How to Create a Hotspot

Hotspots or places that provide Internet access services using wireless. If you want to open a Cafe business, or restaurant, for those interested and come to your home, you can make free Internet service for those who visit. This is because a number of devices that have been equipped with wireless technology, so the trend is the use of a higher.

How to Create a Hotspot
Unfortunately, not everyone understands how to build Wi-Fi infrastructure. Lack of information and perhaps a somewhat expensive price makes many business owners are reluctant to build a hotspot. In fact, there is great potential to add hotspots interest and also to increase revenues from the place itself.

This article will discuss important things you need to know to provide the hotspot service. This is discussed is relatively simple that can be followed by beginners though (as long as it already has the basics of network). At the end of the article, we discuss a tool that is practical enough to be used to create a hotspot.


Equipment Needed to Make a Hotspot:

1. Access Point.
How to Create a Hotspot

Function Access Point as a hub / switch on the local network, which acts to connect the local network with a wireless network / wireless the client / your neighbors, this is an access point internet connection from where you are emitted or transmitted via radio waves, the size also affects the signal strength coverage area will be achieved, the higher the signal strength (size in units of dBm or mW) to expand its reach.

2. Omni Antenna
How to Create a Hotspot
To expand the coverage area until a few Kilometers, you need an external omni antenna, even when you buy an access point equipped with omni antenna, but not enough because only a magnitude of about 3-5dB, to expand the coverage area, you'll need an external omni antenna, flat - average 15db power. Omni antenna has a radiation beam or 360 degrees, so the match can reach the client from any direction.

3. Box Access Point
How to Create a Hotspot
To protect your access point, need a box-shaped protective device, can be made of plastic or metal plate, the average box is equipped with a safety lock, and this box should be placed immediately below the antenna.

4. Pigtail
How to Create a Hotspot
Jumperl Pigtail wires or cables needed to connect between the omni antenna to the access point, the maximum length of notice required only 1 meter, if an extension you will experience signal degradation (dB loss) at both ends of the cables have connectors that plug type connector according to the inherent your access point.

5. POE (Power Over Ethernet)
How to Create a Hotspot
That the power cable has not been raised to "turn on" access point then you need a tool "POE" This tool serves to mengalirankan electricity via an ethernet cable or UTP / STP, with this tool you will not need to bother buying another power cord to the top of the tower , more practical and economical.

6. Cable UTP / STP
How to Create a Hotspot
Cables UTP / STP is needed to connect an access point with a network cable at your local LAN, so the computer can be connected to the Gateway / Router or Hub / Switch, select cable UTP / STP good quality to improve the quality of electricity through the POE. stpot

7. Anti-lightning (Lightning Arrester)
As a safety from lightning then you need a tool that serves to channel the electrical overload when lightning struck the cable earthing (grounding), this component is installed on jumper cables between devices and access points with external antennas. Grounding for lightning rods are generally planted with copper to a depth of several meters to reach the water.

8. Tower
How to Create a Hotspot
To get the maximum coverage area of ​​coverage, you need to raise external omni antenna to a high place for the WLAN client you can catch your radio signals properly.

Good luck ... :)

Utilizing WOS Portable as Portable Server

Nowadays there are many practical applications containing the installation package of Apache, PHP and MySQL like PHPTriad, WAMP5, XAMPP, AppServ, Wosportable and so forth. Wosportable one of the many installation packages in a bundle. In contrast to applications such as PHPTriad, WAMP5 and XAMPP, Wosportable an installation package that is more practical in the installation and is portable.

Be portable here means we can carry and store wosportable applications into the flash media and we can contiue the work of web programming that abandoned the office and continued home or on a different computer. here lies the advantage of wosportable, we can bring Apache, PHP and MySQL into the flash media or other stotage media. with this wosportable deserves the title as a portable server

Wosportable This package contains: Apache2 (Version 2.2.3), MySQL5_SE (Version 5.0.24) and PHP5_SE (Version 5.1.6) and can be downloaded on site with the following url address:
http://www.chsoftware.net/

Instalattion Wosportable
Once we download Wosportable will get the file is a wosportable.zip, we first extract the zip file.

Then we double-click on the file wos.exe

After a few seconds then comes the installation language choice, here are two choices of languages ​​namely English and German.

For the moment we choose English (Home) and clicked the OK button

This section is information onabout the terms of use and problems wosportable license . We have to give a mark on the box "I understand and accept this conditions ...." And click OK.

The next stage we menginstallasi package contained in this wosportable include:
Apache2 (Version 2.2.3)
MySQL5_SE (Version 5.0.24)
PHP5_SE (Version 5.1.6)
And then click the install button.

