Wireless System

Wireless systems have increasingly become the inseparable ingredients of our lives in the last century because of their instant installation capabilities besides obviously cutting mammoth amounts of capital and time that was otherwise being wasted in erection and installation & commissioning. Nevertheless how big and expanded is the wireless systems industry? And how much they touch our lives? And if I am not stretching things too far, are we being controlled by wireless systems? Well, let's take a critical look at these issues which concerns us all.

Wireless Systems and Communication
Ever since Graham Bell and Marconi invented telephone and radio respectively, life has never been the same. Although they didn't revolutionalized things instantaneously they sure caused a ruffle thus signaling what was on the way. Today, without wireless systems communications would grind to a halt. Satellites become dud flying objects of little use if we don't "connect" through wireless for billions of gigabytes of data transfer every hour.

Consumer Wireless Equipments
At the bottom, we have wireless toys which are the rage with children. However the most common wireless system everyone is familiar is cell phone without which most of us can conduct our lives the way we need to. Cell phones have rapidly expanded to exit the wired phones in a matter of a few years. Even the basic phones are going wireless with the arrival of CDMA technology. The 3G cell phones can transmit up to 2MBPS of data.

Mobile phones reached their zenith of glory when Motorola introduced satellite phones (Irridium) which didn't even require wireless network but worked with satellites directly.

Connectivity is just notional; look at what broadband has done to wireless systems. Internet no more needs "wired connectivity" as there is wireless broadband service. IPOD has made world collapse into our pockets. What we imagined till the other year, the wireless systems made useful wireless microphones, was turned upside down by one small pocket gadget called IPOD.

Wireless Gadgets

If we are able to watch news cruising at 50,000 at great speeds, you could imagine what "the void" (wireless) can do. Let's take a look at some cute gadgets from the current rage.

1. Push to talk phones: Talk, browse internet, watch TV and connect to all your friends by one button push.

2. Pocket PC and wireless LAN for laptops: Pocket PCs double up as cell phones. Laptops connect to LAN with a wireless LAN card.

3. Toys, game controls etc.

4. Home theater, music systems, network booster and headphones etc.

An Easy Way to Build a Home Network

If you have more than one computer at home, you are probably better off connecting them or networking them together to use the same resources and receive the same Internet connection.  A home network is very easy to build.  Here are some tips.

There are two main types of home networks, wired and wireless.  While wired home networks are popular, but they require you to run wires from one computer to another.  You might have to drill holes in a wall or run wire under the carpet. 

If you don't want cords running all over the place, you can easily get rid of them with a wireless home network.  Wireless home networks are extremely simple to set up.  You only need a wireless router and a wireless networking card for each additional computer, you would like to hook up.  Most wireless networks can send and receive data lightning fast at megabytes per second. 

Wireless networks are extremely inexpensive, you can hook up a few computers for less than $200.  The great part of wireless networks is that all computers on the wireless network can use the same Internet or other resources such as a scanning machine and printer.  So if you are looking for a great way to share data and resources among your home computer, choose to build a home network.

Introduction of a router.

Router is a computer device that receives or forwards data packets to and from the Internet towards a destination in the process called routing. Router is the essential component of the computer networking that enables any sent data to arrive at the right destination.

As an illustration, imagine that the Internet is the world and one computer is one household. Other computers connected through the Internet are households around the world. Say one household will send a letter to another household in any part of the world. The letter has an address right and that address would determine the destination of the letter. However, without one reading the address, the letter would not arrive to the right receiver. The letter also would not be able to reach the intended receiver if there is not medium. This medium would be the courier. And the courier of the computer data is the router.

A router (broadband router) is also a device that enables two or more computer to receive data packets from the Internet under one IP address at the same time.

Remember that to be able to connect to the Internet, a computer must have an IP address unique from the rest of the computers. Therefore, every computer connected to the Internet has it own IP address. It is like having a fingerprint or ID as an access pass to be able to enter the web. With the presence of the router, this "fingerprint" or "ID" could be shared by two or more computer at the same time.

In simplest form, a router makes two or more computer use the Internet at the same with one access pass.

One more thing: a computer with cable modem could also be considered as a router. In this, the computer would do the process of routing like normal routers do. Other computers are then connected to the computer with Internet connection that would give it with the Internet connection. The computer with cable modem has the direct contact with the Internet and the ones connected to it are sharing the connection.

Why would anyone need a router?

For households with two or more computers who would want to have Internet connection to every computer they have, taking subscription for each would be too much. The solution is to buy a router that would enable every computer in the house to have an Internet connection. In the definition above, the broadband router would act as a hub to the existing Internet connection.

If the router is comparable to a hub, would it affect the Internet speed?

It should be considered that once a single Internet connection is divided, the connection speed is affected. However there are some broadband routers that would bring minimal slowdown to the Internet speed and the effect might not even be big.

Internet speed would also depend on the type of application used in a router. While some would inflict little effect on the speed like online games, others would terribly slowdown your connection and even hinder you to use the Internet at all.

Usually, offices use a more sophisticated router to redirect Internet connections to the large number of computers. These routers would give better data packeting compared to a typical router used at home that result to faster Internet speed.
