To WIFI or Not To WIFI

Many people are confused with the huge amount of contradicting information on WIFI. I want to make this as simple as possible.

There are two main types of network setups. One is wired and the other is Wireless. WIFI is great for homes and small offices wanting a fast way to build a new network setup or upgrade an existing one. WIFI is especially good for families with multiple PCs wanting to share an Internet connection. But keep in mind that even though WIFI producing companies state that WIFI is secure, they don't hold a candle when it comes to cable based networks. Cable based networks are much more secure and offer higher transfer rates. On the other hand cabling needs additional work and planning to fully implement like trucking and In-wall Installation.

So if you want to install a WIFI DSL router for the soul purpose of sharing your internet connection amongst family members, then make sure to turn off File & Printing Sharing. This can be accessed from network connections located in the Control Panel.

In conclusion; data sensitive companies should stir away from WIFI for present time and the near future. But if WIFI is used just for sharing the internet connection, there would be no problem there. Home users can safely use WIFI but must make sure that no sensitive data resides on the PC (E.g. data from work) and secure the connection with a user name and password.

Another thing; always choose a Router over a Switch and a Switch over a Hub for cable based networks. The three devices mentioned earlier are all used to connect different computers together. But the Router is the most secure, smart and highly customizable of the three. The Switch on the other hand is easy to use with no configuration needed and costs so much less than a Router. Forget about Hubs they are plain stupid.

Wifi known as Wireless Fidelity allows a user to connect to the internet without using network cabling. Whether it's from your bedroom, couch, indoors or outdoors data can be sent and received within the range of a wireless base station. Wifi uses 802.11a or 802.11b technologies to provide a very reliable connection that is also fast and secure.

Wifi is available to every type of internet user and allows multiple users to connect to each other, other devices and the internet. However, your connecting device will need to have a Wifi certified card (PC Card or PCMCIA card) and it will connect to other certified products such as a base station or access point. It also saves on the cost and distance limitations of using cables, not to mention the unsightly look of running cables throughout an area.

These networks are very useful in the business and sales industry as they allow salespeople and travelers to connect to the network with ease and not be confined to one location to access applications such as email and databases. They allow business networks to easily expand and grow making a Wifi network a very useful technology in the business world. Businesses no longer need to abandon current network infrastructures and start over, they can simply use this wireless technology to easily change the network and allow for rapid growth.

Wifi networks work at the 2.4 or 5 GHz bands and possible speeds of 11 or 54 Mbps. Their speeds are very comparable to 10baseT networks and allow for easy network access. A Wifi network is essentially plug and play as you can turn on a certified device and connect to the wireless network providing you have the proper authentication and security credentials.

Wifi networks have security in the form of WEP (Wired Equivalent Protocol) that can provide the same level of security as that of a wired LAN. Wireless networks that are transmitted over radio waves are more susceptible to security problems, but WEP aims to provide security by encrypting the data sent over the radio waves.

Wifi (wireless fidelity) has brought a new dimension in the field of wireless networking. The transmission of data is done through the radio waves in the free space. It cuts down the cost of laying down the cables for network connections. Wi-Fi allows the user to access the Internet anywhere in or around the given location, but requires a separate Internet service.

These days Wifi hotspots are installed in various public places, where people can connect to the network such as, Libraries, Hotels, college campuses, office buildings, coffee shops, and many other public areas. That made business users who can gain extra work time, by squeezing in Internet time at various Wifi hotspots in need for the service.

Having a good Wi-Fi experience directly translates into a satisfying Internet experience. Hence we see that wifi has numerous advantages. If we consider the present world, we find that the demands for the wifi connections are increasing. People are beginning to appreciate the advanced features wifi network provides to the user. Due to its increasing demand the scope of the wifi network is also on the rise.

You can have a better speed of Internet connection by using wifi network. Since the bandwidth provided by wireless cutwork is large connection speed between two nodes is faster. It is also faster to transmit data between two devices connected through wifi. Wifi cuts down the cost of laying down the cable for network connection. With no wires attached it is possible that the sender node can be mobile. The equipments required to fully establishing the wifi network anywhere is relatively cheap. So the cost incurred in establishing the wireless wifi connection is cheaper and also very easy to install. Wifi established in small place do not even need the wireless routers.

