Broadband infrastructure is advancing rapidly, from multi-gigabit cable and fiber networks to next-generation fixed wireless and satellite systems. With speeds reaching up to 25 Gbps for consumers and 1 Tbps in orbit, these developments mark a pivotal shift in connectivity, setting the stage for more scalable, flexible, and high-capacity networks. more
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
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
AI technology seems to be a hot topic in every industry, and broadband is no exception. It seems inevitable that AI will be used to help monitor and control complex broadband networks. It looks like the biggest ISPs are already phasing AI into the customer service process. Nobody seems to be able to answer the big question of whether AI will change the amount of broadband the average household uses. more
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
Audacity by federal policy makers can be admirable, at least in some cases, but it can a bit more problematic in others. A case in point is the Food and Drug Administration's "deeming" of the internet to be a tobacco product. The FDA explained that it was exercising its authority under the Family Smoking Prevention and Tobacco Control Act which gave the agency an extensive set of duties, responsibilities and authorities over "tobacco products." more
A new report on 5G and geopolitics by Oxford Information Labs details the complex landscape of 5G security. Importantly, it draws out how a variety of proven technical concerns around the quality of Huawei security practices and equipment are drowned out by the US' Twitter diplomacy. Critical international dialogue on genuine cybersecurity concerns relating to 5G and Huawei are being lost in the noise of the US-China trade war. more
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
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
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
In a speech this morning, widely heralded (and criticized) as a call for "network neutrality," FCC Chairman Julius Genachowski: "Why has the Internet proved to be such a powerful engine for creativity, innovation, and economic growth? A big part of the answer traces back to one key decision by the Internet's original architects: to make the Internet an open system." Now "open system" doesn't mean anarchy. The Internet has rules, technical standards codified in the unassuming sounding "Requests for Comment." more
We're edging closer every day to seeing WiFi 6 in our homes. WiFi 6 will be bolstered by the newly approved 6 GHz frequency, and the combination of WiFi 6 and 6 GHz spectrum is going to revolutionize home broadband. I don't think many people understand how many of our home broadband woes are caused by current WiFi technology. WiFi has been an awesome technology that freed our homes from long category 5 wires everywhere, but WiFi has a basic flaw that became apparent when homeowners started to buy hordes of WiFi-enabled devices. more
This year's Cisco Collaboration Summit was a step up from last year, and I say that for good reason. Last year's event was good -- all of Cisco's events are good -- but the venue was too small and it took away from the messaging. For 2010, Cisco went out of town to the classy and classic Arizona Biltmore in Phoenix. They don't build them like this anymore, and to me, this setting did far more justice for what Cisco has to say about collaboration. more
Network neutrality is important in the context of assuring the opportunity to innovate in how we communicate and connect. We can't define it in terms of specific outcomes but rather in terms of what we enable. The Internet is just one example of what we can do when given the opportunity to use software to fashion our own solutions... I thought about this more when I found myself in my hospital room (after knee surgery) unable to open and close the shades by myself. But yet I could control the lights in my house! more
Does "voice" communication really matter as much today in business communications? Think about it. When you need to reach someone today, what do you do? Do you call them on the phone? Or do you send them email? Or a text message? or IM? I know personally that my normal communication flow usually goes something like this: Instant Messaging; I check first to see if I can reach the person on some form of IM... SMS; if the matter is relatively important... E-mail/Facebook/Twitter/other; Previously that would have just been email, but these days I find myself very often sending messages via Facebook or Twitter... more
