Overview
Helium walks through the largest wireless network in the world — an IoT network built on the Helium blockchain and powered by token incentives (HNT, trading ~$27.50 with a ~$3.2B market cap at time of demo). explore.helium.com visualizes the hotspots providing LoRaWAN coverage in cities like San Francisco. Helium hotspots (40+ approved manufacturers under the Decentralized Wireless Alliance) plug into power and internet at home, broadcasting a long-range IoT signal for sensors and soon handsets. The live demo uses a Dragino LDS-S01 door sensor: opening and closing the door sends 9-byte packets over the Helium network, picked up by the fittingly named "stable-rouge-puma" hotspot and routed to console.helium.com in real time. The packets flow onward via a Datacake integration into a dashboard — a full end-to-end application built with a cheap sensor and the public network. On the incentive side, the hotspot routing the demo traffic earned ~0.339 HNT over 7 days and ~1.3 HNT over 30 days from proof-of-coverage mining plus a small Data Credit reward for actually carrying the packets.
0:00 Introduction to Helium
Helium has been building what is now the largest wireless network in the world for about three years, on the Helium blockchain. Unlike most crypto, Helium has a very direct utility: sending wireless data for IoT sensors — and soon handsets and computers.
1:00 Explore.helium.com — hotspots on the map
explore.helium.com shows the public blockchain data: a map of hotspots providing LoRaWAN coverage in hexagons. The HNT token trades around $27.50 with a ~$3.2B market cap at time of demo.
2:00 What a Helium hotspot is
A Helium hotspot is a wireless-AP-style device (~40 manufacturers approved by the Decentralized Wireless Alliance) that plugs into power and internet at home, providing LoRaWAN coverage for long-range IoT data.
3:00 HNT utility token and real applications
HNT is a layer-one utility token on the Helium blockchain. Thousands of companies and developers deploy applications on the network — e.g. air-quality monitoring and sensor tracking — with data routed from sensors through hotspots to cloud apps.
4:30 LDS-S01 door sensor live demo
The live demo uses a Dragino LDS-S01 door sensor. When the magnet separates, a packet is sent over the Helium network to tell an application the door is open or closed — a minimal end-to-end proof point.
5:30 console.helium.com packet feed
At console.helium.com, 9-byte packets from the door sensor appear live, with the hotspot that picked them up (named "stable-rouge-puma" from its public key) visible alongside RF and wireless stats.
7:00 Datacake dashboard integration
The console pipes packets to a Datacake dashboard — a partner in the Helium ecosystem — showing how developers wire sensors into full end-to-end applications.
7:30 Hotspot earnings — PoC + data credit rewards
The hotspot routing the door-sensor packets earned ~0.339 HNT over 7 days and ~1.3 HNT over 30 days. Rewards come from proof-of-coverage (PoC) mining plus small Data Credit rewards for actually routing packets.
