WiFi, the short form of Wireless Fidelity, is a technology that allows you to connect to the free bca final year projects internet without a cabled network. WiFi technology uses the 802.11 standard developed by the Institute of Electrical and Electronics Engineers (IEEE) and commercialized by the free bca final year projects WiFi Alliance.
Whether you are at home, your office cabin or another business location, using WiFi you can access the internet from your laptop or PDA as long as you are within the range of a WiFi access point.
What Happens
WiFi uses radio technology for communication, and mostly operates at 2.4 or 5 GHz frequency. Most of the free bca final year projects new connectible devices are today WiFi certified, which means not only that they are WiFi enabled, but also that these devices are interoperable.
In a WiFi network, computers with a WiFi network card can connect wirelessly to a WiFi router. The router is connected to internet using a cable or DSL modem. Any WiFi enabled connectible device within 60 meters or so of the access point can access the free bca final year projects internet.
Some WiFi hotspots are open in the sense that anyone with a connectible device within the range can access them, while some others are closed which means that only authorized users can access them using a password.
Interoperability is one big advantage of WiFi. WiFi allows users to connect with internet as well as with each other and other devices. It also helps you transcend the distance imitations of using cables and also saves some of the free bca final year projects cost.
WiFi technology is of special advantage to people in marketing and sales as these sectors involve a lot of travel. In fact WiFi can help anyone who has to move about a lot on work. They can access their work email or company databases from wherever they are using WiFi technology. Thus WiFi technology allows businesses to grow and expand fast.
Further, businesses do not have to throw away their existing network infrastructure to start on WiFi. It is very easy to integrate WiFi into your current wired network. This gives WiFi a definite cost advantage.
As we saw earlier WiFi technology uses the 2.4-5 GHz bandwidth and speeds ranging from10 to 50 Mbps. This is quite comparable to the free bca final year projects speed of a T1 line.
Security
All said and done, security is one of the biggest issues with a wireless network. This is all the more relevant in the case of a plug and play technology like WiFi. If you are not careful enough, anyone close enough to your base station can intercept the data you send and receive from your network or break into your system.
Therefore it is important to take sufficient security measures when you set up a WiFi hotspot at your home or office. Security is also applicable when you need to access a public hotspot using your laptop or other devices.
WiFi is Fast
WiFi typically offers much faster internet access than cable and DSL connections, a definite advantage for businesses. The free bca final year projects high speed is also useful when you’re on the move. There is a promise of enhanced productivity here.
WiFi is Convenient
You can access internet from your Wi-Fi enabled device from wherever you are, as long as you are within range of a base station or source. Thus the workers can move about with their gadgets from their cabin down the corridor to the conference room all without losing connection. You can also access your company’s network from your own laptop or PDA, even when you are in another place, like a business associate’s office, a hotel or convention center, as long as this place has a WiFi network.
It is also faster and more cost effective for the free bca final year projects company to set up a wireless network than a wired connection.
WiFi is Ubiquitous
The WiFi technology is already commercialized, so most of the computing and communication gadgets like laptops and PDAs come WiFi enabled. Further, these WiFi certified gadgets are interoperable regardless of the brand.
On the other hand, public WiFi access sites or hot spots are also on the increase. More and more offices, bookstores, airport lounges and food outlets are setting up WiFi hotspots in the hope that this will induce their tech-savvy customers to stay on. In some cities, entire neighborhoods and business districts are setting up bigger hotspots.
Drawbacks
The free bca final year projects small range is the biggest drawback for WiFi. Even while you can move about without the wires, the mobility is severely restricted. Most typically, it is about a radius of 100 feet or so from the hotspot.
Earlier versions of WiFi radios drain a lot of power, which is a disadvantage for laptops as they are battery dependent. Also, nearby equipment like microwave ovens and cordless phones can cause interference.
Security is another big threat. It is easy for anyone to access your wireless networks if you are not careful. Therefore it is important to install stringent security precautions depending on the free bca final year projects sensitivity of the information you handle.
What is a Wi-Fi phone:
A WiFi phone is a wireless device that gives you the dual benefits of wireless connectivity and the free bca final year projects cost savings of VoIP. It can be used in any areas- hotspots- where WiFi connectivity is provided. If there are no obstructions, you will be able to use a WiFi phone within a radius of 300 feet (90 meters) of the hotspot. However this also depends on the number of people accessing the hotspot at the given moment.
What a WiFi Phone Can Do
Just like a cell phone, you can use a WiFi phone to make calls, send text message, receive voicemail and to some extent even access the free bca final year projects internet. The WiFi phone is capable of retrieving data and accessing the internet better than a cell phone.
As wireless hotspots are becoming widespread, a WiFi phone enables you to converse with your family, friends and work associates anywhere in the world at much cheaper rates than a regular telephone allows. All you need to ensure is that you are within the free bca final year projects range of a WiFi hotspot.
In other words, you can use your WiFi phone from home, hotels, offices, airports, internet cafes, business districts or just about anywhere there is a WiFi network established. More and more metropolitan areas and commercial outlets are deploying free or low cost WiFi hotspots, so you have many places where you can use your WiFi phone to make and receive calls.
Most of the WiFi phone models available in the market have built in features like echo cancellation, lost packet recovery and packet delay compensation. Thus you can expect excellent voice quality from WiFi phones.
The free bca final year projects Hitch
The problem with WiFi technology is the range and this applies to WiFi phone as well. It is not possible to roam beyond the free bca final year projects hotspot, or between two hotspots, and this means limited mobility while you are on a WiFi call. Further, many WiFi enabled phones shut off the WiFi receptor when not in use, in order to save energy. This can lead to missing the incoming calls. However we can expect that these problems will be ironed out soon as the free bca final year projects technology develops.
The Bottom Line
