LoRa (Long Range) Radio Network

[yoursteamfriend.royce]

Foogle search results direct you towards a new and upcoming network communications spectrum that is being handed down from military and police to the general public. Preppers go bonkers over it, and HAM radio enthusiasts can only gawk at the newfound tech hitting the civilian market.

You are directed to the website Peaceful Networks, providing the new chipsets. They are not cheap, not yet - affordable enough to add to any prepper's kit. Perhaps in another timeline these chipsets would become widely available and highly cheap and sought after on the civilian, prepper, disaster relief...and even criminal markets.​

LoRa (Long Range) radios are low-power, long-distance wireless communication devices ideal for the Internet of Things (IoT) (IoT), using a special Chirp Spread Spectrum (CSS) modulation to send small data packets over kilometers with minimal power, enabling long battery life for sensors in smart cities, agriculture, and asset tracking, often using unlicensed sub-gigahertz radio bands. It's the physical layer, while LoRaWAN is the network protocol built on top, managing devices and gateways.

Key Characteristics

• Long Range, Low Power: Achieves kilometers of range with very low energy use, far exceeding Wi-Fi or Bluetooth, allowing devices to run for years on batteries.
• Chirp Spread Spectrum (CSS): A unique modulation technique that spreads signals across a wider frequency band, making them robust against noise and interference, and allows them to be detected below the noise floor.
• Low Data Rate: Optimized for sending small, infrequent data bursts (e.g., sensor readings) rather than high-bandwidth streams, with speeds from 300 to 50,000 bits per second.
• Unlicensed Bands: Operates in free-to-use ISM (Industrial, Scientific, and Medical) bands (e.g., 868 MHz, 915 MHz), though regulations on usage frequency exist.
• Built-in Security: Includes encryption for secure data transmission.

How It Works (LoRa vs. LoRaWAN)

• LoRa (Physical Layer): This is the radio technology itself—the chips and modulation (CSS) that encode data onto radio waves for long-distance, low-power transmission.
• LoRaWAN (Network Protocol): This is the network architecture that uses LoRa hardware. Devices (nodes) talk to gateways, which relay data over IP networks to a central server, creating a complete network.

Common Applications

• Smart Cities: Parking sensors, waste management, smart lighting.
• Agriculture: Soil monitoring, irrigation control, livestock tracking.
• Industrial IoT: Remote asset tracking, equipment monitoring.
• Smart Metering: Reading water, gas, or electricity meters remotely.
