Ultimate SIM Card for Narrowband IoT - Hologram SIM
Internet of things Ultimate SIM Card for Narrowband IoT - Hologram SIM

The reason of today’s blogpost is to lighten up the advantage of Hologram SIM. This card has global connectivity for your IoT or IIoT systems in over 196 countries and 550 carriers all around the world. For sure, it helps you to unify the SIM card selection process if your applications are located in supported areas.

Internet of things Programming Narrowband IoT Applications

After looking into some of the details of NBIoT modules an LTE Cat NB as a technology itself, it’s now about time to get started with programming Narrowband Modules such as the BC68/BC95 from Quectel or uBlox’ SARA N410. Looking at the spec sheets of these modules can be a bit overwhelming, so what’s really necessary to connect an IoT device to a backend service? In this series we’re showing how to get started!

Internet of things ThingForward NB-IoT Shield - Real Life Example Demonstration

As long as we are dealing with NB-IoT, we considered of being more specific about real life examples using our Grove connector and narrowband protocol. Today we will be programming by using an MCU from Adafruit, NB-IoT module, OLED screen and some sensors in order to show the capabilities of our new hardware on a real life NB-IoT task. Please remind that, using these modules and sensors will give you a fresh start, then you can easily customise this setup with desired sensors, actuators or protocols.

A first look at the Arduino MKR1500 for LTE Narrowband & LTE-M connectivity
Internet of things A first look at the Arduino MKR1500 for LTE Narrowband & LTE-M connectivity

For the past four months, we’ve been taking a deeper look into Narrowband as a mobile/M2M technology, some of the modules currently available and its applications in general. From the perspective of boards and modules, we’re really excited about Arduino’s offering of their new MKR 1500, a small but powerful board combining a 32bit Cortex M0+ MCU and an radio module for LTE Narrowband and LTE-Cat M.
