Anritsu upgrades Network Master Pro MT1000A for 5G and O-RAN services

Wed, May 26, 2021

Claimed to be the smallest tester in its class to support mobile networks up to 100Gbits per second, the Network Master Pro MT1000A has been upgraded by Anritsu with a synchronous measurement function.

The MU100090B is a GNSS disciplined oscillator supporting GPS, Galileo, GLONASS, Beidou and QZSS. It receives signals from each of GNSS to output a UTC-traceable reference time signal as well as 10MHz signals as a time-synchronous, high-accuracy reference timing supplied to the portable MT1000A, supporting SyncE Wander and PTP tests up to 25Gbits per second for measuring network time synchronisation.

Anritsu hopes to facilitate construction of time-synchronous infrastructure, a key technology supporting 5G networks which are expected to support increasing levels of services such as hi-definition video streaming, autonomous driving, IoT sensing and smart factories.

Multiple MT1000A testers at remote sites can be operated and monitored from the central office using the site over remote access (SORA) MX109020A software to help quickly pinpoint synchronisation problems.

The company has added the high performance GNSS disciplined oscillator MU100090B to the range of modules for the portable, battery-operated MT1000A to help simplify on-site time-synchronisation tests.

The deployment of 5G communications networks brings advantages such as high speeds, high reliability, low latency, and multiple simultaneous connections. The millimetre wave (mmWave) band used by 5G technology employs the TDD time-division duplexing technology to manage the timing of uplink and downlink signals. This technology requires that the time at all base stations is precisely synchronised. Additionally, an IoT-based society will require co-operation between devices exchanging position information acquired using observed time difference of arrival (OTDOA) positioning technology, which requires high-accuracy time synchronisation between base stations.

Base stations can be synchronised using wired-network technologies called SyncE and PTP, which require both measurement of the network time-synchronisation performance when installing and maintaining a cell site, and a guaranteed network performance, explains Anritsu.

The O-RAN Alliance increasingly requires tests of overall mobile network time-synchronisation performance to assure interconnectivity.

Time-synchronisation quality is indicated by drift from co-ordinated universal time (UTC), so precise time-synchronisation measurement requires expensive infrastructure, adds Anritsu.

LoRa transceiver modules run Bluetooth Low Energy 5.0 stack

Tue, May 25, 2021

IoT modules developed by Miromicro run a compatible Bluetooth Low Energy 5.0 stack to enable wireless connectivity to sensors, devices and systems communicating at high data rates or over a long distance. The FMLR-8x-x-STLx LoRa IoT modules are available from Avnet Silica.

The modules are built on Semtech’s 2.4GHz SX1280 LoRa transceiver and do not require any additional BLE 5.0 devices, advises Avnet Silica. Target IoT applications include track and trace, building automation, construction monitoring, mining, farming, telemetry and remote data logging.

The modules allow multiple wireless protocols to run on the same microcontroller, i.e., LoRa and BLE 5.0. The combination of technologies in the same wireless module enables commissioning, configuration, local data monitoring, or firmware update of IoT devices using smartphones, tablets, car navigation systems, or other iOS or Android-based devices. After the initialisation process, the module operates LoRa 2.4GHz long range applications anywhere in the world. Dual-protocol IoT devices usually require separate Bluetooth Low Energy chipsets to be separately integrated for connection to mobile phones, but after initial setup, these modules do not require additional Bluetooth Low Energy chipsets.

The FMLR-8x-x-STLx module-family is available with options, including extra onboard flash memory to enable over-the-air (OTA) updates and local data buffering in times when cloud connectivity is temporarily unavailable. Using Miro Edge 2.4GHz LoRa gateways, the modules support Semtech’s active-radar-based ranging and localisation technology for both indoor and outdoor environments. Further supported high-bit rate modulation schemes include the robust and bandwidth-efficient FLRC and (G)FSK. Bluetooth Low Energy allows bi-directional communication with smartphones, tablets and other devices, while optional low power, high precision, temperature-compensated oscillators (TCXO) for both RTC and radio are also available.

The module’s firmware, including the wireless stack, can be updated via SWD, UART Bootloader or optional firmware over-the-air (FOTA) to support fast prototyping and development.

Miromico’s FMLR-8x-x-STLx LoRa modules, development kits and dual-band LoRa gateways are available now from Avnet Silica.

Xsens tracks further with rugged modules

Fri, May 21, 2021

Two products have been added by Xsens to MTi 600-series. They extend the portfolio of industrial tracking modules with and without an integrated satellite positioning receiver.

The first module to be added is the MTi-670G. This is a GNSS/inertial navigation system (INS) module. The second is a rugged attitude and heading reference system (AHRS), the MTi-630R. Both additions are suitable for use in harsh environments in maritime, mining and agricultural applications, says Xsens.

The MTi-670G and MTi630R are housed in an IP68-rated aluminium enclosure which measures 40.9 x 56.5 x 36.8mm. This design is “highly vibration- and shock-proof”, says Xsens. Both modules also feature standard controlled area network (CAN) and RS232 interfaces and an output data rate of up to 400Hz.

The MTi-670G GNSS/INS module includes a u-blox ZED F9 GNSS receiver. Sensor fusion firmware combines the receiver’s inputs with integrated 3D attitude (tilt, inclination) and heading measurements to provide absolute positioning accuracy of better than ±1m. The sensor has support for Xbus and standard NMEA and CAN protocols, for ease of integration into designs. There is also the provision of Xsens’ MT Software suite for developers. This includes the MT Manager graphical user interface (GUI) for Windows or Linux operating systems and a magnetic field mapper function.

The MTi-630R AHRS is a ruggedised version of Xsens’ MTi-630 AHRS. It offers roll/pitch measurement accuracy of ±0.2 degrees, and heading accuracy of ±1 degree. It is also supported with the MT Software suite, which also includes drivers for the LabVIEW, ROS and GO development languages.

The MTi-670G and MTi-630R are available for sampling now. Ruggedised versions of the MTi-610 inertial measurement unit (IMU) and MTi-620 vertical reference unit (VRU), the MTi-610R and MTi-620R, are available on request.
