wireless internet radio spectrum frequency

1st December, 2016 - 12:24 pm (3 Comments)

Researchers from Japan have managed to boost the speed of WiFi data transmissions to 34Gbps (Gigabits per second) by harnessing the 500GHz band of radio spectrum, which falls within the TeraHertz range (300GHz+). Even faster speeds are coming, but distance may be a problem.

A recent study from Qualcomm Technologies has concluded that home WiFi (WLAN) wireless networks will need more than double the current amount of radio spectrum (around the 5GHz band) to deliver “sustained” speeds of 1Gbps (1000Mbps+) throughout an entire home.

AirGig Powerline Wireless Broadband

23rd September, 2016 - 1:05 am (9 Comments)

The research and development division of global telecoms giant AT&T has begun to develop a new twist on the old Powerline Communications idea, but instead of sending electrical signals over the national grid’s power cables it would use the cables to “guide” a wireless broadband transmission.

19th September, 2016 - 10:41 am (3 Comments)

A joint team of researchers working for Nokia Bell Labs, Deutsche Telekom T-Labs and the Technical University of Munich in Germany has successfully used a new technology to push 1Tbps of real-world data transfer over a pure fibre optic cable to hit close to its theoretical maximum (The Shannon Limit).

25th August, 2016 - 8:17 am (0 Comments)

Researchers working at the Massachusetts Institute of Technology (MIT) have developed a more efficient way of coordinating multiple wireless broadband routers at the same time by using their new MegaMIMO 2.0 technology, which could deliver three times faster WiFi speeds and double the range.

A team of German scientists have successfully achieved a record data rate of 6Gbps (Gigabits per second) over a distance of 36.7 kilometres by harnessing part of the E band spectrum, which operates at a radio frequency of 71-76GHz (GigaHertz). The new development could be used to boost both terrestrial and Satellite broadband capacity links.

5g uk mobile broadband

30th March, 2016 - 10:44 am (0 Comments)

Future 5G based Mobile Broadband networks are expected to be extremely fast (peak speeds of up to 10Gbps), but new EU supported research taking place at the University of West of Scotland (UWS) could also make them “self-healing” to boost performance, protect against DDoS attacks and recover faster from outages.

23rd February, 2016 - 9:36 am (5 Comments)

Most EU and UK telecoms regulators don’t expect the first commercial roll-out of future 5G capable Mobile Broadband services to happen until 2020 or later, but that hasn’t stopped Nokia and Verizon aiming for it to be launched far sooner.. in 2017! Field trials have already begun.

A team of researchers working out of the University College London have given fibre optic communications technology a further boost by achieving the highest data throughput ever reported (1.125 Terabits per second) for a single coherent optical receiver.

wireless internet radio spectrum frequency

11th February, 2016 - 11:36 am (4 Comments)

Last week we reported that Japanese scientists had managed to build a wireless network that could send data at a speed of 56Gbps (Gigabits per second) using the 72-100GHz (GigaHertz) radio frequency bands (here) and now another team claims it can hit 100Gbps by pushing into the TeraHertz (300GHz+).

3rd February, 2016 - 8:01 am (1 Comment)

Japanese scientists have demonstrated (lab test) a new low power CMOS wireless transceiver chip that can deliver data speeds of 56Gbps (Gigabits per second), which could be used by mobile operators to replace expensive fibre optic cables to their base stations. But there’s a catch.. distance.

LED Light Bulbs

25th November, 2015 - 11:43 am (4 Comments)

It’s been a long time coming but the new Light Fidelity (LiFi) technology, which can turn LED (Light-Emitting Diode) based home and office lighting or display systems into a sophisticated wireless communications network like WiFi, has finally started to reach the commercial pilot phase.

BT engineer at work

20th October, 2015 - 2:42 pm (61 Comments)

Forget BT’s plan to deploy “ultrafast” 300-500Mbps capable G.fast broadband technology to 10 million UK premises by 2020 (here). Today the operator has joined with Alcatel-Lucent to test future XG.FAST (G.fast2) technology, which under lab conditions has just pushed aggregate speeds of 5.6Gbps over 35 metres of copper cable.
