Technology Filtered by - Communications Hardware

New Electronics strives to bring you all the latest technology news from the Communications Hardware 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.

Connector to combat passive inter modulation on mobile networks

Passive inter modulation – PIM – is ‘unwanted interference’ which tends to occur when two or more interacting signals either interfere with one another or are affected by outside interference. While PIM is not new, the development of Long Term Evolution (LTE), 4G and 5G generation networks means that it has become more important as an issue. These networks have proven to be far more vulnerable to the effects of PIM, as well as to other signalling problems.

Fighting fibre with G.Fast broadband

Offering really high speed fixed broadband to all who need it would seem to mandate rolling out optical fibre to the customers’ premises, according to the industry and a number of operators and equipment manufacturers are trying to show this is true - but only up to a point. They point to a bewildering array of technology and economic options for upgrading broadband networks, with emerging standards and technologies targeting legacy ‘last mile’ copper connections.

Maximising the potential of fibre optic communications

The Electronic and Electrical Engineering department at University College London (UCL) has been linked almost inextricably with the development of the communications industry. Professor Polina Bayvel, head of UCL’s Optical Networks Group (ONG), pictured below, explained: “It’s a special department; the first electronic and electrical engineering department in any UK university.”

Communicating data in the IoT

The Internet of Things is evolving to provide greater intelligence at the node, converting raw data into smart information. With less data to communicate, it becomes more cost-effective to integrate low power RF transceivers into the node module. Certification to wireless protocol standards ensures interoperability and the emergence of open tools will make support for these standards less onerous to developers.

Enabling robust data communications within a high voltage BMS

The primary purpose of the battery management system (BMS) is achieving reliability, performance and longevity of battery packs. As part of this, the battery management electronics measures each cell voltage and transmits this information to a central processor. For high voltage battery strings – such as is typical for automotive drivetrains –a modular distributed pack is an attractive choice. Battery modules can serve as the basic building block for multiple pack designs. Modules also allow for optimal weight distribution and maximum use of available space. The biggest challenge is the datalink required to operate the pack as a single unit.

New technologies widen touchscreen opportunities

A quiet revolution is taking place in the projected capacitive touchscreen market. Rapid industry developments are delivering touchscreens which are thinner, higher performance, more reliable and lower cost. The impetus behind many of these developments is the fact that indium tin oxide (ITO), the long standing conductive material of choice for phone and tablet touchscreens, has limitations and consequently is being superseded by alternative materials. ITO has never been widely used in large format AV and kiosk applications, but some of the technologies that are being developed to replace it could.

Addressing the need for ultra-small ambient light sensors in wearable products

In today’s wearable health and fitness market, where consumer electronic backlight displays continue to get thinner, having an ambient light sensor (ALS) capable of being integrated into the thinnest backlight displays is becoming ever more important to designers of these devices. The proliferation of cell phones and the demand for a better user experience has driven a higher adoption rate of ALS in touchscreen smartphones. In these display management applications, automatically controlling the backlight intensity with an ALS ensures the best possible user experience while extending battery life.

Can optical technology solve the high performance computing energy conundrum?

In summer 2015, US president Barack Obama signed an order intended to provide the country with an exascale supercomputer by 2025. The machine would be 30 times more powerful than today’s leading system: China’s Tianhe-2. Based on extrapolations of existing electronic technology, such a machine would draw close to 0.5GW – the entire output of a typical nuclear plant. It brings into question the sustainability of continuing down the same path for gains in computing.

Boosting the health of UK manufacturing industry using photonics technology

One of the big themes being pursued by the recently elected Conservative Government is the revival of manufacturing as one way to reduce the country’s dependence on the financial and services sectors. While the UK’s manufacturing sector remains in the world’s top 10, it has been drifting down the league table since the 1970s and productivity has been of particular concern.
