Anritsu and TRX take indoor public
safety signal mapping into 3D
The National Fire Protection
Association adopted public
safety radio indoor
coverage requirements
several years ago that are
used for ensuring that first
responders have adequate
indoor coverage. Many
stakeholders, from building
owners to cities and their
first responders, need to
know that coverage
requirements are being met and have insight into coverage measurements throughout a
building or venue.
Ultimately, stakeholders want to know if a communications system will hold up when it is
most needed. Getting that information requires careful and accurate assessment of radio
frequency coverage, including positioning
information. But Global Positioning System (GPS)
signals are often unavailable or unreliable
indoors, making it difficult to conduct accurate
signal mapping. In addition, most indoor
mapping tools offer only a two-dimensional
mapping that may not capture the complexity of
environments such as elevators and stairways –
but these are locations where it's particularly
important for first responders to have good
coverage. Anritsu solves this issue of RF blind
spots with a three-dimensional, real-time approach
to signal mapping that was originally developed
to keep tabs on firefighters moving around
inside buildings.

"This technology came about from personnel tracking, and then
we saw a good fit for this technology for coverage mapping,"
said Wayne Wong, product manager with Anritsu. "This is a
very unique product. There isn't another product that does the
automatic 3D tracking of a person while they're doing RF
measurements."
Anritsu collaborated with TRX Systems to leverage its NEON
indoor location tracking and mapping solution and develop the
MA8100A series TRX NEON Signal Mapper. A tracker and TRX
software, used in conjunction with Anritsu's LMR Master handheld
instrument, enable lightly-trained users to be able to quickly
and accurately map signal and sensor information inside
buildings. The NEON system can be used with any of Anritsu's handheld instruments
which include spectrum analyzers, but supports some additional testing features when
used with the LMR Master that include bit-error rate, modulation fidelity/EVM and RSSI,
Wong said.
Most indoor mapping tools require the user to manually track their position by tapping a
tablet, Wong added, and those points can either be incomplete and may have
extrapolated data that doesn't accurately reflect the radio environment. Other set-ups
also often rely primarily on end-user devices rather than measurement-grade instruments
that are fully calibrated for consistent result reporting.
Data visualization is also a key component, he noted, with the accompanying software
able to quickly generate 3D coverage maps, breadcrumbs or play the test walk as a 3D
video. Cloud capabilities enable test results to be rapidly transmitted back to supervisors
who can review the data and check for gaps in coverage or additional data points that are
needed to avoid the costs associated with multiple visits.
