Communications Technology

Connectivity is a key feature of modern embedded products. There’s a wide range of communications modes that can be used, but which is the best for your design? Should you use a wireless technology such as Wi-Fi or Bluetooth and, if so, which one should that be? Or would wired communication, such as Ethernet, be the best way forward?

In this section, New Electronics reviews the latest communications technologies and brings visitors to the website information on how these technologies are being applied.

Which protocols will succeed in the IIoT?

The Industrial Internet of Things (IIoT) promises to support a new era of smart industry. Founded on the notions of openness and interoperability, easy scalability and ‘Big Data’, it can help enterprises drive significant operational improvements across their various manufacturing and business processes.

Bluetooth turns 20

In January 2018, the Bluetooth Special Interest Group (SIG) celebrated its 20th anniversary. Formed in 1998, the group was started with just a handful of companies who were looking to replace wire for mobile voice and data. Today, membership stands at more than 33,000 companies.

RS-485 transceivers need protection against large over-voltages

Robustness and reliability have made RS-485 an industrial workhorse. A minimum differential signal swing of 1.5V and reliable operation over common-mode voltages ranging from -7V to +12V have catapulted its deployment. Initially used as a communication network in laboratory instrumentation, RS-485 can be found in applications ranging from building automation to traffic monitoring systems.

Network transformation

Of all the new semiconductor device technologies that have been introduced over the past few years, gallium nitride (GaN) is arguably generating the most far-reaching effect across a number of different applications areas.

Living on the Edge

As the deployment of Industrial IoT systems continues to proliferate, the streams of data transferred to the cloud skyrockets, drastically increasing the cost for cloud computing.

Research excellence

Set up in 1956 Roke Manor Research has over the past 60 years established itself as a world-class electronics engineering consultancy.

It’s the little things

It’s not that many years ago that MEMS devices were regarded as something of a novelty, with early applications focused mainly in the automotive industry – airbag deployment, for example.

Close to the edge

There is a tension that lies at the heart of the software defined network (SDN). Telecom and datacom operators have seized on it because the idea of software-based control makes everything more flexible and it is only natural that demand for more responsive communications services should push technology in that direction.

Securing V2X communications

Test drive any new car and you’ll discover the automotive industry is in the middle of a connected car revolution. From rear view cameras and blind spot detectors to adaptive cruise control and lane assist, an unprecedented amount of electronics is being added each year in the name of improving safety and the driving experience.

Managing standards

With over 860 members the European Telecommunications Standards Institute (ETSI) produces globally applicable standards for a broad range of information and communications technologies, from fixed, mobile and radio to broadcast and Internet technologies.

The marine revolution

The global shipping industry has witnessed a series of revolutions over the past 150 years, including the transition from sail to steam and the advent of containerisation in the 1960s.

New challenges, new solutions

Today, it is a given that businesses are embracing the possibilities that the IoT can bring, whether that’s collecting data, using data analytics or developing and providing new services or improving existing ones.

The glue in the middle

In July 2017, the UK Electronics Skills Foundation (UKESF) met with partner universities and companies to celebrate and look back on the five years since its first cohort of scholars graduated in 2012.

Ensuring soldier welfare

From rifles that can track targets to providing battlefield monitoring via augmented reality, the military is seriously engaging with wearable technology to help improve its capabilities.

Timing gets smart

Ethernet has come a long way since IEEE 802.3 was first published in 1980. First envisioned as a technology to connect PCs and workstations, it has gradually evolved to become the networking technology of choice for a broad range of applications across enterprise computing, data centre, wireless networks, telecommunications and industrial sectors.

Material advantages

Photonics and its subset optoelectronics is, like electronics a relatively young technology. Interest in the area started to grow in the early 1960s, with the development of the laser, but photonics really started to boom in the late 1970s as fibre optic communications came onto the scene.
