communication over LTE
Since LTE enables prioritisation of mission
critical communication vis-à-vis other data
technologies, it is best suited to meet the
needs of public safety. This is being built
into the standardization of LTE.

LTE is the globally adopted latest mobile
broadband technology. It is the most
logical technology choice, if public safety
communities want to benefit from the
latest radio performance as well as
economy of scale.
LTE fulfills the below public
safety requirements:
1. Mobile broadband throughput and
capacity for
a. Data apps with fast response times
b. Efficient uplink performance for e.g.
for multiple uplink video streams for
situational awareness
2. E2E security for
a. Application, network (e.g. FWs, IP
security), products
3. High availability for
a. Element resilience, system resilience,
load balancing and overload control,
resilient IP network (e.g. fast re-routing)
b. Isolated operation
4. Deployable systems for
a. Communication coverage anywhere
(cells installed in PS vehicles, trailer
system)
b. Standalone systems, satellite
connectivity
5. Prioritisation and QoS
a. Prioritisation of public safety

It is this need for enhanced
communication features that is driving
public safety organisations to deploy
LTE-based communication systems.
Usually a public safety organization
deploys a separate LTE-enabled system
initially for its mobile broadband
requirement. However, as the system
evolves, there is a strong need to
combine the traditional voice with the
LTE-enabled system.
For a Smart City & IoT: A
reliable public safety network is
an essential criterion for a city to
become a Smart City. In this regard,
an evolving public safety network will
not just enable various government
agencies to develop use cases as
per their unique requirements but
also take their city a step closer to
5G deployment in future. Further
with more and more devices being
connected and the ecosystem moving
towards Internet of Things (IoT), the
public safety system with LTE will form
a very important part of IoT in future.
The interoperability angle
However, lack of interoperability between
the traditional systems, like TETRA,
and LTE, is a limiting factor. The future
releases will have this interoperability
built-in enabling seamless handover
between these two technologies.
Although Nokia Networks is today
able to deliver end-to-end LTE network
solutions for public safety, the
capability will be further enhanced
with 3GPP public safety features from
