Current Trunked Radio System in Korea • Currently, there are various trunked radio system being used in Korea: • Analog trunked system • SmartZone, SmartNet • EDACS • Starex • SmarTrunk • LTR • Digital trunked system • TETRA • iDEN • Markets using trunked radio system: • Public Safety • Transportation • Utilities (Electricity, Water) • Oil & Gas • Commercial Communication • Trend is toward migration to digital system
Frequency Allocation • 800 MHz Band (806~824/851-869Mhz) has been allocated for Digital Trunked Radio System for both public and private system • 380 MHz Band (380~390/390~400Mhz) has just recently open to allow private company to deploy trunked radio system • The frequency scheme complies TETRA Standard. • GRN frequency band has not yet allocated • New PPDR band will be allocated according to WRCrecommendations

Deployment of TRS in Korea • History of deployment of trunked radio system in Korea: • First, analog system for Port Tel, POSCO, KEPCO, TBS, Seoul Taxi, Air Force, Doosan Industry, SK, SFD, Korea Racing, Daewoo Ship, • Then, digital system for KT PowerTel, KTX, Incheon Airport, • KNP migrated analog EDACS system to Tetra system. • Regulation / policy for TRS • Digital trunked system is encouraged for spectral efficiency. • MIC drives 800Mhz band for public/private trunked system • and 380Mhz band for private trunked system.
Applications of Trunked Radio System • TRS applications can be divided into two: • Private / Professional Mobile Radio Users • Public Safety organizations • Transportation agency • Utilities Company • Oil & Gas Company • Public / Commercial Users • Small business group for Communication • Construction Enterprises, etc • Both major markets will need a separate network due to different characteristics and requirement from end-users. For example: • Coverage requirement • System performance • Grade of Service • System Security

TETRA system in Korea • TETRA has been widely accepted as digital trunked radiosystem solution in Korea • Korea National Police • Select TETRA system as new communication system . • Has been used TETRA since 2001. Just completed its expansion to form TETRA nationwide network. • Has been proven its performance during FIFA World Cup 2002. • The network is designed to support mission-critical users like KNP • Busan Urban Transit Authority • TETRA System has been selected and the equipment has been arrived at Busan for installation.
Our Principle in Adopting Digital TRS in Korea • Full digital system • Integrated voice and data • Multimedia : image, video • Spectrum Efficiency • Security • Authentication • Encryption over the air • Adaptation of localized encryption via end to end user • Open standard at international level • Air Interface, protocol, ISI • System Stability, Reliability and Survivability • Never dying at any emergency situation
