LMR/LTE INTEGRATIONPS IoT

DECEMBER 14, 2017

The problem• FirstNet promises to provide a

nationwide public safety broadband network using LTE technology

• Voice communication is the primary method in which first responders communicate

• Current commercial-grade push-to-talk (PTT) technology does not meet the needs of first responders

• Current PTT solutions are proprietary

3

The solutions• National Public Safety

Telecommunications Council (NPSTC) established a broadband working group to identify gaps between current commercial PTT technology and “mission critical” grade based on LMR technology

• Resulted in the following requirements:

– Direct or talk around– Push-to-talk– Full duplex voice systems– Group call– Talker identification– Emergency alerting– Audio quality

4

What happens next?• The 3rd Generation Partnership Project

(3GPP) is the global standards development body responsible for the LTE standard

• 3GPP adopted the NPSTCs recommendations and is currently implementing these features into the LTE standard

• Once a 3GPP standard is developed manufacturers will implement it based on their expectations of profitability of their effort

5

ProgressNPSTC recommendations now become standard development efforts. Among the most important examples are:

• Proximity Services (ProSe) – Discovery of units in close proximity and facilitation of direct communications

• Mission Critical PTT – Standardized PTT capability that addresses call types, floor control, priority, preemption, performance, group management, off-network use, security, interworking with non-LTE PTT systems

6

What’s available today?

• Push-to-talk over Cellular (PTToC) is the pre-MCPTT solution that is currently widely available

• These are mostly “over the top” apps

– “Over the top” apps are treated by the carrier networks as regular Internet traffic with no special considerations

– Integrated apps are closely integrated with the carrier networks and thus have more control and advanced features

• Many providers integrating with public safety LMR systems

7

The market• Radio system-centric PTT providers

– Harris BeON– Motorola WAVE

• Carrier-integrated PTT

– AT&T Enhanced PTT (Kodiak)– Sprint Direct Connect (Kodiak)– Verizon PTT+ (Kodiak)

• Network agnostic

– ESChat

8

Benefits• Extend radio system channels to

commercial networks:

– Operation outside jurisdiction– Operation where LMR coverage is

insufficient– Operation in-building on WiFi

networks• Provide radio system access via

smartphones for management personnel or interoperability with public safety:

– Saves cost of radio for non-Mission Critical users

– Allows monitoring and participation in events when outside of the jurisdiction

• In-app GPS location

LMR integration

• IP Gateway

– Donor radio for each channel to pull audio

– Gateway interfaces radio channel audio to the application host

– Good for small-scale deployments

– Emergencies and IDs do not extend from PTT apps to radio system

• Inter-RF Sub System Interface (ISSI)

– Uses P25 standard for inter-system communications

– Scalable for many talk groups without additional equipment

– Extends IDs and emergencies to PTT app users

– High cost for P25 system licenses

Device integration• Harris XL200P

– BeON Integrated with standard LMR radio, accessible via talkgroupposition

– Compatible on WiFi, Verizon LTE, and Band 14 (FirstNet) networks (not yet certified by NTIA or AT&T)

• Motorola

– Working on LTE integration via speaker microphones

– Compatible with fielded radios via software upgrades

What’s to come?• Kodiak – AT&T’s PTT provider, recently

purchased by Motorola

• AT&T will integrate the 3GPP MCPTT into the FirstNet core by March 2020; Mission Critical voice/data by March 2019

• Expect PTToC providers to adopt MCPTT standard as FirstNet becomes available and driven by market demands

14

What’s to come?• MCPTT applications will run on FirstNet

in limited-use scenarios similar to current PTToC deployments

• MCPTT device market will continue to mature (more providers, more options, more competition)

• Early adopters may begin migrating primary voice communications when and where FirstNet meets coverage, capacity, and reliability requirements and if justified by cost model

15

Conclusions• FirstNet is planning to support voice communications and

standards developed to support those communications, with implementation of those standards scheduled.

• Proprietary PTT solutions are available today that leverage commercial networks and can provide some immediate benefits. Given that MCPTT standard will be available in about two years no long-term commitment to proprietary makes sense.

• Continue to invest in LMR. There is no realistic timetable for when FirstNet will provide a reasonable replacement. Constraints are the five year FirstNet deployment schedule, uncertainty about in-building coverage, and operating costs. But, with the current high price for P-25 devices and networks a careful financial and functional analysis is required.

Internet of Things Universe

The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
