Research In Motion Ltd., maker of the BlackBerry smartphone, plans to introduce a tablet computer in November to compete with Apple Inc.’s iPad, according to two people familiar with the company’s plans.

The device will have roughly the same dimensions as the iPad, which has a 9.7-inch diagonal screen, said the two people who wouldn’t be identified because the plans haven’t been made public. The device will include Wi-Fi and Bluetooth wireless technology that will allow people to connect to the Internet through their BlackBerry smartphones, the two people said.

RIM is racing to come out with a product to rival the iPad in the fast-growing market for devices that bridge the gap between smartphones and notebook computers. Apple, based in Cupertino, California, last month said it sold 3 million iPad tablet computers in 80 days after they debuted in the U.S.

“They can’t wait for a second generation of devices from Apple or they’ll fall too far behind,” said Ashok Kumar, an analyst with Rodman & Renshaw Inc. in New York.
