How can IoT devices use SATCOM for reliable data transmission?

由人工智能和领英社区提供技术支持

Internet of Things (IoT) devices are becoming more prevalent in various applications, such as agriculture, smart cities, environmental monitoring, and logistics. However, many of these devices operate in remote or harsh environments, where terrestrial networks are unreliable, unavailable, or costly. This is where satellite communications (SATCOM) can offer a viable solution for reliable data transmission.

1 What is SATCOM?

SATCOM is the use of artificial satellites to provide communication services, such as voice, data, video, and navigation. SATCOM can cover large areas, reach inaccessible locations, and offer global connectivity. SATCOM can also complement terrestrial networks, such as cellular, Wi-Fi, or fiber-optic, by providing backup, redundancy, or extension.

Nice to see interest. However the satellites are definitely not artificial, and they have been providing not just IoT services over the many years , but are extremely important for safety, or emergencies, such as the earthquake in Turkey. Satcom is ingrained within all government, worldwide and provides communication, data ( for things like news agencies in remote areas ), email, text, safety at sea for fisherman that is invaluable, remote control and much much more

SATCOM is Satellite Communications. A satellite, in astronomical terms, is a celestial body that orbits around a planet. The closest natural (not artificial) satellite of Earth is the Moon. In aerospace terms, a satellite is a space vehicle that orbits around Earth or another planet. Satellite communication is the use of artificial satellites to provide communication links between points on Earth. Satellite communication play a vital role in the global telecommunications system as it can reach parts of our planet that terrestrial telecommunication infrastructure is unable to reach.

2 How can IoT devices use SATCOM?

IoT devices can use SATCOM to send and receive data from a satellite, either directly or through a gateway. Direct communication means that the IoT device has a built-in satellite modem or terminal, which can communicate with the satellite without any intermediate device. Gateway communication means that the IoT device connects to a local gateway, such as a router or a base station, which then communicates with the satellite.

To make it a bit simpler, IoT for SatCom is the future for remote controlling areas out of reach, or having places that need to be run but cannot have human assistance in house such as in islands monitoring weather, earthquakes and more. As you know over just the past years everyone is working from home remotely, right? Think about this as the same thing. People will be able to have remote servicing jobs using IoT satcom devices to maintain unattainable areas, or places that need 24/7 handling. The satcom is providing much much more , but this is a simple way to think of it.

A recent disruptive breakthrough is that IoT devices designed for terrestrial infrastructure can use SATCOM without any modifications due to the direct to user satellites using terrestrial frequency range to complement the terrestrial infrastructure. This means that IoT devices do not need a build in satellite modem and do not need to use a gateway to communicate with a satellite.

3 What are the benefits of SATCOM for IoT?

SATCOM for IoT can provide numerous advantages, such as improved coverage in areas where terrestrial networks are weak or nonexistent, like rural, maritime, or polar regions. This can enable applications that require wide-area monitoring, tracking, or control. Additionally, SATCOM can provide consistent and reliable data transmission, even in challenging weather conditions or disasters. Furthermore, it can reduce infrastructure and maintenance costs of terrestrial networks, particularly in remote or harsh environments, thus lowering the total cost of ownership and operation of IoT applications.

If you need a global IoT network you may need agreements with multiple local service providers in different countries/regions. Using a satcom provider with global coverage you just need one global service agreement for all your IoT devices.

I’d have to say this statement covered many areas well with easier ways of understanding and imagination of what it is doing and what it can do in future times.

4 What are the challenges of SATCOM for IoT?

SATCOM for IoT also faces some challenges, such as limited bandwidth, high power consumption, and regulatory and technical issues. The limited spectrum and capacity of SATCOM can limit the data rate and volume of IoT devices, which can be a problem for applications that require high-throughput, low-latency, or real-time data transmission. Additionally, SATCOM requires more power than terrestrial networks, draining the battery life of IoT devices and disrupting applications that require low-power, long-lasting or energy-harvesting devices. Finally, the complex regulations and standards of SATCOM, which vary by country, region or frequency band, can affect the interoperability, compatibility and compliance of IoT devices and SATCOM systems.

5 How can multiple access techniques improve SATCOM for IoT?

Multiple access techniques are methods that enable multiple users or devices to share the same communication channel or resource, such as frequency, time, or code. These techniques can improve SATCOM for IoT in several ways, including increasing efficiency, reducing interference, and enabling diversity. Examples of multiple access techniques for IoT and SATCOM include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Orthogonal Frequency Division Multiple Access (OFDMA), and Non-Orthogonal Multiple Access (NOMA). FDMA is simple and robust, but can waste spectrum and cause cross-talk. TDMA is efficient and flexible, but can introduce delay and synchronization issues. CDMA is resilient and secure, but can cause interference and complexity. OFDMA is adaptive and robust, but can require high processing power and synchronization. Finally, NOMA is spectral and energy efficient, but can require advanced signal processing and channel estimation.
