Obtaining and connecting to wireless Internet access is rather simple and can be easily accomplished by both the residential and business user.  The result is well worth the effort and will become the biggest advantage to using your laptop PC.

To set up a wireless connection, you must have a broadband Internet connection.  This service can be obtained from your local cable company at a monthly cost.  The service is provided to you through a high speed cable connection set up in your business or residence.

Once your broadband Internet connection is installed, you will need to purchase a wireless router and a wireless network adapter.  The wireless router acts as a base for your broadband Internet connection and converts the connection into wireless access.  The wireless network adapter is needed if you have an older computer that does not have wireless capability. The adapter will assist your computer in connecting with the router.  If you have a newer computer with built-in wireless capability, there is no need to purchase a wireless network adapter.

When connecting the wireless router you will need to disconnect the DSL (Digital Subscriber Line) modem that was installed with your broadband Internet connection.  Connect the router to your DSL modem by disconnecting the network cable from the back of your computer and connecting it to the Internet port located in the back of the router.

Reconnect the DSL modem and wait until it connects to the Internet before engaging the wireless router.  You will know when your router is functioning properly when the light is on signaling an Internet connection.

You will need to configure the wireless router through Internet Explorer.  This is easily accomplished by typing in the URL address and identification number of the router.  This information can be located in the instructions that are included with the purchase of the router.  You will need to read the instructions due to the fact that the configuration settings procedure will vary according to the brand of the wireless router you purchased.

If your computer has built-in wireless capability it should automatically locate the wireless connection.  If it is necessary to go with the network adapter, you will need to connect it to an available USB port on your computer.  For Windows XP and higher, it will automatically find the adapter and then walk you through the configuration.

For best results, the wireless router should be placed in a central location and away from metal objects that could potentially interfere with the wireless signal.  If the signal tends to be consistently weak you can always employ a wireless repeater to extend the range and strengthen the signal.

If you have cordless telephones in your business or residence, be sure to set your wireless router on a different channel for wireless Internet other than the channel used by your telephone.  If you omit this step, your Internet connection will pick up the telephone signal and constantly disconnect every time the telephone rings.

Wireless connectivity means greater mobility and flexibility when it comes to your computing experience and expansion of your computer’s capabilities thanks to high speed wireless.

Whether you are a business or residential Internet surfer, a wireless Internet connection or Wi-Fi can significantly improve your computing experience with lightning fast broadband speed as well as improved mobility.

With our rapidly growing technology oriented society of personal digital assistants, cell phones, and other mobile technology, the demand for wireless connections with increased broadband width has significantly increased over the last few years.

Wireless Internet connectivity has become more affordable and reliable thanks to the advances in bandwidth technology that provide data transfer up to two megabytes per second where the norm used to be one megabyte. Additionally, a wireless broadband connection is more reliable than a satellite connection because the signal does not have to travel as far for data transfer to commence.

A wireless Internet connection also provides a fast response when you download Web pages and facilitate email messages due to the improved bandwidth technology. Interactive applications such as videoconferencing, chat, gaming, multimedia programs, and social networking, are much easier to use and navigating your computer in general becomes much more efficient.

For the residential Internet surfer, wireless Internet connectivity means being able to access a high speed connection without having to install fiber or any associated extra lines. What’s more is that you can create a complete wireless Internet connection throughout your home that will allow you to access the Internet anywhere within a one-hundred foot range. This means you can sit out on your deck with your laptop if you wish or move about freely within your house without sacrificing Internet connectivity. With wireless Internet you are no longer limited to one room of the house or even one computer.

Wireless Internet connectivity also has a distinct advantage over a network because it is easier and more cost effective to set up without the necessary wires that are usually required for a conventional network configuration.

For the business user, wireless Internet connectivity means the sky is the limit with regard to mobility. Business people are no longer chained to a desk and can network with colleagues from anywhere, at any time, and in any place via email, instant messaging, and Web cam conferencing.

If you have recently purchased a new PC, you will find that most of them are equipped with wireless capability as a standard feature. This nifty feature will automatically find the nearest wireless access point and automatically connect to it, unlike the older methods of having to configure your computer to access a connection.

Wireless Internet connectivity also allows you to use your PC without the complications of devices that require connection with a cable. With a wireless connection, the devices are enabled with what is called Bluetooth capability and they will easily work with any wireless connection.

Wireless technology has also increased its advantages with new breakthrough devices such as wireless stereo speakers, headphones, computer peripherals, televisions, and microphones. Without a doubt, we are rapidly becoming a wireless society and in many ways the advantages are leading to a less stressful and easier way of life in both the personal and professional venues.

