Abstract

In order for developing countries to design and deploy Long Term Evolution (LTE) network in a cost-efficient manner, the differentiated way of technological design and deployment methods are necessary as compared to those for advanced countries. This paper focused on Radio Access Network (RAN) design methodology for developing countries that consists of major part of the network cost. To verify the effectiveness of the suggested design methodology, a Korean telecom company A's actual design experience in an African developing country was examined.

개도국에서 비용 효율적인 LTE (Long Term Evolution)망을 구축하기 위해서는 선진국 위주의 설계 및 구축방식과는 차별화된 LTE 기술 분석과 적용이 필요하다. 본 연구에서는 이동 통신 네트워크 구성에서 대부분의 CAPEX (Capital Expenditure) 및 OPEX (Operating Expenditure)를 차지하는 RAN (Radio Access Network) 구성에 대해 개도국에 적합할 수 있는 설계 방안을 제안하고 사례를 통해 결과 검증을 하였다. 본 연구결과는 향후 개도국들이 도심지역 또는 외곽지역에 LTE 망을 위한 RAN을 비용 효율적 관점에서 설계 및 구축할 때 참고가 될 것으로 판단된다.
