Sun Kwang Co Ltd began its container terminal operations in Incheon Southern
Port in 2005. By June 2015, it began expanding its services by constructing theSun Kwang Newport Container Terminal – SNCT at Incheon New Port.
Today, SNCT is widely recognised as one of the largest container terminals inIncheon Port in Korea, playing an essential role in handling the surging container
trade volumes with China and many other countries.

ABOUT SUN KWANG NEWPORT CONTAINER TERMINAL(SNCT)
SNCT is the largest container terminal in Incheon Port and ispart of Sun Kwang Co Ltd; it provides logistics, warehousing, andtransportation services for heavy cargo, metals, and container terminal
services in Korea.
SNCT operates seven quay cranes (STS) that load and unload
containers, 28-yard cranes (ARMG) to take containers in and out of theyard, and 40-yard tractors used for onboard operations and containertransportation in the 480,000 m² terminals.
SNCT handles up to 1.2 million TEUs annually and provides worldclass port logistics services to customers is its mission. An automatedoperating system manages all planning, fulfillment and work orders
related to container movement.

A TOP PRIORITY TO ELIMINATE THE NEED TO ELIMINATE
SAFETY RISKSINTERFERENCESIn February 2022, SNCT embarked on a bold
move to completely replace its previous fleet ofradio devices with Motorola Solutions’ LTE-based
Wave PTX radio service, becoming the first majorcontainer terminal in Korea to adopt LTE-based
radio communication technology fully.
As SNCT could not fully guarantee the safety ofits employees and partners with its previous radio
fleet, changing its communication infrastructure
became a necessary investment to adequately
prioritise workplace safety for all personnel
working on its premises.
TLK 100

SNCT’s vast terminal is constantly packed withcontainers, cranes, and other steel structures. As
a result, workers are frequently experiencing
communication disruption because of the steel
materials they are surrounded by. Shadow areas
have become an unavoidable operational pain point
at SNCT.
Disruptions in communications create risky
situations for employees and partners at theworkplace. For instance, the crane operators
would become unreachable in the field via theirradios because they were surrounded by piles ofcontainers. Maintenance workers in the machineroom or workers operating quay cranes often
needed to step out to communicate with one
another.
In other instances, for workers in the machinerooms or teams in the control rooms, thesurrounding steel structures were causing
interferences, impacting the effectiveness of teamcollaboration and safety. Controllers would sendout messages to field workers but they were notreceived due to signals blocked by their surrounding
steel materials.

TLK 150
CASE STUDY | WAVE PTX TLK100 & TLK150

By introducing WAVE PTX service and radiomodels TLK100 and TLK150 into SNCT’s operations,personnel who need radio communications
can enjoy a communication environment withzero shadow areas. The new environment hascompletely eliminated the possibility of accidents
resulting from communication interferences.

SNCT recognised the need toeliminate safety failure risks.
Tackling shadow areas is a serious
safety issue for us and a top priority
for the proposed new communicationenvironment.
Many shadow areas elevated oursafety risk levels and impacted
our operational efficiency. Fieldworkers could have communicatedto the controller to stop the crane
via their radios, but the controller
did not receive their messages. And
the crane would continue with its
operations.
We clearly needed to consider othertechnical solutions for the safety of
our employees and partners.

MAPPING A PATH TO
ACHIEVE 100% SEAMLESSCOMMUNICATIONSROBUST COVERAGE, VOICEQUALITY, AND DURABILITY- KEY REASONS BEHIND
SNCT'S DECISION

Initially, the IT team considered switching to adigital system and installing repeaters to eliminate
shadow areas. However, too many shadow areas
required an enormous investment to acquiresufficient repeaters. There was also the challenge
securing adequate radio channels to serve eachteam. Changing the radio frequency channels was
also a laborious process, requiring all radios to bephysically collected back from teams to reset thechannels. For these reasons, SNCT looked to LTE
radios as the alternative solution.

SNCT selected Motorola Solutions’ LTE radios after
being most satisfied with their test results; Motorola
Solutions’ TLK100 and TLK150 scored the highest in
all test scores. SNCT tested the radios throughout
the terminal, from siloed locations to areas whereusers are surrounded by piles of containers or users
are located up to 50 metres high from tall quay
cranes. No shadow areas were discovered, and voice
quality was excellent.

SNCT spent two months evaluating available
options, and tests confirmed that LTE radios could
effectively remove shadow areas. SNCT was also
pleasantly surprised that replacing their previous
radio fleet with LTE radios, even with monthly
communication bills, would cost 20- 30% lessthan installing repeaters on their vast premises.
Changing channels on LTE radios was also easily
done over-the-air from a centralised management
portal.
SNCT finally decided on introducing 90 units ofMotorola Solutions’ portable LTE radio TLK100 and
87 units of the vehicle-mounted LTE radio TLK150.
Almost every workers at the terminal also use theRemote Speaker Microphones(PMMN4125) with
their TLK 100s.

CASE STUDY | WAVE PTX TLK100 & TLK150“We were thinking of installing Wi-Fi accesspoints if shadow areas were found within the LTEenvironment, but everything went so well that wedid not need to do that,” said an SNCT official. TheMotorola Solutions’ radios also offered clear voice
and loud alert sounds, better than any other radios.
That was a significant factor that improved workers'safety.
At the container terminals, the radio’s durability wasalso important. Workers carry their radios at all times,
and it is common to often drop them onto hard, steel
structures from great heights when yard tractors arestrongly jolted while at work. The Motorola Solutions
TLK100 and TLK150 again achieved the highest
scores in these durability tests.
Finally, Motorola Solutions also offered vehiclemounted radios TLK150s, which were not available
from the competition. TLK 150s provided convenience
to users operating yard tractors, those inside cranemachine rooms, and control room operators.

We do not recommend using smartphones at container terminal
work sites. This may result in negligence as a severe accident
in a brief moment could occur of inattention. Worksites areplaces that highlight the role of radio use. After changing tothe Motorola Solutions LTE radios(TLK 100 & TLK 150), we areassured of seamless communications with workers wherever
they are. Now we can look forward to a future of zero risks andaccidents.
Jeong Hoe-jae
SNCT IT Team HeadSAFETY PRIORITISED, FIELD WORKERS’ USERSATISFACTION GAINED
What do the field workers who are the end users of Motorola Solutions’ LTE radios think about
them? They cannot be happier with their new radios. An operator in the container yard said,“Seamless communications mean peace of mind. I can use it the same way as my previous radio,
and it’s more compact, lighter, and easier to carry.”“I used to face endless complaints from field workers at meetings. They often asked me when
I would be able to resolve the shadow area issues. This project was initially scheduled tocommence in 2023, but we decided to bring this forward a year. After we replaced our fleet with
Motorola Solutions’ LTE radios, we have received zero complaints. In addition, the Motorola
Solutions WAVE PTX PTT smartphone app allows administrators to connect with workers
across the field even when they are out of the terminal’s premises.” said Jeong. Being true tothe company’s managerial philosophy of “safety and communications are our organisation’sculture,” SNCT valued workers’ safety more than anything else and introduced the advanced
technology to add value to society and further upgrade its business competitiveness.
