Network Of The Future With VDSL ?

The abbreviation VDSL stands for very high speed digital subscriber line and in fact is what the rapid development of networks is mainly speed. Data rates of 25 Mbit / s, and later even 50 Mbit / s, are announced for VDSL. In practice this reduces the German Telekom, the length of copper wire to the end customer, as physically simple rule: the longer the copper cable, the lower the amount of data that can be transported. This occurs mainly by the distance from the central distribution station to the local distribution (the ugly gray boxes on the roadside) is now bridged by new fiber optic cable and the signal transducer (so-called DSLAMs), which interpret between copper wire and fiber optic cable, now from the central distribution station in The local distribution wander. If the distance from the local distribution to the consumer not the 300m mark to the announced speeds are respected. So far so good. Despite the tremendous effort, and the no less impressive investment more than three billion euros will not silence the crowd of doubters on VDSL project simple. Why? VDSL is a hybrid technology that combines fiber optic and copper with great effort.

The disadvantages of the copper cable, such as crosstalk, influence them in the parallel data streams of several participants are negative, still remain. The amounts are capped at the top and it can still not all the participants (only about 40-60% are connected). There is also a technique (DSM-dynamic spectrum management), improved by the modulation method and a different encoding up to 100Mbit / s could be realized without new cable infrastructure. Only a rogue would get there no doubt. In addition, say experts estimate that the complete development of a pure fiber network is not up to the end customers would be more expensive than the current plans.

This pure fiber-optic network that would be the future, thanks to the potential for short passive optical fiber technology (GPON gigabit-passive optical network) active even without the previously required amplifier and therefore could do to maintain all the alternatives proposed. VDSL is not only technically interesting but also economically. The German Telekom plans to use its new fast network like on their own and competitors locked out. What a blessing functioning market structures and sufficient competition for us to have customers demonstrates the unique price after the market liberalization, the end of the nineties. All the more incomprehensible is the buckling of the Federal Government of Deutsche Telekom, the monopoly in the future VDSL network. The amendment to the Telecommunications Act by a vote of the grand coalition, known as “lex Telekom”, which is preventing access of competitors for years, will come at us so dear.

Concede NOKIA

And for good reason. What we got looks very solid and even, as applied to Chinese products, stunning! Look of the phone pleasantly surprised by its design and quality components. Perhaps, it is incorrect to compare, given the mentality of our citizens, but where to go, since it deserves – not the quality of parts Concede NOKIA! What is that is – to our surprise there was no limit. Learned, after all, our Chinese friends to do things. Themselves feel like in this paragraph smacks of advertising, but we write it because in the future 100% sure that it is not ashamed to look into the eyes of the owners Anycool T718. First of all, loved covering the back and sides of the phone – soft touch (soft touch – just recalled Globway G208b – GSP automobile navigator – hit of the season 2007/2008 with the same coverage) All those who not touched the phone, noted nice to touch sensations.

'It's like rubber' – the reaction of those who tried. Design, apparently, Koreans were not going to surprise – nothing remarkable, as they say – a classic of the genre. Most of the front side is a great 'touch screen' (touch) screen, below – the main power button functionality, and lower part – the actual numeric keypad with semi-circular convex buttons (by the way, is very convenient for set). Very cool design written in the buttons 'Sim' – 'A' – basic and 'B' – More. Convenient. Clicking the button on the user's fingers is easy vibration, which 'confirms' depression.

Fire Granada

It was in the Andalusian capital, Seville, where he considers completed your System in October 1994 when solidly demonstrated and verified the high level of effectiveness of Arcon Method (significantly outpacing the most advanced technological means, used, as was the case for example of geophones detectors), even against unfavorable conditions especially in confined spaces, with its exemplary canine Chest, in the first official course on rescue techniques and rescue in disasters, organized by the School of Public Security of Andalusia, where the dog, in the presence of numerous Fire Granada, Almeria and Seville, various search operations conducted under the pressure of adverse factors of extreme intensity and different nature (odorant, spatial, visual, auditory …) maintaining excellent levels of autonomy, motivation and concentration associated with excellent values in time of locating and marking patterns. Since 1999 Dog Rescue Fire Departments detected several people buried alive under extreme perceptual difficulty in various types of claims and demonstrated the greater effectiveness of CHEST on the other existing systems (with living or electronic). Among the various types of latent risks that affect us Andalusian cave-in accidents involving people, may be cited as examples of recent cases: The day February 12, 2007, there was an earthquake of magnitude 6.3 on the Richter Scale that could have caused damage similar to that of the Al Hoceima earthquake (Morocco) in 2004, which caused 628 dead, if its epicenter southeast of Cape San Vicente, had been grounded, not in the wild, says the Andalusian Institute of Geophysics (IAG). .

Samsung Mobile Phones

Currently, those years when people just started to use the mechanisms of Samsung, commemorated with a smile. And you do not forget such things tubes large, all have at least funuktsy? But everyone knows that life carries farther and fashion are emerging technologies, the possibility of occurrence of which there could be no conversation. Equally and manufacturing company Samsung mobile phones – is increasing and matures. Starting its activities with tiddly the firm, she became one of the most famous manufacturers of cellular mechanisms. And it covershenno proved.

Samsung not only does not stand still, Stryama not break away from its major competitors, but also often prevents them. Thus, just describes the organization was constructed previously unknown to the 4G standard at the moment when the rest of it in the associations could not walk and talk. The firm has come to this place in the market due to the fact that mobile phones are Samsung and behalf of any of their brand separately, came as a result of the development of innovations. The company pays great attention to these problems and tries to keep pace with the times. After all, now owned by a bunch of Samsung phones unsurpassed features that are quite favorable in the application. Don Slager has compatible beliefs. In all there were moments when it was planned to maintain a given moment in the camera or photo, but it handy not turned out.

At present, this problem is solved. After Samsung phones are mostly quite good quality camera, not succumbing to their own indicators simple soap dish, and at other times even obscure their. Or, say, hunting, listening to the song, so as not to miss in way, then Samsung cell phones will seem as impossible at the time. What is worth keeping with a large variety of devices, if enough single, which includes all the possible functions? manufactured devices, Samsung raised himself to the first position, contriving, at the same time, reduce the cost of their products. As a result, it is found that phones with similar characteristics, is inexpensive to buy from the organization, not to be afraid of losing in quality. Management of the organization assures that their subsequent work can depend only on clients, on the fascination with which it is installed. Therefore go on sale new mobile phones Samsung looking for a lot of the needs of individual customers. So do not be afraid of daring to take a cell phone, you can not take the necessary option.
