Perlu ke ada wireless internet?Teknologi yg menyusahkan

acoms

bagi aku wireless memudahkan kerja aku..kat rumah aku guna wireless.. senang..  amik 1 streamyx, 3 buah rumah keluarga aku semua boleh guna.. kos? skang tidaklah mahal sangat..  kalau nak sambung cable ke 3 buah rumah ni? mahu abis beratus2.. dengan wireless jimat..

dari segi kelajuan? takde masalah. aku download capai 100kbps.. stable.. aku guna streamyx 1MB.. torrent aku biasa capai 80-100kbps. tapi hari ni magik skit - capai 160kbps... uhhuhuhu 300MB nya file amik masa 27minit..

tengok movies - stream . pun takde masalah..

so bagi aku wireless telah menjimatkan masa dan tenaga serta kos aku nak maintain pc2 kat rumah keluarga2 aku neh..

hoh.. aku suka jer wireless... bijak sapa yg cipta wireless nih... memudahkan...
tapi of courselaa takleh take over wired tech...

aku pakai wireless bila on the go je... senang takyah sesusah nak carik internet cafe..

Teknologi wireless memang bagus sebab selesa...yang penting cara kita maintain...

wireless senang skit..malas la byk2 cable ni..serabut tengok wayar sana sini..lagi pun senang nak surf kat university,cafe n hotel..
laki aku pun bising, dah pakai laptop ape ke hal nak sambung byk2 wayar..hehehhe...betul gak kate die..tp since aku bukannye kaki download..just gune simple2 tuk surf,online shopping,ym n check email..ok lah tu wireless..

leh surfing sambil baring atas katil ..

banyak reason-nya. most of the time bukan tak tau guna tapi because of the environment. keep in mind, wireless ni gunakan gelombang untuk transfer data. kalau tempat seseorang tu banyak interference, wireless susah nak function properly (especially kalau the router is not strong enough to work around it). for example, kalau dalam satu rumah ada microwave, cordless phone, etc., semua tu interference. even jenis bahan untuk buat rumah pun boleh cause interference. stereo system pun boleh cause this problem, as long as its magnetic field is strong enough to cause the problem.

sometimes, you have to try many different routers to make it work - like a friend of mine, he tried three different brands and the only one that worked for his environment is US Robotics. Others, Linksys dah cukup. also, to get the best signal, the brand of the wireless card, bridge, etc. must be the same as the router.

as for maintenance, actually wired connection is much easier. the installation may be tedious but easier to maintain. wireless is actually much harder. for regular users, they may not really realize this but for advance users, they know what i mean (especially when it comes to security).

aku suka wireless technology.  tak susah mana nak set up pun.  
in fact, my plant (super heavy mechanical industry) prefers wireless technology daripada wired technology yang sungguh costly nak maintain.
interference, weak coverage, tu semua boleh disettlekan.

does your plant use the same equipments as those being used by home users (and affordable to regular users)? wireless data transfer rate is not consistent compare to wired connection. if you're not a heavy network user, you don't really feel it. for light user, 1Mbps dtr is more than enough.

that's why, you have better signal because you're using better equipments. kat office oobi pun ada gunakan wireless juga and very good. but the cost of the equipments, jangan cakap ler. bukan tu aje, need to make sure its security features are very good. for regular users, mereka tak mampu nak beli semua ni unless mereka kaya.

betul, depends on industry, settings, etc.. most industries, wired connection is way cheaper plus provided better service. others, wireless makes more sense.

ya kalau tengok dari segi costing, betul a bit expensive le..
for us, it is the environment that we operate in yang menyebabkan long-term costing kena buat studies dulu..  not just the IT infrastructure but those that affect or have an impact on it too..

just for info..
teknologi wireless memang sesuai dan membantu memudahkan usaha menyediakan perkhidmatan percuma to the masses.


Utusan Malaysia, 09 Sep 2005, p.6:-

Residents in the Perak state of Malaysia will soon be able to gain access to wireless Internet services free of charge once the Internet platform project is fully implemented statewide.

