The Apple phone has been an unbelievable success all around the world, outselling almost every other smartphone on the market and with the remarkable release of the 3GS in summer 2009 it seemed that Apple had even excelled themselves.

iPhone and Wi-Fi

To take advantage of the many iPhone’s finest features which includes Web browsing, checking stock, downloading your e-mail messages and receiveing maps and directions, you will have to have access to Internet. With iPhone you get two choices of internet access- everwhere and painfully slow or very fast and spotty, or the way they listed on the specs page of Apple, Wi-Fi and EDGE. Edge is a standard data on cell phones across almost all AT&T’s network. Every iPhone service plan is offered by AT&T provides unlimited usage of EDGE. Unfortunately it can be very slow, averaging in rates few more times faster in comparison to dial-up modems but far slower. Wi-Fi, is totally opposite though been very fast, also the Wi-Fi networks are reasonably common- at work, at home and there are many Wi-Fi hotspots. Regrettably AT&T doesn’t have access to Wi-Fi hotspot network in the iPhone plan.

Setting up wi-fi

Happily, your iPhone switches effortlessly between Wi-Fi and EDGE, this way you always have a backup plan if one network is not available you have the other. However you will want to be connected to Wi-Fi network when it’s possible. Your Wi-Fi settings can be accessed from two different locations, from the Settings screen or the Wi-Fi menu, or the Network screen in General settings. At this section you are able to turn Wi-Fi off or on. When on a “CHOOSE A NETWORK” page will appear, by default iPhone shows a list of wireless networks in range. If a password is required it will show a lock alongside them. You are able to gauge if you have a Wi-Fi signal by looking for the radiating line. You can speedily join any unprotected network by easily tapping on the name, but continue with caution. During research a flaw was discovered in iPhone which allows malicious Wi-Fi hotspot this take control of the iPhone.

Bluetooth and Netbooks

Bluetooth

Many netbooks tout bluetooth as one of their important features. But what exactly does bluetooth mean to you? Well, here’s the lowdown: In short, bluetooth is a wireless standard for exchanging data over very short distances -up to 32 feet or 10 meters. A bluetooth device transmits a 2.4 GHz radio signal, while other device receives the signal, both will start talking with one another.

Bluetooth is named after a Danish King Harald “bluetooth” blaatand. Of course Harald did not invent the wireless protocol – but he was known for unifying Sweden, Norway, and Denmark. Because the bluetooth inventors saw the protocol as a unifying communications standard, they wanted to honor King Harald. Obviously, the symbol on the bluetooth logo is King Harald’s initials in Nordic runes. It is a good way to replace data and peripheral cables. There are bluetooth-compatible mice, headphones, keyboards, printers, GPS receivers, cell phones, and PDAs. None of them need cables. One of the most useful features of bluetooth is calendar and contact synchronization among cell phones, laptops, and PDAs.  If you have a bluetooth-compatible cellphone, it’s possible to connect to the internet through the cellphone without data cable.

Remember that bluetooth transfers your files at a rate of 1 Mbps. Although that’s about six times faster than serial and parallel ports, it is substantially slower than an 802.11 Wi-Fi connection – you shouldn’t use bluetooth for your day-to-day Internet connection.

Even so, the next generation bluetooth Ver. 3.0, will amp up the standard’s data rate to a zoomy 24 Mbps. Other than the speed increase, the bluetooth standard will also offer improved power management capabilities, so new bluetooth devices can run longer on batteries.

If you don’t have built-in bluetooth in your netbook, but you are tired of those data cable, you can get an affordable bluetooth adapter (around $25) that you can plug in to a USB slot – you may need a driver to run your modem, but in most cases, Windows would automatically do it for you.

In Windows, you need to configure bluetooth before using it, just follow the configuration wizard to easily adjust the setting. You should choose the types of services you need, such as file transfer, PIM (Personal Information Manager) synchronization, headset, and so forth.

When the configuration is completed, Windows creates a ‘My bluetooth Places’ icon on the desktop. If you click the icon, a window is opened to control all bluetooth connections (you can also search for nearby devices). Another bluetooth icon is also placed in the taskbar for easy access.

Check the netbook’s user manual for more information on using bluetooth.  If you have a built-in bluetooth in your netbook, you should turn it off to improve battery life. Use a menu command or press a function key (check the user manual) to turn it off and on.

Facts About Wi-Fi Technology

Wi-Fi

Wi-Fi essentially is the technology that enables you to transmit information, images without the need for wires or VGA cables. It is the best option that enables you to get access to data of all kinds as well as images, videos without the need to put in place cabling, wiring, connectors and other paraphernalia normally associated with a wired service.

How does it work?

Wi-Fi makes use of a technology called as IEEE 802.11a or 802.11b. This means that speeds of 11Mbps or 54 Mbps can be harnessed as the network operates in a radio band that is unlicensed. This is the 2.4 – 5 GHz radio band.
This technology facilitates transmission of data almost ten times quicker than Bluetooth and has a much wider range as well. The technology enables you to connect many computers to each other seamlessly and with appropriate security. You can also use it to connect them to other wired networks.

What would you need to put in place a good Wi-Fi network?

The essential elements are an access point that is typically in the form of a LAN receiver and is also referred to as the base station. You then have Wi-Fi cards that can easily accept as well as relay signals. These cards can be fixed internally or externally to a laptop or desktop respectively. Certain safety features like firewalls as well as anti-virus programs need to be installed so that hackers are not able to get into the system and cause damage.

What are the limitations or disadvantages of this system?

Firstly, you could experience some interference in the airwaves that could reduce the performance levels. Secondly, the power consumption is much higher and that could push up your maintenance or operating costs. The limited range could also be something that may not appeal to many users.

However, considering that any Wi-Fi enabled gadgets like the PC, cell phone, MP3 player and the PDA can be connected to the internet at hotspots, the convenience of this technology is making it very popular. There are many hotspots that are being created by establishments like malls, cafes, restaurants, airports and other such public places so that users can do their work on the internet and do not have to depend on a wired connection.

It therefore appears that Wi-Fi technology will only become more and more popular in the coming years.
