LPWA networks are optimized for IoT and address key challenges of diverse use cases
Key Customer BenefitsCoverage ExtensionLonger battery lifeLower cost of hardware and service
AT&T IoT Connectivity: Low-Power Wide-Area Networks
LPWANs are either Licensed or Unlicensed
Licensed leverages managed spectrum with existing cellular standards
Unlicensed uses unmanaged spectrum and proprietary or open-source standards.
LTE-M
(also known as Category-M1) is a licensed evolution of LTE specifically built for IoT devices.AT&T will be deployed network-wide with LTE-M by the end of 2Q 2017, coverage in Mexico by end of 2017AT&T in combined press release with 9 other global Mobile Network Operators stating support for LTE-M KDDI (Japan), KPN (Netherlands), NTT DOCOMO (Japan), Orange (29 countries), Telefonica (Europe), Telstra (Australia), TELUS (Canada) Slide3

LTE-M:
IoT-optimized cellular enables lower cost with moderate throughput
NB-IoT:
Potential for even lower module costs with less mobility support and lower throughput. AT&T intent to deploy NB-IoT still TBD. Will conduct trials to better understand the technology.
Key variants and options
Optimized for IoT
Lower cost modems
Longer battery life
Extended coverage for indoor and underground penetration
Greater coverage, roaming, security, and reliability than unlicensed alternatives

LTE-M Application Use CasesSlide7
Coverage up to 7X greater than standard LTE*
Better service in-building to reach devices behind thick walls or deep in a basement
Signal reaches subterranean for devices underground

LTE-M Feature: Coverage Enhancement
Standard LTE
LTE-M
*Coverage will vary by application and does not indicate an expanded radio frequency footprint. Available June 2017Slide8
8
*Based on 3GPP reference model estimatesPower Saving Mode (PSM): allows the device to enter extended “sleep” periods.
Extended Discontinuous Reception (eDRX):
allows for the device to extend the time interval in which it will listen for synchronization messages from the network
Net Benefit:
Both of these features together can
extend battery life
to 10+ years LTE-M Feature: Long Battery LifeSlide9
LTE-M modules approved for AT&T will be available from the following suppliers within 2017.
Most LTE Only, some with international roamingSome modules with 2G fall back
LTE-M Starter Kit (radio shield) upgrade to initial AT&T Starter Kit should be available AT&T negotiating with several of these partners for a very attractive LTE-M module offer within 2017.There will be multiple opportunities targeted below $10, volume will drive LTE-M module prices lowerSome new LTE-M chipsets will incorporate the SIM directly into the silicon to further lower the cost and size (technically referred to as the I-UICC). Provisioning/manufacturing present same logistical challenges as embedded SIM which is also an alternative.

VoLTE Provisioning capability is dependent on
UICC (SIM), MSISDN (phone number), and management platform (AT&T Control Center, AT&T Enterprise On-Demand, etc)
Enterprise On-Demand customers are being converted to AT&T Control Center (“ACC-410” also known internal to AT&T as CCIP) while maintaining their same UICC (known as 310-410)
