NB IoT/LTE-M product testing
Narrow Band Internet of Things (NB IoT) has become an important branch of Internet of Things. NB IoT is built on cellular networks and consumes only about 180kHz of bandwidth. It can be directly deployed on GSM networks, UMTS networks, or LTE networks to reduce deployment costs and achieve smooth upgrades. LTE-M， LTE Machine to Machine is an IoT technology based on the evolution of LTE. It is called Low Cost MTC in R12 and LTE enhanced MTC (eMTC) in R13, aiming to meet the needs of IoT devices based on existing LTE carriers.
Narrowband Internet of Things (NB IoT) and LTE-M (LTE Machine to Machine) are two low-power wide area network (LPWAN) technologies based on cellular networks, designed specifically for Internet of Things (IoT) applications. They are designed to meet the needs of IoT devices for low power consumption, wide coverage, low cost, and large-scale connectivity. The following is a detailed introduction and comparison of these two technologies:
Narrowband Internet of Things (NB IoT)
Technical features:
Narrowband design: occupying only 180kHz bandwidth, suitable for small data transmission.
Low power consumption: Supports PSM (Power Saving Mode) and eDRX (Extended Discontinuous Reception), significantly extending device battery life (up to 10 years).
Wide coverage: It has a wider coverage range and stronger penetration capability than traditional LTE, making it suitable for complex environments such as underground and remote areas.
Big Connection: Supports connection of tens of thousands of devices per community, suitable for large-scale IoT deployment.
Low cost: Simplified protocol stack and hardware design, reducing device costs.
Deployment method:
Can be deployed independently.
Guard bands can be deployed within the LTE or GSM frequency bands.
Can be deployed within the LTE frequency band (In Band).
Application Scenario:
Intelligent meter reading (water meter, electricity meter, gas meter).
Environmental monitoring (temperature and humidity, air quality).
Intelligent parking.
Agricultural monitoring.
Asset tracking.
LTE-M（LTE-Machine-to-Machine）
Technical features:
Bandwidth: Supports 1.4MHz bandwidth, with a data transmission rate higher than NB IoT.
Low power consumption: Supports PSM and eDRX, with a battery life of several years.
Mobility: Supports high-speed mobile scenarios (such as in car devices).
Voice support: Supports VoLTE (Voice over LTE), suitable for IoT applications that require voice functionality.
Low latency: Suitable for applications that require high real-time performance.
Deployment method:
Based on the existing LTE network deployment, no additional spectrum resources are required.
Application Scenario:
Wearable devices.
Intelligent logistics.
Smart home.
Health monitoring.
Connected cars.
Comparison between NB IoT and LTE-M
| feature | NB-IoT | LTE-M |
|---|---|---|
| bandwidth | 180kHz | 1.4MHz |
| data rate | Low (about 200kbps) | Higher (about 1Mbps) |
| power consumption | extremely low | low |
| coverage | Wide (20dB higher than LTE) | More extensive |
| IP Mobility Support | Limited (suitable for static or low-speed moving scenarios) | Support high-speed movement |
| Voice support | not supported | support（VoLTE） |
| delay | higher | lower |
| cost | lower | lower |
| Application scenarios | Static, small data volume, low-power scenarios | Strong mobility, moderate data volume scenario |
summary
NB IoT: Suitable for static or low-speed mobile scenarios with extremely high cost, power consumption, and coverage requirements, such as smart meter reading, environmental monitoring, etc.
