Damage to a single submarine cable has left the entire Red Sea region disconnected from the Internet. Kuwait, Saudi Arabia, Sudan, and Ethiopia have all suffered from the last week's cut of the so-called Falcon cable. more
I posted reviews of important LEO-satellite Internet service developments during 2017 and 2018. I've been updating those posts during the years and have 16 new posts for 2019. In 2019 we saw four inciteful simulations, Leosat suspending operations and Amazon announcing the availability of a new ground station service and plans for a LEO constellation, progress in phased-array antennas but a lowering of expectations for inter-satellite laser links (ISLLs), new competition from China... more
New York City Mayor Bill de Blasio and Chief Technology Officer John Paul Farmer today announced an Internet Master Plan for the City aimed to chart a path for internet providers in the private sector to work in partnership with the City in order to address market gaps and deliver universal broadband to New Yorkers. more
There is already a growing shortage of fiber resources that includes engineers, construction companies, and fiber consultants. The upcoming $16.4 billion RDOF program will create a resource shortage in 2020 for those who can help companies seek grant funding. Once the grants are awarded, the size of the program will add stress to the resources needed to build networks. Companies that don't line up their experts early might find themselves without help. more
Handley's simulation shows that, while not as fast as an equivalent ISLL path, long bent-pipe paths would typically have lower latency than terrestrial fiber routes between the same two points. Mark Handley, a professor at University College London, has made two terrific videos based on runs of his simulation of the first – 1,584 satellite – phase of SpaceX's Starlink Internet-service constellation. I discussed the first video, which assumes that the satellites have inter-satellite laser links (ISLLs), in recent post. more
The fiber industry is as busy as I have ever seen it, and it's about to get even busier. The cellular carriers, particularly Verizon are actively building fiber to reach small cell sites. The cable companies are building a significant amount of fiber, particularly Altice which is upgrading to FTTP. The FCC is going to award $9 billion in 2020 for the 5G Fund grant program, much which will go for fiber to reach rural cell sites. more
Ten million Chinese "reserved" 5G phones in the first two weeks of October, a powerful signal of high demand. Huawei thought they could all get phones in October. But the official figures are less than 1M 5G phones in October and ~5M in November. WTF? It could be an ordinary problem of ramping supply of a new product. It could be the official figures on phone sales are lagging reality by several weeks. more
Data transmission is one area where security should be among the biggest concerns. Overseeing data integrity is the realm of communications security (ComSec) teams, and they're getting a lot of assistance these days from artificial intelligence (AI) via machine learning and other AI components that also prove helpful in improving accessibility. Under the umbrella of AI, advances like assistive technologies promote accessibility while preserving data integrity and the flow of communications. more
Until now, the 5G industry has spread a lot of hype, but it hasn't affected customers. That's all starting to change as the cellular carriers are starting to offer 5G phones. Many customers who spend extra for 5G phones are going to quickly be frustrated and disappointed as they try to participate in the new 5G world. Consider both AT&T and T-Mobile. Both companies are introducing both a low-band and a high-band 5G phone, and customers who want 5G will have to choose... more
Developments in the telecommunications industry and the broader digital economy have opened up many new markets over the last few decades. Telecoms has changed from a more or less standalone, horizontally-organized industry to one that has become a key facilitator in a range of vertical markets. The keyword that is used to indicate that change is "smart." We are talking about smart transport, smart energy, smart cities and so on. more
We've now entered the period of 5G competition where the wireless carriers are trying to outdo each other in announcing 5G rollouts. If you believe the announcements, you'd think 5G is soon going to be everywhere. Device manufacturers are joining the fray and are advertising devices that can be used with the early carrier 5G products. Buyers beware -- because most of what the cellular companies and the manufacturers are hyping as 5G is not yet 5G. more
The U.S. Department of Agriculture has been measuring computer usage on farms and publishes the results every two years in its Farm Computer Usage and Ownership report. The most recently released report for 2019 was compiled by asking questions to 20,000 farmers. This is a large sample from the more than 2 million farms in the country. more
U.S. companies were selling $11 billion a year of parts to Huawei before the blockade. Losing those sales is just the start of the damage. Every other Chinese and Russian company is making sure to find non-US suppliers. The U.S. has threatened India and Turkey with sanctions as well. As other companies replace U.S. components, the impact will be tens of billions more than the $11 billion of Huawei suppliers. more
It's clear that even before the turn of this century that the big telcos largely walked away from maintaining and improving residential service. The evidence for this is the huge numbers of neighborhoods that are stuck with older copper technologies that haven't been upgraded. The telcos made huge profits over the decades in these neighborhoods and ideally should not have been allowed to walk away from their customers. more
German regulators have released a set of guidelines addressing network security for companies wanting to help build next-generation 5G infrastructure. more
