Proposal Summary


Develop a national baseline of public safety
requirements for LTE

local, state and federal.


Test interoperability of multiple vendors’ products


12 base station sites available


Up to 6 vendors supply eNodeB base stations


Initially, use vendors’ remote core networks (Evolved Packet
Core
-

EPC) and prototype devices


Develop multiple testing phases


Test interoperability of public safety applications


Test vendor interoperability of LTE network elements


Evaluate Radio Access Network (RAN) design &
performance

Public safety (local, state & federal) has unique
interoperability challenges (roaming, applications, VPNs,
etc.)


LTE is highly complex to build and operate, especially
the core network


Testing is a driver of ongoing public safety requirements,
especially for devices


Mitigate risks of new technology


Develop local/state/federal public safety
-
driven design
and cost modeling for LTE


Opportunity for public safety leveraged network with
commercial carrier(s) depends on architectural design
and business process development

Why Public Safety Needs a Test Facility
