Motorola Mobility Holdings Inc. (MMI) didn't wait long to make a splash as an independent company, unveiling its first tablet and several smartphones as it jumps on the 4G bandwagon.

Chief Executive Sanjay Jha unveiled the first tablet, the Xoom, which runs on the latest version of Google Inc.'s (GOOG) Android software. In addition, he unveiled the Droid Bionic, which will run on Verizon Wireless's fourth-generation network, and talked up the Atrix 4G, which will run on AT&T Inc.'s (T) newly redubbed 4G network.

These devices will serve as a barometer for how Motorola will compete as a smaller, standalone company. Wednesday marked its second day as a public entity, as the company now faces off against other behemoths in the smartphone and tablet business, including Apple Inc. (AAPL) and Samsung Electronics Co. (005930.SE), which last year became the top manufacturer of Android phones.

While Jha acknowledged that size does matter for a technology company, he believes the more important factor for success is the ability to continue innovating, he said in an interview.

Still, Jha said Motorola plans to sell fewer smartphone models than the 23 it released in 2010, and that he would focus on products with a broader appeal.

On Wednesday, Motorola introduced the Xoom, which will run on Google's "Honeycomb" version of Android, which Jha said was better suited for tablets because it was designed to serve larger mobile devices.

The new operating system includes Android features such as widgets, multitasking, browsing and access to more than 100,000 apps on the Android Market. It also features 3D maps, a collection of more than 3 million e-books, and video and voice chat.

Initially, it will sell through Verizon Wireless as a 3G device in the first quarter, but Jha said the company plans to introduce a 4G version later on. Customers eventually will be able to take the 3G tablet back to Verizon Wireless stores to get it upgraded to a 4G connection.

Motorola wasn't alone in unveiling a tablet Wednesday. T-Mobile USA and LG Electronics Inc. (066570.SE) also joined the fray, unveiling a new tablet dubbed the G-Slate that is expected to go on sale in the coming months.

T-Mobile, owned by Deutsche Telekom AG (DTE.XE), said the G-Slate will be among the first 4G tablets to fully benefit from Honeycomb, the next version of Google's Android operating system that was designed from the ground up for devices with larger screen sizes than mobile phones.

"The T-Mobile G-Slate with Google will build on our rich history of Android innovation and leadership and deliver deep integration with Google services," said Cole Brodman, chief marketing officer of T-Mobile USA.

Jha said he expects many tablets to launch in the coming months. The trick is staying ahead and ensuring the right kind of carrier support and marketing, he said.

Motorola, meanwhile, also showcased a pair of 4G phones. The Droid Bionic is the latest device in Verizon Wireless's line of high-end Android smartphones. Jha said the company hopes to sell the device in the second quarter. It is the first of several devices Verizon Wireless is unveiling Thursday when it talks up its own 4G service.

The other was the previously unveiled Atrix 4G, which Jha showed off during an AT&T event earlier Wednesday. AT&T said it would be available in the coming weeks, and said the pricing would be competitive.

Both phones feature large screens and a dual-core Tegra processor from Nvidia Corp. (NVDA), promising higher speeds.

Moving in to 4G is crucial because carriers that are looking for a high-end phone and see one without 4G now consider it "lacking," Jha said.

Jha also unveiled a more standard smartphone, the Cliq 2, which will sell Jan. 19.

While much of the hype has been around the Xoom, Jha said that in the long run he believes the smartphone will still play a bigger role in the lives of consumers.

"The most compelling device fits in your pocket," he said.

Over the next few years, he sees the ratio of product launches to be roughly four to five smartphones for every tablet released.
