RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Anatech Electronics Header: November 2020 Newsletter

 

Sam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his December newsletter that features his short op−ed entitled "2020: The Year that Was… ," in which Sam assess how he well did in predicting various key industry trends at the end of last year. You can read his piece to see how he scored, but I do want to note a specific point. One of Sam's predictions pertained to the availability of broadband service in rural areas. The Wuhan Flu epidemic that caused most schools to implement a remote classroom environment exposed how deficient the system still is, even though we thought the issue had been pretty much resolved (goodness knows we've spent enough tax money to address it). Also included in the newsletter are a few pertinent industry headlines. Stand by for Sam's end-of-year predictions for 2021...

A Word from Sam Benzacar

2020: The Year that Was…

Anatech Electronics December 2020 Newsletter (Sam Benzacar) - RF CafeBy Sam Benzacar

By any yardstick, 2020 has been a year like no other in memory, and from a health perspective, one that with luck will not be repeated. As has been my custom, last year in this newsletter I attempted to predict how the RF and microwave would fare in the coming year in several key markets. So, let's see how I did.

5G and Mid-Band Spectrum

Deployment of the fifth-generation standard continued, with T-Mobile having the advantage of more low-and mid-band spectrum (at 600 MHz, for example) than AT&T or Verizon. As for fixed wireless access: It's available in a few cities but is not yet the "true cable competitor" I said it would be. By this time next year 5G should be available more widely and every new phone will include at least some 5G bands. Full deployment will take at least another 2 years and very low latency and very, very high speed will take even longer.

IoT

The IoT umbrella is wide and deep and large-scale deployment is limited to those large companies that can afford to deploy it, and they are doing so, warily. I assumed some technological hurdles would be overcome, and some have been, although more many more remain. As "Industry 4.0" becomes more than a name, smaller companies will take the plunge. AI will be the technology to watch next year because it's the key ingredient for providing actionable information to end users.

Rural Broadband

Even after billions of dollars of government incentives, broadband is still unavailable or unaffordable for many people. This sad fact was driven home this year by the immense number of families whose children still cannot use virtual learning for lack of Internet access and had to use a public hotspot. The visibility of this shortcoming gave the telecom industry and the FCC black eyes so next year should be better, but still not enough.

Defense

I predicted, accurately, that the RF and microwave industry would benefit from DoD's efforts to upgrade EW, radar, and signals intelligence across the board. Next year promises more of the same as new budget provides for it, and threats from adversaries are becoming more sophisticated.

2021 in a Nutshell

I expect next year to be lucrative for RF and microwave manufacturers because there are arguably more commercial and defense opportunities than ever. In short, I'm optimistic.

 

With that, have a great, safe holiday from all of us at Anatech Electronics!

 


FCC Slices off DSRC Spectrum for Wi-Fi - RF CafeFCC Slices off DSRC Spectrum for Wi-Fi

Dedicated Short-Range Communication (DSRC) that the FCC created in 1999 for “intelligent” automotive use has been reduced from its original 75 MHz at 5.9 GHz to 45 MHz, the rest to be used for Wi-Fi. Two factors dr0ve this decision: the reality that cellular technology will be used instead of the original technology for cellular “vehicle to everything” communications, and the wireless industry's desperate need for even tiny slices of mid-band spectrum. The move essentially puts paid to the discussion about whether DSRC or cellular would reign in the world of autonomous vehicles.

 


Amazon Streams 4K Video from Satellite - RF CafeAmazon Streams 4K Video from Satellite

Amazon passed a milestone in developing the hardware needed for its planned Project Kuiper internet network. The company plans to launch 3,236 satellites into low Earth orbit to provide global broadband service, competing SpaceX's Starlink network. The team completed initial development of the antenna (shown below) that will be housed in its "low-cost customer terminal," which will connect users to Amazon's network. Amazon said it has been field testing the Kuiper antenna in multiple environments including streaming 4K-quality video from a geostationary (satellite).

 


 

58% of Base Station to Use O-RAN by 2026 - RF CafeReport: 58% of Base Station to Use O-RAN by 2026

Open RAN will account for 58% of total RAN spending at $32.3 billion and will be deployed at 65% of all sites by 2026, according to the "Open RAN adoption patterns and forecast 2020-2026" report by Rethink Technology Research. The report says Open RAN deployments will occur rapidly, especially in small cell environments, rather than in macro and micro-RANs.

 


 

Dutch Panel Cautions on Millimeter-Wave 5G - RF CafeDutch Panel Cautions on Millimeter-Wave 5G

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 band not be used “for as long as the potential health risks have not been investigated.” Because the lower frequency bands for 5G up to 3.5 GHz have already been used for years without resulting any proven adverse health effects, the committee sees no reason to stop or restrict their use. It recommends that the exposure should be monitored before, during and after the rollout of the 5G systems. This will make clear to what extent exposure to RF fields changes as a result of the introduction of 5G and any long-term health risks can then be estimated better. The WHO analysis can also be used in estimating the risks.

 


Defense Agencies to Spend $1.3 Billion by 2025 - RF CafeStudy: Defense Agencies to Spend $1.3 Billion by 2025

The global market for 5G in defense, $64 million in 2020, will grow to $1.3 billion with an annual growth rate of 57.9%, according to a new study from MarketsandMarkets, "5G in Defense Market -- Global Forecast to 2025." Factors in the huge increase will include higher network speeds, lower latency, and the growing adoption of autonomous and connected devices. The airborne segment is projected to see the highest growth during the period because of 5G technology advances, airborne applications including unmanned aerial systems (UASs), and the increased need for mission-critical communications.
