INTERNET SATELIT





Selama ini kita hanya melihat TV dari berbagai macam Stasiun TV swasta maupun TVRI. Juga TV luar negeri melalui melalui parabola yang menerima siaran TV luar negeri melalui Satelit. Teknologi ini memang hanya dapat menerima saja (downstream) karena DVB yang berformat digital dapat dilalui paket data internet yang berformat TCP/IP. Untuk upstream internetnya harus disediakan oleh ISP lokal baik melalui media wireless ataupun cable. Referensi untuk teknologi ini dapat diakses melalui: " DigitalVideo Broadcasting is harmonized digital TV that covers all media (satellite,cable and terrestrial).
 It supports Internet services at speed up to 6 Mbps and can be used on mobile devices http://www.3gnewsroom.com/ Peralatan yang dibutuhkan Untuk terselenggaranya Internet melalui teknologi ini, perangkat yang dibutuhkan adalah: 

1.   Antena Parabola TV Merupakan antenna parabola TV yang biasa kita lihat sehari hari pada rumah-rumah penduduk yang menggunakan parabola TV untuk melihat TV luar negeri dari satelit.
2.      DVB Card Merupakan card slot PCI yang dapat dipasang pada komputer pada slot PCI yang tersedia.
3.      LNB LNB biasanya terpasang pada ujung antenna parabola dan hal ini merupakan yang terpenting.

Merk Norsat merupakan standard industri dalam teknologi DVB ini. Norsat 8215 Digital, 15 Kelvin.Norsat products are engineered to be DVB-compliant. Silakan Anda lihat pada alamat www.norsat.com/industry/glossary.html Dari keterangan di atas akan dapat dikembangkan menjadi sebuah topologi internet yang lebih lengkap sebagai berikut: Dari gambar di atas menunjukkan bahwa akses internet downstream didapat melalui satelit dan DVB Router PC. Komputer yang dianjurkan hanyalah Pentium 2 dengan RAM minimal 128 MB. Anda juga bisa meng-install linux dan driver DVB-nya. Upstream akan di sediakan oleh ISP lokal, baik melalui teknologi wireless ataupun cable.Hal ini akan me nyebabkan efektifitas biaya karena pada umumnya kebutuhan downstream lebih besar daripada upstream.

Upstream digunakan hanya untuk request http, ftp, dan smtp email. Sedangkan downstream dibutuhkan oleh akses browsing, gambar, video dan lain sebagainya. Biasanya kebutuhan upstream berbanding downstream adalah 1:4. Artinya jika downstream 1 Mbps maka upstream dibutuhkan hanya sekitar 256 Kbps. Hal hal yang perlu diperhatikan Agar sistem ini dapat berjalan dengan baik maka hal yang perlu diperhatikan adalah pembukaan open filter IP pad a upstream provider. Artinya ISP lokal yang melayani upstream harus memperbolehkan IP (Internet Protocol) dari akses downstream melewati jaringan mereka (router mereka) . Sebagai contoh IP dari Hawaii Pasific Teleport http://www.hawaiiteleport.com/ 216.236.100.0/24 harus di open filter di router ISP lokal yang melayani upst ream sehingga sistem ini dapat berjalan dengan sebagaimana mestinya.









Automatic Backlink Creator




 ABC is the time saver we are all looking for

You have undoubtedly put a lot of work into creating your website. In order for that website to be effective, you need traffic. People have to find out about your site and you want high volume of traffic.  But how do you go about getting the word out there? Now there’s a way that won’t mean adding more work to what you’ve already done after getting your web site designed and up and running. Getting people to visit your website is as simple as ABC; Automatic Backlink Creator. The job of creating your own backlinks could not only put you to sleep, but the time you spend on that could very nicely be spent somewhere else. You did the hard stuff; now let ABC pick up the mundane and tedious stuff!

