NB-IoT (Cat. NB) and LTE-M (Cat.M)
NB-IoT and LTE Cat. M1 are new wireless technologies included in the 5G evolution
of cellular technology standards defined by the 3rd Generation Partnership Project
(3GPP).
NB-IoT and LTE Cat. M1 feature low power consumption and utilize LTE networks
based on licensed spectrum bands. These technologies are optimized for connectiv-
ity to machines, assets and sensors in order to enable IoT applications such as smart
cities, smart agriculture and remote asset management.
WISE-4671 series is a cellular based IoT wireless sensor node compliant with LTE
Cat. NB1 and Cat. M1 with external for flexible installation. In addition to offering var-
ious I/O types, WISE-4671 series provides a data logger and direct cloud connectivity
so that data can be published to the cloud by messaging protocol such as MQTT,
CoAP, LwM2M with secure socket supported.
WISE-4671 follows MQTT's publish and subscribe messaging model which is ideal
for low bandwidth, high latency, and data limits. Additionally, as an IoT device, WISE-
4671 also supports lightweight protocols such as CoAP, which are suitable for small
devices that are unable to communicate efficiently with limited resources. As MQTT
and CoAP are popular standards in the market, the data format can raise concern
over messaging protocols. Accordingly, WISE-4671 also supports the LwM2M proto-
col which has the management interface built on top of CoAP to enable device man-
agement operations.
There is also the official publication of OMA LwM2M2 Objects and Resources to alle-
viate data inter-compatiblity concerns. LwM2M is a protocol offering flexible and scal-
able device management with improved time to the market; especially for low power
devices with constrained processing and storage capabilities.

WISE-4671 Feature Highlights
Advantech's WISE-4671 NB-IoT/LTE-M wireless I/O module can be configured to
support either NB-IoT or LTE-M using the WISE Studio utility via a USB port.
For advanced industrial applications, WISE-4671 can be equipped with optional
GPS, a solar rechargeable battery, and an IP65-rated enclosure to protect from water
and dust ingress.
The WISE-4671 wireless I/O module features an intelligent modular design that sup-
ports various I/O configurations according to usage requirements. This allows users
to easily integrate their desired I/O module (WISE-S614, WISE-S614T etc.) with the
WISE-4671 module.
