As carrier aggregation begins to be deployed with two component carriers, Anritsu and Keysight Technologies both announced advances this week in the testing of three-component-carrier carrier aggregation, which offers even higher speeds.
Anritsu said it tested three-component-carrier Carrier Aggregation and achieved a stable peak-data rate, using its MD8430A/RTD LTE Simulator and a Category 9 LTE-Advanced modem from Qualcomm Technologies. Cat 9 speeds are supposed to reach up to 450 Mbps in the downlink.
Anritsu said it is about to test support of 3x CA with three FDD or TDD LTE component carriers, each one with a bandwidth up to 20 MHz.
Anritsu announced Cat 6 support in January, less than a year ago.
Meanwhile, Keysight said it also verified three-component-carrier CA end-to-end IP data throughput at 450 Mbps in the downlink and 50 Mbps uplink speeds. Keysight relied on its E7515A UXM wireless test set, and used three 20 MHz component carriers in the downlink.
–In other test and measurement news this week, Radio Access Network geoanalytics company Newfield Wireless said it completed its first deployment of an integrated RAN solution at an unnamed “top tier” mobile network operator. The solution combined Newfield’s geoanalytics platform, TrueCall, and virtual monitoring from TekComms’ GeoSoft RAN for a view of both the RAN and the core, coupled with location data.
Newfield is part of Tektronix Communications, and is in the process of being acquired by NetScout.
–Anite’s Triton test system for the LTE core won an award from Frost & Sullivan, while Rohde & Schwarz’s R&S RTE oscilloscope was named one of the 2014 Hot 100 Products by UBM Canon’s EDN.
–In addition to the carrier aggregation testing, Keysight had a couple other pieces of news this week: it began shipping a new impedance analyzer for electronics components, and its Bluetooth RF platform was chosen to outfit Sharp’s RF Classic and Low-Energy lab.
