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
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. 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 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. See also three Esperanto radio stations :
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
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 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.
