No description of communication technologies would be complete without covering the part closest to the customer, the access network. In order to reach our multiple customers with widely varying requirements, we make use of multiple access network technologies.
Optical fibre is typically used to connect our largest customers, delivering a single dedicated route, or multiple services (voice, data, Internet) over a single high bandwidth pipe with maximum reliability and with the option of a redundant ring feed.
Within metropolitan areas, where the amount of bandwidth consumed is highest, our optical fibre infrastructure forms Metropolitan Area Networks (MANs), which, in addition to all of the services described above, also supports Ethernet (the familiar Local Area Network protocol) as a cost-effective, high bandwidth means of linking offices.
Digital wireless technologies are able to connect customers rapidly and without the need for physical cabling. The largest sites are typically connected via point-to-point microwave radio carrying one or more services. We also make use of point-to-multipoint wireless access technology to connect multiple large customer sites in one area.
WiMAX technology is used for wireless broadband services, offering a reliable alternative to copper.
Gigabit optical networking (GPON) technology is used in some areas to provide cost effective delivery medium for Ethernet based services.
