bende ni extender/repeater/booster. bende lelain tapi fungsi sama.
kena sambung dgn router yg ada fungsi In-Out. MiMo atau SiMo atau MiSo macam yg penguin explain kat page 1.

kalu la sapa2 pasang mende ni, 1 taman perumahan akan dpt signal (ukuran radius) .
tapi router kene power le...

cuba tengok ni (harga RM) : http://www.lelong.com.my/Auc/Lis ... _share_streamyx.htm
konsep sama je.
yg putih kotak tu utk router (transmit).
antena kecik yg kat bawah tu utk receiver.

aku baca tak payah pakai router (unless dalam umah pon nak jadikan wireless)
kire complete solution la ni

yg mana lagi bagus..yg kat ebay tu ke kat lelong

yg kat ebay tu boleh guna outdoor... kat lelong tu nampak cam bukan weatherproff je

link pertama yg mana satu ni?

ebay tu utk outdoor. kena guna surge protector.
tapi kos dia belum campur router yg mampu guna antena tu. tak semua router buleh guna antena tu.
lelong punya tu indoor. bangunan bertingkat2 sesuai la guna.

yg penting, ko nak kuatkan penerimaan signal dlm rumah.
so, antena yg ko nk pakai mesti la utk receiver adapter.

ok atau tidak, terpulang pada struktur kawasan dan bangunan.
kalu dlm 1 rumah ada banyak dinding, kadang2 signal kuat tapi asyik drop aje. sakit ati pulak.

skrg ni, kaedah mana yg ko nak guna... ?
1- nk guna antena kuasa tinggi supaya buleh terima signal dari rumah kawan.
***beli komersil antenna 8dbi atau lebih tinggi. atau buat antenna sndiri.

2- belikan antena kuasa tinggi utk letak kat rumah kawan so signal tu sampai ke rumah.
***beli antena dan pasang pada router wireless. kena cek samada router tu mampu supply power yg cukup pd antena tu.

3- beli 2 antena kuasa tinggi. satu kat rumah kawan, 1 kat rumah sndiri. dua2 kuasa tinggi, ada can la...
***kat rumah kawan, refer no.2 **** kat rumah sndiri refer no.1

bzzts,
secara amnya kalau opt nak guna commercial product, aku akan guna opt 1 la

alat yg seswai utk outdoor maybe something look like this
http://cgi.ebay.com/SuperPass-2- ... idZp1742.m153.l1262

cable maybe kat sini ade
http://stores.ebay.com/Wireless- ... 60050QQftidZ2QQtZkm

or maybe cable boleh DIY atau beli siap pasal dia pakai N-female connector, bnc ke nama dia??
so aku kena beli N-male and then connect dengan wireless router kat umah aku guna RP SMA connector...

tapi umah member aku tu kalau dia pakai normal Dlink router leh dapat ke..aku just suruh dia pasang tinggi sikit kat tingkap palign tinggi.. rumah dia ade tingkap atas air well tuh.. kire paling tinggi la...
ko rasa possible ke tanpa member aku kena keluarkan kos lagi....

secara kasar, tengok pic ni

opt kedua maybe pakai cantenna je...sebab tu kalau nko gi pasar pudu nanti aku nak join..
cantenna ni selamat ke ... kalau ada lightning safe ke?

lagi satu

kalau nak DIY, instead of pakai tin. leh guna disc ke??
member aku ade lebihan disc astro nih...

bzzts · Post time 15-2-2008 03:33 PM

aaa... pakai dish tu mmg secara toerinya boleh, malah dah dibuktikan.
dlm link yg aku kasi tu pun siap ada graf signal, gain bertambah bila guna dish.

rujuk pada gambar rumah tu, aku ingatkan ko duduk taman perumahan. blok flat rupanya.
kalu flat, dia kene letak router atau atleast, antena tu kat bilik paling blakang atau kat luar tingkap.
tapi risau pulak takut kena lightning.
aku rasa, baik ko cuba dulu guna usb adapter wifi, ko modify antena tu tambah dbi.
guna wayar tembaga saja dah cukup untuk tambah dbi "gain" dia. cara ni le paling murah.
lagipun kalu dah ada usb wifi ni, antena tu buleh point ke direction yg kita nak. kalu tambah wayar, buleh letak antena kat luar tingkap.

ntah la DG, aku tk paham sgt bajet cemana yg ko sanggup.
sbb kalu cecah rm400, antena saja ; 12dbi pun harga RM289, router yg leh support antena tu pulak, paling cikai pun rm200 lebih.

kalu ko sanggup, mungkin buleh cari bende ni kat lelong : http://www.hardwarezone.com/news/view.php?id=4778&cid=8
dan pasang kat rumah kawan ko tu. harap2 signal leh sampai ke rumah.
bende ni bukan router, tapi cuma antena saja. diluangi : antena saja.

ini link lelong (RM300) : http://www.lelong.com.my/Auc/List/2008-02DStd11226784.htm
kalu buat cantena, sama je power gain 12dbi jugak, mungkin boleh dpt lebih... :re:

tapi kalu beli booster prolink ni, senang kerja.

Antenna Comparison Testing
(first published February 2003)

This page details the testing method and results when testing some downpipe waveguides, a collinear, some biquads, a cantenna, and a modified Conifer dish.

router komersil + modify http://www.it46.se/ref/IDRC_wifi_ifrane

Deployment of a 7km Point-to-Point Wireless Link

Ifrane, Morocco 2006

Problem Statement: Two administrative buildings (Atlas and Agdel) in the city of Fez needs to get inter-connected. The connection should allow the establishment of an Intranet to share e-government services.

Conditions: The two buildings are separated 1.5 kms but there is not Line of Sight (LOS) due to high buildings.

Action: During the North African Training Workshop in Wireless Community Networks, [Ifrane, Morocco] we planned and deployed a radio link that will allow the connection of the two builds. In order to get the two buildings connected it was needed to study the possibility of relying the radio signal in a mountain 7 kms away. As a result of using a high remote relay we wanted to explore the possibility of adding more sites to the wireless hub in the future.

cantena beli (cantenna.com)http://www.philblog.com/mt-archive/2005/05/cantenna.html

Cantenna

Some friends moved into our neighborhood a few weeks ago. They live three houses down the street from us. I thought it would be a cool project to extend our wireless network to their house, and after talking it over, we decided to try it.

7 km??? Wah... nak kena buat gak ni.... Dah kira boleh jadi homemade Malaysian NSA nanti...

DewaGanaZ · Post time 15-2-2008 04:52 PM

bzzts,

aku duduk rumah teres la...bila masa plak nampak cam flat drawing tuh..hehehe

aku ingat nak try guna cantenna tu dulu la..
sebab kalau mahal sangat baik aku subscribe je streamyx...

aku tengah baca link yg nko kasi tuh

cantenna ni selamat ke letak outdoor
kilat??

bzzts · Post time 15-2-2008 05:17 PM

soal tu, aku kurang pasti, tapi connector N-type ada yg siap dgn surge protector. mahal sikit.
camni hah... http://www.macwireless.com/html/ ... surge_protector.php

kalu yg biasa (takde surge protector), dia siap dgn cable 12inci je. mungkin patut cari kabel panjang sikit kot.

p/s: betol la, kalo mahal, baik apply streamyx sndiri.
