So let's start with the question, what is LTE-M?
Long Term Evolution for Machines: LTE-M. LTE-M is the simplified industry term for the LTE-MTC low power wide area (LPWA) technology. It specifically refers to LTE CatM1, suitable for IoT.
LTE M is an extension of 4G that operates using the mobile network. This network is an example of what is commonly known as LPWAN technology – or in other words, low-power, wide-area communication solutions.
what are the Advantages of LTE M?
1. Energy consumption????, and to be exact, the reduction of it.
This is done in two ways;
- Power Saving Mode, allows the object to go into a scheduled hibernation whilst still keeping the network updated with its status (no network disconnection). Power Saving Mode is particularly useful in objects which do not need to be contactable in between sending information.
This results in the extended objects’ battery life to anywhere between 5 and 10 years. This is useful with difficult-to-access locations and great numbers of stand-alone endpoints where no fixed power supply is possible.
- E-DRX (Extended Discontinuous Reception). This is a mechanism that helps to extend the sleep time in the device’s cycle. Or in other words, the time during which a modem will not receive information – to save power.
2. Indoor overage
The protocol specifically used for LTE-M is called MAT M-1. This gives better penetration of radio waves, leading to improved indoor coverage. LTE-M offers significantly better coverage in locations where it’s tough getting objects to connect using 2G/3G/4G networks.
3. Latency and speed
As it uses the 4G network, its performance in terms of speed and latency is extremely good and it has access to all services (Data/Voice/SMS). This is a great advantage for objects used as part of emergency equipment (lifts, remote assistance devices).
4. Long term continuity
Eventually, LTE-M will be an integral part of 5G and expected to stay for the long term. This means you won’t need to change your device any time soon if you opt for an LTE-M module (which is particularly worth bearing in mind given the upcoming demise of 2G).
5. Lower cost of hardware
The modules are less expensive than the equivalents for other GSM technology.
Last but not least; what about roaming and having one SIM, one contract, for multiple countries? TNF has over 50 countries live with LTE-M now, here is roaming supported. Roaming agreements developing fast so our profiles getting more and more complete. More will follow as expansion is an ongoing development. This is a great priority for us and cooperative parties.
