US carrier AT&T has completed deployment of its nationwide LTE-M network ahead of schedule to enable a new generation of Internet of Things (IoT) devices and applications. The LTE-M network is now live across the U.S. on operator's nationwide 4G LTE network, following software upgrades. 

AT&T plans to deploy LTE-M across Mexico by the end of 2017 to create a North American LTE-M footprint covering 400 million people.

Operator's LTE-M deployment marks another step forward on its path to 5G and massive IoT. And the network is deployed with global, 3GPP standardized technology using licensed spectrum for carrier-grade security.

Operator is also launching a full new suite of rate plans with LTE-M, with monthly plans starting for as little as $1.50 per month per device. Further discounts will be available for yearly and multi-year plans, as well as volume commitments.  LTE-M modules will be available from it's supplier for as low as $7.50 each, including a SIM card. 

Advantages of LTE-M over traditional IoT connectivity options include:

• 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).
• LTE-M supports large-scale IoT deployments such as smart city services, smart metering, asset tracking, supply chain management, security and alarm monitoring and personal wearables. It has been embraced by leading global carriers. That helps build a broad base of ecosystem partners, devices and applications for global markets.
