Cisco Systems has agreed to buy Navini Networks, a developer of WiMax broadband wireless access systems.
The US$330 million (NZ$435 million) deal marks Cisco's first foray into the technology.
Cisco says it is particularly interested in Navini's expertise with "smart beamforming" technologies used with Multiple-Input, Multiple Output (MIMO) antenna arrays, which in wi-fi systems allow base stations to handle much higher data throughput.
Cisco plans to fold Navini into its wireless networking business unit. It expects the acquisition, its 124th, to close by the end of January.
