TROPOS NETWORKS JOINS JUNIPER NETWORKS J-PARTNER INFRASTRUCTURE ALLIANCE PROGRAM

Market Leading MetroMesh Architecture Coupled with Juniper's Products and Services Delivers Best-in-Class Solution to Evolving Municipal Broadband Market

SUNNYVALE, CA, March 7, 2006 - Tropos Networks, the proven leader in delivering ubiquitous, metro-scale, Wi-Fi mesh network systems, today announced that it has officially joined the Juniper Networks J-Partner Solution Alliance, a coalition of companies delivering products that complement Juniper Networks in delivering secure, scalable and high-performance IP networks. Tropos and Juniper will collaborate to deliver end-to-end solutions with unparalleled capacity and reliability for municipalities and service providers in the rapidly growing wireless broadband market.

"Juniper Networks welcomes Tropos, a leader in the municipal wireless marketplace, to the J-Partner Solution Alliance Program," said Tony Scarfo, vice president of Partner Management, Juniper Networks. "Our companies have developed joint solutions that we are taking to market. We look forward to working with Tropos to build metro-scale, Secure and Assured municipal wireless networks throughout the world."

This joint solution offers municipalities and service providers a flexible, carrier-grade solution for wireless broadband delivery. As part of the alliance, the companies will have co-marketing activities and joint sales engagements to deliver best-in-class product solutions of Juniper's security and IP routing with Tropos' metro-scale Wi-Fi mesh networking.

Deployed in more than 300 customer sites worldwide, Tropos MetroMesh routers quickly and economically use the intelligent Tropos Predictive Wireless Routing Protocol (PWRPT) to provide pervasive coverage over metro areas. PWRP forms a wireless mesh, dynamically routing traffic along the highest throughput path to a wired gateway. PWRP scales to thousands of nodes with the lowest routing overhead in the industry. Network planning, optimization and support costs are minimized via the capabilities of Tropos Control, a purpose-built element management system for MetroMesh networks, Tropos Insight, an advanced MetroMesh analyzer and optimizer, and Tropos Drive, a drive-test appliance to determine coverage and throughput in MetroMesh networks.

"This evolutionary partnership allows us to very effectively meet the needs of the growing municipal wireless market," said Chris Rittler, Vice President of Business Development for Tropos. "As the market expands in both size and expectations, we will continue to deliver the highest level of capacity, reliability and security without compromising the low-cost benefits of metro-scale mesh technology. The combination of Tropos' MetroMesh architecture and Juniper's comprehensive portfolio of routing, subscriber management and security products will enable the world's largest service providers to rapidly deploy scalable, profitable wireless broadband networks."
