The bigger picture: The Trump administration has already blocked Chinese telecom equipment maker Huawei from selling to American companies on national security grounds, driven largely by fears that China could use 5G network equipment to spy on Americans.

• China is seen as the country to beat in deploying next-generation wireless infrastructure. Last week the FCC unveiled efforts to give the U.S. a leg up in the 5G race against China.

Details: China Mobile's application, submitted in 2011, requested permission to provide telecom services in the U.S., including connecting calls between the U.S. and the vast majority of countries, which would involve interconnecting with American internet networks.

• FCC officials say China Mobile USA is indirectly and ultimately owned and controlled by the Chinese government. It's a subsidiary of global telecom giant China Mobile Limited.
• U.S. officials saw risks that China Mobile would comply with government espionage requests or that information about U.S. communications networks and users could be exploited. There were also concerns that Chinese government officials could use its access to U.S. networks to block or interfere with communications traffic should an issue arise between the two countries.
• After consultation with the intelligence community, executive branch agencies concluded those risks couldn't be resolved through a voluntary mitigation agreement.
• Mitigation agreements require a baseline level of trust between parties, which does not exist in this case, per an FCC official.

What's next: The full commission will vote on Pai's recommendation at its May 9 meeting.

• While the impact of technology on kids is still relatively unknown due to a lack of long-term research, researchers attribute more screen time to increased demands on parents and the convenience of always-on smartphones and tablets.

The big picture: Every generation is drawn to the latest type of media, from gathering around the radio to spending hours in front of the TV. Today's technology — the gestural nature of touch screens, for example — is more intuitive for the preschool set and is used for educational purposes, too.

• That makes it even harder for parents to figure out where to draw the line on screen time, especially when parents often find themselves glued to their own screens to keep up with busy lives.

Not all screen time is created equal, as experts have pointed out that some educational programming, interactive features and personalized content can be beneficial for kids.

• But mediating what children are exposed to across platforms is getting more challenging with the ever-increasing amount of kid-targeted content and algorithms pushing out the next piece of content that can feel out of parents' control, said Shelley Pasnik, director of the nonprofit Center for Children and Technology.
• "The curatorial lift for parents is not insignificant, it requires thought and time to make those selections," she said. "That can feel daunting, along with the fear of missing out and the fear of choosing well for their kids. There's no shortage of opportunities for parents to feel bad."

Adding to those fears are reports about the dangers of exposing children to user-generated videos online.

• A new Wall Street Journal report finds that many of the most popular YouTube playtime videos are often made by unidentifiable sources, and some of them with seemingly Russian ties.
• Apps like YouTube Kids and Facebook's Messenger Kids have increased parental controls and content monitoring. But parents still worry about unexpected and questionable content popping up without their knowledge.

Streaming TV plays a role in this too. A recent Reuters piece describes the onslaught of streaming services targeted toward kids as part of the problem. "Children are the original binge-watchers, with an endless appetite for repeats," it notes.

The catch: Parents may not feel like they have better options to safely entertain children at home or on the go. This is particularly true of parents trying to juggle work and child care, or those balancing multiple jobs.

• A study published in the Journal of the American Medical Association this year found that an increase in screen time for kids might not be the result of new technologies, but rather caused by changes in parental interactions because of work schedules or other socio-economic factors.
• The study notes that the 2014 high screen-user group was dominated by boys and children with low parental education levels and family income.

Baby boomers and Gen Xers often reminisce about the days of meeting up with friends at the neighborhood cul-de-sac or mall. But today, many parents are less comfortable sending their children outside to play unattended.

• A recent UK study found children spend half the time playing outside than their parents did when they were kids.
• The economic realities of most dual-career households reduces the availability of adult supervision for activities outside the home.
• The reality is that phones, tablets, computers and TVs have become some of the easiest ways to keep kids settled and out of trouble.

The bottom line: While screen time is unavoidable for most modern families, how parents involve themselves in the experience can change the equation for kids, Pasnik said.

• "Parents talk to their babysitters, kids talk to their babysitters," she said. "Even with digital tools, we can say to our kids, 'Hey, what was that like?' That conversation can continue — just as we continue the conversation with the people who care for our kids."
