SAN FRANCISCO  T-Mobile is planning an aggressive push deep into the home with a variety of communications devices that will use Google’s new Android operating software that already runs one of its cellphones.

T-Mobile plans to sell a home phone early next year and soon after a tablet computer, both running Android, according to confidential documents obtained from one of the company’s partners. The phone will plug into a docking station and come with another device that handles data synchronization as it recharges the phone’s battery.

A T-Mobile spokesman, Peter Dobrow, declined to discuss the specifics of any future products but confirmed that T-Mobile had plans for several devices based on Android.

Last August, T-Mobile, the nation’s fourth-largest wireless carrier after AT&T, Verizon and Sprint, was the first carrier to sell a cellphone, the G1, based on the Android software, an operating system that handles the basic functions for mobile devices.
