Introduction
Radio Transmission Paths

Electromagnetic waves, which can be effectively propagated on specific frequencies through free space, are used for implementation of radio transmission. A suitable group of electromagnetic waves is called as radio waves. Radio waves can be divided on the basis of their usage into these several categories (see the following list and figure):

Frequency bands utilized by radio systems

Radio systems may either complement the fixed or wired access resources, especially wherever it is convenient, or you can use them to create a distinct mobile and fixed network providing a wide portfolio of services.

The most economical benefit of radio systems is especially achieved in “hard to reach” areas and locations with sparse population where it is not cost-effective or suitable to build a cable network. The wireless network offers high flexibility, which can be temporarily used in case when the customer requires the connectivity to the network infrastructure immediately (for example concerts, meetings, etc.).