ABC: Features in a nutshell
Basically, what ABC will do for you once you’ve gotten your website up and running is let people know you’re out there. These are some basic properties of Automatic Backlink Creator:

·         What is the Automatic Backlink Creator? As someone is reading about a certain topic online, they may run across a word that is highlighted. As they pass their mouse over this word it trips the cursor into point mode. When someone clicks on that word, a hyperlink is created. ABC can make that hyperlink take whoever clicks that word directly to your site.
·         What will the hyperlink look like? Basically it will either be the title of your page, the title of your host (as in a blog) or the title of your site. This will appear in widgets along the side of a web page.
·         Can it be anything other than the title? Absolutely. It can be a key word. For instance; let’s say your website is about automobile parts. Your title is Dave’s Auto Parts. But if no one knows who Dave’s Auto Parts is, how would they find it? By using a key word, someone could be redirected to your website without even having to know the title of it. A key word such as autos, repairs or car parts could be used to create a hyperlink back to your website.

How does the Automatic Backlink Creator work?
ABC’s database stores all the information, keywords and titles of all the people/sites using this particular product. It (sometimes randomly) displays that information on all web pages associated with whatever category you have chosen to be associated with. It sounds a lot more confusing than it actually is but actually the work ABC does is actually much more direct. One thing is for sure, it will generate traffic!

Advantages of using the Automatic Backlink Creator
The time you save by having ABC create all these backlinks for you will be invaluable. The more backlinks you have going to your site, the more you can boost your ratings. And who doesn’t want that? Hundreds, possibly thousands of WordPress sites will be showing your hyperlinks without you having to do much at all. Your website is important to you, right? You can make the most of it by letting Automatic Backlink Creator make your website important to others as well.

ABC not only helps you launch your site, but users have reported being able to breathe new life into old sites that have all but stopped getting traffic. Your rankings can increase and you can hold onto them for longer periods of time due to the fact that ABC makes the building of your link’s following appear to be natural and organic. Links back to your site will appear all over the Internet progressively and the Automatic Backlink Creator gives certain randomness to it as well. So ABC works through a list of about 3000 indexing sites, pings your articles each time they are published to every site on its list which means more search engine spiders crawling all over your website.

Advantages of using Automatic Backlink Creator

Eliminate the most time consuming aspect of Internet Marketing

Creating your own web site can be fun but it’s hard work at the same time.  People who do so have undoubtedly thought it through and have decided that something meant enough to them that they wanted to actually create a web site about it.  Once all that work is done it would be nice to just sit back and watch your rankings grow.  Unfortunately, that’s not going to happen without taking a ridiculous amount of time to create backlinks, so that search engines, widgets, keywords and your title will hyperlink computer users back to your website.

How can the Automatic Backlink Creator save you time and money? 

·         Companies that provide backlinking services do so at a price anywhere from $1.00 to $500 per month. $1.00 being ridiculously and uncommonly low; $500 being the absolute highest that I have seen. Now that’s just for one link. Are you sure you want to pay such ala carte prices?
·         $37.00 a month with ABC buys you unlimited links and so much more.
·         Creating your own backlinks is not only time consuming but tedious, tiresome and (thanks to Automatic Backlink Creator) unnecessary. 
·         Your rankings will not only appear on your administrator’s page, thereby saving you the time of trying to figure out how to hunt down your ranking as the Automatic Backlink Creator will send an alert to your email address when your Google ranking has changed.
·         Writing articles takes time (I should know); Automatic Backlink Creator allows you to “republish” old articles as “new” simply by editing them. Talk about your time savers!
How does the Automatic Backlink Creator work? 
Everyone needs traffic to their website. Automatic Backlink Creator helps you create that traffic by tying in the title of your website, keywords, widgets and so on with others in its category (or sometimes randomly), thereby creating a hyperlink that will automatically take people to your website. They are also a guaranteed publisher of your articles (wish I had one of those). A lot of work goes into not only building but maintaining a website; with the assistance of Automatic Backlink Creator a lot of the work has been sort of hired out. You fill in the basics and they take care of the rest.

Advantages of the Automatic Backlink Creator
The advantage of saving money and time, having a guaranteed publisher for your articles, someone to do the work for you when it comes to creating backlinks to your website, having someone else track the ranking of not only your site but your key words as well… Come on. How many advantages can one little plug-in device offer? If that plug-in device is the Automatic Backlink Creator the answer is; plenty. The designer of ABC wanted to be sure that he went the distance and then share with others in his creation of this networking device. He’s excited about his product; you can tell when you listen to his video. Any time someone is as excited about their work as he is, it can’t help but translate into a great offer of a great service. Clearly, much time and money have been spent on research and development so that you can save your time and money.

