Anritsu, TRX Systems partner to deliver easy-to-use RF signal-mapping solution for indoor environments

With such time savings, it is more practical for government entities with in-building coverage coverage requirements to regularly get updated input from facilities owners, as well as verification from government inspectors, Wong said.

“This can be used by the agencies or any of the contractors that do the work for these agencies or the building owners,” he said. “This lets them do the [RF-coverage] mapping of their buildings to satisfy the safety codes. Then, they can send in a report that says, ‘I’ve measured this building, and it meets the minimum requirements for in-building coverage.

“From inception to certification, this tool can be used for in-building mapping.”

Depending on the number of sensors and the type of measuring equipment used, the Anritsu-TRX Systems solution could measure the RF coverage from multiple technologies in myriad spectrum bands, according to Wong.

“You could set it up for 10 different bands, and it could go sequentially through every one of the bands every second or two. That means, with every step, you’re going to get a measurement of 10 different bands,” Wong said. “So, if a user wants to look at LTE, GSM, Wi-Fi, Bluetooth or just the different police and fire band, you just set up the scanner to scan those bands and just walk.

“If the scanner is a little slower, then you walk at a slower pace or you walk the building two or three times.”

This works even better if it is done in a building that provides Wi-Fi access, because then the command-station software can track the tester in real time, Wong said.

“So, you could have a command center send people out to do mapping, and they can see where you are in real time, because the sensor relays its information through Bluetooth to your Android device,” he said. “If it’s connected to the Internet—though [cellular] wireless or Wi-Fi—that position information is sent in real time to the command-center software that can track it. Then, the tracking can be done on multiple devices.”
