Cisco expanded its movement into wireless networks on Wednesday, acquiring Airespace in a deal worth $450 million.

Airespace, which is privately held, is a builder of wireless local area network (WLAN) gear for commercial and enterprise users. The firm is based in San Jose, CA.

Features of Airespace equipment includes wireless intrusion detection, a range of security applications, and what Cisco called “reduced operational complexity”.

Cisco said the acquisition would accelerate “delivery of key WLAN features and capabilities for Cisco’s entire customer base” and also allow it to “address a broader set of market segments.” Cisco added that Airespace’s engineering team’s experience would help expedite bringing new products to market.

Cisco will buy Airespace with stock. The deal is expected to close by April 30.

Airespace was launched in 2001 and has some 175 employees.