Wifi is rather amazing, you can surf the world, download songs, send email and transfer files conveniently at high speed and at some distance away from your Internet connection. In addition you do not have to call or pay electrician to string the Internet network wiring in your home. If you wish to move your computer, you can just pick it up and make the move. Wifi is actually quite simple, useful and most of all convenient.

Now that you have your PSP, dont you wish you could change up your music files while on the go? Wouldnt you love to be able to access your iTunes library from anywhere, at any time without having to rely on a dedicated computer set-up.

Well, for a minimal cost (just under $25 USD) and a little tweaking, you will be well on your way to attaining the freedom of listening to whatever music you choose anywhere, anytime via your PSP WiFi internet connection.

These instructions are for MAC users and require the following three components:

1. A MAC using a minimum OS X 10.3,
2. Software (shareware) called Dot Tunes,
3. A PSP with the 2.0 firmware upgrade on board.

The simplicity and innovativeness of Dot Tunes provides you with the capability to peruse your own iTunes library where you can then generate a webpage that shows listings by album and/or artist and then access them over an internet connection. After generation, this webpage can be bookmarked and synced to the web browser on your PSP. Utilizing the Dot Tunes web-based interface, you can then simply browse to your desired song on the PSP screen and finally, download your choice to the Music directory on your PSP.

One thing that should be noted here is that the PSP is very particular about where various media is located and in which directories it can be placed. In order to listen to the song you are downloading, it must first be saved in the MUSIC directory, in a play list folder that already exists. To accommodate this restriction, you need to scroll through your music folder, go into an existing play list folder and save your selection there. Incidentally, you must also re-name the file extension (.m4u) to MP4 before your PSP will recognize it as a legitimate file.

Once you have accomplished the above, you are now ready to add/delete songs to your hearts content, anywhere there may be WiFi access (Increasingly WiFi connections are being made more readily available in coffee shops and other areas), and provided you have a WiFi connection on your PSP.

Because your MAC will be effectively acting as a web-server, it is essential that you set it up so that it will wake up for Ethernet network admin access in the Energy saving preferences on your computer.

Additionally, the port that the Dot Tunes page being served is accessible through must be an open port and not blocked by your Internet Service Provider. Plus, your router or computer firewall must not be engaged.

It is also a good idea to add password protection to the PSP connection so that you have the security in place that prevents others from accessing any iTunes libraries not DRM protected.

Here is the few know-how of the Wi Fi technology. Courtesy to wi-fihotspotlist.com.

A way to get Internet access, the term Wi Fi is a play upon the decades-old term HiFi that describes the type of output generated by quality musical hardware, Wi Fi stands for Wireless Fidelity and is used to define any of the wireless technology in the IEEE 802.11 specification - including (but not necessarily limited to) the wireless protocols 802.11a, 802.11b, and 802.11g. The Wi-Fi Alliance is the body responsible for promoting the term and its association with various wireless technology standards.

What is a Wi Fi Hotspot?

A Wi Fi hotspot is defined as any location in which 802.11 (wireless) technologies both exists and is available for use to consumers. In some cases the wireless access is free, and in others, wireless carriers charge for Wi Fi usage. Generally, the most common usage of Wi Fi technology is for laptop users to gain Internet access in locations such as airports, coffee shops, and so on, where Wi Fi technology can be used to help consumers in their pursuit of work-based or recreational Internet usage.

How Can I Use Wi Fi?

You must be using a computer or PDA that has Wi Fi connectivity already working. Most portable computers can add Wi Fi using an adapter that plugs into a PC card slot or USB port.
Will I need to have an account with a Wi Fi service provider? Generally, no. You should be able to sign up with the provider at the location. Many providers will display instructions when browser software opens on a WiFi-enabled computer. If you don't have an account, simply start your computer and make sure your Wi Fi card is plugged on. Then, open a browser.
