GSM Vs. CDMA Cellular Phones and the Benefits of Each

In terms of cellular service, there’re 2 technologies competing in the market right now. They are GSM, i.e. Global System for Mobile Communications, and CDMA, i.e. Code Division Multiple Access. Cellular carriers inclusive of Verizon, Sprint PCS, Cingular Wireless, and T-Mobile make use of one of these two technologies. Comprehending difference between CDMA and GSM would simplify the way of choosing a carrier which utilizes the network technology preferable for your needs.
GSM association can be referred to as one of the international organizations founded in the year 1987, which is dedicated toward the provision, development, and overseeing of GSM standard across the globe. CDMA is amongst the proprietary standards designed by a company called ‘Qualcomm’ in the US. It has been dominant with regards to network standards for certain Asian countries and the whole of North America. GSM networks, however, continue making roads in US. There’re camps on every side, which think of CDMA or GSM to be superior to another. All said and done; the non-invested customer who just wants the bottom-line information for making a choice, the considerations given below might turn out to be useful.
Coverage
The most essential factor is that of getting proper service in areas where phone would be used. Upon having viewed coverage maps of competitors, you might discover that only CDMA or GSM carriers make cellular service available in the area that you need it. If that is the case, there won’t be much of a choice.
Speed of data transfer
As cellular phones are performing double, triple duty in the form of streaming video plans, email devices, and pod cast receivers, speed is vital for the people who make use of phone for other purposes, apart from making calls. It is a known fact that CDMA Cell Phones are faster as compared to GSM Cell Phones. Both can boast of third generation technologies, or 3G standards.
SIM (Subscriber Identification Module) cards
In the US, SIM cards are used by GSM phones only. SIM card, that have the ability of getting removed, permits the cell phones to get activated, swapped out, interchanged, and upgraded, without the intervention of a wireless carrier. The SIM here, gets tied to a network, in place of the actual phone. Card-enabled unlocked phones can be utilized with any carrier of GSM.
CDMA equivalent, the R-UIM card, has been made available in certain Asian countries since the last few years. It’s, however, on horizon for market of the US. Carriers of CDMA in US need proprietary handsets. They are connected to a single carrier and aren’t card-enabled. For upgrading any of the CDMA phones, carrier should deactivate the old phone and then have the new one activated. Old phone turns out to be useless most of the time.
Roaming
Both the networks have a fairly wide coverage in main cities, along with main highways. Carriers of GSM have contracts of roaming with the other carriers of GSM, thereby permitting broader coverage in rural areas, in particular. CDMA networks might not have rural areas covered as effectively as GSM. They might sign a contract regarding roaming with the GSM cells for coverage in rural areas, but the customer would then have to shell out a bit extra.

What does 3G mean?

Nowadays, everybody has a mobile phone. Whether they're on a contract or a pay as you go tariff, the mobile phone has become an essential item for many people. this article will be taking a look at the the mobile phone's history - as well as its future - in order to find out more about the now essential telecommunications device.

Mobile phones started life as the two way radio, which was also called mobile rigs. these were installed in vehicles such as minicabs, police cars and ambulances, but were not strictly mobile phones as they were not normally connected to the telephone network. while the very first mobile phones were installed permanently in vehicles, later versions such as the transportables, also called bag phones, could also be carried, and can be used as either portable or as mobile two-way radios.

The first generation of mobile phones are often called 1G. These mobile phones are the analog devices that were introduced in the eighties & continued until being replaced by 2G mobile phones, which ran on digital networks. in fact, even though 1G & 2G systems use digital signals to connect the radio towers to the rest of the telephone network, the voice itself during a phone call encoded to digital signals in 2g while voices on 1G phones aren't.

Second generation, also called 2-g, mobile telephones were introduced in the nineties. 2-g phone systems were characterised by their use of digital transmission and the introduction of advanced and fast phone to network signalling.

The birth of 2-g systems saw telephones move from friendly 1g telephones to little handheld items, which were much more portable. this change was possible through technological developments including more advanced batteries and energy saving electronics.

