GPRS (Kecepatan Akses Internet-GPRS)

Tentu Anda mengenal handphone (HP) bukan..?
Nah pada hari ini viandragaulz ingin berbagi pengetahuan tentang Gprs Handphone.Kebutuhan industri akan komunikasi bergerak menyebabkan GPRS menjadi salah satu teknologi komunikasi data yang banyak digunakan saat ini. GPRS adalah kepanjangan dari General Packet Radio Service yaitu komunikasi data dan suara yang dilakukan dengan menggunakan gelombang radio. GPRS memiliki kemampuan untuk mengkomunikasikan data dan suara pada saat alat komunikasi bergerak (mobille). Sistem GPRS dapat digunakan untuk transfer data (dalam bentuk paket data) yang berkaitan dengan e-mail, data gambar (MMS), dan penelusuran (browsing) Internet. Layanan GPRS dipasang pada jenis ponsel tipe GSM dan IS-136, walaupun jaringaan GPRS saat ini terpisah dari GSM. Dalam teorinya GPRS menjanjikan kecepatan mulai dari 56 kbps sampai 115 kbps, sehingga memungkinkan akses internet, pengiriman data multimedia ke komputer, notebook dan handheld computer. Namun, dalam implementasinya, hal tersebut sangat tergantung faktor-faktor sebagai berikut: Konfigurasi dan alokasi time slot pada level BTS Software yang dipergunakan Dukungan fitur dan aplikasi ponsel yang digunakan Ini menjelaskan mengapa pada saat-saat tertentu dan di lokasi tertentu akses GPRS terasa lambat, bahkan lebih lambat dari akses CSD yang memiliki kecepat 03.d. 3G (Kecepatan Akses Internet-3G) 3G (dibaca: triji) adalah singkatan dari istilah dalam bahasa Inggris: third-generation technology. Istilah ini umumnya digunakan mengacu kepada perkembangan teknologi telepon nirkabel (wireless). 3G sebagai sebuah solusi nirkabel yang bisa memberikan kecepatan akses: Sebesar 144 Kbps untuk kondisi bergerak cepat (mobile). Sebesar 384 Kbps untuk kondisi berjalan (pedestrian). Sebesar 2 Mbps untuk kondisi statik di suatu tempat. Jaringan 3G tidak merupakan upgrade dari 2G; operator 2G yang berafiliasi dengan 3GPP perlu untuk mengganti banyak komponen untuk bisa memberikan layanan 3G. Sedangkan operator 2G yang berafiliasi dengan teknologi 3GPP2 lebih mudah dalam upgrade ke 3G karena berbagai network element nya sudah didesain untuk ke arah layanan nirkabel pita lebar (broadband wireless). Jaringan Telepon Telekomunikasi selular telah meningkat menuju penggunaan layanan 3G dari 1999 hingga 2010. Jepang adalah negara pertama yang memperkenalkan 3G secara nasional dan transisi menuju 3G di Jepang sudah dicapai pada tahun 2006. Setelah itu Korea menjadi pengadopsi jaringan 3G pertama dan transisi telah dicapai pada awal tahun 2004, memimpin dunia dalam bidang telekomunikasi. an 9,6 kbps. 03.e. Wifi (Kecepatan Akses Internet-WiFi) Pernahkan kalian melihat sambungan komunikasi tanpa kabel? Teknologi itu dikenal dengan Wirelless Fidelity (WiFi). Teknologi jaringan tanpa kabel menggunakan frekuensi tinggi berada pada spektrum 2,4 GHz. Wi-Fi memiliki pengertian yaitu sekumpulan standar yang digunakan untuk Jaringan Lokal Nirkabel (Wireless Local Area Networks - WLAN) yang didasari pada spesifikasi IEEE 802.11. Standar terbaru dari spesifikasi 802.11a atau b, seperti 802.16 g, saat ini sedang dalam penyusunan, spesifikasi terbaru tersebut menawarkan banyak peningkatan mulai dari luas cakupan yang lebih jauh hingga kecepatan transfernya. Wi-Fi (Wireless Fidelity) adalah koneksi tanpa kabel seperti handphone dengan mempergunakan teknologi radio sehingga pemakainya dapat mentransfer data dengan cepat dan aman. Wi-Fi tidak hanya dapat digunakan untuk mengakses internet, Wi-Fi juga dapat digunakan untuk membuat jaringan tanpa kabel di perusahaan. Karena itu banyak orang mengasosiasikan Wi-Fi dengan “Kebebasan” karena teknologi Wi-Fi memberikan kebebasan kepada pemakainya untuk mengakses internet atau mentransfer data dari ruang meeting, kamar hotel, kampus, dan café-café yang bertanda “Wi-Fi Hot Spot”. Juga salah satu kelebihan dari Wi-Fi adalah kepraktisan,tidak perlu repot memasang kabel network. Untuk masalah kecepatan tergantung sinyal yang diperoleh.

