An umbrella time period that encompasses the 1/3 era (3G) radio technology developed through the 3GPP (Third Generation Partnership Project), a collaborative challenge designed to supply Technical Specifications and Technical Reports for a 3G Cellular gadget based on evolved GSM Core Networks in addition to the radio Access technology related to them. The most not unusual variation of UMTS employs the W-CDMA air Interface. As a end result, the 2 terms are commonly intercHanged.
The Universal Mobile TeleCommunications System represents a entire gadget. That manner, it consists of Cellular Phones (and other Cell Device), the radio infrastructure needed to provide name and statistics consultation offerings, the core commUnity device for transPorting consumer calls and statistics, the billing sySTEMs, and the security structures, amongst others.
Because UMTS has deep GSM Roots, it's far on occasion referred to as 3GSM. However, because the name W-CDMA implies, it additionally Makes huge use of CDMA era.
Upgraded UMTS Networks around the globe are capable of provide fast down load speeds of up to fourteen Mbps thru the HSDPA (High-Speed Downlink Packet Access) Protocol. Faster Uplink speeds of up to 5.7 Mbps are Currently underway thru the HSUPA (High-Speed Uplink Packet Access) protocol. Both HSDPA and HSUPA are a part of a bigger family of protocols called High Speed Packet Access (HSPA).
Because UMTS is Constructed on GSM networks, it enjoys the identical global Roaming competencies. Practically all UMTS telephones are able to Switching to GSM Mode. That way, if you’re the use of a UMTS device and take place to wander far from a UMTS commuNity and into a GSM network, you may still avail of cell services the usage of the equal cellphone (supplied of path the essential roaming agreements are in vicinity).
Like their GSM predecessors, UMTS phones also include an upgraded SIM (Subscriber IdEntity Module) known as the USIM (Universal SIM). UTMS telephones can work with either SIMs or USIMs.
With the wi-fi industry now shifting from 3G to 4G, UMTS serves as the basis of the 3GPP’s new set of radio technology, referred to as Long Term Evolution (LTE).
Networks upgrading from GSM to the Universal Mobile Telecommunications System are able to reuse some of community factors, such as: the Home Location Register, Visitor Location Register, Mobile Switching Center, and the Authentication Center, to name a few. However, a new Base Station Controller and Base Transceiver Station is needed.
In maximum Instances, 3G and 2G networks could be made to perForm side by means of side.
When we refer to UMTS as an acronym of Universal Mobile Telecommunications System, we mean that UMTS is formed by taking the initial letters of each significant word in Universal Mobile Telecommunications System. This process condenses the original phrase into a shorter, more manageable form while retaining its essential meaning. According to this definition, UMTS stands for Universal Mobile Telecommunications System.
