Basics Of A Wireless Router

Diposting oleh YohanesJati , Label: , Sabtu, 12 Maret 2011 07.05

Wondering how a wireless router works? "Based on radio technology, internal wireless routers allow you to connect to the network and talk to network devices without connecting a cable..
What does a Wireless Router do for a Computer Network?
A wireless router acts as a wired router; you can assign IP addresses and network applications, and Internet connections. However, wireless routers have an additional element: to transmit a wireless signal, so you can connect to a network without having to connect your computer to anything. Wireless routers are excellent choices if you have a laptop or want to connect a game console to the Internet without having to fill your home with wires. Some routers and wireless service provide Internet modems packages to create a wireless Internet router, which functions as a modem and wireless router.

Additional Components needed for a Computer Network to Function.
A wireless router is only one element needed in a wireless network, is useless without the wireless components to connect to the network. For example, if you have a wireless router, but your computer only has a wired network card, wireless router do not do much good. You need wireless network cards to allow the components to receive and use a wireless network signal. Some devices, like game consoles, and some computers are equipped with wireless receivers built in. If you do not have a built-in wireless modem, you can use a wireless USB external adapter or network card to access a wireless network.

Using Wired Connections and Wireless at the same time.
Most wireless routers have four slots for wired Ethernet connections. It is the perfect option if you want to configure your wireless router close to a desktop PC that does not have a wireless card, you can connect your desktop computer using a cable connection, and broadcast the signal wirelessly to your wireless laptop or other units. Wired connections are also very convenient for network devices such as sharing printers and external hard drives.

Standards Protocols may Vary depending on your Network
One of the hardest things for new users is to decipher the various protocols and wireless technologies. The three most common wireless router is 802.11b, 802.11g and 802.11n. 802.11g is by far the most common network protocol and widely used wireless, but 802.11n is becoming more popular because it offers higher connection speeds and better wireless range.

Unfortunately, 802.11n is not finalized yet, which means it can still change before the final specifications are determined. 802.11n devices are more expensive than their counterparts 802.11g, and you should select products that let you update the firmware you choose an 802.11n network device, so you can install the necessary updates.

Security Features Enabled is a Must
Wireless networks operate using radio signals, and it is possible for people to intercept these signals to access your network and steal your data. All wireless routers offer integrated encryption protocols and security. When you configure a wireless router, make sure to select the protocol of the most advanced security that your network and network devices can support. You must match the security protocol for each device you'll need to connect to the network.

Internet Hotspot Systems - How to Create a Public Internet WiFi System

Diposting oleh YohanesJati , Label: , , Jumat, 18 Februari 2011 08.26

Growing Internet WiFi Market
Public Internet WiFi or Hotspots are a very common sight that we can usually find in many public areas or places that require customers to use the Internet. More and more people and places around the world have access to the Internet. It is obvious that the Internet and access to the internet will keep on growing and will continue to be an important part in our everyday lives.

Steps to Setup a Hotspot
There are several steps to consider when creating an Internet WiFi or Hotspot. I will explain simple steps to create a public hotspot.
First and foremost is to determine your location. If you are intending to create a public hotspot you probably already have a place in mind. Your place of choice maybe a hotel, cafe, or any other public place the important thing is it is a place where people need Internet access.
Secondly is the Internet connection itself. You need to have an Internet connection in order to share or sell it to your customers. Find a local ISP for Internet connection deals and coverage.
Third is the hardware to share the Internet, typically you need a modem (from your ISP or your own) for the Internet connection. Also you would need a wireless router to share your Internet connection, there are many types of hardware with different capabilities to consider when choosing a router. Find the one that is most suitable for your needs.

Hotspot Types
After you have all the physical requirements to create a public Internet WiFi, the next step is that you need to decide if you want to charge for your hotspot or make it free. Typically places that would charge for Internet WiFi usage are hotels, camping grounds, harbors and business conferences. Places that often offer free Internet WiFi are Cafés, restaurants, waiting rooms, and other public areas.
There are also two types of hotspots that you can create. The first one is a non-manage Hotspot system that you can create straight away using your wireless router. The second one is a managed hotspot system, with this system you have to connect your wireless router to a hotspot service that allows you to manage your hotspot.

Non-managed Hotspot
If you are going to create a Hotspot without a managed system you can setup your wireless router with WPA2 security password for customers to join your WiFi network to access the Internet.
There are advantages and disadvantages of non-managed Hotspot. The advantages of non-managed WiFi systems are: Fast and Easy access also minimal maintenance and configuration. The Disadvantages of non-managed Hotspot systems are: less secure, simultaneous use (with one password many people can access the hotspot), vulnerable to bandwidth abusers.

Managed Hotspot
The other option is to have a managed Hotspot System. The requirements are the same as before but using a managed system you must do several more steps to modify your wireless router to configure the connection to the managed hotspot service. There are many managed Hotspot billing system providers out there, choose the one that best suites your need. Benefits of having a managed Internet WiFi system is that you can manage individual users, you can control how much time or bandwidth usage an individual user can consume. You can also have your own splash page before a user connects to promote your Hotspot, users can even pay using a credit card to access the Hotspot.

Those are some simple steps and examples of what you need to do to create an Internet WiFi system. Remember when creating your own public Internet access to consider your needs and requirements that is the right fit for your business.