Using ABC is like joining the ranks of a tightly woven community. ABC’s database stores all the communities’ residents’ information and helps them promote their website throughout the world via the Internet.

·         The more search engine spiders to your site, the more people will visit you and the higher your ranking will be.
·         In addition to pinging, your information will also be indexed up to 10 times a day.
·         Widgets will display between 5 to 10 links and change randomly every time the page refreshes, providing a constant stream of backlinks directing people to your website.

One amazing thing to note about ABC is that it allows you to submit Spintax form articles, furthermore, once the article is submitted, you can go in and edit it how you see fit.  Imagine how many submissions you could generate with just one, spintax article?

Not your average plugin!

The time you spend filling in the basic information needed for this process to run efficiently will be time well spent and will undeniably save you limitless hours, days, weeks, even months of work. I call that a serious advantage. And just in case you need yet another advantage, ABC’s creator is not one of those who takes the money and runs. He is easy to get a hold of and will return your emails expediently. Unfortunately, that can’t be said for a lot of services these days.

Automatic Backlink Creator V 2.0

Since the successful launch of the Automatic Backlink Creator, the team realizes that there are a few minor flaws in the first version and so they are releasing ABC version 2 that promises more features and higher reliability. Automatic Backlink Creator is an innovative way to produce and reproduce hundreds of backlinks into one’s site. The idea is beneficial to website owners as well as SEO experts.

Benefits of backlinking to your own site
Backlinks play a huge role in increasing your website’s online visibility. This will help increase your ranking in the search engine allowing more visitors to view your site. Backlinks can be produced manually or be purchased, either way you would be shedding off hundreds of dollars. If you prefer to do it yourself, you should ensure that you have more than enough available time to focus on creating the links, sending out emails from one webmaster to another for you to produce just about enough links to rank in the search engine. The sad part about it is that most of the times, you end up getting two way links, meaning that the website where you post your links will have the right to post on yours as well, although it is okay for you to create reciprocated links, the one way links will work better. Purchasing links is really expensive and could be out of your price range unless of course you own a large company that you don’t mind spending hundreds of dollar per month for a single link.

APA ITU dB, dBW, dBm, dBi?
dB (decibel) : Adalah satuan factor penguatan jika nilainya positif, dan
pelemahan/redaman/loss jika nilainya negatif
Jika input = 1 watt, output = 100 watt maka terjadi penguatan 100 kali
Jika input = 100 watt, output = 50 watt maka terjadi redaman/loss . daya
Jika dinyatakan dalam dB :

G = 10 log 100/1 = 20 dB
In Out
G = 10 log 50/100 = -3 dB == maka disebut redaman / loss 3 dB
dBW dan dBm adalah satuan level daya
dBW satuan level daya dengan referensi daya 1 watt
P(dBW) = 10 Log P(watt)/1 watt
dBm satuan level daya dengan referensi daya 1 mW = 10-3 watt
P (dBm) = 10 Log P(watt)/10-3 watt
Contoh :

1. 10 watt = ……. dbW
2. 100 watt = …… dBW
3. 1000 watt = ……. dBW

Jwb :
1. P (dBW) = 10 Log 10 watt/1 watt = 10 Log 10 = 10 dBW
2. P (dBW) = 10 Log 100 watt/1 watt = 10 Log 100 = 20 dBW
3. P (dBW) = 10 Log 1000 watt /1 watt = 10 Log 1000 = 30 dBW

1. P(dBm) = 10 Log 10/10-3 = 10 Log 104 = 10*4 = 40 dBm
2. P(dBm) = 10 Log 100/10-3 = 10 Log 105 = 10*5 = 50 dBm
3. P(dBm) = 10 Log 1000/10-3 = 10 Log 106 = 10*6 = 60 dBm

Kesimpulan :
10 Watt = 10 dBW = 40 dBm
100 Watt = 20 dBW = 50 dBm
1000 Watt = 30 dBW = 60 dBm

Terlihat bahwa dari dBw ke dBm terdapat selisih 30 dB sehingga dapat
dirumuskan :

P (dBm) = P (dBW) + 30 atau,
P (dBW) = P (dBm) - 30
Contoh :
15 dbW = …. dBm == 15 + 30 = 45 dBm
60 dBm = …. dBW = 60 – 30 = 39 dBW
dBi satuan gain antenna dengan referensi antena isotropis yang memiliki gain = 1 G (dBi) = 10 Log Ga/Gi = Gi = 1 = 10 log Ga

Contoh :
Antena Colinear memiliki Gain 7 kali dibanding antenna isotropis. Berapa dBi Gain antenna Colinear tsb?

