The St. Louis, Missouri market is a hotly contested one, according to RootMetrics’ most recent analysis: AT&T, Verizon and T-Mobile US networks’ all do well in different aspects of performance, the benchmarking company said.

While T-Mobile US has a history of good data performance in the market and won that test segment outright again, AT&T and Verizon had the fastest median download speeds at 42.0 Mbps and 41.6 Mbps, respectively. Verizon had the fastest median upload speed in the market: 15.8 Mbps. All three carriers shared the top rating in text message performance, and Verizon and AT&T shared the top spot for call performance.

RootMetrics also recently assessed its data from the San Antonio, Texas and highlighted Verizon’s top performance in the market, while noting that both T-Mobile US and AT&T have made improvements and that data performance is a clear priority for all four carriers in the San Antonio market.

RCR Wireless News’ Sean Kinney talked with Spirent Communications at Mobile World Congress Americas about automating service assurance for 5G. Read that story here. Spirent recently said that it is supporting a major push for automation among network operators in the U.S. and Mexico.

Spirent also has announced that its Landslide emulation solution will be deployed at the University of Surrey’s 5G Innovation Centre, both for validating new 5G algorithms and for generating traffic in line with that of large mobile networks, for the testbed that covers about four square kilometers of indoor and outdoor environments at the university campus.

Amdocs has integrated EXFO’s active service assurance solution into its Amdocs NFV powered by Open Network Automation Platform, or ONAP, in an offering that is aimed at providing real-time active testing and monitoring and a “foundation for fully autonomous service assurance,” according to the test company. EXFO is an Amdocs Open Networks partner and said that its solution is fully ONAP on-boarded and certified.

“Virtualized networks and services challenge the carrier’s ability to manage end-to-end service quality since they are continuously changing,” said Abdelkrim Benamar, EXFO’s VP for service assurance, systems and services, in a statement.  “Embedding active service assurance in the service chain and making it an integral part of the service definition, gives service providers the ability to automate the entire service lifecycle and drive autonomous network and service optimization–-unleashing the true benefits of virtualization.”

Ixia was part of what it says was the first demonstration of 400G interoperability that included live Ethernet traffic. The demo was conducted over InnoLight Technology’s OSFP optical transceivers, while Ixia’s AreaOne-400GE test system provided 3.2 terabytes per second of Ethernet test traffic.

Rohde & Schwarz said that its CMW test platform now supports over-the-air testing for Bluetooth Low Energy signaling, as well as conducted measurements. The company noted that since many BLE devices “offer no port or interface to connect to a control line but nevertheless need to be tested under realistic conditions,” the new OTA option offers a feasible testing option for production or chamber-based testing.

Rohde also said this week that it has added GPS L5 and Galileo E5 simulation capabilities to its R&S SMW200A — which it notes is the first and only vector signal generator that can be turned into a navigation signal generator and generate complex coexistence and interference scenarios with multiple interferers.

The test company also recently hosted a five-day International Telecommunications Union Academy workshop on implementing radio monitoring systems.

GL Communications has added support for GPRS Tunneling Protocol traffic simulation to its PacketCheck PC-based Ethernet tester.
