Interference in the Radio Access Network is ubiquitous and becoming more critical as the deployment of the latest cellular standards brings increased sensitivity and subsequent degradation of network capacity and subscriber Quality of Experience.
In this white paper, we will explore the topic of interference...
You may have heard a lot about 5G already. You may know which network operators have launched or will soon be launching 5G, which services they have prioritized for their initial 5G rollout, and even which challenges they have faced.
But do you know which...
Last year was a big one for major network improvements, according to Opensignal, whose latest numbers show improving mobile video quality -- particularly for both Verizon and Sprint (!) -- while AT&T surged ahead in download speeds and won the category.
Despite the hype around...
Who are the users most likely to be early 5G adopters, and what do they expect 5G to do for them?
According to new data from RootMetrics, there is a subset of highly connected, mobile-dependent users who expect 5G to have a substantial and positive...
The Global Certification Forum and mission-critical standards and interoperability group TCCA are jointly launching a task force focused on certification for 3GPP-based mission-critical services, including push-to-talk, video and data.
The focus on cellular services delivered via mobile broadband networks is a shift for TCCA, which...
In the wake of a series of major, damaging earthquakes in Puerto Rico, Ookla Speedtest dove into its data from before and after to get a picture of how mobile users were impacted and the current status of the networks.
The fluctuations in power availability...

Defense technology company Perspecta says that its research arm, Perspecta Labs, has successfully demonstrated the use of a commercial LTE air-to-ground network for long-distance, high-bandwidth communications with aircraft at "well beyond Mach 1 speeds."
The company says it has developed a solution that will allow...
What will it take to get users who are still holding onto 3G rate plans and devices to give them up so carriers can re-farm 3G spectrum?
More compelling 4G rates plans, for one, according to new analysis by OpenSignal. The network and device performance...
The radio frequency environment in which wireless networks and devices operate is incredibly complex -- and completely invisible. But what if instead of sending out teams for drive-testing to get a snapshot of that RF environment on a given day in a given place,...
If vendors and users can prove out the deployment and business model associated with shared access to the 3.5 GHz CBRS band, the same approach could be applied to other underused spectrum. With GAA deployments in early days and priority access licenses about to...
Release 17 will introduce "NR-Light" for IoT
The Third Generation Partnership Project has put together its list of approved work for 5G New Radio features in Release 17, which is slated for completion in the second half of 2021.
What's in the cards for 5G NR?...
Telecom operator Orange Belgium is opening up a 5G Standalone network at the port of Antwerp to allow enterprises to explore the possibilities of the technology, particularly for industrial applications. Orange Belgium said that it has already demonstrated an actual data connection in the...
If vendors and users can prove out the deployment and business model associated with shared access to the 3.5 GHz CBRS band, the same approach could be applied to other underused spectrum. With GAA deployments in early days and priority access licenses about to...
Spirent Communications says that it has already closed more than 100 5G deals this year, in a reflection of just how fast the next generation of wireless technology is moving into deployment -- and that service assurance is being built-in from the earliest days.
“If...
5G introduces test challenges related to massive MIMO, mmWave frequencies, and over-the-air (OTA) test. Successfully overcoming these challenges is the only way to reach 5G commercialization before the competition.
