Digi XBee® Cellular NB-IOT

Digi XBee smart modems offer the easiest way to integrate cellular connectivity into an OEM device or IoT gateway. 

 
  • Extremely low power consumption for battery life of 10+ years
  • Integrated MicroPython programmability
  • 90 days of free cellular service with development kits
  • Excellent coverage and building penetration
  • Enhanced with Digi TrustFence® security framework
  • CE/RED certified and network tested
  • Manage and configure with XCTU and Digi Remote Manager®
  • Transparent and API modes simplify software integration
  • Reduced hardware complexity with only 1 antenna required

Digi XBee Cellular smart modems were specifically designed to accelerate time to market for OEMs or solution providers adding cellular technology to their products. The modems are end-device certified, so there is no need to go through the costly and lengthy FCC or carrier end-device certifications. The software integration is simplified by using Digi’s straightforward and flexible API.

NB-IoT, part of 3GPP’s release 13, is designed to address the growing demand for low power, low cost applications. NB-IoT supports a new power saving mode which extends sleep time and extends battery life. It is ideally suited for applications with very low data usage (typically <1MB per month), where low latency is not critical.

With the suite of standard XBee API frames and AT commands, existing Digi XBee customers can seamlessly transition to this new modem with only minor software adjustments. When OEMs add the Digi XBee Cellular to their design, they create a future-proof design with flexibility to switch between wireless protocols or frequencies as needed, ideal for any business with an agile roadmap.

Like all Digi products, customers can manage all of their wireless devices with Digi Remote Manager®. The XBee Cellular can also be bundled with a cellular data plan and SIM, eliminating the hassle of securing and managing carrier data plans.

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.
