Feature
Description
LTE Rx Diversity
Improved cellular link quality and reliability on all operating bands, by means of 2 receiving antenna inputs.
GNSS via modem
7
Full access to u-blox positioning chips and modules is available through a dedicated DDC (I
2
C) interface. This means
that from any host processor a single serial port can control the cellular module and the positioning chip or module.
For more details see the GNSS Implementation Application Note [5].
Embedded AssistNow
Software
7
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
®7
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
 Deep scan: the parameters of all surrounding cells of all mobile operators are sent
CellLocate
®
is available via a set of AT commands for CellLocate
®
service configuration and position request.
Hybrid Positioning
7
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
7
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.
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 board temperature, which can differ from ambient temperature.
Power saving
The power saving configuration is by default disabled, 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
7
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 TOBY-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.
7
Not supported by “02” product versions.
