This is signficant because Trapeze early last year looked like it had "fallen off the trapeze," as Battery investor Tom Crotty put it to us.

At the time, Crotty was savoring the acquisition of Airespace, which was sold last year to Cisco for $450 million. A competitor to Trapeze, Airespace returned an early profit for Battery, and enabled Cisco to keep the lead in the so-called WLAN (Wireless Local Area Network) sector. The networks are sold to help companies to help them connect all their equipment, from phones to computers. Another company Silicon Valley competitor, Aruba, seemed to be getting more traction, and some say it is now considering going public. VentureWire (sub required) wrote a story about the Juniper investment in Trapeze this morning.

According to that report, Redpoint Ventures, Oak Investment, Motorola and Nortel Networks all participated. Founded in 2002, the company has raised a total of $97.5 million.

The sector has been revived lately with all the action surrounding WiFi, specifically the ability to route phone calls through such networks, including the use of VoIP -- and thus saving companies money. Trapeze has been helped by this trend, and has worked with new networking players like DiVitas.
