The current world population as of April 2020 is to be at 7.8 billion people. And all those people need to eat. In order to more efficiently provide healthy crops to feed billions of people, technologies are continuously being developed and refined to help with sensing, processing, and transporting agriculture.
One technology that’s critical for IoT solutions in smart farming is Wi-Fi. Though most of us nowadays just take Wi-Fi for granted in our daily activities, there are many interesting and novel ways it is powering smart farming solutions.
Wi-Fi for Smart Farming
Because it’s easy today to reach an outdoor range of up to 300 feet outdoors with just a single router, Wi-Fi can be used to support rather cutting-edge technologies for many small to medium applications. Wi-Fi also now utilizes multiple frequencies, so that data transfer is generally quick and readily available.
One clever example of a small-scale smart farming solution is which relies on Wi-Fi to connect and share information directly between smart indoor farms and restaurants/markets. The process is simple and user-friendly– a restaurant/marketjusthas toplug intheirFarmshelf, connect toWi-Fi, and a smart LCD screenwill guide theirstaff through the growing process.
LPWAN for Smart Farming
For large farms, smart farming often needs a longer-range wireless solution. Also, many of these large farms are in remote locations, using solar or batter powered transmission devices.
In these situations, a low-power, wide-area network (LPWAN) is the preferred technology. In today’s global smart farming industry, there are three leaders in LPWAN technology:
LoRa /LoRan- named for its“LongRange” specificity was developed by French startupCycelo and then in 2012.CurrentlySemtech controls much of the technology’s core IP and is consideredby many to have setthe LPWAN standard.
NB-IoT – this “NarrowBand” LPWAN technology has been designed to provide simple solutions for industrial and agricultural IoT applications
Although LPWAN devices can cover a longer range, the trade-off is a limit to data transfers. Though it’s easy enough to send data from a humidity or soil pH sensor, you wouldn’t want to stream 4K video, even though this might be useful in showing important real-time imagery of significant crops.
LPWAN is also not as readily available,sincemost of today’s current infrastructure is designed to support
high-bandwidth communication instead. However, a growing market for smart faming solutions may soon lead to new advances.
GPS/GNSS for Smart Farming
Another important wireless technology that’s been crucial for smart farming is theGlobal Positioning System (GPS) that is currentlyin the process of being replaced by the more advancedGlobal Navigation Satellite Systems (GNSS).
In smart farming, global positioning is needed for tracking, for example herds of animals and sometimes agricultural drones! John Deere is a pioneer in developing that are used to guide farming equipment and track data to improve equipment control and efficiency.