The second generation mobile telephones had severaladvantages over 1g items. These included text messaging, which became possible on gsm networks initially and eventually on all digital networks. the earliest machine-sent message was sent in 1991 in the uk. the earliest person to person sms text message was sent in 1993 in finland. sms text messaging soon became the preferred method of communication and the public now prefer sending text messages to placing voice calls.

3-g is the term applied to the third generation of mobile phone standards & technology. 3g follows 2g mobile phone technology.

The birth of 3-g technologies allow network operators for instance Vodafone give their users a larger range of more advanced services. These include video calls& wireless internet.

Even though 3-g was successfully introduced throughout the world, issues have been raised by both 3-g providers & users, comprising of costly phones. in addition to this, there's numerous differences in the licensing terms.

Ever since the launch of 3-g mobile phone technology. people have been talking about 4g. 4g technology will signify the future of mobile telephones, creating the most sophisticated handsets and best services yet. in actual fact, one of the next services to be developed is thought to be live streaming of radio and tv shows to 3-g handsets is and shops including real and disney recently announcing that they'll be offering services like these.

In conclusion, even though the history of mobile phones they have come a long way in the past few years, it also indicates that they'll go even further still.

Did i choose the best Laptop Computer ?

Did I choose the best laptop ?

Keys to choosing the best laptop computer :

Who is the laptop user? When choosing a laptop computer, it is important to understand who will be using it.., school student, college student, professional businessman ,office worker, etc.

Where will the laptop be used? For heavy mobile users such as college students and professionals, size, weight and battery life are very important. So when looking over the reviews and relevant specs, keep those factors in mind. The average high school student uses a laptop from room to room in their house, and have loads of access to AC power most of the time. So for these users, the factors listed above may not be as critical.

How will the laptop be used? The more mobile the user, the more durability is needed. Heavy users ie sales reps spend a great deal of time start and shutting down their laptops every day. an average heavy user will open and shut their laptop computer 5 times a day. Although that may not seem alot of wear and tear, there is also the issue of general handling. Heavy users will be travelling from location to location, in and out of cars,on and off planes etc on a constant basis. This increases the likelihood of damage to the laptop computer, via dropping, bumping and banging, drink spills on the keyboard, etc....

Should I buy a service contract for my laptop? the answer is YES. When you think about carrying around a fragile piece of electronics costing $1000 or more, the price of a typical service contract is a bargain. for a relatively small price $100 per laptop computer, its worth it to for you peace of mind.

.How much should I expect to pay for a laptop? It used to be hard to find a quality laptop under $600; however, this is no longer true. There are several companies with great offers, starting around £300. The options / upgrades you select have a large impact in what you can expect to pay. Having a list of what you want in a laptop, such as memory, speed, hard drive size, burners, etc..will help when you go shopping. Although online laptop computer manufacturers allow a great deal of customization, the general public are easily serviced with a “off the shelf” standard laptop computer.

What Laptop Brand Should I Select? the worlds your oyster in this respect with the amount of laptop computer manufactures out there,with different colours and sizes its everyones personal choice , I myself find that acer have all the features which service my needs.

Apa Hebatnya Blackberry..........?

Push Email
Blackberry boleh disebut sebagai pioner dalam push email. Email push sama dengan email biasa yang sudah kita kenal, cuma cara penyampainnya tidak perlu di download, melainkan ketika di kirim, email langsung tiba seperti SMS.
Sebagian besar orang yang memiliki email, membaca email secara berkala, misal
di kantor, atau ketika di rumah waktu pulang kerja. Dengan cara manual ini, seringkali beberapa email penting tidak bisa ditanggapi dengan cepat.
Push email (email dorong) ini, tidak memerlukan pengaturan yang rumit. Pengguna bisa mendaftarkan 10 alamat email dan untuk mengaturnya hanya perlu memasukan alamat email serta password, tanpa dipusingkan dengan konfigurasi GPRS, POP3, SMTP, dll.

