Feature
Description
module and the u-blox M8 positioning chip or module. For more details, see the GNSS
Implementation Application Note [4].
Embedded AssistNow
Software
12
Embedded AssistNow Online and AssistNow Offline clients are available to provide better GNSS
performance and faster Time-to-First-Fix. An AT command can enable / disable the clients.
CellLocate
®12
Enables the estimation of device position based on the parameters of the mobile network cells
visible to the specific device based on the CellLocate
®
database:
 Normal scan: only the parameters of the visible home network cells are sent
CellLocate® is available via a set of AT commands for CellLocate® service configuration and
position request.
Hybrid Positioning
12
The current module position is provided by a u-blox positioning chip or module or the estimated
position from CellLocate
®
depending on which method provides the best and fastest solution
according to the user configuration.
Hybrid positioning is available via a set of AT commands that allow the configuration and the
position request.
Wi-Fi via modem
13
Full access to Wi-Fi modules is available through a dedicated SDIO interface. This means that
from any host processor a single serial port can control the cellular module and the short range
communication module.
DTMF decoder
14
During a voice call, the Dual-Tone Multi-Frequency detector analyses the RX speech (coming from
remote party). The detected DTMF symbols can be output via the related URC.
The feature can be enabled and configured through the +UDTMFD AT command.
In-Band Modem
13
In-Band modem solution for eCall and ERA-GLONASS emergency call applications over cellular
networks implemented according to the 3GPP TS 26.267 specification [10].
When activated, the in-vehicle eCall / ERA-GLONASS system (IVS) creates an emergency call
carrying both voice and data (including vehicle position data) directly to the nearest Public Safety
Answering Point (PSAP) to determine whether rescue services should be dispatched to the known
position.
Smart Temperature
Supervisor
Constant monitoring of the module board temperature:
 Warning notification when the temperature approaches an upper or lower predefined
threshold
 Shutdown notified and forced when the temperature value is outside the specified range
(shutdown suspended in case of an emergency call in progress)
The Smart Temperature Supervisor feature can be enabled and configured through the +USTS AT
command.
☞ The sensor measures the board temperature, which can differ from ambient temperature.
Power saving
The power saving configuration is disabled by default, but it can be enabled and configured using
the +UPSV AT command. When the power saving is enabled, the module automatically enters the
low power idle-mode whenever possible, reducing current consumption.
During idle-mode, the module processor core runs with the RTC 32 kHz reference clock, which is
generated by the internal 32 kHz oscillator.
Fast Dormancy
The Fast Dormancy feature, defined in 3GPP Rel.8, allows reduction of current consumption and
network utilization during periods of data inactivity. It can be activated and configured by +UFDAC
and +UDCONF=61 AT commands.
LTE cDRX
Both the Long DRX Cycle and the Short DRX cycle are supported for LTE Connected Discontinuous
Reception, allowing reduction of current consumption and LTE network utilization during periods
of data inactivity.
Power Saving Mode (PSM)
as specified in 3GPP
Release 12
13
The Power Saving Mode (PSM) feature, defined in 3GPP Rel.12, allows further reduction of the
module current consumption by decreasing the signaling load between the module and the
network on non-access stratum level during periods of data inactivity. It can be activated and
configured by dedicated AT commands.
Table 3: Some of the main features supported by LARA-R2 series modules
☞ u-blox is extremely mindful of user privacy. When a position is sent to the CellLocate
®
server, u-blox
is unable to track the SIM used or the specific device.
13
Not supported by “02” and “62” product versions.
14
Not supported by LARA-R204 module “02” product version, LARA-R220 modules “62” product version.
