The first radio technology that was introduced in 1940 was meant for connecting mobile users to the public network. After that, the Bell labs launched their new system called the IMTS or Improved Mobile Telephone Services and improved the dialing and higher bandwidth. After that cellular systems were developed in the places that divided the area into smaller cells and servers to power the transmitter and receiver.
Then came the generation era, the first generation that was made for mobile communication and the invention of the microprocessor helped to connect the cell site.
The second generation was developed at the end of the 1980s and was able to provide the voice signal facility and these new systems provided better and higher quality and at a lower cost.
The third generation provides faster communication services that include fax and the internet as well the voice at the same time anytime and anywhere. The 3g opened the world to the world wide web and progressed the development in the innovative application services.
IMT 2000 ( International Mobile Telecommunication – 2000 )
If we talk about IMT 2000 then there was a time when we have recharge for both data packets and voice calling separately but when the 3G services came into play and IMT 2000 was introduced then only the recharge for both data and the voice was coming in the same recharge.
The IMT 2000 is also known as the 3rd generation and the family of standards belonged to the International Mobile Communication as they were defined by the international telecommunication union which also included the technology such as EDGE and UMTS as well as CDMA 2000 along with WiMAX as well as DECT Technology
THE 3g provides simultaneous access to both voice telephone along with the video calls and also wireless data and all these services with the same mobile environment.
You are also able to provide the data services along with the speech services with very higher data speed (and it can be up to 14 Mbit/s for the download and 5.8 Mbit/s for the uplink facility)
IMT 2000 also became a standard for all the 3G services that came into use. Earlier the name was Future Public Land Mobile Telecommunication System FPLMTS.
The core of IMT 2000 was in a form of wireless interface standard and that included the Radiofrequency bandwidth and also became one of the most commercial applications. Also, IMT -2000 was able to make changes in the data link layer and also for the greater use of the data services and it included the medium as well as the link access control. It also offered the best delivery for the data and the circuit-switched channel for the voice.
The successor for the IMT 2000 and CDMA 2000 was the UMB or the Ulta Mobile Broadband but Qualcomm announces that it will be favoring the LTE instead of the UMB for the development of their technology and hence the LTE became the next commercialized used for the 4G.
IMT 2000 VISION
Increase the data rate up to 2 Mbps
Enhance security and performance.
The IMT 2000 can provide a common worldwide spectrum
To provide multiple radio environment
It also provided worldwide roaming capability and you were able to call from anywhere
Also, better security was provided by the IMT 2000
There was a small terminal that includes worldwide use for the call services
The Satellite, as well as the terrestrial system, were integrated to provide calls from one part of the earth to another and thus the roaming came into play
IMT 2000 Family
IMT-DS is a direct spread technology and also a compromise of a wideband CDMA system that is also used by the European provider. Also, the specifications are provided by the UTRA FDD system.
IMT-TC is a time code that is provided by the ULTRA system and this also provides time-division CDMA.
IMT-SC which was a single carrier technology that was provided by the and that was originally promoted by the Universal Wireless Communications consortium. Now the same is integrated into the 3GPP.
IMT-FT it is a frequency-time technology and is an enhanced version for the cordless telephone standard or DECT
IMT-MC – CDMA 2000 which is a multi-carrier technology and that was standardized by the 3GPP2, and this is also represented as the second mainstream for the 3G technology.