It would appear the information "Do you Want To install all packages now? we select OK. After that we will get the message straight.

This is information that the process intallasi Apache2, MySQL5_SE and PHP5_SE having successfully implemented. it will show a display monitor wosportable status.

Here is given information on the status of the Apache and MySQL in the road / running. In order not to disturb us can do to minimize this menu. And also can shut down and restart the application path.

In the next stage whether we can open the Mozilla Firefox browser, IE or another. And typed localhost will appear as follows:

Localhost shown they appear related information on Wosportable. In the testbed included a package of information that we have diinfokan installalkan and also our server's document root location. So we put on the document root web application files we. Need iperhatikan if we menginstallasi installation packages such as TYPO3, Joomla, WordPress and others in the document root, the administration login is to be the "admin" with password is "password".

enjoy using WOS Portable, we can make the webserver where we are, just copy all the folders and taken anywhere enggunakan usb stick, flash card or hard drive. And run the webserver will start wos.exe the road.

What is FoxServ?

For those of you who want to learn and interested in web programming may currently be confused with the number of web programming that offers a variety of features and ease of existing facilities. Quite a lot of web programming available today such as ASP (Active Server Pages), PHP (Hypertext Preprocessor), Perl / CGI (Common Gateway Interface), JSP (JavaServer Pages), CFM (Coldfusion), and so forth. Of the many web programming above, maybe PHP is currently being widely used. The factors that make PHP more widely used by web developers is:
  1. PHP are free alias does not pay.
  2. Its programming language easy to learn and is equipped with a function-function built in a rather large and easy for users.
  3. Supporting PHP, such as: Apache Webserver, MySQL database are free. So that will reduce costs incurred. This is especially affecting cheap hosting prices for servers that support PHP.
  4. Community of PHP users very much. So that would make it easier for us if you have trouble while to develop applications.
From the above factors will be many also support PHP applications that simplify the user, especially for people new to using PHP as its web programming language. To start using PHP we need to install a web server in our computer that can be obtained at http://www.apache.org, then install MySQL as a database server in our computer that can be downloaded at http://www.mysql.com, and the last that we have to install PHP on your computer by downloading it first on http://www.php.net The steps above must be very troublesome for the users of PHP are still common. Moreover, if we do not understand what kind of work a web server? and database server work it like how?.

Well, to reduce these difficulties, many in-develop the application bundle that is easier for users of PHP to run PHP on our computers. The application bundle is a fairly widely known today is Foxserv.

Apa itu FoxServ ?
Foxserv is a package installer for Windows systems that have applications in PHP, MySQL, and Apache. For version 3.0 has been supports PHP as a module, PEAR, and Zend
Optimizer.

Some applications are similar to existing FoxServ advance of PHPTriad.Namun unfortunately, PHPTriad until now been discontinued development and J Wynia PHPTriad-developer more interested in creating a "paid version" of his, named Sokkit
(http://www.sokkit.net).

Then there is also use installer for Windows which contains a bundle of PHP, MySQL, Apache made ​​friends KIOSS (Community OpenSource Indonesia) is given the name DongKRAK (http://www.kioss.com/kiossproyek.php?nama=aDongKRAK) and DingKLIK (http://www.kioss.com/kioss/proyek.php?nama=aDingKLIK) - minimalist webserver that supports PHP.

Know the Universal Serial Bus (USB)

USB is a standard port on the computer now, every computer that we buy today are always equipped at least one or more USB connectors. USB connectors can be ditancapi variety of devices ranging from mice to printers to easily and quickly. The operating system is also very supportive of the presence of USB, version of windows xp start up even already have the installer of USB devices in one package which include the windows program.

Compared to connect the device to another port type found in computers, the use of USB ports is very, very easy. A decade ago before available USB port on your computer. connecting a device to a computer can make the head spin. These problems include:
  • The printer must be connected to the parallel port, whereas most computers produced at that time even until now only comes with one parallel port only. Zip drives that require high speed connections also use the parallel port to connect to a computer. Speed ​​is needed is a high-speed data transfer, while the parallel port can not accommodate such high speeds, so we must be prepared for long wait only for a small copying data.
  • Modem, several types of printers, and digital cameras use a serial port to be connected to a computer, but most computers produced at that time only have a maximum of two serial ports. Just info serial port known to be very slow in the process of data transfer, because of data transferred serially bit by bit.
  • Devices that require a faster connection should be fitted with a separate card, which of course this requires a separate space if you want to be installed on the computer card slot. lucky if there was still some slots in our computer
The purpose of the creation of USB is to end the problem. Universal Serial Bus (USB) provides a single, standard and easy to connect the device to a computer up to 127 devices in a single USB port.

