ATIS Brings Open Source oneM2M Support to Embedded Cellular IoT Modules
ATIS today announced that it has successfully demonstrated a cellular IoT module using the ATIS OS-IoT software accessing cloud-based oneM2M standard services over Vodafone’s Open Lab Narrow-Band IoT (NB-IoT) test network. The global oneM2M standard defines a common, interoperable platform for IoT systems, providing application-independent building blocks that fulfill core tasks of secure data collection, management and distribution. The NB-IoT standard, defined by 3GPP, provides economical and efficient support of narrow-bandwidth communication services to IoT applications with wide geographic coverage by adding IoT optimizations to mobile cellular networks. The demonstration shows how applications built on the Open Source OS-IoT platform can use oneM2M and NB-IoT standards together to provide IoT capabilities suitable for global markets. “With OS-IoT, developers of sensor applications have an open platform that combines access to the oneM2M ecosystem with the international coverage and efficiency of NB-IoT communication,” said ATIS President and CEO, Susan Miller. “This platform enables application developers to expand their addressable market by offering oneM2M support on a wide range of sensor devices that meet tight cost and power constraints.” As the IoT revolution advances, a broad range of applications, including wearable devices, low-cost environmental monitors, smart meters and smart cities applications, depend on efficient machine-to-machine communication capabilities. NB-IoT allows cellular networks to overcome the challenge of providing connectivity to these devices and delivers communications services suitable for long-lived battery-powered sensors. The use of the oneM2M standard can help application providers address current concerns about IoT security, trustworthiness and data privacy while still providing openness where appropriate. The enhanced OS-IoT platform allows sensor applications to run directly on the NB-IoT cellular module without the need for an additional external microcontroller to act as an application processor. Compared to the conventional approach of using separate devices for the cellular module and the application processor, this reduces the Bill of Materials (BoM) costs of IoT sensors and offers lower power consumption. View the demonstration of the ATIS OS-IoT library for support of oneM2M running on the BG96 Cellular IoT module over Narrow-Band IoT (NB-IoT) at the Vodafone NB-IoT Open Lab here.

HID Global Helps Hospitals Keep Doctors, Nurses and Staff Safe from Workplace Violence with New IoT-Based Duress Badge
HID Global®, today announced its new BEEKsÔ Duress Badge Beacon that addresses the growing need to protect doctors, nurses and other caregivers from threatening situations that arise in the hospital environment. The Bluetooth Low Energy (BLE) duress functionality provides a fast and easy way for hospital personnel to send security staff real-time distress alerts from anywhere in or around the hospital campus if they are in duress and in case of other emergencies. Enabled by Bluvision™ (part of HID Global), the duress beacon is the latest addition to the HID Location Services IoT platform, which makes it possible to streamline and enable multiple location services applications in a unified healthcare IoT ecosystem. The BLE beacon can be used by itself or integrated into popular access control cards already in use. Staff members or clinicians just press the back of their badge to instantaneously trigger a duress alert that identifies them and their location—inside the hospital, the parking garage or other configured areas—for immediate action by security teams. “It’s well known that an effective response system is critical to keep high-risk situations from escalating into workplace violence, but acquiring, deploying and managing yet another disparate hospital system is costly–often creating a barrier to adopting a duress solution,” said John Sailer, Chief Operating Officer of Bluvision. “HID’s new beacon and our end-to-end IoT platform enable hospitals to easily plug real-time duress detection and alerts into their healthcare IoT infrastructure. This powerful combination simplifies the process of increasing healthcare personnel safety with a solution that also requires minimal effort by the user.” Together with HID Location Services, the new beacon can be centrally managed through the cloud to transfer new messages, send firmware updates and conduct battery status checks remotely. Its unique design allows it to broadcast reliably and with precision, even in densely populated Wi-Fi environments. The beacon simultaneously supports iBeacon (Apple), Eddystone (Google) and sBeacon (Bluvision) protocols and pinpoints the location of the user down to 6 ft (2 m). HID’s duress badge solution with real-time location services is highly sought after beyond healthcare. The hospitality market, including restaurants and hotels, is another broad area where staff is vulnerable to workplace violence risks due of the social nature of the sector. The hotel industry has been an early adopter of duress solutions to help their room attendants feel safe on the job.

