TROPOS NETWORKS INTRODUCES FIRST METRO-COMPLIANT SPECIFICATION FOR Wi-Fi ACCESS EQUIPMENT

PePLink, Ltd is First Client Device Manufacturer to Adopt the Spec, Which Will Benefit Any Manufacturer's Mesh Solution

SUNNYVALE, CA - May 3, 2006 -- Tropos Networks, the market leader for metro-scale, Wi-Fi mesh network systems, today unveiled its Tropos Metro Compatible Extensions (TMCX) specification for Wi-Fi devices used for residential and business service. The TMCX specification will ensure the highest performance and reliability when third-party devices are connected to a metro-scale Wi-Fi mesh network, and will allow an exceptional level of integrated management, optimization and provisioning through intelligent MetroMeshT software tools such as Tropos Control and Tropos Insight. The TMCX specification is available to qualified manufacturers interested in developing client devices optimized for citywide Wi-Fi deployments, or those wishing to enhance their current product offerings. With the commitment and cooperation of client device manufacturers, the TMCX specification will further improve the end-to-end performance of all metro-scale Wi-Fi networks and further lower operating costs for service providers.

With the rapid growth of citywide Wi-Fi deployments, opportunities to offer Wi-Fi based residential broadband services are materializing worldwide. Many Wi-Fi enabled laptops and client devices lack sufficient transmit power and radio control software to send data reliably to an outdoor mesh through some types of building construction. They also generally lack the management intelligence to be monitored, optimized and maintained remotely by service providers. The requirements of the TMCX specification provide a blueprint to client device manufacturers allowing them to optimize their products for use in a carrier grade, metro-scale WiFi environment. These enhancements to the device's software intelligence, connectivity and manageability add significantly to the optimal operation and economics of a carrier-class broadband wireless network.

The first commercially available product to meet the TMCX specification for Wi-Fi client devices is the PePLink Surf 200BG. PePLink Surf easily connects citywide Wi-Fi service to individual households and businesses, and is a key component for enhanced user connectivity and reliability with citywide wireless high-speed Internet access. Its outstanding RF characteristics and management software suite ensure the best service for customers throughout a coverage area.

"As the fixed subscriber's gateway to the Internet, PePLink Surf's ease of use ensures a quick and plug-n-play set-up and a strong user experience," said Alex Chan, Managing Director of Hong Kong based PePLink. "Compliance with the TMCX spec, based on Tropos' unmatched deployment experience, enables PePLink products to provide best-in-class connectivity and manageability to metro Wi-Fi networks. The residents and businesses of cities with these networks will benefit from the increasingly reliable user experience obtained when using the TMCX-compliant family of PePLink products."

"Tropos is committed to the growth and advancement of the metro-scale Wi-Fi industry as a whole," said Chris Rittler, Vice President of Product Management and Business Development for Tropos. "The TMCX spec for client devices provides increased performance, reliability and manageability for metro-scale Wi-Fi networks. PePLink has demonstrated their commitment to this market through their impressive development of products specifically for metro-scale Wi-Fi. We expect additional device manufacturers to develop TMCX compliant products for the metro-scale mesh market as well, as the market is projected to top $1 billion by 2009.¹"

The PePLink Surf series for Wi-Fi includes the PePLink Surf 200BG and 400BG, with transmission power of 200mW and 400mW respectively. Both units support a wide range of features to meet the needs of service providers including secure authentication, data encryption, and optimized node and data rate selection.

Network Operators can remotely manage, monitor and provision the PePLink Surf through Tropos ControlT, Tropos InsightT and PePLink's carrier-grade management and reporting solution, PCMS (PePLink Central Management System).

The TMCX spec is available to qualified Wi-Fi device and chip manufacturers via Tropos' website at http://www.tropos.com/tmcx_application.html.
