COLUMBIA, MD.—Rohde & Schwarz is now putting an emphasis for its LTE systems to enable technologies important for public safety communications. R&S gear fits within the entire public safety device and network ecosystem, including chipset R&D, UE functional testing, UE performance, UE conformance, UE Antenna Performance, UE services and repair, UE manufacturing, network deployment and network optimization.
The R&S CMW500 network emulator is one of these products, providing a simulation of the entire FirstNet network for testing of FDD 14 LTE mobile devices. Test areas covered include data performance, audio quality, video performance, device aggression, call reliability, mobility performance and behavior in environments with poor RF and IP traffic conditions.
Other R&S products that can be used for public safety are the R&S TS-LBS for testing location determination performance; the R&S CMW-PQA covers data performance, device aggression, call reliability, mobility performance and video performance; R&S TS8980 covers RF and radio resource management; the R&S TS8991 covers antenna performance over-the-air tests.
For events like natural disasters, the R&S Nestor mobile network survey software can be used to identify active base stations that can be used for critical communications and assess physical damage to the network infrastructure. There are also the portable R&S DDF007 and digital R&S DDF205 direction finder for search and rescue operations.
In addition, R&S PR100 portable receivers and the R&S HE400 antennas can be used to locate micro-transmitters and unlawful trespassers.
