A wireless router is basically a network device that lets you connect several computers to the internet without using a cable, but by using wireless access points, or WLAN. In essence, wireless routers allow the freedom of several users to be able to access the internet. Plus, wireless routers also free you from messy wires.

Basically, a wireless router works using signals that have the same radio frequency range as the wireless network card installed in the PC. The significant feature of this exchange of signal system is that both the router and the network card function on the same radio frequency range, thus allowing the transmission of data to and fro, between the devices.

In other words, the wireless router uses radio frequency range signals between devices instead of physical wiring connections to transmit signals. Being an intelligent device, a wireless router can determine whether a signal needs to be transmitted to a local computer on the internet or to the internet.

The signal’s strength is dependent on the manufacturer along with the internet signal strength that the ISP provides. A wireless network has the added functionality of providing security to the network with firewalls, security keys, and so on.

It is not difficult to set up a wireless network. All you need to do is connect the wireless router to your internet connection, and then just set up the drivers in your computer or laptop. You need not worry about anything, because the wireless router that you buy will come along with the drivers, manuals, and CDs, which will help you with the software and driver set up and the configurations.

Clearly, there are several advantages that a wireless router provides. The term ‘wireless’ is what it is all about. With a computer connected to a phone line or a cable, you get the sense of being tethered to a machine that is in turn tethered to a fixture or wall. This entails you sitting at one spot for a long time in order to do your work or access the internet.

But by fixing a wireless router, you can roam about all over your house, or even building, without having to remain connected to a cable modem or phone jack. This way, if for instance you prefer working outside, you will have the freedom to go out onto the deck, without needing to worry about setting up outdoor cables. If you feel like strolling down to your favorite café for a mug of latte, you can head straight there and surf the net while you wait for the brew to be made. These days, even airports allow you to surf the net without wires while waiting for your plane. Simply put, as long as you have a wireless router in place, especially a long range one, you can log on and surf the net practically from anywhere.

Not having to be tethered to a wall is particularly beneficial for employees or self-employed business people. Basically, any location can become your virtual office. With services and stores equipped with wireless routers, it’s easy to set up shop at any convenient restaurant like McDonalds or Panera. And in towns and cities with wireless facilities, access will spell freedom from the confines of a cubicle or tiny office. These days, more and more companies are allowing their employees the option of working from home.

Even as far as the sales force of a company is concerned, they can go from place to place without needing to return to the headquarters. Since the nearest Starbucks can be turned into a virtual office, business updates and sales reporting can be carried out via a laptop or PDA. This will mean more time being spent in the sales effort and less time being spent in the office.

The broadband router wireless VoIP technology is another great innovation. With this device, you can connect to the internet, using any ordinary phone device. You can then make calls to anybody in the world via your internet connection.

So do wireless communications have any drawbacks? Unfortunately, they do. Even though a great deal of flexibility and convenience is offered by this technology, some tradeoffs are there. A wireless network that is shared by all the users of a particular area has less bandwidth. This is felt most often where high-bandwidth multimedia applications or heavy file transfers are used. In addition, it is more difficult to secure wireless networks, plus, the installation of networking wiring to points of access requires coordination and long lead times with some combination of facilities maintenance and OIT. Hence, if you are thinking of going in for a wireless router you need to take the drawbacks into consideration.

Before buying a wireless router, it is best to check out the reviews about various brands in the market. There are many reliable and well-known brands such as Belkin wireless router, Netgear wireless router, and Linksys wireless router. Check out online to see which one will suit your needs, whether at home or in the office.

Wireless routers make life far more convenient and easier. You can go anywhere, without being restricted by wires and still be able to access the internet.

First, make sure your desktop PC is in good working order. What I mean by good working order is just to make sure the desktop PC is free of unwanted spyware and other harmful files which could make a desktop computer’s wireless connection slow down to a crawl. If you plan on making an older desktop PC wireless then you should really scan your computer for spyware and infections because the last thing you want is something stealing all your system resources when you don’t have very much to begin with.

WHATS NEEDED TO MAKE DESKTOP PC WIRELESS

Let’s start by assuming you already have an internet service (not dial-up) and are cruising the web with ease. You should have a cable modem connected to your desktop PC. If this is the case, then you’re ready to begin your wireless setup. If you don’t have an existing internet service and a cable modem then you’d better stop reading this because a wireless internet connection on your desktop PC can’t be accomplished legally without them.

MAKING PC WIRELESS – WIRELESS ROUTER

First, before anything, you need to purchase a wireless router. If you’ve never owned a wireless router before then grabbing the most expensive model probably won’t benefit you all that much unless you plan on receiving a wireless internet connection from inside of a multiple story building. In this case a more expensive router will offer a few features that are worth the extra money.

