Tech Focus: C-V2X Certification – Necessary or Just Nice to Have?

Monday, November 22nd, 2021

Fewer accidents and greater road safety are central to the vision for automated vehicles (AVs). Enabling that vision requires greater situational awareness and the ability to inform the car and its drivers what is happening a mile in front of them, foreseeing what’s likely to happen next, and automatically taking preemptive actions.

In this guest commentary, Cheryl Ajluni from Keysight Technologies shares her insights into C-V2X certification.

Cellular vehicle-to-everything (C-V2X) technology provides see-through, 360-degree, non-line-of-sight (NLOS) sensing in good, as well as adverse weather conditions to enhance the functionality and safety of autonomous driving (see the cover illustration).

C-V2X complements line-of-sight (LOS) sensors such as radar, lidar, camera, with information beyond their reach, and allows the vehicle to make more informed and coordinated decisions.

Whereas LOS sensors cannot indicate vehicle or driver intent, C-V2X conveys intent by sharing sensor data – resulting in a higher level of predictability in traffic situations such as lane changes, variable speeds, or road hazards.

Day one use cases include safety features such as emergency electronic brake light and forward collision warning, ‘do not pass’ warning, blind spot and lane change warning, vulnerable road user, road works warning, and intersection movement assistance.

Tech Focus: The Electric Vehicle Race to Market

Friday, October 29th, 2021

Three rapidly advancing technologies are driving this collective race towards zero-emission e-mobility: wide-bandgap (WBG) devices, more power-dense batteries, and faster charging capabilities.

In this guest commentary, Hwee Yng Yeo from Keysight Technologies shares her insights into the great EV race.

Since its inception on a paper napkin more than a decade ago, Formula E has evolved rapidly as a motorsport with a mission.

Entertainment aside, this electric streetcar racing’s founding mission is to showcase sustainable mobility to the world, and it has done pretty well.

It’s the only motorsport to have ISO 20121 certification for net zero carbon footprint since its first race in Shanghai in 2014.

Getting the Formula E car into pole-position entails a lot of hardware and software technology to extract maximum efficiency from the electric vehicle’s (EV) powertrain and battery.

For the key automotive OEMs, it’s not just about getting their car across the checkered flag first.

With billions of R&D dollars poured into developing better EVs, the goal of participating automakers goes beyond the championship trophy.

Learnings from these high-intensity races are applied to improve electromobility technologies back in the R&D labs.

Three rapidly advancing technologies are driving this collective race towards zero-emission e-mobility:

  1. wide-bandgap (WBG) devices
  2. more power-dense batteries
  3. faster charging capabilities

Efficient power conversion with WBG devices

A lot of power conversion takes place in the EV.

A DC-DC converter for example, steps down the power from the high-voltage EV battery to 12 V, with further conversions to run onboard systems like lighting, radio, and air-conditioning (see the diagram above).

WBG devices such as Silicon carbide (SiC) and Gallium nitride (GaN) semiconductors are used in transistors to facilitate this power conversion throughout the vehicle.

GaN applications are an emerging technology area, and developers find it hard to validate their design for these high-performance power converters.

Increased frequency and higher power affect the reliability of measurements needed to characterise the device’s performance.

It can be hard to distinguish whether the measured signal is the device’s characteristic or caused by the measurement setup.

Tech Focus: Signify Lighting the Fast Lane to IoT

Friday, September 10th, 2021

IoT – or the Internet of Things – has been the buzzword for a while now and businesses are constantly on the lookout for ways to fast track their IoT adoptions and rollouts.

I spoke with Jitender Khurana to find out how a traditional lighting network can be harnessed to rapidly transform a dumb building into a smart IoT-enabled environment.

I asked Jitender the key to Signify’s competitive advantage in helping its customers embrace IoT.

Three simple words: “Lighting is ubiquitous,” says Jitender, head honcho for Singapore and Emerging Markets at Signify.

Lighting is ubiquitous,” says Jitender Khurana, head honcho for Singapore and Emerging Markets at Signify.

But how does that give Signify a leg up in helping businesses embrace IoT more quickly and easily?

Well, the most tedious aspect of rolling out an IoT implementation is typically the deployment of IoT sensors and the network connecting these sensors back to the IoT platform.

Laying the network for both power supply and data tends to be both costly and time-consuming.

For Signify – that network is simply the lighting network that forms the basic infrastructure of any building or facility.

As far as the world leader in lighting is concerned, “Where there’s light(ing), there can be an IoT sensor integrated into the luminaire”.

Review: Philips Hue Outdoor Lightstrip to Liven Up Your Home

Monday, September 6th, 2021

Having had to #WorkFromHome for the past year, I decided to liven up the garden with a Philips Hue Lightstrip (Outdoor). It was a fun little project that was quick and easy to set up.

I got myself the 5m version of the Philips Hue Outdoor Lightstrip.

I got myself the 5m version of the Philips Hue Outdoor Lightstrip.

The Philips Hue Outdoor Lightstrip is a flexible, weatherproof LED strip that can be bent and shaped to produce your own lighting designs and mood in your garden or patio.

You can also use it indoors although there is a cheaper version (Lightstrip Plus) for indoor usage that’s not weatherproof..

With its diffused glow, the lightstrip can be used for direct or indirect lighting, and is able to display 16 million colour and 50 shades of gray all shades of white to create your personalised desired effect.

