Aperto Networks, a maker of broadband wireless access systems, this week announced it has received US$20 million in new venture funding.
The funds, which the company says will be used to expand sales, support and product development efforts, bring total funding for the six-year-old company to US$77 million.
The latest round was led by JK&B Capital, though it also included previous investors such as Canaan Partners and Tyco Ventures.
The company's 802.16/WiMax base stations and subscriber units are sold to service providers, which offer business customers T-1, fractional T-1, wireless VPN, hotspot backhaul and disaster recovery services.
Aperto claims to have 120 service provider customers in 40 countries using its last-mile technology, which runs in the 2.5-, 3.5- and 5.8-GHz bands. Aperto offers point-to-point and point-to-mulitpoint products.
