Steve Jobs the C.E.O of Apple Company has revealed the first Apple tablet PC on Jan 27th 2010 and named it iPad. IPad Technology is a lot like the previous product iPhone or you can say iPad is a stretched version of iPhone, but feature and performance wise it’s much exciting than an iPhone. It has a 9.7-inch long multi-touch screen with a resolution of 1024 x 768p, accelerometer (which let the iPad know when it’s being tilted), compass, Bluetooth, storage capacity – 16GB, 32GB or 64GB and Wi-Fi (802.11n standard) or Wi-Fi+3G. Apple iPad is powered by Apple’s own 1Ghz A4 (Apple A4 chip processor) chip.

The new communication technology or a new gadget in consumer electronicsmarket Apple iPad offers 140,000+ accessible apps to all its users, which means if you have an iPhone you can transfer its applications to iPad. The main interface of iPad has been taken from iPhone even the number of image icons are same. Apple put a feature called iBooks in iPad by which you can store, organize, read or buy any e-books. It also uses e-pub format. Of course also the Wi-Fi+3G function mentioned above with this function you could use Internet any time any place means even if you are not near any Wi-Fi hotspot. Apple also put forward special negotiated deal withAT&T for its user – 250mb data for USD 14.99/month or unlimited data for USD 29.99/month.

The bad thing about iPad is that it doesn’t have any camera and also it doesn’t support multitasking. Like iPhone the new IPad technology is also a closed eco-system means you cannot install or download any codecs. The cheapest iPad price$499 with a 16GB storage space and no 3G, but industry believe it is worth much more than this.

We may not be yet seeing Bluetooth 3.0 devices in the market but the specifications of Bluetooth 4.0 are already taking shape.

Power Consumption: Bluetooth 4.0 stresses on reducing the power consumption to fractions of what exists today. The power consumption would be low enough to be used in a range of low-tech devices such as pedometers, glucose meters, energy sensors, and Watches, all running from button batteries designed to last years.

Longer Range: The Bluetooth 4.0 specification also encourages the standard’s use at longer range, which will now be as far as 200 feet (61 metres), something very comparable to Wi-Fi.

Bluetooth 4.0 devices will likely use the low-power, single-mode approach, or integrate this into the established capabilities of Bluetooth devices as dual-mode products. Evidently, version 4.0 would get two variants in end-user devices: high power (PCs, headsets, phones, and cameras) and low power (a raft of low-power uses like in clock, watches).

Bandwidth: More powerful hardware can use the regular 3Mbps Bluetooth mode, now dubbed Classic, or else the recently introduced high-speed mode that uses 802.11g Wi-Fi as a carrier for its data. The technique extends the range to as far as 200 feet and up to the realistically achievable speeds of Wi-Fi. The SIG noted that Bluetooth 4.0 doesn’t have an arbitrary maximum range and can go further depending on the particular hardware.

When?

Bluetooth 4.0 is due for release this summer, but its very unlikely that we would see any devices that comply with the standard by the end of 2010. Q1 2011 would be the time we would start getting devices.

After the arrival more efficient ways like WiFi, Bluetooth has now become a niche restricted to phone headsets, a few keyboards and phone-to-phone connections, plus a few vertical markets, the technology is barely used by the general public. Bluetooth 3.0 tried to handle the Bandwidth problem, Bluetooth 4.0 would give it a competitive low-power operation edge over the WiFi counterparts, and would again revive the demand and use.