In the box is the lightstrip itself, the weatherproof power supply for plugging into the mains outdoors, as well as clips and screws to fasten the lightstrip onto the ground or wall based on the design you want to shape it to.

The lightstrip itself is quite flexible so if you’re just laying the lightstrip on the ground, I found that I could shape it without using any clips.

The lightstrip comes in 2m (S$209) and 5m (S$339) versions and is part of the Philips Hue line of intelligent lighting products for the home.

#tech4WorkFromHome: Turbocharge Home Wi-Fi with Linksys E9450 WiFi6 EasyMesh Router

Tuesday, June 1st, 2021

Want to improve the quality, speed and coverage of your home Wi-Fi for #WorkFromHome and #HomeBasedLearning? I’ve been using the E9450 WiFi6 EasyMesh Router from Linksys since its launch half a year ago and I’m very happy that it has delivered.

The Linksys E9450 Dual Band WiFi 6 Mesh router to expand Wi-Fi coverage and performance for #WorkFromHome and #HomeBasedLearning, as well as for gaming.

The Linksys E9450 Dual Band WiFi 6 Mesh router to expand Wi-Fi coverage and performance for #WorkFromHome and #HomeBasedLearning, as well as for gaming.

I’ve been using a telco-provided router for years – it has served me well although it could not reach the study, the bedrooms and the garden outside – so Internet access has always been confined to the kitchen, living and dining rooms.

Beyond the reaches of the old router, we had to switch on the mobile data connections on our handphones and hotspot the data to devices (speakers and computers etc) without a mobile data connection.

You can imagine how frustrating and limiting (and expensive) that can be.

And as the number of Internet-lusting devices being used in the household began growing rapidly, connection quality began to deteriorate, with slow speeds and dropped connections occurring more frequently.

Which was why I decided to upgrade the old router with the Linksys E9450 WiFi6 EasyMesh Router.

To expand the coverage of my home Wi-Fi network, I deployed a 2-node (1 parent + 1 child node) mesh network.

This was because a single-node network provided roughly a similar spatial network as my old router, probably because it was a matter of physical topology due to the layout.

The optical network terminal (ONT) for Singtel’s fibre optic network is located at one end of my apartment near the main entrance – instead of the center of the entire apartment – hence the distance between the router (which is connected by wire to the ONT) and the bedrooms tend to render the Wi-Fi signals too weak for connection.

I have a Network Attached Storage (NAS) connected (by wire) to the E9450 so that devices can upload/download files/photos and stream music/videos wirelessly via the Wi-Fi network. Another reason why I need a good Wi-Fi network with reach and performance.

So with a second E9450 router placed at the far end of the living room, the coverage of the Wi-Fi network was successfully extended to every bedroom – because the second router was located at the center of the entire apartment.

Tech Focus: Artificial Intelligence Consumes Energy Too

Wednesday, May 19th, 2021

Jo De Boeck notes the growing list of Artificial Intelligence (AI) applications as they take up more and more of the resources on Earth to deliver anything from Amazon recommendations to deciphering a virus DNA.

In this guest blog, the EVP/CSO of imec shares his insights into how power-hungry AI can be and the need for an Energy label for AI.

AI has become more intelligent in recent years.

Fuelled by seemingly infinite computational power that is easily available on tap today, it now processes huge amounts of data to recognise patterns every day.

Yet, with each new “trick” that an AI can learn, whether this is differentiating a cat from a dog or getting a robotic arm to figure out a Rubik’s Cube, billions of calculations go into each task.

“We need to talk about an Energy Label for AI,” says Jo De Boeck, EVP & CSO, imec. Photo: imec.

“We need to talk about an Energy Label for AI,” says Jo De Boeck, EVP & CSO, imec. Photo: imec.

That takes a lot of energy to power up, adding to an already fraught situation with global warming.

Compare this to the human brain.

It can effortlessly complete many of these cognitive feats that AI is accomplishing and celebrated for today, while requiring a small fraction of the energy.

So, while AI can be useful to help save energy by optimising its use, there is energy needed to train an AI model as well. This energy is not insubstantial.

Can this inspire us to develop more energy-efficient AI systems?

Will they bring a net positive in efforts to prevent or reverse permanent environmental damage?

Study: 45% of Singapore SMBs Want to go 100% Laptop Post COVID-19

Friday, March 12th, 2021

In an IDC survey commissioned by ASUS, SMBs are more inclined to equip their employees with laptops rather than desktop computers – compared to prior to COVID-19.

Hmm, still somewhat behind Japan I suppose. I recall, when attending a senior management & leadership course in Japan in the late 90’s, the staff at the college were already equipped 100% with laptops, while fellow-attendees of the year-long course were issued with a personal laptop. It was a cultural mindshift - coming from a work environment at home when it was still 100% desktop.

Presented during the IDC & ASUS Webcast 2021 Singapore – Digital Transformation for the Next Normal in Asia/Pacific, ASUS revealed that 45% of Singapore SMBs are likely to convert to a 100% laptop setup post COVID-19, underscoring the importance of mobility in a hybrid workplace model.

The finding is among other strategic insights to SMB technology use and how COVID-19 has affected related decisions.

Three suggestions from IDC that Singapore SMBs can implement with regard to technology implementation.
