Sam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his November newsletter that features his short op−ed entitled "Do You Think 5G is Challenging? Meet 6G!," which delves into what can be expected based on current planning. "Like its predecessor, 6G is more than simply an upgrade in data rates and capacity, as it will attempt to deliver downstream data rates up to 1 Tbye/s and operate at frequencies in the so-called sub terahertz region, just below where lightwave frequencies begin. It will make extensive use of artificial intelligence and machine learning to enable applications that 5G presumably will not have been addressed in the next decade." . Also included in the newsletter are a few industry headlines.

Even though 5G is just now beginning to demonstrate its capabilities, researchers throughout the world are already concentrating on 6G, which according to most reports should be deployed around 2030. Like its predecessor, 6G is more than simply an upgrade in data rates and capacity, as it will attempt to deliver downstream data rates up to 1 Tbye/s and operate at frequencies in the so-called sub terahertz region, just below where lightwave frequencies begin. It will make extensive use of artificial intelligence and machine learning to enable applications that 5G presumably will not have been addressed in the next decade.

If all this sounds like fantasy, consider that 5G sounded about the same when it was revealed that frequencies well into the middle millimeter-wave region would be used for the first time, data rates would be greater than 1 Gb/s, and round-trip latency would be reduced to a few milliseconds.

Now it appears that most of these promises may be kept, but probably not everywhere, as the highest data rates will only be achievable at the highest frequencies where the most bandwidth is available. These are also the regions of the spectrum where range is very short and attenuation through space can be impeded by almost anything, from precipitation to foliage, and of course buildings.

There are immense challenges that must be overcome before 6G can become a reality, from development of semiconductor technologies able to produce measurable power at sub-terahertz frequencies, to the electronically-steered, phase-array antennas required to deliver enough gain to overcome the various factors that make communication extremely difficult in this spectral region.

Will these requirements even be possible? I think they will, because there is much to gained, well beyond downloading a Netflix in 2 seconds. From extremely precise location and other sensing applications to anti-jam communications where short-range is actually desirable, and dozens more.

By 2030, it's likely that huge advances in software-defined hardware, AI, computing power, and other technologies will have taken place. Networks will evolve from purely terrestrial wireless to encompassing satellites that fill in the gaps where earth-bound platforms cannot reach, and a long list of other accomplishments. Time will tell, but I'm optimistic.

Nokia, Elisa, and Qualcomm have achieved the world's fastest 5G speeds on a commercial network in Finland, delivering speed up to 8 Gb/s. The record was achieved by serving two Qualcomm 5G millimeter-wave devices connected simultaneously to Elisa's network, which is powered by Nokia 5G equipment. To complete the record-breaking attempt, the team used a base station using two Nokia AirScale radios, each using 800 MHz of millimeter-wave spectrum at 26 GHz. This provided connectivity to two Qualcomm devices with Snapdragon X55 5G SoCs with each device reaching 4 Gbps peak speeds from the base station.

The world-famous Arecibo Observatory in Puerto Rico, known for helping scientists peer into deep space and listen for distant radio waves, is set to be decommissioned and demolished after engineers concluded that the facility's structure is at risk of a collapse. While teams will try to salvage some parts of the observatory, the decommission will bring an end to the popular 57-year-old telescope. The decision comes after two major cables failed at the facility in last few months, causing significant damage to the observatory. The National Science Foundation (NSF), which oversees Arecibo, determined that the facility's other cables could also soon fail. If they did, the entire 900-ton suspended platform could come crashing down on Arecibo's 1,000-foot-wide dish. NSF hopes to continue work at the Arecibo Observatory LIDAR facility and continue operating an offsite facility on the island of Culebra that collects data on clouds and rainfall

An advisory panel to the Health Council of the Netherlands is recommending a “cautious approach” to 5G radiation exposures. The committee is also advising that the 26 GHz frequency band not be used “for as long as the potential health risks have not been investigated.” While the panel endorses recently revised guidelines on the matter it notes that exposure under has the potential to affect health. The full 800-page report illustrates the concerns and considers that studies on human health at millimeter-wave frequencies has not been studied as thoroughly as those currently used by wireless services at 6 GHz and below.

The UK's Tempest sixth-generation fighter aircraft under development for the Royal Air Force (RAF) will have reconfigurable artificial intelligence and cyber-hardened communications that allow it to act as a flying command and control center, where the pilot acts more as an executive officer than a dogfighter. A new radar system being developed by Leonardo UK called the Multi-Function Radio Frequency System is claimed to be able to handle 10,000 times more data than existing systems, processing as much data per second as the entire Internet traffic of a city the size of Edinburgh.
