Technology Filtered by - RF & Microwave

New Electronics strives to bring you all the latest technology news from the RF & Microwave sector. Advances in electronics are often fast-paced and innovative, so we know that as a design engineer you want to be kept up-to-date with current developments.

Below is a comprehensive list of all the latest electronics technology news from New Electronics.

Simplifying design while increasing bandwidth

In modern communications systems, the more bandwidth that is available, the more information that can be transmitted. As bandwidth requirements increase, the need for faster and higher linearity A/D converters and amplifiers also increases.

How plateauing clock speeds and increased data rates are changing test and measurement

A large misconception is that test data is purely pass/fail, but in reality this could not be further from the truth. The approach of traditional, fixed-functionality instruments is to send only the results back to the host PC of a test system. This results in much of the signal processing being hidden from the user within the box of the instrumentation. The speed of this signal processing is determined by the speed of the processor on board the instrument.

Verification of RF performance using simple tools and test setups

Buzzwords like Industry 4.0, the IoT, Mobile Computing, and Cloud Computing can be found in many headlines in magazines. The common theme throughout is the development and rapid expansion of modern communication technologies rooted in RF communication. Wireless connectivity is everywhere you look: in the warehouse, the office, the car, at home, at sporting events, and in medical technology.

High speed rail services pose wireless connectivity problems

Railway operators around the world are embracing wireless technology to help improve levels of security, raise levels of reliability, boost operating efficiency and enhance the consumer experience, whether that's by providing on board Wi-Fi access, better passenger information services or location based travel announcements.

Managing cell edge issues

Heterogeneous networks (HetNets) are now being deployed along with Self-Organising Networks (SON) to address the need for increased network capacity. A HetNet comprises a combination of macrocells or eNodeBs with small cells (microcells, picocells and femtocells) relay eNodeBs and remote radio heads (RRH).

How to make sure the IoT is as secure as it should be

Attacks on Sony and Target suggest current enterprise security, in many companies, is not fit for purpose. The Internet of Things means that almost anything can now be connected to the Internet, but that also means that anything connected to the Internet can be hacked. Most of the information isn't transmitted securely and many apps have vulnerabilities that can be easily exploited by anyone with the necessary skills.

Could 'Supercomputing at the Edge' provide a scalable platform for new mobile services?

Imagine a future in which every mobile base station is capable of instantly processing data as it is being uploaded or downloaded; where some types of data may be hugely valuable for just a matter of seconds, but which don't have to be stored in or sent to the cloud; or of a computing platform, located at the very edge of the network, where data is collected and the caching of content is done locally. All of these ideas are at the heart of the 'Supercomputing at the Edge' concept. For its proponents, it heralds a new age in big data management capable of supporting many new services and applications.

Connecting to the Internet just got even easier, says the Bluetooth SIG

For the IoT to work as envisioned, devices need to be connected to the Internet. This can be achieved with Bluetooth Smart devices, which can send data to a cloud service, but currently only through hub devices with full OS and supporting drivers running a software stack. For developers, being able to take advantage of direct connectivity to the Internet is a key requirement to take the IoT beyond the hype and create real 'always connected' experiences.

Camera pill technology set to ease cancer diagnosis

Colonoscopies can be an uncomfortable procedure for patients who may already be worried about what the results may find. The process involves probing the large intestine with a tiny fibre optic camera, known as an endoscope, embedded in a 4ft long, flexible tube.

Virtual solution could spell the end for antennas

The fast pace of evolution of the wireless industry puts familiar time-to-market pressure on the engineering of every new mobile device. Being in the heart of every mobile product, the design of the RF front-end and, in particular, the antenna, becomes especially cumbersome - every product currently requires a fully customised antenna.

Modulation approach set to solve spectrum congestion

As mobile communications become more pervasive, the amount of data flowing around the various networks and – importantly, the various parts of the spectrum – grows inexorably. The world, it is claimed, is moving ever closer to spectrum congestion.

UK researchers in race to develop 5G technology

Mobile device users in the UK are about to be offered mouth watering deals to entice them to shift to faster data rate services as competition finally comes to the 4G market. 02 has just launched its LTE based (Long Term Evolution) services, while Vodafone and 3G UK – the other operators with 4G licences – will follow on shortly as they try to make up ground on Everything Everywhere, which was allowed to use its 1800MHz spectrum last October.