Remember when you go ahead and purchase a wireless router in hopes of making your desktop computer wireless you’ll be happy to know that you’ll be halfway done with your mission for wireless internet on your desktop. The only thing left is a wireless PC adapter.

MAKING PC WIRELESS – WIRELESS DESKTOP ADAPTERS

It’s actually very easy to add a wireless desktop adapter to your comupter’s arsenal of computing tools. There are two different types of wireless networking components that you can choose from. They are as follows.

2. Wireless PCI adapter

*both wireless devices are packaged with a setup CD-ROM which quickly installs everything needed to configure and use your PC’s wireless internet connection.

A wireless USB adapter is the easiest way to make a desktop PC wireless. The cons of using a wireless USB adapter are the signal strength which is considerably weaker than a wireless PCI card. Most people experience no problems with signal strength as long as they stay within range of the wireless router that’s sending out the wireless signal.

Basically, installing a wireless USB adapter plugs into any available USB port. In reality, it only takes a matter of seconds to plug in a USB adapter and start using the internet without the wires.

The second wireless device that can make desktop computers wireless is called a wireless PCI (PCI = white slots inside a computer) card adapter. This device enables high performance wireless connectivity for your desktop PC with extended range.

Installation is not as hard as you might have thought. Simply remove the side panel from your desktop PC and insert the wireless PCI card into any one of the white slots inside. There is only one way the card can be installed. Reading the directions that are included when you purchase your wireless networking device is by far the best thing you can do to ensure a smooth installation and launch of your wireless connection.MAKING DESKTOP PC WIRELESS

Laptops can be used to access the Internet and connect to Bluetooth enabled devices and wireless office networks wirelessly. Wireless technology uses RF signals transmitted over air. A wireless device is attached through a laptop wireless connection interface to a laptop.

In the case of both wireless Internet access and wireless access to a wireless office network from a wireless laptop, this distance limitation is normally 300 feet.

This can be extended through an external wireless RF signal booster antenna attached through a suitable interface on a laptop to about 3 miles. This antenna can also be termed as a laptop wireless booster. The wireless antenna uses signal gain control technology to extend the range of transmission of RF signals.

The wireless LAN or wireless LAN card alternatively on the laptop needs to be switched on and correctly configured as some of the prerequisite conditions for this connectivity.

An option for laptop wireless connection to the Internet can be an external USB wireless modem attached on a USB port of a laptop.

Bluetooth technology is a special application of wireless technology. It uses short-range RF signals at 2.4 GHz to achieve wireless signal transmission within a distance ceiling of 10 meters.

Through Bluetooth technology, a laptop equipped with an integrated Bluetooth adaptor (laptop wireless connection interface) can be wirelessly connected to Bluetooth enabled cellphones or barcode readers or to a Bluetooth base station within the prescribed distance limitation and data or files shared or transferred mutually between the synchronized devices at the two ends of the connection..

For the above to be achieved in practice, Bluetooth adaptors on devices at both ends of the connection need to be switched on and the necessary password permissions assigned on these devices.

The major advantage of a laptop wireless connection is ‘on the move’ seamless connectivity to the Internet, to wireless office networks, and to similarly equipped Bluetooth devices from a laptop. This provides convenience and independence to a mobile laptop user.

The benefits of a laptop wireless connection are manifold. Some of them include complete avoidance of unwieldy, expensive, and problematic wired connectivity on a laptop to achieve the same tasks, and wireless connection sharing facility among two or more laptops.

In the case of wireless connectivity to an office network from a laptop, wireless LAN on the laptop connects to a wireless office network through the internal antenna of an onboard integrated wireless LAN if so available on the laptop or alternatively through the antenna on the wireless LAN card if so available and inserted on the PCMCIA slot of a laptop.

With voice communications thrown into the mix, mobile users can stay in touch while roaming the property inside or out, and even on the road. The acceptance of the fixed to mobile convergence concept by the telecommunications industry only promises to fuel the fire for the adoption of VoIP over WiFi.

The Challenges of Implementing VoIP over WiFi Networks

As with any emerging technology, there are challenges to overcome. The development of the converged network, i.e. data and voice on the same IP based LAN, while yet to be an established norm, is proving to be beneficial for businesses from both a cost and productivity perspective. Adding the prospect of VoIP over a wireless network brings up a whole new set of issues.

VoIP is a time sensitive technology. Calls must be set up and authenticated, and voice packets must arrive at their destination without interruption and on time. This requires a near continuous network stream, uninterrupted by less sensitive data transmissions. The implementation of quality of service (QoS) techniques on wired LANs assure that these voice packets receive priority, and call quality issues such as latency, jitter, and packet loss have been sufficiently addressed.

