Using Mobile Broadband With Your Netbook

Article By Dave Millard

Most laptops and netbooks now have a built in wireless card that allows them to connect to a broadband signal broadcast by a wireless router. This secure router might be located in your home or office, but if you are away from these sources and need to get online the alternatives are to either find a WiFi hotspot or use mobile broadband. A WiFi service can often be found in motorway (freeway) service centres or other public places but although they are free to use, they are not very secure so should be avoided when accessing anything confidential.
Mobile broadband
Mobile broadband is basically a mobile (cell) phone line registered to you which gets a 3G/HSPA signal from a mobile phone network. Security is usually very good and the service can be accessed via a netbook fitted with a USB "dongle" (or modem) - just plug the dongle into your computer and you can be online in minutes. A mobile broadband service like this is great when you are on the move, but can also act as a backup to your home or business broadband connection. For students or anyone without one main fixed address it is often ideal, particularly as "pay-as-you-go" versions are now widely available.
Shopping around for a Dongle
The term "broadband dongle" is commonly used to describe the device that acts as a mobile modem, but they are also called USB modems. As they operate on a mobile phone network they need a SIM card (just like a mobile phone), and the drivers for this should automatically install on your netbook when it is plugged in. Most networks' dongles can be used overseas, but be aware that the costs can be huge, particularly when used to download big files like movies. If you are away on holiday, check out the hotel's WiFi instead - it is probably a much better choice.
Download limits
When shopping around for the best service you may find that you get a better deal if you sign up to a broadband provider that bundles in a television or landline telephone service. Something to be aware of is that mobile broadband packages tend to have much lower download limits than landline-based services, and if you exceed these you can incur quite large charges.
Speed
Once you have compared mobile broadband providers, decide if you are likely to use the service in an area that doesn't have good 3G coverage. Inner-city areas will generally receive faster speeds and a better signal than those in a rural location, so before you sign up to a service it's worth checking their coverage map. Don't forget, the speeds advertised by mobile broadband providers will be sufficient to access modern internet facilities but rarely match up to home broadband so the service may seem slow by comparison.
Summary
Essentially, a mobile broadband service is a type of portable wireless broadband that is widely used with laptops, netbooks and mobile phones. Mobile broadband is proving hugely popular but there are very few independent resources for the consumer to find the best mobile broadband deal, as most providers are part of a large telecoms organization. There are a few suppliers, however, that will discuss your mobile broadband requirements and offer advice on the nest type of Internet access for your needs. Once you have it you will not want to be without it, especially when you are on the move - convenience and security for a low cost means great value.

How to Connect Your Netbook to a Wireless Network

Article By Dave Millard


One of the great benefits of a netbook or mini laptop is the ease with which they can be carried as they are so small and light. It makes sense to take full advantage of this by setting up a wireless network that eliminates the need for wires and allows you to connect to the Internet via broadband whenever the netbook is switched on, and to share the connection between more than one computer if you wish.

Types of broadband
There are two types of broadband service - ADSL, which uses the telephone lines, and Cable, which uses a cable network. Both require a piece of equipment called a "router" in order to work, and they are different for each service. Make sure you have the right type of router for your broadband service or it will not work.
Why go wireless?
If you use a wired router connection from an ADSL or cable modem you can only connect a single computer as there is only one network (Ethernet) port leading from the router to the computer. However, with a wireless router you can connect the Ethernet cable to the router which will than broadcast the wireless signal to as many computers as you want.
Types of Router
When you first register for broadband with an Internet Service Provider (ISP) you will be sent a router which you must install yourself so that you can connect a computer to it. Occasionally, if you have a cable service (like Virgin Media or NTL in the UK), an engineer will visit your home and fit a "cable modem" for you first. You will still have to connect the router to it yourself though.
How to Set Up a Network
To set-up a wired connection, all you have to do is follow a few simple steps; you attach a cable from the telephone socket (or cable modem) to the router and another cable from the router to the computer, power up, configure the router, set up security and you're done. Every ISP provides detailed instructions on how to set this up specifically for their service, so keep the instructions and follow them.
Each computer will need a wireless card (or adapter) to read this signal and connect to the Internet, but most modern laptops and all netbooks have this built in. If you set up a wireless network in your home or office, you can connect to the Internet, share printers and even files between any computers connected to the network - that way, any computer can send jobs to the printer.
To set up a wireless network you need the following components:

• a broadband internet connection (either ADSL or cable)
• depending on your ISP, a modem
• filters and/or signal splitter for an ADSL phone line
• a wireless router and two network cables
• a computer with a built in wireless networking card or
• If it's not built in, a wireless network adapter for each computer

Setting up your Wireless Broadband Internet
Once you have everything you need, set up the wireless network as follows:
Step 1
Plug the filter into the phone socket, then the cable from the filter into the ADSL modem
Step 2
Plug network Cable 1 into the ADSL modem
Step 3
Turn on the power into the modem
Step 4
Plug the other end of Cable 1 into the router
Important: If you don't have a modem, connect the filter (microfilter) to the phone socket then connect the telephone line from the filter directly into the back of your router.
Step 5
Turn the power to the router on
Step 6
Plug Cable 2 into the router
Step 7
Plug Cable 2 into the Ethernet port of the computer
Step 8
Turn on the computer and open a browser
Step 9
Type in the default IP address (192.168.1.1) to open the configuration panel
Step 10
Configure the router as follows:
default username is usually "admin"
default password is usually "admin"
enter the network key (SSID)
Step 11
Set security options
choose either WEP or WPA-PSK
choose the encryption type
When you finish configuring the router, unplug the Ethernet cable from the computer. You should now be able to locate available networks from the icon in the system tray in the bottom right-hand corner of your screen. Locate the network you have just set up and choose connect.

