UMTS is the 3rd generation wireless technology while HSDPA (High Speed Downlink Packet Access) is the feature of UMTS technology where users can download a stream of 14.4 Mbps with HSDPA.
Absolutely yes. Most VZW devices are capable of working in GPRS/UMTS/HSDPA coverage areas so you can talk, text, surf and email with your Verizon device while in Panama.
The Orange network utilizes GSM and UMTS technology and for 3G services; an HSDPA network that currently covers over 90% of the country. Users of the network can use advanced services all over the world due to roaming agreements with 350 GSM and 130 UMTS international networks.
3G is 3rd generation mobile technology. UMTS is one of the technologies under 3G, just like CDMA2000.
Yes. The iPhone 5 can connect to the Internet using Wi-Fi (802.11b/g/n) or cellular (GSM/EDGE, UMTS/HSPA+,DC-HSDPA, CDMA EV-DO Rev. A and Rev. B, LTE).
UMTS Forum was created in 1996.
full form of HSDPA is High-Speed Downlink Protocol Access
Yes... HSDPA 850/ 1900/2100 HSDPA 900 / 1700 / 2100

It is common for most network provider to deploy HSDPA first before doing HSUPA. HSDPA has much faster speeds compared to HSUPA. HUSPA is still absent in many part of world in use. so as far as usage is concerned, HSDPA is more advance as it is more used and needed.
2G Network: GSM 850 / 900 / 1800 / 1900 3G Network: HSDPA 900 / 2100 HSDPA 850 / 1900
HSDPA and EDGE are signal transmission technologies used to carry data over wireless used mainly by cellular companies. HSDPA will form part of 3G+ signals and EDGE is part of the older 2,5G signals. HSDPA means High-Speed Downlink Packet Access.EDGE (Enhanced Data GSM Environment) is a older and faster version of GSM designed to deliver data at rates up to 384 Kbps. HSDPA can deliver data transmission rates of up to 42 Mbps.
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 two years later. A handful of other European countries joined the UMTS bandwagon in the next two years, with South Africa and a few other African countries soon following suit. The U.S. has employed UMTS networks in several large cities, and the number is steadily growing. UMTS is based on the Global System for Mobile (GSM) standard, which is the gold standard in Europe and more than 120 countries worldwide. In fact, UMTS is sometimes referred to as 3GSM. The two systems are not compatible, however. UMTS is incompatible with GSM. Some phones are dual GSM/UMTS phones, but unless that exciting new mobile phone or handset that you can't wait to get your hands on has that kind of duality built in, you will only be able to utilize one mode, the one that came with the device. As UMTS gains in credibility and functionality, experts believe it will overtake GSM as the industry standard. UMTS is already able to operate at a higher frequency than GSM.from wisegeek dot com
