The MDT solution taps user equipment (UE) to collect field measurements Introduced in 3GPP Rel-10, Minimization of Drive Test (MDT) is a standardized mechanism designed to enable operators to use user devices in a network to collect mobile network data, and thus, reduce the need...

As network operators navigate a multi-pronged transformation that encompasses 5G, fiber proliferation, increasingly cloud-based and virtualized networks, one of the challenges that they face is that of radio frequency interference. RF interference is not a new issue in wireless networks, and in fact, some of...

Verizon and Oracle hope to spur new 5G innovation at the Oracle Industry Lab, now equipped with Verizon's 5G mmWave service.

There has been a long-running debate in network testing that basically asks, which is better: Highly controlled and repeatable drive- and walk-testing with special test set-ups to get deep RF and chip-level data, which shows what a network is capable of with the latest...

Ookla, known for its Speedtest product, is adding to its portfolio of network data with the acquisition of drive- and walk-testing specialist RootMetrics. Financial terms of the deal were not disclosed; RootMetrics has been part of IHS Markit. “Ookla plus RootMetrics fully enables the...

There are two pillars that support the 5G user experience: Availability and performance. According to a new report from Rootmetrics, T-Mobile US is leading in 5G availability across US cities, but AT&T's 5G provides the best performance and AT&T and Verizon both win high...

The most-populous market in the U.S. -- New York City and its surrounds -- is also the fastest, according to a new ranking of metropolitan cellular networks by Rootmetrics. New York City’s aggregate median download speed of 46.3 Mbps was the fastest in the country,...

Speed, speed and more speed: So much of the consumer expectations, and industry testing and bragging, are focused on the new heights of speed that 5G can achieve. The question of which operator has the fastest 5G network is one which has recently been...

In a mmWave world, turning a corner or spinning in your desk chair might very well mean your device losing the signal. While high frequencies have been used for point-to-point network backhaul links, cellular carriers have never before made common use of these frequencies...

Dr. Paul Carter is CEO of network benchmarking and analysis company GWS. RCR Wireless News recently reached out to GWS to discuss testing millimeter-wave 5G networks. The following Q&A was conducted via email and has been lightly edited.  How is benchmark testing different in mmWave,...

U.S. wireline networks held up well overall under the network usage shifts associated with the coronavirus pandemic, according to new data from benchmarking and analysis company umlaut provided exclusively to RCR Wireless News. The one exception seems to be related to ultra-high-definition streaming, which...

In RootMetrics' first round of benchmarking that used 5G-enabled devices to test both 4G and 5G networks, Verizon and AT&T ran neck-and-neck in most categories. But Verizon ultimately topped the rankings in most performance metrics, although AT&T outpaced Verizon in terms of speed. RootMetrics temporarily...

Carriers' network investments are paying off with higher customer satisfaction Global Wireless Solutions has crowned AT&T the "best network" in its third annual national testing, but all of the three national operators can find good news in GWS' latest network scoring, which couples nationwide drive-testing...

T-Mobile US has asked the California Public Utilities Board to modify some of its conditions on approval of T-Mo's acquisition of Sprint, zeroing in on the 5G deployment timeline, jobs within the state, and how the combined carriers' network will be tested. The CPUC issued...

Verizon's network has provided it a consistent advantage over its competitors over the years. The differences are narrowing, according to data from RootMetrics, but the carrier still shows "consistent and excellent performance across the board" and has been stepping up its network speeds in...

Keysight says it has supported the development of about 75% of 5G devices Pandemic notwithstanding, the march toward 5G is so far continuing at a rapid clip across the industry, with new networks launched since the beginning of the year, a surge of available devices...

  Chief among the many shockwaves stemming from the COVID-19 outbreak in the U.S. is the country’s rapid transition to remote work. And with this disruption has come a dramatic transformation in the volume of wireless network traffic and in consumer connectivity habits and behavior:...
