Brocade Communications Systems Inc. agreed to buy Ruckus Wireless for about $1.2 billion, the latest in a series of moves by network-equipment companies to expand their Wi-Fi offerings.

The deal, which values Ruckus at $14.43 a share, caused that company’s stock to jump 32% to $13.20 a share. Brocade’s stock fell 14% to $9.15.

Brocade, based in Sunnyvale, Calif., was originally known for networking hardware used in data storage applications. But the company has branched into other networking segments, including routers and switches sold in competition with the likes of Cisco Systems Inc.

Ruckus, also based in Sunnyvale, specializes in Wi-Fi gear used by companies and public venues. Its chief executive, Selina Lo, is one of a small number of female CEOs of publicly held tech companies.

The growing popularity of Wi-Fi has triggered other deals in the sector. Cisco, for example, in 2012 agreed to buy Meraki Inc. for $1.2 billion. Hewlett-Packard Co. in March 2015 announced a deal to buy Aruba Networks Inc. for about $3 billion; that business is now part of Hewlett Packard Enterprise Co. since the H-P breakup.
