From the perspective of standing to enhance the competitive advantage of an enterprise to build a multi-language site is the increasing number of customers premise and efficient means to increase sales.
With the accelerating of the process of internationalization, multilingual website will become an indispensable part of businesses and organizations.

Multi-language website to help businesses face many non-English speaking Internet users
Change over time, the proportion of
non-English speaking Internet users is constantly rising. Compared to the previous situation by English-speaking users to control the Internet has produced a fundamental change. 
Foreign Internet market is the mature fruit, as long as you are willing to pay less effort will be able to get a huge harvest. The results show that the Internet tends to slow the growth in the
United States, Britain and Sweden, in other countries such as Brazil, China, FranceItaly, Japan and South Korea grew significantly.
The most readily available opportunities in the country's Internet usage and the user (or site) before the relationship has been established culture in the current growth stage, customers will become the loyal customer base. Multi-language Website an effective marketing tool in the enterprise has the ability of the majority of Internet users to communicate in their own language, which not only means an increase in sales even more valuable is to establish your brand, services and products in the local market known.
The construction of multi-language website is a great program because it is likely that corporate marketing, seize new users, the most effective way to establish new customer relationships and the empowerment of an international image of the corporate brand.

Multi-language Website can bring new customers
By your multilingual website exposure in front of potential customers in various countries, regions, naturally you will get the attention of these native language users.

Multi-language Website to increase sales to the enterprise
On the site to add a language has the potential doubling sales. Even if only to completion of the site contains only
Chinese, Esperanto, French, German, Italian and Spanish website of the five major world languages and one international auxiliary language, its sales may also be potentially up to five or to ten times. This is a rare use of such a small investment for such a large effect.

Multi-language website is able to convey the sense of customer-centric service

TETRA : Placing the last piece of the puzzle for a complete European cross-border communications solution

TWC 2005, Frankfurt: The goal of the Schengen Telecom group of a harmonised solution for Public Safety communications in Europe is close to being fully achieved.

Their vision is for a freedom of communication for all Public Safety Services (PSS) - police in cross border pursuit or other emergency organisations such as Fire and Rescue, Ambulance and Medical services attending a natural disaster.

Hans Borgonjen, TETRA Association Board member and one of the founder members of the combined group of European Public Safety communications officers who have been helping to turn the Schengen vision into a reality, commented that, "Germany is very close to a momentous Public Safety communications decision. Their choice of a new communications technology will be a significant step to completing the harmonisation we are all hoping for."

TETRA has been deployed for PSS use in almost all European countries in the 380-400 MHz frequency band. Germany, the largest and most highly populated country in Europe is one of the last to make its PSS communications decision for a national network. It has already stated in the invitation to tender documentation that the network's technology should be based on the TETRA standard or a comparable technology.

Germany's central role for PSS communications in Europe

Germany's geographical position at the centre of Europe, along with its size and number of inhabitants, self-evidently makes it highly important as far as cross-border PSS communications is concerned. The milestones set this year for building a national public safety network are strongly welcomed.

Mr Borgonjen demonstrated the strong support of the political parties of the CDU and SPD coalition to this new national communications network with reference to a quote directly from the coalition agreement showing the commitment to push forward the plans for building Germany's new public safety network.

"In order to improve PSS communications capabilities we will push the introduction of a digital network ("Einführung des Digitalfunks") in coordination with the federal states and within the framework of the selected operator model. It must be our goal to provide nationwide coverage, a universal standard and a fair cost-splitting between Federal Government and the federal states".

The goals of the original Schengen Telecom group have not changed. Their vision of integrated, multi-user shared networks that cross borders and give emergency service users the lifeline they need when dealing with major incidents has been implemented in many countries in Europe.

Hans concluded that the picture puzzle has most of its pieces already set out across Europe forming a strong and coherent map of TETRA users. He added, "Just one or two gaps remain. The pieces have been identified and the best way to achieve the solution is clear - TETRA. It just remains to put them into place."

TETRA : EADS - CAAC airports to showcase China

EADS has signed a framework cooperation agreement to establish a nationwide TETRA network for China‘s airports.

The network, to be built for the Air Traffic Management Bureau (ATMB), Civil Aviation Administration of China (CAAC), will be the largest digital trunked radio network in China.

