safety
We live in a changing world, where public safety and the owners and operators of
critical infrastructure must address new threats and challenges, both natural and
man-made. In addition to police, fire and emergency medical services (EMS), utili-
ties and transportation agencies have critical roles to play in emergency response.
It’s no longer enough for these first responders to rely on a push-to-talk (PTT)
network for situational awareness.
Mobile technology capable of sending and receiving bandwidth-intensive data
can help emergency response organizations do their jobs more effectively and safely.
These organizations need mobile broadband networks that let them share streaming
real-time video, detailed maps and blueprints, high-resolution photographs and other
files that today’s public safety wireless networks can’t handle. The same is true when
served by commerical wireless networks during major events or catastrophes.
Long Term Evolution (LTE), the new standard for wireless communication of
high-speed data for mobile phones and data terminals, will satisfy the broadband

radio access networks, which sit
between mobile devices – such
as cell phones, tablets and laptops – and the core network. As the name implies,
LTE encompasses the evolutionary path from today’s networks to tomorrow’s all-IP
based, ultra-fast converged networks. It enables real-time video transmission from
a firefighter at an incident scene to the emergency operations center, transmission
of high-definition video (some of which may be received through next-generation
112/911 systems), distribution of high-resolution photos and detailed maps to police
cars, and much more. LTE gives users the same experience in a mobile setting as on
fixed networks in the workplace or home.
LTE provides unprecedented capabilities for mobile broadband networks. It has
been declared by public safety and communications experts to be the technology of
choice for mobile broadband communications for years to come.
limitations of first Responder communications
Current Land Mobile Radio (LMR) and Professional Mobile Radio (PMR) networks
are limited by their lack of capacity and standardization, which prevents emergen-
cy response teams from communicating in an efficient and cost-effective manner.
No mission-critical broadband: LMR/PMR networks rely on narrowband systems

Lte has been endorsed by major public safety organizations as the technology of
choice for the public safety broadband network. Proponents include:
• Association of Public-Safety communications officials (APco)
• tetRA + critical communications Association (tccA)
• international Association of chiefs of Police (iAcP)
• international Association of Fire chiefs (iAFc)
• united States National Public Safety telecommunications council (NPStc)
that are optimized for voice. They lack the capacity to support rich, multimedia
content, which is needed to improve response and cooperation among emergency
response organizations. While some public safety agencies have low-rate wide-
band data capabilities, most do not. Video and bulk file transfers are impossible
with most public safety mobile data networks, and support for remote access
to databases and Internet is limited. Some agencies pay for broadband through
commercial providers, which allows them to have access to the Web and e-mail,
for example. However, these networks become congested during catastrophes,
emergencies or other public safety events, which is exactly when public safety
communication is most critical.
No interoperability: While efforts are underway to standardize LMR/PMR net-
works using APCO Project 25 (P25) and TETRA open standards, many LMR/PMR
systems rely on outdated proprietary technology and hence do not interoperate.
This hampers inter-agency response because LMR/PMR systems used by neigh-
boring cities or counties cannot communicate with each other. The problem is fur-
ther compounded when a multi-agency or joint public safety and utility response
is required. An agency could operate multiple dedicated networks to cater to its
voice and data needs, though this would multiply deployment and management
costs: each time a change is made to a network there are new costs for equipment,
testing, operations and devices.

unprecedented Opportunities
In contrast to existing technologies, LTE provides massive capacity and low
latency, ensuring the necessary broadband to support mission-critical applications.
It is a standards-based technology which ensures interoperability and cooperation
among agencies. As a global mobile technology, it inherently supports roaming.
Furthermore, LTE leverages a large competitive ecosystem of equipment, applica-
tions and devices made for the private (commercial) sector, which can mean lower
development and equipment costs.

lte benefits fOR Public safety – an OVeRVieW
Lte is a powerful new technology that will benefit public safety in numerous ways
Greater interoperability and enhanced inter-agency cooperation:
• Standardized protocols and interfaces
• Built-in roaming capabilities
• Sophisticated quality of service (QoS) toolbox including priority access
mechanisms that authorize and prioritize communication, and provide
guaranteed and differentiated QoS applications
unprecedented broadband capabilities:
• High capacity, allowing a wide variety of applications that rely on rich,
multimedia content
• Low latency, enabling real-time services (VoiP, video, group calls)
• Much faster than 3G, employing advanced technologies
cost effective:
• Lowers operating costs with a simplified all-iP architecture
• Leverages a rich, open ecosystem from commercial networks
• complements existing narrowband radio networks
• Makes private networks more economically feasible
High reliability and security:
• Supports a geographically redundant iP-based architecture, reducing single
points of failure
• Supports encryption/ciphering on both control and user planes, enabling secure
communications
evolution to mission-critical network:
• 3GPP is incorporating enhanced functionality to support features required for a
mission-critical network in the upcoming release (Release 12) such as:
¬ ProSe (Proximity Services) for direct mode operation
(also called talk around) between terminals
¬ enablers for efficient group communications (GcSeL)
