Access and
transmission network

Vodafone’s access networks provide the means by which its customers can connect to Vodafone. The Group provides mobile access through a network of base stations and fixed access through consumer DSL or corporate private wire. These access networks connect back to Vodafone’s core network via its transmission network.

  • Fixed broadband

    The DSL access multiplexer provides fixed line telephony connections enabling customers to connect to the internet via Vodafone.

  • Base station

    Base stations manage the wireless radio transmissions to and from Vodafone’s customers’ mobile devices. They provide coverage over an area known as a cell. The network of cells provides the wide area coverage demanded by customers and aims to provide seamless mobility as they move from one cell to another. Vodafone uses both 2G and 3G mobile technologies.

  • Private wire corporate access

    Vodafone delivers private branch exchange services to its enterprise customers via dedicated private wire connections. Through these the Group delivers the advanced voice and data management needed by corporate operations.

  • Transmission infrastructure

    The transmission infrastructure connects Vodafone access networks to the core network. Vodafone uses a combination of fixed line and wireless (microwave) transmission infrastructure, which Vodafone both owns and leases.

Core network

The core network is responsible for setting up and controlling the connection of Vodafone’s customers to the Group’s voice and data services.

The core network comprises three control domains and a services domain. The different domains and infrastructure within them are connected together via a transmission network.

Circuit switched The circuit switched domain provides voice/video calls and some basic data services. The infrastructure in the circuit switched domain manages the set-up and routing of Vodafone’s customers’ connections to their desired service.
Packet switched The packet switched domain provides Vodafone’s customers access to data services. This includes managing the delivery of data between mobile devices and setting up data connections to Vodafone’s advanced data services and other external networks.
IMSThe IP multimedia subsystem provides advanced control for all internet protocol (‘IP’) services. It enables Vodafone to deliver rich internet based multimedia services and perform flexible blending of different services.
