000 mAH battery.
The size of the tag almost matches the dimensions of a typical credit card but the thickness is
around 5 mm. The tag is completely sealed with IP67 ABS plastic enclosure which protects it
against dust and water. The tag is light-weight and it can be easily connected through a string like
a normal ID card.

The Mastiff Active RFID Tag is capable of operating in multiple frequency bands such as
865-867 MHz in India, 868-870 MHz for Europe and 902-928 MHz in North America with a single
hardware design. But the frequency bands are pre-programmed and the users are allowed to
choose a particular channel within the set frequency band. The tag operates through a 3V lithium
MnO2 battery with 1000 mAH capacity. The battery power can typically last for 5 years when
operated at ideal conditions.
The RF transceiver is capable of operating as transmitter and receiver. Once programmed,
the tag acts as a transmitter sending the signals at a pre-defined time interval. The typical data
transmitted are its unique address and low battery indication. The low battery indication is
triggered when the battery voltage drops below 2.2V. The battery can last for 1 to 2 months after
the low battery indication is triggered. The low battery indication captured by the reader will be
given out to the server which enables the users to take appropriate action.
The reed switch in the tag is used to change the battery from normal working mode to
configuration mode. The settings of the tag can be changed through custom software during the
configuration mode. More information on device configuration can be found in the section ‘5.
Device Configuration’. The device settings are stored inside the internal memory of the tag. The
tag comes with an optional internal clock for automatic wake-up and to perform other time
driven activities.

4. Functional Flow Diagram
When the reed switch in the RFID tag is activated through a magnet, the RFID tag starts
transmitting the current configuration data. The data is displayed in the ‘Read Configuration
Settings’of RF Tag User Configuration Utility software. Also the ‘Write to Device’button is
enabled for 20 Seconds for the user to write the configuration data. To avoid the time delay, users
are advised to enter the new data in the screen before activating the reed switch in the RFID Tag.
The RFID tag will wait only for 20 sec to receive the configuration settings from the USB dongle.

5. Device Configuration
5.1. Overview
The user configuration utility software is an effective tool to program the settings of the
tag besides testing some of the features of the tag. It’s is a simple and easy to use tool which is
used to program the settings. It requires a USB dongle which acts as an interface device between
the software and the tag to read and update the settings.
The software can be used to read the settings of the tag as well as to write the settings.
During the operation which writes the settings to the tag, the tag needs to be first activated by a
magnet to convert it into configuration mode. The data to be written is then given to the USB
dongle based on user input. The USB dongle sends the data wirelessly to the tag. An
acknowledgment and new settings are sent by the tag once the data is successfully written. The
new settings are refreshed in the software indicating a successfully update.
Since there can be multiple users trying to program the tag, the distance between the USB
dongle and the tag must be maintained less than 30 cms.

5.2. How to Use the Software
The tag user configuration utility software is easy to use custom software which is used to
program the settings. The software is easy to use and it’s self-explanatory.
Figure 3: Screen Shot of User Configuration Software
The user configuration utility software allows the users to create/modify certain
important settings of the tag during installation. This flexibility will allow the tag to operate in
different frequency channels and various RF baud rates and transmit power levels. RF baud rate
and power levels have a direct bearing on the wireless range covered by the tag.
The software is capable to program the following settings:
