5G Security – Metrics of the Engaged

This past month on 03-06 March, the global industry sub-group that exists at the center of 5G security met virtually. It is known as SA3 within the 3GPP organization, and it met over a period of five days to deal with some of the most important 5G security requirements. 3GPP is a "partnership" created among all the world's major standards bodies, which over several decades has cooperatively developed and evolved by far the largest and most successful global electronic communications network. more

SpaceX and T-Mobile to Test Satellite-To-Cell Service This Year

SpaceX and T-Mobile are set to begin testing their satellite-to-cell service this year, an executive of Elon Musk's company confirmed Monday. Jonathan Hofeller, SpaceX vice president of Starlink Enterprise Sales, made the announcement during a panel at the Satellite 2023 conference in Washington, D.C. more

Hole in Space - the Mother of All Video Chats

New technology enables new art forms and artists Kit Galloway and Sherrie Rabinowitz (K&S) began working with geostationary satellite links in 1977. Their first work was an experiment in remote dance and music. Video of dancers at The Goddard Space Flight Center in Maryland and an educational television center in California was transmitted to a central control studio where a composite was formed and sent back to monitors the dancers could see. more

Using AM Radio Towers in Designing Wireless Networks

One existing resource that is often overlooked in designing wireless networks is AM radio towers. For the most part, companies deploying fixed wireless and microwave antenna have avoided these towers. This is due to the nature of AM radio, which transmits at such a low frequency that the entire tower is effectively used as the transmitting antenna. The entire tower is energized with the AM signal, and the typical AM tower sits on a base insulator that blocks the tower from being grounded.  more

Using LEOs and GEOs

Once you head away from the areas serviced by modern terrestrial cable infrastructure, the available digital communications options are somewhat limited. Some remote areas are served using High-Frequency radio systems, using radio signals that bounce off the ionosphere to provide a long-distance but limited bandwidth service. Or there are satellite-based services based on spacecraft positioned in geostationary orbital slots. more

For the First Time Wireless Carriers and Auto Makers Seek Common Ground on Wireless Standards

For the first time auto makers and wireless carriers are actually seeking common ground around the creation of the wireless new standard, writes Roger Lanctot, Associate Director in the Global Automotive Practice at Strategy Analytics. more

FCC Pushing for Free Internet Plan, Called Most Controversial Issue in December

Outgoing Federal Communications Commission Chairman Kevin Martin is pushing for action in December on a plan to offer free, pornography-free wireless Internet service to all Americans, despite objections from the wireless industry and some consumer groups. The proposal to allow a no-smut, free wireless Internet service is part of a proposal to auction off a chunk of airwaves. The winning bidder would be required to set aside a quarter of the airwaves for a free Internet service. more

What Will 2021 Have Install for the ICT Industry?

While 2021 will remain a year with lots of uncertainties, at the same time, we can say that the pandemic has not affected the information and communications technology (ICT) industry in any significant way. Yes, there has been a slowdown, for example, in the sale of smartphones. Shortages in both materials and expertise are slowing fiber deployment, and the recovery over 2021 will be slow and uncertain because of the many lockdowns and travel restrictions. more

Carriers Constrain Entrepreneurs

Previously, I've written about how the success of the MVNO (though not without its problems) demonstrates how an Open Access-like business model can work in a wireless context. The underlying carrier, such as Sprint or Verizon, can sell access to its network at wholesale rates to a company like Virgin Mobile, which then markets to consumers. This model can be and is a success both for the retailer and the wholesaler. MVNOs are not perfect. more

Kyiv Independent Reports on Starlink in Ukraine

"Saint Elon" is a bit much but ... It started with a tweet from Ukraine's Minister of Digital Transformation. The quoted text below is excerpts from How Elon Musk's Starlink satellite internet keeps Ukraine online in The Kyiv Independent. "Among the Ukrainian military, Elon Musk, the richest tech entrepreneur in the U.S., is often half-jokingly referred to as 'Saint Elon.'. The reason is Starlink, Musk's satellite communication system that keeps many Ukrainians, most importantly the military... more

Starlink’s zoomready Rating Is Going Down

zoomready is open-source shareware I wrote to measure the suitability of an internet connection for teleconferencing. As you can see above, Starlink had an average zoomready rating of 2.66 out of a possible 3.0 over the four measured days. The problem is NOT bandwidth, which has fluctuated but stayed above the minimums needed for good teleconferencing. The problems are failures (most of them short), latency, and jitter. more

6G Collaboration by U.S. and Allies Against Authoritarian Control

The United States, along with key global partners, has formally committed to principles guiding the development of 6G technology, as announced by the White House. This move comes amidst a strategic contest to shape the future of wireless communication standards, driven by concerns over authoritarian regimes exerting greater control over the internet within their borders. more

Almost All 5G Estimates for 2019-2020 Need to Be Doubled

The remarkable take rate in Korea and China is invalidating almost all projections of 5G subscriptions. The 5G promotion has consumers wanting to buy, buy, buy. Huawei Mate 20 5G is selling for only US$30 more than the 4G model. At that price, who would want to buy a 4G phone that could be obsolete in a year or two? In the first two weeks of sale, over a million Chinese bought Huawei's 5G phone. more

Satellites Directly to Cellphones

AT&T and satellite company AST SpaceMobile announced a partnership to provide satellite cellular service directly from satellites to cellphones. This will provide a service that is much needed for the billions of remote users who are not in the range of a cell tower. This is an emerging industry that is still being referred to by different acronyms. more

In the 5G Era, at Least 20 Million U.S. Homes Will Rely on Wireless for Broadband

There now can be no doubt that fixed wireless, mostly 5G, will be a viable business in the right locations. Today's wireless has enormous capacity, enough to supply the broadband needs of a significant population. It's better than most DSL and a workable alternative to cable in many locations. Traffic demand is falling, with Cisco predicting the U.S. will fall to 31% growth in 2021. more
