The Network Technology Roadmap

The Network Technology Roadmap

All networks are not the same, so AT&T offers a multi-network approach to provide you with the dependability and flexibility needed to optimize your IoT solution. We began with supporting LTE-Category 3 in 2011, adding LTE-Category 1 in 2015, LTE-M in 2017, 5G mmWave in 2019, and now 5G sub-6 in 2020. AT&T continues to provide the latest in IoT network performance and capability. This network enables developers to use advanced modules that provide the basis for a new generation of devices, while lowering connectivity costs.

You can see on this chart how each evolutionary step allows us to decrease the downlink rate, cost and complexity.

Wireless Technology Timeline vs. Downlink Rate

*Downlink rates are theoretical maximum throughput.

Benefits of LTE-M:

• Longer battery life (expected up to 10 years)
• Better coverage for IoT devices underground and deep inside buildings
• Reduced module size (as small as 1/6 the size of current modules)
• Reduced module costs (as low as $7.50 for LTE-M)

Wireless Technology Comparison

Each solution brings you the carrier grade, multi-layered, and best-in-class security that you’ve come to expect from AT&T. This table will help you consider and compare the differentiating features of each network solution so you can make the best choice for your module and device.

*Individual performance may vary
**Requires support of Power Saving Mode (PSM) and/or eDRX
