3G ( 3rd generation nomadic applied science ) uses wideband Code Division Multiple Access ( WCDMA ) to provide wireless internet to fluid exploiter . The most basic 3G protocol represent known as UMTS ( general Mobile River Telecommunications Service ) . We call UMTS the most canonical 3G protocol , because a number of enhanced protocols that offer faster speeds have equal developed from it . They admit : HSDPA , HSPA , and HSPA+ . These enhancement personify backwards-compatible , so any equipment with an advanced or enhanced 3G communications protocol includes support for the low communications protocol . ## What is 3G UMTS, and how fast is it? UMTS (Universal Mobile Telecommunications Service) is synonymous with 3G. This is the protocol that the early 3G sound supported , and information technology delivers data hotfoot of up to 2 Mbps for downloads . ## What is 3G HSDPA, and how fast is it? HSDPA (High Speed Download Packet Access) is an enhanced 3G network protocol that supports data speeds of up to 14.4 Mbps for downloads. information technology is besides know as 3.5G . ## What is HSUPA, and how fast is it? HSUPA (High Speed Upload Packet Access) is a version of HSDPA but with only the uplink enhanced, so it delivers faster upload speeds. It increases upload data hurrying up to 5.76 Mbps . ## What is 3G HSPA, and how fast is it? HSPA (High Speed Packet Access) is a 3G mobile network protocol that offers data speeds up to 21 Mbps for downloads. HSPA be also known A 3.75G . ## What is 3G HSPA+, and how fast is it? HSPA+ (High Speed Packet Access Plus, also called Evolved HSPA) is a further evolution of HSPA. It represent the fast 3G protocol , supporting data rates of 42 , 84 and sometimes 168 Mbps for downloads and up to 22 Mbps for upload . HSPA+ is also commonly call 3.9G , and close to wireless carriers and networks take in marketed information technology , falsely , as 4G . 4G ( 4th generation of mobile technology ) be a whole different mobile wireless standard from 3G . information technology uses the LTE ( long-term development ) protocol . information technology delivers much faster speeds than 3G networks , as fast as 100 Mbps for downloads . bear on : Can you convert angstrom unit 3G telephone to 4G ?
