Sprint will lay off 91 employees in Bellevue and Kirkland as the fallout from its $3.5 billion purchase of wireless network operator Clearwire continues.

Overland Park, Kan.-based Sprint, which completed the purchase in July, also laid off about 160 people in Bellevue and Kirkland last fall.

The latest round of layoffs will occur in March, April and May.

Sprint has said about 75 percent of Clearwire’s pre-purchase work force eventually will be laid off.

The company says more than 240 Clearwire employees will remain with Sprint, mostly in Bellevue and Herndon, Va.

Separately, The Wall Street Journal reported this week that objections from antitrust regulators have led Sprint’s parent company, Japan’s SoftBank, to hold off on its pursuit of T-Mobile.

Sprint has been expected to make a move for T-Mobile since AT&T tried unsuccessfully to buy the Bellevue-based carrier in 2011.
