LTE CAT-M1 module eliminates gateways in IoT networks

Thu, May 27, 2021

Pre-tested and certified RYZ014A Cat-M1 cellular modules by Renesas are the company’s first cellular IoT modules to support the specification. Devices can directly connect to the internet using an existing communication infrastructure owned by mobile network operators, without the need for a gateway, says Renesas. This makes it economical to connect each device, which is beneficial when installing larger networks that require a low cost per unit.

To build a wireless IoT project from scratch, the RYZ014A module includes RF regulatory certification, PTCRB/GCF (network operators) certification and carrier certification for the customer’s network operator of choice.

The module has been certified with all major radio frequency regulations in the world as well as with leading network operators in North America, APAC and European countries.

The RYZ014A module is suitable for metering, smart home, infrastructure and industrial markets, where they can seamlessly interface Renesas microcontroller-based applications to the internet through their cellular network, for example Bluetooth Low Energy, Ultra-wide band (UWB) and Wi-SUN protocols.

Renesas has partnered with 4G and 5G chip and IoT module supplier, Sequans Communications, to provide the Monarch LTE CAT-M1 hardware and software technology used in the module.

Renesas offers customers a web-based portal, managed by ONE Tech, that provides easy access to read sensor values and manage SIM card plans remotely, reducing operating cost. ONE Tech’s embedded AI and cloud technology, with the Renesas CAT-M1 module offers embedded intelligence with an enterprise-grade platform, allowing customers to build, manage and scale smart machines in a cost-effective end-to-end ecosystem, says Renesas.

Support for world-wide frequency bands in a single design removes the need to create multiple customer platforms for different global regions, points out Renesas. There is also high output power supporting both power class options 20 and 23dBm and low current consumption in power saving mode of only 1.0 microA

The RYZ014A module and the RYZ014A-EVK evaluation kits are available now.

The RYZ014A modules can be combined with components from Renesas, such as power ICs, Li-ion battery charger, light-to-digital sensor, and RA family microcontrolelrs to create systems, such as remote industrial process monitoring and automatic plant watering with an LTE Connection.

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.
