n considering LTE, and how
it could change the way that
operators deliver mission
critical communications, we
need to take a step back and
look at what LTE really means.
LTE is the first technology since
the emergence of TETRA/ P25/
Tetrapol that is considered/
deemed capable of delivering
the future functionality of the
emergency services.
What do I mean by that? Well,
TETRA has a very fast call set up

mobile phone, you typically would

number, press the green button, wait

times are inherent to the emergency
service requirements. LTE is the first
technology since the development
of TETRA that has the core building
blocks that will enable those fast
