News, stock information, receive and send e-mail, weather updates, internet and more all at your finger tips. The iPhone is a device which can do all of this and because of its internet access can also do so much more. The iPhone is a highly useful piece of technology for many organizations and personal users. The iPhone has been out for about 8 months and is one the of the most sought after mobile devices on the market. It is a touchscreen phone with nearly all the capabilities of a home computer, iPod and camera. The iPhone has the ability to access the internet the click of a button almost anywhere the user wishes and uses EDGE technology. EDGE stands for Enhanced Data rates for GSM Evolution. It is is a digital mobile phone technology that allows increased data transmission rates and improved data transmission reliability. There are maps available which make it virtually impossible to get lost in any circumstance and clients have company information available whenever they need it.
The advantages of the iPhone are obviously visible to the user. You are able to download pictures and document, send and recieve e-mail, text message, call, visual voicemail, internet access. Some disadvantages are that it is susceptible to crack and scratches if it does not have the proper covering, the touch screen may be difficult to use for some people. A third disadvantage is that in some closed networks, such as universities and schools, it is hard to access wi-fi internet through the iPhone. Lastly, the iPhone is very pricey. The smallest gb phone today, is $399.
In the area of organizational communication, the iPhone can do wonders for a company and its clients. All the features listed above make it easier for customers , businesses and employees to communicate on a much broader scale. No longer do clients have to wait a day or so for answers to their questions, but they can receive answers right on their lunch break from their cell phone instead of having to be in an office. Information can be received from anywhere in the form of pictures, word documents and other such files. It enables news, information and company statistics to be available right away.
Having had access to the use of an iPhone, I would rate its usefulness as a 5.

Wi-Fi

Wi-Fi, short for Wireless Fidelity, is a wireless technology owned by the Wi-Fi Alliance that allows for the flow of information while being completely mobile. The Wi-Fi Alliance is a group of independent companies that collaborate the connectivity of wireless technologies. Society has become accustomed to 'plugging in' whenever we want to connect the Internet but soon it might just be a matter of which direction you are facing. Since 1997, the use of wireless technologies has sprawled and it seems that we have only scratched the surface of the limitless possibilities of its uses. Companies such as Intel are currently developing high-performance wireless communication that will significantly broaden the reach of Wi-Fi. The future of wireless is not going to be about its fancy gadgets. As Intel states, "It's going to be about a wireless society." This would be on a global scale and would allow people to exchange information seamless as they move from place to place.

The advantages of having this technology in an organization are invaluable as they cut costs and free up time for those that use it. It allows you to communicate without being tied down by cables and with the right technology, you can be in touch with the world anywhere you need to be. Most new computer technology, such as laptops, already have Wi-Fi capability built in standard so there is little or no extra cost. There are also hundreds of thousands of public locations that currently have Wi-Fi connections that are easily accessible. With faster communication, organizations can quickly and efficiently execute their business.

Although there are many possibilities for Wi-Fi, there are still limitations and disadvantages of the wireless technology. As its popularity grows, so will its volume of traffic and users. This will inevitably slow its performance if we cannot keep up with its growth. Wi-Fi also requires more power which pushes for better battery technology which can drives up expenses. And then there are the more obvious flaws such as natural barriers that limit connectivity, range of the connection and technology failures.

Since this is still a developing technology, any one of these advantages or disadvantages could intensify or disappear completely. Wi-Fi technology should be rated very highly on its usefulness in an organization as long as the company has the technology and knowledge to support it.
