DATA BECOMES CRITICAL
Will you rely on a video transmission to the Control Center instead a radio call in the critical moment?
Probably not today. But this is about to change. Teltronic is leveraging his vast experience as a PMR supplier
to provide a LTE solution which is tailor-made for Public Safety: evolved NEBULA is fully compliant with
3GPP standards but complemented with those services that are mandatory for mission critical networks.

THE BEST OF TWO WORLDS...
Your narrowband TETRA or P25 network can be the first and most important building block of your brandnew broadband LTE solution. Take advantage of a proven availability and an unbeatable coverage footprint
to incorporate the broadband network with an advanced control channel: your narrowband system. Your
Network Operation Centre will know always whether or not LTE coverage is present on a remote user, and
will be able to choose the available wireless system to deliver the message.

...IN A SINGLE NETWORK EXPERIENCE
Teltronic’s Broadband PMR Solution is pricewise. Your network will share most of the components and the
know-how-to-operate with the narrowband solution. That will just boost the OPEX optimization providing
an easier RoI (Return of Investment) over the operational years.
The Evolved NEBULA system has been designed to maximize the flexibility in the deployment, for both small and
large networks. Evolved System Control Nodes are able to provide full switching capabilities for small and medium
networks; a higher level switch (SIS) may be introduced in larger networks to optimize bandwidth in the different
network regions, which is critical for LTE systems.
eSCN: the Evolved System Control Node provides Switching functions for both LTE and TETRA. In case of LTE it can
feature all modules of the EPC or part of them, in case a higher hierarchy switch (SIS) is available.
SIS: for large networks it is always advisable a “divide and conquer” policy. This is especially important in LTE,
where required bandwidths are much more higher than in narrowband systems. The Segments Interconnection
Server, enables connectivity between regional LTE + TETRA Switches, providing higher reliability and bandwidth
optimization.
BSs: eNEBULA features different kind of base stations. TETRA only Site Base Stations (SBS), or mixed TETRA +
LTE ones, called eSBS in different formats and capacities. An outdoor eNodeB is also available providing LTE-only
coverage.
eNMS: one of the main advantages of the Evolved NEBULA system is that LTE and TETRA technology shares most of
the hardware, controllers, routers plus the management of the system and their subscribers in managed from an
unified Network Management Software, the Evolved NMS.
… built only for Critical Networks, the network
that will be there when really matters…
