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

Is the Defense Innovation Unit’s Hybrid Space Architecture the “ARPANET” of Space and Will It Run on Aalyria Spacetime?

The goal of the Defense Innovation Unit (DIU) of the Department of Defense is to strengthen our national security by accelerating the adoption of commercial technology throughout the military and strengthening our allied and national security innovation bases. Space is one of its areas of focus and two of the space "lines of effort" are multi-orbit operations and logistics and hardware-to-software transformation modernization. more

Rural America is Losing Patience

From all across the country, I'm hearing that communities without broadband are tired of waiting for a broadband solution. Local broadband advocates and politicians tell me that folks with little or no broadband are hounding them about when they are going to see a broadband solution. A large part of the frustration is that folks have heard that broadband is coming to rural America but aren't seeing any local progress or improvement. more

Pinpointing Urban Broadband Gaps

The City of Chicago asked some researchers at the University of Chicago for help to identify the neighborhoods and the number of households that are not connected to broadband. It's been well known that large numbers of people in cities don't have broadband, but there have been no easy ways to pinpoint where solutions are needed. more

Broadband Satellite Issues

One of the most interesting aspects of serving broadband from low-orbit satellites is that it brings issues related to space into broadband discussion. Space issues were less important for high earth orbit satellites that sit 20,000 miles above the earth. Other than an occasional impact from sunspots, there wasn't much of note. But there are two recent events that highlight our new focus on low-earth orbit satellites. more

Google Fiber to Push Speed Limits Again

Dinni Jain, the CEO of Google Fiber, posted a blog last week that talks about dramatically increasing the top speeds available on fiber. He says the specific announcement will come in the coming months to dramatically expand Google Fiber's gigabit offerings. The blog gives a hint at what might be coming. Included in the blog is a speed test from the home of a Google Fiber employee in Kansas City who is receiving 20.2 Gbps. more

Aalyria, a Space Internet Startup With Nearly a Decade’s Worth of Intellectual Property From Alphabet

Aalyria, a new space Internet company, just burst out of stealth mode. It is based on work done on Alphabet's "moonshot" Project Loon and Alphabet transferred almost a decade's worth of technology IP, patents, office space, and other assets to Aalyria in return for an equity stake in the company. Spacetime is Aalyria's intelligent network orchestration technology, and Tightbeam is its advanced atmospheric laser communications technology. more

Broadband Deserts

Perhaps it's because the death of Queen Elizabeth has been everywhere in the news, but somebody sent me an article from the BBC from 2008 where then Prince Charles warned that the lack of rural broadband in the UK was going to eventually result in broadband deserts. The now King Charles III was quoted as saying that lack of broadband puts too much pressure on the people who live without broadband and that if a solution wasn't found... more

The Data Divide

A report from the Center for Data Innovation warns of a new broadband gap they call the data divide, which is when some parts of society are not sharing in the big societal advantages that come from using and understanding the huge amounts of data that are being generated today. The report includes examples of the data divide that make the concept easier to understand. more

The 12 GHz Battle

A big piece of what the FCC does is to weigh competing claims to use spectrum. It seems like there have been non-stop industry fights over the last decade on who gets to use various bands of spectrum. One of the latest fights, which is the continuation of a battle going on since 2018, is for the use of the 12 GHz spectrum. The big wrestling match is between Starlink's desire to use the spectrum to communicate with its low-orbit satellites and cellular carriers and WISPs... more

Satellite Cell Service: What’s Coming

T-Mobile and Starlink made a joint announcement recently about an arrangement where Starlink will enable voice and texting capabilities to T-Mobile cellphones by the end of 2023. This is a service that would work with existing cell phones and would supposedly kick in when a phone can't find a signal from a cell tower. Starlink said the technology would be enabled by new satellites that have significantly larger antennae than the current satellites in the constellation. more

Cable Companies Tout Speed Increases

Last month, NCTA -- The Internet and Television Association -- posted an article on its website touting the big increases in broadband speeds since the start of the pandemic. NCTA is the industry trade and lobbying association for medium-sized and large cable companies. The article touts that the average U.S. download speed has grown from 138 Mbps in March 2020, the first month of the pandemic, to 226 Mbps in June 2022. more

From “Network Neutrality” to “Sender Pays”, the Principles Remain Much the Same

The entire set of issues of network neutrality, interconnection and settlements, termination monopolies, cost allocation and infrastructure investment economics is back with us again. This time it's not under the banner of "Network Neutrality" but under a more directly confronting title of "Sender Pays." The principle is much the same: network providers want to charge both their customers and the content providers to carry content to users. more

SpaceX Introduces Affordability-Based Starlink Pricing

When SpaceX announced the price of the Starlink service, Elon Musk said it would be the same everywhere but I wrote that eventually it would be priced to be affordable in different nations. (If you predict enough things, you are bound to get something right). The fixed cost of a satellite Internet constellation is high -- satellites are expensive to make and launch -- but the cost of adding and servicing a new customer is low, and the market is global. more

The Birth of the Digital Divide

A lot of the money being spent on broadband infrastructure today is trying to solve the digital divide, which I define as a technology gap where good broadband is available in some places but not everywhere. The technology divide can be as large as an entire county that doesn't have broadband or as small as a pocket of homes or apartment buildings in cities that got bypassed. more
