Spirent plans to buy wireless performance technology specialist SwissQual for up to $72 million in cash. The acquisition is also a move to position Spirent strongly against rival testing company Agilent Systems. SwissQual sells systems that help carriers monitor their networks and also tests wireless and fixed network equipment in labs. One of its products is a probe that resides in a handset and assesses QoS for services received by the end device. SwissQual currently claims customers like Vodafone, Telecom Italia and France Telecom.