Sarana Sosialisasi
Push email tidak melulu hanya urusan pekerjaan, tetapi juga menyenangkan untuk sosialisasi. Banyak sekali sekarang mailing list yang punya segmen khusus, misal mailing list teknologi, mailing list kuliner, mailing list trading, dan lain-lain. Mailing list yang diangkat sebagai milis, ini memungkinkan orang-orang yang punya minat serupa, berkumpul di ruang maya, dan saling berbagi informasi pada bidang yang di minati.
Beberapa milist memiliki sejumlah peserta yang banyak, dan jumlah email per hari nya yang ratusan email. Jika kita mengikuti beberapa aja milis yang emailnya ratusan per hari, bayangkan ketika kita membacanya di rumah sehabis pulang dari kantor. Dengan push email, kita bisa "mencicil" membaca email yang masuk, bisa ketika kita sedang sarapan pagi, ketika kita sedang menunggu anak pulang sekolah, atau ketika mengantri, dan sebagainya.

Manajemen Email
Beberapa email dapat ditampung sebuah Blackberry yang "hanya" memiliki 64MB data storage/memory internal? puluhan ribu email dapat ditampung dengan kapasitas hanya sebesar itu dengan mudah. Ini disebabkan sistem kompresi Blackberry yang luar biasa. Biasanya email kita yang di download manual ke PC berkisar 3 - 6kb per email. Pada sebuah Blackberry email yang sama di kompresi sampai seperseratusnya.
Data email yang ribuan tentu saja memerlukan manajemen email yang baik, karena email yang terlalu banyak jarang bisa di baca 100 persen. Mudah saja kita kehilangan email penting dari rekanan atau atasan, karena tenggelam dalam ribuan email lain.
Pada Blackberry bisa diterapkan sistem filter yang canggih, email yang penting bisa diset sebagai level 1 message. Dengan ini email penting akan berwarna merah tebal, dan bisa berbunyi dengan nada yang berbeda. Sehingga dari nada panggil nya, kita dapat mengetahui asal email penting tersebut.
Dengan keleluasan memberikan tempat untuk 10 alamat email, maka pada Blackberry kita juga akan memiliki 10 kotak penyimpanan email, ini berguna seperti memilah-milah surat.

Layanan Chatting
Jika dirasa email masih kurang cepat, pada layanan Blackberry, kita juga dapat menikmati chatting. Chatting singkatnya seperti kita bercakap-cakap, tapi dengan bahasa tulisan, yang bisa berlangsung intens tanpa jeda. Dari mulai Yahoo Mesengger, Google Talk, MSN, AOL. Percakapan juga bisa kita langsungkan bukan hanya berdua, tapi bisa beberapa orang sekaligus, seperti konfrensi.
Sudah biasa dengan layanan chatting di atas, kita bisa menikmati layanan chatting yang lebih advance, yaitu Blackberry Messenger, yang banyak disingkat oleh pemakainnya dengan BBM.
Walau mirip dengan chatting lainnya diatas, BBM selain bisa mengirimkanpercakapan melalui tulisan, bisa juga mengirimkan voice note, berupa rekaman suara singkat, yang bisa didengarkan oleh pemilik Blackberry yang dituju. Jadi percakapan di langsungkan seperti layaknya sebuah walkie talkie. Pengirim merekam suaranya, dan mengirimkannya langsung ke penerima. Layanan ini miripdengan yang dikenal dengan push to talk.
Fitur lain yang utama selain push email dan chatting yang di miliki Blackberry adalah fitur browser ke internet. Browser Blackberry selalu online, jadi ketika kita mau surfing internet, dimana saja kita bisa surfing. Beberapa fitur yang tidak atau belum di miliki Blackberry, banyak di bantu oleh fitur browser ini.
Dari urusan penting seperti mencari spesifikasi barang, ensiklopedia, jurnal, dan lain-lain, sampai ke urusan remeh temeh ada di internet. Misalkan kita butuh kamus bahasa Inggris-Indonesia, yang belum ada softwarenya di Blackberry, maka kita bisa langsung buka internet browser dan cari online arti kata tertentu disana. Hampir semua data umum yang diperlukan bisa kita cari via internet browser di internet, termasuk jadwal Kereta Api.