LCD Vs Plasma: Which Is Best for HDTV?

Article By George Dauberman

The whole "LCD vs Plasma" debate has been going on for years, but now might be a good time for us to take another look. With HDTV the new technology, and with all the new range of HDTVs on offer, you might be unsure of which route to go down. Here I am going to take a look at both sides, so that we can get a balanced understanding of the benefits of both. I'm going to start by outlining how LCD works, followed by the benefits of LCD. Then I'm going to discuss how plasma works, and highlight the benefits of plasma. This will then be rounded off with a conclusion where I summarize the main points, helping you to decide which type of TV would be best for you.

How LCD Screens Work

LCD stands for Liquid Crystal Display. Liquid crystals are not actually liquid, but they do behave more like a liquid than a solid, and this is how they got their name. They are kind of somewhere between a solid and liquid. They can remain in one place like a solid, but they can also move and change shape like a liquid.

To generate a picture, LCD screens use the same technology as used in polarizing sunglasses. At the back of the screen is a large bright light projecting forwards. In front of this light is a horizontal polarizing filter which blocks all light waves that aren't vibrating horizontally, meaning that only the horizontal light waves are able to pass through the filter.

The pixels of the screen are made up of lots of tiny liquid crystals. Behind each pixel is a transistor which controls the amount of electricity flowing through the liquid crystal. Each crystal is twisted, and in front of this is a vertical polarizing filter that only lets vertical light waves pass through. When electricity passes through the liquid crystal, it straightens out, blocking all light, but when this electrical current is turned off, the crystal twists and lets the light out vertically.

Benefits of LCD
Great for displaying static images.
Full color detail.
No flicker or screen burn-in.
Available in a wide range of sizes.
Longevity - LCD screens can last as long as 100,000 hours!
Very energy efficient.

Disadvantages of LCD
No as good as Plasma for fast scenes.
As the backlight ages, the white balance of the LCD screen can become inaccurate.

How Plasma Works

A plasma screen contains thousands of low pressure, sealed glass chambers filled with "plasma", which is a mixture of neon and xenon. Each of these chambers has behind it a set of colored phosphors: one green, one blue, and one red. The plasma chambers, when energized, give off an invisible UV light which hits the various colored phosphors, causing them to produce visible light.

Benefits of Plasma
Reacts well to a truly digital image source.
Great for fast moving action.
High contrast.
Available in larger sizes than LCD.
Better value for money, especially with larger models.

Disadvantages of Plasma
Prone to burn-in (not good for static images)
Brightness of screen gradually fades with time (although this happens extremely slowly, over many years).
Consumes more power than LCD.

LCD vs Plasma: Which Should You Choose?

So, which do you choose? LCD or Plasma? Well, the answer to that lies in what you will mostly be using it for. If you want a screen that is very big, and is great for displaying very smooth fast action scenes at extremely high contrast, then Plasma is the one for you. This is particularly true if you're into fast action movies or if you're an avid gamer.

However, if color, longevity and energy efficiency are more of a concern to you, and you don't go in so much for the games and the fast action, then LCD is right for you. This is particularly true if you're planning to use your TV for viewing any static images, for example if you wanted to plug in your digital camera and browse through your photos, or if you wanted to also use your TV for browsing the internet (as certain models of LCD do have internet TV functions).

So, what now? If you have decided on which type of TV to go for out of Plasma or LCD, but you're not quite sure which model to go for, then here are my recommendations:
For a great LCD TV, take a look at the [http://the-info-zone.info/samsung-ln46b630-46-inch-lcd-tv-dont-buy-without-reading-this-review/]Samsung LN46C630.

What is Home Wireless Networking?

Author: Wireless Advice

Home wireless networking is just what it sounds like -- a way of creating networks without any wires within your home! If this sounds exciting to you, then read on. With a home wireless network, you can create radio connections between computers that let them communicate and connect to the Internet without you having to go to all the trouble of connecting them with wires. The computers don't even need to have a clear path for the signal, as the wireless signal can go through walls and between floors easily.

Where Did It Come From?

The story of wireless networking is a rather strange one. It is basically an application of a technology called frequency hopping which was, believe it or not, invented by the actress Hedy Lamarr and a musician named George Antheil, back in the 1940s. Seriously, do a web search -- I promise I'm not pulling your leg here. They received a patent for their invention, which was intended to help in the war effort. Hedy was Jewish, but had been made to hide it and socialise with Hitler as a young woman -- she had to drug her husband and run away to London to escape her native Austria. The importance of what they'd done, however, wasn't recognised until many years later.The U.S. military adopted the technique in the '60s, using it during the Cuban Missile Crisis. Hedy never saw any money from it as the patent had expired (don't worry, she was a film star!), but she was given a Pioneer Award by the Electronic Frontier Foundation in 1997, three years before her death.

