5G Mobile via LEO Broadband Satellites Moves a Step Closer

12th July, 2022 (5 Comments)

The idea of being able to offer consumers a 5G based mobile handset that gets its service from orbiting broadband satellites in Low Earth Orbit (LEO), as well as a terrestrial mast, is nothing new. But turning it into a commercial product is another thing entirely, yet Ericsson, Qualcomm and Thales appear to be making progress.

Nokia Demo 100Gbps Full Fibre PON Prototype Outside Lab

13th June, 2022 (0 Comments)

Following last year’s successful lab tests, Nokia has brought their future 100G PON (Passive Optical Network) technology to be showcased at the “Fiber Connect” event in Nashville (USA). The new kit is capable of delivering full fibre 100Gbps speeds in downstream on a single PON wavelength in a real-world environment.

Birmingham Scientists Create New 5G Beam Steering Antenna

6th June, 2022 (8 Comments)

A team from the University of Birmingham‘s School of Engineering in England has developed a new beam-steering antenna for future 5G and 6G mobile (mobile broadband) networks, which claims to have achieved “vast improvements in data transmission efficiency” via a range of frequencies that are “inaccessible” to existing technologies.

Scientists Improve Earthquake Detection via Subsea Fibre Cables

20th May, 2022 (0 Comments)

Scientists have found a way to further improve the detection of earthquakes by harnessing the unique properties of existing subsea fibre optic cables – specifically their repeaters, which straddle the ocean floors between countries and are used to carry vast amounts of data. The study used the 5,860km EXAI cable between the UK and Canada.

BT Trials Quantum Radios to Boost Future UK 5G Mobile Cover

18th May, 2022 (12 Comments)

Telecoms giant BT (EE) has begun to trial a new “hyper-sensitive quantum antenna technology using excited atomic states,” which represents a new way of detecting radio waves that could find much weaker signals than conventional receivers and thus boost the capabilities of future 5G mobile (broadband) and IoT networks.

Samsung Sets Out Plan for 6G Mobile Broadband at 1Tbps Speeds

12th May, 2022 (22 Comments)

South Korean tech giant Samsung, which has historically played a major role in the development of new mobile network technologies, has this week published some of its early research findings into the future 6th Generation (6G) of mobile broadband technology and set out what sort of technologies it may incorporate.

Study Tests the Theoretical Limits of Copper Line Broadband

28th April, 2022 (34 Comments)

New research from the University of Cambridge – supported by BT and Huawei – has attempted to identify the theoretical limits of Openreach’s standard UK copper broadband lines (unshielded twisted copper pairs), while harnessing up to 12GHz of spectrum. The result is faster speeds are possible, but full fibre is still the future.

World’s First as UK Firm Links 5G Broadband via the Stratosphere

3rd March, 2022 (6 Comments)

Cambridge-based company Stratospheric Platforms has announced the “world’s first” 5G (mobile broadband) transmission from Earth’s stratosphere, which at 45,000ft managed to maintain the signal for 5 hours and achieve a broadband download speed of 90Mbps to a retail Smartphone on the ground.

Royal Astronomical Society Criticises LEO Broadband Satellites

3rd December, 2021 (10 Comments)

The Royal Astronomical Society (RAS) has warned that new Low Earth Orbit (LEO) based ultrafast broadband satellites, such as from SpaceX’s Starlink and British-registered OneWeb, will have a “significant” impact on radio astronomers and could put at risk hundreds of millions of pounds of UK investment in space research.

UK Government Launch Bid for Seat on the UN Telecoms Council

10th November, 2021 (0 Comments)

The UK Government will today launch its election manifesto as part of efforts to secure a seat on the governing council of the International Telecommunications Union (ITU), which will give it more of a say in future standards (broadband, satellite technologies etc.) and the allocation of global spectrum (mobile etc.) etc.

Dorset Project Demos Satellite Backhaul from a 5G Standalone Network

8th November, 2021 (3 Comments)

The 5G RuralDorset project, which is testing various 5G based mobile voice and broadband technologies alongside existing fibre cables, claims to have achieved a “world-first” by demonstrating satellite backhaul from a 5G Standalone network (i.e. using satellite to keep the connection live when terrestrial mobile fails).

BT Test Robots to Help Build and Fix UK FTTP Broadband Ducts

8th November, 2021 (5 Comments)

Telecoms giant BT has confirmed that they’re working with the UK university sector and other utilities to develop and trial a new range of robots, which they hope could be used by Openreach and others to help speed up the rollout of gigabit-capable Fibre-to-the-Premises (FTTP) broadband ISP networks and fix them when broken.

Six Big UK ISPs Ordered to Block Five Piracy Streaming Websites

25th October, 2021 (25 Comments)

Several major UK broadband ISPs, including BT, EE, Plusnet, Sky Broadband, TalkTalk and Virgin Media (VMO2), have been ordered by London’s High Court to block six more streaming websites after they were found to be facilitating internet copyright infringement (piracy).

Court Orders UK ISP TalkTalk to Block More Piracy Websites

14th October, 2021 (28 Comments)

Budget broadband ISP TalkTalk has this week updated their list of blocked websites (i.e. those where they’ve been told to do so by the UK High Court) to include a number of new sites that, following an injunction secured by the Motion Picture Association (MPA), were found to be facilitating internet copyright infringement.

Nokia Claims Solution to the Problem of mmWave 5G Broadband

13th October, 2021 (3 Comments)

Nokia claims to have moved closer to turning multi-gigabit speed capable 5G mmWave broadband for homes into a reality by developing a new type of “very high gain antenna” with a “360 Field of View,” which they say can overcome at least some of the usual signal propagation issues.
