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.

Zero carbon Internet showcased at Viva Technology 2018 with Green Communications technology

Imagine a world where connectivity is everywhere and has zero impact on the environment. This is happening now. The concept will be showcased at Viva Technology 2018, May 24-26 in Paris by Orange in partnership with Green Communications.

At the entrance of VivaTech show, visitors will discover a Green PI connected station offering public WiFi hotspot and proximity services available on a local web portal.

The standalone station is solar powered, mobile and connects to Internet and with other connectivity stands wirelessly so that one can deploy one or a group of stations with no constrains.

The web portal offers local content and collaborative applications (chat, video, file sharing, etc.) hosted close to the end user to increase the navigation speed and reduce the energy resources used to reach vicinity information.

Green PI is the low carbon impact Internet infrastructure developed by Green Communications. Green PI is composed of low power mesh hotspots with edge cloud and local applications and services.

For more information on Green PI and to meet with us at Viva Technology 2018, please contact us.

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.
