In a study of the Internet in China in the late 1990s, my colleagues and I observed that "China has been able to execute plans effectively by allocating resources to competing, government-owned enterprises," and Kai-Fu Lee shows that they have pursued a similar strategy with respect to AI. Now they are doing the same with low-Earth orbit (LEO) broadband satellite constellations. more
There is a lot of public sentiment against placing small cell sites on residential streets. There is a particular fear of broadcasting higher millimeter wave frequencies near to homes since these frequencies have never been in widespread use before. In the public's mind, higher frequencies mean a greater danger of health problems related to exposure to radiofrequency emissions. more
I have bad news for anybody still clinging to their flip phones. All of the big cellular carriers have announced plans to end 3G cellular service, and each has a different timeline in mind... The amount of usage on 3G networks is still significant. GSMA reported that at the end of 2018 that as many as 17% of US cellular customers still made 3G connections, which accounted for as much as 19% of all cellular connections. more
As the rollout of fiber to the home project (FttH) remains a slow process, it is no wonder that more and more people are looking towards mobile as a potential alternative. Obviously, mobile communication has improved over recent years in providing excellent access to broadband. It has also become more affordable. At the same time, there is the hype surrounding 5G, and the public relations and media machines of the vendors involved makes you believe that this will become a real competitor to the slow-moving FttH developments. more
For the first time in my memory, broadband has entered into U.S. presidential politics. This is an important milestone for rural broadband – not because of the proposals being made by candidates, but because it indicates that the voices of those without rural broadband have reached upward to the top of the political system. I'm sure that when the presidential candidates go to rural areas, they are asked if they can help find a solution for the lack of broadband in many rural counties. more
Opensignal recently published a report that looks around the world at the quality of cellular video. Video has become a key part of the cellular experience as people are using cellphones for entertainment, and since social media and advertising have migrated to video. The use of cellular video is exploding. Netflix reports that 25% of its total streaming worldwide is sent to mobile devices. The new Disney+ app that was just launched got over 3 million downloads of their cellular app in just the first 24 hours. more
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
