A wireless communication system for a railroad vehicle of the present invention includes: vehicle wireless equipment (VWE) mounted in a railroad vehicle and operating in a wireless LAN access point (AP) mode to perform wireless communication with the outside; and a plurality of ground wireless equipment (GWE) installed on a road through which the railroad vehicle passes and operating in a wireless LAN AP mode to perform wireless communication with the VWE. The VWE performs wireless communication with the GWE through a simultaneous access mode of concurrently connecting the GWE in 1 : N (positive number equal to greater than 2) based on the location information and the reception level information of the GWE, and a dual frequency mode for forming multiple communication paths with the GWE and using different frequencies. It is possible to provide high-speed and stable communication quality.

    본 발명의 철도 차량용 무선통신 시스템은, 철도차량 내에 탑재되며, 무선랜 AP(Access Point) 모드로 동작하여 외부와 무선통신을 수행하는 차상무선장치(VWE); 및 상기 철도차량이 통과하는 도로변에 각각 설치되며, 무선랜 AP(Access Point) 모드로 동작하여 상기 차상무선장치(VWE)와 무선통신을 수행하는 복수의 지상무선장치(GWE)들을 포함하며, 상기 차상무선장치(VWE)는, 상기 지상무선장치(GWE)들의 위치정보 및 수신레벨 정보를 기반으로 상기 지상무선장치(GWE)들과 1 : N(2이상 양수)으로 동시 접속하는 동시 접속방식 및 상기 지상무선장치(GWE)들과 멀티 통신경로를 형성하고 서로 다른 주파수를 사용하는 이중화 주파수 방식을 통해 상기 지상무선장치(GWE)들과 무선통신을 수행하는 기술을 제공함에 기술적 특징이 있다.
