Koonsys takes on designing of point-to-point and point-to-multipoint network, preparation of feasibility study, location the base stations, making of detailed radio-technical and complete frequency plans, setting parameters of network equipments and antennas, licensing, implementing.

During the initial system design, several basic decisions must be made regarding the type of equipment and the configuration which is to be employed. However, before these decisions can be made it is first necessary to establish the volume and type of traffic to be transmitted and where it is to be terminated. It is important that not only the initial traffic requirements be considered but also the needs for future growth. Inaccurate growth forecasting can result in an excessive initial investment if the growth is overstated. Alternatively, predictions, which are too small, can necessitate expensive modification or expansion of the system soon after it is operational.

The next step in the preliminary planning should be to decide on the degree of reliability or availability which the system is required to yield. Most non-technical people posed with such a question would probably respond with answers like: "The best possible, " "It must always be available when needed," or possibly "Communications are vital to be my business and no service interruptions can be tolerated." Unfortunately, these answers are of little value or help to the microwave system design who requires a specific numeric value upon which to base the design. The appropriate selection of this value is of paramount importance, since it will affect many subsequent design decisions and the over-all cost of the system.

Above table provides the relationship between reliability and outage time, but it is almost impossible to predict the duration and frequency of each individual outage, which will contribute to this total value. Further, the outage time will be composed of two different reliability figures. Equipment malfunctions can be expected to be relatively rare, particularly if standby assemblies are furnished, but may be of long duration. If the microwave station is remotely located, it may take an hour or more to dispatch a technician and remedy the fault. Service interruptions due to propagation conditions will be more frequent but of short duration-typically a few seconds. The permissible outage time will affect such factors as:

The major factors which influence the choice of the frequency band in which the proposed microwave system will operate are:

The available microwave bands may be broadly classified as 6, 11, 13, 15, 18, 23 and 38GHz. Within each of these bands, sub-classifications assign specific frequencies to various types of users and the amount of bandwidth (and hence the traffic capacity) which can be employed. The widespread acceptance of microwave radio communication by a variety of users has produced congestion of the limited number of frequencies available, particularly in and around large cities and in the lower frequency bands.

The objective of path is to design a microwave system that meets system traffic and reliability requirements at a minimum cost. The final system path design documentation contains:
