Maxim’s GMSL SerDes technology extends video transmission in vehicles

Tue, Jul 09, 2019

For video transmissions in vehicles, Maxim Integrated’s gigabit multimedia serial link (GMSL) serialiser and deserialiser (SerDes) technology is used by MediaTek in its Autus in-vehicle infotainment (IVI) platform.

MediaTek’s AUTUS I20 (MT2712) is a high-performance, hexa-core infotainment system and has a flexible interface to support multiple displays. It links drivers to their vehicles to improve the driving experience, passenger safety, connectivity and entertainment, providing information and content from the car’s sensors and multimedia sources.

Maxim’s advanced GMSL SerDes technology delivers robust video distribution for these surround-view applications, says the company. One MAX9286 automotive deserialiser and four MAX96705 serialisers provide synchronised video streams from four cameras via 15 meters of shielded twisted-pair (STP) or coaxial cable.

To support data transmission for auto sensors, entertainment content and navigation, designers required a higher-speed, higher-voltage memory technology. This was achieved using Maxim’s MAX20010 high-current, 6.0A buck converter with dynamic voltage scaling, reports Maxim. It enabled MediaTek to migrate to a higher voltage memory.

Maxim’s GMSL SerDes technology extends data transmission distance from 12 to 15 metres with the MAX9286, and also provides surround-view application support with a single chip via frame synchronisation on four input channels enabling higher system performance by offloading the SoC. Support for MIPI-CSI-2 output enables seamless interoperability with MediaTek’s SoC and spread-spectrum features reduce electromagnetic interference (EMI) to improve safety and performance.

The GMSL SerDes technology provides data integrity over 15 meters.

With dynamic voltage scaling (DVS), Maxim’s MAX20010 high-current buck converter allows Autus I20 designers to upgrade to fast, higher voltage 4Gbyte LPDDR4/DDR4 memory, for sufficient power to support multiple video-rich applications across in-car displays. Maxim’s buck converter also provides skip mode to save power consumption when the MediaTek IVI is running at light load.

Maxim Integrated develops analogue and mixed-signal products and technologies to make systems smaller and smarter, with enhanced security and increased energy efficiency. The company powers design innovation for customers in automotive, industrial, healthcare, mobile consumer, and cloud data centre markets.

Digital services uses secure IP technology to save workplace costs

Tue, Jul 09, 2019

Schneider Electric has developed a suite of digital services to convert traditional office buildings into smart, responsive workplaces of the future. The EcoStruxure Workplace Advisor uses real-time data from wireless sensors and other devices, to enable building managers to optimise space in flexible work environments, enhance occupant well-being, and efficiently manage facility services.

EcoStruxure is Schneider Electric’s open, interoperable, IoT-enabled system architecture and platform. It features essential analytics and services that fulfil needs in new or retrofit commercial office buildings. Its occupancy analytics allows users to quickly identify underutilised desks, offices, meeting rooms, and amenities for effective re-allocation. Building managers can rationalise space needs and change layouts to align with usage and evolving staff numbers. It lets employees see available spaces in real-time to support office hoteling.

Well-being analytics actively monitors temperature, humidity, CO², noise, light and volatile organic compound (VOC) levels. Users benefit from a proprietary Comfort Score that helps to proactively pinpoint spaces that have consistent comfort issues that impact occupants’ work environments.

Employee productivity can be helped with the geo-location and wayfinding feature. The mobile navigation app provides the location of colleagues, meeting spaces, desks, or other amenities. It also maintains digital floor plans so they are always up-to-date.

EcoStruxure Workplace Advisor is a cloud-based software as a service (SaaS) and will continuously respond to customer demands with additional functionality, including people analytics, asset tracking, and integration into other building systems such as reservations and ticketing.

EcoStruxure Workplace Advisor is flexible, scalable and future-ready for integration to address a wide range of changing customer needs, says Schneider Electric. It is based on a secure IP architecture from the sensor level to the cloud, to provide the highest quality data and level of scalability with best-in-class security, claims the company.

