Scanzone Cellular Towers

The most important elements of any mobile telecommunication site are the base stations and the antennas. Base stations are normally installed at ground level and antennas are mounted on a support structure to raise them above the clutter of surrounding buildings or trees. Base stations are normally connected directly to the antenna using feeder cable. Base stations can connect to the rest of the mobile phone operators network using a microwave or fibre optic link.

In some installations space can be limited and the base stations need to be installed at a location remote from the antennas. In these instances the base station location and the support structure location are linked using fibre optic cable. At the support structure optical to RF repeaters or remote radio heads are used to connect to the antenna. The repeaters or remote radio heads can be mounted on the support structure below the antennas. The telecommunications equipment will be mounted on a support pole of the SCANZONE at varying heights depending on local requirements.


Locating the base stations in a central hub (Hotel) and using fibre to feed multi-operator repeaters on the SCANZONE support structure.

If there is no space available at the base of the support structure, the base stations can be located at a remote “base station hotel” and a wideband RF to optical distribution system can be used.

The RF output signals from operators’ equipment can be combined, converted to optical signals, and transmitted over fibre to the support structure. At the support structure the optical signals are converted back to RF by a remote unit mounted on the support structure. The range from hotel to the Scanzone unit can be up to 15Km.

Locating the base stations main unit and transmission indoor units in the Scanzone Upper Chamber and mounting remote radio heads and transmission outdoor equipment on the SCANZONE support structure.

Locating the base stations at the base of the SCANZONE support structure.

If there is sufficient space at the base of the Scanzone unit the base stations can be placed there. The base stations can be connected to the antennas using RF feeder cables or optically if remote radio heads are used. Remote radio heads are used to counteract signal losses in feeder cables.

Connection to the operator’s network will be provided by fibre where feasible. If this is not available then an operator will require a transmission dish mounted on the support structure.

The base stations need to be fenced off from the public or be vandal proof.
