NB-IoT is a low-power wide area network (LPWAN) technology designed for Internet of Things (IoT) devices and other applications that require low data rates and long battery life. It is a cellular network technology that uses narrowband radio spectrum to provide secure and reliable communications for IoT devices.
NB-IoT operates in licensed spectrum and uses advanced modulation and multiple access techniques to efficiently utilize available spectrum and support a large number of connected devices. It also uses advanced power management techniques to extend the battery life of IoT devices, which is critical for applications such as remote sensors and other devices where batteries cannot be easily maintained or replaced.
NB-IoT explained: What it is and future applications
Overall, NB-IoT is a key technology to enable the Internet of Things and support the growing number of connected devices that are being deployed across a wide range of industries.
In addition to low power consumption and long-range capabilities, NB-IoT offers increased security and reliability compared to other IoT technologies. It uses dedicated network infrastructure and strong signaling mechanisms to provide reliable communications, even in challenging environments such as dense urban areas or deep underground.
Overall, NB-IoT is a key technology to enable the Internet of Things and support the growing number of connected devices that are being deployed across a wide range of industries, from agriculture and manufacturing to smart cities and healthcare.
Is NB-IoT secure?
Since the underlying technology is less complex than traditional cellular modules, OEMs can more easily design, produce and deploy their products.
The same proven security and privacy protections of LTE mobile networks are also available, including support;
User identity is kept confidential.
Entity authentication,
Data integrity,
and mobile device identification.
NB-IoT use case requirements
NB-IoT meets the needs of many IoT use cases because it:
Efficiency: NB-IoT uses half-duplex communication, meaning that neither the module nor the cellular base station can transmit data at the same time. The use of this half-duplex communication, along with slower NB-IoT data rates, the use of a single antenna, and lower radio frequency (RF) bandwidth, minimizes the complexity of NB-IoT devices, thereby reducing costs. These simplifications reduce the cost of NB-IoT modules by 50% compared to standard LTE Cat-1 cellular modules.
Power consumption: Thanks to features such as Power Saving Mode (PSM) and eDRX (extended discontinuous reception), and NB Capacity IoT optimizes the energy used for small data transmissions, battery-powered edge modules can transmit data at 75% lower power than traditional LTE Cat-1 modules. As a result, IoT application manufacturers can create gadgets with a battery life of ten years or more.
Greater capacity: Up to 1 million NB-IoT devices can be connected per square kilometer, thanks to narrowband transmission, signaling optimization, adaptive modulation and hybrid automatic repeat request (HARQ) technology.
Better Coverage: NB-IoT utilizes massive signal repetition. Large signal repetition enhances NB-IoT coverage 5-10 times compared to competing cellular technologies. However, it reduces data throughput and increases power consumption. Because of this improved coverage, NB-IoT devices can now connect to cellular networks even when they are underground, inside buildings, or in rural areas.
How much does NB-IoT cost?
The cost of NB-IoT can vary depending on a number of factors, including the specific implementation, the type of equipment and infrastructure used, and the scale of the deployment. Therefore, it is difficult to provide a precise cost estimate for NB-IoT.
The cost of implementing NB-IoT may include the cost of purchasing and installing the necessary equipment and infrastructure, such as base stations, antennas, and other hardware. It may also include the cost of operating and maintaining the network, and the cost of purchasing or leasing the necessary spectrum.
In addition, the cost of NB-IoT may also depend on the type of deployment, such as a standalone NB-IoT network or a network integrated with an existing cellular network. Costs may also vary depending on the size of the deployment, with larger deployments typically requiring more equipment and infrastructure.
Overall, the cost of implementing NB-IoT will depend on a range of factors and may vary depending on the specific implementation and requirements.
Is NB-IoT bidirectional?
Yes, NB-IoT is a two-way communication technology, which means it supports both uplink and downlink communication.
In bidirectional communication, data can be transferred from the device to the network (uplink) or from the network to the device (downlink), making bidirectional communication possible. This is in contrast to unidirectional communication, where data can only be transferred in one direction (from device to network or from network to device).
Conclusion: The Importance of Having the Best IoT Connectivity
NB-IoT uses advanced multiple access techniques, such as time division multiple access (TDMA) and frequency division multiple access (FDMA), to achieve efficient use of available spectrum and support two-way communication. This allows IoT devices to send and receive data to and from the network, enabling a wide range of applications such as remote sensor monitoring, asset tracking, and other IoT use cases.
Overall, the two-way communication capability of NB-IoT is an important component of its design, enabling a wide range of IoT applications.
