EVOLUTION OF PUSH-TO-TALK OVER LMR
LMR PTT - narrowband voice, very low speed data,
ruggedized but expensive devices, with limited connectivity
§  1980s – PTT over trunked LMR systems (i.e. Smartnet®)
§  1990s – PTT over digital LMR systems (i.e. EDACS®)
§  2000s – Project 25 makes multi-vendor PTT possible
§  2010s – PTT over 6.25kHz with P25 Phase 2

EVOLUTION OF PUSH-TO-TALK OVER CELLULAR
Cellular PTT - broadband voice/high speed data, lower cost devices,
significantly better connectivity, lacks mission critical calling capabilities
1990s – introduction of PTT over iDEN
§  Early 2000s – proprietary push-to-talk over 2.5G/3G
§ 
Mid 2000s – first OMA PoC standard – V1.0
§  Late 2000s – OMA PoC V2.0 standard
§ 
§ 
2010s – OMA PoC V2.1 defines functionality for critical communication

USER IMPACT
§  Convergence of commercial and public safety PTT on one
technology – LTE
§  One global standard for RAN and PTT for both business and
public safety
§ 
§ 
§ 
§ 
§ 
Higher volume and lower cost
More choice of devices and device types
More innovation, faster – easy migration to 5G
Inherent interoperability
No vendor “lock in”
