Getting to Know 3G Development 3G used to be a lot less powerful in terms of coverage and efficiency a few years back. Some of the biggest nations of the world introduced and launched initial models, then continued to develop the details to further cater to the needs of consumers all over the world. There are approximately 3 billion mobile subscribers in the world, with 3G starting to take a big piece of the pie. Here are some more information about the growth. Spreading More Turkey auctioned 4 IMT 2000/UMTS standard 3G licenses with 25, 35, 40 and 45 MHz top frequencies in November 2009. With the 358-million euro offer by Turkcell, it has availed of the 45 MHz band, followed by Avea and Vodafone leasing the 35 and 40 MHz respectively for 2 decades. The only one available for auction at present is the license for the 25 MHz top frequency. A 3G video call created from Johannesburg, South Africa via the Vodacom network in November 2004 was the very first use of 3G technology in Africa. EMTEL in Mauritius launched the first commercial 3G in Africa via the W-CDMA standard. In March 2006, a 3G service was given by the emerging company Wana in North African Morocco. 3G HSDPA services was implemented by Rogers Wireless in Eastern Canada as early as 2007 via Rogers Vision. Fido Solutions and Rogers Wireless currently provides 3G service in several urban centers. Rates of Data The ITU has not yet given a concrete description of the data rate that consumers can get from 3G providers or equipment and tools. The consumers who were given 3G service may not clearly point out a suitable standard, indicating that the rate given are met adequately. In a commentary, it was stated that the expectation for IMT-2000 will give higher rates of transmission, having a minimum speed of 2Mbit/s and the highest at 14.4 Mbit/s for stationary consumers. 348 kbit/s can be expected in a moving vehicle. The ITU does not specifically indicates a minimum or average rates or the modes of the interfaces that can be considered as 3G technology, so different rates are offered and sold as 3G, which are expected to meet the expectations of consumers with broadband speed. Industry sources recommend that 3G can give 384 kbit/s at or lower than pedestrian speeds, with only 128 kbit/s inside a moving vehicle. Although EDGE is included in the 3G standard, a number of phones say that 3G network availability and EDGE have separate functionality. Standardizing the Network The ITU or International Telecommuncation Union described the demands for 3G mobile networks, using the IMT-2000 standard. The 3GPP or 3rd Generation Partnership Project is a group that continues to work by describing a mobile system that meets the standard of IMT-2000. The system is known as UMTS or Universal Mobile Telecommunications System. There are 6 radio interfaces in IMT-2000 namely, W-CDMA or UMTS, CDMA2000, UWC which is implemented frequently with EDGE, TD-CDMA/TDSCDMA, DECT and Mobile WiMAX. On Advantages UMTS is based on layered services, apart from GSM. The top of the line is the services layer, which gives quick deployment of services, plus a centralized place. At the center is the control layer, which supports the upgrade of processes and provides the capability of the network to be allocated in a dynamic manner. At the bottom line is the connectivity layer, wherein any type of transmission technology can be applied, with the voice traffic transfering over IP/RTP and ATM/AAL2.
