Modems for GEO / GSO satellites provide uninterrupted monitoring

Mon, Jun 26, 2023

Modems developed by Qualcomm in collaboration with non-terrestrial network (NTN) service provider, Skylo to provide uninterrupted remote monitoring and asset tracking. They enable low power connectivity for IoT devices across satellite and cellular networks, said Qualcomm.

The modems follow the 3GPP Release 17 standards for satellite communications on GEO / GSO (geosynchronous equatorial orbit / geostationary orbit) satellites, making connectivity available globally and providing easy device set up and orientation.

Both chipsets support the Qualcomm Aware platform, which provides real time asset tracking and device management in remote areas to support critical decision making.

Qualcomm Technologies has announced the Qualcomm 212S and the Qualcomm 9205S modem chipsets with satellite capability. They power off-grid industrial use cases that require standalone non-terrestrial network (NTN) connectivity or hybrid connectivity alongside terrestrial networks, and allow IoT enterprises, developers, ODMs and OEMs to harness real time information and insights to manage business projects.

The Qualcomm Aware platform allows companies to better monitor and track valuable assets virtually anytime and anywhere around the world. The 212S and 9205S chips advance IoT tracking and monitoring capabilities to provide connectivity and coverage even in the most remote areas, said Qualcomm.

It is designed with ultra-low power consumption for applications in remote, fixed locations, helping promote an extended usable life. Applications include gathering telemetry and data from water and gas tanks, meters, and other infrastructure equipment. It is also suitable for utility grid monitoring, early fire detection reporting, on-shore and off-shore mining installations, and environmental management.

The Qualcomm 212S is Qualcomm Technologies’ first IoT-NTN-only modem that supports the 3GPP Release 17 standards for satellite communications. It is designed for cost efficiency and value, with only the essentials necessary for satellite communications and nothing more, added Qualcomm.

The Qualcomm 212S is also compatible with the recently announced Qualcomm QCM4490 processor to deliver low power satellite connectivity to industrial handheld devices. This important integration powers time-critical, two-way messaging capabilities and one-way payload delivery between devices and customer end points or the Qualcomm Aware cloud, all while helping promote extended usable device time.

The Qualcomm 9205S modem chipset enables IoT devices to easily connect to cellular and satellite networks for virtually gap-free coverage, and integrates GNSS to provide location data.

It is suitable for industrial applications that require always-on, hybrid terrestrial and satellite connectivity for goods and assets on the move. Applications include transoceanic shipping container tracking, agricultural equipment and livestock tracking, global fleet and freight tracking for supply chain management including for logistics partners that perform remote deliveries.

The Qualcomm 9205S uses virtually the same architecture as the Qualcomm 9205 modem, making it easy to upgrade equipment designs to include satellite connectivity and enable hybrid connectivity. The Qualcomm 9205S helps enable hub-type use cases through a highly capable applications processor and peripheral support for a wide variety of IoT applications.

Like the Qualcomm 212S, the Qualcomm 9205S adheres to 3GPP Release 17 standards for satellite communications, making it easy to establish IoT-NTN connectivity using GEO/GSO satellites and eliminates the need for orientation-specific device positioning.

The Qualcomm 212S modem will be available later this year and Qualcomm 9205S modem is available now.

Thermal stable IMU expands TDK’s SmartIndustrial family

Fri, Jun 23, 2023

A thermal stable IMU (inertial measurement unit) for tilt and stabilisation applications extend TDK’s SmartIndustrial family.

The IIM-20670 is a robust, six-axis IMU with extended temperature range and high VRE (vibration rectification error) performance, said TDK. It joins TDK’s family of three-axis accelerometers and a three-axis MEMS IMU supplementing InvenSense SmartIndustrial product line

The IIM-20670 features a robust monolithic six-axis IMU, three-axis accelerometer and three-axis gyroscope, with proven shock robustness and capability to simultaneously measure all the six axes with a current consumption below 10mA under all operating conditions. With its support for extended temperature range of -40 to 105 degrees C, this new six-axis IMU targets industrial applications that requires extreme stability over temperature and great vibration immunity.

The IIM-20670 is calibrated over multiple temperature points and available in a compact QFN 4.5 x 4.5 x 1.1mm³ form. The package has wettable flanks that simplify inspection at the end of the assembly line, added TDK. The IMU also features programmable digital filters and a 10MHz SPI where data integrity can be assessed by a CRC-based error-detecting code algorithm. The IIM-20670 contains an accelerometer thermal stability of 45 microg per degree C, an accelerometer bias repeatability of 1mg and a programmable output of 64G alongside a tilt algorithm that outputs pitch and roll data over the full temperature range.

Modular two-port vector network analyser can measure up to 100m

Tue, Jun 20, 2023

Vector network analysers (VNAs) from Anritsu offer performance and cost advantages up to 43.5GHz, said the company. The ShockLine ME7869A series conducts long distance, full vector S-parameter measurements over distances up to 100 meters. —

Anritsu has released three models in the distributed modular two-port vector network analysers operating up to 8GHz, 20GHz and 43.5GHz, respectively provide unprecedented cost efficiency, flexibility, and ease of use to a variety of existing and emerging commercial and military antenna design applications.

The ME7869A is configured with two MS46131A 1-port VNAs that can each be directly connected to the antenna under test (AUT). Cable length for each VNA module can be equal or different lengths, depending on the application. It eliminates the need for long RF coaxial cables that create high loss, and phase and magnitude instability. The design addresses the need to accurately and repeatably measure antennas over long distances, such as in anechoic chambers and antenna test ranges.

Anritsu’s PhaseLync synchronisation technology enables two MS46131A VNAs to phase synchronise with each other over the full 100 meter distance. PhaseLync improves dynamic range and measurement stability of S-parameter measurements by eliminating the need for long cables necessary with conventional benchtop VNAs.

The distributed modular VNA solution in the MN25132A control module simplifies installation. It acts as a junction for the cables and supplies power to the two MS46131A VNAs. There is no need to attach separate power supplies to the two VNA heads. The control module also interfaces the two VNAs to a laptop configured with ShockLine software, explained Anritsu.

The ShockLine ME7869A brings can be used in an insertion loss application that requires long cable runs at frequencies up to 43.5GHz compared to alternative expensive benchtop VNAs that require superior dynamic range. For example, it can be used in satellite, materials measurement, aerospace and defence and signal integrity environments.
