Getting to Know 3G Development
Posted by admin | Posted in body language | Posted on 05-08-2009
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/TD-SCDMA, 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.
