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
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
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
I saw a poster on the London Underground yesterday, and as is often the case it got me thinking about the parallels with telecoms. The poster explains the peak and off-peak fare structure for tube travel. The purpose of this pricing system is to manage the relationship between supply and demand in a system that is capacity constrained. Over short and medium timescales the supply is essentially fixed, and demand can oversaturate that supply. more
A Brazilian judge on Monday issued a 72-hour ban on WhatsApp chat service throughout Brazil. The measure which took effect at 2 p.m. was issued on April 26 following a failed 2013 access order from a branch of civil police that investigates criminal activity online. more
Cuba's government monopoly ISP ETECSA in October announced special home connectivity rates for some of the poorest towns in rural Cuba. The monthly charge for 30 hours of 512/256 Kbps DSL access in those towns will be 5 CUC. In other areas where home connectivity is available, the minimum monthly charge is 15 CUC for 30 hours of 1,024/256 kbps service and faster, more expensive, plans are available. more
"Many refugees regard a connected device as being as vital to them as food, water or shelter," according to a new report from the UN Refugee Agency (UNHCR), and Accenture. more
"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
Comcast today announced plans to conduct production-network trials of IPv6 technology this year. The trials are aimed at helping identify and solve any areas of difficulty involved in the transition to IPv6, and to determine what approach will be the easiest and most seamless for its customers, says Jason Livingood, Comcast's Internet System Engineer. more
U.S. regulators on Wednesday blocked some Obama administration rules on the eve of implementation, regulations that would have subjected broadband providers to stricter scrutiny than web sites face to protect customers' private data. more
From the Middle East to South Asia to Africa, shutdowns are becoming a norm of authoritarianism -- an accepted means of silencing criticism, stifling dissent, and controlling the population. Governments are increasingly using digital tools to surveil, censor, and manipulate information, as well as amplify their own propaganda. more
Cable operators face a big challenge today as data utilization continues to increase on their networks. Keeping up with the demand for high quality services while upgrading network infrastructure seems to be a never-ending task. Many times, network upgrades are done without much help from tools and systems, leaving it mostly based on experience and performance indicators defined by the operator. Unfortunately, this is the reality for far too many service providers today. more
I have on my desk a rather small tube. It's a little under 2cm in diameter, 6 cm long, and looks like it's made from a dull white polycarbonate material. At the end, I can see a copper inner tube, and inside that, another polycarbonate layer, and then a smaller steel tube that holds a thin steel thread and some fibre optic cables. There are no layers of steel jacketing, nor any other additional wrapping at all. more
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
OpenVault Just released its Broadband Industry Report for 4Q 2019 that tracks the way that the US consumes data. The results of the reports are as eye-opening as OpenVault reports for the last few years. OpenVault has been collecting broadband usage for more than ten years. As usual, the OpenVault statistics are a wake-up cry for the industry. more
