Sequans 5G/4G IoT Tech Dictionary

Active Mode

When the user device is awake and actively receiving or transmitting.


Extended discontinuous reception. eDRX is a technology that allows sleep mode (discontinued reception) for a prescribed period of time in order to save battery life. eDRX allows the user device to tell the network how long it would like to sleep before checking back in.


Sequans’ proprietary algorithm delivering extremely low eDRX power consumption.


Enhanced mobile broadband refers to the initial phase of 5G non-standalone deployments which provides greater bandwidth along with moderate latency improvements on both 5G NR and 4G LTE. This will help to develop mobile broadband use cases, such as emerging AR and VR, ultra HD, or 360-degree streaming video.


Embedded universal integrated circuit card; also known as embedded SIM (subscriber identity module). eUICC or eSIM is a removable or non-removable UICC which enables the remote and/or local management of profiles in a secure say. A discrete eUICC is an eUICC implemented on discrete hardware (card or chip).


Integrated universal integrated circuit card; also known as integrated SIM. iUICC or iSIM is an eUICC implemented on a tamper resistant element (TRE) that is integrated into a systemonchip (SoC), optionally making use of remote volatile/non-volatile memory.

Idle Mode

When the user device is not actively transmitting, but in light sleep and ready to transmit on short notice.


Monarch’s embedded location engine that provides highly accurate indoor and outdoor positioning without additional radios.


The ability of Monarch to dynamically select its operation mode, either LTE-M or NB-IoT.


Also known as LTE Category M1 or LTE Cat M. One of two technology standards developed by 3GPP and defined originally in the Release 13 standard to address narrowband and lower data rate IoT (Internet of Things) applications. LTE-M defines LTE category M1, which is 1 Mbps downlink peak data rate in a 1.4 GHz channel size.


Massive machine type communications began in 3GPP Release 13/14 with low power wide area technologies, including NB-IoT, and is expected to meet most 5G mMTC requirements.


Sequans’ world-leading dual-mode LTE-M/NB-IoT chip platform.


Narrowband IoT; also known as LTE Category NB1 or LTE Cat NB1 or NB2. The second of the two technology standards defined originally in 3GPP Release 13 to address narrowband and lower data rate IoT applications. NB-IoT defines LTE category NB1, which is about 20 kbps downlink peak rate in a 200 kHz channel size. Release 14 adds definition for LTE category NB2, which is 120 kbps downlink.


Power saving mode. PSM is a sleep mode where the user device tells the network it is going to sleep for an indefinite period of time. When the user device wants to transmit, based on some logic, event trigger, or timer, it wakes up, transmits to the network and remains in receive mode for a little while.

Rock Bottom

The absolute lowest level of power consumed by a device in sleep mode (PSM or eDRX). Sequans’ Monarch delivers rock bottom power consumption of 1 microamp.

Secure Enclave

The dedicated secure area on a systemonchip that provides hardware security for iUICC/iSIM and includes a dedicated secure processor that can run secure apps such as payment. Monarch 2’s integrated secure enclave provides industryhighest EAL5+ security.


Monarch’s ability to support all RF frequencies from 617-2200 MHz for global operation and roaming with a single hardware configuration.


Ultra reliable low latency communications delivers full end-2-end latency reduction in 5G for mission critical applications that are especially latency-sensitive and require wide coverage.
