Smart modules poised to accelerate digital transformation and enable richer IoT devices

Smart modules unlock the full potential of IoT devices by adding greater intelligence and capability to modules so they can perform more than a single function. Common functions contained within a smart module include computing power, data storage and graphics processing along with connectivity, all of which were previously enabled via separate hardware. Now, with […]

Ask the Quexperts: What is satellite connectivity and how is it different to GNSS?

Although both the global navigation satellite system (GNSS) and satellite communication rely on satellites, they are distinct technologies that have separate capabilities. GNSS utilizes the relative position of satellites coupled with communication to a receiver mounted on an object or device to calculate the object’s location. Relying on GNSS systems such as GPS, GLONASS, Galileo, […]

RF Tx/Rx: how RF works and which factors affect its performance

x/Rx theory is highly complex and years of independent study are needed to achieve mastery of all the details of how electromagnetic variables can affect different application scenarios. RF Tx/Rx refers to the technical theory underpinning transmission and reception of RF (radio frequency) signals. The RF spectrum includes electromagnetic framework frequencies ranging from 30Hz to […]

Ask the Quexperts: What is GNSS RTK positioning?

Real-time kinematic (RTK) positioning is a technique designed to counteract signal errors in global navigation satellite system (GNSS) calculations and that enables far greater accuracy as a result. It utilizes a nearby reference station with known coordinates or a network of reference stations, also known as NRTK, to provide correction data in real-time via a […]

Avoid the unexpected by adopting Quectel feature for sudden module power loss

Changing habits in power generation and consumption are making power grids in some markets unstable, with brownouts, supply interruptions and even blackouts increasing in frequency. Much of the instability is caused by shifting user habits as workers remain at home, the adoption of renewable generation technologies which is seeing homeowners generating solar or wind energy […]

Antenna experts get ready for 6G future

With 5G still not deployed in many markets across the globe and coverage far from complete in countries that have deployed the technology, it may seem premature to be considering 6G. However, some technologies need to be prepared in advance of reaching deployment, and antennas for the 6G market are no exception.  Today, we’re at […]

Ask the Quexperts: How to choose the right module for telematics control units

The first consideration is to identify what use cases the telematics control unit will be utilized for. Telematics extends from relatively simple applications for identifying the location of a machine, vehicle or device, to enabling automation and ultimately autonomy for complex vehicles with numerous features. The connectivity requirements for each extreme differ widely with 4G […]

Ask the Quexperts: Do I really need 5G connectivity?

The package of capabilities that 5G connectivity offers brings together speed of more than 1Gbps, sub-1ms latency and unprecedented device density per cell. Combined, these make the technology seem like a complete no-brainer for designers and developers. As they specify cellular connectivity for the next generation of IoT and other devices, it’s understandable that the […]
