The Otiom technology

If it becomes necessary, Otiom can locate a person. Otiom’s specially-developed antenna lets you find someone with dementia even if they are in wet environments. For example, in rain or in a ditch.


The battery life of the Otiom-tag.

The battery life of the Otiom-tag is up to one month under normal usage.

Normal usage means that the person with the tag stays mostly in the vicinity of his/her home, with up to 30 minutes daily movement outside the home – without triggering the Otiom alarm.

Otiom saves power when inside the home. ‘Home’ means that the tag is connected to the Otiom Home Base. The Home Base is included when you buy Otiom. It has a range of about 145 m2, takes up just 6 x 2.5 cm and is wireless.

The Otiom-tag uses more battery power when it is outside the home for a prolonged period of time. For example, if the person goes for a walk for up to three hours a day, the battery life will be reduced to about one week.

If the Otiom-tag triggers an alarm, the battery life will be reduced further. Otiom triggers an alarm when the person with the tag leaves the established safe zone.

Otiom automatically sends a text message when the Otiom-tag’s battery level reaches 30%.

The battery life of the Home Base is 3-4 years.

Otiom’s technology.


The primary technology in the Otiom-tag is Narrowband – Internet of Things (NB-IoT). NB-IoT is a Low Power Wide Area Network, which was developed to make electronic communication more effective, extend battery life and provide better coverage – even indoors. NB-IoT is designed to send small data quantities, e.g. location notifications.

NB-IoT uses mobile phone masts to communicate. This ensures a very strong signal with good coverage, both indoors and outdoors. It means that, in general, Otiom will still have a connection in situations where a GPS device will not work and where the signal is too weak for a phone conversation. The small data quantities and the strong signal means that Otiom uses far less power than a GPS device, for example.


The Otiom-tag and Otiom Home Base include Bluetooth 5.X technology. Bluetooth has an incredibly low power consumption. It is used when the Otiom-tag and Otiom Home Base communicate as well as when you define the home zone. This means that if the person with dementia never leaves the home zone – for example at a nursing home – then the Otiom-tag can have enough power for several months.


The Otiom-tag also uses Global Navigation Satellite System (GNSS) to determine outdoor locations. GNSS includes a large network of satellite systems from many different countries, including GPS, GLONASS, Galileo and Bedou. The GNSS system is used to determine positions within a few metres. The GNSS antenna in Otiom is specially-designed for great precision with very low power usage. It is therefore a great extra safety measure.
