About UTC


UTC is the international association for the telecom and IT
interests of electric, gas and water utilities and other critical
infrastructure industries.


Formed in 1948, Based in Washington, DC


Membership includes all utilities, including investor
-
owned,
cooperatively organized and municipal
utilities.

Benefits of Sharing with Utilities

3


Utilities and Public Safety have similar communications
needs and are compatible users of the spectrum.


Utilities lack suitable spectrum to meet current and future
needs, but have access to other resources for broadband
network.


Utilities have partnered with public safety on both local and
statewide shared systems.


Partnerships create economies of scale and are spectrally
efficient, promoting international and national equipment
development.

Public Safety Broadband Network


LTE
and Prioritization


LTE currently supports nine Quality of Service (
QoS
) Class Identifiers (
QCI), which defines
if a “bearer” has a Guaranteed Bit Rate and also sets up the minimum queuing priority,
latency, and packet
-
loss attributes that the network must provide for each bearer, and an
application, device, or user may have multiple bearers established to carry the traffic
.


ARP defines the priority of the bearer and its susceptibility to pre
-
emption or whether or
not it can establish a connection to begin with. A bearer on a device or application (or
perhaps a user) can have either a very low priority or a very high priority. On a given
device it is possible to have a very high priority on a specific function (such as emergency
call) or very low, best effort (such as meter data). As a result, on the same device, it’s
possible to have 15 variations on a condition where critical data continues to flow while
non
-
critical data is rejected until the congestion clears
.


MBR and AMBR control the maximum bit rate of a bearer and can be used to scale back
the available bit rate that an application, device, or user is allowed under congestion
conditions. MBR is done “per bearer” for applications with a GBR while AMBR controls
the aggregate bit rate on a device for all applications without a GBR. These controls can
also be prior to congestion as a preventative measure to keep a high
-
priority user from
hogging all the bandwidth with, for example, a HD video
stream.

Public Safety Broadband Network


Governance


Some examples of utilities that share systems w/ public safety:


NV Energy, Nashville Electric Service, Nebraska Public Power District, and
Southern
Company


Governance based on cost
-
sharing principles and network
policies, including prioritization and network access.


Infrastructure available


utilities and public safety contribute infrastructure
Infrastructure

equipment


utilities and public safety contribute
equipment


Backhaul


utilities and public safety both contribute backhaul
equipment


End
point devices


mobile terminals, handheld radios, laptop network cards,
utility end points (each group maintains their own
end
-
point devices
)


Maintenance and Repair


utilities may provide these services and then share
the costs with public safety at the end of the year.


Governance models from these examples could be applied to
FirstNet
.


Utilities need representation on
FirstNet

and/or Advisory Committee.

Public Safety Broadband Network


Partnerships
and the RFP Process


Public Safety wants to partner with utilities.


Access to utility infrastructure and other resources


Interoperability during emergencies


Sustainability of the network from base of utility end
-
use devices


RFP process should provide meaningful opportunity for
utilities to participate.


Flexibility: multiple opportunities to bid on some or all of the
requirements in the RFP in a regional, state, local or tribal area.


Consistent w/ Spectrum Act provisions for “open, transparent
and competitive” RFP process.


Centralized process could discourage utility participation and limit
potential partners to a handful of nationwide commercial providers.
