A Better Understanding of the Narrowbanding
Mandate through a Public Safety Radio Study
“Lincoln County selected GeoComm to complete an in-depth analysis of our existing radio
systems. We requested they provide us with options and recommendations on how we could
comply with the upcoming Narrowbanding mandate. After thoroughly reviewing our system and
visiting with our responders, GeoComm’s staff provided us with a detailed report evaluating our
current system as well as options and recommendations on how we can migrate our system to a
Narrowband mode of operation.”

The upcoming Narrowbanding mandate brings a new set of regulations that
may affect your public safety radio system. To comply with the deadline,
many agencies are asking what their best approach is to meet all of the
requirements.
To begin the process of complying with this mandate, Lincoln County,
Washington first looked at the different aspects of their current public safety
radio system. It was their hope that by examining the entire system they
would have a clearer path to improving their current interoperability issues
and a plan to comply with the FCC Narrowband Mandate. Additionally, the
county wanted to identify the steps beyond narrowbanding they could take
to modernize and upgrade their radio systems. Included within their project
scope was an incremental roadmap that would aid in improving their radio
system from where it was into the future of digital and regionally
interoperable Public Safety radio systems. Lincoln County requested help
from GeoComm to determine all of the steps needed to achieve these goals.
GeoComm’s study of the current system included reviewing the equipment
used in the county, a review of the different radio channels being used, and a
review of the coverage that was currently achieved by the equipment.
The equipment review identified the strengths and weaknesses that existed
in approximately 600 pieces of radio equipment. From this equipment
review, an assessment was created that outlined the communication
infrastructure the county had in place and aided in determining if the
equipment was compatible with the requirements for a Narrowband mode of
operation. The current radio channels Lincoln County used was also
reviewed to determine the strengths and weaknesses in the existing
system. The technical information that was gathered in reference to the
radio channels was compared to the county’s operating procedures which
aided in providing recommendations for system improvements. In addition,
the performance levels that the current radio system achieved was
compared to the performance levels required to ensure adequate public
safety response. This was reviewed to help alleviate the current spotty
coverage the county was experiencing.

Lincoln County’s public safety radio study examined their current and future
mobile and portable coverage expectations. As a result of the study, the
GeoComm project team provided recommended steps the county could take
to improve regional interoperability and convert their radio system to comply
with the Narrowband Mandate. Lincoln County no longer has to wonder how
this new set of FCC regulations will affect them; they have a complete set of
options including system upgrades and improvements outlining what they
need to complete in order to meet the mandate.
