What is MQTT

and Why Do You Need It in Your IoT Architecture?

Our world has become smaller and smaller with the advancements in technology. From the invention of the telephone to computers and the internet, it doesn’t take much effort to connect with someone ‘worlds’ away. Not only can we now talk to people on the other side of the planet in real-time, but thanks to IoT MQTT architecture, we can also talk to our devices. And even more exciting, our devices can talk to us!  

What is MQTT and Why Do You Need It in Your IoT Architecture?

So, why is it so interesting to be able to interact with our devices? Well, we are now living in a world with virtual home assistants, digitized appliances, and “smart” everything. These devices make it much simpler to do everyday tasks. Not too far in the past, it was common to hear Dad yell at Junior to get up and change the tv channel for him. With IoT devices, Dad can now yell into the remote control instead.  

These conveniences are only possible thanks to advancements in technology. We have given devices the capability to complete menial tasks.  This IoT MQTT architecture is doing the heavy lifting, while users can sit back and reap the benefits.  

What is MQTT?

MQTT, or MQ Telemetry Transport, is a messaging protocol. It provides clients with resource-constrained networks the ability to wirelessly transmit data. This works for people who have low bandwidth. MQTT is used for M2M or machine to machine communication.  

In other words, MQTT can gather a lot of information from a lot of different sources without overloading servers. 

What is IoT?

The internet of things, better known as IoT, is the term for physical objects that have software embedded in them. This allows these machines to “talk” to other software-enabled devices. MQTT is the leading protocol for connecting IoT devices and is in fact the preferred protocol. 

What Does IOT MQTT Architecture Do?

MQTT is a lightweight messaging protocol that can be used for connecting devices with minimal code and bandwidth. It has become the standard protocol for IoT messaging. Today’s IoT applications include automotive, manufacturing, telecommunications among many others which use MQTT in their designs.  

6 Distinct Ways IoT MQTT Architecture Makes a Difference

Size Matters– MQTT uses such a small number of resources that it can be used on microcontrollers. This lends itself to small clients and takes up minimal network bandwidth.  

Scalability– One of the best features of MQTT is the scalability. MQTT can connect millions of IoT devices.  

Security– MQTT easily encrypts messages. This helps messages stay safe from would-be cyber-attackers.  

Reliability– MQTT has three service levels that are very specific. They ensure message delivery. These service levels are 0, 1, and 2. Meaning at most once, at least once, and exactly once, respectively.  

Two-way Communication– It’s important for M2M communication to be two ways. In order for message broadcasting to groups of things, MQTT allows cloud-to-device and device-to-cloud messaging.  

Network Support– There are many cellular networks out there. Not all of them are very reliable. This is concerning for IoT devices that need those networks in order to properly function. MQTT supports all networks, even unreliable networks. The support MQTT offers reduces reconnection time between the broker and the client.  

MQTT with In-App Chat

In-App Chat uses IoT MQTT architecture in our chat APIs and SDKs to make your life easier. It doesn’t matter if your server is large or small, we have your back. In-App Chat helps ease the burden on your systems. This helps lower latency for your devices.