Galvanic Isolation Secures New 48-volt Electrical Architectures
leading supplier for gigabit transceivers over POF (Plastic Optical Fiber) – provide their optical connectivity technology in order to secure new 48-volt electrical architectures via the inherent galvanic isolation. "The new 48-volt electrical architecture pushes the envelope in terms of electromagnetic compatibility and safety requirements," stated Carlos Pardo, CEO and Co-founder of KDPOF. "New safety precautions are needed, since even a single malfunction between the 48-volt and the 12-volt electrical system will lead to a short circuit, which can damage the entire 12-volt system due to overvoltage." Optical connections with POF, such as KDPOF's innovative Automotive Gigabit Ethernet POF (GEPOF), provide the optimal means to achieve galvanic isolation, providing 100 Mbps and 1 Gbps Ethernet compatible solutions with enough margin to withstand the harsh automotive environment. Applications such as Battery Management Systems (BMS) and Integrated Smart Antenna (ISA) modules profit from the inherent Electromagnetic Compatibility (EMC) of POF. KDPOF will present their GEPOF technology at the Automotive Ethernet Congress on February 13 and 14, 2019 in Munich, Germany. 48 Volts Generate Need for Galvanic Isolation The chassis is a common ground potential for all 48-volt ECUs in the car. As the chassis has a non-zero impedance, a significant return current will be conducted through it, and a portion of this return current will find its way through a parallel path: the copper cables‘ shielding. "An OEM has stated that the shield of Shielded Twisted Pair (STP) cables can conduct more than 8A of return current due to the 48-volt jump start effect," added Carlos Pardo. In addition, the need for a ubiquitous communications network within the vehicle, and particularly between ECUs belonging to different voltage domains, represents a source of potential hazards. Thus, it imposes the additional requirement of galvanic isolation between the communicating nodes. Any event that could cause the 48-volt to cross into the 12-volt, for example due to line transceivers that don’t provide sufficient galvanic isolation, might destroy the ECUs in the 12-volt domain. With regulations driving car companies to reduce Greenhouse Gas (GHG) emissions further by 2021, a new hybrid architecture concept based on a two-voltage power line (12-/48-volt) is already in the advanced marketing announcements of OEMs and Tier-1. As a further example of this new industry-wide technological trend towards 48V power supply and the handling of it, the German VDA published recommendation 320, which covers electric and electronic components in vehicles for the development of a 48-volt power supply. It defines requirements, test conditions and tests performed on electric, electronic and mechatronic components and systems for use in motor vehicles with a 48-volt on-board power supply. Battery Management Systems Galvanic isolation is also necessary between the primary and secondary systems of both ac-dc and dc-dc converters due to the presence of hazardous high voltage (above 25 Vac or 60 Vdc). According to the FMVSS 305 and ECE-R standards, the isolation barrier between the battery and exposed conductive parts should maintain 500 Ω/V before and after a crash impact. "This is a tough requirement that is very hard to reach without a nearly perfect isolation that copper-based networks are unable to ensure," added Carlos Pardo. Moreover, the BMS is a very noisy environment and communications are susceptible to disturbance by conducted and radiated RF emissions. Optical communications have been demonstrated to be the most robust regarding EMC. Smart Antenna Modules Integrated Smart Antenna (ISA) Modules consist of several antennas for signal reception, an Antenna Hub, and an Ethernet connection to the consumers of the antenna signals such as a radio device. If each of the several antennas in a car is routed to its respective ECU with its own cable, the complexity soon becomes unacceptable. The Antenna Hub routes all signals from each antenna to an Ethernet network connected to all receptors of the signals. Gigabit Ethernet over POF is ideally suited for an Ethernet connection due to its natural EMC-free property. "In conventional systems, if the roof is not metallic, or has openings, an immense amount of energy is radiated by the coaxial cable that is coupled back into the ISA. This seriously degrades the ISA performance," explained Carlos Pardo. Replacing the coaxial cable with POF completely solves this issue.

u-blox seeks fair, reasonable and non-discriminatory (FRAND) licensing terms
u-blox (SIX:UBXN), today announced that it has no choice but to file a lawsuit against Interdigital, Inc. in the United States District Court for Southern California in order to obtain a fair, reasonable and non‑discriminatory (FRAND) license to Interdigital’s patents. After two years of failed negotiations, despite its legal obligation to do so, Interdigital failed to offer u‑blox a FRAND license agreement covering the sale of u-blox 2G, 3G and 4G products. “u-blox respects the intellectual property rights of others and has always been and continues to be a willing licensee to standard essential patents (SEPs). It is how we do business”, said Thomas Seiler, CEO of u-blox. “We have therefore asked a court to review and determine the FRAND rate for the patents held by Interdigital. u-blox is a committed licensor for the benefit of our customers and we believe that our willingness to license also positively distinguishes u-blox within the module industry. To the extent that Interdigital is willing to reconsider their position, u-blox is open to further negotiations - but not to the detriment of the company, our customers or shareholders.” Concurrent to filing the lawsuit, u-blox has also asked the court for an immediate Temporary Restraining Order (TRO) and preliminary injunction against Interdigital to avoid any disruption to its existing business relationships.
