Chapter 9 Interfaces See the following table for a comparison between 2G, 2.5G, 2.75G, 3G and 4G wireless technologies. Table 108 2G, 2.5G, 2.75G, 3G, 3.5G and 4G Wireless Technologies NAME TYPE MOBILE PHONE AND DATA STANDARDS GSM-BASED CDMA-BASED DATA SPEED 2G Circuit- GSM (Global System for Mobile switched Communications), Personal Handy- phone System (PHS), etc. Interim Standard 95 (IS-95), the first CDMA-based digital cellular standard pioneered by Qualcomm. The brand name for IS-95 is cdmaOne. IS-95 is also known as TIA-EIA-95. Slow 2.5G Packetswitched GPRS (General Packet Radio Services), High-Speed Circuit-Switched Data (HSCSD), etc. CDMA2000 is a hybrid 2.5G / 3G protocol of mobile telecommunications standards that use CDMA, a multiple access scheme for digital radio. 2.75G Packet- Enhanced Data rates for GSM Evolution switched (EDGE), Enhanced GPRS (EGPRS), etc. CDMA2000 1xRTT (1 times Radio Transmission Technology) is the core CDMA2000 wireless air interface standard. It is also known as 1x, 1xRTT, or IS2000 and considered to be a 2.5G or 2.75G technology. 3G Packet- UMTS (Universal Mobile CDMA2000 EV-DO (Evolution-Data Optimized, switched Telecommunications System), a third- originally 1x Evolution-Data Only), also referred to as generation (3G) wireless standard EV-DO, EVDO, or just EV, is an evolution of defined in ITU specification, is sometimes CDMA2000 1xRTT and enables high-speed wireless marketed as 3GSM. The UMTS uses GSM connectivity. It is also denoted as IS-856 or High infrastructures and W-CDMA (Wideband Data Rate (HDR). Code Division Multiple Access) as the air interface. The International Telecommunication Union (ITU) is an international organization within which governments and the private sector coordinate global telecom networks and services. 3.5G Packetswitched HSDPA (High-Speed Downlink Packet Access) is a mobile telephony protocol, used for UMTS-based 3G networks and allows for higher data transfer speeds. 4G/LTE Packetswitched The LTE (Long Term Evolution) standard is based on the GSM and UMTS network technologies.
