Long-Range Wireless Internet Breakthrough

Overview

• A world record distance for wireless internet was achieved using the protocol called LoRaWAN.
• The record was set by connecting a fishing boat off the coast of Portugal to a Gateway in the Canary Islands, covering approximately 830 miles (1300 km).

Technology

• LoRaWAN: Utilizes low frequencies (~900 MHz) for long-distance transmission.

  • Advantages:
    • Lower frequency signals travel farther and penetrate obstacles better.
  • Limitations:
    • Data speed decreases over long distances.
    • Typical range: ~5 km in cities, ~10 km in rural areas.
    • Speed: Comparable to dial-up under ideal conditions.

• Wi-Fi Halo: Newer standard with faster speeds but shorter range.

  • Advantages:
    • Range of about 1 km with potential for extended reach in ideal conditions.
    • Speeds range from 150 kbps to 15 Mbps; can perform tasks like video calls.
  • Uses:
    • Primarily for IoT and basic connectivity in rural or special environments.

Practical Applications

• LoRaWAN is beneficial for devices requiring minimal bandwidth, such as:
  • Moisture sensors in agriculture.
  • Transit tracking.
  • Sensors in nuclear plants.
• Amazon’s Sidewalk network and IoT devices leverage these benefits.
• Battery Efficiency: LoRaWAN devices require low power, allowing long-term operation on batteries.

Halo and IoT

• Halo's faster speeds enable varied applications beyond IoT.
• Provides an option for long-distance wireless bridges, translating the Halo signal to conventional Wi-Fi.

Potential Usage

• While not suitable for replacing home Wi-Fi, it can enhance rural connectivity or support IoT applications.
• Offers a solution for basic internet needs in areas with limited infrastructure.
