Spectrum Manager Application Guide
Two-Way & SMR - Two-way service providers and SMR operators will
find Spectrum Manager useful for logging repeater usage, licensing and coordination
(see below), interference reduction and identification of unauthorized users.
can be set up to provide logging, alarms, external device control and tape recording based
upon frequency and PL/DPL tones. Since can support the concurrent control of up
to ten receivers, large systems can be monitored. The Digital Audio Logger can be used to
help track down unauthorized users.
Site & Network Management - can solve some of the unique
problems of site management. Using modems and remote access software such as PC-Anywhere
or Carbon Copy, monitoring equipment can be placed at remote sites and controlled from a
central location. The Digital Audio Logger can be used to record audio for later
transmission, or DSVD modems can be used to provide simultaneous audio and digital
Law Enforcement, Surveillance and Countermeasures - s
monitoring tools are useful for intelligence gathering, dispatch overview, intersystem
coordination, surveillance and emergency management (see below.) The Spectrum Analyzer and
Band Scope tools are particularly useful in countermeasures work. The Digital Audio Logger
can be used for unattended audio recording.
Emergency Management - Effective management of radio resources during
large scale emergencies is a critical need. This task is difficult because of the variety
of different (and often incompatible) radio systems in use. Spectrum
Manager is a
powerful tool that gives on-scene managers instant access to radio intelligence, and the
ability to quickly adapt to local requirements. By using preset frequency lists and the tactical display, emergency coordinators can get instant visual and audio
information on the tactical situation. In addition, the monitoring environment can be
quickly tailored to the nature of the event with point and click channel controls. Each
channel has a text name, so memorization of frequencies is unnecessary.
Two-Way System Engineering - The Traffic Analyzer is
designed to provide an easy method of recording system loading data. All statistics are
aggregated by hour, and include Erlang, call count, air time and average signal strength.
In addition, raw measurements can be recorded directly to disk, and augmented with GPS
position and time if necessary.
Licensing and Coordination - Traditionally, locating frequencies for
re-use has been expensive, time consuming and often unreliable.
Spectrum Manager makes
this task easy by automating the process. Because it uses sampling techniques, a
significant number of channels can be examined with a single radio. Accuracy of the data
is assured, even when some or all of the channels are heavily used. In contrast,
conventional techniques require a radio dedicated to each channel to prevent loss of
accuracy. Since records data in standard DBASE format, its easy to
integrate usage statistics into reports, proposals and even other business software. also includes the ability to directly access FCC license databases, such as the Percon Regional CD ROM.
Wireless - Low power, unlicensed (part 15) technologies are increasing
the demand for "quiet" spots in the spectrum. Many new systems, such as
Spectrum Manager equipment monitors, irrigation controls, alarm systems, wireless telemetry and
remote controls share frequencies that can have high powered users.
offers a convenient, portable and inexpensive method of finding usable channels prior to
installation. Later on, if interference is suspected or observed, can track it
down and identify alternate channels to use.
Interference Resolution - Intermod interference is always a difficult
problem to solve. Often, the hardest part is determining which transmitters are causing
the problem. The Interference Correlator uses a coincident event correlation
technique to identify the unknown signals quickly.
Broadcast System Engineering - provides a low cost tool that
can be used to gather field strength information for a number of stations for comparative
studies. The GPS option makes "drive around" studies simple and economical.
Cable TV - A common problem in cable TV systems is interference caused
by the entry of unwanted signals into the transmission system. The Interference Correlator can be used to identify the frequency of signals causing interference.
Paging - Paging system operators will find an valuable tool
for monitoring channel air time, competitive studies and investigating coverage problems.
The GPS option can be used to record measurements on the road.
Cellular & PCS - offers a low cost alternative method of
gathering channel use and coverage data that is independent of network infrastructure. The
Traffic Analyzer has the unique ability to measure signal strength from several sites at
the same time, and to tag measurements with GPS derived time and position.
TV, Radio and Print News Media - The news media makes extensive use of
radio technology to catch emerging stories, report on traffic conditions and coordinate
field activities. The Conventional Scanning Tool and Tactical Display are well
suited to news desk use. The ability to rapidly focus scanning activity allows
non-technical users to tailor the listening environment to a specific incident without
memorizing frequencies or having to look up channels in a book, just by clicking the
mouse. Frequency lists can be prepared in advance by technical personnel.
