November 10, 2011. Rohde & Schwarz announced it has developed a multi-functional universal radio network analyzer that provides advanced drive testing. The R&S® TSMW drive-test scanner supports LTE formats in all current and future wireless communication bands. The R&S TSMW drive test scanner also supports GSM, WCDMA, and CDMA2000 1xRTT/1xEV-DO scanning at the same time.
In addition, several different frequency bands including Band 2, 4, 5, and 13 (Verizon Wireless); 14 (Public Safety); 17 (AT&T); 24 (LightSquared); and 25 (Sprint-Nextel) can be operated in parallel using a single R&S TSMW drive test scanner. Offering a wideband receiver, the R&S TSMW enables seamless band support ranging from 30 MHz to 6 GHz. Each signal with a bandwidth of up to 20 MHz can be scanned without limitation.
“The R&S TSMW is the only network scanner that supports LTE in all current and future bands,” explained Stefan Schindler, product manager for drive test at Rohde & Schwarz. “This capability comes at no additional costs and with no limitation in number of bands to be monitored, making it the perfect tool for future challenges, such as carrier aggregation of LTE-Advanced technology.”
The R&S TSMW universal radio network analyzer features an integrated global positioning system (GPS) that can be used for positioning, but is not required for measurement synchronization.
The analyzer features two highly-sensitive 20-MHz frontends for any input frequency from 30 MHz to 6 GHz, dual-channel pre-selection, and a software-defined architecture. The analyzer enables easy technology upgrades via software updates that can be done quickly, in the field.
