NearFi | Highly configurable proximity Wi-Fi repeater

Introduction

This project is a proximity Wi-Fi repeater based on ESP32 SoCs by Espressif. The most interesting feature of this project is the possibility to alllow the acces to the generated Wi-Fi network to people that are very close to the device to connect with a download speed up to 12 Mbps and a upload speed of 10 Mbps.

Why?

I decided to develop this project to improve the security and functionality of small business Wi-Fi networks, to ease the process of providing Wi-Fi credentials to customers and to control available bandwidth.

How does it work?

Device configuration requires the ESP SoftAp Provisioning application, which is available for Android and iOS, to provisioning Wi-Fi credentials. When configured, the device generates an open Wi-Fi network that only allows Wi-Fi clients with an RSSI below a threshold to connect. The process is fast and does not require any human intervention.

Features

• Download speed up to 20 Mbps
• Upload speed up to 10 Mbps
• Support up to 15 clients connected at the same time
• OTA updates
• Can be powered by any USB source (5V)
• RGB LED to indicate device status
• Connection distance approximately less than 40 cm
