ITU-R 권고안을 토대로 미래 IMT-2000 무선망에서의 소요 서비스 채널수 및 지상계 주파수 요구량을 분석한다. IMT-2000 가입자가 요구하는 서비스를 크게 회선과 패킷교환 서비스로 분류하고 옥내, 보행자 및 차량용의 가입자 이용 환경을 고려한다. 본 논문에서는 2010년경 각종 IMT-2000 서비스에 대한 시장성과 무선 전송 기술의 파라미터 값을 이용하여 가입자의 기준 트래픽과 셀내 발생 트래픽을 계산하고 필요한 무선 채널수 및 소요 주파수를 산출한다. 또한, ITU-R에서 권고한 기준 트래픽을 바탕으로 서로 다른 가입자 수와 트래픽 분포 및 이용 환경에서 필요한 무선 채널수와 소요 주파수를 산출하며, 채널수와 주파수 요구량에 대한 패킷 서비스 지연시간의 민감도를 분석한다.
