OPPO Research Institute releases new white paper on zero-power communication

Published

on

OPPO Research Institute officially released its new white paper on Zero-Power Communication. The paper examines the technical positioning of Zero-Power Communication technology in the context of current unmet demand in the IoT space while outlining a future roadmap for the technology to develop in coexistence with other communications systems of the future.

The majority of portable electronic devices today rely on batteries as their power source. While battery technology has come a long way over the years, current battery technology still presents significant problems in terms of the overall size, production cost, lifespan, ease of use, and environmental friendliness of the batteries themselves. Zero-Power Communication technology avoids the need for batteries by harvesting ambient radiofrequency energy in the environment to generate power, resulting in highly compact, efficient, and low-cost devices. Such properties have benefits in commercial applications such as warehousing, logistics, and agriculture and in wearable devices, smart homes, and other cutting-edge consumer applications.

“From the first to the fourth generations of mobile telecommunications technology, the telecommunications industry has gone through four technological leaps — from analog to digital, to data, and finally to broadband. Each of these leaps has been designed to deliver faster data transmission rates; however, over the next decade, looking at 5G technology and even further afield, we no longer believe that data transmission will be as big a driver in telecommunications technology. Instead, we believe that technology should evolve to deliver greater convenience and sustainable value for society as a whole. Zero-Power Communications technology offers a means for electronics manufacturers to remove batteries from their products, reducing their costs and environmental impact in the process. As such, Zero-Power Communications is one of our core focus areas as we move into the B5G/6G generation,” said Henry Tang, OPPO’s Chief 5G Scientist.

The current technology suffers from problems such as short communication distances, low efficiency, and small system capacity which presents significant challenges when applying RFID (Radio Frequency Identification) technology to specific or complex applications such as industrial sensor networks, low-cost and high-capacity logistics and warehousing, low-cost and low-power smart homes, and miniature wearable technology.

Unlike the traditional method, Zero-Power devices can harvest ambient radio signals broadcast from sources such as TV towers, FM radio towers, cellular base stations, and WiFi access points (APs) as their source of power. After harvesting the energy from existing radio waves, the device can modulate ambient radio signals with its own information and transmit these signals outwards in a process known as backscattering communication.

In addition to its own innovation, OPPO is also taking the lead in promoting the Zero-Power Communication standard, including proposing Zero-Power Communication research projects to 3GPP and presenting its findings during industry conferences such as FuTURE and ICCC. At the IMT-2030 6G Vision workshop in September 2021, OPPO initiated and organized a Zero-Power Communication Forum, inviting academic and industry organizations to discuss applications, technical requirements, and key technologies in Zero-Power Communication.

In line with its brand mission of ‘Technology for mankind, kindness for the world, ‘OPPO is targeting to release commercial Zero-Power Communication technology within the next 3 to 5 years as it continues to build smarter, more convenient, and greener communications systems.

Ninewells Hospital raises awareness on thyroid disease in newborns to commemorate World Thyroid Day 2022

Published

on

Ninewells Hospital, Sri Lanka’s leading woman and childcare hospital in the private sector, commemorates World Thyroid Day on 25th May by emphasising the significance of early detection and treatment of Congenital Hypothyroidism among newborns in Sri Lanka.

Congenital hypothyroidism (CHT) is a condition affecting infants from birth, and refers to an absent thyroid gland or a thyroid gland that is present but is unable to produce adequate thyroid hormones. On average, 1 in 4,000 babies are born with a severe form of CHT in Sri Lanka, while milder forms can be seen more commonly. If left untreated, the condition can affect brain development as well as normal growth in children and adolescents. Conversely, if detected and treated early, the damaging effects of CHT can be reversed and prevented completely.

“As Sri Lanka’s leading private sector childcare health service provider, we want to draw attention to the serious implications of Congenital Hypothyroidism on World Thyroid Day this year. Congenital Hypothyroidism is a condition which has a detrimental impact on postnatal development. For this reason, early detection and treatment is vital and should ideally begin within the first two weeks after birth,” said Dr. Vibash Wijeratne, Chief Operations Officer and Director, Ninewells Hospital.