Turbulent times in year of tiger:soothsayers

HONG KONG — US President Barack Obama's fortunes will sink further and nuclear threats will grow, but the world economy will bounce back in the turbulent Year of the Tiger, Chinese soothsayers predict. "Obama will start going downhill this year. He will not be able to achieve much," said Peter So, one of Hong Kong's celebrity feng shui masters peering into the future as the Lunar New Year rolls around on Sunday. Chinese fortune-tellers study the changing balance of the five elements they believe form the core of the universe -- metal, wood, water, fire, and soil -- and in the Chinese zodiac the tiger is seen as the mother of fire. In feng shui, a person's element can be calculated by using the exact time and date of his birth. Obama, born in the summer of 1961, needed the support of water and did not go well with fire, So said. "Unfortunately, there is too much fire and no water for Obama this year." He predicted that already strained Sino-US relations would deteriorate further in the second half of 2010, with Obama's good fortune running out. Other leaders could also be in for a hard time, according to their place in the 12-year cycle of animals which appear in the Chinese Zodiac -- Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog and Pig. Monkey is the least favourable animal sign this year as it is in a direct clash with the tiger, according to the soothsayers. UN Secretary General Ban Ki-moon, who was born on the Day of the Monkey in the Year of the Monkey, is expected to experience a particularly rough 2010, Raymond Lo, a Hong Kong feng shui expert, told AFP. Others born in the Year of the Monkey include Akio Toyoda, chief of troubled Japanese auto giant Toyota, and Hong Kong leader Donald Tsang, who has been dogged by growing public discontent. The tiger's link to fire could also be a warning of renewed nuclear threats from rogue regimes such as North Korea and from terrorists, Lo said. Adding to the possibility of troubled times is the fact that metal is the dominant element this year. "Unfortunately, this means the year 2010 will not be peaceful as there will be lots of international conflicts," Lo told AFP. Each element is further divided into the yin and the yang strands, the two complementary qualities representing nature's passive and active side. Lo said that metal this year belongs to the yang strand and is a symbol of loyalty to friends and justice. "However, these seemingly positive qualities can be destructive to international relations as state leaders may take sides and make military alliances." But the disputes were unlikely to result in violence, he said. On the positive side, fire symbolises the driving force of the economy and lifts hopes that a long-term recovery will be in sight, feng shui masters said. "Fire stands for optimism and a speculative mentality, which means that there will be lots of activity in the stock market this year," said Lo. "We've got to remember that the financial crisis was triggered by the absence of fire and prevalence of water, which symbolises fear." Feng shui master Alion Yeo predicted that stock markets in Hong Kong and China would be up at the beginning of the year. "But it will experience significant fluctuations around August before the market rebounds for a sustainable recovery towards the end of the year," he said. The experts believe that the Year of the Tiger will also be favourable to industries connected to metal, such as banking, machinery, high tech, and cars. While they had varied predictions on what sort of natural disasters the world will see in a year dominated by metal and fire they all agreed on one thing -- an abundance of traffic accidents.