During the first phase of the project, a TETRA exchange centre will be set up in the international airports of Beijing Capital, Shanghai Pudong, Shanghai Hongqiao and Guangzhou Baiyun. The base stations in these four airports and the remote base station that has already been set up for the Chengdu airport will be connected to the switching centres, and will form the core of a large nationwide network in a unique hub system.

Together, the five airports serve over 100 million passengers annually. According to market estimates, the number of Chinese air passengers will increase by 100% over the next ten years.

ESPERANTO : Esperanto is ....

Esperanto is a language introduced in 1887 by Dr. L.L. Zamenhof after years of development. He proposed Esperanto as a second language that would allow people who speak different native languages to communicate, yet at the same time retain their own languages and cultural identities. Esperanto doesn't replace anyone's language but simply serves as a common second language. Esperanto can be learned in much less time than any other language. (Some say that it is four to ten times easier). Esperanto is politically unbiased.

Although there aren't a lot of people who speak Esperanto in any one place, there are some almost everywhere. There are over a hundred periodicals regularly published in Esperanto. There are thousands of books in Esperanto, both translated and original works. There are millions of webpages.

People who speak Esperanto are internationally minded, concerned about social justice and peace, and are helping to preserve linguistic diversity. Meetings and conventions in America, Europe, Africa, Australia and Asia provide a fun opportunity to travel and meet new people from around the world.

Esperanto doesn't replace anyone's language but simply serves as a common second language. 
Esperanto is politically unbiased, helping to
preserve minority languages and cultures.
Esperanto provides an
opportunity to travel and meet new friends from around the world. 
Esperanto is fun to learn and fun to speak

ESPERANTO : Is Esperanto four times easier to learn?

If you're an average American or English who does not speak any foreign language fluently, you can learn Esperanto much more easily than you could learn any other foreign language. Of course, if you already speak, say, Italian or French, learning Spanish would be pretty easy. But for most of us, learning any foreign language ― except Esperanto ― would be a long and painful job.

Here's why you'll likely find Esperanto at least four times easier: 

Esperanto is phonetic

In Esperanto, every letter has just one sound; every sound has just one letter representing it. The emphasis is always on the next-to-last syllable. So once you learn the alphabet, you can pronounce anything you read, and you can spell anything you hear. And you can learn the whole system in a few minutes. Compare that with the hour or so a week you spent for half a dozen years in grade school, learning to spell English (without a guarantee that you will get every new word you meet right). And that was your own language!

Esperanto has a simplified grammar

Compared to most languages, Esperanto's grammar is extremely simplified ― stripped down to the bare necessities. For example, verbs have only six endings, and these do not change regardless of person or number ― that is, the ending doesn't change depending on whether "I", "you", "they", or "we" do the action. And the endings never change. Every verb uses only those six endings! Compare this to French, for instance.

Esperanto simplifies building your vocabulary

Esperanto gives you prefixes and suffixes that you can use to multiply your vocabulary and cut down on the number of words you have to learn.

For example, the prefix mal- means "opposite of." So if you know the word for "good" (bona), you know how to make the word "bad" (malbona). Tall (alta) and short (malalta), big (granda) and small (malgranda), possible (ebla) and impossible (malebla), happy (feliĉa) and unhappy (malfeliĉa).

Another example: the suffix -eg- means "very big, very much so." So a big house might be a granda domo, but a mansion would be domego. And now from "rain" (pluvo) you can make "downpour" (pluvego), from "good" (bona) you can make "excellent" (bonega), from "happy" (feliĉa) you can make "overjoyed" (feliĉega). And Esperanto doesn't shortchange smallness, either; in that direction the suffix -et- plays the same role as -eg- for bigness, but we will let you come up with some "small" words of your own as examples

Esperanto lets you invent your own vocabulary

You can combine words, prefixes, and suffixes as you speak to make new words. In English, you can't just stick "un-" in front of the word "recommend" (unrecommend? disrecommend?). In Esperanto, if the opposite of a word ― a noun, a verb, an adjective ― makes sense, go ahead! Malrekomendi is perfectly good Esperanto. You want to really, really malrecommend something? Malrekomendegi! Every Esperanto speaker will get your point.

Esperanto has a recognizable vocabulary

You may have recognized several of the Esperanto words above, or seen related words in English (bona -> bonus, alta -> altitude, feliĉa -> felicitous). About 78% of Esperanto vocabulary is directly or indirectly derived from Latin roots, many of which also appear in English. Another major chunk is from Germanic roots (hundo, hound or dog). So you'll understand a good part of the words with little trouble.

