What is Universal Terrestrial Radio Access (UTRA)?

What does UTRA stand for?

Universal Terrestrial Radio Access (UTRA) is a fashionable for 3G Cell communications services devised via the third Generation Partnershop Project (3GPP). UTRA get entry to is based totally on direct-unfold Wideband Code, which includes department more than one access and hybrid time-division get entry to techniques designed for 3G frequency perFormance, mobility and Exceptional of Carrier necessities.

UTRA identifies the radio Modes of get entry to for regular cell Telecommunications gadget Networks. UTRA’s get entry to commUnity is known as typical terrestrial radio get right of entry to network (UTRAN).

What Does Universal Terrestrial Radio Access Mean?

UTRA is one of the most usually used 3G mobile communications technology. This time period includes the Device architecture (3GPP TS 25.301) and its bodily Layer (3GPP TS 25.201), along with all of the different Components of the radio era defiNition (25.-series).

UTRA will stay aggressive for several years for each Downlink and Uplink with the Upgrades furnished by high-speed Packet get entry to. The enterprise that has advanced 3GPP technologies has launched a long-time period evolution (LTE) project within 3GPP, which is focused on improving the UTRA wellknown and optimization of the UTRA architecture.