Wireless Network at Home

When most people talk about wireless networks, they are talking about wireless LANs (local area networks). A local area network doesn't mean that it covers your whole neighbourhood -- the 'local area' in question can be only one building, such as your house. So if you want wireless networking in your home, you want a home wireless LAN.Once people have wireless in their home, they always seem to act as if there's been an absolute miracle. After years of drilling holes in the walls and running wires all over the place, suddenly seeing them gone is really amazing.

Home Wireless Network Myths.

Home wireless networking is expensive. Well, home wireless networking used to be expensive when it was new, but now the prices have come way down thanks to competition and mass production. There are hundreds of manufacturers of wireless equipment, with something for every budget. Your costs will depend on how many computers you want to connect and how far apart they are, but a typical family should still be able to do it for less than $100 overall. If you're willing to leave one of the computers on whenever you're using the other one, you could do it for as little as $20! Best of all, once you've spend the money, there's nothing more to pay after that.Wireless networking your home is hard. Again, this myth is a holdover from the early days of wireless. It used to be very difficult, with you needing to fiddle endlessly with the configuration on each computer just to get the simplest things to work. Now, though, windows supports wireless out of the box, and setting it up is easier than ever. You can usually plug in what you've bought, put the CD in the computer and then sit back and watch it all work perfectly!A home wireless network is insecure. You might think it's dangerous to have all your personal data floating around in the air for anyone to read. Well, if you want, it's dead easy to enable encryption for your wireless signals. It's already difficult for outsiders to intercept wireless signals at all, and they certainly won't be able to decode them as well.

Not Just at Home

It was home users that were quickest to adopt wireless technology, willing to pay any amount to finally be free of needing to run wires all over their house. Since then, though, the technology has started to spread to offices, universities, and all sorts of other places.Chains of coffee shops and cafes have found that their customers will stay for hours if they offer wireless Internet access, and it's also becoming more common in hotels andairports. This means that once you set up a laptop for wireless, it becomes far more portable than it ever was before.

Important Tips in Buying a Wireless Router

Important Tips in Buying a Wireless Router

Author: David H. Urmann

With the popularity of the Internet and the introduction of wireless technology, there is a high demand in using a wireless router. May it be for your home network or for business; it is a practical solution to purchase a wireless router. A wireless router is more economical than having a wired network.

A wireless router is an electronic device used to connect multiple computers in a network. The wireless router is also capable of sharing one Internet connection to any device or computer connected in a network.

If you are planning to setup a home network, there are some important aspects you must consider before purchasing a wireless router for your project. Most of the wireless routers in the market today look the same but these routers have their own specifications different from each other.

Here are the important things you must look into when purchasing your wireless router.

The speed rating of a wireless router is important in order to achieve the best performance for your network. The speed rating of wireless routers are usually in Mbps or megabits per second. The early models of wireless routers comes with an 11 Mbps speed while the mid range models which are known as 802.11g routers has a speed rating of 54 Mbps. The Draft N routers which are the latest models are advertised with a speed of 300 Mbps. In this case, most buyers tend to choose those routers with the highest speed rating.

But this should not be the basis since in reality the actual speed you will achieve with these routers is actually lower than the maximum speed indicated in these devices. In addition, high speed wireless routers do not significantly boost up your Internet connection as you may be expecting. So why spend more money with those high speed routers if you won't gain the maximum speed they claim.

Some of the models or brands of wireless routers are very popular. It means most consumers are buying such brand. Maybe there is a point in judging the performance of these popular models based on the number of consumers buying these models. If you tend to go along with the popularity of these popular models of wireless routers, you may check with online retailers on the sales ranks of these models.

Most products come with a warranty package from the manufacturers. Make sure to read carefully the terms and conditions of the warranty package. Also check the how long they can provide the warranty. The best warranty you can get from a manufacturer means that they are more committed in providing support to their equipments and that their product is of higher qualities. Consider the warranty whenever purchasing your wireless router.

Mostly wireless routers installed at home are installed in an area which is visible. Though it is not so important in terms of functionality but the size and design of your wireless router can add up some attraction in your home. Wireless routers come in different sizes and designs. If you are going to purchase one, choose a good design and size suitable to the interior in your home so you could be proud to show off to your friends.

Brand matching between the network adapters you are using with the wireless router can sometimes help in achieving the best performance in your home network. Some manufacturers tend to provide optimization with their products.

You may find significant performance when using the same brand in your home network setup. Besides optimized performance you will surely have no problems in terms of compatibility. If you haven't purchase anything yet for your home network project, it is advisable to purchase all necessary equipments with one manufacturer.

One of the most basic things in purchasing a wireless router is your budget. With so many varieties of wireless routers in the market today, you can surely find an affordable one with features suitable for your home network. Look around the shops and you will more likely find a good buy for your budget.