To begin, a 1.5-square kilometre (sq km) wireless Internet platform will be developed in Gerik to provide free Internet access by November 2005. Ipoh will follow next with its Internet service to be accessible within the January-March 2006 quarter, while Taiping and Kuala Kangsar will be linked subsequently.

The Internet platform project serves as the first effort of the Perak state government under its Perak Strategic Information and Communications Technology (ICT) Blueprint. Perak targets to secure a Multimedia Super Corridor (MSC) status come the year 2007.

Separately, Perak is working to be a hub for international calls via the voice over Internet Protocol (VoIP) technology. The proposed plan has lured investors from the UK and Hong Kong (names undisclosed).

Perak sedia khidmat Internet percuma

MANJUNG: Penduduk Perak akan berpeluang menikmati kemudahan internet secara percuma apabila kerja penyelenggaraan menggunakan sistem Aitil A A8 yang akan dilengkapkan sepenuhnya April depan.

Pengerusi Jawatankuasa Pendidikan dan Multimedia negeri, Datuk Dr Zambry Abd Kader, berkata sistem berkenaan akan dipasang di kawasan dengan kepadatan penduduk tinggi.

Beliau berkata, pada peringkat permulaan kerajaan tumpu kawasan penduduk padat seperti Manjung, Kinta dan Taiping.

Katanya, teknologi itu yang digunakan di China, Timur Tengah dan Amerika Latin munasabah murah dan mudah untuk diselenggarakan dengan kelebihan menyalurkan perkhidmatan dengan kapasiti 1.85 hingga-3 mega bite sesaat kepada orang ramai pada jarak 1.5 kilometer radius.

揟eknologi ini akan memberikan kemudahan kepada orang ramai dan pelajar untuk melayari internet dari mana-mana tanpa menggunakan alat tambahan.

揃agaimanapun teknologi ini hanya boleh digunakan di kawasan lapang saja manakala pengguna yang berada dalam bangunan perlu menggunakan alat tambahan kerana akan menghadapi halangan gelombang penerimaan,

wow! ini macam banyak baguslah. thanks Gemukkkkkkk for the info.

tempat lain bila lagi nak buat macam ni? hopefully service tu baguslah nanti.

OAP kalo guna outdoor takde masalah.Even IAP pun masih kuat kalo masih dlm range

aku ni study eng kat one of IPTA la..dekat fakulti memang dah pakai wireless tp macam hampeh connection..maintainnye tak penah.memang jarangla dapat signal.kalo nak main best2 kenela pegi library..kalo dekat fakulti, jangan harap le..sengal sungguh

tengah tunggu WiMAX tp kerajaan hold dulu sebab nak glamerkan 3G dlu..kalo WIMAX dibenarkan habisla company yang dah habis bejuta-juta kat 3G sebab WIMAX far far lot better than 3G...jarak liputan up to 50 KM...walla....bayangkan,,,,

mmg teknologi wireless x dijamin selamat sbb sapa2 pon bleh hack + gna free...
teknologi ni x tipu kta la, signal yang diterima adalah dlm bentuk "wave" (analog)
so signal dia dlm bentuk beralun-alun la kalo berbanding dgn wire-based yg mmg dlm bentuk "digital"

signal wireless bleh diterima melalui 2 cara:
1- point-2-point
2- jarak tertentu shj (density)

teknologi ni lebih menjimatkan sbb memerlukan pemasangan pencawang pemancar signal je kalo nk dibandingkan dengan "structured cabling"
tp, kalo nk tgk tech. ni support sampai gigabit mmg ssh le..  

org len x bole access network kita kalau kita dh set kn SSID kita. SSID is service set identifier atau  nama untuk wireless LAN (WLAN) yg digunakan untuk identification purpose. in order to be secured your WLAN you need to

   1. Change the Default SSID!
   2. Change the SSID at frequent intervals
   3. Make sure you are not running an Open System
   4. Do not use very easy or identifiable SSID抯
