Project14 | Sub-1GHz Band Challenge: Win a Pair of STM32 Nucleo-64 Dev Boards for Your Project Proposal!

tariq.ahmad

In the Comments Below:  Let Us Know Your Project Ideas for the Sub-1 GHz Band Challenge!

You are free to use whatever components you like.   

However,  if your project proposal uses an STM32 Nucleo-64 Development Board* We'll Send You a Pair of Boards at the Sub-1GHz Frequency of Your Choice!* 

*There are two versions of this board the NUCLEO-WL55JC2 that handles the 433 to 510 MHz range and the NUCLEO-WL55JC1 that handles the 865 to 928 MHz range.    If you are interested in one of these boards specify which range you are looking for so that we can send you the right board for your project!

Contest Details

imageThe Sub-1 GHz Band contest challenges you to build any project that uses RF communication on sub-1GHz bands like 315 MHz, 433 MHz, 868 MHz or 915 MHz. The sub-1gHz band range includes frequencies used in various wireless communication applications, such as legacy mobile mobile, LoRa, and any number of Internet of Things (IoT) devices.  The sub 1gHz band offers low-power, long-range communication which can extend battery life and wide-area connectivity.  Lower frequency bands are typically less crowded than higher frequency bands, like those used for 4G and 5G, meaning there is more available spectrum in the sub 1 GHz range that can help accommodate a larger number of devices and applications without experiencing heavy interference.   Sub-GHz bands are used in various long-range communication applications, such as emergency services, rural connectivity, and remote monitoring systems.  

Your project could include anything that improves connectivity in rural and remote areas, such as living off-the-grid.   The sub 1gz band is ideal for remote monitoring applications that rely on low-power, long range connectivity with extend battery life.   Other types of projects you could work on include disaster relief projects, wildlife and environmental monitoring, smart city connectivity, low cost healthcare connectivity, and anything related to precision or smart agriculture.   This contest challenges you to design creative and innovative projects that explore the unique advantages of sub 1Ghz bands in any number of real world scenarios.

imageYou are free to use any board  you like for this challenge but to make things more fun we will be giving away a limited number of STM32 Nucleo-64 boards for project project proposals that use them.    The NUCLEO-WL55JC STM32WL Nucleo-64 board provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32WL Series microcontroller, choosing from the various combinations of performance, power consumption, and features. Its got ARDUINO Uno V3 connectivity support and the ST morpho headers provide an easy means of expanding the functionality of the STM32WL Nucleo open development platform with a wide choice of specialized shields.

There are two versions of this board the NUCLEO-WL55JC2 that handles the 433 to 510 MHz range and the NUCLEO-WL55JC1 that handles the 865 to 928 MHz range.    If you are interested in one of these boards specify which range you are looking for so that we can send you the right board for your project!

What are Some Advantages of Sub 1-gHz Band?

While sub 1 GHz frequencies offer several advantages, there's no one-size-fits-all solution to wireless connectivity. Each frequency band has its strengths and weaknesses, and your choice of frequency depends your requirements for the application as well as the environment in which it will be deployed. Higher frequency bands also have their own advantages, such as increased data capacity, which makes them better suited for other types of applications like 4G and 5G cellular networks.

Here are some advantages of Sub 1 GHz Bands:

  • Better Signal Penetration: Sub 1 GHz signals can penetrate obstacles such as walls and buildings more effectively compared to higher frequencies. This characteristic makes them ideal for providing coverage in indoor environments and areas with challenging terrain.
  • Extended Range: Lower frequency signals can travel over longer distances without significant signal degradation. This extended range is beneficial for providing wireless coverage in rural and remote areas where base stations may be far apart.
  • Improved Indoor Coverage: Due to their better penetration capabilities, sub 1 GHz frequencies are well-suited for improving indoor coverage, ensuring that users can maintain connectivity even when inside buildings.
  • Reduced Infrastructure Costs: The longer range of sub 1 GHz signals means that fewer base stations or access points are needed to cover a given area. This can lead to cost savings in network deployment and maintenance.
  • Energy Efficiency: In wireless communication, transmitting at lower frequencies generally requires less power compared to higher frequencies. This energy efficiency is advantageous for battery-operated devices, such as IoT sensors and remote monitoring equipment.
  • Less Susceptible to Rain and Foliage Attenuation: Sub 1 GHz signals are less affected by atmospheric factors like rain and foliage, which can attenuate higher frequency signals. This property can be crucial for maintaining reliable communication links in adverse weather conditions or heavily vegetated areas.
  • Narrowband Compatibility: Some sub 1 GHz bands are allocated for narrowband communication. Narrowband technologies are designed for low data rate applications, such as machine-to-machine communication, and can coexist with other communication systems more efficiently. Legacy System Compatibility: Many existing communication systems, such as older 2G and 3G networks, operate in the sub 1 GHz bands. This compatibility is important for ensuring seamless integration and backward compatibility during network upgrades and transitions to newer technologies.

  • My project: The WRONGCO 433 Mhz wireless morse code key for my "green go kit" amateur radio station. I can send and receive sitting in a lounge chair while drinking a solar chilled tropical beverage. The Latte Panda inside is running Windows 11, and this week, W11 decided the USB->232 converter used to interface the transmitter is obsolete & unsupported. I need to win a new USB converter . :-)
