3Gpp

[1]3Gpp(3rdGenerationPartnershipProject,第三代合作伙伴計劃)的目標是實現由2G網絡到3G網絡的平滑過渡,保證未來技術的后向兼容性,支持輕松建網及系統間的漫游和兼容性。其職能:3Gpp主要是制訂以GSM核心網為基礎,UTRA(FDD為W-CDMA技術,TDD為TD-SCDMA技術)為無線接口的第三代技術的規范。

  • 2015_01_3Gpp_unlicensed_Dino_Flore

    Licensed spectrum remains 3Gpp operators’ top priority to deliver advanced services and user experience Opportunistic use of unlicensed spectrum is becoming an important complement for operators to meet the growing traffic demand Moving forward 3Gpp operators will have two options to offload traffic to unlicensed spectrum: 1. Wi-Fi (via LTE/Wi-Fi interworking) 2. LTE over unlicensed It will then be up to each individual operator to choose which approach to use, which will depend on a number of factors

  • Essentials+of+LTE+and+LTE-A

    The next-generation wireless broadband technology is changing the way we work, live, learn, and communicate through effective use of state- of-the-art mobile broadband technology. The packet-data-based revolu- tion started around 2000 with the introduction of 1x Evolved Data Only (1xEV-DO) and 1x Evolved Data Voice (1xEV-DV) in 3Gpp2 and High Speed Downlink Packet Access (HSDPA) in 3Gpp. The wireless broad- band fourth-generation technology (4G) is an evolution of the packet- based 3G system and provides a comprehensive evolution of the Universal Mobile Telecommunications System specifications so as to remain competitive with other broadband systems such as 802.16e (WiMAX)
