WiMax firm raises $20 million

Aperto Networks raised $20 million in a series D round of funding, bringing its total financing to $77 million. The Milpitas, Calif.-based company said earlier this week that JK&B Capital, along with Canaan Partners, Alliance Ventures, Innovacom, Tyco Ventures, Labrador Ventures and Satwik Ventures, pumped cash into Aperto.

The WiMax product maker will use the money to expand its sales efforts and further develop its technology portfolio. WiMax networks are expected to have a range of up to about 30 miles, with data transfer speeds of up to 70 megabits per second. WiMax is viewed as a cheaper alternative to digital subscriber lines and cable broadband access, because the installation costs of wireless infrastructure are minimal when compared with the wired versions.
