iPad Models

I was impressed by iPad’s networking options and services. There are two versions available:

• Wi-Fi [802.11a/b/g/n]
• Wi-Fi [802.11a/b/g/n] + 3G

Besides Wi-Fi only model, iPad is also available in a Wi-Fi + 3G model for cellular network access from AT&T. The 3G radio version cost $130 more than Wi-Fi only version.

iPad’s Bluetooth Connectivity

iPad boasts Bluetooth version 2.1 + EDR (Enhanced Data Rate) Technology

Bluetooth 2.1 version has improved pairing experience for Bluetooth devices while increasing the use and strength of security as compared to older version of Bluetooth.The nominal rate of EDR (Enhanced Data Rate) is approximately 3 megabits per second, but practical data transfer rate is close to 2.1 megabits per second. Both Wi-Fi and 3G model support Bluetooth 2.1 + EDR Technology for  connecting wireless device like keyboard.

AT&T’s No-contract, 3G service

In the U.S., 3G service will be available from AT&T. You can choose from two data plans and the good thing about this service is there is no contract required. So basically you can use the wireless service as and only when you want it. In addition to this, AT&T data plans include unlimited access to over 20,000 Wi-Fi hotspots at locations including Starbucks, Barnes & Noble, and more.

The 3G plan offers data speeds up to 7.2 Mbps over 3G cellular networks around the world. iPad seamlessly switches between 3G and even faster Wi-Fi that way you always get the best connection available.

Super Easy Sign-up: So easy a cave man can do it

The service can be added or removed anytime right from iPad. No need to call or visit AT&T store.

How do you do it? from your iPad, tap Settings and choose Cellular Data. Then type in your user information, select a plan, and enter your credit card information. Like I said earlier, there’s no need to visit a store or call customer service.

You can monitor your data usage and change your plan at any time, including switching to unlimited data or canceling 3G service if you know you won’t need it.

Is the data plan required when I buy iPad Wi-Fi + 3G?

Absolutely no. You buy the wireless service only when you need it. You can just sign up for a contract-free data plan right on your iPad. If you ended up not buying the 3G data plan you can always use the built-in 802.11n Wi-Fi to access the Internet. I like this flexibility very much. Personally I would buy Wi-Fi + 3G model and start out with no data plan. I would watch my internet usage habit. If I feel I am out of Wi-Fi hot spot range some or most of the time, I would start out with 250MB/$14.99 data plan. If I still feel I am being left out and about without network I would upgrade myself to unlimited plan. Now one thing most people fear from a wireless service is what they are going to be charged for when they overshoot their data plan limit. Here is your answer from AT&T and Apple: As you get closer to your monthly data limit, you’ll receive onscreen messages to help you decide whether to upgrade to another 250MB or switch to the unlimited plan. You can also check your data usage anytime in Settings. You can drop the service if you think you don’t want it at this time.
