M signed an agreement last week to develop and build high-quality, IP-based wireless networking infrastructure for the telecommunications industry.
Under the 10-year deal, Motorola's network solutions division will invest up to $1 billion (£0.6 billion) in mission-critical software from Sun and hardware from Motorola's own computer group.
Sun Solaris president John McFarlene said the companies hope to build highly reliable and scaleable systems that offer the "Internet equivalent of dial tone."
He continued: "Both companies share a vision of millions of access devices getting onto these networks."
Motorola said the jointly developed architecture would allow wireless service providers to respond to the growing market demand for IP-based voice, video and data services.
Products will be targeted at top-tier base station operators, call processing controllers, back-office processing and central office operations.
The first products of the venture are expected to hit the market next year, with volume shipments likely to begin in 2001.
They will be sold by the Motorola networks group, which specialises in building analogue and digital cellular networks for telecommunications providers.
Motorola chairman Chris Galvin said the alliance would help the wireless industry offer more reliable, lower-cost services to users.
The goal, he said is to "deliver the most reliable, scaleable and feature-rich wireless services available".
Sun CEO Scott McNealy said the agreement would spur innovation in the wireless communications industry.
"The new platform will be open," McNealy said. "Voice, IP and multimedia will converge. Customers will have more choices."
The architecture will include customised hardware from Motorola's networking division, Motorola's CPX8216 PowerPC computing platform and Sun's Chorus and Solaris operating systems and the Java Dynamic Management Software Kit.