Advantages of wireless internet
Wireless internet has many advantages for both the business as well as residential users. Wireless internet provides excellent broadband speeds. Today speeds of over 2 Mbps for commercial use (megabytes per second) are attained using wireless internet.

Previously speeds of up to 1 Mbps were acceptable for wireless internet, but with service providers providing speeds of 8 Kbps and above to business and residential customers through cables (fiber optic), expectations through wireless internet too are running high. This could mean just one thing -speeds through wireless internet will sooner or later catch up with speeds offered through fiber optic cables.

Wireless internet is more reliable as compared to internet via cable or satellite. Initial costs to the service provider too are reduced as they do not have to lay out expensive cables or pay highly for satellite transmission. All that is required is the setting up of internet towers (very similar to mobile towers). The user will be connected to the internet as long as his laptop / device receives a signal from the nearest tower (again, very similar to using a mobile phone).

Comparisons between the workings of a mobile network and wireless internet network can be made to some extent, but the working of a wireless internet network is much more complex in nature. So, how does the wireless internet work?

How WiMax works
We can single out the WiMax (Worldwide Interoperability for Microwave Access) technology that is widely used for setting up wireless internet. High speeds can be achieved over a wireless network using this technology. Based on the IEEE 802.16 communications standard, this technology if fast replacing cumbersome cable and expensive satellite networks.

The WiMax network consists of base stations (similar to mobile towers) set up by the service provider, and a receiving antenna (similar to a mobile phone antenna) at the user end. The user pays the service provider for wireless internet access, just as they would for a normal internet connection via a cable network. The service provider provides the end user with the software, a login and a password. Most of the laptop manufacturers today equip high-end models with a built in antenna bundled with the required software for the unit to be WiMax compatible. The service provider beams the internet signals from the base station. The antenna at the user end catch the signals, providing uninterrupted internet as long as the signal is available. With a laptop equipped with an antenna you could be connected to the internet wherever the signal is available from the base station. As with mobile phones that catch a signal from the nearest tower of the particular service provider, so is it with new generation WiMax services. One WiMax base station can send signals over distances of several miles depending on the terrain. The more flat the terrain, more the coverage. Once you move from one base station area to another, your laptop receiver will hook up to the other base station (of the same service provider) with a stronger signal. As WiMax service providers spread out their operations, everyone will be connected to really high-speed internet 24X7 wherever they are.

Other common uses of wireless internet
Wireless internet is not limited to WiMax. Most of us have used some sort of wireless internet some time or the other. GPRS (General Packet Radio Service) is one such example. When a mobile user subscribed to the GPRS service, the receiving mobile unit could receive voice as well as data signals. In simple terms, the mobile phone could be used as a phone for voice calls and also as a modem to connect to the computer to surf the internet. The only limiting factor here was the speed which was very slow. This technology was gradually replaced by the EDGE (Enhanced Data Rates for Global Evolution) technology. EDGE was an enhancement over GPRS, able to provide more capacity for voice traffic and at the same time have high-speed data transfer capabilities.

EDGE technology has recently been replaced by the 3G (Third Generation) technology. Speeds of over 2Mbps are attained using 3G technology. These speeds will keep on increasing with advancing technology. 4G (Forth Generation) will be the next main change in this domain. 4G research is being carried out, but no frequencies have yet been allocated for this technology. Estimates are that 4G will be implemented around 2010-2012, but with the speed at which technology is advancing, it could happen earlier.

Conclusion
Mobile phones have passed the stage where they were used to just make and receive calls. Today one can buy mobile phones that do almost everything that your personal computer or laptop can. Operating systems can be loaded onto mobiles, virtually making them one instrument for all your phone and computing needs. This is where wireless internet will play a major role in the future. It will connect you 24X7 with virtually no breakdowns.

Cables will still be used for the internet till the time wireless internet can match data transfer speeds of cables. Once this happens, technologies such as WiMax and 3G will help in making this world a 24X7 connected, wire-free world.

Wireless internet connections have many advantages. If you are a businessman and run your own business then WiFi is the best solution to access internet and manage your business when you are away from your desk. Even if you are a common user, wireless connection is a good opportunity to chat to relatives, friends, being able to read your mail letters when you are on your holiday and just surf some interesting sites. Positive and practical sides of wireless networks are mobility, rapidness, security and attainability to distant places.