G = 10 log 7 = 8.45 dBi

Contoh :
Antena Yagi memiliki gain 18 dBi
18 dB = Antilog 18/10 = 63.095 kali ~ 63 kali
Artinya gain antenna Yagi adalah 63 kali lebih besar dibandingkan antenna
Isotropis

Beberapa Contoh penggunaan satuan dB
Contoh 1 :
Sebuah Amplifier mempunyai gain = 20 dB, jika diberi input 10 dBm berapa
output amplifier tersebut?
Jawab :
Pout (dBm) = Pin(dBm) + G = 10 + 20 = 30 dBm
Contoh 2 :
Sebuah Amplifier dengan gain 30 dB, jika outputnya sebesar 45 dBm berapa
level inputnya?
Jawab :
Pout(dBm) = Pin (dBm) + G == Pin = Pout – G = 45 – 30 = 15 dBm
Contoh 3 :
Output amplifier sebesar 30 dBm akan dilewatkan kabel dengan redaman / loss 2
dB. Berapa level sinyal setelah melewati kabel?
Jawab :
Pout = Pin – L = 30 – 2 = 28 dBm
Contoh 4 :
Output RF amplifier sebesar 20 dBm akan diumpankan ke antenna parabolic
dengan Gain = 15 dB melalui kabel pigtail yang memiliki redaman / Loss 2 dB.
Berapa EIRP dari sinyal tsb.
Jawab :
EIRP = Po – L + Ga = 20 – 2 + 15 = 33 dBm
PARABOLIC ANTENA
JARAK TITIK FOCUS PARABOLIC
F = D^2/(16*d)
F : Jarak titik focus dari center parabolic dish
D : Diameter
d : kedalaman (depth)

Contoh :
Parabolic dish dg D = 70 cm, d = 20 cm maka jarak titik focus dari center dish :
F = D^2/(16*d) = 70^2 / (16*20) = 15.3 cm
Pada titik focus tsb dipasang ujung feeder. Untuk mendapatkan gain maksimum,
atur posisi feeder maju/mundur sampai didapatkan sinyal maksimum.
LEBAR BEAM / SUDUT PANCARAN (BEAMWIDTH) PARABOLIC
BW = ((3*10^8/f)*57.29)/D * √á¼£
BW : Beamwidth (deg)
f : frekuensi
d : diameter parabolic (m)
á¼£ : Effisiensi antenna (0.5) kalo bagus, krn wajan pake aja : 0.35 ~ 0.4
Contoh :
Antena parabolic dg diameter (d) : 70 cm
Frekuensi                      : 2.4 Ghz = 2.4*10^9 Hz
Effisiensi             : 0.4
BW : ?
Jwb :
BW = ((3*10^8/2.4*10^9)*57.29)/0.7*√ 0.4) *57.29 = 16.17 degrees
GAIN ANTENA PARABOLIC
G = 10 Log Eff + 20 Log f + 20 Log D + 20.4
G                : Gain antenna parabolic (dB)
Eff               : Efisiensi
f                  : frekuensi (GHz)
D                 : Diameter (m)
Contoh :
Diameter (d)  : 70 cm (=0.7m)
Frekuensi (f)  : 2.4 GHz
Effisiensi        : 0.4
G = 10 Log 0.4 + 20 Log 2.4 + 20 Log 0.7 + 20.4 = 20.926 dB ~ 21 dB
Misalnya dalam praktek pembuatan hasilnya meleset 3 db : 21 – 3 = 18 dB (masih lumayan)
REDAMAN RUANG BEBAS (FREE SPACE LOSS)
Lfs = 92.5 + 20 Log d + 20 Log f
Lfs : Redaman ruang bebas / Free Space Loss (dB)
   d : Jarak (km)
    f : Frekuensi (GHz)
Contoh :
Akan dibuat jaringan dari rumah ke kantor dg frekuensi 2.4 GHz dan jarak 10km. Berapa redaman ruang bebas untuk jarak tsb?
Jwb :
Lfs = 92.5 + 20 Log 10 + 20 Log 2.4 = 120 dB
LINK BUDGET
Perhitungan link radio untuk menentukan apakah RF power yg dipancarkan
station A memenuhi syarat minimum level yg diperlukan setelah diterima di
station B, shg kedua station dapat berkomunikasi
Contoh :
Tx Power Station A : 20 dBm, Sensitivitas Receive station B : -83 dBm. Maka
station A dan B dapat berkomunikasi jika TX Power yg dipancarkan station A
setelah melewati freespace loss sesampai di station B levelnya -83 dBm atau lebih besar
Misal :
Jika Rx Signal Level (RSL) di stasion B = - 70 dBm (>-83 dBm) maka A dan B
dapat berkomunikasi
Jika RSL di station B = - 90 dBm (<-83 dBm) maka A dan B tidak dapat
berkomunikasi
Jika diketahui parameter : Tx Power, Rx sensitivity, jarak kedua station, dan
frekuensi, maka :
· Redaman Ruang Bebas (Freespace Loss) dapat dihitung (berdasar jarak
dan frekuensi)
· Untuk membuat sinyal dari A sampai ke B tinggal menentukan Gain
antenna Tx (Gt) dan Gain Antena Rx (Gr).
Contoh :
Jarak rumah ke ISP = 10 km. Akan dibuat radio link dg frek 2.4 GHz
menggunakan sepasang WLAN dg Tx Power = 15 dBm, Rx Sensitivity = -83 dBm.
Antena parabolic yg digunakan di rumah Gt = 22 dB, antenna yg di ISP Gr = 19
dB. Loss / redaman) saluran transmisi dari WLAN ke Antena diabaikan.

