Survey Technologies, Incorporated was founded in 1991 to improve and automate the acquisition, analysis and display of signal strength across a given terrain. STI provided signal survey services to several major companies in 1992 and 1993, utilizing early models of the STI-9000. These activities provided an ideal test bench, pointing the way to further product improvements which were incorporated into the STI-9100 and 9150.  further improvements lead to Field Test 4 and STI Field Test 6 Software and the STI-9400 and STI-9450 mobile signal measurement and coverage analysis systems.

Recently, STI has expanded the drive-test measurement concept to include indoor measurement and analysis for applications where GPS is not available. 

Maintaining a flexible receiver interface has made it possible for customers to utilize a preferred or proprietary RF instrument for making mobile measurements.

 

The STI-9400 Laptop Signal Measurement & Analysis System!

From measurement to report, it's the most complete, cost-effective, and easy-to-use laptop signal analysis system on the market.

Now you can analyze RF signal coverage completely, get real time results, and even print your reports while in the field. The STI-9400 series systems incorporate GPS technology to fully automate drive test measurement, analysis and report of RF signal coverage across geography. Critical for New Site Setup, Proof of Performance and Ongoing System Maintenance, the 9400 quickly and cost effectively translates large amounts of signal measurement data into clear concise reports.

The STI-9450 Signal Measurement & Analysis Kit!

The STI-9450 is essentially the same GPS based signal measurement and analysis system as the 9400, only it is installed on your laptop computer. The STI-9450 includes; STI Field Test 6 software, a GPS receiver contained within mounting hardware, a magnetic mount GPS antenna and street map data for the entire USA.

STI Field Test 6 Software Only $6,500.00 with selected instrument drivers

The STI Field Test 6 software package can be configured into one of the more complete solutions above or it can be used to automate an RF instrument that you may already own.  Our newest interface is for the Aeroflex IFR-2975 radio test set and is availible through Aeroflex (part number AC25081).  STI also has a driver for the IFR COM-120 from Aeroflex.  STI offers interface/drivers for many Agilent instruments including the ESA 44XX series, and HP 85XX series spectrum analyzers.  Driver/interfaces can also be supplied for the Anritsu 2711 or 2721.  Other instruments can be utilized to make signal measurements on multiple frequencies during drive-tests or interface with mobile radios to make P-25 BER measurements, analog voice Audio Quality Tests, or simply make RSSI measurements.  Field Test 6 comes complete with a USB GPS Receiver, automated signal measurement and coverage analysis capabilities, as well as, street map data for the entire US.

Indoor Measurements

Automated signal coverage measurement and analysis is now possible for office buildings, hospitals, parking structures, shopping centers, etc.  Field Test 6 is being enhanced to conduct automated measurements indoors or any where GPS reception is unavailable.  Conduct frequency agile measurements while walking a predetermined route or at specific locations.  This automated indoor measurement process allows the user to create contour plots of signal coverage inside buildings parking structures, etc.  Click the Indoor Measurements link for more information.