Some examples of devices that have been made ​​in the version of USB include:
  • Printer
  • Scanners
  • Mouse
  • Joystick
  • Digital Cameras
  • Webcams
  • Modem
  • Load speakers
  • Phone
  • Video phone
  • etc.
CABLE AND USB ​​CONNECTORS
Connect USB devices to a computer is easy. You just need to find a USB port on the back of your computer, then plug the USB connector into the USB port, and complete.

If you plug your device is a new device that has not been previously installed on your computer, your computer's operating system automatically recognizes it will try to auto detect. If the device driver is already installed on your computer then you can immediately use these devices. USB devices can be connected-off whenever required. Easy is not it?

Many types of USB device comes with its own USB connector cable. There are 2 types of USB connectors on the market ie the USB connector type A and type B. Using a standard USB connector type A and B to prevent consumer confusion. Use socket connector type A to USB type A and type B connector to the USB socket type B.

USB HUB
Most computers are currently only has at most 4 USB ports. What if you need more than 4 USB ports for your devices? Of course you can use a USB hub. When even this already widely available USB hub on the market ranging from tens of thousands of dollars you can get it. USB standard capable of supporting up to 127 devices on one port, one of which is a USB hub.

Generally has a 4 port USB hub, in some other types can be more than that. Plug in a USB hub to the USB port on your computer, then plug your USB devices to the hub. By connecting the hub-hub to each other you can provide up to tens of USB ports on your computer.

USB standard is able to provide supply voltage to the device that is connected to that port. Of course, devices requiring high power such as printers and scanners should have its own power supply, but devices that only require low power such as mice and digital cameras can be obtained directly from the USB power supply. 500mA USB power supply voltage reaches 5 V.

PROCESS THAT HAPPENED in the USB
When the host (computer) dole USB device, the host record devices connected to the USB bus and set the memory address for each device. The process is called enumeration. USB devices are also directly initialized by the host when connected to the USB bus. Hosts are also trying to find and choose the type of data transfer what is appropriate for the device. For example:
  • Interrupt - for devices that only require a small data transfer such as mouse and keyboard
  • Bulk - for devices that require large data transfers such as: printers
  • isochronous - for devices that require two-way data transfer, and require high resolution such as: speakers and webcam
Hosts can also send commands and record the necessary parameters using the control packet.

Once the device is recorded by the host, the host and then set the total bandwidth required by the devices that use isochronous and interrupt modes. The device with the data transfer mode can use up to 90 percent of the total 480 Mbps USB ports provided. After 90 percent of the bandwidth is used, the host will be denied access to the isochronous and interrupt the other. Control packet and packets for bulk data transfer type and then use the remaining total bandwidth (at least 10 per cent).

Universal Serial Bus (USB) divides the available bandwidth in the form of frames, the host and control frames. Frames contain 1,500 bytes, which is formed every millisecond. In the frame, the device with isochronous data transfer mode and the interrupt get its own bandwidth allocation according to bandwidth requirements of these devices.

USB CHARACTERISTICS
USB has the following characteristics:
  • USB can be connected to 127 devices, either connected directly or through a hub.
  • With a single USB cable to connect USB devices as far as 5 meters from the computer. With a USB hub device to connect as far as 30 meters, using only a hub 6 cable only.
  • With USB 2.0 data transfer speeds can reach 480 Mbps (Megabits per second).
  • The USB cable has two wires for the +5 V power and ground and a pair of wires as the data cable.
  • The USB cable that is able to have power supply voltages up to 500 mA at 5 V.
  • Devices such as a mouse can instantly get the power supply directly from USB. The printer requires a separate power supply so it does not require a power supply from the computer.
  • USB devices can be connected-disconnected from the computer whenever needed with ease.
USB 2.0 TYPE
USB 2.0 standard was released in the market since April 2000 which is the upgraded version of USB series 1.1. USB 2.0 (High-speed USB) provides additional bandwidth for multimedia and storage applications that have a data transfer speed 40 times faster than USB version 1.1. USB 2.0 also uses the same connectors and cables as its predecessor version so that the devices used to take advantage of previous versions can also be used in USB 2.0.

USB 2.0 Supports three speed modes (1.5, 12 and 480 Mbps), USB 2.0 is capable of supporting low berbandwith devices such as keyboards and mouse devices as well as high berbandwith like high-resolution web cam, scanner, printer and high berkapasitias memory system. USB 2.0 allows users to runa variety of USB devices at one time simultaneously ,without having the slightest disturbance .
