Hyperlocalisation and more!

Inspiration

We thought that the accurate location that 5G provides would be perfect for an app that tracks crowds, that could make public events like concerts and sporting events more efficient and safer. We could also leverage the low latency and high reliability to integrate hardware IOT devices and smart sensors.

What it does

We built a service for mass gatherings. You can use an app to figure out where lines are shortest based on data from 5G phone signals. If a room in a building is too crowded, it gives a warning on the app (and also possibly an IOT device at the entrance to the room,) warning people immunocompromised to stay away, and to prevent events like stampedes or building collapses. It integrates with motion sensors, smart lights, sanitary HVAC systems, and door motors!

How we built it

We have three parts: the backend, the frontend, and hardware.

The backend is a server that polls 5G and sensor data, which makes it available through a serverless REST API.

The frontend is a mobile site built in react, that has a map to display routing information and indicators to see crowded areas to avoid, heat map style.

The hardware runs on a tiny raspberry pi zero, custom wired with 3d printed components

Challenges we ran into

Not a lot of time! Also we had a few team members who are new coders.

A lot of us were in different time zones, which made communication tough. Thank goodness for discord though!

3d printing also takes a lot of time, so we could only print so much parts at once.

Also, we had some tech difficulties with Azure (=

Accomplishments that we're proud of

Working across different time zones, and meeting cool people!

Integrating with so many different members

Fixing some tricky bugs on the frontend!

What we learned

About 5G of course, all the cool features!

What's next for Hlo+

Possibly a contract to pilot in an event space, or a large city
