LTE-M vs Cat-1 (Category 1) are cellular communication technologies, but they are designed for different use cases and have some key differences.
LTE-M vs Cat-1
Data Rates
LTE-M: LTE-M offers relatively low data rates, typically 375 Kbps for downlink and 300 Kbps for uplink. This is sufficient for many IoT applications that transmit small amounts of data at infrequent intervals.
Cat-1: Cat-1 provides higher data rates, with speeds ranging from 10 to 100 Mbps for downlink and 5 to 10 Mbps for uplink. This is more suitable for applications that require real-time or higher-bandwidth data communication.
Power Consumption
LTE-M: LTE-M is optimized for low power consumption, making it suitable for battery-powered IoT devices that must operate for extended periods without frequent recharging or battery replacement.
Cat-1: Cat-1 consumes more power than LTE-M, which may not be as suitable for battery-constrained devices that require long-term operation on a single charge.
Coverage and Availability
LTE-M: LTE-M typically offers better coverage in areas with weak signal strength or in-building coverage. It is designed to penetrate obstacles and provide reliable connectivity in challenging environments. However, CAT-M or NB-IoT are simply not yet ready in most markets.
Cat-1: Cat-1 may offer faster data rates but might have slightly less coverage in certain situations than LTE-M. Cat-1 is available today and widely supported by carriers worldwide. Thus, Cat-1 network availability is actually better in most markets.
Cost
LTE-M: LTE-M modules and services are often designed to be costeffective, making them attractive for low-cost IoT deployments.
Cat-1: Cat-1 modules and services are more widely used and relatively less expensive than LTE-M.
Use Cases
LTE-M: LTE-M is primarily designed for low-power, low-data-rate IoT (Internet of Things) and M2M (Machine-to-Machine) applications. It is optimized for devices that transmit small amounts of data intermittently and have long battery life.
Cat-1: Cat-1, on the other hand, is designed for applications that require higher data rates and are not as concerned about power consumption. It offers faster data transmission speeds compared to LTE-M and is suitable for applications like video streaming and certain types of IoT devices that require more bandwidth.
Summary
The choice between LTE-M and Cat-1 depends on the specific requirements of your IoT or M2M application. If your priority is low power consumption, small data payloads, and cost-effectiveness (like a tracking project), LTE-M may be a better choice. However, if you need higher data rates and can accommodate higher power consumption, Cat-1 might be more
suitable for your application.
The other factor that should be considered when deploying a national or worldwide tracking project is network availability. LTE-M and NB-IoT networks are still under development in most countries, but Cat-1 has more coverage. This means your devices can always be on-line. Check our whitepaper here.