Lfs = 92.5 + 20 Log d + 20 Log f
RSL = Ptx – Lst + Gtx – Lfs + Grx - Lsr
RSL >= Rx sensv
Station A Station B
Pertanyaan : Apakah A dan B dapat berkomunikasi?
Jwb             :
Lfs = 92.5 + 20 Log f + 20 Log d
= 92.5 + 20 Log 2.4 + 20 Log 10
= 120 dB
RSL = Tx + Gt – Lfs + Gr
= 15 + 22 – 120 + 19
= - 64 dBm
· Lihat RSL (-64 dBm) > Rx Sensitivity (-83 dBm)
·  RSL sebesar 19 dB lebih besar dari level minimum yg diperlukan shg A
   dan B dapat berkomunikasi dg rate maksimum.
·  Dalam praktek RSL 15 dB di atas Rx Sensitivity sudah cukup (disebut
   fading margin atau Sistem Operating Margin)

Jika jari-jari lingkaran penampang Circular Waveguide diketahui maka panjang gelombang terbesar (frekuensi paling rendah) yang dapat dilewatkan dapat dihitung dengan rumus berikut :
r = jari-jari (m)
Frekuensi terendah = 3x108 / λo = 3x108 / 3.4r
CONTOH :
Kaleng susu dengan diameter 98 mm. Berapa frekuensi terendah yang dapat dilewatkan melalui kaleng tersebut?
r
λ0 = 2 x Π x r
1.8414
= 3.4122 r = 3.4 r
Jawab :
r = D/2 = 98/2 = 46.5 mm = 0.0465 m
Frekuensi terendah = 3x108 / 3.4 x 0.0465 = 1897533206.83 = 1897.5 MHz
Jika kaleng susu di atas akan dibuat feeder untuk frekuensi 2437 MHz (Channel 6 Wifi) maka mountingnya adalah sebagai berikut :
Berapa λg/4 dan λ/4 ?
λ = 3 x 108 / 2437 x 106 = 123.1 mm
λ/4 = 123.1 / 4 = 30.775 mm ~ 30.5 mm
λ0 untuk kaleng diameter 98 mm adalah = 3.4 r = 3.4 x 46.5 = 158.1 mm
λg = λ
√1 – (λ/ λ0)2
(λ/ λ0)2 = (123.1 / 158.1)2 = 0.60625
1- (λ/ λ0)2 = 1- 0.60625 = 0.39375
√1 – (λ/ λ0)2 = √0.39375 = 0.6275
λg = 123.1 / 0.6275 = 196.1753 mm
λ g / 4 = 196.1753 / 4 = 49 mm
λ/4
λg/4

