Mobile phone is related with our every day life. We can not imagine our life without mobile phone. Now we notice that the development of GSM mobile phone.Robert Conway, head of the GSM Association, said the memorandum of understanding signed in 1987 is widely seen as the moment when the global mobile industry got under way.
Although work on the GSM technical specifications began earlier, the agreement signed in 1987 committed those operators to building networks based upon it.
GSM FACTS
China has 445 million GSM customers
There are 2.5 billion GSM connections worldwide
64% of mobile users are in emerging markets
About seven billion text messages are sent every day

Since then, he said, the numbers of people using GSM mobiles has always outstripped the predictions.
Once the preserve of the well off, mobiles were now "the everyday gadget that's essential to people's lives," he said.
In the UK there are now more mobiles than people according to Ofcom statistics which reveal that, at the end of 2006, for every 100 Britons there are 116.6 mobile connections.
Figures from the GSM Association show it took 12 years for the first billion mobile connections to be made but only 30 months for the figure to reach two billion.
"In the developing world they are becoming absolutely indispensable," said Mr Conway.
This was because handsets were now cheap and mobile networks much less expensive to set up than the fixed alternatives.
There are so many phones that recycling them is a problem
But getting mobiles in to the hands of billions of people was just the start, said Mr Conway.
"The technology is a gravitational force that brings in to its orbit a huge amount of innovators," he said.
In the future, he suggested, high-speed networks would be ubiquitous adding the intelligence of mobiles to anything and everything.
"The technology will be in the fabric of your clothing, your shoes, in appliances, in your car," he said.
For instance, he said, the ubiquity of mobile technology could revolutionise healthcare and see people wearing monitors that gather and transmit information about vital signs.
Phones too could change radically in the future.
"You'll pull them out of your pocket and they'll look like a map but unfold like a screen," said Mr Conway. "We're now on the verge of another wave and that's going to be stimulated by mobile broadband."
Future of mobile
Korea has hugely developed in the mobile technology. It has great significance for development of their economic sector.
In this paper, we discuss the development of wireless and mobile communications in Korea, current technological trends, and the future outlook on technological developments. Since the introduction of the telegraph and the telephone in September 1885, Korea's wired and wireless communications industry has consistently developed for over 100 years. Since 1984, upon the provision of the mobile telecommunications service, the industry has seen drastic qualitative and quantitative growth in terms of both technical and economic aspects, which played a crucial role in the rapid growth of the digital industry in Korea. After the era of the analog cellular service based on the Advanced Mobile Phone System (AMPS), a precursor to the modern mobile service, Korea became the world's first country to commercialize Code Division Multiple Access (CDMA) in 1996 and succeeded in commercializing CDMA 2000 1x (IMT-2000) in 2001. With further developments in the mobile communication technology, the technology for antennas also saw drastic advancements. As the mobile antennas moved from the second to the third generation, they grew from external models to very small internal models. At the same time, they evolved into highly functional and high performance multiple band and wide band antennas. Furthermore, Korea was the first country to commercialize and offer the Wireless Broadband Internet (WiBro) service in 2006. By leading the wireless communications standardization and exerting remarkable efforts in research and development, Korea is consolidating its status as an Information Technology (IT) leader in the global market. The antenna's inherent importance will be further emphasized in the near future as it satisfies the performance and structural needs of portable terminals necessary for realizing the projected establishment of the ubiquitous world. It is thought that antenna technologies will not be limited to simple concepts as previously experienced but will utilize various kinds of materials that build the terminals' structure and framework. Moreover, studies will be performed with an emphasis on multiple band, multiple directivity, and ultra-wide band. Accordingly, antenna technologies to which new concepts are applied, such as SMART antenna and MIMO antenna technologies and meta-materials, will surely be effective alternatives.
