What is UMTS?
UMTS is one of the Third Generation (3G) mobile systems being developed within the ITU’s IMT-2000 framework. It is a realisation of a new generation of broadband multi-media mobile telecommunications technology. The coverage area of service provision is to be world wide in the form of FLMTS (Future Land Mobile Telecommunications Services and now called IMT2000). The coverage will be provided by a combination of cell sizes ranging from ‘in building’ Pico Cells to Global Cells provided by satellite, giving service to the remote regions of the world. The UMTS is not a replacement of 2nd generation technologies (e.g. GSM, DCS1800, CDMA, DECT etc.), which will continue to evolve to their full potential.
UMTS stands for Universal Mobile Telecommunications System. UMTS is one of the emerging mobile phone technologies known as third-generation, or 3G. Third-generation systems are designed to include such traditional phone tasks as calls, voice mail, and paging, but also new technology tasks such as Internet access, video, and SMS, or text messaging. One of the main benefits of UMTS is its speed. Current rates of transfer for broadband information are 2 Mbits a second. This speed makes possible the kind of streaming video that can support movie downloads and video conferencing. In a sense, UMTS makes it possible for you to enjoy all of the functionality of your home computer while you are roaming. By combining wireless and satellite cellular technologies, UMTS takes advantage of all existing options to result in the Holy Grail of 3G presentation: seamless transitions between WiFi and satellite. UMTS went live as a network for the first time in Japan in 2001. Austria had its own network tw
UMTS is an abbreviation for Universal Mobile Telecommunications System. It is one of the third-generation (3g) cell phone technologies quickly developing today. UTMS is also referred to as the 3GSM so as to emphasize the coalition between 3G technology and GSM standard. In theory, the UTMS, using W-CDMA, is supposed to be able to transfer up to 14.0 Mbit/s data transfer rates although real uses have shown a transfer rate of 384 Kbit/s to 3.6 Mbit/s with various handsets. However, this speed is still a lot greater than other competing technologies, which enables a connection to the World Wide Web. Also, UMTS offers videoconferencing, downloading music and video files, along with being able to watch TV shows. However, statistics in countries such as Japan and Korea have shown that the transition is still in process and thus, there are not yet many users using the technology.
UMTS-The Universal Mobile Telecommunications System is third-generation (3G), broadband, packet-based transmission of text, digitized voice, video and multimedia at data rates up to and possibly higher than 2 megabits per second (Mbps), offering a consistent set of services to mobile computer and phone users no matter where they are located in the world. Based on the Global System for Mobile (GSM) communication standard, UMTS, endorsed by major standards bodies and manufacturers, is the planned standard for mobile users around the world by 2002. Once UMTS is fully implemented, computer and phone users can be constantly attached to the Internet as they travel and, as they roam, have the same set of capabilities no matter where they travel to. Users will have access through a combination of terrestrial wireless and satellite transmissions. Until UMTS is fully implemented, users can have multi-mode devices that switch to the currently available technology (such as GSM 900 and 1800) where
