VietnameseStay connected with friends at festivals when the network is overloaded
Thousands of phones, one overloaded cell tower. At a busy festival, mobile service slows to a crawl right when your group splits up. Nelos keeps you in touch over your own local radios instead.
One cell tower, tens of thousands of phones
A festival site wasn't built with cell capacity for a sudden crowd the size of a small city. When everyone nearby is trying to text, call, or post at the same time, the local tower runs out of capacity - messages queue, calls drop, and "send" just spins. It has nothing to do with your phone; the network itself is overloaded.
Your own local network, independent of the venue
Nelos connects your phone to a small compatible LoRa device over Bluetooth. Your group's phones talk to each other over that local radio network directly - not through the venue's cellular towers or Wi-Fi.
Group chat that keeps working
Message your crew without waiting on a congested network to catch up.
Find each other
See everyone's last known position on a shared map when the crowd splits you up.
Share a meeting point
Drop a spot to regroup and everyone in the crew can see it.
Need Help
One tap lets your crew know you need help, along with your exact location.
Split up at the main stage
Your group scatters during a headline set - some people push toward the front, others hang back near the food stalls. Texts aren't going through on the packed venue network. On Nelos, the group chat keeps moving, and a quick "meet at the big tree by gate 3" message gets everyone back together without anyone standing around waiting for a bar of signal that isn't coming.
A compatible device for each person in your crew
Nelos needs a compatible LoRa device paired over Bluetooth to actually send and receive over the mesh - the app alone, with no device, can't do that. See the devices guide for compact, easy-to-carry options.
Dense crowds and stage structures can affect radio range like any obstacle would, so it's worth testing with your group before the event, not during it.

Frequently asked questions
Do I still need a device if I have the app?
Yes. Nelos itself doesn't create a network - it connects to a compatible LoRa device over Bluetooth, and that device is what actually sends and receives over the mesh. Installing the app alone isn't enough.
Does this rely on the festival's Wi-Fi or cell towers?
No. Your group's messages and locations travel over your own compatible devices, not the venue's network. That's exactly what keeps it working when the venue's cellular service is overloaded.
Will it work in a huge crowd with everyone's phones nearby?
A crowd of phones doesn't compete for your mesh the way it competes for cell towers, but dense crowds and stages can still affect radio range. Keep expectations realistic and test with your group before you rely on it.
Can I send a Need Help alert if I get separated?
Yes. One tap sends a Need Help alert with your exact location to the rest of your group, so they know where to find you.
