Will Cisco Make a Comeback in Cuba?

Is the recently announced Cisco Networking Academy at the Universidad de Ciencias Informáticas a belated drop in the bucket or the first step in a significant opening? Cisco dominated the infrastructure equipment market in Cuba and elsewhere during the early days of the Internet, but Huawei replaced them in Cuba... What does this mean? It might be a belated drop in the bucket. UCI has only 19 trained CNA instructors while the CNA curriculum is being taught by over 20,000 instructors at over 10,000 institutions. more

Zero Rating: Something Is Better Than Nothing! Or Is It?

One of the primary purposes of global Internet Governance Forum (IGF) is to introduce a wide range of topics to newcomers and provide them with the opportunity to take back what they have learned in the hopes of establishing an understanding of the Internet Governance philosophy at the community or national level. As a first time participant at the 10th Global Internet Governance Forum (IGF 2015) that took place in Joao Pessoa Brazil, in early November of 2015, I felt the burden of being a representative from a developing country, a place where discussion of important issues is limited to a small group of individuals, often in informal settings, over coffee or in my case, green tea. more

Are You Ready for 10 Gbps?

Around the world, we're seeing some migration to 10 Gbps residential broadband. During the last year, the broadband providers in South Korea, Japan, and China began upgrading to the next-generation PON and are offering the blazingly fast broadband products to consumers. South Korea is leading the pack and expects to have the 10 Gbps speed to about 50% of subscribers by the end of 2022. more

Net Neutrality: What Is Old Is New Again

On July 22, the FCC's open Internet order - which transforms Internet access service from a lightly regulated information service into a heavily regulated telecommunications service - will take effect. This article describes the policies and legal theories underlying the Order and the Order's effect on consumers of Internet services and providers of the service, including a number of entities that had previously escaped FCC regulation. more

Clues about the Future of TV

A recent article chronicles the telcos' slow start in cable TV. I don't think the telcos stand a chance of succeeding in cable TV. Instead, if they're to succeed at all, they'll probably buy or form alliances with existing cablecos... But they'd better start swimming, because the times are a changing.. more

Is IPv6 Wrestling Within an Unpredictable Telecommunications Industry?

The theme of the 40th International Institute of Communications (IIC) conference in Montreal this week was "Wrestling with unpredictability in Global Communications". The panel I had the pleasure to be part of was under the motto : "Broadband futures". One of the questions addressed to me : Should we be concerned about a shortage of IP addresses as more people use broadband networks for more things? more

US-China Tech War Threatens Global Internet Infrastructure: China Plans $500 Million Subsea Cable Rival

Chinese state-owned telecom firms plan an extensive undersea fiber-optic internet cable network to link Asia, the Middle East, and Europe. The cable, to be named EMA (Europe-Middle East-Asia), would cost approximately $500 million to complete and be manufactured and laid by China's HMN Technologies Co Ltd, a fast-growing cable firm whose predecessor company was majority-owned by Chinese telecom giant Huawei Technologies Co Ltd. more

SpaceX Starlink’s Variable Pricing Pilot in France Is Good Business and Good Karma

Starlink is available in 37 nations, and the price for best effort service was the same everywhere until August 3, when variable pricing with throttling became available in France. I predicted they would eventually shift from uniform to affordable pricing some time ago, but why did they do it now? Starlink first became available in the U.S. and Canada, and sales are beginning to outrun the available capacity. more

4G on the Moon

This post is a little more lighthearted than my normal blog posts. An article in FierceWireless caught my eye talking about how Nokia plans to establish a 4G network on the Moon. The primary purpose of the wireless technology will be to communicate between a base station and lunar rovers. 4G LTE is a mature and stable technology that can handle data transmission with ease... more

Reflections on the Pandemic Effect on Internet Use and Democracy

Last year, around the same time, the release on the same day of two flagship reports on 'the Internet' had prompted me to write an article on CircleID entitled 'Connecting the Next 46 Percent: Time to Pick the Good From the Bad and the Ugly'. I was then prudently asking whether 'the more we connect the world, the less free it becomes?'. Who would have known that a pandemic would erupt a few months later, unveiling different perspectives in assessing that very same question? more

Constraints on Satellite Broadband: Starlink Alone Unable to Meet Rural Broadband Demand

In a 2024 end-of-year memo, Gary Bolton of the Fiber Broadband Association said that FBA had partnered with the consulting firm Cartesian to look at the pros and cons of Starlink in the U.S. FBA says that report shows that Starlink currently has 1.4 million customers in the U.S., and with the current satellite constellation has the capacity to serve 1.7 million customers. more

Investing in Rural Broadband

There was a headline in a recent FierceTelecom article that I thought I'd never see - Jeffries analyst says the rural broadband market is ripe for investment. In the article, analyst George Notter is quoted talking about how hot rural broadband is as an investment. He cites the large companies that have been making noise about investing in rural broadband. Of course, that investment relies on getting significant rural grants. more

Whose Network is it Anyway?

In reading a Q&A with Verizon's Brian Whitten I found this striking Q and A: "Q. With a fiber connection being symmetric, many fiber providers such as Paxio are providing symmetric connections such as 5Mbit, 10Mbit, 30Mbit. Why is Verizon keeping this arbitrary asymmetric limit with Fiber? A. ...Indeed, our FTTP network can easily support a symmetric data service. As market dynamics change, we would re-assess the benefit to our customers of introducing a class of symmetric data services." My reaction is "No thank you, I'd rather do it myself". To understand my reaction you need to recognize the difference between wanting to build my own bridge across a stream and asking why I'm not allowed to cross it myself using my own boat. more

Will Work for Bandwidth

The Internet is in for interesting times. Previously, on Renysys' blog I wrote about the engineering issues and the policy issues facing us over the next five years. But there is at least one large issue still lurking. Most of you will not be surprised to learn that almost all of these issues are outgrowths of a single factor: money. The core of the Internet still doesn't have a sustainable business model. more

Fiber to the Home: Ideal Economic Stimulus?

This week, the headlines seem to be full of fresh doom and gloom for wireline carriers, who employ people in every congressional district across America. Sooner or later, someone is going to call for Congress to tap some of the hundreds of billions in 2009 economic stimulus to help the LECs through troubled times, save lots of jobs, and preserve the way we do business in our critical last-mile communications infrastructure. Is this wise? Is there a better way? more
