CDMA 2000

What is CDMA 2000? 

Before we learn about CDMA 2000 first let us learn about what is full form of CDMA. CDMA 2000 is code division multiple access version of the IMT-2000 standard developed by the International Telecommunication Union. 


CDMA 2000 also known as the IMT-CDMA multi-carrier or the 1xRTT.


Overview :
  • CDMA 2000 is a high data rate upgrade path for current users of 2G and 2.5G CDMA standard. It is a unique radio and network access system that is part of the international telecommunication called 2000. It is called a 3G standard.
  • CDMA 2000 allows the basically same spectrum, bandwidth, RF equipment, and air interface framework to be used at each station.
  • The first CDMA air interface CDMA 2000  with 1 × RTT (Radio transmission technology language) indicates that a single 1.25 MHz radio channel used.
  • CDMA 1x support data rate up to 307 kbps for a single user in packet mode. It can provide a throughput rate of up to 144 kbps depending on the propagation conditions.
  • CDMA 1xEV as an also part of IMT 2000. Its provide CDMA carrier with the option of installing radio channel with data only or data and voice only.
  • CDMA 2000 3xRTT standard is used for three adjacent 1.25 MHz radio channel. It can be used together to provide instantaneous packet data.
  • This article gives information about Feature, advantages, application of CDMA 2000 to gives more information about CDMA 2000.
A feature of CDMA 2000 :  
  • Support high-speed data service.
  • It is a global standard.
  • It has the flexibility for evolution.
  • It has improved spectrum efficiency.
  • Support advance mobile service.
  • Leading performance.
  • Industry-leading performance
  • Device selection
  • Flexible migration path
  • Flexible network architecture
  • New common channel structure and operation
  • Ubiquitous idle time operation
  • Global roaming and multi-mode, multiband devices
  • Flexible spectral allocation and efficient use of spectrum
