Digi XBee® Cellular LTE-M

Digi XBee Cellular LTE-M embedded modems provide OEMs with a simple way to integrate low-power cellular connectivity into their devices.

 
  • Development kits and modems shipping October 2017
  • FCC certified and carrier end-device certified
  • Excellent coverage and building penetration
  • Digi XBee Transparent and API modes simplify design
  • Low power consumption optimized for long battery life
  • Reduced hardware complexity with only 1 antenna required
  • Integrated MicroPython programmability enables custom scripting directly on the modem
  • Enhanced with Digi TrustFence™ security framework
  • Manage and configure with XCTU and Digi Remote Manager®
  • Available with Digi provided SIM cards and data plans

LTE-M, part of 3GPP’s release 13, is designed to address a growing demand in the IoT community for low-power, long-range options for IoT devices. Two new key features included in the LTE-M specification include;

  • LTE eDRX (Extended Discontinuous Reception) – Increases the length of time an LTE-M device can sleep in between ‘check-ins’ with the LTE network.
  • LTE PSM (Power Saving Mode) – LTE-M device notifies the network that it is going to sleep indefinitely. When the device wakes up, it can transmit data, then will remain in idle Rx mode for at least 4 frames, then it can go back to sleep indefinitely. LTE-M devices using PSM that transmit once per day should see battery life in the 5-10 year range on simple AA batteries.

The Digi XBee Cellular LTE-M is a low-cost, low power wide area (LPWA) embedded cellular modem. It is FCC and carrier end-device certified which completely eliminates the cost, complexity, and risk involved in the certification process. The modem is programmable, with support for custom MicroPython applications running directly onboard, allowing users to more efficiently manage their devices and eliminating the need for an external microcontroller in certain use-cases. It includes the full suite of standard XBee API frames and AT commands, so existing customers can drop this modem into their existing designs to instantly achieve cellular integration, without the pain and hassle of doing a complete re-design.

Build for today. We have you covered for tomorrow.

Digi XBee modems are pin compatible and ready for emerging IoT networks.

What’s in the Digi XBee Cellular Development Kit?

  • Digi XBee Cellular embedded modem
  • 1 Digi XBee development board
  • 1 SIM
  • 6 months of free cellular service (5MB/Month)
  • Antennas and power supply

If only one antenna is used, will the Digi XBee Cellular modem still be carrier end-device certified?

Yes. The modem has been certified for both single and dual antenna configurations. More information on antenna specification requirements can be found in the User Guide.

The development kit includes 6 months of free cellular data service. How much data can I use per month? How many SMS messages can be used per month?

6 months of free cellular service will be limited to 5MB/month and recommended to use 100 SMS per month or less. The kit is for testing purposes only, not for production.

What happens if a customer goes over the set data limits (5MB)?

If only over by a little (1-2MB), nothing. If over by 10MB in a given month, customer will be contacted by Digi to determine if a larger plan is required.

Can customers provide their own SIM for testing purposes?

Yes, they can use their own SIM if they prefer.

Does a customer need to purchase a support plan to get help with technical questions when evaluating a kit?

No purchase required, free base email support is available for customers evaluating product with a development kit.

Does Digi XBee Cellular have GPS capabilities?

No, GPS is not supported on the modem.

Is Digi XBee Cellular a drop-in replacement for other Digi XBee modules?

Yes, but customers need to evaluate the power supply of their designs to verify that they can support peak transmit currents up to 1A, which is required for all LTE CAT 1 cellular radios.

How long does it take the module to wake up from Deep Sleep and start communicating over the cellular network?

It takes about 20-30 seconds to wake up and begin transmitting over the network.

What is the difference between Transparent Mode and Bypass Mode?

Transparent Mode acts as a serial line replacement. The device queues all serial data it receives through the DIN pin for RF transmission. When a device receives RF data, it sends the data out through the DOUT pin.

In Bypass mode, the device acts as a serial line replacement directly to the cellular component. In this mode, Digi XBee Cellular Modem exposes all control of the cellular components AT port through the UART.

What is the difference between Digi XBee Cellular and NimbeLink?

A cellular breakout board like NimbeLink will include the cellular module, and may add end-device certification, a SIM slot, and a simple power supply and antenna connector. The Digi XBee Cellular hardware is fully integrated with an on-board cellular module, ARM Cortex M3 microcontroller, power regulator, and security chip, all packed into the small 24.4 x 32.9mm XBee through-hole footprint. This enables a number of useful features on Digi XBee Cellular that are not available on breakout boards like Nimbelink, including the Digi XBee software interface, critical security features, sleep modes, and on-board programmability to name a few.
