1. Introduction

1.1 Purpose of the requirements document

This Software Requirements Specification (SRS) identifies the requirements for project StartAir Safe. In case of a open source project, we must present the requirement to others potential contributors. This document is a guideline about the functionalities offered and the problems that the system solves.

1.2 Scope of the product

This project mainly consists of a web application development. This app should allow a hikers team to localise each other in real time. It should be really easy to add new members (Numeric code, QRCode, NFC, …). The system should work whether or not there is a 2G/3G/4G or LoRa connection.

1.3 Definitions, acronyms and abbreviations

LoRa = Long Range : Low powered radio based communication technology
LoRaWAN = Long Range Wide Area Networks : LoRa overlayer to ease (& securise) LoRa communication implementation
LPWAN = Low Powered Wide Area Networks
BLE = Bluetooth Low Energy
GPS = Global Positioning System

1.5 Overview of the remainder of the document

2. General description

2.1 Product perspective

Becoming a worldwide outdoor geolocation leader.

2.2 Product functions

This system should allow low energy cost localisation. It should be decentralized as 2G/3G/4G network is sporadic in such environnement. It should also centralize all data to allow sending it to appropriate services (rescue team for instance).

2.3 User characteristics

Hikers team, comfortable with using a smartphone but not a technology expert. No financial criteria other than having a smartphone as an ESP32 costs about 5€. Age group = any that is comfortable with using a smartphone hence (~15-70).

2.4 General constraints

The system should work whether or not there is a 2G/3G/4G connection Limited localisation accuracy : GPS.

2.5 Assumptions and dependencies

As few environnement assumptions as possible. A team needs at least 1 smartphone (with GPS connection) and 1 ESP32 per hiker.

3.Specific requirements, covering functional, non-functional and interface requirements

document external interfaces,
describe system functionality and performance
specify logical database requirements,
design constraints,
emergent system properties and quality characteristics.