In 2021 Ninewells Hospital unveiled a Thyroid-Stimulating Hormone (TSH) testing facility to support Sri Lanka’s national program for screening newborns for CHT and the country’s vision for a healthier population. Since then, the hospital has carried out over 8,000 tests in 2021 and over 2,000 tests between January and May of 2022.

With the unveiling, Ninewells Hospital became the first in the private sector to introduce a TSH screening machine and became one of the only two hospitals in the country to offer this screening service.

“The screening for CHT is a simple process that is performed using a heel prick test. At Ninewells, the test report following the screening is issued within a short span of three days which is unprecedented in the country. This allows healthcare providers to begin immediate treatment to avoid development impediments in newborns and infants,” Dr. Wijeratne also said.

Ninewells Hospital is Sri Lanka’s premier women’s and children’s hospital in the private sector, providing a variety of specialty services such as Obstetrics, Gynaecology, Paediatrics, and Fertility. The hospital, which is backed by the Access Group of Companies’ visionary leadership, continues to push boundaries and raise the bar for women’s and children’s healthcare in Sri Lanka.

SL plunges into worst economic contraction in the wake of dramatic currency collapse – CBSL Governor

Published

By Hiran H.Senewiratne

Sri Lanka will witness the worst economic contraction in its history, as it reels from a currency collapse of the rupee from 200 to 370 to the US dollar and interest rates contracted above 20 per cent, Central Bank Governor Dr. Nandalal Weerasinghe said.

“Sri Lanka is going through severe fuel shortages and power cuts after the credibility of a soft-peg was broken by mis-targeted interest rates in the course of targeting an output gap (printing money to boost growth) under the Keynesian ideology, Weerasinghe said while addressing the Press Club of the Sri Lanka Press Institute. The event was held at the Colombo Hilton on Monday.

Weerasinghe added: “At this juncture we cannot make normal imports for the next three to six months. Industries are saying there is no raw material. Only essential imports can be made on a priority basis in order to maintain day- to- day activities.

‘Sri Lanka’s economy contracted 3.6 per cent in 2020 amid the Coronavirus crisis and it also contracted 1.5 per cent in 2001, after a soft-peg crisis amid a civil war.

‘The latest failure of the unstable peg with the US dollar came after the Central Bank printed over two trillion rupees over two years to mis-target interest rates, leading to a steep collapse of the currency and a correction of the interest rates back to around 20 to 25 per cent.

‘The economic crisis has also spilled over into a political crisis and social unrest.

‘The rupee’s 2022 fall to 380 to the US dollar from 200 to the dollar is the worst currency crisis created by the soft-pegged Central Bank in its 72- year- old history.

‘The money printing Central Bank created its first economic crisis and output shock in 1953, bringing down growth to 0.7 per cent after triggering a now famous “hartal”.

‘An Exchange Control Act was also enacted in 1952 as the printed money from the newly set up Central Bank scrambled to go out, in a phenomenon that was repeated multiple times over the next 70 years and dragged the country into 16 IMF programs.

‘The unstable Central Bank was set up by a US money doctor in 1950 in the style of Argentina’s BCRA, abolishing a Currency Board that had kept the country stable through two World Wars and the Great Depression, where money printing above the external anchor was outlawed.

‘The worst recorded crises in the country include the 1948 uprising against the then colonial administration which took place after the British railway bubble burst, commodity prices fell and the then colonial government upped taxes. However, there is no information on the economic contraction that year.

‘Sri Lanka’s citizens burnt the houses and property of the elected ruling class on May 9, after the unstable peg collapsed in a botched float where interest rates were not allowed to go up before the float and a surrender rule pushed the rupee down.

‘Interest rates were allowed to go up after my appointment as CBSL Governor and the economy is now slowing and the headlong crash of the rupee peg has slowed.’
