Link: https://www.theguardian.com/technology/2017/mar/11/is-5g-the-future-robots-delivering-pizza-house-viewing-vr

5G, which is set to be rolled out in the UK next decade, also has its critics. They argue consumers don’t need the superfast speeds the upgrade from current 4G technology promises, and many in the industry believe that logistical issues mean that 5G may not be adequately rolled out in the UK for decades. In the meantime, there are still fundamental infrastructure issues – including rural areas with little or no broadband coverage at all – that need sorting out. Also, 5G could be used to enable driverless cars to communicate with each other and other road users, as well as develop “smart manufacturing” – connecting all the various machines involved in a production chain – and the drone delivery networks that companies such as Amazon would like to develop.

24. How Does Airplane Wifi Works?

Link: http://www.telegraph.co.uk/travel/travel-truths/how-does-inflight-wi-fi-work/

Link (Video): https://www.youtube.com/watch?v=x8xUzF__hcg

There are mainly two different methods in which we can get Wifi onboard planes. The first method is through ground-based mobile broadband towers which send signals up to the aircraft’s antennas. Similar to how we connect to different cell towers through our phones when we travel to different locations on land, the aircraft connects to the nearest ground-based cell towers throughout the flight allowing for a seamless wifi connection onboard. However, when the aircraft is across vast oceans or remote areas where there are no cell towers in the vicinity, the second method is employed for a wifi connection. This second method relies on satellites where planes send the information to geostationary satellites and these satellites act as a middleman between the plane and the ground-based systems by sending and receiving information through its transmitter and receiver.

38. Myth: Shark Bites Cable? When and How Cables Go Down

Link: https://blog.telegeography.com/what-happens-when-submarine-cables-break

Link (Video): https://www.youtube.com/watch?v=XMxkRh7sx84

Cable faults are common. On average, there are over 100 each year. The majority of damage to submarine cables comes from human activity, primarily fishing and anchoring, not sharks. Cables are engineered with a minimum design life of 25 years, but there is nothing magical about this time span. Cables may remain operational longer than 25 years, but they’re often retired earlier because they’re economically obsolete. They just can’t provide as much capacity as newer cables at a comparable cost and are thus too expensive to keep in service.

49. A flaw in Hotspot Shield can expose VPN users, locations

Link: http://www.zdnet.com/article/privacy-flaw-in-hotspot-shield-can-identify-users-locations/

A security researcher has found a way to identify users of Hotspot Shield, a popular free virtual private network service that promises its users anonymity and privacy. However, an information disclosure bug in the privacy service results in a leak of user data, such as which country the user is located, and the user’s Wi-Fi network name, if connected. That information leak can be used to narrow down users and their location by correlating Wi-Fi network name with public and readily available data. This could put Hotspot Shield users in an authoritarian state at risk.

While most now make use of much hyped-up data connections including 3G and 4G instead of the traditional wi-fi networks, observations have shown that wi-fi connections are still much more effective, when they are available. Wi-fi networks provide a faster and more consistent internet experience despite certain hiccups from time to time.

 

51. Will we ever… face a wireless ‘spectrum crunch’?

Link: http://www.bbc.com/future/story/20131014-are-we-headed-for-wireless-chaos

With the advancement of wireless technology, we are transmitting data almost everywhere we go. The need and demand for data and spectrum is rising, especially so in the recent years. This is causing a significant risk of a spectrum crunch by 2020. If this problem is not attended to, it will eventually cause everything to slow down. Currently, there is a need to create an extra spectrum. However, it is not as easy as it sounds as it involves a lot of costs and effort to do so. Another way to alleviate this problem would be to shrink the electromagnetic footprint of our digital communication.

The article talks about how National Security Agency (NSA) has used a secret channel of radio waves transmitted from covertly installed computer hardware to monitor about 100,000 computers around the world, allowing the spy agency access to the computers even if they aren’t connected to the internet. It talks about relying on a covert channel of radio waves that can be transmitted from tiny circuit boards and USB cards inserted surreptitiously into the computers.

 

55. Creating antennas that hijack in the air radio signals

Link: https://www.sciencenewsforstudents.org/article/these-antennas-turn-anything-radio-station

2 graduates from the University of Washington in Seattle had a project to turn anything into a radio station using these antennas. The scientists tested their device with a poster – advertising a Seattle concert by Simply Three, a string trio. People standing almost 4m away from the poster could use FM receivers on smartphones to listen to snippets of the band’s music. Those in cars as far as 18m away could use car radios to pick up the songs. The device only needs enough power to change the waves, not generate them.

This article talks about a new method for transmitting scientific reference signal that could bring significant benefit to astronomy. Researchers have demonstrated that a stable frequency reference can be reliably transmitted more than 300 kilometres over a standard fibre optic telecommunications network and used to synchronize two radio telescopes.

 

61. Wi-Fi on rays of light: 100 times faster, and never overloaded

Link: https://www.sciencedaily.com/releases/2017/03/170317102428.htm

Slow Wi-Fi is a source of irritation that nearly everyone experiences. Researchers have come up with a surprising solution: a wireless network based on harmless infrared rays. The capacity is not only huge (more than 40Gbit/s per ray), but also there is no need to share since every device gets its own ray of light. Each wireless device is assigned to different wavelengths by the same antenna, and there is no longer interference with neighbouring wifi network.

 

62. Computer Algorithm can spot a drunken tweeter

Link: http://blogs.discovermagazine.com/d-brief/2016/03/17/algorithm-drunken-tweeter/#.WoWzIZP1XBI

With the help of a machine-learning algorithm, researchers from the University of Rochester cross-referenced tweets mentioning alcohol consumption with geotagging information to broadly analyse human drinking behaviour. They were able to estimate where and when people imbibed, and, to a limited extent, how they behaved under the influence. The experiment is more than a social critique — the algorithm helps researchers spot drinking patterns that could inform public health decisions and could be applied to a range of other human behaviours.
