The mining operation covers from Amamapare on the coast, 120 Kilometres inland to an altitude of over 4,200 metres. It is one of the few places in the world where glaciers still exist on the mountain peaks. The Fylde equipment provides complete coverage of all open face and underground tunnel mining stretching a distance of over 54 Kilometres.

Radio coverage for tunnels is provided by fibre optic cell enhancers supplied by AFL. The main trunked repeater equipment and antenna combining remains on the surface but the antenna is replaced by a fibre optic transmitter/receiver. Thus the entire radio spectrum needed by the radio network is converted into light.

The hub of the trunked radio network is located close to the support operations and the airfield in an area called LIP. One of the trunk radio sites is also located here. It is at this point that the radio sites served by fibre and microwave, many hundreds of PABX circuits and the inter-continental satellite links come together. The satellite link connects the island with North America.

One important feature allows Fylde personnel access to the Irian-Jaya network from the U.K through an I.P gateway at Freeport H.Q in New-Orleans. Through this gateway, Fylde are able to interrogate and configure any hub or any channel on any site in real time. The large dish carries the satellite traffic to Freeport HQ in North America.