Alexander mMcQuen "jenius" or just charismatic

Reading the reports of Alexander McQueen’s death you would think we had lost an Oscar Wilde or a Jimi Hendrix. “He was a genius,” says Katharine Hamnett. “What a terrible tragic waste.” “His brilliant imagination knew no bounds,” says Vogue editor Alexandra Shulman. I’m always skeptical when the word “genius” is bandied about by the fashionista — more or less everything is “genius” in their world, as in, “Love that belt, darling. It’s genius.” I oversaw an Alexander McQueen fashion shoot for Vanity Fair’s Cool Britannia issue in 1997 (styled by Isabella Blow) and the thing that really stood out was the cult of personality he had managed to create around himself. He wasn’t a conventional Alpha male, but he was one of those people who used his shyness as a weapon — a form of passive aggression. When he finally appeared on set, at least two hours late, he was surrounded by flunkies and skulked around at the edges of where the models were posing, radiating hostility. The impression he gave was that participating in a photo shoot for Vanity Fair — a privilege that would vastly inflate the amount of money he could extract from credulous advertising agencies — was a colossal chore, far beneath his dignity. He was a rock star. Everyone else was a groupie. As a mere employee of the magazine that was paying him tens of thousands of dollars to secure his services I wasn’t entitled to speak to him. Instead, all communication had to be relayed through some ghastly major domo — a sort of Osric figure. Nine times out of ten, I would pose a question — “Is it okay if we pin the dress at the back because, er, it doesn’t quite fit?” — and get no reply. At the time I resented this, but after I become a bit more worldly — several fashion shoots later — I realised that McQueen’s behaviour was inextricably bound up with his reputation. Had he been a little less prima donna-ish, he never would have become acclaimed as the Greatest Living Designer in British fashion. It took a while, but I finally realised that there’s no such thing as talent in fashion — at least, not in the sense in which it’s normally understood. Unlike literature or music, it simply isn’t clear which designer has talent and which hasn’t. One person puts together a collection in which the models appear in dustbin liners, another in which they’re sporting sackcloth, and who’s to say which collection embodies the “zeitgeist”? To the outsider, both collections look equally idiotic. Before I become involved in this world, I assumed that the reason I couldn’t tell which designers were good and which mediocre was because I lacked experience — I didn’t have any “taste”. But after working in fashion for several years, I realised that “taste” is just a euphemism for the collective wisdom of the fashion elite. And their standards change from week to week — sometimes day to day. Clearly, there were no hard and fast rules, no “canon” which the arbiters of fashion could refer to. So what dictated who was “in” and who was “out”? What prompted the grandees of the fashion world — Anna Wintour, Suzy Menkes, Grace Coddington — to declare one designer a “genius” and another “so ten minutes ago, darling”. It’s not just one thing, obviously. Up to a point, you can tell which designers possess some creative flair — and McQueen clearly had that in spades. Originality counts for something, too, provided it’s within the acceptable parameters. Technical skill — “craft” — is also something the Lord High Executioners of the Catwalk like to cite from time to time, pretending they know something about the stitching techniques used in Indonesian sweatshops. But, overwhelmingly, it’s about the charisma of the designer in question. How much force of personality does he or she possess? Typically, a top designer secures an audience with the high arbiters of international style before he unveils his collection and that is his chance to impose himself, to convince the panel of judges that he’s in possession of some supernatural connection to the sturm and drang of contemporary culture. How does he do this? Sometimes by being emphatic and stern-faced, like Karl Lagerfeld: “Achtung! Achtung! Pink is the new blue.” But it’s often more effective to be quietly confident, shy yet sure. You pronounce with total conviction that, for instance, skulls on scarves are going to be Next Big Thing, and the skull-faced Sybils nod along with great sagacity. The lower the volume, the more convincing the case. Not much to do with talent; mainly to do with personal charisma. So that’s my verdict on Alexander McQueen. Not a “genius”, unless by that you mean a gift for self-presentation. But someone who managed to survive at the top of a very competitive game for over 10 years through sheer force of personality.