Anecdotal evidence

First, a friend's story. She studied Spanish, then Esperanto. She claimed she learned as much Esperanto in six weeks as Spanish in six months.

Now my own story. I studied Latin for four years in high school; I was pretty good but never reached the point where I could actually speak it. With Esperanto, I've been able to learn it so well that I don't even have to translate when I speak or listen. When I speak it, the words just come out (and usually correctly!); when I listen to or read Esperanto, it's obvious what the words and the grammar mean without having to analyze each word. I was surprised when I realized I had reached that level of fluency, but that's what you can do.

So. Four times easier? Many people think so. Many people even say it's more than four times easier! Try it and see for yourself.



UMTS/3G : HSPA and LTE to be ready for 700 MHz Spectrum Band

Spectrum is the lifeblood of wireless communications worldwide.
The resource that makes connectivity possible.
Careful planning and global coordination of this most valuable asset, such as the work done by the ITU for the 700 MHz spectrum band, will ensure the future delivery of advanced wireless communications services throughout the world. 
This work is particularly relevant for the Americas.

The GSM technology family is rapidly growing in the Americas, taking 62% share of market as of the end of September 2007, and is the only technology present in all 46 countries of the region. 
The third generation of GSM, which includes UMTS/HSPA, is currently commercially deployed on 13 networks in 8 countries of the Americas. 
Many more launches of UMTS/HSPA are anticipated throughout the Americas in 2008. 

The 700 MHz spectrum band has great propagation characteristics and therefore significant value for the wireless industry. 
The decision by the ITU identifies 689-862 MHz for IMT in Region 2, which includes all of the Americas, and in nine countries of Region 3 (Bangladesh, China, Korea, India, Japan, New Zealand, Papua New Guinea, Philippines and Singapore). In Region 1 (which includes Europe, Africa, the Middle East west of the Persian Gulf and including Iraq, the former Soviet Union and Mongolia), the lower 700 MHz band was excluded from IMT operations, starting instead at 790-862 MHz.

“We applaud the ITU for their work in coordinating spectrum and designating 700 MHz as a core band for mobile services,” stated Vicki Livingston, Director of Marketing for 3G Americas. 

Harmonization will facilitate international roaming while minimizing equipment costs and promoting economies of scale, so that successful deployments of HSPA/LTE will ensure delivery of advanced wireless services around the world. 




TETRA : Record-breaking TETRA on the trains TGV

574.8 km/h… that was ETELM’s achievement in France with a TETRA trackside-to-train speech and data transmission during the world speed record for a train. Base stations were located trackside, directly adjacent to the passing train. 
The event was a triumph of co-operation between SNCF (the French Railways), RFF (French Rails) and train manufacturer ALSTOM, with the expertise and support of IGTL (the Railway’s radio communication division) managed by M. Massy who was on the train during the tests and the world record.
Transmissions were made with standard TETRA terminals from EADS...

Pierre Minot, CEO of ETELM said : ‘Not only a technical first, this record inspired a passion and sense of adventure in all involved and sets a new standard at the leading  edge of TETRA development.’

TETRA : Strategic alliance for China market
Hisense, one of the largest electronic technology companies in China, and Sepura, the world's second largest supplier of TETRA radio terminals, have announced an agreement to enable the local manufacture, development and supply of TETRA radios in China.
The radio products will be provided in all frequency bands allocated to TETRA in China. Sepura was the  first company to provide TETRA products for the Public Security 350-372 MHz radio frequency band in China and Hisense will produce these products from its Chinese manufacturing facility, plus other TETRA radios in the 440-473 MHz and 806-870 MHz radio frequency bands.
This arose from the decision by the Ministry of Information Industry (MII) in 2000 to adopt the international TETRA standard for digital radio in China, particularly for use by police, fire, ambulance, transport, ports and metros. MII estimated a potential market in China for 8-9 million digital trunked radio terminals."

TETRA : Beijing Metro replaces 30 year old system
The China Beijing Metro is replacing its existing communication system for its Line 1 and 2 Operations with a TETRA system from Motorola. The new system is expected to be fully operational by the second half of 2007. These were the first metro lines to be constructed in China in the 1960s. 
The migration to a digital platform is part of the five-year plan to upgrade the subway systems and equipment to integrate all metro lines on a unified communications platform. 
"Minimising risks, improving passenger services and raising the safety level and overall standard of our subway operations are some of the key priorities when we were considering a system refresh," said a spokesperson from the Beijing Metro. 



