21st Century Triple Networks: Ubiquitous 4G, WiFi, & Wires

The best engineers on the planet are coming to the same conclusion: a hybrid 4G/WiFi/landline network is the way to meet mobile demand. Folks like John Donovan of AT&T and Masayoshi Son of Softbank in Japan had this vision around 2007-2008. As the iPhone/iPad/Android made the coming demand clear, networks planners around the world evolved similar strategies. more

O3b Satellite Internet – Today and Tomorrow

I have written a lot about the potential of low-Earth orbit (LEO) satellites for Internet service, but have not said much about medium-Earth orbit (MEO) satellites - until now. O3b (other three billion) is an MEO-satellite Internet service provider. Greg Wyler founded the company, and it was subsequently acquired by SES, a major geostationary-orbit (GSO) satellite company. (Wyler moved on to found future LEO Internet service provider OneWeb). more

Broadband Routers and Botnets: Being Proactive

In this post I'd like to discuss the threat widely circulated insecure broadband routers pose today. We have touched on it before. Today, yet another public report of a vulnerable DSL modem type was posted to bugtraq, this time about a potential WIRELESS flaw with broadband routers being insecure at Deutsche Telekom. I haven't verified this one myself but it refers to "Deutsche Telekom Speedport w700v broadband router"... more

The Internet and the Cloud Are Going Into Space

Unlike Bezos and Branson, they're going to stay there. Today we have space-based internet access and a terrestrial internet; within ten years, we'll have a space-based internet. Internet traffic will travel more miles in space than on terrestrial fiber. By that time, the great cloud data centers of Google, Amazon, Microsoft, and their competitors and successors will mostly be in orbit as well. Five years from now, this transition will be obvious, accepted, and well underway... more

No Free Super WiFi, But the US Still Needs Improved WiFi Coverage

The FCC has long battled for a more efficient deployment of unused spectrum, endeavouring to adapt rules governing 'white space' TV spectrum (largely gifted to broadcasters years ago, and generally in the 700MHz band) to newly released spectrum (in the 600MHz band). This will considerably improve wireless broadband coverage where it is needed most... Certainly, in the US's disjointed broadband sector there are considerable challenges ahead... more

Top 4 Lessons from CCTA 2014

Sun, surf, and ... service operators? It's a match made in heaven! The Caribbean cable and telecommunications industry may not be large, but it is an important and fast-growing region. The recent Caribbean Cable & Telecommunications Association (CCTA) Annual Meeting in Puerto Rico threw the spotlight on this slice of paradise and I was there to catch up on some of the trends emerging for the year ahead. more

SpaceX Is First With Inter-Satellite Laser Links in Low-Earth Orbit, but Others Will Follow

When SpaceX first announced plans for Starlink, their low-Earth orbit Internet service constellation, they said each satellite would have five inter-satellite laser links (ISLLs) - two links to satellites in the same orbital plane, two to satellites in adjacent orbital planes, and one to a satellite in a crossing plane. They subsequently dropped the crossing link as too difficult and, when they finally began launching satellites, they had no laser links. Last year they tested ISLLs on two satellites. more

FCC Banning Wireless Devices that Interfere with White Spaces Spectrum

The Federal Communications Commission (FCC) has proposed a ban on some wireless microphones and other low-powered devices that operate in the 700-MHz band after the digital TV transition in February, next year. This is part of an attempt to clear any potential interference with the "white spaces" spectrum which will be fully available for "public safety as well as commercial wireless services". more

Identity Theft: Giving Away Your Personal Information

Identity theft is apparently the "in thing" these days. By media accounts, hackers and evildoers lurk everywhere trying to steal your personal information. In the past few months, one company after another is being forced to admit customer data has been lost or stolen. In many cases, they have them come forth repeatedly over the next few weeks, or even months revising the estimated number of impacted customers. To date, I don't think any have ever lowered those numbers. ...Let's consider two events that didn't make the front page of C|Net or CNN.  more

IPv6: Do as I Say or Do as I Do?

How important is it for a vendor, service provider or integrator to be using a service or technology that it is pushing on its clients? When Voice over IP (VoIP) came out Cisco began a gigantic push, having its salespersons pitch it to anyone and everyone on their client list. But Cisco had not yet deployed VoIP within its own corporate network. It was still making use of traditional voice systems from vendors that today it probably considers competitors. Many people on the receiving end of a sales pitch recognized this... more

The Short History of the Internet: From ARPANET to the Metaverse

Last Saturday marked the 53rd anniversary of the Internet. While the vast majority of its five billion users have been online for less than a decade, the Internet was taken into use on October 29th, 1969, when two computers connected to the ARPANET exchanged a message. Although the Internet has been around for a while, it remained below most people's radar until the late 1990s when the dot com boom started. more

FiOS: A Reality Check

I wrote this in response to some interest in my experience with the reality of FiOS. The short summary is that there is no magic. Sure having Fiber is nice but it isn't that much different than my "cable" service. The bigger difference between Comcast and Verizon is in the nature of the businesses. Comcast is a content company trying to move on to it looks beyond the STB with its purchase of NBCU whereas Verizon seems to want to continue the 1990's vision of the STB as its entrée into the home. more

The Internet’s Weakest Link

This week two major transoceanic cables experienced outages that may last several days. The outages provide a reminder that several Internet bottlenecks exist where these cables make landfall. When one thinks of bottlenecks in telecommunications the first and last mile come to mind. Yet equally vulnerable are the last few 1000 feet of submarine cable links. more

STIR Working Group Officially Formed to Work on Secure Caller ID For VoIP

Interested in working on an open standard for "secure Caller ID" for voice-over-IP (VoIP)? If so, the new "Secure Telephone Identity Revisited (STIR)" working group was just officially chartered within the IETF and the mailing list is open for all to subscribe.  more

A Brooklyn Bitcoin Mining Operation is Causing Interference to T-Mobile’s Broadband Network

The Federal Communications Commission on Thursday sent a letter to an individual in Brooklyn, New York, alleging that a device in the individual's residence used to mine Bitcoin is generating spurious radiofrequency emissions, causing interference to a portion of T-Mobile's mobile telephone and broadband network. more
