Wireless Internet

It's been long known that trees can slow down some 5G signals. 5G has the potential to supercharge wireless networks, but its rollout has revealed a range of complex challenges.

AT&T and Verizon agreed to delay their rollout of a new 5G service for two weeks, after the Federal Aviation Administration requested they do so in an effort to mitigate potential interference with airplane safety systems. At Transportation Secretary Pete Buttigieg’s request, “we have voluntarily agreed to one additional two-week delay,” an AT&T spokesperson said.

The US Court of Appeals for the District of Columbia Circuit ruled in favor of the Federal Communications Commission in its decision to designate a large swath of the 6 GHz band to unlicensed users, including Wi-Fi. AT&T had challenged the FCC’s decision, saying it posed potential interference with existing fixed microwave users. “Petitioners have failed to provide a basis for questioning the Commission’s conclusion that the Order will protect against a significant risk of harmful interference,” the court wrote in its December 28 decision.

Cellular networks can sometimes play an outsized role in disasters because they can often function on backup power sources like generators. Meaning, when nothing else is working, cell phones can connect calls. But the nation's biggest wireless providers – as well as a variety of other entities – are pushing against suggestions that the federal government mandate the use of backup power generators at all cell sites. In general, the US wireless industry has rejected increased federal oversight over providers' operations.

Ookla examined Speedtest Intelligence data from Q3 2021 Speedtest results to see how 5G speeds have changed, where download speeds are the fastest at the country and capital level, where 5G deployments have increased, and what worldwide 5G Availability looked like in Q3 2021. Over the past year from Q3 2020 to Q3 2021, the median global 5G download speed fell to 166.13 Mbps, down from 206.22 Mbps in Q3 2020. Median upload speed over 5G also slowed to 21.08 Mbps (from 29.52 Mbps) during the same period.

The City of Amarillo (TX) plans to use American Rescue Plan Act (ARPA) funding to build a fixed wireless network targeting low-income households. “We will lead with that technology; it doesn’t mean we won’t have to change moving down the road [or] where we can’t do line-of-sight,” said Rich Gagnon, the city's managing director and chief information officer. A particular concern in Amarillo was the large number of refugees – 12,000 – who have settled in the city, many of whom do not have broadband available to them.

The Federal Communications Commission is considering putting new restrictions on wireless use of C-Band spectrum, including a nationwide power reduction, as the Biden Administration works on how best to free up that spectrum for 5G without risking interference to critical aviation communications. Wireless deployments in the band were delayed from fall 2021 given concerns by the Federal Aviation Administration (FAA), but are now scheduled to launch January 5, 2022.

Internet service provider EarthLink has joined a growing number of companies offering fixed wireless service. The company’s offering, dubbed EarthLink Wireless Home Internet, uses LTE or 5G for connectivity to the internet and can support up to 64 devices, in comparison with 10 devices for a mobile hotspot. A typical household has 11 connected devices, EarthLink notes on its website.

T-Mobile plans to make its Ultra Capacity 5G service available to 100 million more Americans in 2022, and as the company’s President of Technology Neville Ray told investors, it will have to expand its geographic coverage five-fold to achieve that goal, reaching many rural areas. Ultra Capacity 5G is the name that T-Mobile uses for 5G deployed in mid-band spectrum, which is widely viewed as supporting the optimum mixture of range and speed.

The internet has become necessary infrastructure during the pandemic, but ubiquitous 5G service has been slow to fully develop in the US. Sidewalk Infrastructure Partners (SIP) said it will invest $100 million to both acquire wireless infrastructure company Dense Air and use its small cell technology to build a "borderless classroom." SIP, which was spun out of Google-parent Alphabet, intends to work with an as-yet unnamed city to build a private wireless network for a school district so students can connect to the same network whether they're in the classroom, on the school bus or at home,
