Applications of Cat 1:

Cat-1 is suitable for applications that require moderate data rates, good coverage, and cost sensitivity, such as smart meters, sepeda bersama, Otomatisasi Industri, dan banyak lagi.

Understanding of Cat M

LTE Cat M (also known as LTE-M or eMTC) adalah kekuatan rendah, wide-area (LPWA) cellular IoT technology standardized under 3GPP Release 13. Designed to bridge the gap between high-speed LTE and ultra-narrowband solutions like NB-IoT, Cat M delivers balanced performance for IoT applications requiring mobility, moderate data rates, and extended battery life—all while operating on existing 4G LTE networks. It has relatively low bandwidth, but is sufficient for most IoT applications with low data transmission requirements.

Max speeds of 1 Mbps (vs.. Cat 1’s 10 Mbps) limit its use for bandwidth-heavy applications like video streaming or large file transfers.

Limited Connection Density:

Supports ~10,000 devices per cell, far fewer than NB-IoT’s 50,000+ devices per cell.

Network Deployment Variability:

Requires carrier support for LTE-M, which is less globally standardized than NB-IoT in some regions (misalnya, Europe prioritizes NB-IoT).

Applications of Cat M:

Cat-M is suitable for applications requiring low power consumption, wide coverage, and low data transmission demands, such as smart metering, pelacakan aset, pemantauan lingkungan, and similar use cases.

Understanding of NB-IoT

NB-IoT is a low-power, wide-area (LPWA) cellular technology standardized under 3GPP Release 13, designed specifically for IoT applications requiring ultra-low power consumption, massive connectivity, and deep coverage. Unlike traditional LTE standards, NB-IoT operates in narrow bandwidths (180 KHZ) to deliver cost-effective, energy-efficient connectivity for static, low-data devices—even in challenging environments. It offers very limited bandwidth, yet remains fully capable of transmitting small amounts of data.

Key Features of NB-IoT:

Biaya:

NB-IoT modules have the lowest cost, making them well-suited for large-scale deployments and cost-sensitive applications. Namun, due to their low data rate and bandwidth, they are not suitable for applications requiring high data throughput.

Disadvantages of NB-IoT:

No Mobility Support:

Designed for static devices and lacks seamless handover between cell towers. Unsuitable for mobile applications like asset tracking, perangkat yang dapat dikenakan, or vehicle telematics.
