Corporate Overview
Tropos Networks is the market leader in wireless broadband networks enabling
enterprises to own and control a smart, affordable, IP infrastructure that provides
a cost effective foundation for securely and reliably deploying multiple high-value
applications. Municipalities use Tropos to improve the efficiencies of mobile workers
and for improving resource conservation. In harsh outdoor industrial environments
such as shipping ports, mines, and construction sites, Tropos networks are used for
applications such as video security and for improving operational effectiveness.

Tropos has more than 500 customers worldwide and a growing list of solution partners
that provide best-of-breed complementary products to help customers implement
complete solutions.

HIGH VALUE MUNICIPAL APPLICATIONS
Tropos solutions are used today to deliver a range of metro-scale Wi-Fi applications
that improve mobile workforce efficiency, provide cost savings, and enable a broad
range of new data-, voice and video-centric applications. A single wireless broadband
inftrastructure can be used securely as the foundations for one or many high value
city services.

 · Public Safety ­ Providing mobile pubic safety workers with high-speed access to
   information such as mug shots and fingerprints for improving safety within the community.
   Public safety productivity can improve 20% or more.
 · Video Surveillance ­ Enabling police to monitor areas (high crime, public schools,
   municipal buildings, etc.) or events from a remote location without increasing the
   workforce, and while providing hard evidence for court cases. Video surveillance can
   reduce crime rates by 50% or more.
 · Automated Utility Meter Reading ­ Centralized meter monitoring and management
   improves resource conservation, reduces operating costs, enables faster and more
   accurate pinpointing of outages and leaks, and results in better customer service.
 · Intelligent Transportation Systems ­ Improving traffic flow, reducing vehicle
   emissions, and synchronizing the timing of traffic signals to expedite the way for public
   transportation and emergency vehicles are just a few of the benefits of an ITS system. In
   addition, video applications can be added to the network for traffic observation as well as
   public safety applications such as red light runner monitoring.

 · Mobile City Workforce ­ Enabling access to office applications from the field ­ the ability
   to complete and file reports and download information improves their effectiveness
   in serving the community. With more than 50% of city workers mobile, this can mean
   significant savings.
 · Extended College Campus Access ­ Complimenting existing campus networks and
   extending outdoor Wi-Fi reach to almost anywhere around town. This keeps students
   connected with their schools and provides flexibility in how they learn and play.
 · Digital Divide - Provides a valuable resource that can improve quality of life in under
   privileged communities, encouraging education, computer literacy, and economic
   development.


TECHNOLOGY
Tropos MetroMesh is the first wireless picocell architecture purpose-built from the
ground up for delivering low-cost, high-capacity, high coverage fixed and mobile
broadband on a metro-scale. It has been enhanced and refined based on experience
from customers using the network in a wide variety of applications and terrains.
MetroMesh fractionalizes backhaul, self-configures and self-optimizes, collects and
analyzes performance and activity data and ensures reliable client connectivity in
unlicensed and licensed spectrum. MetroMesh easily scales to thousands of Tropos
routers covering hundreds of contiguous square miles.

Tropos has proven that MetroMesh delivers industry leading symmetrical client
throughput at the lowest total cost of ownership in the world's largest metro-scale
Wi-Fi mesh networks in operation today.

Our patented MetroMeshTM architecture features unique technologies that set us apart
in the industry. This includes:


 · Predictive Wireless Routing Protocol (PWRP)TM ­ intelligent software that creates a self-
   organizing and self-healing wireless mesh network that intelligently selects the optimum
   end-to-end path through the mesh.
 · Advanced Mesh Connectivity (AMCE)TM ­ compensates for Wi-Fi client variations thereby
   improving connection reliability.
 · Spectrum and Application Based routing Engine (SABRE)TM ­ provides rule-based routing
   and traffic segmentation, allowing assignment of traffic to particular radio interfaces
   under certain user-defined conditions.
 · Mesh Edge System Management (MESM)TM IP Services Software ­ builds secure, multi-use
   networks and applies QoS and mesh edge airtime limiting.

 · Virtual Radio Interface ­ Provides multi-protocol radio support to bring the benefits of
   MetroMesh to new radio technologies.
 · Correlated Mesh Data Protocol (CMDP)TM ­ Distributed pre-processing with centralized
   collection and correlation for efficient optimization and business analytics.
 · Tropos Outdoor- Optimized Router Family ­ Tropos designs its own RF power amplifiers
   and router hardware to ensure best coverage, highest link reliability and lowest MTBF in
   the industry.
