LongFi is a wireless technology developed by Helium that allows for long-range, low-power communication over the sub-gigahertz spectrum. It is designed for use in Internet of Things (IoT) devices and can provide connectivity in areas where cellular or Wi-Fi coverage is limited or unavailable. LongFi devices can connect to the internet via gateways that act as bridges to the traditional internet, and can be used for a variety of applications such as tracking, monitoring, and control of remote assets.
Longfi technology
LongFi technology uses the sub-gigahertz spectrum, which is less congested and more reliable than the crowded 2.4GHz and 5GHz bands used by Wi-Fi and Bluetooth. This allows for longer range communication and better penetration through walls and other obstacles. The LongFi network is built on a decentralized architecture, which means that anyone can set up a gateway and contribute to the network, providing more coverage and redundancy.
One of the key benefits of LongFi is its low power consumption, which makes it well-suited for battery-powered IoT devices. Devices using LongFi can run on a coin-cell battery for years, making it ideal for use in remote locations or in devices that are difficult to access for maintenance.
LongFi is also designed to be secure and resilient, with end-to-end encryption and multiple layers of security to protect against hacking and other malicious activity.
Overall, LongFi technology is a promising solution for IoT connectivity in areas where other wireless technologies may not be feasible or cost-effective. It can be used in a wide range of industries, including agriculture, logistics, smart cities, and industrial automation.
Helium
This is a network developed in 2013 by American company Helium Systems. It should become the world's first peer-to-peer LoRaWAN IoT network. The network consists of wireless hotspots that provide Internet connectivity for LoRaWAN IoT devices. LoRaWAN is a protocol used by many IoT devices. Through this protocol, these devices can connect to other IoT devices and routers.
Proof-of-Coverage (PoC) is the consensus mechanism used by Helium. This consensus mechanism allows hotspots to cooperate with each other. For example, this algorithm determines who should validate transactions and what compensation someone gets for doing so. Further in this article, we explain the ways you can earn HNT tokens. In addition to PoC, Helium also uses the Honey Badger Byzantine fault tolerance (HBBFT) protocol to achieve agreement within the network. The protocol is very similar to the well-known Byzantine fault tolerance protocol.