Schneider Electric operates in the digital transformation of energy management and automation in homes, buildings, data centres, infrastructure and industries. It is present in over 100 countries, and specialises in power management, medium voltage, low voltage and secure power and in automation systems.

Huber+Suhner says outdoor MIMO antennae will ease 5G in cities

Mon, Jul 08, 2019

Believed to be the first outdoor antenna that is omni-directional, Huber+Suhner have developed the SenCity Urban antenna. It adopts existing city infrastructure such as street furniture for widespread 4G and 5G deployment, says the company, to ease urban 5G deployment.

The compact omni-directional and directional outdoor antennae are for use where operators need to provide cost-effective 4G and 5G in urban areas. Small cells increase capacity and coverage in urban areas where networks are congested with growing numbers of wireless devices. However, creating new cellular sites in urban areas is challenging as only limited space is available for installation and may also face restrictions by municipal governments.

Huber+Suhner’s SenCity Urban 100 and 200 outdoor MIMO antennae cover both 4G and 5G high frequency ranges and can be installed in street furniture, such as bus shelters, poles or walls, using bracket mounting options.

Claudia Bartholdi, product manager at Huber+Suhner said: “At the moment there are no other antennae on the market that are as compact . . . that cover 4G and 5G bands”.

The SenCity Urban range is part of the 5G portfolio from Huber+Suhner and is available now.

OneM2M establishes standard for IoT interoperability

Tue, Jul 02, 2019

Laying the foundations of an interoperable, global internet of things (IoT) ecosystem, the Global Certification Forum (GCF) has announced the immediate availability of its oneM2M certification programme, following an official memorandum of understanding earlier this year with the Telecommunications Technology Association (TTA).

The standardisation body for machine to machine (M2M) and the IoT has over 200 partner members including global standards bodies and companies from the IT and telecomms sectors. It says that the advent of 5G and “the prolific growth of IoT connectivity, the oneM2M certification is critical to the standardisation of converging technologies from multiple industries, ensuring scalability, interoperability and security”.

“The launch of our global oneM2M certification programme today means that manufacturers of M2M devices will have access to a simplified interface for all their certification requirements,” said Lars Nielsen, CEO and general manager, Global Certification Forum. “Together with our 5G certification programme, we can now provide a suite of certification solutions for the smart connectivity space that will guarantee the sustained success of IoT deployment as it takes off.”

“The exponential growth of the M2M and IoT market can only succeed with standardisation, which is why we work with partners like GCF and TTA,” said Roland Hechwartner, technical plenary chair at oneM2M. “The availability of this GCF certification programme means a guarantee of seamless operability for developers who are building applications with data from multiple different sources or deploying devices that use a plethora of communication technologies,” he added.

The oneM2M certification from GCF can be applied for at http://onem2m.globalcertificationforum.org.

The Global Certification Forum was founded in 1999. It defines the certification requirements for the mobile industry by working closely with 3GPP, a global co-operation of independent standardisation committees, (ARIB, ATIS, CCSA, ETSI, TSDSI, TTA, TTC), that define specifications for wireless standards. It brings together around 140 of the world’s leading manufacturers, operators and the test industry.

oneM2M is the global standards initiative that covers requirements, architecture, API specifications, security solutions and interoperability for M2M and IoT technologies. The initiative was created in 2012 and consists of international standards development organisations: ARIB (Japan), ATIS (U.S.), CCSA (China), ETSI (Europe), TIA (U.S.), TSDSI (India), TTA (Korea), and TTC (Japan), together with industry consortia (CEN, CENELEC, GlobalPlatform, OMA SpecWorks) and over 200 member organisations.

oneM2M specifications provide a framework to support applications and services such as the smart grid, connected car, home automation, public safety, and health. oneM2M actively encourages industry associations and forums with specific application requirements to participate in oneM2M, in order to ensure that the solutions developed support their specific needs.
