Before the 4G - changes among leaders

Generation Mobile" - a new era in telecommunications. The data rates offered by the 4G systems will allow
to transmit HD television to mobile devices.



The year 2010 promises to be a breakthrough in wireless communications. Everything seems to indicate that the 4G standard will be adopted and practically implemented by the first commercial networks using this technology. The promise of huge investment gives rise to increasing speculation which of the industry tycoons is best prepared to become a world leader in wireless communications. Last year, the leader was Ericsson (36% market share), the second place took Nokia (20%), and the third - Huawei (11%). However, this year brings some significant change to that ranking. According to forecasts, by the end of the year the annual turnover of Ericsson will come to US$ 26 billion, of Huawei - 18.4 billion, and of Nokia - 15.7 billion. The Chinese giant will probably increase sales by 21%, just opposite to Nokia with about 22% drop in the figure.

Is there a chance that the trend of rapid growth of Huawei's market position will continue in the next year?

Huawei is a world leader of TD - LTE technology which has been selected by China Mobile as the basis for the construction of Chinese 4G network. Installation of the infrastructure will start as early in the beginning of 2010. Huawei will be the primary equipment supplier. Already in May, at the Expo 2010 in Shanghai, a pilot 4G network will start operation in China. The potential of the Chinese market may be crucial, but equally important is the winning of the prestigious tender for 4G in Norway. Huawei beat Ericsson in the Nordic market, which was quite a sensation. Advanced talks between Vodafone and Huawei on 4G in the German market may indicate that it will be another success of the Chinese supplier. Similar negotiations are conducted in Spain. Great potential of Huawei allows for rapid growth, so in 2010 it may become a global leader in wireless technologies.

The 4G system should guarantee mobile data transfer rates of 100 Mbps, and in the case of fixed equipment - 1 Gbps. Development of mobile technology in the direction of 4G is currently achieved mainly in two ways: WiMAX and LTE.
In November this year, ITU (International Telecommunication Union) approved 6 solutions as the basis for the final decision on the adoption of international standard, among them LTE (including Chinese TD-LTE) and WiMAX 2.0 (802.16m). Final adoption of the standard is to be announced on next year's October. Specialists estimate that China may own more than 40% of patents concerning leading telecommunications technologies.

Multiswitches for professional installations


Technical parameters significantly better than those of similar devices on the market, reliability, extensive range of models well-suited for the requirements of investors, 24-month warranty, availability of quick service - are the criteria allowing to include some equipment to the professional group. TERRA multiswitches fulfill these requirements, and, according to opinions of installers and the editorial staff of "SatKurier", are the best products on the market.
TERRA company provides two kinds of these devices: cascadable multiswitches (MS series) and radial multiswitches (MSR and MSV series - the latter can be powered remotely). TERRA multiswitches allow to build SMATV systems up to 1000 outlets. Each of the series is divided into two subgroups: 5-input (for one satellite and terrestrial TV) and 9-input (for two satellites and terrestrial TV).


2009 Nobel Prize in physics for groundbreaking achievements in fiber optics

The Royal Swedish Academy of Sciences awarded half of this year's Nobel Prize in physics to Charles K. Kao "for groundbreaking achievements concerning the transmission of light in fibers for optical communication", and the other half jointly to Willard S. Boyle and George E. Smith for the invention of the CCD sensor.

The research conducted by the Chinese physicist allowed a rapid development of fiber optic technology. First experiments with rays of light guided by glass fibers were conducted in 1870. Thanks to the phenomenon of total internal reflection the beam was propagated through the fiber, but the transmission was possible only on short distances. This resulted from high attenuation of light waves, reaching up to 100 dB per kilometer (currently, attenuation of modern optical fibers is about 0.2 dB/km).

The situation radically changed in 1966 when Charles Kao published the results of his research and pointed out the cause of so high attenuation. He proved that pollution of the fiberglass with hydroxide ions and ions of elements such as iron, copper and cobalt was the main reason of this phenomenon. The study also proved that another reason of increased attenuation was dissipation of energy occurring in the glass structure due to its inhomogeneity. Thanks to the publication of Ch. Kao, already in 1970 the followers were able to obtain the first pure glass fibers without such contaminants and flaws.

Currently fiber optic networks connect the whole world being the main means of communication and transmission of huge volumes of data between any parts of the worldwide information infrastructure. Nowadays fiber optic installations are competitive in price compared to traditional wiring, and they have far more transmission capacity. It's the reason why they start to reach end users (FTTH - Fiber To The Home).
