What is the Z-Wave protocol?

Z-Wave-Technology

EE World – Smart homes need wireless connectivity, and Z-wave has emerged as the ultimate solution for home automation. The Z-wave protocol is a wireless, radio frequency protocol designed primarily for smart home networks. All the existing wireless communication protocols had one or the other problem. Bluetooth and Zigbee often shortfall of range while Wi-Fi poses its own limitations in a low-power ecosystem. Interoperability has been another major issue as popular wireless standards have different protocols and implementations for different applications. No one solution could cater to the requirements of an automated home. Z-wave is, now, the solution for all those lingering issues.

Z-wave devices are interoperable and can be easily accessed through the internet or a Z-wave gateway. With a range of around 40 meters, a Z-wave network limited to four hops can connect at most 232 devices. Irrespective of their make or application, all devices can have simultaneous two-way communication over the Z-wave network secured using AES. With sufficient range, optimum data speed, AES security, low-power wireless solution, and interoperable protocol, Z-wave is just perfect for home automation. There are now thousands of Z-wave products in the market, serving as intelligent devices for smart home ecosystems.

Major Advances with Motor Control Centers (MCCs)

Motor Control Center
MCCs are most widely used in the utilities, manufacturing, industrial, and large commercial industries that operate machinery and motors. MCCs offer enormous flexibility across differing industries and are suitable for many applications, such as: utilities, communications, oil, gas, chemical, pulp, paper, water, waste, mining, metals, industrial production, and mass-production manufacturing. MCCs are used to house various power distribution equipment and controls such as: main distribution panels (MDPs), main circuit breakers (MCBs), protective relaying, transformers, load centers, panelboards, etc.

Why The Healthcare Sector Must Demand Real Cybersecurity Change

Cyber-threats-to-healthcare

Forbes – Managing Director of Technology at Health2047 with a comprehensive understanding of the digital transformation of health care IT. We should be outraged and deserve better. 

In late October of this year, a joint cybersecurity advisory from the U.S. Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the Department of Health and Human Services (HHS) warned of an uptick in ransomware activity targeting the healthcare and public health (HPH) sector, specifically hospitals and healthcare providers.

The advisory came just over a month after reports out of Germany documented the first patient death directly tied to a hospital ransomware attack. That’s right: The healthcare cybersecurity situation has now become a matter of life and death.

Healthcare cybercrime such as ransomware is especially egregious during a pandemic, as illustrated by Bitdefender data (via Security Boulevard). But it is now sadly all too commonplace. Also far too commonplace is the seeming inattention and inaction in the face of rising threats.

Major Solar Storms That Could Effect the Earth

Solar-Storms

Washington Post – After a lengthy slumber, the sun is waking up, crackling with activity and hurling blistering pulses of energy into space. Solar physicists are expecting an uptick in stormy “space weather,” with implications that affect us here on Earth.

As soon as Thursday, the National Oceanic and Atmospheric Administration is predicting that a solar outburst could generate northern lights or aurora as far south as Oregon to Pennsylvania.

This flare-up coincides with the onset of “Solar Cycle 25,” an 11-year window within which storminess on the surface of the sun peaks and “solar storms” become routine.

The sun is nearly 93 million miles away, but disturbances on its surface can have serious effects far and wide across the solar system. Solar scientists and forecasters of space weather track “sunspots,” or cool, discolored regions that make appearances on the solar disk. The number of sunspots present at any given time fluctuates over the course of 11 years, each span representing one cycle.

Sunspots are often the source of solar flares, which can cause high-frequency radio blackouts and interrupt communications on Earth. At the same time, sunspots may also release coronal mass ejections, which are sneeze-like eruptions of magnetic energy, that can bring about occasionally epic displays of the northern lights.

Responding to the FCC’s 900 MHz Transition Order

FCC-Telecommunications

T&D World – Hundreds of public, private and nonprofit entities in sectors including public utilities, municipals, cooperatives, manufacturing, transportation, and oil and gas have been utilizing narrowband land mobile radio (LMR) communications systems to enhance their operations for more than 30 years. Such organizations and others like specialized mobile radio (SMR) and business/industrial/land transportation (B/ILT) providers must have 900 MHz licenses which authorize their use of the airwaves. If you fall into one of these categories, you may be affected by the Federal Communication Commission’s (FCC) recent order to realign the 900 MHz band.

Learn more about the business-critical connectivity issues currently facing U.S. organizations in this FAQ.

What Makes 5G So Fast? – (All About Circuits)

Telecommunications-Speeds

(All About Circuits) – With 5G rolling out more quickly as we approach 2021, it may be helpful to touch on the key technologies that make 5G such a speedy success.

In a recent article, we discussed the basics of 5G technology—a discussion that is no longer in the realm of the hypothetical with 5G now being deployed in practice. One of the key talking points of 5G, at least from the consumer perspective, is its blazing-fast speeds. But what exactly makes 5G so fast? 

While the hardware-level details of 5G speed are extensive, this article will briefly discuss the basic building blocks that bump 5G speeds from 4G and LTE rates. 

As the name suggests, the 5G new radio (NR) requires a new kind of radio technology, antenna, and carrier tower design to achieve speeds of one gigabit per second with latency less than 10 milliseconds. The actual performance would depend on the design of the 5G products and the environment in which they operate.
