3G Today
3.1 3G Today
As stated before, CDMA2000 and WCDMA are the two most relevant technologies in use today. They are the dominant forces in 3G. CDMA2000 was one of the first operational 3G technologies, and was capable of transmitting data faster than dial up. Now over 285 million people are using CDMA2000 and enjoying the increased throughput capabilities and data services over 2G technologies.
There is also WCDMA, or Wideband Code Division Multiple Access. This is also known as UMTS, or Universal Mobile Telecommunication System, and is most often chosen by GSM operators. UMTS is completely backwards compatible with GSM and GPRS systems that were widely used in Europe. This makes the evolution from existing 2G technologies to 3G much simpler. WCDMA offers rates faster than dial up services and average rates that are greater than both GSM and GPRS. Over 130 million subscribers are using WCDMA solutions for their mobile and voice needs today.
3G wireless services, including CDMA2000 and UMTS enable consumers and professionals to experience excellent voice quality as well as a wide array of compelling data services today, including:
• Mobile Internet Connectivity
• Mobile Email
• Multimedia services, such as digital photos and movies
• Wireless Application Downloading
• Video-on-Demand
