Network-equipment giant Cisco Systems is buying WiMax equipment maker Navini for $330 million in Cisco's 124th acquisition. Navini owns a number of patents related to their SmartBeaming technology that may give Cisco an edge in WiMax, a wireless-Internet technology with much longer range than Wi-Fi. Hopefully everyone has their tax documents in order — we hear that can be a problem at Cisco. Navini had been backed by Sequoia, among numerous others, but VentureBeat points out Sequoia declined to participate in its sixth funding round last May. Sequoia Partner Mike Goguen is a Navini board member and we presume Sequoia is glad to cash out if they didn't think the company was worth continued investment. (Photo by AP/Paul Sakuma)
