Kita seringkali menggunakan jaringan internet setiap harinya. Ada yang menggunakan kartu modem, ada juga yang konek internet melalui wifi dirumah atau kantor. Nah ketika di kantor pasti sudah banyak yang menggunakan jaringan internet dengan wifi. Kita bisa mengakses internet melaui wifi di laptop kita. Kita bisa mengerjakan pekerjaan online bisa dengan wifi tersebut. Enak kan jika ada wifi disekitar kita ? Kita bisa mengakses internet dengan mudah jika ada jaringan wirelessnya. Namun kita jangan asal menggunakan saja. Alangkah lebih baik jika kita bisa mengerti sejarahnya. Sebenarnya apa sih wifi itu ? dan asal mulanya bagaimana wifi bisa tercipta.
Apa Sih Wi-Fi itu ?
Wi-Fi merupakan singkatan dari Wide Fidelity. Wide artinya luas dan fidelity artinya ketepatan atau kejituan. Namun begitu digabung menjadi Wi-Fi, istilah tersebut artinya bukan ketepatan yang luas. Belakangan ada juga yang memanjangkan Wi-Fi sebagai wireless fidelity. Yah cara singkat pengertiannya sih koneksi tanpa kabel gitu aja hehe.
Wi-Fi merupakan teknologi jaringan komputer yang tidak mengandalkan sambungan kabel. Teknologi ini sepenuhnya mengandalkan gelombang radio untuk menghubungkan jaringan tersebut. Pada perkembangannya Wi-Fi banyak digunakan untuk menikmati jaringan internet dengan biaya relatif lebih murah dibanding jaringan kabel.
Sejarah Wi-Fi
Kita layak untuk berterimakasih pada penemu wifi ini. Karena sampai saat ini wi-fi banyak sekali digunakn para user untuk bekerja, main game dan lain lain. Perkembangan Wi-Fi ini dimulai dari ditemukannya penggunaan gelombang radio secara ilegal di Amerika pada tahun 1985 oleh Federal Communications Commision. Kemudian pada tahun 1991 seorang ahli bernama Vic Hayes dari perusahaan bernama Lucent & Agere System (sebelumnya bernama NCR Corporation/AT&T) mengembangkan gelombang radio ini untuk sistem pembayaran di kasir di Nederland, Belanda.
Temuan Wi-Fi ini kemudian disempurnakan oleh sekumpulan insinyur dari perusahaan komputer dan jaringan raksasa di dunia bernama Institute of Electrical dan Electronics Engineers (IEEE). Dengan adanya Wi-Fi kita menjadi lebih mudah untuk bisa menikmati internet.
Kelebihan Menggunakan Wi-Fi
– Wi-Fi dikembangkan tanpa kabel dan menggunakan gelombang radio dengan frekuensi 2,4 GHz. Selain itu
Wi-Fi dapat mengirim dan menerima kapasitas sampai 54Mbps.