Over the last years broadband width for Wireless networks has considerably increased. This growth rises due to up-to- date technologies and modern devices like mobile phones, laptops, personal digital assistants, iphones, iPods etc. Network by wireless has become faster and more reasonably priced thanks to progress in the bandwidth arena. Now it can transfer data up to two megabytes per second, as usually in the past it was just one megabyte. Furthermore, wireless broadband connection is more secure than a satellite one due to the fact that the signal does not travel in the process of transfer, but goes straight to the recipient. Also, you are pleased with the wireless connection’s speed while downloading web pages. It is rather easy to check your mail letters as well as send them. Interactive functions. Regarding applications like games, audio-video programs, chats, multimember chats, video-conference calls, local networking or wide area network are rather painless to navigate. On the whole, your computer usage becomes more and more efficient.

Wireless connection for rural users means internet access, high rate and comfort as no need to set up additional wires or lines. By the way, you can install such a wireless internet connection so that you can access it within a one-hundred foot radius. Thus, you can move your laptop freely about the house or have a nice cup of tea in your arbor enjoying internet surfing. Now it is no need to sacrifice internet connection if you want to move to another room. Wireless networks means work well for a businessman. He/she can contact any person anytime and anywhere. This is a big advantage. Almost all new PCs have already installed wireless chipsets that allows you to connect internet automatically. It saves you time and does not involve devices or cables. Also any Bluetooth works simply with the wireless connection. To make our life easier, wireless technology enabled us with a wide range of new and advanced wireless gadgets like wireless microphones, wireless headsets, wireless stereo speakers, computer peripherals, televisions.

The leading UK Telecom company can provide you with a piece of advice on wireless broadband internet connectivity. Certainly, we can say that our generation steps a new era. This era is called Wireless Connection. Wireless connection spreads rapidly and we become a wireless society. Technologies for wireless are improving constantly. These described above advantages of wireless connection make our life less stressful. Moreover, it is very valuable and helpful in both professional sphere and personal life. Apply network by wireless and enjoy your life!

I am currently using DSL Router with 802.11N network. So is my notebook.
My notebook is using the Wireless-N adapter as the notebook’s build-in wireless adapter comes with 802.11g standard.

I have been looking around to get a wireless internet camera with 802.11N network. The purpose is to maximise the bandwidth for my wireless internet camera without any lagging of the video signal.

However,currently, on the market, it seems that there is no 802.11N standard wireless internet camera available yet as far as I am concerned.

Most of the internet camera comes with wireless or wired R45 network connection and are in 802.11b or 802.11g network.

I have checked with the Dlink,,Linksys and other distributor and find that there is no offer for 802.11N. SInce I needed the wireless internet camera urgently, I have no other alternative but to purchase the wireless internet camera with 802.11g standard.

I have purchased the Linksys WVC200 Wireless -G PTZ internet camera as showed above. To know more about this product,Click here.

This camera provides both wireless and wired network connection.
It has high quality video,flexible control remotely with Pan, tilt , and zoom.
It works terrific.The price is also quite competitive.

There is not much of video lagging when you control the internet camera remotely from outside of your office provided the camera is connected in the wired network to your router by mean of R45 cable. However, if you connects the internet camera to the router wirelessly, and you try to control the wireless camera remotely outside from office, there seems to be some video lagging problem. The reason why I need to do this is due to my router is not in the same room as the wireless internet camera.Moreover, the room where the wireless camera is doesn’t have the network point (Rj45 socket).

I knew there is no much I could do as there is a limitation of the 802.11g network.
It can only achieve a maximum throughput of 54 Mbytes wirelessly no method how good tuning you can do with the camera resolution and other features.

However, desperately to solve this video lagging’s probem, i checked in the market to see if there is any gadgets that could help to solve this issue.
Then I came cross a product called HomePlug AV Ethernet Adapter from Shiro which eventually solve my problem. It boost up my wireless internet camera signal up to 200 Mbytes which resolve the lagging problem.

This adapter also save you the hassle of the physical network wiring. It can also be use to connect between any network devices ie. printer server,wireless game adapter, wireless camera etc to the router wirelessly.

The adapters work in a pairs.Let assume that the wireless router is in room A and the wireless camera is in room B. In room A, you will connect one end of the adapter1 to the power source.

From the adapter1, link its network connector (using RJ45 cable) to one of your router port.From room B, do the same thing, connect the adapter2 to the power source.From adapter2, link its network connector (using RJ45 cable) to the wireless internet camera.

The adapter is not strictly to be used for router only.Basically, you can connect remotely between any network devices together.

The adapter make use of your in-house power circuit to transforms into a high speed wireless broadband and network backbone for transmission of digital data, voice, audio and video.

In this way, the adapter allows me to connect my internet camera wireless without short chain the bandwidth performance of my DSL network.

The model which I purchase is Shiro HL109E as showed on the right.
I believe there may be some similar product available.However, so far only this product offer the Powerline Networking up to 200Mbps.
