How M2M Can Be Used

M2M has many benefits in business. Logistics managers can manage their fleets, helping them become cheaper, leaner and greener. M2M allows doctors to monitor patients remotely, so they can recover in their own home, freeing up hospital beds. Furthermore, it gives retailers, sales and marketing information they could previously only dream of, enabling them to monitor their assets 24/7 365 days a year.

Likewise in the home, M2M technology means that your fridge can order food from the supermarket when it’s empty. It means that your car can let your garage know when it needs a service, and your property can tell you if you’ve left the windows open or the heating on.

A Word on Best Practice...

The Importance of Tracking Data Usage

However, in all of these applications you need to be aware of how much data is being sent and received by your devices. Just like when you leave your roaming data on accidentally, making a mistake with your M2M data plan can lead to big bills – and in the home or for small-scale business use your best bet is to choose Luner, and the best pay as you go M2M SIM deal on the market today.

To illustrate precisely why choosing that best pay as you go M2M SIM can be of vital importance, we’re going to delve into the tech behind ALL M2M SIMs – including the best pay as you go M2M SIM cards money can buy, those from Luner – and walk you through how we get a wireless device to connect to the wireless radio network, and allow us to pass data traffic over that network.

M2M Communication, Step By Step:

Step One:

So to begin with we have a wireless device with a SIM card in it. This could be the best pay as you go M2M SIM from Luner or any other M2M SIM – the connection process remains the same. That SIM card will have a number of credentials on it to identify it with a core network, and the first thing it will do when it registers on a given wireless network is attach to the radio signal of a carrier. The SIM then makes contact with a network element called a ‘Home Location Register’, or ‘HLR’.

M2M Communication, Step By Step:

Step Two:

This HLR holds the details of that SIM card, and the services that it is allowed access to in the network. In a process known as ‘GSM registration’, credentials are handed from the SIM to the HLR, which then replies with the services that are available to the SIM. We now have 2 network points exchanging information – the SIM and the HLR.

M2M Communication, Step By Step:

Step Three:

Now that the SIM is registered on the network, it knows it has radio access and can start sending signals to other elements of the network in order to access them too. The next step for the best pay as you go M2M SIM from Luner (or any other M2M SIM) is to actually get access to the data part of the network. The SIM needs to perform what’s called a ‘data attach’, so it requests one from the HLR. If a SIM is allowed to use data, it will get back an affirmative result.

M2M Communication, Step By Step:

Step Four:

However… a SIM still can’t pass any data at this point. It hasn’t actually got a data connection – it just knows that it’s allowed to have a data connection. If you’re keeping score, we now have two devices talking to each other over two channels (the SIM and the HLR, talking over the data attach channel and the GSM registration channel), and all we know Is that we can be connected to this network and share data on it.
