WiFi 802.22 Technology Promises Wireless Data Over 60 Miles: Say Goodbye to Data Plans

It’s the news bit you’ve been waiting years to hear! The folks at the IEEE standards body have today announced a next-generation WiFi IEEE 802.22TM standard – technology that’s designed to facilitate wireless data transfer up to 60 miles (or a hundred kilometers) at 22Mbps. This technology is said to work over these great distances by utilizing television bands – without interfering with the reception of existing television broadcast stations at that. Imagine it – connect to your HambergerDLX network anywhere inside your town from your smartphone with no data plan costs. Magical freedom!


This technology takes advantage of VHF and UHF TV bands and transmits broadband wireless internet over 60 miles in diameter. This technology takes place in the space between channels, aka the place where the poltergeists live, if you believe technology lore. The officials at the IEEE standards body have noted the following about this new age in wireless technology:


This new standard for Wireless Regional Area Networks (WRANs) takes advantage of the favorable transmission characteristics of the VHF and UHF TV bands to provide broadband wireless access over a large area up to 100 km from the transmitter. Each WRAN will deliver up to 22 Mbps per channel without interfering with reception of existing TV broadcast stations, using the so-called white spaces between the occupied TV channels.

IEEE, the world’s largest professional association advancing technology for humanity that is, noted that this technology will be “especially useful” in less densely populated areas, developing countries, and other locations where most vacant television channels can be found. They’re there – let’s use em!

What if it’s true? It seems much, much too good to be true, doesn’t it? It’s the inexpensive means of getting data we’ve always dreamed of. Just think of only spending $60 a month (or however much it costs near you) for data both in and outside your home, unlimited data, data you’d otherwise have to pay twice as much for on a network that might just as well be cut out of the equation altogether? The facts are here, the news release is plain and simple, but something tells me this tech might never see the light of day – what do you think?

Perlukah Jailbreak iPhone / IOS Device?

Sebelum saya menjelaskan lebih lanjut perlu atau tidak perlu untuk jailbreak iphone/ ios device, elok saya jelaskan apa itu JAILBREAK.

Jailbreaking IOS adalah suatu proses yang membolehkan peranti yang menjalankan IOS Apple (juga dikenali sebagai OS iPhone sebelum IOS 4.0) sistem operasi (seperti iPhone, iPad, iPod Touch, dan baru-baru Apple TV) untuk mendapatkan akses penuh (akses root) untuk membuka semua ciri yang dimiliki sistem operasi, sehingga menghapuskan had-had yang ditetapkan oleh Apple. Setelah Jailbroken, pengguna IOS boleh men-download tambahan aplikasi, sambungan dan theme yang tersedia melalui rasmi Apple App Store, melalui installer seperti Cydia, salah satu daripada sejumlah sarana saat iPhone yang lebih tua. Sebuah iPad iPhone, Jailbroken atau iPod Touch IOS berjalan masih boleh menggunakan App Store dan iTunes dan fungsi normal yang lain, seperti membuat panggilan telefon. Jailbreaking serupa dengan perakaran peranti Android.

Pada intinya, jailbreaking peranti memberikan akses kepada sistem fail root, yang membolehkan pengubahsuaian dan memasang komponen software pihak ketiga. Hal ini memberikan kawalan pengguna lebih atas peranti dan membolehkan ciri-ciri yang sebelumnya tidak tersedia tanpa jailbreaking.

Jailbreak ini bergantung kepada keperluan sahaja dan tidak menjadi suatu kemestian bagi sesuatu IOS device. sebenarnya jailbreak ini mendedahkan iphone/ipad/ipod atau apa-apa ios device kepada risiko yang banyak. Antaranya serangan virus,spyware, malware dan iphone jadi slow serta banyak lagi risiko yang bakal mengundang.

Jailbreak juga akan menyebabkan iphone anda akan kehilangan warranty (Warranty Void), tapi anda boleh restore balik kepada keadaan baru untuk claim warranty. tapi anda kena ingat, sekiranya iphone anda selepas jailbreak langsung tidak boleh ON/OFF, maka bagaimana anda nak restore IOS tersebut? dan semestinya anda akan sukar untuk claim warranty.

keperluan kita di Malaysia juga berapa menggalakkan kita untuk jailbreak IOS kerana kebanyakkan aplikasi yang dimasukkan perlu di crack terlebih dahulu. cracker masih tidak ramai di Malaysia dan software yang terkini selalunya lambat di crack dan kita akan selalu mendapat software yang versi awal. misalnya PAPAGO versi malaysia selalunya cracker dari luar malaysia tidak berapa gemar untuk crack software tersebut dan kita tidak boleh dapatkan software crack tersebut dalam pasar gelap Installous.

tambahan pula, kebanyakkan software yang di tawarkan dalam AppStore hanya sekitar $0.99 dan jika convert duit Malaysia pun baru sekitar RM3-RM4 sahaja.
