Friday Hack Chat: GNU Radio
Thursday, 30 August 2018 12:30

Software defined radio picked up a lot of popularity when it was discovered that cheap USB TV tuners were functional bits of hardware that could become SDRs. It’s the software that makes this possible, and when it comes to SDR software, there’s no better tool than GNU Radio. For this week’s Hack Chat we’re going to sit down with some of the people behind this awesome software tool and pick their brains.

Our guests for this week’s Hack Chat will be Derek Kozel and Nate Temple, officers of the GNU Radio project. They’re also organizers of this year’s GNU Radio …read more

It's a net neutrality whodunnit: Boffins devise way to detect who's throttling transit
Saturday, 25 August 2018 03:20

Back when net neutrality was a thing, engineers at the Center for Applied Internet Data Analysis (CAIDA) tested US interdomain links, and found them mostly flowing freely.

News of Verizon throttling a California fire department's data suggest things have already changed in America, but if CAIDA's work gets legs, the world will at least have a new way to detect that kind of behaviour.

Published this month after winning the ACM's SIGCOMM 2018 "best paper" accolade, "Inferring Persistent Interdomain Congestion" offers an architecture for what its 10 authors called "large-scale third-party monitoring of the Internet interconnection ecosystem".

When the group

Netadmins: Grab a plate and wander down El Reg's network buffet
Friday, 24 August 2018 23:25

The Broadband Forum has dropped the first open-source code in an access interoperability project designed to support cloud-based access infrastructure and services.

The Open Broadband – Broadband Access Abstraction (OB-BAA) project was announced here and published here .

Broadband Forum CEO Robin Mersh said the project helps network operators take an optimised approach to infrastructure rather than having to fetch the upgrade forklift.

OB-BAA specifies core components, northbound, and southbound interfaces for virtualized access devices (for example, a virtual CPE in which the "box in the home" supports connectivity and nearly nothing else, with cloud services providing smarts like the

EU tosses Nokia a small loan of €500m, tells it to go crazy with 5G R D
Tuesday, 28 August 2018 19:47

The European Union reckons 5G R&D needs a boost – so it has slung a loan of €500m in the general direction of Finland.

Nokia, recipient of the loan from the European Investment Bank (EIB) and the European Fund for Strategic Investments (EFSI), hasn't identified specific goals for its development effort.

However, EIB president Alexander Stubb told Finnish newspaper Helsingin Sanomat that Europe needs to catch up with the countries it sees as the powerhouses of 5G – China and the USA.

"We have to understand that China and the US have moved fast with the 5G. It is very

Raspberry Pi as 433 MHz to MQTT Gateway
Thursday, 30 August 2018 04:00

Many low-cost wireless temperature and humidity sensors use a 433 MHz transmitter to send data back to their base stations. This is a great choice for the manufacturer of said devices because it’s simple and the radios are cheap, but it does limit what we as the consumer can do with it a bit. Generally speaking, you won’t be reading data from these sensors on your computer unless you’ve got an SDR device and some experience with GNU Radio and reading the Nexus protocol.

But [Aquaticus] has developed a very comprehensive piece of software that should make integrating these type …read more

Blinking internets, Batman! O2 trials 5G over lightbulbs
Friday, 17 August 2018 16:01

Telefonica’s O2 has confirmed that it is experimenting with transmitting high speed data using lightbulbs, the brainchild of an Edinburgh University professor Harald Haas.

Transmitting data over the visible part of the spectrum, VLC (pdf) , has one obvious advantage over using the congested RF spectrum. The IEEE began examining it in the 1990s, but the working group it established hasn’t seen much action for a decade. What’s changed is the availability of cheap LEDs.

Harald Haas

But as Harald Professor Haas , who coined the term "Li-Fi", explained in this 2015 paper ( pdf ) - that there’s plenty of work
