M2M One SIM Cards now work on Telstra’s Cat M1 IoT Network
As of September 2017 all SIM Cards provided by M2M One now have access to the full Telstra IoT Network in addition to 3G & 4G coverage.
The Cat M1 service operates on Telstra’s 4GX network which utilizes band 28 (700Mhz) and can only be accessed by Cat M1 compatible 4G devices.
M2M One SIM Cards are powered by the Telstra mobile network and as such are subject to Telstra’s coverage, service and network uptime – See below:
Device coverage depends on where you are, the device you are using and whether it has an external antenna attached.
You should be aware that the Telstra coverage maps displayed have been created using tools that predict the likely areas of outdoor coverage. We have not individually tested every particular location within the identified coverage areas for coverage, nor any indoor locations or sub-surface areas. This means that while the footprint of coverage outlined on the maps is generally accurate, there will be specific areas described as being within a coverage area where your device will not work. This is a common characteristic of wireless systems. For example, actual coverage could be degraded or not existent in specific locations due to certain physical structures or geographic features or as a result of the device used. Physical structures which may block or inhibit coverage could include basements, lifts, underground car parks, concrete buildings, tunnels and road cuttings. The specific nature of building materials used in an office or dwelling also impacts on the coverage within, with some materials such as steel framing and metallic window films having a significant impact on coverage within a building. Geographic features which may block or inhibit coverage could include formations such as hills and mountains or even trees.
The offshore coverage shown is only indicative of where a device may operate. Factors beyond Telstra’s control such as the weather, tides, sea conditions and your antenna installation (type and height of antenna above sea level) can significantly influence the actual user experience of coverage, data speed and performance. Public mobile networks must not be relied upon as a primary method of emergency communication at sea.
Data speeds experienced on Telstra’s mobile networks may be affected by network availability, the type and configuration of customer equipment, or device used, the performance of external networks (for example the Internet), the signal strength available to the device, and other factors such as the type of application.
What is LTE Cat M1?
LTE Cat M1 is a low‑power wide‑area (LPWA) technology that supports M2M & IoT devices with low to medium data requirements with average upload and download speeds of 375 kb/s.
Unlike the other LPWA 4G standard NB‑IoT, LTE Cat M1 can be used for mobile IoT/M2M devices, as it handles hand‑over between cell towers in a similar fashion to LTE . For example, if a device crossed between several different network towers, a Cat M1 can maintain the connection similar to a normal 4G or 3G device. However an NB‑IoT device needs to re‑establish a new connection for each new location.
Unlike NB-IoT, Cat M1 also supports voice functionality via VoLTE (voice over LTE), which means it can be used for applications like man-down alarms, elderly care, independent living and other applications requiring human interaction.
Features of LTE Cat M1
- Low Power Consumption
- Extended Coverage and Better Building Penetration
- Voice Over LTE Support
- Full Mobility & Handover
- Reduced Hardware Costs
- Massively Scalable
Where can I purchase Cat M1 IoT/M2M Products?
As Cat M1 technology is still a fairly new technology there are limited options for total finished product and instead you may need to build your product from a board level using a Cat M1 Module.
Below is an example list of companies with products that support Cat M1:
- M2M Connectivity – Australia’s largest supplier of M2M & IoT Modems, Sierra Wireless Modules, Devices and Accessories.
- Digital Matter – Provide 4G & Cat-M1 vehicle and asset tracking solutions
- ETM Pacific – Provide a 4GX compatible serial modem & Modules from Gemalto
- GLYN – Provide Cat M1 Modules from Telit
- uBlox – Provide Cat M1 Modules in the SARA R4 Line
