Feature

Description

Antenna detection

The ANT_DET pin provides antenna presence detection capability, evaluating the resistance

from the ANT pin to GND by means of an external antenna detection circuit implemented on the

application board. The antenna supervisor (i.e. antenna detection) feature can be enabled

through the +UANTR AT command.

BIP

Bearer Independent Protocol for over-the-air SIM provisioning.

Dual stack IPv4/Ipv6

Capability to move between Ipv4 and dual stack network infrastructures.

Ipv4 and Ipv6 addresses can be used.

Firmware update Over AT

commands (FOAT)

Firmware module update over AT command interface.

The feature can be enabled and configured through the +UFWUPD AT command.

u-blox Firmware update

Over The Air (uFOTA)

u-blox firmware module update over the LTE air interface client/server solution using LwM2M.

Power Saving Mode (PSM) The Power Saving Mode (PSM) feature, defined in 3GPP Rel.13, allows further reduction of the

module current consumption maximizing the amount of time a device can remain in PSM low

power deep-sleep mode during periods of data inactivity. It can be activated and configured by

the +CPSMS AT command.

eDRX

Extended mode DRX, based on 3GPP Rel.13, reduces the amount of signaling overhead

decreasing the frequency of scheduled measurements and/or transmissions performed by the

module in idle mode. This in turn leads to a reduction in the module power consumption while

maintaining a perpetual connection with the base station.

Coverage Enhancement

(mode A and mode B)

Coverage Enhancement modes introduced in 3GPP Rel.13 are used to improve the cell signal

penetration.

LTE-M and NB-IoT 3GPP

release 14 features

For LTE-M: Larger max UL TBS (2984 bits instead of 1000 bits), Enhanced PUCCH repetition in

CE mode B (64 and 128 repetition factor)

For NB-IoT: Cat-NB2 higher data rate (with 2536 bit TBS), Release assistance indication, Power

class 6 (maximum transmit power of 14 dBm) configurable by dedicated AT command, RRC

connection re-establishment for the control plane CIoT EPS optimization, 2 UL/DL HARQ

processes, Non-anchor paging and RACH, E-CID positioning
