   WiMax technology

Multi-user access system

PURPOSE

   The system of wideband wireless access is intended for creation of wireless “point-to-multipoint” networks and for providing integrated services: high-speed Internet access and communication services.

ADVANTAGES

  • Stable communication under conditions of compact urban development.
  • Flexible traffic distribution among subscribers.
  • Guaranteed support of VOIP technology.
  • Compatibility with the equipment of other firms.
  • Simplicity of expansion.
  • Remote control capability.

COMPONENTS

  • Base station (BS)
  • Subscriber station (SS)