TETRA : Second phase Russian railway project
The Russian railway is the first in the world to adopt TETRA after testing both TETRA and GSM-R technology. The Moscow – St. Petersburg line, which is 800 kilometres long, will bring the system into operation. Teltronic won the initial contract in May 2005, and works with Russian companies Globalsvyaz and Microtest. Specific interfaces have been developed, as well as a complex monitoring system under SORM specifications. The system is also integrated within the existing radiocommunication networks in the Russian railway.
The first project phase included the two central nodes and 19 base stations for 300km of track. The second phase includes another 500 kilometres, making a total of 800 kilometres. A total of 32 base stations are going to be placed in this second phase.



A meshed municipal HIPERLAN 2 vs WiMAX
A blanket municipal coverage is not the only opportunity for mesh WLAN networks as HIPERLAN 2 technology which uses 5 GHz bands.
This technology has also a promising future both in enterprise,  campus environments, medical and in suitable industrial applications.



ZigBee in public safety
The ZigBee network layer is responsible for device discovery and network configuration. It supports star, mesh and cluster tree network topologies.
Mesh capability is a fundamental and differentiating attribute of ZigBee's design.
It means that high power is not required for large networks, as messages can be delivered by hopping from node to node.

The rapid deployment characteristics of mesh networks open up many potential uses in public safety.
Designed to be highly adaptive and scalable, ZigBee allows a new device or network node to be added, adjusting to the addition through a simple request to the master device.

Some possible applications of ZigBee technology for public safety and rescue organizations are :
- Ambulance and healthcare
- Fire brigade
- Police


A meshed municipal Wi-Fi vs WiMAX
The concern for supporters of meshed municipal Wi-Fi is WiMAX, the emerging long range wireless communications standard.
Likely to target fixed network service provision to homes, indoor, confined space and businesses initially, it could also become a killer application for users of mobile consumer technology, as UMTS / 3G, in urban areas, thanks to the inclusion of a mobile version of the standard IEEE 802.16e (WiMAX mobile).

One of the biggest advantages of WiMAX is its broader coverage. It has a range of kilometers, rather than meters, which would theoritically make deployment much easier and cheaper within an urban environnment, especially as WiMAX base stations could potentially be fitted to existing cell towers, lowering the cost of implementation.
Although discrete Wi-Fi hotspots are deployed in their thousands around the world, the implementation of meshed Wi-Fi technology is only slightly ahead of WiMAX, making the race a much closer one.



ZigBee : a new wireless standard
ZigBee is a new wireless standard supports a mesh networking architecture.
A group called the ZigBee Alliance created ZigBee to function on top of the Physical (PHY) and Medium Access Control (MAC) layers, adding application profile and network layers, plus AES-128 encryption security, which can be taillored to meet the needs of an application...

The name is based on the ZigBee principle : the Zigzag path of Bees that serves to signal a new food source to other members of the colony.



The telegram is dead - STOP
"Effective January 27, 2006, Western Union will discontinue all Telegram and Commercial Messaging services. We regret any inconvenience this may cause you, and we thank you for your loyal patronage (saying on its website)."
It is the end of an era. The compagny that was formed in 1855 to exploit the white-hot technology of the telegraph was the last firm in the US to offer telegram services. It may be that telegrams are still offered in a handful of countries around the world but the telegrams of Western Union are no more. From now on the compagny will concentrate solely on offering financial services, such as money transfers.

Nota :

Prior to the telegraph, for instance, the quickest way of sendind a message from New York to California was by the famed Pony Express (diligence), whose delivery service took 10 days. By using the telegraph a message could sent, received, transcribed and delivered in a matter of minutes.

The first commercial machine was made available in Britain in 1837 by Sir Charles Wheatstone and Sir William Fothergill-Cooke. At the same time, a similar device was patented in the US by Samuel Morse, who, with a $30.000 grant from Congress, developed the now famous Morse code signalling system using "dots and dashes" with his assistant Alfred Vail. After weeks of practice and rehearsal, the two men finally display their system in public on 24 May, 1844.
