Green Communications offers a technology for the final part of the BLR (Boucle Locale Radio) to connect customers with quality of service while saving energy. It provides network equipments containing virtual resources which are capable in both wired and wireless to set up efficient networks that use the lowest possible energy and resources. This is achieved mainly by two tools, routing and virtualization. The routing can optimize the routes and supports the quality of service especially for Ad-hoc/Mesh networks. In addition, virtualization based on the special routing algorithm moves the network virtualized resources on specific equipments to optimize their use and reduce the consumption energy of those not overloaded.
