3G is the other name for International Mobile Telecommunications 2000 or IMT 2000. This is also known as 3rd generation mobile networking communication as they are defined by International Telecommunications Union. This includes the GSM EDGE facility, the UMTS and the CDMA2000 which are quite as direct as DECT and WiMax. These services are known as wide area telephone services and they also include video calls which would mean wireless data services that call for simultaneous networking services all happening through mobile phones. The data services could go as high as 14 Mbit/s and 5.8 Mbit/s. This would usually take place on the uplink of HSPA+. The 3G network would enable for a more advanced as well as wide ranging network of operating services that brought about great ranges of work with itself. The 3G networks came to be using spectral efficiency and greater network improvement capacity. The wider range of services made for this network to become more wanted. This overall created a wonderful wireless, mobile network that could allow for higher data rates, different facilities at a go, etc.
With the different forms of uses being provided by the 3G mobile networking, there came several EV-DO Revision series since its release in 2002. The EV-DO Rev. 0 was released in 2004. This again got referred as 2.5G as it served to be one of the transitional steps for the revolutionary EV-DO. EV-DO, in fact got extended twice over, since its release. The Revision A services came in 2006 while the next soon came out in plan B with a series of different products coming from this brand. The 3GPP2 came to be the next generation in technology with UMB as the catch on in the product where many CDMA came to be planned as an evolved version of LTE as well.
The LTE as well as the UMB came to be called as the 4G later too with their advancement in technology. So they act as the next steps to 3G. There have been increased downlink as well as uplink speeds in an ascending order of magnitude. This comes to be quite a premature label with 4G IMT-Advanced standards that included LTE, UMB as well as WiMAX II with goals for including 4G data rates with at least 100 Mbps of use. The OFDMA transmission got included through a packet-switch of delivery that could be based on an IP based multimedia that could stream voice, data and other options.
The International Telecommunication Union or ITU has been the 3rd generation among mobile telephone standards which finally brought about the 3G for all. This went by the standards of IMT-2000 in order to bring about growth and greater increase in bandwidth to support the different forms of applications working through it. The GSM or current standard cell phone services could only provide voice media services. But with the 3G it came to bring 14.4 kbps of download rates giving a circuit switched data.
