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 chipset tab on the module catalog database.

  • 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 Network Ready to learn about the simple steps required to get a device certified.


A Word of Caution Regarding Chipset Design.

The chipset is at the heart of any module — use the right one and your device will work consistently, use the wrong one, and it may be hard to diagnose and be costly to repair. Rather than attempt your own chipset level design, and risk up to a $175,000 fee for AT&T to remedy a faulty design, we encourage using an existing, validated chipset.
