Apple’s latest iPad dubbed as iPad 3 will have 4G LTE connectivity on both AT&T and Verizon Wireless, according to a Wall Street Journal report. iPad 3 is expected to be launched on March 7 and may include a quad-core chip and higher-resolution display.

According to the Wall Street Journal, which cites the usual “people familiar with the matter,” the hotly anticipated tablet will be sold with 4G versions that are capable of picking up LTE signals from one of the nation’s two top carriers. Verizon and AT&T both currently sell 3G versions of the iPad 2 that are equipped to run on their networks.

LTE technology is hardly omnipresent; by the end of 2013, 80% of the U.S. will be covered. When there will be no LTE available the iPad 3 will revert to 3G signal, which makes a lot of sense, the report suggests.We also anticipate that Apple will keep on selling the inexpensive Wi-Fi-only versions of the tablet.

The other problem with LTE, any user who has used a 4G smartphone, they have complained that
the battery backup of 4G is low. We will be interested to discover if Apple has figured a method to provide the much-prized 10-hour battery life which is fast becoming the industry standard for good tablets, not to refer smartphones while still supporting LTE. If so, we anticipate a 4G iPhone, the iPhone 5 most probably is not so far.

Around 200 million customers from US are in the Verizon LTE coverage area, whereas AT&T only covers around 74 million consumers with the 4G technology as AT&T has adopted the LTE technology late, having made a bet on a combatant 4G technology, HSPA+ but it is growing its network fast.