Fitur Map
selain tiga fitur utama tersebut Blackberry "push email, chatting, browser internet", Balckberry masih mempunyai fitur unggulan, seperti Blackberry Maps dan Google Map. Dengan fitur ini, kita bisa melihat map atau peta berbagai kota di seluruh dunia. Dengan bantuan Google Map, kita bisa melihat map berupa foto satelit daerah kita. Berbeda dengan device lain yang kebanyakan data map disimpan dalam unit, pada Blackberry data tersebut di kirimkan melalui sambungan GPRS.

Mengamankan Koneksi Nirkabel

Bila kita sering berpergian ke tempat yang jauh, mejelajahi dunia maya via
akses nirkabel di hotspot membutuhkan pengamanan. Tujuannya agar perjalanan
bisa berlangsung aman dan nyaman.
Meskipun perjalanan ke dunia maya via akses nirkabel tidak akan membahayakan
hidup Anda, ancaman yang dikandungnya masih berpotensi melahirkan masalah bagi
komputer dan data yang tersimpan di dalamnya. Sebenarnya hal ini dapat di cegah
dengan menerapkan beberapa langkah praktis. Yang penting, Kita selalu disiplin
melakukan pengamanan ini manakala sedang mengakses internet di berbagai tempat
umum.

1. Hindari mengirim informasi penting
Camkanlah bahwa segala yang Anda ketik atau segala info yang tampil pada layar
komputer Anda saat mengakses jaringan nirkabel dapat dilihat juga oleh orang
lain. Hal ini khususnya terjadi jika koneksi yang dilangsungkan dalam 'hotspot'
tidak memiliki pengamanan apapun. Ingatlah untuk selalu waspada. Dalam situasi
seperti itu, ada baiknya jika Anda melakukan aneka transaksi online yang
memunculkan aneka informasi penting.

2. Pastikan untuk mengakses protokol HTTPS
Seandainya terpaksa melakukan transaksi online dalam jaringan nirkabel,
pastikan bahwa situs Web yang dikunjungi telah memiliki pengamanan berupa
https. HTTPS (Hypertext Transfer Protocol over Secure Socket Layer atau HTTP
over SSL) merupakan protokol Web yang akan menyandikan setiap informasi yang
dikirim ke atau didatangkan dari server Web.
Namun ada beberapa kasus, protokol https hanya dijalankan pada saat Anda login
ke situs Web. Pada saat proses validasi selesai dilakukan dan kita memasuki
situs web tersebut, protokol yang dipakai biasanya kembali ke http (Hypertext
Transfer Protocol). Hal ini biasanya terjadi saat kita mengakses e-mail via
Webmail.

3. Hindari pengitip di sekitar Anda
Jika mengakses internet dari hotspot di kafe atau tempat umum lain, Anda akan
di kelilingi oleh berbagai macam orang dengan berbagai sifat dan kepentingan.
Ada yang baik, dan tidak berniat buruk, tetapi banyak juga yang jahat dan
berniat tidak baik. Karena itu, pastikan bahwa setiap informasi yang di ketikan
tidak mudah dilihat orang dari meja di belakang Anda, atau dari samping kanan
dan kiri Anda.

4. Pasang "firewall" dan antivirus
Jangan lupa untuk memasang antivirus dan firewall personal dalam komputer Anda.
Dengan kedua benteng tersebut, setiap paket yang masuk atau keluar dari dan ke
komputer Anda akan mengalami proses pendeteksian terlebih dulu. Dengan
demikian, setiap "kuda troya"/penyusup yang berpotensi menembus komputer Anda
akan bisa dicegah.
