It's common to hear that oversubscription is the cause of slow broadband -- but what does that mean? Oversubscription comes into play in any network when the aggregate subscribed customer demand is greater than the available bandwidth. The easiest way to understand the concept is with an example. Consider a passive optical fiber network where up to 32 homes share the same neighborhood fiber. more
Are there any companies left that we can still call cable companies? Everything in the business press still refers to Comcast and Charter as cable companies and AT&T and Verizon as telephone companies. It's getting harder to justify using these traditional labels, and maybe the time is finally here to just start calling them all ISPs. After all, these four companies collectively have 80 million broadband customers... more
You can't put the telecom sector into perspective without looking at the performance of the biggest players in the industry. The pandemic has been an interesting year for both big ISPs and telecom vendors. Smaller ISPs should care about big ISP performance for many reasons. For many smaller companies, the big companies are the competition, and the big providers' strength or weakness can foretell stiffened competition or increased opportunity. more
A recent session of the Australian Computer Society (ACS) and the Australian Smart Communities Association (ASCA) masterclass on 5G, featured Dr. Ian Oppenheimer, the NSW Government's Chief Data Scientist and one of the country's most respected experts in radio technology. Ian is also the Chair of the scientific advisory board of the 6G Flagship organization, a global research organization based in Finland. This organization has just published a range of fascinating research papers on 6G. more
OneWeb, which declared bankruptcy in May, has reorganized and emerged from bankruptcy. Bharti Global, an Indian telecommunication conglomerate, and the British government each own 42.2% of the new company, and most of the rest is owned by previous investors SoftBank and Hughes Network Systems. Hughes will continue work on ground infrastructure and marketing and the original joint venture with Airbus, which designs and manufactures OneWeb satellites... more
A group of major telecommunications companies -- Vodafone, BT, Telefonica and Deutsche Telekom -- recently announced something a bit unexpected. In the Open BNG Operator Position Paper, they call for a fundamental, industry-wide change to the way broadband networks are built. Specifically, they advocate for collaboration throughout the telco world, with a convergence around open broadband network gateways (BNGs). more
No, not the COVID curve - the curve of U.S. engagement in global industry 5G activities. Let me explain. What is known as 5G actually consists of a broad array of fundamentally revolutionary virtualization platforms that are constantly, collectively developed by industry in several dozen open global bodies. These bodies meet every few weeks, and several score companies around the world process scores to hundreds of input documents to produce many hundreds of effectively mandatory... more
SpaceX is now serving customers (aka beta testers) in the northern United States. They will soon be doing so in Southern Canada and recently announced that Germany, where they have applied for permission and have begun construction on two ground stations, will probably be next. Early customers in the US are paying $499 for their user terminals and $99 per month for Internet service. more
On February 2, 1989, the Soviet Union launched its Cosmos 2004 satellite and the Chinese launched a rocket on December 15, 2009. Cosmos 2004 is now defunct, as is the third stage of that Chinese rocket, but both remain in orbit. They were long forgotten until recently when LeoLabs, a satellite tracking service, predicted that they had a good chance of colliding at 971 km over the sea near Antarctica. more
According to an email, Starlink has moved into the second phase of its beta program, nicknamed the "better than nothing beta," which feels a bit like monopoly hubris to me. It may be better than nothing, but it is not as good as the initial beta, which was free. Participants will pay $99 per month for the service and pay $499 for a terminal, including a tripod and WiFi router. I wonder what the difference is between these "beta testers" and "customers." more
In October 2020, I went on a two-week tour into Queensland's Outback, traveling through various landscapes from pastoral and agricultural lands to savanna and the desert. Leaving Brisbane, past Toowoomba, you enter the Darling Downs. This is one of the richest agricultural areas in Australia. British Botanist Alan Cunningham first explored it in 1827. However, only after the penal colony of Moreton Bay (now Brisbane) was closed, free settlers were allowed in the area. more
The statistics concerning the number of gigabit fiber customers in the US is eye-opening. OpenVault tracks the percentage of customers provisioned at various broadband speeds. At the end of 2019, the company reported that 2.81% of all households in the US were subscribed to gigabit service. By the end of the first quarter of 2020, just after the onset of the pandemic, the percentage of gigabit subscriptions had climbed to 3.75% of total broadband subscribers. more
The last two months have seen a flurry of Starlink activity, including the following: Bill Gates has a history of interest in satellite Internet and in September, Microsoft announced their Azure Obrital ground station service, which enables satellite access to its Azure cloud services. SES, Viasat, and Intelsat were announced as initial partners and SpaceX just signed up. Starlink+Azure Orbital will compete with Amazon's satellite constellation and its ground-station service... more
The web is full of stories of rural areas with no broadband options, and I've spent a lot of time in the last few decades helping rural areas get better broadband. There has not been nearly as much coverage of the huge broadband gap in urban areas. There are a lot of urban homes that can't afford broadband and, in many cases, got bypassed when the telcos and/or cable companies built their networks. more
SpaceX's Starlink project appears to be the only low-Earth orbit (LEO) satellite ISP among close to 400 ISPs to qualify to bid in a U.S. federal rural-broadband funding auction. more
