The Basics

The most critical aspect at the heart of any IoT device is its wireless (RF) communication capability.

In choosing an AT&T Approved Module, developers must consider the ability or need to handle:

  • Network transitions and varying radio conditions
  • Latency
  • Authentication and network security
  • Transitions from data-only to data/voice
  • Battery consumption and battery usage needs
  • Resending of service requests following a request rejection or denial

Take Advantage of AT&T Resources to Make the Best Decisions on Your Module.

  • Choosing a module from the AT&T Module Catalog saves time, while assuring ongoing network compatibility. See our AT&T IoT Technology Roadmap.

  • If you’re a module developer, AT&T’s ADAPT program is the fast track to certification of newly developed LTE-capable chipsets. Find our list of chipsets under the ADAPT chipset tab on the module catalog.

  • AT&T’s IoT Accelerator Program is the most efficient way to accelerate IoT device development; and implementation is through a selection of low-cost, high performance modules. AT&T has made it quick, easy and economical to obtain these modules by offering them through key suppliers for as low as $7.50 each. Nobody accelerates IoT like AT&T.

  • The final step in the development process is testing and certification. Go to Get Get Network Ready to learn about the simple steps required to get a device certified.

A Word of Caution Regarding Chipset Design.

Chipsets are the building blocks for every wireless device but building a wireless radio at the chipset level is difficult and costly.  Every AT&T Approved module contains an AT&T Validated chipset at its core.   Rather than attempt to design your own chipset based device design, and pay a $50,000 fee for AT&T to ensure that it works on our network (and additional 3rd party charges to achieve certification), we encourage you to use an existing AT&T approved module.
