KIRK 500

KIRK 500 is a microcellular system of the DECT standard with one base station, a maximum number of subscribers of up to 8 and a maximum number of repeaters of up to 6.

Microcellular system of DECT standard - KIRK 500 (manufactured by KIRK Telecom, Denmark) - an ideal solution for organizing wireless communication of a small office, cottage, store, warehouse, etc. On the basis of the KIRK 500 system it is possible to build a microcellular communication system consisting of 7 zones (1 base station + 6 repeaters).

The coverage area is limited to 30-50 meters indoors and 300 meters outdoors. The communication range is highly dependent on the materials and design of the room in which the system is installed. The coverage area can be increased by using repeaters.

The system is a radio extender of analog PBX ports (8 ports). Connection switching is performed by the PBX. The system is connected to an existing office mini-PBX via analog two-wire connection lines and allows the use of up to 8 mobile telephone sets.

The controller is powered by a 9V adapter.

Modification of KIRK 500-E for directional antennas
A special modification of the KIRK 500 system (KIRK 500-E) is made in a moisture- and dust-proof case. It has two TNC connectors for connecting directional antennas, allowing to increase the radio coverage area in a given direction.

It is advantageous to use the DECT system in this design in open areas to connect remote landline subscribers. For example, when organizing communications in a cottage village, or if cable laying is difficult due to terrain, as well as for organizing temporary communications when cable laying is not economically viable. The maximum distance to a stationary terminal subscriber radio unit (TARB) is 5000 m. The maximum distance of a mobile subscriber in the coverage area of a directional antenna is 600...1000 m.
The maximum distance of the subscriber terminal from KIRK 500-E depends on the type of selected antennas.

Architecture of the DECT system KIRK 500
Structurally, the KIRK 500 system is made in a plastic case, combining the system controller and one base station, which provides communication within a radius of 30-50 meters indoors and up to 300 meters outdoors.

The KIRK system can be connected to both a newly acquired institutional PBX and an existing one. An analog two-wire interface is used for connection, each mobile subscriber has one connecting line with the PBX (a total of 8 lines per system).

It is possible to connect the system in parallel to existing analog PBX subscribers.

Application of repeaters
The base station coverage area can be increased by using repeaters. Up to 6 repeaters can be used in the system, up to 3 of them can be combined into a chain (see diagram).

Repeaters are placed around the office/enterprise territory in such a way that their coverage areas partially overlap with the base station and with each other, ensuring full coverage of the office/enterprise territory.

The architecture of the system when using KIRK 500-E differs only in the shape and extent of the coverage area. The use of directional antennas allows you to form coverage areas depending on the topography of the area and the location of objects.
