Scientists Detect Earthquakes Using Subsea Fibre Optic Cable

27th February, 2021 (0 Comments)

Seismologists in California have teamed up with Google to develop a clever new way of detecting Earthquakes by harnessing the internet giant’s existing 10,500km long “Curie” subsea fibre cable, which can transmit data at speeds of 72Tbps (Terabits per second) – via four 18Tbps fibre pairs – between the USA and Chile.

Court Order Forces UK ISP TalkTalk to Block Sci-Hub Website

18th February, 2021 (17 Comments)

Broadband ISP TalkTalk has this week updated their list of blocked websites (i.e. those where they’ve been ordered by the UK high court to do so) to include the controversial Sci-Hub, which describes itself as being “the first pirate website in the world to provide [free] mass and public access to tens of millions of research papers.”

Fibre Broadband Association Challenges Starink’s Capacity to Deliver

9th February, 2021 (14 Comments)

The Fiber Broadband Association, which represents FTTP networks and suppliers in the USA, has published a new study that claims Elon Musk’s new constellation of Low Earth Orbit (LEO) based Starlink broadband satellites will face a “capacity shortfall” by 2028 and over 56% of their “RDOF subscribers” (rural) may not be fully served.

World’s First as Vodafone and Nokia Trial 100Gbps Broadband

2nd February, 2021 (6 Comments)

At present some of the fastest consumer available and Fibre-to-the-Premises (FTTP) based broadband ISPs in the world can offer speeds of up to 10-20Gbps (Gigabits per second), but a new trial by Vodafone and Nokia’s Bell Labs division has just provided a glimpse into the future by achieving speeds of 100Gbps on a single PON wavelength.

Google Scraps Project Loon – 4G Rural Broadband via Balloon

22nd January, 2021 (10 Comments)

Maybe it was just a lot of hot air but Google (Alphabet) has announced that Loon, their long-running project that aimed to deploy mobile broadband (4G / 5G) connectivity from High Altitude Platforms (stratospheric balloons), is “winding down” as a company after they struggled to turn it into a commercial success.

Mobile Operators Reject Call to Stop 5G Rollout Over Health Fears UPDATE

19th January, 2021 (0 Comments)

The trade association for UK mobile operators, Mobile UK, has warned that calls for the 5G rollout to be delayed on health grounds are “without merit“. The commentary comes after Professor John William Frank (University of Edinburgh) alleged that the transmitter density required for 5G may be “potentially harmful to health.”

Softbank Invests $350m in OneWeb’s LEO Satellite Broadband Network

15th January, 2021 (6 Comments)

In an interesting development OneWeb, which is owned by a consortium of the UK Government and Indian conglomerate Bharti Global (here), has secured an investment of $350m (c.£257m) from Japanese company Softbank – the same firm that effectively forced it into bankruptcy last year by putting a stop on further funding.

Australia Sets New Distance Record for 1Gbps Speed via 5G mmW UPDATE

13th January, 2021 (2 Comments)

The nbn™ Fixed Wireless network in Australia has just set what appears to be a new “world record” after it reached a broadband speed of “close” to 1Gbps (1000Mbps) via 5G mobile technology in a millimetre-wave (mmWave) band, using about 400MHz of spectrum bandwidth, over a distance of 7.3km.

New Record as Speed of 1Pbps Hit in Multi-Mode Optical Fibre

11th January, 2021 (7 Comments)

An international team of researchers from Japan, the USA and France has managed to achieve a world record data transmission speed of 1 Petabit per second (or 1,000,000 Gigabits) in a single-core multi-mode optical fibre cable, which is 2.5 times faster than the previous record of 0.4Pbps.

Airbus May Move OneWeb Satellite Manufacturing to UK After All

27th December, 2020 (11 Comments)

Space firm OneWeb, which is owned by a consortium of the UK Government and Indian conglomerate Bharti Global (here) and is in the process of building a mega constellation of “high-speed” broadband satellites in Low Earth Orbit (LEO), may move their Airbus supported manufacturing base to the UK.. eventually.

OneWeb UK Successfully Launches 36 LEO Broadband Satellites

18th December, 2020 (13 Comments)

As promised space company OneWeb, which is owned by a consortium of the UK Government and Indian conglomerate Bharti Global (here), has today successfully launched their next batch of 36 high-speed broadband capable Low Earth Orbit (LEO) Satellites – built with support from Airbus – into orbit.

BT Aim to Establish UK’s First Commercial Drone Corridor

15th December, 2020 (0 Comments)

Broadband and mobile giant BT has today announced that they will lead a new Government backed consortium as part of ‘Project XCelerate‘, which seeks to establish the UK’s first commercial drone corridor in open and unrestricted airspace (i.e. enabling automated drones and manned aviation to safely co-exist).

World Distance Record as 5G mmW Pushes 1Gbps Over 6.5km

7th December, 2020 (17 Comments)

A new world record has been achieved after a collaboration between TIM, Ericsson, Casa Systems and Qualcomm resulted in the companies, for the first time, reaching a broadband speed of 1Gbps over a distance of 6.5km from a radio antenna. This was done using 5G tech in the millimetre-wave (mmWave) band on a live network.

5G Mobile Networks up to 90% More Energy Efficient Than 4G

2nd December, 2020 (11 Comments)

A new joint study between Telefonica (e.g. O2 UK) and telecoms kit maker Nokia, which focused on the power consumption of the RAN (Radio Access Network), has claimed that the latest generation of ultrafast 5G based mobile (mobile broadband) networks are up to 90% more energy efficient “per traffic unit” than existing 4G ones.

The Clever Way Augmented Reality May Help Rollout Full Fibre

27th November, 2020 (10 Comments)

The on-going rollout of gigabit-capable Fibre-to-the-Premises (FTTP) based broadband ISP networks across the UK, as well as in other countries, may soon be starting to benefit from the use of Augmented Reality. This can help engineers to see – with more clarity than ever – exactly what sort of infrastructure already exists under the surface.

Study Finds Full Fibre is the Most Energy Efficient Broadband

26th November, 2020 (21 Comments)

A new study from the Prysmian Group, which was commissioned by cable manufacturer Europacable, has found that Fibre-to-the-Premises (FTTP) based broadband ISP networks are the most energy efficient of consumer fixed line technologies, compared with FTTC (VDSL2) and Hybrid Fibre Coax (DOCSIS 3 networks, like Virgin Media).
