Technologists at Sequans have published a new white paper entitled: Enabling Global Deployment of LTE IoT Devices With SAW-less Radio Design Architecture.

SAW stands for surface acoustic wave, and a SAW-less radio architecture is one without the SAW filters that are traditionally required in LTE system design.  New 3GPP Release 13 technologies, LTE-M and NB-IoT, designed for narrowband IoT applications, are based on half-duplex FDD (HD-FDD), a transmission mode whereby data is transmitted in a shared channel, one direction at at time, using two different frequencies.  HD-FDD eliminates the need for SAW filters, simplifying hardware design and lowering cost, and enabling a smart UE design utilizing programmable frequency tuning, which enables a single hardware design—a single SKU—to be deployed on any LTE frequency anywhere in the world.  The introduction of this Single-SKU technology completely removes the legacy cost barrier of having to modify UE design for each of the 30 plus LTE bands needed for worldwide operation.

Sequans’ new white paper describes how Sequans’ Single-SKU technology that is built into its Monarch LTE-M/NB-IoT Platform works.  Read all about it here.
