Wireless access networks

Introduction and large scale utilization of digital techniques for signal processing made possible the unification of voice, images and data transmission and this substantially modified the aspect of telecommunications. Wireless access networks may be organized according a cellular pattern or as personal or small office, home office networks with interconnection to a backbone network. 

As wireless access networks can be used mesh or ad hoc networks in connection with the available equipments,  with the covering area and with the services.

It can be emphasize that there are two major items which essentially modified the network access: 

  • Large scale penetration of personal computers in business and in private life, and Internet development dramatically changed the communication and business 
  • Large scale development of mobile communication equipments with various facilities and with new and innovative services.

INSCC implication

  • Establishing and justifying of hybrid access solutions;
  • Dynamic resources allocation and selforganizing in wireless access networks;
  • Virtual access networks;
  • Broadband access technologies;
  • Cooperation between different access technologies in hybrid networks with Wi-Fi, WiMAX and cellular networks, etc.
  • Services in intelligent networks;
  • Comparative analysis for quality and security in wireless access networks,
  • Communication technologies in wireless intelligent networks.

Research Projects

INSCC worked out the following projects within the wireless communications:

  • Integrated communication platform with broadband flexible access, PICABAL;
  • Integrated wireless platform for broadband local access and mobility, with resources selforganization, PABMAR;
  • Analysis and identifying of hybrid solutions for broadband access;
  • Study concerning wireless mesh network;
