ETRI lays the groundwork for convenient and safe drone flight
2023-05-22
(Press-News.org) The lack of a single communication standard among drone makers has made it difficult for information to be shared between drones, but a Korean research team has found a solution.

The Korea Electronics and Telecommunications Research Institute (ETRI) announced that four contributions related to the ‘Unmanned Aircraft Area Network’ were established as international standards at the International Organization for Standardization (ISO*) meeting in Vienna, Austria.
* ISO/IEC JTC1/SC6(communication and information exchange between systems)

The technology towed by the research team as an international standard is a drone distributed communication standard technology that prevents the risk of collision between drones when flying drones(unmanned aerial vehicles) and supports the simultaneous operation of hundreds of drones.

The international standards established this time are standards for unmanned aerial vehicle communication networks(UAAN), and covers four detailed technologies: ▲unmanned aerial vehicle communication model and requirements ▲shared communication ▲control communication ▲video communication.

As ETRI researchers' drone distributed communication technology has been confirmed as an international standard, the market outlook is also bright as the technologies to be developed in the future will lead to international standard patents in quantity.

The core technology of this international drone communication standards is 『Evolved Wireless Ad-hoc Network(EVAN*)』 technology. EVAN technology, as a hyper-connected original technology that will lead the future society, was applied to the development of the international standards for this ‘unmanned aerial vehicle communication network’ and was recognized by standard experts around the world.
* Evolved wireless ad-hoc network: Unlike LTE, which requires a base station, a modern communication network that uses an auxiliary channel that serves as a base station instead of having a base station

With the application of EVAN technology in the drone field, it became possible to share information between drones, prevent collisions between large-scale drones, and prevent collisions with ground movement obstacles based on it. The recognition service communication distance of this standard is about 5 km, which allows drones as well as drones and helicopters to be mutually recognized, thereby securing flight safety of manned and unmanned aircraft at the same time.

For example, it was difficult for drones from different manufacturers to fly to spray pesticides on large farmland simultaneously, or for several drones to fly over the fire area simultaneously in the event of a large fire, but the technology solved these problems.

In particular, the research team explained that compared to the heavy and expensive drone recognition radar, the communication modem of the 'UAAN' standard can be manufactured inexpensively and lightly in the tens of thousands of won, making it very suitable for drone recognition service.

In addition, ETRI explained that this standard technology enables interconnection of drones as well as related devices. In other words, drone-related services such as drone control and drone image transmission, mutual recognition between drones, autonomous collision avoidance, illegal drone detection, mobile obstacle recognition, and communication with takeoff and landing sites can be provided as an integrated communication platform.

Through this, Korea will be the only country in the world capable of autonomous collision avoidance between drones by utilizing the international standard for 'Unmanned Aircarft Area Network' and the 'Low Altitude Unmanned Aircraft Detection and Avoidance Application Layer Technology' standard of the Korea Telecommunications Technology Association(TTA).

Also, if the communication modem of this standard is installed on a moving obstacle that is not displayed on the map, it is of great help in autonomous drone flight. In addition, it supports services such as direct communication with Vertiport, a drone taxi take-off and landing site, and provision of flight priority(dynamic geofencing) when maintaining bridges or surveying buildings, and if applied to defense drones, it can overcome North Korea's radio interference.

ETRI researchers explained that in this standard, since the drone transmits a password(trust field*) that changes with each signal transmission, it is possible to automatically determine whether the drone is a legitimate drone or an illegal drone from the ground.
* Trust field: Password that changes every 2ms slot. Similar to banking OTP technology. Valid only in the slot that receives the packet.

Furthermore, it was disclosed that ETRI's 'Unmanned Aircarft Area Network' standard can be utilized for PAV(Personal Air Vehicle) communication, such as drone taxis. Disconnection of the mobile communication network is fairly common in the air, unlike on the ground, and this standard is particularly ideal as a communication standard to supplement this. Internationally, communication redundancy is an essential requirement for Urban Air Mobility(UAM*).
* Urban Air Mobility(UAM): A futuristic metropolitan public transit system that makes use of the sky as a passageway.

Lim Chae-deok, head of the Air Mobility Research Division at ETRI, said, “The establishment of this international standard will secure drone operation stability, which is essential for servicing commercial drones, while with EVAN technology, its core, it is easier to configure an adaptive communication network compared to mobile communication such as LTE and 5G and Wi-Fi and has high transmission efficiency, so it will be of great help in leading fast and convenient future air mobility services in the future.”

According to ETRI researchers, EVAN technology will be expanded to a single communication platform that will provide a variety of services such as home/home appliances/vehicle control, indoor navigation, smartphone kiosk connection, children's safety on the way to and from school, cannon vehicle arrest, and search for missing persons.

Siblings with autism share more of dad’s genome, not mom’s

Siblings with autism share more of dad’s genome, not mom’s
2023-05-22
Cold Spring Harbor Laboratory (CSHL) researchers have flipped the script on autism spectrum disorder (ASD) genetics. Scientists long thought that siblings born with ASD share more of their mother’s genome than their father’s. But CSHL Associate Professor Ivan Iossifov and Professor Michael Wigler have now shown that, in many cases, it’s dad who might be playing a bigger genetic role. Autism spectrum disorders cover a range of neurological and developmental conditions. They can affect how a person communicates, socializes, learns, and behaves. ASD may also manifest as repetitive behaviors ...

Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world

Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world
2023-05-22
An international team has used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by volcanic eruptions could produce an equatorial plasma bubble (EPB) in the ionosphere, severely disrupting satellite-based communications. Their findings were published in the journal Scientific Reports.  The ionosphere is the region of the Earth's upper atmosphere where molecules and atoms are ionized by solar radiation, creating positively charged ions. The area with the highest concentration of ionized particles is called the F-region, an area 150 to 800 km above the Earth's surface. The F-region plays ...

Adverse pregnancy outcomes increase stroke risk

Adverse pregnancy outcomes increase stroke risk
2023-05-22
Investigators from the Smidt Heart Institute at Cedars-Sinai found that women who experience an adverse pregnancy outcome—such as gestational hypertension, preeclampsia or preterm birth—have a higher risk of developing stroke in their lifetime, and at a younger age. The findings, published today in the peer-reviewed journal Stroke, also found that compared to women with one uncomplicated pregnancy, a woman who had two or more pregnancies impacted by an adverse pregnancy outcome had a twofold higher increase of stroke. “We understand from past studies in the U.S. that women have a greater risk of experiencing a stroke and a disproportionate ...
