Lets learn about Cellular Modems vs Cellular Modules:
In the digital era we currently live in, it's all about connections. We want our smartphone to be able to connect to our doorbell, our refrigerator, and our wristband fitness tracker. We crave connections within our homes so that a single command from our smartphone or another device can lock the doors, turn the lights out, schedule the coffee maker to begin brewing at before we wake up, and set the home's alarm when we're away. This huge demand for interconnection in the IoT (Internet of Things) has led to a huge increase in the manufacture of such devices.
Each of these devices, be it an appliance, watch, phone, tablet, or street light, must have a way to connect to the internet and other IoT items. To do so, manufacturers use cellular technology. The most common types of such technology include cellular modems and cellular modules. Without these components, your smart devices would be unable to connect to the internet or to each other, rendering them quite a bit less smart.
Manufacturers of smart devices and other items in the IoT must decide which one of these components best fits their unique needs, including the cost to have them built and programmed. They each offer different levels of connectivity and functionality and can be adapted to meet the specific needs of the manufacturer. The amount of work that needs to be done to achieve those specific goals is a major factor used by the manufacturer to determine which type is best for them.
The more complete the cellular component, the more expensive it will be. However, the less complete types require more expertise and time to get ready for integration into the smart device. Paying people with the correct expertise does not come cheap, and it may swing the cost in favor of the more complete options.
Here is a bit of information about each of those items and their unique benefits and shortcomings.
Before we discuss cellular modems vs modules, we need a bit of information about the technology they are built on: chipsets.
