GSM, GPRS, EGPRS 및 EDGE/Evo

GSM은 방대한 영역에서 급성장 중인 성공적인 기술입니다. 지난 2000년 GPRS가 출시되면서 초기의 데이터 제한 문제가 해결되었습니다. 이 패킷 교환 기술 덕분에 모바일 핸드셋 사용자가 인터넷을 사용할 수 있게 되었습니다. GSM은 최초의 디지털 셀룰라 시스템입니다. 통칭 2.5G 무선 기술이라고 일컬어지는 EGPRS, EDGE, EDGE/Evo는 2G(2세대) 무선 기술에 업그레이드 경로를 제공하여 데이터 전송 속도를 높여줍니다. EDGE/Evo는 GSM 모바일 텔레포니 표준의 최신 확장 버전입니다. 소프트웨어 업그레이드와 새로운 사용자 디바이스 덕분에 데이터 속도가 1Mbps에 이르게 되었습니다. 이와 같은 기술이 전 세계에서 폭 넓게 사용되고 있습니다.

향상된 기술임에도 불구하고 상용 제품에 대한 수요는 여전히 높습니다. 따라서 GSM, GPRS, EGPRS, EDGE 셀룰라 시스템 개발자, 검증 엔지니어, 제조 관리자는 하루 빨리 뛰어난 품질과 경제성을 모두 갖춘 제품을 출시해야 합니다. 테스트 및 측정 솔루션 분야의 글로벌 리더인 키사이트테크놀로지스는 시스템과 구성요소의 품질 보장에 기여하는 다양한 종류의 모델링, 개발, 테스트 툴을 제공합니다. 통찰력 강화, 신뢰할 수 있는 측정 결과, 차세대 무선 장치 개발 촉진
