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

LPWA

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

It takes a multi-network strategy to serve the Internet of Things most efficiently

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

Fringe Area Coverage

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.

3G Network Longevity, 3G Module and Device

CertificationAT&T has not made any public announcements related to the longevity of the 3G networkWe share

3G Longevity language with partners under NDA (No recent changes)

No new

3G modules

to enter

the AT&T lab for

approval as of the end of 2016Applies to 3G only and 2G/3G modules. Modules with LTE are not affected.MR’s to existing already approved modules will continue to be allowedNo new 3G devices may enter the AT&T lab after 6/30/2017Applies to 3G only and 2G/3G based devices. Devices with LTE are not affected.MRs to existing already approved devices will continue to be allowed.Slide11

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)
