=1.  Introduction=

1.1 Purpose of the requirements document
This document aims to clearly define requirements, and so features, for our application, both functional and not-functional. Features presented here are the atomic core of the future application.

1.2 Scope of the product
The scope of the product is to make an application onwhich members of a same network would be able to locate and exchange datas with each other equiped member. This has to be possible for every users (depending on their own equipment) regardless of natural conditions (Weather, Relief) nor network coverage of the area. Optionnal equipement would allow more data knowledge. Scope users could be: -> Urgent signals such as SOS are features specifically for these users.
 * Trailers: Be able to locate themselves, and have a constant possibility of contact with organization team.
 * Hunters: Have a direct visualization of the area covered during a try to regroup beasts. It's also a safety measure to don't shoot an human.
 * Hikers: For organisms like UCPA, could be used to watch children during hiking, preventing any losts. New activities could be created thanks to the application, which only create an easy way to take care of every child at once.

1.3 Definitions, acronyms and abbreviations

 * GPS: Globaml Positionning System
 * LoRaMote: Device able to broadcast his own position using the LoRaNetwork and GPS
 * Module RN2483: Communication module able to send date at specific frequencies, using a USB Sserie-port
 * Group: Network of users, contain at least a Receiver.
 * Users: General term for all members of a group
 * Receivers: Specific users: Have at least an Android Phone with the application running, a LoRaMote and (optionnal) a Module RN2483. They are able to send and receive data
 * Senders: Speciific users: Have at least a LoRaMote and (optionnal) a Module RN2483. Are only able to send their own data.

1.4 References
This is the first year this projet is conducted, and so we do not have previous bases for this specific project. Although, here's an non-exhaustive list of documentation on technologies which are going to be in use:


 * A Book on STM32, 32-bit microcontroller integrated circuits by STMicroelectronics
 * A LoRa Documentation, provided by Orange
 * Semtech LoraMote Documentation
 * Developing IoT Mashups with Docker, MQTT, Node-RED, InfluxDB, Grafana
 * Docker
 * MQTT
 * Node-RED
 * InfluxDB
 * Grafana
 * Leaflet
 * Meteor
 * Code de Base

1.5 Overview of the remainder of the document
In the following parts of the documents, specific features and constraints of usage are detailled. It also quantify the importance of every single one. Finally, ideas of future development are included.

=2.  General description=

2.1 Product perspective
The product will manage a group.

Each user has -> Availability to keep receivers informs on its own position through Lora Network
 * A LoRaMote device, making him visible for each receiver.

-> Can manually launch specific signals such as SOS

Each receiver has: -> Availability to keep other receivers informs on its own position and various data through 3G or Lora Network
 * (Optional) A bluetooth equipement such as GPS watch or cardio belt.
 * Module RN2483
 * An Android Running and Bluetooth friendly Smartphone

-> Can catch and display on the Smartphone information broadcasted by all users.

-> Can interact with other receivers for specific information

Public Restrictions

LoRa Network uses Public Radio Frequencies, and so the traffic on these frequencies is limited. The application has to be data-friendly in order to respect these regulations.

2.2 Product functions
Senders:
 * Automatic broadcast on Lora Network its own GPS position every quantum of time. Quantum would be predefined considering battery life and accuracy.
 * Manual SOS signal through Lora Network with a physical SOS button.

Receivers:
 * Automatic broadcast on Lora Network and/or 3G its own GPS position every quantum of time. Quantum would be predefined considering battery life and accuracy.
 * Manual SOS signal through Lora Network with a physical SOS button.
 * Catch all GPS broadcasted information and display it on an OpenStreetMap powered map. Show also computed data such as distance, speed (using data history)...
 * (Optionnal) Receive near data using bluetooth and provided by specific equipements (Cardio belt, GPS watch...) and broadcat it using LoRa Network and/or 3G
 * Catch all data broadcasted display all available data as further information on a clic on a point of the map, representing an user.

2.5 Assumptions and dependencies
=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.
