NextHop Technologies., a Mountain View, Calif. provider of WiFi and other network software for large companies, said it has raised $4 million in a fourth round of financing.

Investors included New Enterprise Associates, Duchossois Technology Partners, Labrador Ventures, and Parker Price Venture Capital. The company’s total funding is $45.8 million.

From the company’s statement:

“Corporate Wi-Fi initiatives are expanding as companies realize increases in worker productivity gained from wireless deployments,” said Dan Phelps, general partner at Duchossois Technology Partners. “NextHop enables wireless solutions that integrate seamlessly into the existing network infrastructure, rather than burdening IT staff with an overlay network, to achieve the efficiencies of a mobile workforce with a more cost effective solution.”
