Green PI explained in a short video

Green PI is a low carbon impact Internet and Edge Cloud platform providing digital services to users and smart devices with speed, mobility, high resiliency, and data sovereignty. Watch Green PI in action on this short video.

What is Green PI?

Green PI consists in:
1.Edge network of mobile nodes
A node is either a smart device equipped with Green PI’s software (the GreenSoft) or one of the embedded IoE platforms offered by Green Communications. Nearby nodes communicate directly and form an autonomous wireless Internet infrastructure offering high-bandwidth connectivity to end-users and devices;

2. Edge cloud distributed near users
Green PI federates the computing capacity of edge network nodes to create an edge cloud distributed near end-users and devices. An edge cloud can count tens network nodes and hundreds client devices. One may scale up the edge cloud federating edge clouds operating in multiple locations and creating an Internet of Edge (IoE);

3. A set of low carbon impact digital services
Green PI’s edge cloud hosts digital services at the data source to ensure, low latency, quick server response time and resilience to Internet interruption. Edge-based services are distributed in each Green PI’s network nodes to allow nodes’ mobility without disrupting a service. The short travel of bits of information from source to server through the edge cloud releases the Internet network from unnecessary traffic and save on datacenter resources. Thus, participating significantly to reducing Internet’s carbon footprint.

Three Fire Departments Will Deploy Green PI as a Direct Communications System

Green Communications is awarded of the Innov’up Tech & Rescue Experimentation call for projects and wins the privilege to deploy and experiment Green PI as a direct communications and edge system with firefighters of Essonne, Yvelines and Seine-et-Marne fire departments.

Since no existing solutions nor infrastructures are proposing a direct communication mode, firefighters could encounter problems to share voice, video and data during interventions. Public and private infrastructure-based networks could be destroyed, inactive, attacked or jammed. The direct multihop and edge solution proposed by Green Communications is moving along with the firefighters for facilitating rescue interventions in constrained environments.

We would like to thanks Atraksis, the Île-de-France region and Bpifrance who organized this call for projects and to congratulate all the winners McLloydMoten TechnologiesEVERSATArt Graphique & Patrimoine. We are now looking forward to starting the deployments.

5G: All You Need to Know

At a time when 5G is being deployed around the world, the book “should we be afraid of 5G”, written by Guy Pujolle, Emeritus Professor at Sorbonne University, pioneer in high-speed networking and, Co-Founder and President of Green Communications, answers all the questions that arise from a technological, social, environmental and political point of view to unravel the true from the false and understand everything about 5G!

Guy Pujolle is an eminent expert in computer science and telecommunications. He was at the origin of several inventions and important patents like DPI, Wi-Fi controller, and virtual networks. Guy Pujolle received several prices for his work and publications, in particular the Grand Prix of French Academy of Sciences in 2013.

Green Communications’ Swarm of Drones Project Was Awarded a Seal of Excellence by the European Commission

Swarms of drones usually operate under the coverage of GNSS* and LTE/ Wi-Fi infrastructures. Green Communications innovates and creates fully autonomous swarms that can operate without infrastructure and in GNSS denied environment. Thus, using the Green PI technology combined with Artificial Intelligence (AI). Green Communications’ solution of swarm of autonomous drones was scored as a high-quality project and was awarded a Seal of Excellence by the European Commission.

For more information on the Green PI technology and its application on drones, please, contact us.

Green Communications connects the firefighters of Ille-et-Vilaine (France)

The call for tenders of the fire department of Ille-et-Villaine (SDIS 35) for a stand-alone Wi-Fi mesh network is attributed to Green Communications.

In a context of natural or man-made disaster, rescue forces need connectivity to make use of the SINUS application for the counting and identification of victims. Green Communications proposes a rapid deployable Wi-Fi infrastructure composed of a set of weatherproof Wi-Fi mesh nodes featuring 19 hours of battery life based on its Green PI low power and lightweight mesh devices.

Green Communications releases a stand-alone mobile Mesh network for the rapid set up of an Internet infrastructure with autonomous applications and services.

The system comprises:

  • A set of handheld Mesh routers (YOI)
  • Batteries of 20h autonomy and more
  • A YOI-4G/LTE to connect Green PI to other networks
  • Embedded applications (Voice and video over IP, chat, file storage, web, etc.) for autonomous work.

Within minutes, one can extend the coverage of a private LTE or a mobile 4G network inside buildings, tunnels and to remote areas by simply turning ON the YOI devices. This sets a Green PI network up providing both local-based services and global Internet access through the YOI-4G/LTE gateway.

Green Communications delivers customized Green PI Mobile Networks with additional YOI, gateways, battery life and services upon request.
