FORWARD
• The RaptorX Wireless Waterway demonstration shows the
practicality of establishing and maintaining network
connectivity to multiple vessels in a NLOS scenario using VHF
and UHF TV Band Spectrum.
• Inland Waterways Transport play a critical role in moving
energy, food and industrial goods globally. Operationally
maintaining contact with these vessels is critical for the
safety and security of crew and cargo.
• On June 24 and 25, 2013 demonstration and field testing of
pre-production RaptorX Broadband Radios took place on
the Ohio River, centered at Georgetown, PA. This report
provides an overview of test and evaluation objectives,
measurement configuration and resulting performance field
performance.

Trial Performance Summary (see Figure 1)
•
The RaptorX Broadband Radio provided continuous broadband
connectivity over a 4.19 mile (6.72 km) stretch of the Ohio river based at
Georgetown, PA.
•
The average full-duplex payload data rate between the base station
and work boat ranged from 2.5 to 3 Mbps over a majority of the ship’s
track.
•
Payload Data Rates dipped to 760 Kbps at up and down river service
end-points, (Location 1 and Channel 2 End-point).
•
These data rates are sufficient to support a wide range of corporate IT
requirements, e.g. video conferencing, VoIP, file and messaging.
•
Quantitative data clearly showed the superior ability of White Space
spectrum together with Metric Systems’ RaptorX to deliver robust and
sustainable connectivity in non-line-of-sight and uneven terrain.

SUMMARY
Trial Objectives
•
Demonstrate continuous broadband IP connectivity over a reasonable span of the
Ohio River in line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios.
•
Back-up demonstration results with quantitative real-time data logs to validate
operation and support increased speed and service capabilities (see Figures 4,5).
Trial Set-Up (See figure )
•
Base Station – A RaptorX dual, parallel-channel White Space TV band base station along
with two (2)120° sector antennas were installed at the host operations building at
Georgetown, PA along the Ohio River.
•
Maritime Mobile Station – a RaptorX dual, parallel channel mobile station was platformed
on a river work boat. Two (2) Omni directional vertical antennas were installed on the
work boat pilot house deck railing providing port and starboard hemispherical coverage.

Performance Demonstrations
• Streaming multiple HD video downloads
(www.youtube.com) provided a qualitative
measure of performance.
• IPerf throughput measurements were
continuously run to assess throughput vs.
latitude/longitude.
• Receive signal strength (RSSI) vs. GPS tracks
were continuously logged to quantify nonline-of-sight service performance.
