Is there an upper limit to WiFi speed?
Posted by Philip Raymond in categories: computing, internet
As with many of my recent posts, this was originally a reply to a member of Quora, a Q&A web forum. But, it fits within Lifeboat’s educational mission and our fascination to push the limits of creativity and tech.
Is there a theoretical speed limit to WiFi devices over the next 10 years?
Because of four recent practices,* it is difficult to predict an upper limit for future overall throughput:
- Channel bonding
- Beam steering (MIMO shaping and directing the antenna pattern)
- Mesh Networking (i.e. subdividing a service area into micro-cells). Residential examples: Google WiFi, Netgear Orbi or TP-Link Deco
- Ultra wideband or Ultra-high frequency: In 2017, both Netgear and Asus introduced routers with 802.11ad WiFi (‘WiFi AD’). Although it still not widely adopted, it adds a 60 GHz radio to the existing 2.4 and 5 GHz radios, supporting 7 Gbps network speed).

Note that none of these techniques demands a high output power per channel. They all use ‘tricks’ to achieve higher speeds. But the tricks are scaleable. There really is no upper limit to any of these techniques.

Marshall Islands have higher levels of radiation than Chernobyl
Posted by John Gallagher in categories: energy, military
A group of islands halfway between Australia and Hawaii have been found to contain deadly levels of radiation, 1000 times higher than toxic sites of stricken nuclear power stations at Chernobyl and Fukushima.
The Marshall Islands in the central Pacific Ocean were once an idyllic tropical paradise before they were hit with more than 60 nuclear bombs during testing carried out by the United States between 1946 and 1958.

It’s all CRUMBLING… NYC power outages to continue; GPS satellites fail; tech is collapsing at an increased rate
Posted by John Gallagher in categories: energy, satellites
(Natural News) A series of incidents that have occurred in close proximity to each other over the past several days are leading many to believe that technology is failing society and that U.S. infrastructure is collapsing faster than previously believed.
On Saturday, a wide swath of Manhattan’s West Side was plunged into darkness for several hours, and the electric company officials responsible for providing the power — Con Edison — are not sure why the failure occurred.
As reported by the New York Post, the company said in a statement late Sunday morning that it “will be conducting a diligent and vigorous investigation to determine the root cause of the incident.”

8 of the surviving Apollo astronauts got together for the 50th anniversary of the moon landing, and Buzz Aldrin’s outfit stole the show
Posted by Alberto Lao in category: space
A few months ago, ahead of the 50th anniversary of the first moon landing, eight of the 17 surviving Apollo astronauts gathered together for an early celebration at The Explorers Club in New York City.
The group was: Walter Cunningham (Apollo 7), Rusty Schweickart (Apollo 9), Buzz Aldrin and Michael Collins (Apollo 11), Fred Haise (Apollo 13), Al Worden (Apollo 15), Charlie Duke (Apollo 16), and Harrison Schmitt (Apollo 17).
