Technologia LTE-M - SEZO AM

What is the LTE-M network?

LTE-M is a low-power broadband network specifically designed for IoT devices that can connect directly to 4G networks and, unlike LoRaWAN, without using a gateway.

An LTE-M-based system can support a wide range of mobile devices for a variety of purposes – from air quality sensors like SEZO AM, to security and medical devices.

How does the LTE-M network work?

LTE-M enables data rates of up to 1 Mbps and real-time communication, making it suitable for asset monitoring or real-time tracking, for example.

LTE-M provides global coverage, with the 2G network acting as a backup. The device connects to the cellular network – simply insert a SIM card from your carrier, just like a smartphone.

How long does the battery last?

Approximately 22 hours. It’s a rechargeable, non-replaceable battery. It can be charged using a wireless Qi charger.

How long does the wireless charging take?

Approximately 4 hours.  The device can be charged using a wireless Qi charger.

Is the charger included in the price?

No. It is possible to order the charger along with the devices through SEZO.

Is the device waterproof?

The device's case has an IP67 rating which means that the unit can be used in harsh outdoor environments. The standard warranty for the devices is 12 months from delivery. 

Does the location function work indoors?

The location based on GPS only works outdoors but the device records the last available location and also can send the information about the altitude of the device while the device is located indoors.

Thanks to defining the altitude we can define which floor is the device located on.

Can the sending interval be modified?

Yes, it is possible to manually modify the send interval directly through a data displaying platform. For details see User Manual sent along with the device.
