중대한 전환점에 놓인 무선 인터넷 산업을 진단하기 위하여 휴대 전화기를 기반으로 하는 기존 무선 인터넷 서비스 비즈니스와 더불어 최근 국내에서도 휴대 인터넷이라는 이름으로 업계의 관심을 끌고 있는 모바일 광대역 무선 접속 기술들을 비교하여 소개하고, 각 지역별로 무선 데이터 서비스의 최근 서비스 동향을 살펴봄으로써 앞으로 동 비즈니스가 어떤 흐름으로 전개될 것인가에 대하여 논의해 보기로 하겠다.

국내 무선인터넷 가입자 수가 2003년 5월 기준으로 3,000만 명을 넘어서고 있다. 이같은 수치는 전체 이동전화 가입자의 91%에 이르며, 매출액 측면에서도 전년도 대비 두배 이상 성장하면서 외형적인 성장을 거듭하고 있다...

The roadmap process entails a continual updating exercise. This ITR4 Release November 2002 has combined, revised, added new emerging interests and will supersede the following:

• ITR1 Release July 2000 (“Broadband Access and Mobile Wireless”);
  
• ITR2 Release March 2001 (“Broadband Access and Mobile Wireless Updates”, “The Connected Home”, “Infocomm Security in e-commerce”);
  
• ITR3 Release February 2002 (“Next Generation Optical Networks and Photonics”, “Next Generation Internet Applications”) remains valid and current.
  
  

Objective of Roadmap Reports

• Summary of Worldwide Technologies, Standards and Applications.
  A key objective of this roadmap report is to provide a good overview of past and future developments worldwide, the efforts of key standardisation bodies and industrial forums for interoperability. The report also aims to promote a good understanding of the market and technology undercurrents which are constantly evolving.
  
• Collective Vision for Alignment of Resources.
  The fast changing landscapes, the multidisciplinary nature of emerging technologies, competing and converging technology standards, and heightened user expectations call for a more collaborative and managed approach to technology development. For this, the report aims to derive a common vision and directions for future work, reflective of the joint work effort between the industry, government, research community and academia. Where possible and appropriate, we would include strategic gaps and opportunities for collaborative exploitation. The roadmap exercise aims to identify synergies and complementary expertise so that we can pool our resources, leverage on each other’s strengths to seize technology opportunities.

무선인터넷 콘텐츠사업자(CP)나 솔루션업체 10개 중 7개는 무선인터넷 개방의 장애요소로 이동전화 사업자들의 폐쇄성을 꼽은 것으로 나타났다.

무선망 개방의 장애요소

SK텔레콤, KTF 등 이동통신사들의 부서 이기주의와 실적주의가 모바일 콘텐츠 아이디어를 사장시키는 결과를 낳고 있다.

업계에 따르면 위치기반 서비스, 그림친구, 벨소리, 게임, ARS 등을 서로 결합한 이른바 ‘하이브리드형’ 모바일 콘텐츠에 대한 기획안을 속속 내놓고 있으나, 이동통신업체들의 부서간 협조가 원활치 못해 번번히 묻히고 있다