MODE OPERASI
MODE #1 : ACCESS POINT (POINT TO MULTIPOINT)
MODE #2 : CLIENT BRIDGE P2MP / AP CLIENT / WIRELESS ETHERNET
BRIDGE
MODE #3 : CLIENT BRIDGE P2P / AD HOC
· Perlu 2 (dua) IP Address (untuk WLAN dan LAN adapter)
· Menggunakan Power Supply External
· Dapat menggunakan kabel UTP yang panjang untuk keperluan outdoor
WLAN USB (USB WIFI ADAPTER)
· Kebanyakan berfungsi sbg client adapter
· Perlu 1 (satu) IP Address
· Power supply diambil dari port USB pada PC (tak perlu Power Supply
  tambahan)
· Dapat menggunakan USB Active Extension Cable untuk keperluan
  outdoor dengan panjang terbatas 4~5 segmen kabel (20 ~ 25 meter)
· Kabel USB Active Extension harganya lebih mahal dari kabel UTP dan
agak Sulit  dicari.

WLAN PCI CARD
· Kebanyakan berfungsi sbg Client
· Perlu 1(satu) IP Address
· Power WLAN dari slot PCI
· Jika antenanya akan ditaruh di luar gedung, perlu memperpanjang kabel
  coaxial ke antenna
· Kabel coaxial untuk frekuensi 2.4 GHz yang panjang selain mahal juga
  menimbulkan Loss / redaman sinyal RF

ANTENA 2.4 GHz

Beberapa Contoh Design Antena 2.4 GHz
Kebanyakan antenna homebrew wifi yg ada di internet : antenna yagi, antenna kaleng (tincan antenna), antenna biquad, antenna helix, antenna slotted waveguide. Komponen yg selalu ada dlm design antenna-antena tsb : N-type
Connector & pigtail
Konektor : N-type Male, N-type Female, RP TNC Male, RP TNC Female, Pigtail
1.   Antena Yagi Antena Colinear
2.   Antena Kaleng (Tin Can Antenna)
3.   Antena Biquad & Double Biquad
4.   Antena Waveguide Slot
5.   Antena Helix
6.   Antena Horn Antena Parabolic Grid
Dengan adanya N-type Connector dan Pigtail maka :
· Biaya beli konektor dan pigtail
· Perlu penyolderan
· Timbul Loss / redaman sinyal RF akibat sambungan yang tidak baik dan
  panjang kabel pigtail
· Timbul SWR jika saluran transmisi (pigtail) dengan antenna tidak match
  Design antenna yang tidak memakai pigtail
Kemudahan yang didapat :
· Tidak memerlukan N-type connector dan pigtail sehingga menghemat
   biaya
· Tidak memerlukan pekerjaan penyolderan
· Tidak ada Loss / redaman sinyal RF
· Tidak ada urusan lagi dengan SWR
Antena WajanBolic
Kenapa disebut WajanBolic?
· Wajan : penggorengan, alat dapur buat masak
· Bolic : parabolic
· WajanBolic : Antena parabolic yg dibuat dari wajan
Karena berasal dari wajan maka kesempurnaannya tidak sebanding dg antenna parabolic yg sesungguhnya.
Dalam workshop akan dibuat Antena WajanBolic dengan Wifi USB Adapter
dengan pertimbangan :
· Tidak perlu pekerjaan penyolderan kabel dan konektor
· Tidak ada pekerjaan modifikasi pada system RF sehingga tidak perlu
   khawatir dengan masalah SWR
· Tidak perlu bongkar casing PC dalam instalasinya seperti jika
  menggunakan Wifi PCI Adapter
· Tidak perlu power Supply external, karena power supply Wifi diambil
  dari port USB PC Desktop atau notebook sehingga memudahkan pada
  saat outdoor live test menggunakan notebook
· Operasional koneksi ke AP mudah
  Beberapa kekurangan antenna WajanBolic :
· Karena berupa solid dish maka pengaruh angin cukup besar sehingga
  memerlukan mounting ke tower yang cukup kuat
· Untuk keperluan outdoor diperlukan USB Active Extension Cable
  beberapa segmen sehingga untuk panjang kabel tertentu harga kabel
  menjadi lebih mahal dari Wifi USB
