5G and Me: And Manufacturing

first_imgHow can 5G accelerate manufacturing?With its increased speed, higher bandwidth and lower latency, fifth-generation wireless cellular technology, or 5G, has the potential to be a key enabler and accelerator of the next generation of smart manufacturing. Some advantages of this communications technology for industrial applications include:Higher Bandwidth – modern IIoT gateways and distributed edge compute architectures are creating an explosion of valuable plant data and 5G networks are ideally suited to keep up with this data delugeLower Latency – allowing devices to communicate more quickly and reliably is especially important for machine-to-machine communications to function effectivelyGreater Device Density – 5G has the potential to connect to more devices, up to 1 million per km2, critical for a factory full of sensorsDevice self-registration – time and costs associated with deployment, setup and commissioning will be greatly reducedIncreased Security – cellular networks are more difficult to hack than standard WiFi implementationsFewer Cells – cellular signals can travel farther than WiFi, requiring fewer cells vs access points in an equivalent networkLower Power – the NR (New Radio) specifications have the potential to reduce power consumption by up to 100xWhen will 5G accelerate manufacturing?But the ultimate future of widespread 5G deployments in factories is not necessarily a foregone conclusion. Initial investments in acquiring private spectrum, purchasing hardware and the associated costs with learning and managing a new technology will be significant, especially in the early stages. It will require a total workforce transformation.And while the initial rollout of 5G will be focused on an enhanced mobile broadband (eMMB) experience – mostly targeted at cell phones and tablets, the IIoT enhancements necessary for manufacturing deployments are not scheduled for the next “R-16” release. This includes the ability to use unlicensed spectrum, machine communication protocols (like eMTC enhanced machine-type communication and NB-IoT narrowband Internet of Things) and the lower latency improvements (eURLLC enhanced Ultra-Reliable Low-Latency Communication) will not be available until late 2021. And the enhancements to the 5G radio for low power sensors and wearables is not expected until mid-2023. The transition to 5G is truly a journey and will not happen overnight.Scheduled Availability of 5G IIoT CapabilitiesWhat about technology we already have?Standard WiFi is not going away either. Newer technologies are on the horizon, offering improvements over existing wireless infrastructures. Following the well-known 802.11ac WiFi standard, the next generation will technically be 802.11ax, but will be known as WiFi 6. WiFi 6 will be up to four times faster in device-dense areas and offer much greater bandwidth than its predecessor.There is no shortage of interest and excitement around 5G for manufacturing, but the debate on its advantages vs WiFi will only intensify as the next generation WiFi 6 is released. Ultimately the market will decide which is the preferred technology to use, and most likely it will be a hybrid combination of the two. In any case, smart manufacturers know that this next generation of wireless connectivity will be enabled and accelerated by a modern infrastructure that includes distributed compute architectures to support the significant data streams being created.No matter the direction, Dell Technologies can help with the transition to whatever the wireless connectivity future holds. Enabling the transformational business outcomes promised by the IIoT will require a next generation digital infrastructure that only the Dell Technologies portfolio of companies and solutions can provide to build a truly integrated, converged, future-proof solution for all industrial customers.last_img read more

More avian flu feared near site of Indonesian family cases

first_imgAug 2, 2006 (CIDRAP News) – Seven people in Karo district of North Sumatra, Indonesia, are being treated for suspected H5N1 avian influenza, raising concern that the disease may have resurfaced near where human-to-human transmission was documented in an extended family in May.The Associated Press (AP) reported today that Indonesian health officials said the suspected cases fall into two clusters, one involving two sisters and the other consisting of three family members and two of their neighbors.Three of the patients are children who are believed to have been infected by chickens, the AP reported. The children include 10- and 6-year-old sisters and an 18-month-old boy who is their neighbor. Reuters news service reported today that the children were hospitalized yesterday.Blood samples were taken from the patients when they were admitted to Adam Malik hospital in Medan, health ministry official Hariadi Wibisono told the AP. Tests have not yet confirmed the H5N1 infection, but the patients are being treated as if they have the disease. Luhur Soeroso, who is treating the patients, told the AP that the seven patients have fever, cough, and other symptoms that have been associated with avian flu.In the North Sumatra case cluster in May, seven of eight family members tested positive for H5N1 avian flu, and only one family member survived. The cluster, believed to be the largest to date, marked the first documented instance of person-to-person transmission and the first three-person chain of infection, the World Health Organization said in June. Person-to-person transmission has been listed as possible or likely in several other case clusters.Indonesia’s official avian flu toll is 54 cases with 42 deaths, which ties it with Vietnam for the most deaths. All of Indonesia’s human H5N1 cases have occurred since mid-2005.Elsewhere in Indonesia, animal health officials on the resort island of Bali said hundreds of dead chickens have tested positive for H5N1 infection, according to an AP report yesterday. Health official I Gusti Hgurah Sandjaja said the outbreak involved 300 chickens, with no indications of any human cases. The AP report said health workers culled a large number of ducks and chickens on Bali earlier this year after several birds became ill.In Thailand, avian flu outbreaks seem to be spreading south, as evidenced by suspicious deaths of chickens in Lop Buri province in the lower central region, according to a report today in The Nation, a Thai newspaper. A 61-year-old woman in the province fell ill with avian flu–like symptoms after her backyard chickens died, said the report. The woman was admitted yesterday to Ban Mi Hospital, where a preliminary avian flu test came back positive, the newspaper said. Confirmatory tests are pending.According to a Web site of the Thai Ministry of Health, 144 patients from 24 provinces, mostly in the north, were on a watch list for avian flu as of yesterday.See also: Jun 23 CIDRAP News article “H5N1 mutation showed human transmission in Indonesia”last_img read more
