Why Wireless?

Better value per $ over Fiber> For the same $ers you can now support more

applications with the same resources

Wireless provides capacity equivalent to Fiber

> 100x capacity of copper

Wireless supports mobility and NLOS

> Simplifies deployment

> Supports other applications like police, buses, trains

Why WORPdrive

WiFi based systems does not scale more than 5 to 10 clients

Heavy traffic deployments- performance starts to suffer from collisions

Lacks QoS over the air & ability to differentiate services

WORPdrive: Industry leading Highcapacity, high performance, wirelessbroadband

WOR`Pscale: Supports more total clientsand more simultaneous clients thanconventional solutions

WORPqos: over-the-air delivers highquality video & voice

Microwave &

Wireless Engineering Firm: Guarantee Peak Performance



23/29


Why Wireless engineering

Wireless Engineering firm deliver

design / build for ITS systems Understand best wireless technology for a given

application

Understand limitations of technology pre-

specified as part of a DOT request

Experienced in ITS projects ( Bid tocommissioning)

Demonstrated ability to work with ITS project

developer, General Contractorsm Engineering

firms, DOT

Capability to evaluate cost/performancetradeoffs

Cost effective pricing for equipment and hardware that supports the ITS project



24/29


Why Wireless engineering

ITS projects : consider the

intricacies of deploying wirelesssolutions

> Location, Height of towers, Line of

sight, atmospheric conditions

>Type of wireless technology Point

to point , Point to multipoint, Mesh

etc

Wireless represent 5% 10% of a

project costsand result in a 100% impact



25/29


Backhaul as reliable as weakest link

The Microwave component is the critical path foroperation and success of an ITS project

Backbone is only as reliable as its weakest link

> If there are 10 miles of communication backbone, with 9

Miles of fiber and 1 mile of Microwave wireless, thebackbone is only as good as the weakest link.

> Microwave link needs to engineered to be as reliable as fiber

Trend: More wireless implementations in ITS solutions

> Plan, design and build wireless solutions with reliability to

meet and exceed engineering requirements



26/29


Qualification for Engineering firms

Its critical that a wireless/communictions partner be brought

in at the very beginning, during the bid process.

Chose an engineering firm with demonstrated expertise and

understanding of latency, site/path surveys and true

microwave engineering.

> Ability to engineer across frequencies-licensed & unlicensed

> Varying atmospheric conditions Access to atmospheric refractivity

gradient data (extreme sub-refractive and super refractive atmospheric

conditions

> Microwave engineering across frequency and reliability across varying atmospheric conditions

> Capability to design/build complex wireless systems, install, commission

and network integration

Certified and trained by equipment provider

About Miller Electric

Miller Electric serves a wide range of customers on a variety ofprojects, including Commercial Office Buildings, IndustrialPlants, Data Centers, Universities, Hospitals, MilitaryBases, Entertainment Facilities, Roadways, and more.

Successful implementations of ITS Projects with wireless



29/29

Wireless ITS Project Experience

Experience working with MCIS and Proxim Miller Electric leverages Engineering firms to design and

deploy wireless

> Measuring the outcome with metrics

Key consideration and best practices for ITS projects

> If wireless is involved make sure you have a good partner that hasactual engineers specializing in microwave (not people who took a twoclass from a manufacturer)

> Bring them on right away so they can work with the engineering firm ofrecord and keep them involved at every step.

> Be very careful not to make any changes that could effect the wirelesswithout their approval (i.e. sites moving even a few feet can causemajor problems).