Enter the standards based wireless network, a technology in an earlier stage of development, and more challenges occur. While today’s wired network provides plenty of bandwidth for both voice and data to coexist, WLANs provide less bandwidth, and quality of service issues must be revisited. Security measures such as authentication and encryption must be implemented and can add to the problem by increasing the size of the voice packet. Additionally, users on the move will traverse wireless access points where handoffs must be quick and smooth.

The IEEE 802 standards governing wireless technology are evolving rapidly and promise to deal with a broad spectrum of WiFi issues. Increasing the bandwidth available, prioritizing voice packets for QoS, authentication and encryption protocols for security, and enhanced roaming techniques are all being addressed.

Also in development is the wireless technology commonly known as WiMax, providing for the implementation of high bandwidth wireless communications covering distances of up to 30 miles. The evolution of WiMax could prove of great consequence to developing countries, as well as metropolitan LANs.

Security in a VoIP/WiFi Network

Companies wishing to implement wVoIP must take security issues into consideration from the start. As in any IP network, the dangers of hackers, denial of service, highjacking and spam, all lurk in the shadows.

Because a wireless network uses radio frequencies as its transmission media, the security normally provided by a firewall in a wired network is not sufficient, simply because of the physics. Whereas to break into a wired LAN requires hackers to either physically be inside the network or to hack in through the Internet, in a WLAN they can grab network transmissions from the air while parked across the street. The security issues that network managers must consider in a VoWLAN are the privacy of conversations, and the protection of the network infrastructure.

For WiFi networks, security has had a shaky start with the implementation of WEP as its security mechanism. WEP provides for authentication and encryption between the user and the access point, and was found to be easily hacked. The 802.11i standard, adopted as WPA2 (Wireless Protected Access), provides for more robust security by requiring two way authentication between the user and the network, and uses AES (Advanced Encryption Standard) as its encryption engine.

As network managers plan the rollout of a wireless VoIP network, the greatest security threat they face is improper implementation. Building security into the design of the initial deployment can, and should, affect the network topology, as well as material costs. Failure to do so could lead to further expenses in loss of services and network redesigns in the event of compromise.

WiFi, VoIP, and the Cellular Networks

Manufacturers of cellular devices are incorporating WiFi radios into their handsets at an ever increasing rate. New versions of mobile operating systems are coming out complete with a built in VoIP stack, inviting carriers and manufacturers to add VoIP functionality to their devices. Dual and quad band cell phones can choose between the strongest network available, cellular or WiFi, and place a call accordingly.

As cell phones become more like mobile offices, the benefits of a mobile work force become apparent. In the case of the road warrior, the ability to communicate via email, text messaging, video or voice, allows them to stay on the road longer without losing touch. In the age of instant information, mobile office applications allow files to be downloaded, edited, and uploaded, increasing the productivity of the traveler to the point where just about anything that can be done in the office can be done on the road.

A cell phone that can switch between cellular and WiFi networks can significantly reduce telecommunications costs at the corporate office. With WiFi hotspots popping up at hotels, cafes, and corporate LANs across the globe, mobile workers can stay in touch with office and family both on and off the job. With the addition of a VoIP service provider, cheaper VoIP calls can be made from any WiFi network at the push of a button.

Imagine, if you will, a future where one phone, with one phone number, can seamlessly traverse cellular networks, WiFi networks, cable and PSTN landlines. Where roaming and switching between disparate networks occur without interruption or loss of call quality. Fixed to Mobile Convergence is the buzzword of the decade, and the IP Multimedia Subsystem (IMS) architecture is the mechanism that promises to get us there.

The goal of IMS is to provide all the services and applications that the Internet provides, both current, and as of yet unimagined. IP based services such as VoIP, Push to talk cellular (POC), videoconferencing, text messaging, community services, presence information and file sharing, are just some of the possibilities. Designed to work with any fixed, mobile or wireless packet switched network, backwards compatibility for the legacy circuit switched phone system is provided through the use of gateways.

Although still in its infancy, IMS is already being implemented by AT&T as the platform in its newly acquired Cingular cellular network. Interest in investing in a new infrastructure by mobile and fixed operators has been up and down, as they weigh the costs and benefits of the new technology.

As the technology of VoIP over WiFi networks continues to develop, businesses of all sizes can reap the benefits of increased mobility, productivity, and significant cost savings. Standards committees are constantly working on ways to increase security and quality of service, and as fixed mobile convergence gains acceptance in the telecommunications industry, more choices in the services offered and the IP applications available to businesses are sure to follow. What will also be interesting to watch, is how these very bandwidth intensive applications will be priced by the carrier networks, and how it will affect the neutrality of the Internet.
