Siemens Venture Capital Makes Strategic Investment in Tropos Networks; Companies Will Team to Accelerate Adoption of Tropos MetroMesh Systems in New Markets Around the World.

SUNNYVALE, Calif. -- Tropos Networks, Inc., the leading supplier of equipment used to build metro-scale Wi-Fi mesh networks, today announced that Siemens Venture Capital, a subsidiary of Siemens AG Siemens AG

German electrical-equipment manufacturer. The first Siemens company, Siemens & Halske, was founded in Berlin in 1847 to build telegraph installations.
, has made a strategic investment in Tropos. In this context, the Siemens Communications Group will evaluate Tropos MetroMesh systems for use in new geographic and vertical markets. Terms of the funding agreement Funding Agreement

 were not disclosed.

"We are pleased to make this strategic investment in Tropos Networks, the clear leader in the metro-scale Wi-Fi mesh networking Mesh networking is a way to route data, voice and instructions between nodes. It allows for continuous connections and reconfiguration around broken or blocked paths by “hopping” from node to node until the destination is reached.  system market," said Louis Rajczi, Vice President & Investment Partner, Siemens Venture Capital. "We look forward to teaming with Tropos to facilitate adoption of their fast, low-cost and simple MetroMesh systems in new geographic markets, as well as in vertical markets such as carriers, intelligent transportation systems and energy production and distribution."

Christoph Caselitz, President of Mobile Networks at Siemens Communications, said, "Mesh techniques represent the next logical step in development for Wi-Fi radio networks, as can now be found in ever more offices, homes and public buildings. Here we see a lucrative market for service providers and mobile operators."

"Siemens' investment is another indication of the exceptional opportunity in the metro-scale Wi-Fi mesh networking market and of Tropos' leadership within that market," said Ron Sege, President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board.  of Tropos Networks. "We look forward to working with Siemens to further expand our already unmatched installed base of 200+ customers in more than 25 countries. This strategic partnership will help to accelerate our growth by developing additional geographic markets worldwide and selling into new application spaces, including the carrier market."

Metro-scale mesh networks deliver city-wide fixed and mobile broadband Description
Mobile Broadband is a type of wireless internet access that differs from Wi-Fi.

Mobile Broadband is the name used to describe the 3G services which are made possible by HSDPA and HSUPA, the latest technologies on the W-CDMA evolutionary path.
 access via a scalable, reliable and secure Wi-Fi infrastructure. Mesh routers form a self-configuring and self-healing wireless broadband High-speed wireless transmission of data. What is "high" speed is always a changing number. Wireless systems are typically slower than land-based, wireline networks. In the past, wireless broadband started at 250 Kbps, whereas land-based broadband was generally considered to start at T1  data network that dynamically self-organizes as routers are added or subtracted, backhaul supplied or removed, and interference comes and goes. The network forwards client data from mesh router to mesh router to a wired Internet connection. The result is a large scale Wi-Fi deployment with high throughput that does not require wired backhaul to each access point, installer truck rolls or expensive and complex client devices and software. A Wi-Fi mesh network can be deployed at a multi-square-mile scale in a matter of days, providing a broadband experience indistinguishable from indoor wireless and wired networks.

Tropos MetroMesh routers quickly and economically use the intelligent Tropos Predictive Wireless Routing Protocol The Wireless Routing Protocol (WRP) [1] is a proactive unicast routing protocol for mobile ad-hoc networks (MANETs). WRP uses an enhanced version of the distance-vector routing protocol, which uses the Bellman-Ford algorithm to calculate paths.  (PWRP PWRP Predictive Wireless Routing Protocol (TM)) to provide pervasive coverage over metro areas. PWRP forms a wireless mesh See wireless mesh network. , dynamically routing traffic along the highest throughput path to an Internet connection. This intelligent routing negates effects of radio frequency (RF) interference, backhaul failure and mesh router failure. PWRP scales to thousands of nodes with the lowest routing overhead in the industry. Network support costs are minimized via the central management capabilities of the Tropos Control element manager, a configuration, monitoring and maintenance tool. The result is unprecedented bandwidth on the street, easy and low cost installation and operation, and true metro-scale coverage.

Metro-scale Wi-Fi mesh networks implemented with Tropos MetroMesh routers allow public safety agencies, municipalities and service providers to quickly and easily deliver city-wide fixed and mobile multi-megabit connectivity for IP-based voice, video and data applications.

About Tropos Networks, Inc.

Tropos Networks is the proven leader in delivering truly ubiquitous, metro-scale Wi-Fi mesh network systems. We deliver the fastest, lowest cost and simplest wireless broadband access solutions, as demonstrated by the world's largest installed base of metro-scale Wi-Fi mesh networks. Our innovative MetroMesh(TM) architecture with our patented Predictive Wireless Routing Protocol (PWRP(TM)) allows public safety agencies, municipalities and service providers to quickly and easily deliver city-wide fixed and mobile multi-megabit connectivity for IP-based voice, video and data applications. PWRP is the first and only metro-scale optimized, radio-agnostic, wireless mesh routing protocol A formula used by routers to determine the appropriate path onto which data should be forwarded. The routing protocol also specifies how routers report changes and share information with the other routers in the network that they can reach. , which does with routing software what other approaches attempt to do with expensive hardware. The result is 10x better price/performance than any other approach to the broadband last mile. Tropos Networks is headquartered in Sunnyvale, California Sunnyvale ([sʌniveil]) is a city in Santa Clara County, California, United States. It is one of the major cities that make up the Silicon Valley. As of the 2000 census, the city population was 131,760. . For more information, please visit, call 408-331-6800 or write to
